UNNATURAL CAUSES: AN ATTACK ON ‘UNNATURAL’ AGRICULTURE?

I recently came across ‘Unnatural Causes’ a 7 part documentary about racial and economic inequalities in public health. I have not watched it, but I did download the policy guide :


The main theme seems to be (that) ‘Building a social movement that can advocate effectively for more equitable social policies is critical to changing our economic, physical, and social environments so they can promote rather than threaten our health.’

On the surface, this does not seem so bad, but many of the policies they recommend in doing this show a lack of understanding of economic science and modern agriculture. Since economics is the study of our choices and how they are made compatible in a world of scarce resources, their neglect of economics leads them to adopt many policy recommendations that are incompatible with their stated goals.

Policy recommendation #9 : Improve Food Security and Quality, recommends among other things that we support ‘sustainable agriculture and local food production, especially organics.’

Now I don’t have a specific problem with organic food as long as it is not promoted at the expense of modern science and agriculture. Agriculture is a competitive industry and I believe that there is a niche for everyone including local/organic producers, but their explicit mention of organic and their failure to mention biotech options implies the exclusion of biotech.

This is not consistent with their goal of sustainability,considering the environmental, safety, and health benefits of biotech foods that organics could never provide such as the elimination or decreased use of toxic chemicals ( organics use harmful ‘natural’ chemicals like copper sulfate and mercuric), decreased tillage ( which organics depend upon heavily) and improved biodiversity ( tillage and use of broadcast Bt in organic production is detrimental to non-target pests and ecosystems).

One example is Bt corn( a biotech crop). Not only does it eliminate the use of millions of pounds of insecticide and save millions of gallons of fuel and water per year, but it also is safer for food consumption. The use of Bt corn decreases fumonisin ( a fungal parasite) infestation by 80% compared to conventional and organic corn. Fumonisin is responsible for esphogeal cancer and neural disorders in infants.

Another example is Roundup Ready technology. Roundup Ready technology has allowed for glyphosate herbicide to substitute for 7.2 million pounds of other chemicals that are more toxic and persistent in the environment.

They also talk about reforming the ‘subsidy program’ that regards the producers of processed foods. They must be talking about nonrecourse loans. If they assume that these ‘subsidies’ lead to an increase in supply and result in cheap input prices for large processors, then they should wake up to see current commodity prices.

Given that they also mention multiple times throughout the policy guide that they support increased taxes, I assume they would support doing away with non-recourse loan programs and instead increase the income and inheritance taxes on grain farmers. In place I’m sure they would like to implement actual subsidies for local and organic growers.

Let’s just hope this propaganda does not make it on the local news or into school curriculums.

DO INDIVIDUALS HAVE THE RIGHT TO KEEP AND BEAR ARMS?

Usually I don't write posts this long, but in light of the coming Independence Day holiday, and recent supreme court decision, both the length and the subject matter of this post are an exception.

The second amendment reads as follows:

‘A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.’

This language is very confusing to many, and for those that take it out of the context of history, and our founders writings about its purpose, many are led to believe that the right to keep and bear arms only applies to the militia, which in modern terms may be our military or national guard.

Note however, from the start, it does not state that ‘A well regulated militia, being necessary to the security of a free state, the right of the PEOPLE IN THE MILITIA to keep and bear arms, shall not be infringed.’
If we understand the plain language of the 2nd amendment, and especially if we look at it in the historical context in which it was written, we will see that the 2nd amendment is a compromise to forming a militia at all, due to the fears that the anti- federalists and the people at that time had of standing armies under the control of a centralized government.

We would see that well armed citizens are in fact a pre-requisite for the existence of the militia, as opposed to the view that the pre-requisite for citizens to be armed is that they be in the militia.

Federalist #29 and #46 give us context for this understanding. Federlist # 29 states:

‘If circumstances should at any time oblige the government to form an army of any magnitude, that army can never be formidable to the liberties of the people while there is a large body of citizens, little if at all, inferior to them in discipline and the use of arms, who stand ready to defend their rights and those of their fellow citizens.’

This statement clearly distinguishes the militia or the army from the citizen, and implies that the citizens may be armed, and in fact it is absolutely necessary that they be armed to defend their rights if need be. It did not imply that the militia would defend our rights, but that ‘a large body of armed citizens would defend themselves from an army of any magnitude, and this would include the possibility that they may need to defend themselves from even the militia. While the militia may be composed of armed citizens, it was assumed that other armed citizens, not in the militia would hold it in check. This could not be so if there was no individual right to keep and bear arms.

In Federalst #29, we see that there is a notion that our national military be composed of armed citizens, called to duty when the need arises. Some feared that perhaps this loose collection of soldiers may not be strong enough to keep us safe, but also feared a large strong standing army. A compromise was introduced, such that a small select group of citizens should form a select militia, to train regularly, and in time of need be supplemented by drawing on the ranks of other armed citizens. As stated:

‘The attention of the government ought particularly to be directed to the formation of a select corps of moderate extent…it will be possible to have an excellent body of well trained militia, ready to take the field whenever the defence of the state shall require it.’

