We overview the roles of production structure models in measuring fisheries’ productive performance to provide policy-relevant guidance for fishery managers and analysts. In particular, we summarize the literature on the representation and estimation of production structure models to construct...

This study investigates the optimal agricultural land use allocation and nitrogen application to arepresentative Japanese farm. The site-specific nature of numerous agri-environmental issues necessitates analysis ata disaggregated level in order to capture the underlying heterogeneity of...

This article tests the efficiency of the hog options market and assesses the impact of the 1996 contract redesign on efficiency. We find that the hog options market is efficient, but some options yielded excess returns during the live hogs period but not during the lean hogs period. Our findings...

This study examines the dynamic effects of grain prices and energy prices on catfish feed prices and the price of food-sized catfish at the farm level. Using the autoregressive distributed lag model and bounds testing procedure, a long-run relationship between feed and farm prices and their...

This report has four parts. The first part focuses on the changing environment in which the international wheat research system functions in developing countries. The authors describe recent trends in developing country wheat production against projected demand for wheat. Next, they present...

The measurement of productivity fluctuations has been the focus of decades-long interest. In addition to broad structural forces driving productivity changes, there is more recent interest in measuring and identifying the heterogeneous forces driving these changes. A major force is...

The Mekong Delta in Vietnam has become an important production area for pangasius. The importance of the sector in providing an income to many households means that it is relevant to study its economic production characteristics. In this article we use a stochastic cost frontier model to assess...

Market interactions between the common-property commercial fishery and (1) competitive aquaculturists and (2) a dominant-firm aquaculturist are modeled. It is found that the entry of a competitive aquaculturist increases natural fish stocks, reduces price, and increases total supply. If...

This paper considers the effects of granting a fishermen's sales organization exclusive rights to sell unprocessed fish. On the assumption that the fishermen's monopolyis able to discriminate between plants and end use alternatives in its pricing policy, the conditions for profit maximization...
