Book Description
This dissertation's three essays investigate trade and productivity effects on firm behavior based on new heterogeneous-firms trade models in the case of Korea. In the first essay, firms' decision to export in the case of Korean manufacturing industries is examined, where the change in firms' productivity before and after exports are analyzed. In particular, two common hypotheses of export decision - self-selection and learning-by-exporting- are tested using a dynamic model of firm export behavior and a Korean firm-level panel database. Evidence of self-selection is found in only three out of eight industries, but that of learning-by-exporting is limited. Sunk-cost or previous-export-experience effect on the predicted export probability is relatively larger than that of firms' productivity and size. The second essay investigates the effect of trade cost changes on firms' entry and exit in Korean manufacturing. Empirical support is found for new trade theories' predictions on firm entry and exit, and the number of exporting firms, and changes in market share following trade-cost changes. However, Korean manufacturing appears to differ from some of the outcomes of the heterogeneous-firms theory, especially in the result that large firms are less likely to be a new exporter. Rather, smaller and less capital-intensive firms tended to enter the export market. In general, the results of this essay show that changing trade costs had important consequences for the structure of manufacturing activity in Korea. In the final essay, the differences in the scale economies of exporters and non-exporters in Korean manufacturing are investigated. Results from estimating a production function show that exporters face diseconomies of scale in four of five industries. A matching technique confirms the difference in returns to scale between exporters and non-exporters. The evidence that size and hence, scale economies may be less important for trade participation and gains from overseas market, bodes well for small or medium exporters. In summary, this dissertation has improved the understanding of the relationships among trade, productivity and firm behavior. The key determinant of firms' export behavior in the Korean context appears to be previous experience in overseas markets. Not surprisingly, the Korean government has invested heavily in lowering their firms' cost of accessing foreign markets. In industries where Korea has a comparative advantage, high productivity of firms appears to promote trade participation. However, productivity growth in other industries is low and falling, in some cases. A balanced approach to investments in productivity and export promotion would sustain and improve Korean manufacturing's competitiveness in global markets.

Book Description
In recent years, globalization and the expansion of information technologies have reshaped managerial practices, forcing multinational firms to adjust business practices to different environments and domestic companies to adjust to their foreign competitors. In International Differences in the Business Practices and Productivity of Firms, a distinguished group of contributors examines the phenomenon of widespread differences in managerial practices across firms, establishments within firms, and countries. This volume brings together eight studies that combine qualitative and quantitative insider analysis of business practices such as the use of teams, incentive pay, lean manufacturing, and quality control, revealing the elements that determine which practices are adopted and why. International Differences in the Business Practices and Productivity of Firms offers a much-needed model for measuring the productivity and performance of international firms in a fast-paced global economy.

Book Description
This dissertation discusses the role firms behavior takes in shaping our understanding of international trade. It discusses the impact on well held theoretical and empirical results from international trade when accounting for commonalities in firm behavior that distort the economy. Chapter 1 develops a model of international trade where firms are heterogeneous across two dimensions: capacity and productivity. Capacity constraints rationalize empirical results that are anomalous to new trade theory. When capacity is relatively abundant, the model predicts stronger competition (selection) in larger markets. Con- versely, when capacity is relatively "tight" constrained firms weaken competition and boost the average price level in larger markets - similar to tacit collusion. Under inter- national trade, constrained firms choose to sell a greater fraction of their production in the largest accessible market. Capacity constraints can thus magnify (dampen) domestic price and competition distortions when foreign markets are relatively large (small). Chapter 2 addresses biases in estimates of the impact of product variety on prices and welfare when market structure is inaccurately defined. We employ a market- based data set on the U.S. automobile market that allows us to define goods varieties at a more precise level, as well as discern location of production and ownership of varieties. Our estimates of price and welfare changes from new varieties in the U.S. automobile sector are twice as large as standard estimates when using our detailed market-based data. We also show that new varieties introduced by foreign-owned affiliates provided an additional 70% welfare gain during our sample. Chapter 3 notes that estimates of consumer gains from imported products rely on Feenstra (1994)'s method to estimate elasticities of substitution. Through a Monte Carlo experiment, simulated estimates suggest substantial biases due to weak instruments. However, the derivation of the elasticity of substitution drastically mitigates these biases.

