    The objective of this paper is to investigate the dynamics of the slaughter weight of Japanese beef cattle. We extend the theory of and provide empirical results for the dynamics of slaughter weight. Our theoretical analysis shows that optimal slaughter weight increases with an increase in the price of either feeder calves or the flow output while it decreases with an increase in either feed price or interest rate. Slaughter weight response to beef price depends on the sex of the animal. An increase in beef price is found to reduce slaughter weight of steers (male animals with no flow output); however, the result for slaughter weight of female animals is ambiguous. Our time series analysis for the Japanese beef sector (1975-1999) finds evidence of long-run relationships between the average slaughter weight and prices (except for interest rate), consistent with theoretical response patterns. However, the empirical results indicate that no specific relationships exist between the average beef slaughter weight and prices in the short-run.

    In this paper an empirical evaluation of the performance of Sri Lanka's agricultural sector under policy reforms with respect to the exchange rate implications is made. By the policy reforms, the exchange rate reforms made considerable impact on the agriculture exports, input and food imports and economic development. In our general equilibrium growth accounting approach, the real contributions of agricultural exports, food imports and fertilizer price reveal that without the exchange rate reform the contributions would have been really detrimental to the agricultural production as well as to the economy of Sri Lanka. In this way, Sri Lanka's policy reform had a positive effect on the economy through the exchange rate reform, although it had negative impact on the domestic food production sector and related small farmers. Further analysis on the contributions of technical changes in agriculture and non-agriculture supports the push-pull effect concept in both sectors in this paper.
