Book Description
This thesis offers a unified framework to analyze both short- and long-run trade dynamics in a consistent manner. It explains "the international elasticity puzzle", a low trade elasticity against temporary shocks and a high trade elasticity against permanent shocks, studied in Ruhl (2008). The model in this paper extends the idea of export sunk costs and uncertainty to more general productivity shock processes by embedding the classical theory of "export hysteresis" into a continuous-time trade model with heterogeneous firms, and considers the effects of both aggregate and idiosyncratic productivity shocks. A sharp analytical characterization of the equilibrium elucidates the microfoundations of trade dynamics linking a static trade model with heterogeneous firms and an international macroeconomic model. Due to the sunk costs and uncertainty, firms do not change their export status against small temporary shocks. Aggregate productivity shocks and export sunk costs explain the elasticity puzzle because of the different adjustments on the extensive margin. If the productivity shocks are idiosyncratic, the economy is in a steady state, with individual firms moving around within a stationary distribution of productivities. Export hysteresis gives rise to a region of firm productivity where both exporters and non-exporters coexist given the same current productivity. The full model incorporates both types of shocks and offers realistic microfoundations of trade dynamics including simultaneous export entry and exit, an evolving productivity density of exporters, and the sluggish trade response to aggregate shocks. The model can be applied to various other settings where both aggregate and idiosyncratic shocks affect heterogeneous agents' dynamic problems.

Book Description
Renowned trade theorist Koji Shimomura passed away in February 2007 at the age of 54. He published nearly 100 articles in international academic journals. The loss of this extremely productive economist has been an enormous shock to the economic profession. This volume has emerged from the great desire on the part of the profession to honor his contributions to economic research. Contributors include authoritative figures in trade theory such as Murray Kemp, Ronald Jones, Henry Wan, and Wilfred Ethier, world-renowned macroeconomists such as Stephen Turnovski and Costas Azariadis, and leading Japanese economists such as Kazuo Nishimura, Makoto Yano, Ryuzo Sato, and Koichi Hamada. This broad range of contributors reflects Koji Shimomura’s many connections as well as the respect he earned in the economic profession. This volume offers the reader a rare opportunity to learn the views of so many renowned economists from different schools of thought.

Book Description
This dissertation consists on three essays on international trade and industry dynamics. All three essays study empirical applications of open economy environments with heterogeneous firms who make decisions over time.The first essay studies trade policy and the dynamics of the solar photovoltaic manufacturing industry in the U.S. In it I develop a computable, continuous-time dynamic model of the industry where domestic firms engage in price competition against each other and an importing sector to sell solar panels to domestic consumers. Firms can attain cost reductions through learning by doing and R&D investments. I use the model to estimate its main parameters using firm-level survey data from the Department of Energy and then simulate the application of countervailing duties to imports of solar panels, analyzing the implications for the evolution of the industry and welfare. In a scenario where a 30% duty is applied to imports, domestic firms respond by increasing R&D expenditures, therefore increasing productivity and setting lower prices, even when concentration increases as high productivity domestic firms gain market share.The second essay is on the dynamics of the textiles and garments industry in Bangladesh. First, it shows that, in contrast to the standard description of entry into foreign markets, Bangladeshi exporters are fully committed to foreign markets, exporting most of their output abroad; they start big, not small, and show high survival rates once they start exporting. They are born to export firms who operate in orphan industries, with essentially missing domestic demand for their products. In addition to the usual fixed and sunk costs of exporting, they must face presumably higher costs of starting up new businesses. Then it compares these patterns with those of China, Colombia and Taiwan, and find similar but less-striking patterns for China. These features seem to be missing in Taiwan and Colombia, which accord with other typical cases described in the literature. Finally, it adapts a search and learning model of export dynamics to show how the presence of high sunk costs of establishing a new business and the absence of a domestic market can generate export trajectories similar to the ones we observe in Bangladesh. The third essay focuses on the links between productivity and exporting. The trade literature has identified three relationships. First, that productivity causes exporting, so that there is selection into exporting by more productive firms. Second, that exporting generates productivity growth through, for example, learning-by-exporting. Third, that firms make choices that make them more productive in preparation to export. The essay shows that patterns of Chinese exporters are consistent with all three hypotheses. Exporters are more productive than non-exporters, which is consistent with selection. For successful exporters, most of the productivity growth during the period occurred after entering export markets, rather than before. For unsuccessful exporters, on the other hand, this pattern is reversed. Average annual productivity growth, however, is higher prior to entry for both groups. Finally, new exporters increase sales expenditures and earn higher revenue from new products than other firms before they start exporting. This is true when compared to both non-exporters and continuous exporters.

Book Description
The second essay incorporates endogenous factor-proportions trade into an inter-national business cycle setting and demonstrates that the integrated framework substantially improves upon past, standard models that assume exogenously-determined structures of trade in matching key moments of the international business cycle data, resolving the "anomalies" that arise in the standard framework. An additional implication is that the type of trade rather than overall trade between countries matters: countries trading goods that are similar in factor intensity (intraindustry trade) tend to exhibit negative investment comovement while countries whose trade is characterized by more disparate factor content tend to exhibit greater investment comovement. The third essay, on a portfolio perspective of international capital flows, analyzes a useful accounting framework that breaks down the current account to two components: a portfolio reallocation effect and a portfolio growth effect. Past empirical evidence strongly supporting the growth-effect as the main driver of current account dynamics is misconceived. Its remarkable empirical success is driven by the dominance of the cross-sectional variation, which, under conditions met by the data, is generated by an accounting approximation. Finally, this chapter shows that the portfolio reallocation effect is the quantitatively dominant driving force of current account dynamics in the past data.

Book Description
This book presents a representative collection of papers on international trade, one of the most dynamic sub-fields in economics. The contributions range over all the major areas of research, including articles on the geographical aspects of international trade by Paul Krugman and Alan Deardorff, on dynamic stochastic economies by Avinash Dixit, and on endogenous growth by Gene Grossman and Elhanan Helpman. In addition to the theoretical contributions, the book also contains work on important policy issues such as auction quotas, discussed by Kala Krishna, and the role of government in economic development, by Anne Krueger. Also included is an assessment by Bill Ethier of the theoretical achievements of a leading authority in international trade theory, Ronald Jones, in whose honour the essays were written.

Book Description
This volume contains papers on Economic Theory and International Trade: The papers on Economic Theory cover the existence and structure of competitive equilibrium in various settings: non-convexities, non-transitivity of preferences, and absence of differentiability or free-disposal assumptions, the role of the compensating variation as a welfare measure, oligopoly under bounded rationality, and regulation of a public utility. The papers on International Trade offer analyses of the "Dutch disease" or the Atlantic Slave Trade, or treat the influence of economic growth on import demand, the terms of trade, and other economic variables, as well as theoretical and empirical evidence for the validity of the Heckscher-Ohlin model. The papers, rigorous and often requiring mathematical sophistication, variously reflect Trout Rader's work.