Book Description
This paper builds a dynamic industry model with heterogeneous firms that explains why international trade induces reallocations of resources among firms in an industry. The paper shows how the exposure to trade will induce only the more productive firms to enter the export market (while some less productive firms continue to produce only for the domestic market) and will simultaneously force the least productive firms to exit. It then shows how further increases in the industry's exposure to trade lead to additional inter-firm reallocations towards more productive firms. These phenomena have been empirically documented but can not be explained by current general equilibrium trade models, because they rely on a representative firm framework. The paper also shows how the aggregate industry productivity growth generated by the reallocations contributes to a welfare gain, thus highlighting a benefit from trade that has not been examined theoretically before. The paper adapts Hopenhayn's (1992a) dynamic industry model to monopolistic competition in a general equilibrium setting. In so doing, the paper provides an extension of Krugman's (1980) trade model that incorporates firm level productivity differences. Firms with different productivity levels coexist in an industry because each firm faces initial uncertainty concerning its productivity before making an irreversible investment to enter the industry. Entry into the export market is also costly, but the firm's decision to export occurs after it gains knowledge of its productivity.

Book Description
The objective of this dissertation is to examine multi-product firms' productivity and export behavior. More specifically, this dissertation estimates productivity of firms that produce and sell multiple products, and the role of productivity in such firms' export behavior. In doing so, this dissertation develops a firm-level gravity approach to test whether multi-product firms self select to export or learn from exporting. In the first of part of this dissertation, I examine whether intra-firm resource reallocation of a multi-product firm affects its Total Factor Productivity (TFP). By extending earlier approaches, I estimate unbiased and consistent TFP of multi-product firms using a revenue-based production function. I find that TFP is more likely to be overestimated when multi-product firms' internalized demand linkage is not taken into account. I also find that multi-product firms' TFP decreases as it expands the number of products produced, but specialization of production does not play a role in TFP. In the second part, I present a theoretical framework to derive a firm-level gravity equation. By equating the total demand and total production of multi-product firms, I derive a firm-level gravity equation where export flows from firms to consumers is proportional to the product of economic size of firms, consuming power of a representative consumer, and trade resistance between origin and destination. Using the firm-level gravity equation, I test the hypothesis that high productivity firms self select to export and that the size of export flows is determined by productivity. I find that the economic size of exporting firms and the consuming power of a representative consumer have a positive and statistically significant effect on exports, while trade resistance such as tariff and distance have the opposite effect. I also find that the estimated coefficients of the firm-level gravity equation tend to be smaller than those of the traditional country-level gravity equation. In the final part of the dissertation, I test whether or not previous export experience improves the productivity of firms. Again, the estimable equation is derived from the equilibrium condition presented in the second part. My result confirms that previous export experience indeed improves productivity of exporting firms, but tariffs have the opposite effect. The results of this dissertation reveal the economic behavior of multi-product firms, which usually account for a large of economic activity and output in many countries. Understanding such firms' productivity and export behavior can offer strategies for economic growth and development. Empirical findings of this dissertation suggest policy options including lowering tariffs, and improving infrastructure that can lower transportation costs. Further examination of product range and specialization of production can offer strategies to source exports from small and midsize firms.

Book Description
A timely investigation of the potential economic effects, both realized and unrealized, of artificial intelligence within the United States healthcare system. In sweeping conversations about the impact of artificial intelligence on many sectors of the economy, healthcare has received relatively little attention. Yet it seems unlikely that an industry that represents nearly one-fifth of the economy could escape the efficiency and cost-driven disruptions of AI. The Economics of Artificial Intelligence: Health Care Challenges brings together contributions from health economists, physicians, philosophers, and scholars in law, public health, and machine learning to identify the primary barriers to entry of AI in the healthcare sector. Across original papers and in wide-ranging responses, the contributors analyze barriers of four types: incentives, management, data availability, and regulation. They also suggest that AI has the potential to improve outcomes and lower costs. Understanding both the benefits of and barriers to AI adoption is essential for designing policies that will affect the evolution of the healthcare system.

Book Description
Richard B. Freeman and James L. Medoff’s now classic 1984 book What Do Unions Do? stimulated an enormous theoretical and empirical literature on the economic impact of trade unions. Trade unions continue to be a significant feature of many labor markets, particularly in developing countries, and issues of labor market regulations and labor institutions remain critically important to researchers and policy makers. The relations between unions and management can range between cooperation and conflict; unions have powerful offsetting wage and non-wage effects that economists and other social scientists have long debated. Do the benefits of unionism exceed the costs to the economy and society writ large, or do the costs exceed the benefits? The Economics of Trade Unions offers the first comprehensive review, analysis and evaluation of the empirical literature on the microeconomic effects of trade unions using the tools of meta-regression analysis to identify and quantify the economic impact of trade unions, as well as to correct research design faults, the effects of selection bias and model misspecification. This volume makes use of a unique dataset of hundreds of empirical studies and their reported estimates of the microeconomic impact of trade unions. Written by three authors who have been at the forefront of this research field (including the co-author of the original volume, What Do Unions Do?), this book offers an overview of a subject that is of huge importance to scholars of labor economics, industrial and employee relations, and human resource management, as well as those with an interest in meta-analysis.
