Cost Benefit Analysis and the Approaches to World Hunger.    Bjorn Lomborg discusses the use of cost-benefit analysis. 

"Providing micronutrients -- particularly vitamin A and zinc -- to 80% of the 140 million or so undernourished children in the world would require a commitment of just $60 million annually, a small fraction of the billions spent each year battling terrorism or combating climate change. The economic gains from improved productivity and a lower burden on the health system would eventually clear $1 billion a year. Every dollar spent, therefore, would generate economic benefits worth $17.Investing in research to make technological improvements to developing-country agriculture provides the opportunity to improve access to micronutrients. It also reduces the cost of food by increasing the incomes of landless laborers. Biofortification can be achieved through genetic modification, or through other methods. Spending $60 million a year would be enough to develop two staple crops such as rice and wheat fortified with micronutrients for about 40 countries across South Asia and sub-Saharan Africa.  The improved nutrition would lead to higher productivity and fewer health problems. Each extra dollar spent would generate economic benefits worth $16."

And, unlike grain-based ethanol, it doesn't need rain or prime farmland, and it doesn't distort global food markets. NASA has estimated that halophytes planted over an area the size of the Sahara Desert could supply more than 90% of the world's energy needs."   A for-profit company is doing research on this.

May's American Economic Review.   Papers from the January 2008 meetings contain a lot of things relevant to AREC 365.

 

(1)  Institutions and economic development.  Easterly:  "After all this research and experience [showing formal land titling was frequently ineffective], the aid donors today remain stuck on some kind of idealized comprehensive (top down) government reform that would somehow make formal registration of land titles 'optimal.'"   Rodik:  "Yet this literature [suggesting that appropriate institutional arrangments in one country may be inappropriate in another country] appears to have had very little impact on operational practices. The type of institutional reform promoted by multilateral organizations such as the World Bank, the IMF or the ...WTO is heavily biased toward a best-practice model."

 

(2)  Height, Health and Economic Development.  Case and Paxson:  "[T]he advantages offered by a healthier early life environment—as measured by height—follow adults into old age. We use several waves of data from the Health and Retirement Study (HRS) to document the extent to which height is associated with more favorable outcomes for individuals above the age of 50. We find that taller men and women have greater cognitive function, measured on a wide variety of dimensions."    Deaton fails to find a consistent link between distribution of income and distribution of height   "Indeed, even the link between mean height and income is far from established (see particularly the analysis of global heights and income in Deaton 2007) where there is no relationship between mean height of women and GDP in the year of birth across poor countries in Asia, Africa, and Latin America."  Peracchi looks at the relationship between income and height in Italy.

 

(3)  Psychology and Development.  Duflo, Kremer, and Robinson :  "Many countries have withdrawn or scaled back fertilizer subsidies, in part because of fiscal constraints, corruption, and inefficiency in the administration of fertilizer subsidies, but also because of a belief among economists that farmers would choose to use inputs that actually raised profits in real-world conditions. ...  Behavioral economists have identified major departures from economists’ standard models ...However, it is still unclear whether these departures have any major impact on production. Fertilizer offers an attractive context to explore this question.  In this paper, we use a series of field trials on Kenyan farms to explore the most natural hypothesis: the possibility that, while fertilizer and hybrid seed increase yield on model farms, they are actually not profitable on many small farms, where conditions are less than optimal. Our mean estimates of yield increases due to fertilizer use are in the range of the estimates found on model farms. We find that the mean rate of return to using the most profitable quantity of fertilizer we examined was 36 percent over a season, or 69.5 percent on an annualized basis. However, other levels of fertilizer use, including the combination of fertilizer plus hybrid seed recommended by the Ministry of Agriculture, are not profitable for farmers in our sample."   Banerjee and Mullainathan "Economists have long been interested in the idea that there is a direct circular relation between poverty and low productivity, and not just one that is mediated by market failures, usually in asset markets. The nutrition-based efficiency wage model (Partha Dasgupta and Debraj Ray, 1987) is the canonical example of models where this happens: However it has been variously suggested (see for example T. N. Srinivasan 1994) that the link from nutrition to productivity, and especially the link from productivity to nutrition, is too weak to be any more than a small part of the story. Dasgupta himself acknowledges this when he writes that the “nutrition-productivity construct provides a metaphor … for … an economic environment harboring poverty traps” (Dasgupta 1997, 5)."

