Environmental policies generally address problems associated with ill-defined property rights. Our framework describes property rights "regimes" as functions of the degree of consolidation of rights to an asset and of the parties holding those rights. Efficient resource use occurs if welfare...

Using data on the distributions of disease and pest resistance among wheat varieties, this paper reports theoretical and empirical findings concerning the efficient management of a gene bank and the optimal size of a collection.

This paper argues that the subjective expected utility (SEU) hypothesis has serious limitations in both positive and normative analysis. In addition to experimental evidence, we discuss examples where alternatives to the SEU model provide a richer framework for the study problems of choice under...

This article is the further development and refinement of quarterly models of U.S. field crops, drawing upon the theory of pricing, production, and storage under uncertainty. The decisions of storage industry and farm production are taken into account. The findings of this research are both...

Resource endowments, modeled as quality indices, are placed into a dynamic production model to determine resource use adjustments to meet sustainability and production input usage changes when resource quality fluctuates. Impacts of sustainability are identified and the time path of resource...

The household production approach is used to characterize the household's preference toward nutrients in food consumption. Elasticities of substitution and Hicksian price elasticities are estimated, price- and expenditure-nutrient elasticities are calculated. Results show that protein is the...

Monthly price data from the Philippines are used to test the influence of government buffer-stock programs on the level and variability of rice prices from 1974-1990. Results do not support the conjecture that prices were correlated with stock purchases.

This paper examines co-management of a spiny lobster fishery located in Punta Allen, Quintana Roo, Mexico. Decision trees are used to analyze voluntary compliance behavior by fishers. Results indicate that legitimacy with respect to the process and the outcome of the rules lead to perceptions of...

An econometric model of the U.S. corn sector is used to estimate the welfare effects of the Uruguay Round Agreement. Trade liberalization also leads to changes in input use that can affect the environment. The gains from trade liberalization are adjusted for the environmental effects caused by...

Two taxation schemes were designed to be included in a multi-regional multi-sectoral General Equilibrium model for reducing the use of commercial fertilizers, with the goal of alleviating surface water pollution. Under the 500% tax rate, results showed that 0.1% of the national income was given...
