Book excerpt: Sectoral shifts of labor demand can have signiƠ̐1cant eƠ̐0ects on aggregate rate and duration of unemployment, and this is known as sectoral shifts hypothesis. To mea℗Ơsure the sectoral shifts, past studies use David M. Lilien0́9s dispersion measure which represents the eƠ̐0ect of the changes in the distribution of sectoral shocks on aggregate rates of layoƠ̐0s. This dissertation proposes an improved measure of sectoral shifts and tests the sectoral shifts hypothesis. It shows that, when the distribution of sectoral shocks is asymmetric, dispersion alone is not suƠ̐3cient to capture the eƠ̐0ect of the changes in distribution and, the skewness of the distribution can have a signiƠ̐1cant role in the approximation of aggregate rates of layoƠ̐0s. Empirical results show a sig℗ƠniƠ̐1cant eƠ̐0ect of the skewness measure on the aggregate rate of unemployment. The results also lend a strong support for the sectoral shifts hypothesis in Lilien type and Abraham-Katz type models, which contrasts with the rejection of the hypothesis in previous studies of the Abraham-Katz type models. One concern about these empirical results is that the classical measures of disper℗Ơsion and skewness are very sensitive to the presence of outliers and consequently the test of the hypothesis can be distorted by this presence. Strong evidence exists for the presence of outliers in the distribution of estimated sectoral shocks. Various robust measures of dispersion and skewness are computed. The sectoral shifts hypothesis is still strongly supported when the robust measures are used. This reinforces the empirical Ơ̐1ndings under the classical measures. When the mobility of workers across sectors is limited because of frictions in the labor market, workers who become unemployed due to sectoral shifts of labor demand will experience a longer duration of unemployment because of the time associated with switching sectors. Therefore, for a given rate of unemployment, a higher proportion of these workers will increase the average duration of unemployment. Empirical results show that sectoral shifts have a statistically greater eƠ̐0ect on the average duration of unemployment than cyclical Ơ̐2uctuations. Sectoral shifts help explain unusual upward trends in the duration of unemployment in the 1990s.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis comprises three chapters that delve into various labor market dynamics and the policy implications in the context of the COVID-19 pandemic and its aftermath. In the first chapter (joint with Andre Kurmann and Etienne Lale), we investigate the dynamics of small businesses and employment using real-time data from the private sector throughout the COVID-19 crisis. The pandemic has led to an explosion of research using private-sector data to measure small business activity. Yet important questions remain about sample representativeness and how to identify business openings and closings. We propose new methods to address these issues by exploiting information on business activity from Google, Facebook, and Safegraph. We apply our methods to Homebase data and show that the resulting estimates closely fit official statistics. We then use the data to study whether small businesses have been hit harder by the pandemic and the extent to which the Paycheck Protection Program helped mitigate these effects. The second chapter (joint with Andreas Hornstein, Marios Karabarbounis, Andre Kurmann, Etienne Lale) focus on the effects of pandemic unemployment insurance (UI) benefits. UI acts as both a disincentive for labor supply and as a stimulus for labor demand. In equilibrium, the two effects combine, which may explain why several studies have found only small negative effects of the generous UI expansions during the pandemic on job finding rates and employment. In this paper we propose a new research design to estimate independently the disincentive effects of pandemic unemployment benefits. Using high-frequency worker-firm matched data from Homebase, we document that employment of low-wage businesses recovered more slowly from the initial pandemic shock than neighboring high-wage businesses, and that this recovery gap is significantly related to the relative generosity of UI benefits. By comparing neighboring businesses that are largely sharing the benefits of the local UI stimulus, our research design identifies more closely the disincentive effects of pandemic UI benefits. We use an equilibrium model of labor search with heterogeneity in firms and workers to translate the reduced-form estimate of the recovery gap into an unemployment duration elasticity and an aggregate employment loss. Our model, which captures well the recovery gap between low- and high-wage businesses, implies relatively low duration elasticities. Yet, the sheer size and multitude of the pandemic programs implies that the disincentive effects arising from the pandemic UI benefits are substantial and amount to 5 percent of normal employment. The third chapter studies work-from-home (WFH) work mode's implications on labor market. The COVID-19 pandemic has triggered a widespread adoption of WFH practices and accelerated the advancement of remote work technologies. Surprisingly, even after the pandemic has subsided, a substantial shift towards WFH remains evident among workers. However, the accessibility to WFH is not uniform across all types of workers. Notably, high-tech industries, characterized by a predominantly high-skilled workforce, exhibit a higher prevalence of WFH. This raises concerns about the effects of WFH on workers employed in industries where remote work is unfeasible. In this paper, I develop a spatial equilibrium model that incorporates WFH to examine the implications on workers' mobility, local market outcomes, and overall welfare. I find 3 key insights: (1) there is a productivity threshold for WFH adoption, (2) there is a one-way dependence of low-skilled workers on high-skilled workers' mobility, and (3) if workers are fully mobile, both types of workers benefit from the introduction of WFH.