Further Evidence on Competition in the US Grain Export Trade
研究了美国小麦和玉米出口市场结构对出口企业定价行为的影响，发现市场集中度等因素与歧视性定价相关，但市场力量对价格加成的影响较小。
This study analyzes the relationship between export market structure and the pricing behavior of U.S. grain exporting firms. A generalized Cournot model is estimated by two-stage least squares using pooled data sets for U.S. wheat and corn exports. The cross-sectional units correspond to foreign country destinations. Discriminatory export pricing behavior was found to be significantly related to export seller concentration, U.S. market share, total export volume, and import market size. Yet, the estimated coefficients linking these market structure variables to the export price markup were relatively small in magnitude, suggesting little quantitative impact from market power.
