Sound environmental regulation must achieve environmental objectives while maximizing economic efficiency. This paper evaluates the impact of regulation on efficiency by measuring annual productivity across regulatory regimes in two similar fisheries with differing policy expectations....

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 paper has a three fold contribution to the existing literature - 1) Indian state level sorghum input and output data for the period 1970-71 to 2000-01 is collected, 2) non-parametric linear programming productivity measures are estimated, and 3) examine the impact of policy variables like...

In assessing the productivity gains of a new technology, it is often difficult to determine the extent to which observed output gains are due to the technology itself, rather than to the skill of the farmer or the quality of the plot on which the new technology is tried. This problem of...

This study estimates nonparametric non-stochastic Malmquist indices and a stochastic Fourier production frontier to examine agricultural productivity and its interactions with socio-political institutions in 41 sub-Saharan African countries during 1961-1999. We have learned from this study that...

Econometric and simulation analyses indicate that land degradation does not threaten agricultural productivity growth and food security at the global level, but problems exist in some areas. Improving market performance could reduce erosion-induced yield losses to 0.1 percent per year and the...

A panel data of 27 provinces in China is used to analyze the productivity growth in China's agricultural sector over the period 1984-1999. We first compute the output-orientated Malmquist productivity indexes and its decompositions using non-parametric DEA (Data Envelopment Analysis) approach....

The tradeoff between short-term agricultural productivity and sustainability is examined with a statistical analysis of evidence from low input agriculture in Argentina. Estimation results show that more intensive land use, corporate leasing of land, and larger farm size are likely to increase...

This article examines technical efficiency of the Chinese grain sector using the framework of stochastic production frontier. The results reveal that: the marginal products of labor and fertilizer are much smaller than that of land; human capital and farm-level specialization have positive effect...

This research work uses stochastic frontier analysis (SFA) and data envelopment analysis (DEA) to examine the sources of agricultural productivity growth over time and of productivity differences among countries and regions in European Union over the period 1980-1998. A comparison of the mean...
