SAMPLE 53 cattle farms in northwestern Minnesota adjacent to an area where bovine tuberculosis-infected cattle and deer were detected. PROCEDURES A semiquantitative deer-cattle interaction as...
Starting from the observation that an important next stage in exploiting the ocean energy is to install large arrays of several identical devices in order to raise their overall electricity production, the present work has as objective to assess the local and coastal impact of a large wave farm that would operate in the Portuguese coastal environment. The target area is the Portuguese maritime ...

Distribution of Gains from Research and Promotion in Multi-stage Production Systems: Further Results
In this study, we examine the distributional effects of research versus consumer promotion. A few years ago, a notable article by Wohlgenant (AJAE 75, 1993) investigated this issue and concluded that producers would benefit more from research on farm-level production than from research on marketing services and promotion. His findings have drawn important policy implications for the allocation ...
