| Authors: | J. Barallat, E.W. McLaughlin, D.R. Lee |
| Abstract:
The farm-retail price spread, or marketing margin, has remained an important and sometimes controversial focus of agricultural economics research. Previous research on marketing margins is reviewed. Research comparing the performance of alternative models of marketing margin behavior with application to the Spanish fresh potato market is summarized. Six alternative models are specified and compared: an econometric model; a univariate ARIMA model; a multivariate time-series model; a composite model; and two "naive" trend-based models. The forecasting abilities of the six models are also compared. The implications of the results for both private firm strategies and public policy are discussed. | |
