Book Description
This dissertation studies trade liberalization and labor market outcomes. The first two chapters examine the impact of China's trade liberalization on the adjustment of U.S. labor market for skilled and unskilled workers in a dynamic general equilibrium framework with firm heterogeneity and factor proportions. In the first chapter, I most specifically look into the effect of trade cost reduction on U.S. skill premium in an environment which I abstract from labor market friction. Featuring labor market search and matching frictions, the second chapter is part of a broader agenda on the labor market effect of China's trade liberalization and U.S. firms' offshoring decisions, with a greater focus on the dynamics of unemployment of skilled and unskilled workers. The third chapter investigates the impact of the China's increased trade openness on its local labor market. It examines the effects of China's domestic migration policy change and trade liberalization on wage inequality in China using a dynamic general equilibrium model of international trade and internal migration across regions. This dissertation showcases some of the ways trade policy can interact with firms' endogenous offshoring and entry decisions, workers' mobility choices, and labor markets frictions in a dynamic fashion. More specifically, the first chapter studies how wage inequality between skilled and unskilled workers interact with multinational firms' decisions and countries' different factor endowments using a two-country dynamic stochastic model featuring task-offshoring, heterogeneous firms and factor proportions. It shows that besides the traditional Stolper-Samuelson mechanism that shifts factors of production towards a country's comparative advantage sectors, there also exist other firm-level adjustment mechanisms that widen the wage gap after trade liberalization. It finds that in the short run, offshoring widens wage inequality between skilled and unskilled workers through increasing high-skilled wage and lowering low-skilled wage. Such effect is more announced in the beginning phase of the adjustment, and slows down over time as low-skilled wage rises faster than the cool-down of high-skilled wage increase. The intensive margin and the extensive margin are both active in shaping rising wage gap in the home country, with the latter playing a more important role in the short to medium run compared to the beginning stage following the shock. The second chapter studies the dynamic effects of offshoring on the unemployment rates and wage inequality across the high-skilled and low-skilled workers through the dynamics of firms' production location and entry decisions in general equilibrium. First, I examine the dynamic effects of offshoring cost reduction due to China's trade liberalization. Estimates from vector autoregressions (VARs) show that a decrease in offshoring costs is associated with a short-lived increase in low-skilled unemployment, but a persistent decline in high-skilled unemployment and a less persistent expansion of wage gap in the source country. Second, I build a two-country trade-in-task model with firm heterogeneity, endogenous selection into entry and offshoring as well as search and matching frictions to study the channels through which offshoring cost reductions affect the labor market outcomes for different skill groups over time. The model successfully reproduces the VAR evidence and highlights the importance of endogenous firm entry and labor market frictions in generating the empirical dynamic responses of wage and unemployment across different skill groups. The third chapter investigates China's labor market's responses to its own trade liberalization, which is a relatively less explored topic compared to the relationship between the China shock and labor market changes in other countries. Using data from CHIP (Chinese Household Income Project), this chapter aims to fill this gap by estimating the effects of trade liberalization on Chinese local labor markets. In addition, it investigates changes in urban to rural wage inequality and skill premium in urban and rural areas separately with the availability of surveys conducted in urban and rural households. In the model, a dynamic general equilibrium framework with heterogeneous firms, heterogeneous workers and internal migration is employed to study the impact of policy-generated trade cost reduction and easing of migration restrictions on Chinese wage inequality. I focus on the role of labor mobility that characterizes the large rural-to-urban migration in the midst of trade liberalization in shaping skill premium and urban to rural wage inequality. Calibrating the changes in policy-generated migration cost reduction and trade cost decline, as well as productivity increase in the tradable sector, this paper analyzes the responses of different measures of wage inequality and other macroeconomics variables following these shocks. This dissertation highlights the role of interaction of firm dynamics, factor endowments and labor market frictions in shaping the labor market adjustments. The positive effects of offshoring on the labor market for workers regardless of skill levels suggest that more trade frictions designed to restrict offshoring is likely to hinder firm entry, which is a key driver that contributes to higher wages and lower unemployment rates of both skilled and unskilled workers over time. It also points to the importance of labor market reforms by showing that easing of migration restriction and search and matching frictions are both beneficial to exports and wages of all workers, with consequences of rising wage inequality though.

Book Description
Labor Markets and Business Cycles integrates search and matching theory with the neoclassical growth model to better understand labor market outcomes. Robert Shimer shows analytically and quantitatively that rigid wages are important for explaining the volatile behavior of the unemployment rate in business cycles. The book focuses on the labor wedge that arises when the marginal rate of substitution between consumption and leisure does not equal the marginal product of labor. According to competitive models of the labor market, the labor wedge should be constant and equal to the labor income tax rate. But in U.S. data, the wedge is strongly countercyclical, making it seem as if recessions are periods when workers are dissuaded from working and firms are dissuaded from hiring because of an increase in the labor income tax rate. When job searches are time consuming and wages are flexible, search frictions--the cost of a job search--act like labor adjustment costs, further exacerbating inconsistencies between the competitive model and data. The book shows that wage rigidities can reconcile the search model with the data, providing a quantitatively more accurate depiction of labor markets, consumption, and investment dynamics. Developing detailed search and matching models, Labor Markets and Business Cycles will be the main reference for those interested in the intersection of labor market dynamics and business cycle research.

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
Globalization and unemployment are two phenomena which are amongst the most widely discussed subjects in the economic debate today. Often, globalization is regarded as being responsible for the increase in unemployment, particularly in unskilled labor. This book deals with the correlation between globalization and unemployment under various aspects: historical aspects of globalization, empirical trends and theoretical explanations of unemployment, effects of globalization in general and of European Monetary Union in particular on umemployment, labor market policy in a global economy, the impact of fiscal policy on unemployment in a global economy, as well as the effects of globalization on inflation and national stabilization policy.

Book Description
Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.

Book Description
This paper highlights how changes in the composition of demand affect income dispersion in the short run. We first document how the share of aggregate spending dedicated to labour-intensive goods and services shrinks (expands) during downturns (booms), and argue that this contributes to the observed pro-cyclicality of employment and output in labour-intensive industries. Using a two-sector general equilibrium model, we then assess how this demand composition channel influences the cyclical properties of the income distribution. Consistent with empirical evidence, we find income inequality to be countercyclical due to changes in the level of employment and (to a lesser extent) relative factor prices. The model also shows that wealth redistribution policies can potentially involve a trade-off between equality and output, depending on how they affect the composition of aggregate demand.

Book Description
What happens if an employer cuts wages by one cent? Much of labor economics is built on the assumption that all the workers will quit immediately. Here, Alan Manning mounts a systematic challenge to the standard model of perfect competition. Monopsony in Motion stands apart by analyzing labor markets from the real-world perspective that employers have significant market (or monopsony) power over their workers. Arguing that this power derives from frictions in the labor market that make it time-consuming and costly for workers to change jobs, Manning re-examines much of labor economics based on this alternative and equally plausible assumption. The book addresses the theoretical implications of monopsony and presents a wealth of empirical evidence. Our understanding of the distribution of wages, unemployment, and human capital can all be improved by recognizing that employers have some monopsony power over their workers. Also considered are policy issues including the minimum wage, equal pay legislation, and caps on working hours. In a monopsonistic labor market, concludes Manning, the "free" market can no longer be sustained as an ideal and labor economists need to be more open-minded in their evaluation of labor market policies. Monopsony in Motion will represent for some a new fundamental text in the advanced study of labor economics, and for others, an invaluable alternative perspective that henceforth must be taken into account in any serious consideration of the subject.
