摘要：This paper examines relationship between price volatility and competition. A theoretic, vector autoregressions on farm prices of wheat and the retail prices of derivatives (flour, bread, pasta, bulgur and cookies) are compared to results from a dynamic, simultaneous-equations model with theory-based farm-to-retail linkages. Analytical results yield insights about numbers of firms and their impacts on demand- and supply-side multipliers, but the applications to Turkish time series (January 1988-December 1996) yield mixed results.