Would this small select militia be a threat to the liberties of the people? What about our national defense? Only if individual citizens had the right to keep and bear arms to supplement the small select militia and also to keep it in check would this work. In fact our founders were certain of the strength and power of armed citizens, drawing recently from the experience of a victorious war against England’s powerful military. Again going back to Federalist #46 it is stated:

‘Besides the advantage of being armed, which the Americans posses over the people of almost every other nation, the existence of subordinate governments, to which the people are attached, and by which the militia officers are appointed, forms a barrier against the enterprises of ambition……the military establishments in several kingdoms in Europe, which are carried as far as the public resources will bear, the governments are afraid to trust the people with arms.’

Again, a reason and reaffirmation that it was intended that the second amendment protect the rights of individuals to keep and bear arms.

There is a distinction made between this select militia and citizens, a point made in the recent case DISTRICT OF COLUMBIA ET AL. v. HELLER (2008):

"The Amendment’s prefatory clause ( the well regulated militia part) announces a purpose, but does not limit or expand the scope of the second part , the operative
clause. The operative clause’s text and history demonstrate that it connotes an individual right to keep and bear arms."


"The “militia” comprised all males physically capable of acting in concert for the common defense. The Antifederalists feared that the Federal Government would disarm the people in order to disable this citizens’ militia, enabling a politicized standing army or a select militia to rule. The response was to deny Congress power to abridge the ancient right of individuals to keep and bear arms, so that the ideal of a citizens’ militia would be preserved."

I will end my discussion with other quotes made by our founders and others discussing the constitution and the right of the people to keep and bear arms.

"That the said Constitution shall never be construed to authorize Congress to infringe the just liberty of the press or the rights of conscience; or to prevent the people of the United States who are peaceable citizens from keeping their own arms ... " -- Samuel Adams, Debates and Proceedings in the Convention of the Commonwealth of Massachusetts, at 86-87 (Pierce & Hale, eds., Boston, 1850)

"Whereas civil-rulers, not having their duty to the people duly before them, may attempt to tyrannize, and as military forces, which must be occasionally raised to defend our country, might pervert their power to the injury of their fellow citizens, the people are confirmed by the article in their right to keep and bear their private arms."
-- Tench Coxe, in Remarks on the First Part of the Amendments to the Federal Constitution


"The right [to bear arms] is general. It may be supposed from the phraseology of this provision that the right to keep and bear arms was only guaranteed to the militia; but this would be an interpretation not warranted by the intent. The militia, as has been explained elsewhere, consists of those persons who, under the laws, are liable to the performance of military duty, and are officered and enrolled for service when called upon.... [I]f the right were limited to those enrolled, the purpose of the guarantee might be defeated altogether by the action or the neglect to act of the government it was meant to hold in check. The meaning of the provision undoubtedly is, that the people, from whom the militia must be taken, shall have the right to keep and bear arms, and they need no permission or regulation of law for the purpose. But this enables the government to have a well regulated militia; for to bear arms implies something more than mere keeping; it implies the learning to handle and use them in a way that makes those who keep them ready for their efficient use; in other words, it implies the right to meet for voluntary discipline in arms, observing in so doing the laws of public order."-- Thomas M. Cooley, General Principles of Constitutional Law, Third Edition [1898]

"The most foolish mistake we could possibly make would be to allow the subject races to possess arms. History shows that all conquerors who have allowed their subject races to carry arms have prepared their own downfall by so doing."-- Adolph Hitler, Hitler's Secret Conversations 403 (Norman Cameron and R.H. Stevens trans., 1961)

In the context of our history and our founder’s writings, we see that the clause regarding the militia fails to limit in any way the rights of the people to keep and bear arms. In this context the following statement is certainly equivalent to the one in question, being the 2nd amendment:

‘Because a well regulated militia is necessary for the security of a free state, and because it both draws from the ranks of ,and its power is held in check by, armed citizens, the right of the people to keep and bear arms shall not be infringed.’

DO WE BLAME SPECULATORS?

With the increase in commodity prices, including agricultural and energy futures, many critics have come down hard on speculators. Some are calling for more regulation including increased margin requirements, or requirements for players to actually take delivery of the products.

These critics seem to forget that the role of futures markets is to provide risk management tools to suppliers and producers of commodities. Speculators provide the liquidity to make this possible.

Futures prices, like any other price, have an important social function in transmitting information, providing incentives, and allocating resources. It is in the interest of speculators to search out information related to the relative scarcity ( now and in the future) of commodities. The potential for profit provides the incentive to do so. Further, as ‘speculation’ drives up the price of scarce commodities, it provides incentives for producers to increase supply and for consumers to find substitutes or reduce consumption. As a result we get an optimal allocation of commodities over time, as opposed to catastrophic shortages or surpluses.

