This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of technological change in labor market polarization has been subject to recent critique. This paper finds that changes in production technology played an important role in wage and job polarization in the US. It also demonstrates that such technological change is consistentwith the timing of labor market polarization in the US, including the stagnation of the 50/10 wage percentile ratio and the slowdown of employment growth in high-wage jobs from the 2000s. The paper does so using a model with two key ingredients: 1) directed search and 2) two-sided multi-dimensional heterogeneity. Estimation results show that the complementarity between cognitive skill and task increased while that between manual skill and task did not. The full model can fullyaccount for the rise and fall of the 90/50 and 50/10 wage percentile ratios respectively. It also generates 72.6 percent of the rise in employment share of high-paying jobs relative to middling jobs and 69 percent of the fall in employment share of middling jobs relative to low-paying jobs. The paper suggests that the stagnation of the 50/10 wage ratio may be due to rank-switching between workers across the wage distribution from the 2000s, while the slowdown of employment growthin high-wage jobs may result from the trade-off between the returns to applying for high-wage jobs and the likelihood of being hired.

Book excerpt: In my thesis, I study the effects of agents' heterogeneity on labor market outcomes, with particular focus on sorting, performance, wages, and inequality. Chapter one studies multidimensional matching between workers and jobs. Workers differ in manual and cognitive skills and sort into jobs that demand different combinations of these two skills. To study this multidimensional sorting, I develop a theoretical framework that generalizes the unidimensional notion of assortative matching. I derive the equilibrium in closed form and use this explicit solution to study biased technological change. The key finding is that an increase in worker-job complementarities in cognitive relative to manual inputs leads to more pronounced sorting and wage inequality across cognitive relative to manual skills. This can trigger wage polarization and boost aggregate wage dispersion. I then estimate the model for the US during the 1990s. I identify a significant increase in complementarities of cognitive inputs and in cognitive skill-bias in production. Counterfactual exercises suggest that these technology shifts can account for observed changes in worker-job sorting, wage polarization and a significant part of the increase in US wage dispersion. Chapter two develops a theory that links differences in men's and women's social networks to disparities in their labor market performance. We are motivated by our empirical finding that men's and women's networks differ. Men have a higher degree (more network links) than women, but women have a higher clustering coefficient (a woman's friends are also friends among each other). In our model, a worker with a higher degree has better access to information. In turn, a worker with a higher clustering coefficient faces more peer pressure. Both peer pressure and access to information can attenuate a team moral hazard problem in the work place. But whether peer pressure or access to information is more important depends on the work environment. We find that, in environments where uncertainty is high, information is crucial and, therefore, men outperform women / in line with findings from sectors with high earnings' uncertainty like the financial or film industry.

Available in PDF, EPUB and Kindle. Book excerpt: This work quantifies the effects of discrepancies between local supply and demand for skills on wages, employment, and mobility rates of laid-off workers. I propose the concept of local skill remoteness to capture the degree of dissimilarity between the skill profiles of workers and jobs in a local labor market. I implement a measure of local skill remoteness at the occupation-city level, and find that higher skill remoteness at layoff is associated with lower re-employment rates and lower wages upon re-employment. Earnings differences between the top and bottom skill remoteness quartiles amount to a loss of 15% of the median worker's annual income and persist for at least two years. Skill-remote workers also have a higher probability of changing occupation, a lower probability of being re-employed at jobs with similar skill profiles, a higher propensity to migrate to another city and, conditional on migration, a higher likelihood of becoming less skill-remote. Motivated by this evidence, I develop a search-and-matching model with two-sided heterogeneity that provides a natural framework to interpret my skill remoteness measure. I use a calibrated version of the model to show that subsidies to on-the-job training lower the average skill remoteness of unemployed workers, thus the aggregate unemployment rate. The marginal benefit of such a policy is increasing in the level of unemployment.

Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the decline in labor market turnover over recent decades, in particular, the job finding and separation rates. I analyze the role of an increase in specialization of jobs in accounting for this decline, where specialization is defined as the impact of mismatch on match productivity. Combining individual level data from NLSY79 and NLSY97 with data on skills from ASVAB and O*NET, I empirically estimate job specialization and show that the specialization has increased over time. To quantify the impact of this increasing specialization on labor market turnover, I build an equilibrium search and matching model with two-sided ex-ante heterogeneity and endogenous separations. The calibrated model shows that higher job specialization leads to a decline in both job finding and separation rates. As specialization increases, firms and workers become more selective in forming matches. Thus, well-matched firms and workers choose to remain in their matches longer, while bad matches get destroyed faster. Since higher specialization leads to an increase in the proportion of good matches in the economy, it results in a decline in the labor market turnover.

