The global food crises of 2008 and 2010 and the increased price volatility revolve around biofuels policies and their interaction with each other, farm policies and between countries. While a certain degree of research has been conducted on biofuel efficacy and logistics, there is currently no book on the market devoted to the economics of biofuel policies. The Economics of Biofuel Policies focuses on the role of biofuel policies in creating turmoil in the world grains and oilseed markets since 2006. This new volume is the first to put together theory and empirical evidence of how biofuel policies created a link between crop (food grains and oilseeds) and biofuel (ethanol and biodiesel) prices. This combined with biofuel policies role in affecting the link between biofuels and energy (gasoline, diesel and crude oil) prices will form the basis to show how alternative US, EU, and Brazilian biofuel policies have immense impacts on the level and volatility of food grain and oilseed prices.

AbstractThere is a great deal of variability in estimates of the lifetime medical care cost externality of obesity, partly due to a lack of transparency in the methodology behind these cost models. Several important factors must be considered in producing the best possible estimate, including age-related weight gain, differential life expectancy, identifiability, and cost model selection. In particular, age-related weight gain represents an important new component to recent cost estimates. Without accounting for age-related weight gain, a study relies on the untenable assumption that people remain the same weight throughout their lives, leading to a fundamental misunderstanding of the evolution and development of the obesity crisis. This study seeks to inform future researchers on the best methods and data available both to estimate age-related weight gain and to accurately and consistently estimate obesity's lifetime external medical care costs. This should help both to create a more standardized approach to cost estimation as well as encourage more transparency between all parties interested in the question of obesity's lifetime cost and, ultimately, evaluating the benefits and costs of interventions targeting obesity at various points in the life course.

Traditional economic theories assume that individuals are endowed with certain risk preferences that are unaltered by experiences. However, recent evidence indicates that macroeconomic shocks do have an effect on an individual's willingness to take financial risks. In the context of investment decisions, we examine empirically whether an individual's risk preferences are affected by other types of traumatic life experiences. Using a unique proprietary data set, we investigate whether personal traumatic experiences—such as the combat experiences of veterans—have long‐term effects on financial risk‐taking behavior. We find that having experienced combat decreases the probability of investing in risky assets. Key policy implications are noted. (JEL G11, D14)

AbstractA conceptual framework is advanced that determines world biodiesel prices, the policy parameters in the country establishing the price, and the binding mandate or tax exemption. The effect of a tax credit differs with international trade compared to traditional closed economy analysis. The U.S. "splash & dash" program, with its $1/gallon tax credit, had minimal impacts on European Union (EU) biodiesel producer profits. Reduced world oil prices and EU tax exemptions, as well as increased rapeseed oil prices, are shown to have reduced the profitability of EU biodiesel production. EU imports from the United States can be beneficial for EU taxpayers, fuel consumers, and U.S. biodiesel producers.

Abstract.  State‐sponsored lotteries are a lucrative source of revenue. Despite their low payout rates, lotteries are extremely popular, particularly among low‐income citizens. State officials laud the benefits of lottery proceeds and promote the fun and excitement of participation. This entertainment value is one explanation for lottery demand by the poor: individuals with lower incomes substitute lottery play for other entertainment. Alternatively, low‐income consumers may view lotteries as a convenient and otherwise rare opportunity for radically improving their standard of living. Bad times may cause desperation, and the desperate may turn to lotteries in an effort to escape hardship. This study tests these competing explanations. We examine lottery sales data from 39 states over 10 years and find a strong and positive relationship between sales and poverty rates. In contrast, we find no relationship between movie ticket sales, another inexpensive form of entertainment, and poverty rates.
