Past research into determinants of international trade highlighted the importance of the basic spatial gravity model augmented by additional variables representing sources of friction. Studies modeled many sources of friction using various proxies, including indices based on expert judgment in some cases. This paper focuses on logistics friction and draws on a data set recently compiled by the World Bank with specific quantitative metrics of logistics performance in terms of time, cost, and variability in time. It finds that the new variables that relate directly to logistics performance have a statistically significant relationship with the level of bilateral trade. It also finds that a single logistics index can capture virtually all of the explanatory power of multiple logistics indicators. The findings should spur public and private agencies that have direct or indirect power over logistics performance to focus attention on reducing sources of friction so as to improve their countr

通过研究入国际贸易定列式突出了基本的空间重力模型的重要性由另外的可变物增添代表源泉的摩擦。研究塑造了许多源泉的摩擦使用各种各样的代理人, 包括索引根据专家的评断在某些情况下。本文集中于后勤学摩擦和画在数据集由世界银行最近编写以后勤学表现具体定量度规根据时间、费用, 和可变性及时。它发现直接地与后勤学表现关系的新可变物统计地重大与双边贸易有合作关系的水平。它并且发现一个唯一后勤学索引可能夺取实际上所有多后勤学显示的说明力量。研究结果应该激励有直接或间接力量结束后勤学表现集中注意于减少源泉的摩擦以便改进他们的国家的能力竞争在今天全球性经济的公开和私有代办处。而且, 因为后勤学度规直接地与操作的表现有关, 国家可能使用这度规瞄准行动改进后勤学和监测他们的进展。
