In this paper we develop an autoregressive spatial simultaneous equations model to investigate the county-level determinants of small business growth and median household income in Appalachia during the period 1990-2000. Our GS2SLS and GS3SLS estimation results indicate significant spatial...

Immigration reform may significantly impact the specialty crops sector since more than half of the workforce is foreign-born and undocumented. Based on data from the National Agricultural Workers Survey, the trends pertaining to workers' legal status, employment and wage rates in the U.S. and...

This study aims at examining the relationship between macroeconomic and policy variables and food stamp program participation in West Virginia. Static and dynamic econometric models are employed. Results indicate that macroeconomic conditions significantly explain food stamp program...

A three-step estimation method and a Nonlinear Quadratic Almost Ideal Demand System (NQAIDS) are used to assess the vegetable demand behavior of rural and urban households in the Philippines. The results show that most of the expenditure and own-price elasticities of the vegetables analyzed are...

We introduce a modeling framework called Transaction Cost Economics to help decision makers in rural health care markets choose among alternative organizational relationships in order to more cost-effectively deliver healthcare services. In particular, the hospital-physician relationship is...

For countries that could not benefit from the Green Revolution due to heterogeneous and unfavorable biophysical environments, agricultural biotechnology potentially provides a means of improving the quality and quantity of agricultural production. This paper analyses some of the major issues...

Using National Agricultural Workers Survey data, we estimate U.S. farm worker wage differentials by legal status. In order to adequately correct sample selection bias, we develop a Heckman-type two-stage method with an ordered probit model in the first stage and a wage equation model in the...

This paper uses two different techniques to measure efficiency in a panel of two hundred multi-product Kansas farms from the period 1984 to 2004. The non-parametric linear programming technique, Data Envelopment Analysis (DEA); and a parametric stochastic frontier approach, a translog production...