The proposed regulations on commodities markets will likely reduce this consumption and production smoothing process, and increase the volatility of commodity prices. Most importantly, the information transmission function of commodity prices would be inhibited. As a result, knowledge about the relative scarcity of commodities may not be as complete or timely making things much worse than we can imagine today.

OBESITY AND CLIMATE CHANGE

Recently in the news there was a story about environmentalists targeting obese individuals as being major contributors to global warming. When the interviewer basically asked how an obese individual’s carbon footprint fromsitting on the couch all day compared with someone like a skinny Barbie girl that went to work, drove to a smoothie bar and had an organic smoothie, then drove to a climate controlled gym and spent 2 hours utilizing their electric powered equipment before stopping by the local organic market on the way home compared, they quickly changed the subject.

They immediately attacked meat consumption. I’ll admit, it is probably true that someone that eats a healthy well balanced diet probably has a lower carbon footprint than others. However, there is no reason that beef could not be part of a healthy diet, considering that there are 29 cuts of lean beef that have barley more than 1 gram more of saturated fat than a comparable serving of skinless chicken breast. In addition beef delivers many times more iron, zinc and vitamin B12.

It may be true that beef consumption requires more fuel to produce than say rice, but you are getting a lot more nutrition from beef than rice. Further, it does not make sense to focus so narrowly on one aspect of our lives when it comes to energy consumption and GHG’s ( greenhouse gas). We all know how much fossil fuel consumption and GHG production results from driving automobiles, but we don’t stop driving. Instead we focus on improving emissions and efficiency.

In the same way with beef, improvements in genetics, nutrition, and management will ( and have) lead to less pollution, and increased efficiency with regard to how much food we are getting from a given amount of animal units, land, water, and other resources ( especially compared to 'hormone free' and 'organic' meat production).

Despite rhetoric in the media, there is no scientific consensus to support the drastic sort of changes that these people want us to make in our lifestyles to combat climate change. If you read the IGPCC’s 4th Assessment report, all you will find is that there is a ‘consensus’ agreement that humans have contributed to increased temperatures over the last 100 years with about 90% certainty. When it comes to the changes to our environment, violent storms, draught, and loss of coastal areas, the consensus amounts to a coin toss. When economists take the consensus science about climate change into account, they find that the damage from implementing Kyoto style policies on a magnitude similar to what Al Gore or the ‘Stern Report’ advocates would be worse than doing nothing at all.

With congress debating a GHG emissions bill next week, let’s hope our political candidates and representatives are responsible about what they do in this regard.

Markets and Resource Allocation & The Knowledge Problem

The economic problem of society is more than just achieving an optimal or just allocation of resources. It is easy to formulate a ‘positive’ solution mathematically, where P = marginal rate of substitution between any two goods or factors of production, balancing the costs and benefits of some activity. It is easy to state a ‘normative’ solution of what we believe to be a ‘just’ or ‘fair’ distribution of resources.

However, according to Hayek, the information necessary for any solution for allocating resources in society is seldom sufficient for effective government or bureaucratic decision making:

“the knowledge and circumstances of which we must make use never exists in concentrated or integrated form, but solely as the dispersed bits of incomplete and frequently contradictory knowledge which all the separate individuals possess.”

The economic problem of society becomes “ the problem of the utilization of knowledge not given to anyone in its totality” but held by individuals.

Hayek proposes two methods for allocating resources 1) market prices and competition ( decentralized) 2) Planning ( total control by government or socialism)

The best system will be the one that is most effective at “putting at the disposal of a single authority (government) all the knowledge which ought to be used but which is initially dispersed among many different individuals, or in conveying to the individuals (free markets) such additional knowledge as they need in order to enable them to fit their plans in with those of others”



How does Government Obtain its Information

Government obtains much of its decision making information through the gathering of data and statistical analysis. However, this data is aggregated and very static compared to the knowledge held by individuals, or the “knowledge of the particular circumstances of time and place.”

Because individuals are involved in ‘the rapid adaption to changes in the particular circumstances of time and place, and it would seem to follow that the ultimate decisions must be left to people who are familiar with these circumstances, who know directly of the relevant changes and the resources immediately available to meet them.” Only individuals have knowledge of “the relative importance of the particular things with which he is concerned.”

This sort of knowledge by its very nature according to Hayek “cannot enter into statistics and therefore cannot be conveyed to any central authority in statistical form.” There fore government decisions are inherently doomed to be made with poor information and error, measured in terms of costs to individual well being and preferences.


How can markets be used to make the best use of information critical for the use of resources?

Hayek has an answer in that “in a system where the knowledge of the relevant facts is dispersed among many people, prices can act to coordinate the separate actions of individuals.”

Unlike with government, by making use of the price system, individuals do not have to directly possess all of the relevant knowledge in society to make decisions regarding the use of the resources at their disposal. Hayek states that is “because their limited individual fields of vision sufficiently overlap so that through many intermediaries the relevant information is communicated through all” This is due to the fact that everyone faces prices which reflect the relative tradeoffs between all of the possible alternative uses of resources.

