Data for: Price equalization, trade flows, and barriers to trade

Abstract of associated article: In this paper we show that price equalization does not imply zero barriers to trade. There are many barrier combinations that deliver price equalization, but each combination implies a different volume of trade. We demonstrate this first theoretically in a simple two-country model and then quantitatively for the case of capital goods trade in a multi-country model. To be quantitatively consistent with the observed capital goods trade flows across countries, our model implies that trade barriers must be large, yet our model delivers capital goods prices that are similar across countries. The absence of barriers to trade in capital goods delivers price equalization in capital goods but cannot reproduce the observed trade flows.关联论文摘要：本文证明，价格均等化并不等同于贸易壁垒为零。存在多种可实现价格均等化的壁垒组合，但每种组合对应的贸易规模各不相同。我们首先通过简化的两国模型从理论层面验证了这一结论，随后在多国模型中针对资本品贸易场景开展量化分析。为使模型与各国观测到的资本品贸易流量实现量化匹配，我们的模型表明贸易壁垒需处于较高水平，但该模型仍能得出各国资本品价格相近的结论。若假设资本品贸易不存在壁垒，则可实现资本品价格均等化，但无法复现观测到的贸易流量。
