报告摘要:

The empirical evidence is controversial on whether a reduction in the search cost mit- igates the deterrent role of physical distance on international trade. In this paper, we develop a trade model with sequential consumer search to explore the effect of a reduction in search cost on the distance elasticity. We show that a reduction in the search cost may increase or decrease the distance elasticity depending on whether the consumer’s preference is log-concave or log-convex distributed. Then we exploit the roll-out of the “broadband China pilot” over Chinese cities as a quasi-experiment of search cost reductions and examine its implications for the distance elasticity. Overall, we find an increase in distance elasticity following the reductions in search cost. How- ever, the distance elasticity becomes smaller when the consumers’ income is closer to the Pareto distribution, consistent with the theoretical prediction.