Book excerpt: My dissertation focuses on the heterogeneity in labor markets. The first chapter proposes an explanation for the unemployment rate difference between skill groups. Low skill workers (workers without a four year college degree) have a higher unemployment rate. The reason for that " ... is mainly because they (low skill workers) are more likely to become unemployed, not because they remain unemployed longer, once unemployed" (Layard, Nickell, Jackman, 1991, p. 44). This chapter proposes an explanation for the difference in job separation probabilities between these skill groups: high skill workers have lower job separation probabilities as they are selected more effectively during the hiring process. I use a labor search model with match specific quality to quantify the explanatory power of this hypothesis on differences in job separation probabilities and unemployment rates across skill groups. The second chapter analyzes the effects of one channel of interaction (job competition) between skill groups on their labor market outcomes. Do skilled workers prefer unskilled jobs to being unemployed? If so, skilled workers compete with unskilled workers for those jobs. Job competition generates interaction between the labor market outcomes of these groups. I use a heterogeneous agents model with skilled and unskilled workers in which the only interaction across groups is the job competition. Direct effects of job competition are reducing skilled unemployment rate (since they have a bigger market) and increasing the unskilled unemployment rate (since they face greater competition). However number of vacancies respond to job competition in equilibrium. For instance, unskilled firms have incentives to open more vacancies since filling a vacancy is easier if there is job competition. Thus how unskilled unemployment and wages are affected by job competition depends on which effect dominates. The results for reasonable parameter values show that job competition does reduce the average unemployment rate. It reduces the skilled unemployment rate more, generating an increase in unemployment rate inequality. However, the employment rate at skilled jobs is unaffected. The third chapter focuses on skill biased technological change. Skill biased technological change is one of the explanations for the asymmetry between labor market outcomes of skill groups over the last few decades. However, during this time period there were also skill neutral shocks that could contribute to these outcomes. The third chapter analyzes the effects of skill biased and neutral shocks on overall labor market variables. I use a model in which skilled and unskilled outputs are intermediate goods, and final good sector receives all the shocks. A numerical exercise shows that both skilled and unskilled unemployment rates respond to shocks in the same direction. The response of unemployment rate to skill neutral shocks is bigger than the response to skill biased shocks for both skill groups. However, the unskilled unemployment changes more than the skilled unemployment rate as a response to skill neutral shocks. Thus, skill neutral shocks reduce the unemployment rate gap between skill groups.

Available in PDF, EPUB and Kindle. Book excerpt: This paper studies aggregate labor market dynamics when workers have heterogeneous skills for tasks which are subject to non-uniform labor demand shocks. When workers have different skills, movements in aggregate wages partly reflect a reallocation of different workers across tasks and into employment. This ensures that there nearly always exists some combination of task-specific demand shocks that induce aggregate employment and wages to negatively comove even in a frictionless economy. Furthermore, such reallocations would be interpreted either as a labor wedge or as a shift in an aggregate labor supply curve in representative agent economies. Developing a method to estimate the multidimensional skill distribution, I show that a frictionless model with realistic heterogeneity can replicate the mean wage increase and employment collapse of the Great Recession. Reduced-form composition-adjustment methods recover positive co-movements between employment and wages in recent periods suggesting an increasing role for composition effects through time, which the model rationalizes through changes in the skill distribution and composition of sectoral shocks.

This book was released on 2017-06-04 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skilled technical occupationsâ€"defined as occupations that require a high level of knowledge in a technical domain but do not require a bachelor's degree for entryâ€"are a key component of the U.S. economy. In response to globalization and advances in science and technology, American firms are demanding workers with greater proficiency in literacy and numeracy, as well as strong interpersonal, technical, and problem-solving skills. However, employer surveys and industry and government reports have raised concerns that the nation may not have an adequate supply of skilled technical workers to achieve its competitiveness and economic growth objectives. In response to the broader need for policy information and advice, Building America's Skilled Technical Workforce examines the coverage, effectiveness, flexibility, and coordination of the policies and various programs that prepare Americans for skilled technical jobs. This report provides action-oriented recommendations for improving the American system of technical education, training, and certification.

Book excerpt: We develop an equilibrium search-matching model with risk-neutral agents and two-sided ex-ante heterogeneity Unemployment insurance has the standard effect of reducing employment, but also helps workers to get a suitable job. The predictions of our simple model are consistent with the contrasting performance of the labor market in Europe and US in terms of unemployment, productivity growth and wage inequality. To show this, we construct two fictitious economies with calibrated parameters which only differ by the degree of unemployment insurance and assume that they are hit by a common technological shock which enhances the importance of mismatch. This shock reduces the proportion of jobs which workers regard as acceptable in the economy with unemployment insurance (Europe). As a result, unemployment doubles in this economy. In the laissez-faire economy (US), unemployment remains constant, but wage inequality increases more and productivity grows less due to larger mismatch. The model can be used to address a number of normative issues.