PARADE Anti-antibiotics

According to a recent article in ‘Parade’ included in my Sunday paper, “Sens. Ted Kennedy (D., Mass.) and Olympia Snowe (R., Maine) introduced a bill to end the practice of feeding antibiotics used to cure human illnesses to chickens, cattle, sheep and pigs.”

Link:“Taking Antibiotics Out of Our Meat” MARCH 2ND 2008
http://www.parade.com/articles/editions/2008/edition_03-02-2008/Intelligence_Report

This article is confusing the use of sub-therapeutic feed grade antibiotics with those used to treat human illnesses, or is at least failing to make the distinction clear. It is my understanding that demonstrable rates of gain can be made by adding low levels of antibiotics to feed rations and these antibiotics are not the same drugs used to fight infection in humans.

Most antibiotics used in the livestock industry are used for treating, controlling, and preventing disease. Only 13% are used to improve nutritional efficiency and enhance growth. Despite fears related to antibiotic use in livestock and resistance in humans, no scientific link has been found.

In fact the health consequences of reducing antibiotic use in animals could have far more serious implications. This may sound counter intuitive to what’s reported in the media. However, in Denmark where some feed grade antibiotics have been banned, an increased reliance on therapeutic usage (30%) has resulted because of the increase in animal sickness. The same thing happened in Sweden as well. Let it be known that this increase may also include increased use of drugs that happen to be vital for human health.

Even after reviewing the science behind feed grade antibiotics, if consumers still want ‘antibiotic free’ beef, there is certainly a market for it. However, politicians and activists should not make political ‘hay’ from these interests by promoting feeding regulations that may endanger the health of consumers as a whole, not to mention our environment by mandating less efficient beef production with a larger envrionmental footprint.

Organic Biotechnology

Given all of the environmental and health benefits from biotech foods, you would think that more supporters of organic production and 'sustainble agriculture' would be supportive of biotech crops. I'm not here to bash organic production, because I think that there is a market for everyone. However, research indicates that one shortfall of organic food is its exclusion of biotech/GM crops.

A recent Boston Globe article makes this point:

  • Link


  • Europeans are very skeptical of biotech crops but accept nanotechnology. They also are very supportive of organic production. I wonder how most organic consumers view nanotechnology? Even if it benefits the environment?

    On another note, most people probably don't know that even organic wheat varieties used for making organic pasta come from germplasm that was developted using mutation breeding i.e. introducing genetic variation by mutations casued by gamma rays. I wonder how they feel about that? What is more radical or more unnatural? If we really wanted 'all natural' corn, we'd have to eat the grass-like plant - teosinte- that's ultimately where we got modern corn.

    TAX CUTS AND BUDGET DEFICITS IV

    I concluded my last entry on tax cuts and budget deficits by stating that there could be cases theoretically where Mankiw’s assumption about the failure of Ricardian Equivalence could be true.

    I did provide some empirical evidence for a case where his conclusions about the detrimental effects from deficits failed to materialize as a result of the Regan tax cuts. What about other cases? If tax cuts lead to wealth effects and the failure of Ricardian Equivalence, then empirical evidence should show the following:

    A correlation between tax cuts and an increase in demand, decrease in savings, and an increase in interest rates.

    An increase in current account deficit ( if we are required to borrow from foreigners to finance tax cuts)

    In an effort to see if these relationships hold up empirically, I provide the following literature review:

    1) Carroll & Summers (1987) “ Why Have Private Savings Rates in the United States and Canada Diverged”? Journal of Monetary Economics. Sept 1987, 20 249-279

    Observed that Canada had higher budget deficits that the US from 1983-1985, but also had higher savings rates.

    2) Evans, Paul. “Do Budget Deficits Affect the Current Account?” Ohio State University Aug 1988. unpublished.

    Cross country data for post WWII Canada, U.S., Canada, France, Germany and U.K. showed no correlation to budget deficits and trade deficits.

    3) Robert Barrow. Macroeconomics- 5th Edition MIT Press 1997

    4) Barro, Robert J. ‘The Ricardian Approach to Budget Deficits.” Journal of Economic Perspectives. Vol 33, No 2 (sp 19890 p. 37-54.

    1948-1983 data revealed that the ratio of total output to government budget surplus and net foreign investment had a very weak correlation, and a correlation of only .37 only in 1983.

    5) Plosser, Charles (1982) p.339. “Government Financing Decisions and Asset Returns.” Journal of Monetary Economics. May 1982, 9, p. 325-352.

    Found no correlation between the interest rate on government and various other securities and budget deficits.

    6) Paul Evans (1987). “Do Budget Deficits Raise Nominal Interest Rates: Evidence from Six Industrialized Countries. Journal of Monetary Economics Sept 1987, 20, 281-300

    Looks at interest rates from 1974-1985 and quarterly data for 6 countries, finding no relation between interest rates and budget deficits.