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis develops empirical methodologies to investigate the effect of globalization on welfare and inequality both between- and within-countries. The first essay proposes a Roy-like model where workers are heterogeneous ill terms of their comparative and absolute advantage. We show that the schedules of comparative and absolute advantage (i) determine changes in the average and the variance of the log-wage distribution, and (ii) are nonparamnetrically identified from the cross-regional variation in the sectoral responses of employment and wages to observable sector-level demand shifters. Applying these results, we find that the rise in world commodity prices accounts for 5-10% of the fall in Brazilian wage inequality between 1991 and 2010. The second essay develops a methodology to construct nonparametric counterfactual predictions, free of functional-form restrictions on preferences and technology, in neoclassical models of international trade. First, we establish the equivalence between such models and reduced exchange models in which countries directly exchange factor services. This equivalence implies that, for an arbitrary change in trade costs, counterfactual changes in factor prices, and welfare only depend on the shape of a reduced factor demand system. Second, we provide sufficient conditions for the nionparainetric identification of this system. Together, these results offer a strict generalization of the parametric approach used in so-called gravity models. Finally, we use China's recent integration into the world economy to illustrate tile feasibility of our approach. The third essay investigates the connection between the recent rise in services trade and changes in labor market outcomes in different countries. We develop a theoretical framework where trade in services arises from the spatial unbundling of workers' task output. Transmission costs endogenously determine the magnitude of between-sector task trade both within a country ("outsourcing") and between countries ("offshoring"). We show that, while differentials in sectoral task prices decrease in response to outsourcing, they increase in response to offshoring. The heterogeneity in the composition of workers' task endowments controls responses in between- and within-sector wage inequality across countries.

Available in PDF, EPUB and Kindle. Book excerpt: The behaviour of US productivity since this book was originally publishedin 1994, has added new relevance to the relationship between profits and productivity. In the long run, productivity growth determines the economic standard of living. This book is divided into three parts: the basis of the first is the empirical finding that, controlling for normal business cycle effects, productivity grows faster when profits have been low than otherwise. The second part discusses how to measure marginal cost using time series data and the third tests a basic assumption that productivity growth is exogenous to labour and capital.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation I explore the relationship between structural change and globalization. In particular, I focus on the impact of international trade on sectoral labor markets. In Chapter 1, by using a growth accounting framework I provide quantitative estimates of the impact of international trade on sectoral employment shares, in the presence of structural change. I find that in the USA between 1995 and 2014, international trade accounts for 16 percent of the decline in the goods sector employment share. Across countries, the impact of trade on the goods sector employment share is heterogeneous in sign and magnitudes, and is correlated with comparative advantage in the goods sector. I then introduce a Ricardian model of trade with structural change, to shed light on the comparative advantage mechanism. In the data and in the model, international trade mitigates structural change forces in countries with a comparative advantage in the goods sector, while it magnifies structural change forces in countries with a comparative advantage in the service sector. The framework and results I present suggest that trade policy has a limited role in "bringing the manufacturing jobs back". In Chapter 2 I first document that changes in sectoral relative wages have been heterogeneous across countries and then show that these changes in sectoral relative wages matter for understanding employment reallocation. I then ask: why do sectoral relative wages evolve over time? I argue that a likely