Abstract: This study focuses on comparing the technical efficiency of rice farms in two locations with different level of urbanization. A production function using maximum likelihood method is estimated and efficiency score of individual household is calculated using stochastic frontier analysis. The efficiency scores are regressed on variables including farm-household characteristics and degree of output market commercialization. The empirical evidence suggests that the elasticity of production to land size and biological inputs like chemical fertilizer, pesticide, fungicide and seed is positive and statistically significant. The average efficiency scores in two sample districts indicate that the production can be increased by 26-33% through improving efficiency in a given technological condition. The result suggests that the degree of commercialization has positive effect on technical efficiency . Furthermore, household characteristics like education, age, share o...

Sources of Agricultural Productivity in Low and Lower Middle Income Countries Sujan PIYA 1) and Akira KIMINAMI 2) 1) Corresponding Author, Graduate School of Agricultural and Life Sciences, The University of Tokyo 2) Professor, Graduate School of Agricultural and Life Sciences, The University of Tokyo (Received February 18, 2010) (Accepted December 5, 2010) Abstract Assessing and quantifying the sources of agricultural productivity across developing countries is the prime objective of this paper. Thirty-one low and lower middle income countries from the Asian and African continents were selected for the study. The results show that variations in land productivity are well explained by variations in labor and fertilizer resources. However, variations in tractor and livestock inputs have low impacts on the performance of land productivity. The average annual malmquist factor productivity index is positive. Factor productivit...

1. Evaluating the impact of geographic concentration on Nepalese agricultural export http://sae.sagepub.com/content/11/2/207.abstract Abstract: This study observed and analyzed the behaviour of Nepalese agricultural export using vector error correction model (VECM). The first part of the analysis focused on the dynamic relationship among agricultural export, geographic concentration and total agricultural production. Results of the study revealed that Nepalese agricultural export was very much dependent on the Indian markets and had positive relation with the geographic concentration index in the long run. The significant and higher error correction term indicated that the short-run fluctuations in geographic concentration and agricultural production were promptly adjusted to its long-run trend. The long-run effect of agricultural production increment on export was pos...
