The orthogonal group on the location-scale family is at the foundation of the stochastic structure underlying CAPM. Relaxing that assumption, we show how less restrictive matrix subgroup symmetries on the location-scale family of asset returns bound asset choices. Sign symmetry is a special case...

Inequalities are identified for subadditive (superadditive) functions of supermodular (submodular) functions. A simple adaptation yields inequalities for submultiplicative (supermultiplicative) compositions of log-supermodular (log-submodular) functions. Inequalities are also developed when the...

Information technologies used in production activities facilitate the acquisition of more detailed and more timely information concerning the state of the production environment. While the effects of distribution shifts on decisions under uncertainty have been much studied, less is known about...

Producers are subject to similar production risks, and so their outputs are likely correlated. Using the entire data-set rather than summary statistics, we study an ordinal definition of systematic risk. For risk-neutral producers in perfect competition, we trace the effects of an increase in...

The article develops a dynamic capital valuation model in which farms can act with farm-varying cost to increase the probability of avoiding an infectious endemic animal disease. Multiple endemic disease equilibria can exist, and the one with the largest set of action takers is socially optimal....

"Information Asymmetry as a Reason for Vertical Integration." In the Proceedings of the NE-165 Conference titled Strategy and Policy in the Food System: Emerging Issues, Washington, D.C., June 20-21, 1996

A closed-form dual representation of the multi-output production problem is developed under CARA and the large exponential family of multivariate price distributions. System-wide response analysis allows an understanding of second moment and risk tolerance effects, and provides insights on...

The feeder animal price is a derivative in the sense that its value depends upon the price of animals for the consumption market. It also depends upon the biological growth technology and feed costs. Daily maintenance costs are of particular interest to the husbander because they can be avoided...

Three trends that have been subject to recent discussion are a movement away from undifferentiated agricultural commodities toward more specialized products, reduced reliance on open markets for raw agricultural products, and a movement toward agricultural industrialization. Recent research...

Monotonicity of the likelihood ratio for conditioned densities is a common technical assumption in economic models. But we have found no empirical tests for its plausibility. This paper develops such a test based on the theory of order-restricted inference, which is robust with respect to the...
