A programming problem is introduced which calculates efficiency scores for two jointly produced products. These scores, as well as Malmquist total factor productivity indices, were calculated and reported for both the crop and livestock sectors for 27 countries. Our two-score method allows us to...

It is widely recognized that purchases of perishable agricultural products are affected by the seasonal cycles of production. When there are seasonal effects where seasonal buying is not explained by prices alone, the seasonal component can be captured using appropriate dummy variables in a...

This article demonstrates that both crop area and output elasticities can be calculated from a profit function. A Chambers/Just profit function (which includes land allocations as quasi-fixed factors) is used to derive shadow price equations for each crop area allocation. Jointly solving these...

What has been ignored in much of the existing studies of oligopoly power is that market behaviour need not be static in nature, and oligopoly power in agriculture need not be present in every month of the year. In a market which is characterized by seasonality and supplied by different sources...

A retail demand model measured the impact of the Food and Drug Administration's 2006 announcement warning consumers about E. coli O157: H7 contamination in spinach. Model results indicated that bulk lettuces were shock substitutes (in contrast to price substitutes) as consumers purchased...

This article demonstrates that both crop area and output elasticities can be calculated from a profit function. A Chambers/Just profit function (which includes land allocations as quasi-fixed factors) is used to derive shadow price equations for each crop area allocation. Jointly solving these...

A new approach for estimating oligopoly power coefficients is proposed. The methodology used sidesteps the difficulties of obtaining cost data and obtaining coefficients which do not satisfy the theoretical properties of the cost function.
