| 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. |

| GM corn seed companies have innovated continuously with the introduction of new traits and, more recently, with the creation of stacked varieties, which combine more than one trait. This work develops a Bayesian model of adoption dynamics that demonstrates how uncertainty with a package technology with known risk can lead to a sequential adoption pattern in which farmers adopt a single component first. We then develop a semiparametric panel data model of adoption dynamics to measure the effects of experience with single trait (non-stacked) varieties on the adoption of stacked varieties. The results underscore the importance of early experience with the non-stacked technology in the subsequent adoption of stacked varieties, i.e., a sequential adoption... |

| 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. |

| A key piece in understanding the link between the extension and research missions of Land Grant universities is to understand the role of faculty with (and without) extension appointments within agricultural colleges. This article provides a comparative empirical portrayal of the primary activities of agricultural college faculty, and demonstrates the basic vitality of extension professors within the Land Grant system. Professors with smaller extension appointments are heavily engaged in the major research efforts of their universities at even greater levels of production than professors without extension responsibilities. Professors with heavy levels of extension appointments experience increasing tradeoffs between core extension activities and research... |

| 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. |

| 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 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. |

| This work exploits information on U.S. patents to identify trends in university ag-biotech patenting and citation performance. It sets forth some key issues concerning patterns of university ag-biotech patenting and then provides an empirical analysis on the evolving trends. Land Grant Universities account for most U.S. agbiotech patents. The data show a path dependent innovation pattern, in which there also seems to be a culture of patenting that develops at certain universities. Evidence shows that ag-biotech patents are more cited than the average university patent. Inequalities across Land Grant Universities are also evident in the production of agbiotech patents, although perhaps not to a much greater degree than underlying inequalities in funding and... |

| 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 paper investigates the presence and sources of economies of scope in R&D production at U.S. research universities. The analysis evaluates the tradeoffs or synergies arising between traditional university research outputs (articles and doctorates) and a more recent and burgeoning output: academic patents. Using a shortage function, we propose a decomposition of economies of scope (decomposition which includes complementarity effects and scale effects). R&D input and output data from 92 public and private research universities are used to obtain non-parametric estimates of scope economies. The results show significant variations in economies of scope and sources by size and type of university. |