    7) Paul Evans. “Interest Rates and Unexpected Future Budget Defecits in the United States.” Journal of Political Economy. February 1987, 95, 34-50.

    Looks at U.S. data 1931-1979. Current and past defecits had no correlation with nominal interest rates on commercial paper, corporate bonds, or realized interest rates on commercial paper.

    BUDGET DEFICITS AND TAX CUTS III

    In my previous post, I concluded with findings by Mankiw that if consumers are uncertain about their future incomes and tax liability, Ricardian Equivalence may fail. This assumes that deficits are produced from the tax cuts.

    What if there are no deficits? Then there will be no need to raise taxes in the future and no reduction in output in future periods.

    Often the Regan tax cuts are cited as an example of poor public policy. The mantra goes that tax cuts for the rich generate deficits, which in turn lead to higher interest rates and a sour economy. The poor suffer, in addition to economic growth.

    However, if government consumption stays constant, a tax cut now may not require an increase in the future if tax collections actually increase such that no deficit occurs. This may happen if marginal tax cuts increase the after tax value of the marginal product of labor and after tax marginal productivity of capital, leading to more production and output. With more output, a larger taxable revenue base results in more tax collections.

    Lawrence Lindsey ( 1987) noted that for incomes greater than $200,000 per year, the Regan tax cuts lead to an increase in reported incomes and increased collections. For those earning > $200K per year, we saw the following increases in collections:

    1982 – 3%
    1983 – 9%
    1984 – 23%

    In his book ‘The Vision of the Annointed', Thomas Sowell points out the following: ( he obtained this info from ‘Budget of US Government: Historical Tables'. U.S. Government Printing Office, 1994.)

    YEAR REVENUE in billions
    1981 599
    82 618
    83 601
    84 666
    85 734
    86 769
    87 854
    88 909


    Each year, in the face of, and in the wake of large tax cuts, revenues increased. Therefore, it seems we have a situation with marginal tax rates where either Ricardian Equivalence will hold approximately, or tax cuts for the wealthy could actually have a simulative effect. I suppose we could reach a point ‘on the laffer curve’ where tax cuts would not lead to an increased revenue response. In that case, if RE fails as Mankiw believes, negative effects from deficits could occur.

    TAX CUTS AND BUDGET DEFICITS II

    My recent post on tax cuts and budget deficits concluded that evidence does not support the contention that wealth effects result from tax cuts, or that deficits have detrimental effects on interest rates as a result of wealth effects. However, when income taxes are considered, the economy will respond to differences in the timing of taxes.

    Because taxes on income and capital affect the after tax marginal product of labor, and after tax return on investment, taxes vs. deficits during different periods may affect the allocation of work, production, and investment over time. A consequence of this may be that if the government cuts taxes today to stimulate the economy then in the next period when the deficit is settled, or taxes are raised, there may be a reduction in output. These opposing reactions still approximate the Ricardian Equivalence result.

    It has been proposed that Ricardian Equivalence may fail if the permanent income hypothesis fails to hold across time. ( if the permanent income hypothesis holds, then a temporary increase in income- from a tax cut- would have a minimal impact on spending) If households believe that their future tax liabilities will be high in the future ( to settle a deficit) only if their incomes are high, then they may have less incentive to save a tax cut. In this case a wealth effect is created and they increase consumption. These results would then lead to the problems so often associated with tax cuts and deficits.

    TAX CUTS AND BUDGET DEFICITS (Part 1)

    While this blog focuses mainly on environmental and agricultural issues, I do occasionally discuss more general economic issues, as there are often important linkages to agricultural economics. While having lunch I recently overheard a conversation at another table regarding tax cuts. This person was discussing the benefits of tax cuts- perhaps stimulative, and the costs of deficits. A few years ago I studied these issues in depth in graduate level macroeconomics, but this inspired me to re-visit the literature.

    A major concern is with deficits that may result from tax cuts. According to the traditional Ricardian Equivalence ( R.E.) result, people are indifferent to a tax cut now, and higher taxes in the future to pay for covering the resulting deficit. Tax cuts ( if saved/invested) in the current period provide enough resources to cover the deficit in the future, and provide no wealth effect.

    It is the wealth effect that is the problem. If people feel wealthier from a tax cut they may spend more, this leaves less money for settling the deficit. The government has to borrow from fewer resources to cover the deficit, and upward pressure is exerted on interest rates. In the long run this leads to less investment and is detrimental to economic growth. In addition, if other countries are loaning the funds to cover the deficit ( through the purchase of government securities), then our balance of trade is affected.

    Why might there be wealth effects? One reason is finite lives. People may feel that they can spend the tax cut and pass the debt on to future generations. Another reason often given for wealth effects is imperfect loan markets. People that are restrained from spending because they have little collateral or face high transaction costs in getting loans to finance spending, see the tax cut as a loan that must be paid back in the future ( via higher taxes). Only, the rate at which their future taxes will increase is less than the high interest rate they would have to pay for a loan equivalent to the tax cut ( providing that they can even get such loan). As a result, a tax cut leads to spending among this group of people.