Book excerpt: We study variation in skill demands across firms and labor markets using job vacancy postings. We categorize a wide range of keywords found in job ads into ten general skills. We find a positive correlation between average wages and cognitive skill and social skill requirements that remains even after controlling for occupation, industry, and MSA fixed effects. We also find a positive correlation between these skill requirements and indicators of firm performance such as revenue per worker and whether the firm is publicly traded. These returns are concentrated among ads that specify both a cognitive and social skill requirement. Job skills have explanatory power for pay and firm performance, beyond what is available in widely-used labor market data.

Download or read book Studies of Labor Market Intermediation written by David H. Autor and published by University of Chicago Press. This book was released on 2009-12-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the traditional craft hiring hall to the Web site Monster.com, a multitude of institutions exist to facilitate the matching of workers with firms. The diversity of such Labor Market Intermediaries (LMIs) encompasses criminal records providers, public employment offices, labor unions, temporary help agencies, and centralized medical residency matches. Studies of Labor Market Intermediation analyzes how these third-party actors intercede where workers and firms meet, thereby aiding, impeding, and, in some cases, exploiting the matching process. By building a conceptual foundation for analyzing the roles that these understudied economic actors serve in the labor market, this volume develops both a qualitative and quantitative sense of their significance to market operation and worker welfare. Cross-national in scope, Studies of Labor Market Intermediation is distinctive in coalescing research on a set of market institutions that are typically treated as isolated entities, thus setting a research agenda for analyzing the changing shape of employment in an era of rapid globalization and technological change.

Available in PDF, EPUB and Kindle. Book excerpt: The introduction of a search and bargaining model to assess the welfare effects of minimum wage changes and to determine an “optimal” minimum wage. In The Minimum Wage and Labor Market Outcomes, Christopher Flinn argues that in assessing the effects of the minimum wage (in the United States and elsewhere), a behavioral framework is invaluable for guiding empirical work and the interpretation of results. Flinn develops a job search and wage bargaining model that is capable of generating labor market outcomes consistent with observed wage and unemployment duration distributions, and also can account for observed changes in employment rates and wages after a minimum wage change. Flinn uses previous studies from the minimum wage literature to demonstrate how his model can be used to rationalize and synthesize the diverse results found in widely varying institutional contexts. He also shows how observed wage distributions from before and after a minimum wage change can be used to determine if the change was welfare-improving. More ambitiously, and perhaps controversially, Flinn proposes the construction and formal estimation of the model using commonly available data; model estimates then enable the researcher to determine directly the welfare effects of observed minimum wage changes. This model can be used to conduct counterfactual policy experiments—even to determine “optimal” minimum wages under a variety of welfare metrics. The development of the model and the econometric theory underlying its estimation are carefully presented so as to enable readers unfamiliar with the econometrics of point process models and dynamic optimization in continuous time to follow the arguments. Although most of the book focuses on the case where only the unemployed search for jobs in a homogeneous labor market environment, later chapters introduce on-the-job search into the model, and explore its implications for minimum wage policy. The book also contains a chapter describing how individual heterogeneity can be introduced into the search, matching, and bargaining framework.

Available in PDF, EPUB and Kindle. Book excerpt: Temporary recruitment is a fast growing labor market with candidates, usually professionals, looking for contract positions in today’s fast evolving and dynamic economy. While two-sided matching algorithms have been applied to some labor markets during the past decades, they usually assume a static environment in which the strategic interactions between candidates and employers are designed without considering dynamic changes in market participants. In recent years, the advance of Internet and mobile technologies has enabled the implementation of large scale online labor markets which can capture the dynamics of the participants in a near real time manner. In this thesis, I study how to improve the effectiveness and the efficiency of recruitment processes in the context of temporary labor markets. The key challenge is how to design two-sided matching algorithms to accommodate dynamic changes in market participants. To have a better understanding of the challenge and possible solutions, I first analyzed the problem using the Environment-Based Design (EBD) methodology. The analyzing results show that two aspects need to by improved in the proposed two sided matching algorithm: the efficiency, which is the responsiveness of the algorithm, and the effectiveness, which is measured by the consistency of solutions generated by the algorithm when dynamics are introduced. Based on the results derived from EBD analysis, I designed two algorithms to improve the efficiency and the effectiveness. For the efficiency, I designed a request-accumulated deferred acceptance algorithm, which is a modification of the classical deferred acceptance algorithm. In addition, I designed a repair-based two-sided matching algorithm to improve solution consistency when changes are introduced to the market. The performance of the proposed algorithms are evaluated through a computational study. The results show that the efficiency and the effectiveness design requirements are satisfied.
