Relative Efficiency in Wheat Production in the Indian Punjab

摘要: In recent contributions to this Review, Lawrence Lau and Pan Yotopoulos (L-Y) applied the profit function concept analysis of relative efficiency Indian agriculture. They developed an operational model measure compare economic its components technical price (or allocative) for groups firms. By comparing actual functions small large farms at given output input prices fixed quantities land capital, they found that smaller had higher profits (total revenue minus total cost variable factors production, in case labor) than larger within range studied hence were economically more efficient. Further, able show superiority was due their since both tvpes Their results also indicate constant returns scale Both these findings have far-reaching implications optimal allocative structure paper, L-Y is confronted with new data wheat farms' Punjab. My run counter I do not find any differences efficiency) farms. Using model, performance old varieties Mexican varieties, tractoroperated non-tractor-operated The last mentioned two comparisons considerable relevance context "green revolution" absorption a rapidly growing labor force India other LDCs. Section present paper establishes link between my estimation procedure briefly describes variables. II provides empirical estimates, derives results, compares them those L-Y. III summarizes conclusions.