    The reasoning behind finite lives is often refuted with examples of bequests, or long-term investment vehicles that have returns based on a market that factors in future tax liabilities. The imperfect loan markets argument, if it holds, implies that deficits are good in that they would improve the functioning of loan markets. Much empirical research indicates that these mechanisms for wealth effects fail to lead to increases in interest rates.

    So, when it comes to lump sum taxes at least, consumers are indifferent between tax cuts now and settling deficits in the future with higher taxes in the future. Empirical evidence does not support the contention that wealth effects result from tax cuts, or that deficits have detrimental effects on interest rates as a result of wealth effects.

    i.e. we may not see much stimulus from the current stimulus package that includes a lump sum tax refund, but the resulting deficit may not be something to worry about either since there likley won't be any wealth effects.

    CARBON CREDITS

    Recently I attended a forum on the possibility for local growers to sell agricultural carbon offsets to the Chicago Climate Exchange. Besides the possiblility of extra income, cabon credits would encourage the use of no-till, which preserves the soil structure, reduces runoff and water pollution, and improves biodiversity within the soil. Reduced tillage practices also imply a decrease in fossil fuel use ( it takes much less fuel to no-till corn than to run plows and harrows through the soil). Another environmental benefit of no till is that it favors the use of biotech crops that have superior environmental benefits. Crops resistant to glyphosate herbicide, and those that express the Bt insecticide trait are ideal in no-till situations, and require the use of fewer or no toxic chemicals.

    Carbon credits represent a serious approach to climate change policy. As renowned climate economist William Nordhaus states in his review of the Stern Review on Climate Change “proposals resulting in increased fuel efficiency for cars, requiring high efficiency light bulbs, subsidizing solar and wind power ..are largely fluff.” Fuel economy standards can actually have lethal side effects. The National Academy of Sciences 2001 report on CAFE standards estimates that the lethal impact of CAFE related changes in automobile designs resulted in the loss of 1300-2600 lives per year.

    Carbon credits effectivly put a price on carbon, which sends a signal to consumers about their ‘carbon footprint.’ Higher carbon prices would provide the incentives for the type of technological change necessary for dealing with climate change.

    BIOTECHNOLOGY: CONVERSATIONS WITH FARMERS

    The following link will take you to a video- commentary from scientists and poor subsitance farmers in developing countries.

    I know this is a corporate sponsored site, so critics will have their biases, but I think the testimonials speak for themselves. If ever there were a consensus about global warming, the scientific consensus about the improved safety and benefits of biotech crops more than corroborates the positions held in this video.

    While politicians are making political hay with a potential global warming crisis, ( with warnings about food shortages, droughts, etc.) there is very little press about the role biotechnology can play in dealing with not only future changes in climate, but the billion people in the world today living on less than a dollar a day.

    GLOBAL WARMING POLICY APPROACHES

    Carbon taxes are the method preferred by many economists with regard to combating climate change. The other alternative would be a Kyoto style cap and trade system. Both methods can be structured to capture the value of the estimated externality of carbon emissions ( the negative effects of climate change). I tend to favor a cap and trade system, but there are problems with market volatility, and rent seeking. (however there is still a lot of money to be made by favored businesses from regulating carbon, even with a tax).

    The problem is balancing the economic costs of policy today today with the economic and ecological benefits of reduced climate change in the future. This can be approached by determining just how to value any negative externality associated with carbon ( or any greenhouse gas). This is not done easily.

    This value is estimated by Nordhaus ( Using the DICE-2007 model, and based on the science of the IPCC Fourth Assessment) at about $30/ ton, with the average person in the US generating about 5tons/yr, for a total of about $150/year, or .09 /gallon of gas and .01/kwh for electricity. However, according to Nordhaus, the Stern Proposal for reducing global warming estimates the damage from global warming to be closer to $300/ton carbon for the next two decades. It would reduce the estimated damage from global warming by $13 trillion, but at a cost of $27 trillion. In this case we are looking at increasing gas with a $1.20/gallon tax.

    There are also proposals to give vouchers to low income people to compensate them for the increased burden of the tax. But, one of the greatest tools for fighting poverty ( and environmental degradation in many cases) is economic growth and technological change. We should look critically at which policies provide the best science based trade-off.

    DEFINING CONSENSUS

    If we accept the IPCC 4th Assessment Report as consensus, we get the following conclusions:

    9/10 experts agree humans have net warming effect p.4

    We are 66% certain human influence has been enough to affect storm patterns p.6

    We are 50% certain humans have affected heatwaves and droughts p.6

    We are 66% certain we will see drastic climatic events ( cyclones, storms, droughts) p.8

    There is a 90% chance we will see increases in temperature extremes p.8

    *Probabilities defined on p. 3 of introduction of actual report.

