The interconnections of agriculture and energy markets have increased through the rise in the new biofuel agribusinesses and the oil–ethanol–corn linkages. The question is whether these linkages have a causal structure by which oil prices affect commodity prices and through these links,...

In South Africa water law has recently changed, adopting the principle of water as an economic good,thus levying charges on its use. For small-scale irrigators this is an important change, becausecurrently their water use is entirely subsidized. In the coming years, subsidies will gradually...

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...

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...

Production costs for fresh Atlantic groundfish and scallop processing are examined using direct observation, linear regression analysis, and cost accounting. Assuming that management chooses a production technique where marginal costs are constant over a wide range of production due to...

In a recent paper, Clark and Munro (1980)showed that monopsony processing more than offsets the effects of open-access in the harvesting sector of a commercial fishery, and leads to overconservation of the resource. We show here that this conclusion depends critically on the cost of capacity and...

Dynamic adjustment is an integral part of natural resource economics. Commonly, capital is assumed to respond instantaneously to changes in profits, while in reality adjustment may take place only with a time lag. In this paper, an empirical analysis of capital (boat) dynamics in the North Sea...

The exclusion from U.S. waters since 1981 has greatly reduced the harvest potential for Canada's Pacific halibut fleet, making it particularly important that halibut resources in the Canadian zone he exploited at optimal levels. This paper provides a bioeconomic analysis of the joint-stock...

This paper examines the economics of catch discarding in fisheries. To study this issue a simple dynamic fisheries model is constructed. On the basis of this model it is demonstrated that in a differentiated fishery discarding of catch may be socially optimal. The paper goes on to show that...
