| In a period of market liberalization and multilateral trade negotiations, price discrimination for commodities with distinct markets provides additional policy options to support farm income. While both the USA and Canada have implemented price discrimination policies in their domestic dairy sector, so far the European Union (EU) has not. This paper evaluates the options of developing a price discrimination policy in the EU dairy sector. The analysis is based on an interregional model of the EU dairy sector, involving milk production, dairy processing, and consumption of ten dairy commodities in nine regions. The paper shows that a price discrimination policy that increases prices for commodities with more inelastic demand (fluid milk, soft dairy products)... |

| We develop a reduced-form model of price transmission in a vertical sector, allowing for refined asymetric, contemporaneous and lagged, own and cross price effects. The model is used to analyze wholesale-retail price dynamics in the US butter market. The analysis provides strong evidence of asymmetric price transmissions. It documents the complex nature of nonlinear price dynamics in a vertical sector and its implications for the distribution of future prices. It finds evidence that the asymmetric response to shocks is stronger in the sort run for retail prices, and in the longer run for wholesale prices. |

| This paper explores the implications of preference heterogeneity between wives and husbands in nonresource-pooling rural West African households for the effect of crop price changes on agricultural production, i.e., their supply response. A "semicooperative" game-theoretic model of household decisionmaking, in which household members make unilateral time and income allocation decisions and negotiate over who controls these resources, is proposed. The model is used to show that Pareto efficiency in both production and consumption do not hold. It is then employed to simulate the supply response to cotton price increases accompanying agricultural sector liberalization in Burkina Faso in the early 1980s. The simulated semi-cooperative model predicts the cotton... |

| Recently, financial assistance to farms has been widely under scrutiny. Agricultural assistance has an important impact on farmers' production decisions and those decisions in turn affect resources use or environmental quality. Surprisingly, the impact of agricultural policies on agro-biodiversity has been relatively neglected. This paper purports a novel framework to analyze the role of crop biodiversity on the mean and the variance of farm revenues. Further, the potential use of this framework in studying the impact of farm financial assistance to crop biodiversity loss is investigated. |

| This study presents an econometric analysis of the effects of a government price support program on price dynamics and price volatility. Price support programs, a common feature of agricultural policy, provide a lower-bound censoring of the distribution of market prices. An econometric model of market prices is developed using a dynamic Tobit specification under time-varying volatility. The model is applied to the U.S. non-fat dry milk market. It is used to investigate the impact of market liberalization on price dynamics and price volatility in the presence of private and public stocks. The econometric results show how the price support program and stocks (both private and public) affect expected price volatility. |

| 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. |

| The paper investigates the value of biodiversity as it relates to the productive value of services provided by an ecosystem. It analyzes how the value of an ecosystem can be "greater than the sum of its parts." First, it proposes a general measure of the value of biodiversity. Second, this measure is decomposed into four components, reflecting the role of complementarity, scale, convexity, and catalytic effects. This provides new information on the sources and determinants of biodiversity value. Third, the paper examines the role of uncertainty. In this context, the role of risk and of downside-risk exposure and their effects on the value of biodiversity are explored. This provides useful insights on how management and policy decisions can affect the value... |