explanation is the existence of idiosyncratic sectoral labor demand shocks in the context of employment reallocation frictions. I argue that aggregate trade integration con generate such shifts. The intuition is simple: trade liberalization tends to increase labor demand in sectors in which the country has a comparative advantage, and to decrease labor demand in sectors in the rest of sectors. If labor cannot fully reallocate after such shocks, wages tend to adjust: relative wages tend to increase in sectors in which the country has a comparative advantage and tend to shrink in the rest of the economy. Trade integration thus impacts sectoral relative wages and that this impact varies across countries. I introduce a model of international trade with labor market frictions and show that countries with a comparative advantage in the goods (service) sectors tend to experience increasing relative wages in the goods (service) sector. Using the Revealed Comparative Advantage Index, I confirm this relationship in the data. Employment reallocation frictions thus shed light on the empirical relevance of the Ricardian model of international trade.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation employs tools from Labor Economics and International Trade to study how workers and labor markets adjust to economic shocks arising from trade liberalization and technological change. It contributes to the existing literature by studying several economic mechanisms that determine the magnitudes of these adjustments. The first chapter of this dissertation analyzes the roles that skill transferability and the local industry mix have on the adjustment costs of workers affected by negative trade shocks. Using rich administrative data from Germany, we construct novel measures of economic distance between sectors based on the notion of skill transferability. We combine these distance measures with sectoral employment shares in German regions to construct an index of labor market flexibility. This index captures the degree to which workers from a particular industry will be able to reallocate into other jobs. We then study the role of labor market flexibility on the effect of import shocks on the earnings and the employment outcomes of German manufacturing workers. Among workers living in inflexible labor markets, the difference between a worker at the 75th percentile of industry import exposure and one at the 25th percentile of exposure amounts to an earnings loss of roughly 11% of initial annual income (over a 10 year period). The earning losses of workers living in flexible regions are negligible. These findings are robust to controlling for a wide array of region level characteristics, including region size and overall employment growth. Our findings indicate that the industry composition of local labor markets plays an important role on the adjustment processes of workers. In the second chapter, we develop and apply a framework to quantify the effect of trade on aggregate welfare as well as the distribution of this aggregate effect across different groups of workers. The framework combines a multi-sector gravity model of trade with a Roy-type model of the allocation of workers across sectors. By opening to trade, a country gains in the aggregate by specializing according to its comparative advantage, but the distribution of these gains is unequal as labor demand increases (decreases) for groups of workers specialized in export-oriented (import-oriented) sectors. The model generalizes the specific-factors intuition to a setting with labor reallocation, while maintaining analytical tractability for any number of groups and countries. Our new notion of "inequality-adjusted" welfare effect of trade captures the full cross-group distribution of welfare changes in one measure, as the counterfactual scenario is evaluated by a risk-averse agent behind the veil of ignorance regarding the group to which she belongs. The quantitative application uses trade and labor allocation data across regions in Germany to compute the aggregate and distributional effects of a shock to trade costs or foreign technology levels. For the extreme case in which the country moves back to autarky we find that inequality-adjusted gains from trade are larger than the aggregate gains for both countries, as between-group inequality falls with trade relative to autarky, but the opposite happens for the shock in which China expands in the world economy. In the third chapter, we use detailed production data from a large Latin American garment manufacturer to study the process of technology adoption and resulting productivity changes within a firm. We find that the adoption of modern manufacturing techniques increases productivity through two channels, a direct effect and a spillover effect across adjacent production units. By exploiting the gradual introduction of new manufacturing techniques across independent production units, we estimate a direct effect on productivity of roughly 30%. We also estimate large spillovers to neighboring untreated units which amount to a 25% increase in productivity. Both of these effects accumulate slowly over time. The timing and the magnitudes of the estimated spillover effects corroborate qualitative evidence consistent with knowledge diffusion, learning and imitation.

