Do the EU countries import at the same price? The case of coffee
研究欧盟咖啡进口价格是否收敛，通过特征价格模型剔除质量差异后，发现成员国间价格仍显著不同，不支持市场一体化加深的假设。
Abstract The establishment of the Economic and Monetary Union was expected to determine price convergence in the market of the European Union, leading to the equilibrium theorized by the law of one price. This article investigates prices convergence in the coffee market among European importers. Coffee is not only a tradable and traded good, but also one of the most valuable traded commodities. We account for different qualities of coffee in a hedonic regression model, which isolate and remove the effects of factors that might affect price dispersion. Adjusted import prices result to be significantly different between European Member States, and do not support the hypothesis of a deepening European market integration.