    The U.N. Intergovernmental Panel on Climate Change's 4th assessment report (2007) predicts that the sea level may rise between 18 and 59 cm (~ 7-23 inches dividing by 2.54) by 2100 (p.13, summary for policy makers).

    So, according to the major consensus view, there is still quite a bit of uncertainty about the effects of global warming, and these consequences are predicted to be much milder than “sea levels rising by more than 20 feet with the loss of the shelf ice in Greenland and Antarctica, devastating coastal areas worldwide” as depicted in ‘An Inconvenient Truth. While this may happen, the time frame is over thousands of years as opposed to the ‘consensus’ view for the next century.

    What economists must do then, is take this consensus science into account, and approximate what the price of carbon should be to limit economic damages from CO2. This level will be achieved where the marginal cost of reducing carbon emissions is equal to the benefits of decreased damages from climate change in the future.

    EXTERNALITIES: Holes in Markets

    In previous posts I’ve discussed that when resources become scarce prices rise and they are used in a way that is more sustainable. I also noted how free markets incorporate the consideration of future generations when resources are used. The conclusion is that free markets are consistent with the optimal use of resources, and the crisis mentality that calls for massive government intervention is unfounded. Many critics of this position claim that there are many ‘holes’ in markets that call for government action.

    Theoretically, many holes in arguments for markets have been described as negative externalities or commons problems. An example would be the consumption of pork. In producing and consuming pork, the producer and consumer may not take into account the impact that a concentrated animal feeding operation may have on air or groundwater pollution. It would appear that in this case a negative externality exists because there is a divergence between the private and social costs of producing and consuming pork.

    Whenever the cost of one’s behavior is not factored into a price by which a choice can be valued, a commons problem or negative externality exists. As Coase (1960) and Demsetz (1967) point out, with the establishment of property rights and markets (bargaining) the externality of the commons can be internalized. Behavior is changed or altered to account for the negative impact our choices impose on others. This framework, part of what is known as the Coase Theorem, closes many of the holes in arguments for free markets.

    Relating to our pork example, if negative externalities exist, it is due to the fact that there are poorly designed property rights to water and air. Groups like Ducks Unlimited and the USDA have caught on to this and are using market incentives to mitigate such pollution problems. Recently the USDA implemented a Water Quality Credit/Trading program. Even the KYOTO Treaty is based loosely on this logic with CO2Cap and Trade provisions.

    CONSIDERING FUTURE GENERATIONS IN RESOURCE USE

    In a previous post, I mentioned that policies can be evaluated by the net benefits that they produce. Does this analysis consider the impact on future generations? How do we deal with situations in which costs are imposed on people in the future as a result of our actions today. Alternatively, how do we justify incurring costs today, for the benefit of future generations. ( both of these questions are relevant in the case of global warming).

    The benefits of future generations are compared to the costs of current generations via the present value concept.

    Example: If a policy implemented today (such as CO2 emissions caps) produces benefits equal to ‘x’ trillion dollars in the future, then we take the present value of ‘x’ billion dollars and compare it to the costs of the policy today. If the policy produces net benefits in present value terms then it may be a favorable pursuit.

    Note, discounting future benefits back to today’s dollars does not imply that we are giving greater weight to our well being today vs. the well being of future generations. PV discounting only allows us to compare costs today with benefits tomorrow in ‘common units.’ It also recognizes that there are opportunity costs to devoting resources today to certain policy ends. ( i.e. often the appropriate discount rate used in PV analysis for public policy may be reflect the opportunity cost of capital. This is relevant because productive capital itself can have a mitigating effect on environmental problems such as global warming).

    COST BENEFIT ANALYSIS AND MARKET PRICES

    In most all cases, benefits and costs used to evaluate the efficiency of a policy are measured in dollar terms. Dollar prices are often used in this estimation because they reveal how people value scarce resources. This is what may be referred to as ‘use value.’ Economists also recognize ‘non-use value,’ or the value or benefit that people conceive from simply knowing that resources exist. ( ex: you may get non-use value from simply knowing that bald eagles have not become extinct etc. regardless if you ever benefit from their existence in some direct financial way.) Of course, these values are much more difficult to quantify.

    Without market prices, economists often rely on survey data or data provided by the physical and natural sciences. Both revealed ‘use-value’ and approximated ‘non-use’ value are converted into monetary terms to provide a common unit of measure. This is not to say that we can put a price on everything, and this does not give greater weight to ‘markets vs. nature,’ it just provides a common unit of measure. This is no different than converting from meters to feet etc.

    In the end, if total benefits translated into monetary terms exceed costs, ( the policy produces positive net benefits) then the policy is said to have a favorable cost/benefit analysis, at least from a pareto-potential perspective.

    This does not mean that the policy should be undertaken, just that it may be favored over an alternative with negative net benefits. There are plenty of other criteria that must be considered such as constitutionality, distribution, rent seeking, etc. ( see ‘Public Choice’ under selected topics)

    EASY MONEY OR FINANCIAL INNOVATION?