Available in PDF, EPUB and Kindle. Book excerpt: From workers' wages to presidential elections, labor unions once exerted tremendous clout in American life. In the immediate post-World War II era, one in three workers belonged to a union. The fraction now is close to one in five, and just one in ten in the private sector. The only thing big about Big Labor today is the scope of its problems. While many studies have explained the causes of this decline, What Unions No Longer Do shows the broad repercussions of labor's collapse for the American economy and polity. Organized labor was not just a minor player during the middle decades of the twentieth century, Jake Rosenfeld asserts. For generations it was the core institution fighting for economic and political equality in the United States. Unions leveraged their bargaining power to deliver benefits to workers while shaping cultural understandings of fairness in the workplace. What Unions No Longer Do details the consequences of labor's decline, including poorer working conditions, less economic assimilation for immigrants, and wage stagnation among African-Americans. In short, unions are no longer instrumental in combating inequality in our economy and our politics, resulting in a sharp decline in the prospects of American workers and their families.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three chapters. The first chapter concerns the secular changes in the U.S. firm size distribution and firm dynamics. This chapter sets up a quantitative model of firm dynamics with debt heterogeneity to study the implications of changes in real interest rates for the firm size distribution and firm dynamics. It shows that the decline in long-term real interest rates since the early 1980s can account for a significant fraction of the shift in employment shares to large firms as well as the decline in firms per capita and firm entry rates experienced in the U.S. over the same period. In the model, firms endogenously choose financial intermediaries issuing debt with either earnings-based (EBC) or asset-based (ABC) borrowing constraints. The two types of constraints arise naturally from the imperfect enforceability of debt contracts and are in line with recent empirical findings. A decline in real interest rates benefits firms with EBC more because they are not constrained by their assets and can expand more due to increased earnings. Since firms with higher earnings optimally choose earnings-based lending, the decline in real interest rates shifts employment shares to larger firms. Moreover, the growth of large firms crowds out smaller firms and firm entry through general equilibrium effects. The paper tests the mechanism in cross-country data from the OECD and finds a stronger association between the decline in real interest rates and changes in firm dynamics, especially in countries with deeper credit markets. In the second chapter, I study the effects of government regulations on firm dynamism. The impact of government regulations on the economy is a central topic in policy debates. However, due to the endogeneity of regulations and challenges in measuring them, these debates remain contentious. This paper establishes the causal effects of government regulations on firm dynamism by employing a novel shift-share (Bartik) instrument in conjunction with the RegData dataset, which quantifies regulations based on the text of federal regulatory documents. The primary assumption for identification is that, for each sector, the exposure to regulations from different government agencies at the beginning of the period is exogenous to any confounding factors. The findings reveal that government regulatory restrictions significantly increase firm exit rates and discourage the formation of establishments, while having no substantial impact on firm entry. Furthermore, these restrictions contribute to reduced job creation, elevated job destruction, and diminished overall employment. These effects are consistently observed across various age groups. The results lend support to the idea that government regulations can raise production costs for firms and/or enhance the monopolistic power of certain companies. Both mechanisms can diminish the profits of affected firms, leading to increased firm exit rates and reduced labor demand. Additionally, the findings refute the interpretation of regulations as solely serving as entry barriers. The final chapter of the dissertation investigates the labor market outcomes for involuntary part-time workers and their subsequent effects on welfare levels. Through an analysis of survey data, I demonstrate that involuntary part-time workers exhibit reservation wages comparable to those of unemployed workers. This similarity largely stems from parallel wage offers and offer arrival rates. Contrary to previous research, this finding indicates that involuntary part-time workers experience welfare levels akin to unemployed workers. One possible explanation for this discrepancy lies in the methodology of prior studies. Conclusions drawn from earlier research, which primarily focused on the faster transition of involuntary part-time workers into full-time positions compared to other workers, may be flawed. This is because these workers also tend to revert to their previous job types at a faster rate. To further explore the implications of these discoveries, I employ a quantitative search model. The calibrated model supports the assertion that involuntary part-time workers experience welfare levels similar to those of unemployed workers. Furthermore, the model suggests that neither extending unemployment insurance to part-time workers nor enhancing the likelihood that unemployed workers transition to part-time positions would effectively increase the prevalence of full-time employment

Book excerpt: This dissertation consists of three empirical papers exploring policy-relevant questions in Public Finance and Labor Economics. In particular, it inquires into social insurance programs, the purpose of which is to protect individuals against adverse events. More generous benefits, however, often lead to unintended behavioral responses even as they provide greater protection. This dissertation focuses on identifying and quantifying the distortionary effects of social insurance, providing an input to optimal design. The first chapter investigates the effect of Social Security dependent benefit provisions on the labor force participation of married women aged 25-54. Many provisions of the Social Security program may distort an individual's work incentive. In particular, the availability of dependent benefits may reduce the net return to work since secondary earners, who are likely to claim benefits based on their spouses' earnings records, pay the full payroll tax without receiving marginal benefits for additional earnings. I rely on differences in Social Security coverage among husbands by state and sector to identify the impact on the labor supply of their wives. The results show that married women tend to reduce their labor supply when dependent benefits are available, suggesting that changes in the Social Security system that strengthen the relationship between earnings and benefits would have a positive effect on the labor supply of married women. The second chapter analyzes how Social Security dependent benefit provisions affect women's divorce behavior. Under the current Social Security system, a divorced woman is eligible to receive dependent benefits based on her ex-spouse's earnings record if her marriage lasted at least 10 years and she remains unmarried after divorce. Using data from the Panel Study of Income Dynamics, I estimate a discrete time duration model of the probability of divorce. The results suggest that married women are likely to delay divorce to preserve the option of receiving dependent benefits if their marriages are near 10 years duration. This effect is stronger for women whose earnings are much lower than their husbands' or whose predicted remarriage probabilities are low, so are those most likely to value the option. The final chapter examines the effect of extended parental coverage on young adults' labor market choices. Young adults aged 19-29 are significantly less likely to have health insurance since most family insurance policies cut off dependents when they turn 19 or finish college. In recent years, several states have expanded eligibility to allow young adults as old as 30 to remain covered under their parents' employer-provided health insurance. For those who qualify for these benefits, the expansion of parental coverage partially reduces the value of being employed by a firm that provides health insurance since adult children can now get health insurance through another channel. We employ quasi-experimental variation in the timing and generosity of states' eligibility rules to identify the effect of the policy change on young adults' labor market choices. Our results suggest that the expansion of parental coverage increases the group coverage rate and reduces labor supply among young adults, particularly in full-time employment.

