The study estimates the determinants of technical inefficiency among the farmers that are participating in the Ondo State chapter of the National Directorate of Employment program in Nigeria. Using a tobit analysis, it was found that extension visits, higher education, land input and membership...

This paper computes overall efficiency for 64 farmers practicing multi-cropping system in Ekiti State of Nigeria. These are decomposed into pure technical efficiency and scale efficiency. Results show that 34 and 40 farmers are technically and scale inefficient, respectively. Overall, 40 farmers...

This paper estimates and compares generalized Box-Cox and composite cost functions to identify scale and scope economies. The robustness of the outcomes to different functional specifications was examined. Increasing returns to scale was common for product-specific and the overall measures....

This paper computes Malmquist agricultural productivity indexes for 125 countries over the period 1961-2001. These are decomposed into efficiency change (i.e., pure technical efficiency and scale efficiency changes) and technical change (i.e., input bias and magnitude components). Results show...

This study investigates consumer demand for meat products in Nigeria and tests if any of the meat products are separable from one another. Estimating a generalized nested demand system, the Rotterdam model was selected using an adjusted likelihood ratio test. Results indicate that mutton and...

This study's objectives were to determine factors influencing smallholder farmers' adoption of a stall-feeding management system for improved dairy cattle in semiarid Tanzania and other related technology packages. Heckman's two-stage procedure was used to determine factors influencing...

On-farm research (OFR) has increased in popularity in the U.S. in recent years due to heightened interest in sustainability issues, the likely decline in resources available for agricultural research, and increasing pressures for accountability and responsiveness to state and local needs....

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...