    In earlier posts ( Discretionary Monetary Policy I-III) I presented a brief overview of a hybrid monetarist/Austrian view of bubbles and business cycles. This explained the bursting of the ‘agriculture bubble’ in the 70’s, the tech bubble in the 90’s, and I related it to recent sub-prime mortgage issues.

    Certainly these ideas are not my own, but just my application of certain ideas from macroeconomics, and many people may disagree, or be in denial about an infallible fed. But, there are many who offer corroborating analysis. As Gerald P. O’driscoll (former vice president of the Dallas Fed) notes in his Cato Institute article ‘Our Subprime Fed,’

    “ The Fed cut the fed funds rate sharply after the bursting of the stock market bubble in March 2000…..the Fed cut rates far too long, fueling not only a vigorous economic expansion but also the housing bubble.”

    Wayne Angell, a former Fed governor and personal advisor to Dick Cheney is quoted in a recent Fortune article;

    "The Fed was extremely easy from 2002 to 2005. It was not desirable or necessary, and it set off this huge real estate boom.”

    So, the idea that easy, discretionary monetary policy by the Federal Reserve played a role in recent sub-prime mortgage troubles certainly has merit among some prominent economists.

    However, one thing cautioned as far back as my undergraduate coursework in money and banking, was the role that financial innovation and technological change may play when modeling the macro economy or predicting the effects of monetary policy. In the 90’s people were touting that information technology, debit cards, ATM’s etc were changing the way we must view money. In addition, IT made workers more productive, allowing expanded economic growth for a long period of time with very low unemployment without ‘overheating’ or triggering inflation. Of course, the tech bubble soon burst after that.

    In ‘The Bear Flu and How it Spread,’ a recent Business Week article explains the role of financial innovation in the collapse of two Bear Stearns hedge funds. It describes a tweaked version of collateralized debt obligations ( CDO’s) that they tagged ‘Kilo’s. They were designed to encourage money market funds to get involved in the mortgage market by having other large banks such as Citigroup and Bank of America guarantee the investments. To the money market manager, there were decreased risks, and better returns from mortgage products vs. the traditional short term investments used historically. The big banks received fees and more fund sources for ultimately securitizing their mortgages, and Bear Stearns was profiting from selling these new innovative investment products.

    Of course, with this model being repeated throughout the real estate and financial sector of the economy, a downturn could create problems, and it apparently did. One question of course, is what played a larger role in the grand scheme of things, easy money or financial innovation? It is hard to know. One thing is true, the market distortions and noise created by discretionary monetary policy make it hard to determine any thing for certain.

    WHY AGRICULTURAL ECONOMICS

    "The combination of quantitative training and applied work makes agricultural economics graduates an extremely well-prepared source of employees for private industry. That's why American Express has hired over 80 agricultural economists since 1990."
    - David Edwards, Vice President-International Risk Management, American Express


    While in graduate school, and deciding upon the traditional course work in economic theory vs agricultural and applied economics, my advanced micro theory instructor ( from a course taken at the University of Kentucky) posed the following scenario. He said

    ‘ You can choose to be a consumer of economics, or you can be a producer of economics.’

    Phrased differently, he was asking, at what level of mathematical abstraction do you want to work. Do you want to use mathematical tools to model and solve problems of economic significance,( a consumer of economics) or do you want to develop the mathematical tools to be used by other economists to build models and solve problems ( a producer of economics).

    Perhaps it is also a question of basic vs. applied research. I want to see application and results. I want answers to questions now. I don’t want to wait 10+ years for my ideas to either catch on or be forgotten.


    To quote, from Johns Hopkins University’s applied economics program home page:

    “Economic analysis is no longer relegated to academicians and a small number of PhD-trained specialists. Instead, economics has become an increasingly ubiquitous as well as rapidly changing line of inquiry that requires people who are skilled in analyzing and interpreting economic data, and then using it to effect decisions ………Advances in computing and the greater availability of timely data through the Internet have created an arena which demands skilled statistical analysis, guided by economic reasoning and modeling.”

    Ultimately I chose a graduate program in Agriculture with an emphasis in Agricultural Economics. I had some trepidation at first, thinking that it may have a limited focus. Actually, it lead to encounters with the same theoretical and quantitative tools presented in traditional graduate work in economics, and also provided additional opportunities for application (such as natural resource and energy economics or biotechnology). At my institution, I was able to take additional courses in crop science and genetics to tailor a secondary emphasis in Agronomy. I also had the opportunity to take courses in applied economics and finance from the MBA program.

    To quote from the American Agricultural Economics Association:

    “Nearly one in five jobs in the United States is in food and fiber production and distribution. Fewer than three percent of the people involved in the agricultural industries actually work on the farm. Graduates in agricultural and applied economics or agribusiness work in a variety of institutions applying their knowledge of economics and business skills related to food production, rural development and natural resources”
