We quantify the emergence of biofuel markets and its impact on U.S. and world agriculturefor the coming decade using the multi-market, multi-commodity international FAPRI (Food andAgricultural Policy Research Institute) model. The model incorporates the trade-offs betweenbiofuel, feed, and food...

We describe a simulation-based algorithm for Bayesian estimation of structuraleffects in models where the outcome of interest and an endogenous treatment variableare ordered. Our algorithm makes use of a reparameterization, suggested by Nandramand Chen (1996) and Li and Tobias (2005) in the...

This paper examines the impact of public and private agricultural research andextension on agricultural total factor productivity at the state level. We test the hypothesis thatthe composition of agricultural experiment station funding—share of funding from impact offederal competitive grants...

This paper presents new econometric evidence on state government’s demand for resources to support local agricultural experiment station research. The econometric model consists of a complete-demand system covering four major resource sources, and it is fitted to annual observations on 48...

Genetically modified (GM) foods have caused many controversies. One important controversy relates to tolerance?the impurity rate that is tolerated before a commodity must be labeled as genetically modified. Currently, the United States does not have a specific tolerance or threshold level for GM...

Public debate continues over whether the United States should regulate genetically modified (GM) foods by imposing a mandatory labeling policy. This paper develops a model that shows that a voluntary GM-labeling policy results in higher welfare than a regulated mandatory GM-labeling policy, if...

We propose a novel approach to measuring the causal effect of family structureon a child’s outcomes. In a war, some fathers are killed in action and cannotreturn to their families. This creates a natural experiment in which the effectsof a father’s absence can be tested. Using data from the...
