Book Description

My graduate research has been organized around two main themes: (i) the causes and consequences of trade integration and (ii) the strategic nature of armed conflict. The expansion of international trade over the past sixty years has played a major role is determining the fates of nations, both for better and for worse, and likewise has the potential to shape our futures in ways we need to be able to anticipate. Similarly, the death, destruction, and diversion of productive resources associated with violent conflict continue to present a critical obstacle to shared prosperity. The papers I am presenting as the chapters of my dissertation are representative of the contributions I am interested in making in these important research areas. My research on trade integration spans both the micro-level of what forms trade integration may take as well as higher level concerns about how freer trade will affect both the world economy as well as the individual economies within it. Two chapters of my dissertation, "Beyond Tariffs: Quantifying Heterogeneity in the Effects of Free Trade Agreements" and "Finding the Influence of Communication on Trade" are devoted to this subject. In "Beyond Tariffs", for example, I show, using NAFTA as an empirical case study, that the effects of free trade agreements on individual nations may not be what we might expect to observe ex ante based on tariffs. Relying solely on tariffs to project NAFTA's effects not only greatly underestimates the overall welfare increases for all three NAFTA countries--Mexico's in particular--but also overstates the positive effects of NAFTA on U.S. producer prices. It follows that "heterogeneity" in the effects of free trade agreements, both within and across agreements, may not be well-understood. In "Finding the Influence of Communication", I investigate whether the sharing of a common language promotes trade in a way similar to trade policy and, if so, what the consequences of increased language learning will be for global trade. Most notably, I find the effect of communication in native languages on trade tends to be underestimated in the absence of controls for communication in non-native languages. Surprisingly, while I find strong evidence for the causal impact of foreign language acquisition on manufacturing trade, I do not find similarly strong evidence for services trade. I also find that, unsurprisingly, adding to the world's population of English speakers has by far the largest impact on trade of any major world language. Interestingly, however, when I remove all non-language barriers to trade, I find the forces of geography and history may have greatly impeded the relative appeal of Chinese as a competing global language. The third chapter of my dissertation, "The Problem of Peace: A Story of Corruption, Destruction, and Rebellion", joint with Constantinos Syropoulos, deals with a different kind of question: what are the economic incentives that drive the emergence of destructive conflicts, and of intra-state conflicts ("civil conflicts") in particular? Specifically, we investigate how the central presence of state (fiscal) institutions in civil conflicts generates unique explanations for the emergence of conflict itself. International trade plays an important role in this chapter as well, but mainly as a backdrop for illustrating the unique trade-offs between "peace" and "welfare" that may arise in this context. It is possible for changes in international prices to move in favor of promoting settlements, but such settlements can be associated with (socially wasteful) increases in arming and/or taxation. We also explore, among other things, how limiting the government's fiscal capacity may tilt the balance towards peaceful settlement.
