| This article uses a general equilibrium framework and econometric analyses to examine economic wide impacts of the Conservation Reserves Program. It determines direct and indirect factors which affect the economic efficiency of the program and shows their magnitudes. It shows that the interaction between the program and the tax system causes indirect efficiency costs but the interaction between the program and the agricultural support subsidies generate economic gains. The program has the potential to distort the labor market and cause efficiency losses form this channel. However the analytical model shows that trade can reduce social costs of the policy because a part of the burden of the policy can be passed on to foreign consumers of crop products... |

| 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... |

| While traditional finance theory suggests that leasing and debt are substitutes, some papers demonstrated the theoretical possibility of complementarity. Empirical studies indicate that both are possible. In this paper we will use the Tobit model, ordinary least squares and quantile regression techniques to study the relationship between leasing and debt in farm capital structure in Illinois. Our results indicate that leasing and debt are close to perfect substitutes and leased assets are less risky than debt-financed assets in Illinois farms. The results from the quantile regression help us to capture the effects of farm characteristics on the distribution of leased to assets ratio. |

| In recent years there has been a flurry of activity aimed at evaluating the land use consequences of biofuels programs and the associated carbon releases. In this paper we argue that these studies have tended to underestimate the ensuing land use change, because they have ignored the role of irrigation, and associated constraints on cropland expansion. In this paper, we develop a new general equilibrium model which distinguishes irrigated and rainfed cropping industries at a global scale. Using the new model we evaluate the implications of land use change due to US ethanol programs, in the context of short run constraints on the expansion of irrigated cropland. Since irrigated area tends to offer a higher yield than its rainfed counterpart, this provides... |

| Much research has provided estimates of induced land use change and emissions for first generation biofuels. Relatively little has estimated land use change for the second generation cellulosic biofuels. In this paper we estimate induced land use change and emissions for these biofuels. Estimated emissions due to land use changes induced by biofuels production are uncertain not only because their associated land use changes are uncertain, but also because of uncertainty in the land use emissions factors (EFs). This paper also examines uncertainties related to these EFs and their assumptions. Three emissions factors including EFs obtained based on Woods Hole (WH) data, EFs developed by California Air Resources Board (CARB), and EFs obtained from the... |

| 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... |

| This paper uses stylized analytical and numerical general equilibrium models to evaluate the welfare impacts of alternative policies for reducing nitrogen run-off from agricultural production in an open economy while recognizing the presence of distortionary agricultural support subsidies and factor income taxes. The alternative policies examined here are a nitrogen run-off tax, a nitrogen run-off reduction subsidy, a tax on the production of agricultural goods, a "two-part" instrument - a combination of the second and the third policies, and land retirement. The paper uses an analytical model to express the welfare impacts of each policy into several components and compares these components across alternative policies. From the analytical model the paper... |
