A method was developed with time series models to test hypotheses about the relationship between market structure and spatial price dynamics. Long-run dynamic multipliers measuring the magnitude of lagged adjustments for spatial milled rice prices were calculated from the time series model and...

Recently, there has been considerable interest in estimating food demand structure in China due to its huge market for food products. Previous literature has focused on the primary food products such as grains and meats, but studies on fruits and vegetables are limited. To fulfill this gap, this...

Growing farm size has generally been explained by technological advances that have allowed farmers to substitute capital for labor. Another possible factor in explaining recent farm size is the demographic shift: the age distribution of farmers has shifted to the right and older farmers...

This paper uses Data Envelopment Analysis to measure scale and technical efficiencies of 925 farms in rural Colombia and a Tobit model to identify the effects of land market characteristics on efficiency. Findings indicate that although larger farms are more scale efficient, they are not more...

This study uses revealed preferences of consumers to study the consumer valuations of rBST-free and organic milk. The study specifies and estimates a quadratic AIDS model for different milk types using US supermarket scanner data. The introduction of rBST-free and organic milk is used to...

The U.S. pork sector is evolving from an industry of small, independent firms vertically linked by spot markets to one of substantially larger firms vertically connected through contractual agreements and integration. Potential benefits to this tighter vertical arrangement include lower consumer...

Results of a nonlinear multi-commodity and multi-country spatial equilibrium model indicate that Chinese imports of whole soybeans, and to a less extent, processed soybeans will increase due to China's potential membership in the World Trade Organization. Further, U.S., Brazilian, and Argentine...

Using household survey data from seven provinces in China, this study provides estimates of the price responsiveness of feed demand by traditional and specialized household pork and poultry producers. Estimated elasticities are used to simulate the impacts of structural change in China's...

The analysis proposed in this paper is concerned with the welfare effects of self-regulation by Producer's Organizations (PO) as an alternative to market or public intervention. Using the advances of the economics of incentives, it studies the interaction of asymmetric information and the...

We use Monte Carlo experiments to assess the accuracy of two nonstructural and two statistical nonparametric market power tests. We implement these monopoly and monopsony market power tests using data from ten known market structures. The objective is to determine which test is most able to...
