Abstract

This study is concerned with the productive efficiency among rice crops (Aus, Aman and Boro) and identifies the impact of climatic and environmental effects on rice production using a translog stochastic production frontier model in Bangladesh. The result shows that the translog production function fits the study better than the Cobb-Douglas production and there is a comprehensible impact on input variables of rice productive efficiency. The γ -estimate associated with the variance of the technical inefficiency effect is found large and significant (90%). The mean technical efficiency of the three types of rice during the period 1980 to 2008 is found to be 78, 71 and 80%, respectively. The loss of technical efficiency from the optimum level has occurred, because of lack of proper combination of related input variables. Among the inputs rainfall and good seed are recorded to be the most significant factor in rice production. The square effect of Area is found statistically significant with a negative value at 1% level of significance. The interaction effect of Area and Seed has been statistically significant. It is also observed that the interaction effect among the inputs and environmental factors exist in rice production. The explanatory variables are found decreasing the level of inefficiency and the climatic factors played the essence rule in rice productive efficiency in Bangladesh.
