A positive mathematical programming model was constructed in this study to assess theeffect of three water pricing scenarios on Teboulba’s agricultural production systems.The effects of these scenarios were estimated for three groups of farmers from three irrigated districts. Results show that...

Fishery buy-back programmes reduce the availability to the industry of certain inputs used in the harvesting process, thereby increasing fishing costs and reducing the amount of effort applied to the fishery. The reduction in effort generates an economic benefit which must be weighed against the...

We present a conceptual, but empirically applicable, model for determining the optimal allocation of resources between exclusion and control activities for managing an invasive species with an uncertain discovery time. This model is used to investigate how to allocate limited resources between...

Recently there has been much concern regarding the use of forest resources in Australia. Proposals have been made to governments that would safeguard the forest environment but add to the costs of forest and logging industries. An analysis of the short-run effects of such proposals using the...

A major limitation to the effectiveness of benefit-cost analyses of proposals involving natural ecosystems is the assertion of existence demand. Not only has confusion arisen regarding its exact definition but little has been done to establish its magnitude. Existence benefits are defined and an...

Panel data are used in almost all subfields of the agricultural economics profession. Furthermore, many research areas have an important spatial dimension. This article discusses some of the recent contributions made in the evolving theoretical and empirical literature on spatialeconometric...

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...
