| Previous work in experimental economics reveals specific differences in economic behavior, especially reciprocity and free-riding behavior, across cultures. We expand the possible pallet of cross-cultural behavioral differences that may exist. We hypothesize that different kinds of strategic interaction and individual decision-making behaviors differ across locations. The variety of experiments we use allow us to report multidimensional rather than just single dimensional differences in behavior across locations. In order to build a broad Homo Economicus we conducted economic experiments in four dissimilar locations: Hangzhou, China; Niamey, Niger; Grenoble, France; Manhattan, Kansas; and West Lafayette, Indiana. Each subject completed an ultimatum... |

| The recent rise in world oil prices, coupled with heightened interest in the abatement of greenhouse gas emissions, has led to a sharp increase in domestic biofuels production around the world. Previous authors have devoted considerable attention to the impacts of these policies on a country-by-country basis. However, there are also strong interactions among these programs, as they compete in world markets for feedstocks and ultimately for a limited supply of global land. In this paper, we evaluate the interplay between two of the largest biofuels programs, namely the renewable fuel mandates in the US and the EU. We examine how the presence of each of these programs influences the other, and also how their combined impact influences global markets and... |

| The passage of U.S. laws mandating and subsidizing advanced cellulosic biofuels may spur the development of a commercial cellulosic biofuels industry. However, a cellulosic industry will only develop if the overall economics including government incentives render investment in the sector attractive to private investors. This study compares the profitability of three biofuel production types: grain based ethanol, cellulosic biochemical ethanol, and cellulosic thermochemical biofuels. In order to compare the current profitability of each of the production types, the Biofuels Comparison Model (BCM) was developed. The BCM is a spreadsheet model that estimates the net present value (NPV) for each production type given input and output prices, technical,... |

| Despite the significant rise in obesity in the U.S., economic research on obesity is still in its infancy. This paper employs a microeconomic approach to investigate the effects of price and income changes on weight in an effort to determine how a high-calorie food tax, a low-calorie food subsidy, and/or an income changes affect body weight. Although raising the price of high-calorie food typically will likely lead to decreased demand for such goods; it is not clear that such an outcome will actually reduce weight. The model developed in this paper identifies conditions under which price and income changes are mostly likely to actually result in a weight loss. The model is easily implemented using data on own-and cross-price elasticities that are often... |

| The federal government currently subsidizes ethanol with a fixed payment of $.51/gallon of ethanol blended with gasoline. Ethanol profitability is closely linked to the prices of corn and ethanol. The purpose of this paper was to develop a variable subsidy based on corn and ethanol prices and then to compare that variable subsidy with the fixed subsidy. This analysis proceeded in several distinct steps: First, we estimated ethanol profitability over a wide range of ethanol, corn, and distillers grains prices. This data was used in a regression analysis to estimate the ethanol profitability from the set of corn and ethanol prices. The regression coefficients became the basis for the variable subsidy. A version of the subsidy that used gasoline prices... |

| Ethanol, the common name for ethyl alcohol, is fuel grade alcohol that is predominately produced through the fermentation of simple carbohydrates by yeasts. In the United States, the carbohydrate feedstock most commonly used in the commercial production of ethanol is yellow dent corn (YDC). The use of ethanol in combustion engines emits less greenhouse gasses than its petroleum equivalent, and it is widely hoped that the increased substitution of petroleum by ethanol will reduce US dependence on imported oil and decrease greenhouse gas emissions. Production of ethanol within the United States is expected to double, from 3.4 billion gallons in 2004, to about seven billion gallons in the next five years. Two processes currently being utilized to... |

| Using the DM model is not complex: the user changes input values of interest (plant size,conversion rates, etc.) and examines the effect of these changes on output values (annual profits,feed stock requirements, etc.). There are nine worksheets in four modules in the excel workbook: assumptions, process, economics, and technology assessment. All user inputs are entered in the assumptions module of the model, which consists of three worksheets denoted with bright yellow tabs: process assumptions, economic assumptions and physical assumptions.The values that are entered on this page are then used in each of the subsequent modules to calculate hourly flow rates,equipment size and cost, total costs, loan terms, and annual profits. At the top of each page is a... |

| The economic and land use consequences of US biofuel programs and their contributions to GHG emissions have been the focal point of many debates and research studies in recent years. However, most of these studies focused on the land use emissions due to the first generation of biofuels such as corn ethanol, sugarcane ethanol, and biodiesel (e.g. [1, 2] [3, 4]). A quick literature review indicates that only a few attempts have been made to estimate these emissions for the second generation of biofuels which convert cellulosic materials into liquid fuels. Gurgel et al. [5] have used a highly aggregated computational model (CGE) to evaluate land use consequences of producing biofuels from biomass feedstock. This model does not distinguish between the first... |

| In this paper, we offer a general equilibrium analysis of the impacts of US and EU biofuel mandates for the global livestock sector. Our simulation boosts biofuel production in the US and EU from 2006 levels to mandated 2015 levels. We show that mandates will encourage crop production in both biofuel and non biofuel producing regions, while reducing livestock and livestock production in most regions of the world. The non-ruminant industry curtails its production more than other livestock industries. The numerical results suggest that the biofuel mandates reduce food production in most regions while they increase crude vegetable oils in almost all regions. Implementing biofuel mandates in the US and EU will increase croplands within the biofuel and... |
