Description: International economists study phenomena that are most meaningfully defined and relevant at the country or cross-country level. Key issues include the response to exchange rate or other macroeconomic shocks, cross-country differences in productivity and growth, and the impact of policy on bilateral trade flows. Naturally, these subjects have typically been examined with highly aggregated data. The three chapters of this dissertation correspond to these three issues, but offer analyses of novel datasets that are significantly less aggregated. The results generate new findings, clarify existing literatures, and overturn conventional wisdom on each of these three topics in international economics. The first chapter starts with the observation that forty percent of all U.S. imports occurs between related parties, such as trades between two subsidiaries of the same multinational company. The chapter uses a dataset that identifies intrafirm trades to demonstrate differences in price spell duration, the synchronization of price changes, and the price impact of exchange rate shocks. Most of these patterns emerge in model in which vertically integrated exporters, unlike arm's length exporters, maximize combined manufacturer and distributor profits.

The second chapter discusses Asia's newly industrialized economies, which are the world's fastest growing since 1960. The chapter reconciles seemingly contradictory explanations for their rapid growth, and for the role of international trade and investment. For example, in Singapore, "favored" firms earned large economic profits and received preferential tax treatment, subsidies, and access to capital. These factors allow measured user costs to be constant despite declining returns to capital. The chapter provides sector level empirical evidence of profits and heterogeneous user costs, derives measures of technology growth that correct for these imperfections, and discusses the implications for Asian development. The third chapter examines the claim that post-9/11 changes in visa policies caused the sharp decline in travel to the United States following the attacks. This chapter estimates an empirical model which distinguishes the impact of visa policy from economic and country-specific factors and demonstrates that changes in visa policy were not important contributors to the decline. Rather, the reduction was largest among travelers who were not required to obtain a visa.
