Modelling and Measuring Technical Efficiency: An Alternative Approach

In the literature, technical efficiency is measured as the ratio of observed output to potential output. Although there is no a priori theoretical reasoning, in the stochastic framework of measuring technical efficiency, the potential output is defined as a neutral shift from the observed output. The objective in this paper is to suggest a method to measure technical efficiency without having to consider the potential output as a neutral shift from the observed output

Causality between Technical and Allocative Efficiencies: An Empirical Testing

In production economics, one of the most interesting questions is that of the causal relationship between technical efficiency and allocative efficiency. This as yet remains a puzzle without a unique answer. There are a few theoretical analyses conceptualizing the relationship, but consensus has not yet been reached, and empirical tests are rare. Presents the empirical results of applying Granger’s (1969) and Sims’ (1972) causality tests using time series data on technical and allocative efficiencies of random samples of Indian farmers. These causality tests, with respect to technical and allocative effciences show that there is unidirectional causality from technical efficiency to allocative efficiency, and that the causative process is not bidirectional.Agriculture, India, Production management, Tests

Technology and farm performance: paths of productive efficiencies over time

The focus of this paper is the process of adjustment of farm performance to disequilibrium with new technology over time, which has been a subject of speculation till now. It shows that, left to learn from their own experience, farmers will be slow to realise the full technical potential of a new technology. Drawing on theories of intra-firm diffusion, the hypotheses tested in this paper using data from India are: (1) initial overall farm performances are characterised by modest and widely varying technical and allocative efficiencies, and (2) over time, average efficiencies rise. © 2001 Elsevier Science B.V.