Available in PDF, EPUB and Kindle. Book excerpt: In the twentieth century, large companies employing many workers formed the bedrock of the U.S. economy. Today, on the list of big business's priorities, sustaining the employer-worker relationship ranks far below building a devoted customer base and delivering value to investors. As David Weil's groundbreaking analysis shows, large corporations have shed their role as direct employers of the people responsible for their products, in favor of outsourcing work to small companies that compete fiercely with one another. The result has been declining wages, eroding benefits, inadequate health and safety protections, and ever-widening income inequality. From the perspectives of CEOs and investors, fissuring--splitting off functions that were once managed internally--has been phenomenally successful. Despite giving up direct control to subcontractors and franchises, these large companies have figured out how to maintain the quality of brand-name products and services, without the cost of maintaining an expensive workforce. But from the perspective of workers, this strategy has meant stagnation in wages and benefits and a lower standard of living. Weil proposes ways to modernize regulatory policies so that employers can meet their obligations to workers while allowing companies to keep the beneficial aspects of this business strategy.

Available in PDF, EPUB and Kindle. Book excerpt: A Brookings Institution Press and American Assembly publication Slow job growth, declining home values, a diminishing tax base, and concentrated poverty are but a few of the growing obstacles for well-established but struggling cities. Challenged by decades of globalization, technological change, and dramatic demographic shifts away from the urban core, these former industrial powerhouses, particularly in the Northeast and Midwest, have been eclipsed by burgeoning American cities with a viable niche in the new economy. In Retooling for Growth, experts present new frameworks, cutting-edge analysis, and innovative policy solutions for the nation's government, business, civic, and community leaders to sculpt a sustainable and supportable economy for older industrial areas. The unique focus on rehabilitating weak market cities outlines ideas for reshaping the role of public agencies, the workforce, business organizations, and technology. Implementation of these measures addresses challenges such as fostering entrepreneurship, reducing poverty and inequality, and maintaining and augmenting the number of skilled professionals who reside and work in a community, among others. This collection of essays offers practical, achievable strategies for revitalizing industrial areas and building upon the potential of existing but overlooked resources of economic, physical, and cultural significance. In this important volume, leading authorities provide a thought-provoking analysis of healthy economic development practices for both public and private sectors.

Available in PDF, EPUB and Kindle. Book excerpt: Migration presents a stark policy dilemma. Research repeatedly confirms that migrants, their families back home, and the countries that welcome them experience large economic and social gains. Easing immigration restrictions is one of the most effective tools for ending poverty and sharing prosperity across the globe. Yet, we see widespread opposition in destination countries, where migrants are depicted as the primary cause of many of their economic problems, from high unemployment to declining social services. Moving for Prosperity: Global Migration and Labor Markets addresses this dilemma. In addition to providing comprehensive data and empirical analysis of migration patterns and their impact, the report argues for a series of policies that work with, rather than against, labor market forces. Policy makers should aim to ease short-run dislocations and adjustment costs so that the substantial long-term benefits are shared more evenly. Only then can we avoid draconian migration restrictions that will hurt everybody. Moving for Prosperity aims to inform and stimulate policy debate, facilitate further research, and identify prominent knowledge gaps. It demonstrates why existing income gaps, demographic differences, and rapidly declining transportation costs mean that global mobility will continue to be a key feature of our lives for generations to come. Its audience includes anyone interested in one of the most controversial policy debates of our time.
