| This work offers a new approach to the adoption of GM crop varieties by adopting the econometric methodology of the characteristics-based demand literature. A random utility framework was implemented through different specifications of a conditional (CL) and a mixed multinomial logit (MMNL) model of crop-variety choice. Willingness-to-pay and price elasticity estimates for traits were calculated. The MMNL approach demonstrates that individuals' tastes for some traits significantly vary across the population. Results further suggest that labor saving technologies have a much wider potential to be adopted. Overall, the use of a trait-based model to examine the adoption patterns of GM crop varieties among corn farmers in Minnesota and Wisconsin reveals a new... |

| This work uses unique data from three dairy dependent communities in rural Wisconsin to test established theory and empirical studies that link farm structure to local purchasing patterns and community economic development. A theoretical model of purchasing choices is developed to derive the determinants of local purchasing by dairy farms. This model is tested empirically using a double bounded Tobit model. The empirical estimations find little support for any linkage between farm size and local purchasing patterns across eleven major dairy farm inputs. The results do suggest that different community business characteristics (the supply side) and community attachment provide some explanations for diverse purchasing patterns. |

| Using farm data from three dairy-dependent communities in Wisconsin, this study addresses the question: Do small farms spend more locally than large farms? The work develops a theoretical model of farm cost functions with transaction costs varying between local and distant input sources. This model is then tested econometrically, describing farm costs and where they were spent as a function of transaction/search costs and farm characteristics. The results suggest that scale does matter to farm spending patterns. |

| This paper investigates the determinants of efficiency and technological progress at US research universities. It relies on a unique panel data set of multiple outputs and inputs from 92 universities covering the period 1981-1998. Over that time span, US universities experienced large increases in industry funding and in academic patenting activity. In this context, the directional distance function and a nonparametric representation of the underlying production technology are combined to obtain estimates of productivity growth and technical efficiency. A pooled-Tobit estimator is used to examine the determinants of technical efficiency and the rate of technological progress. The results show how changes in funding sources for U.S. research universities... |

| This work analyzes the effects of ethnic heterogeneity on credit and entrepreneurship in The Gambia. We develop a model of credit transactions based on ethnic density, which shows that where formal credit markets fail denser ethnic groups will have better access to credit. This work places a special emphasis on the Serahule ethnic group, which is ethnically dense and entrepreneurially successful. Our results show that Serahule-owned enterprises are indeed larger and more profitable. Furthermore, their marginal rate of return of capital is significantly lower than that of enterprises owned by other ethnicities, as one would expect with lower credit constraints. |

| The federated business structure exists in many sectors of the economy, but we know little about its comparative advantage. This paper explores theoretically and empirically the current dynamics of the federated cooperative system. Two hypotheses are tested: growth at the local co-op level has made the structure redundant and managerial incentives create disloyalty. We use a unique data set from a survey of local farm supply and grain marketing cooperatives in the Midwest. |

| This work has developed a theoretically consistent model of a farm household's choice between working on-farm and working off-farm and the effects of that choice on farm investment choices. The theory demonstrates the potential for wages driven by local economic conditions to be more important to dairy farm investment decisions than characteristics of dairy farms and farmers. The switching regression model developed from the theory is then tested with data from a representative sample of Wisconsin dairy farms. The econometric results demonstrate the importance of wages to farm investment decisions. |

| This document reviews the potential agricultural technologies that exist or can feasibly be produced to help promote poverty reduction and food security in Mali in the next 5 to 10 years. Overall there are a plethora of good technologies either available, in the pipeline, or feasible with a small amount of research effort. In many cases succeeding in poverty reduction and increasing food security will not be about choosing the exact right technology, but about helping farmers access and know about a panoply of available technologies from which they can choose the right one to maximize their future potential. |

| The life sciences have been the most dynamic area of US university research and commercialization efforts over the past twenty-five years. Using unique data from a large representative sample of life scientists this work examines whether academic patenting and commercialization complement, substitute for, or “hold-up” other research activities. The results highlight the resilience of the basic, federally-funded open scientific research model. Our findings, in turn, underscore the fundamental importance of maintaining the public funding and commitment to the academic, scientific enterprise. |

| This work investigates the presence and sources of economies of scope in R&D at U.S. research universities. The analysis evaluates the tradeoffs and synergies arising between traditional university research outputs (articles and doctorates) and academic patents. We propose a new measure of economies of scope based on a primal representation of the underlying technology. We derive a decomposition of economies of scope which identifies its sources (e.g., complementarity effects and scale effects). Non-parametric estimates of scope economies using R&D input and output data from 92 research universities show significant economies of scope between articles and patents, but modest complementarities. |
