Using 11 years of experimental crop yields by cropping systems and fertilizer level, a MOTAD frontier was developed. This analysis allowed yield, cost, and stability interactions arising from crop sequences to be implicitly included. Target-MOTAD, Safety-First, and undominated stochastic...

A structural time series approach utilizing the state space model is used to analyze the impact of exchange rate volatility on the bilateral U.S. cotton exports to major export destinations. An EGARCH (Exponential Generalized Autoregressive Conditional Heteroskedasticity) model with normal and...

Several criteria that produce rankings of risk management alternatives are evaluated. The criteria considered are Value at Risk, the Sharpe ratio, the necessary condition for first degree stochastic dominance with a risk free asset, and the necessary condition for second degree stochastic...

A simple but new theoretical approach is used to analyse ex-ante the impact of tariff reduction. This methodology is based on the assumption of a constant price relation between each direct substitutable product. No elasticities are needed, but accurate import and domestic prices of the most...

This paper develops a model of how firms determine the quality of their output in a setting of asymmetric information. In this framework, the few lowest-cost firms produce high quality output and the rest produce at low quality due to a free-rider problem. The presence of imports exacerbates...

In this study a demand system analysis for beef in South Korea is constructed. A free trade demand system was used in which the economic welfare of market participants are maximized. Recognizing implicit discrimination about non-locally sourced beef products, this study deduces market demand...

Gravity models were developed to estimate the potential bilateral exports of cocoa under trade liberalization by the sixteen major cocoa producing countries to the US using panel data from 1989 to 2003. The results indicate that differences between resource endowment, relative size of economies,...

This paper illustrates the opportunities of incorporating more advanced functional forms into multi-country trade policy models. It suggests the use of flexible forms such as the Symmetric Generalized McFadden Function (SGMF) or the Normalized Quadratic-Quadratic Expenditure System (NQQES)....

In this paper a description is provided of the development and use of a target-MOTAD model for use in consultative work with farmers who are under financial pressure. The analysis of downside risk and introduction of a trade-off between financial and business risks are key features of this model...