A "Controlled Experiment" in Famine.  At the end of WWII, Nazi-occupied Netherlands experienced severe food shortages (the hongerwinter, or "hunger winter"), with average food intake estimated at 1000 calories per person per day, and some with diets as low as 400-800 calories per day.   The famine was short-lived, lasting only a few months in late 1944 and early 1945, and ending abruptly with the Allied victories in May 1945.   This situation, and the existence of precise birth records, created an unplanned "controlled experiment" by which children born, or in-utero during the famine could be compared to children born before and after the famine.    The study of the Dutch Famine Birth Cohort has generated a number of studies that identify the impacts of maternal undernutrition on unborn children.

Cost-Benefit Analysis and Hard Decisions. This is not a hypothetical example.  The bad news:  you have incurable cancer and are very likely to die within one year.  The slightly less bad news:  There is a drug you can take that will prolong your life by 3 to 6 months, so that your life expectancy becomes 15-18 months, instead of a year.  The conundrum:  The drug will cost $125,000 to $150,000.    If you had to pay the cost of the drug yourself, would you use it,  reducing your children's inheritance by $125,000-$150,000?  If you have health care through a government program such as Medicare, should that program pay for the drug?  Doctors Without Borders says that they can protect a child from undernutrition for $62 a year, or for about $1000 (using a 2% discount rate) for the child's first 18 years of life.   If you had to bear the cost of the cancer drug, would you use the money to extend your own life by 3-6 months, or would you donate the money to Doctors Without Borders to protect 125-150 children from undernutrition during their developmental years?    If a government program is bearing the cost of the cancer drug, would the tax money be better spent on those children?

Biofuels causes food prices to increase 75%?   According to the Guardian, a "confidential World Bank Report"  by senior economist Don Mitchell expanded biofuels production have caused food prices to increase 75%.  Of course without seeing the report, we can't know how this number was arrived at (or even know for sure whether such a report exists).  But the June WASDE puts corn used for ethanol at 4000 million bushels (or 100 MMT) -- about 13% of world corn production of 775 MMT.  If non-biofuel demand for corn has an own price elasticity of -0.10  a 75% price increase would reduce that demand by 7.5%,  and if corn supply has an own price elasticity of 0.07, a 75% price increase would increase supply by 5.25%,  so the combination (7.5+5.25 = 12.75) is about the amount needed to account for biofuels demand.  These elasticities seem to be a little on the low side, especially the supply elasticity number, and this may make the 75% number too high.  For example if demand elasticity is -0.15 and supply elasticity is  0.15, the impact of ethanol is to increase corn price by 43%.  And of course, this is the direct effect on corn, not the effect on all food.

If There Is a Food Price Bubble, How Will it End?   Charles Kindleberger, in his book Manias, Panics, and Crashes  (and there is a newer edition) notes that bubbles don't just burst at their peaks.  Rather they peak, then slowly deflate, and then burst.  (So maybe there is a fault in the imagery of a "bubble.")  For example, the "bursting" of the stock market in October 1929 followed a peak of stock prices in August 1929, followed by 2 months of flat and slightly declining prices.

"As the speculative boom continues, interest rates, velocity of circulation, and prices all continue to mount.  At some stage, a few insiders decide to take their profits and sell out.  At the top of the market there is hesitation, as new recruits to speculation are balanced by insiders who withdraw.  Prices begin to level off.  There may then ensue an uneasy period of ”financial distress.” ....  For an economy as a whole, the equivalent is the awareness on the part of a considerable segment of the speculating community that a rush for liquidity --- to get out of other assets and into money --- may develop, with disastrous consequences for the prices of goods and securities, and leaving some speculative borrowers unable to pay off their loans.  As distress persists, speculators realize, gradually or suddenly, that the market cannot go higher.  It is time to withdraw.  The race out of real or long-term financial assets and into money may turn into a stampede."

So if the current high food commodity prices are in part caused by bubble psychology, we might expect not a sudden bursting at the peak, but rather a period of flat and slightly negative growth and then the sudden sharp decline in price.  Gallegati, et al.,  suggest that this phenomenon is seen not just for asset price bubbles, but also for commodity price bubbles (silver prices in the late 1980s) for which there is a "real" supply (production) and "real" demand (consumption).    So is the moderation of wheat prices in April and May of 2008 the presage of an even sharper decline as we move through the summer?    And would we have (mistakenly) seen the flatness in October - December 2007 (months 28-30 in the graph below) as a predictor of a sharp price decline?
