Credit market constraints and labor market decisions

In this paper, we examine whether imperfections in credit markets spill over to other markets, particularly the labor market. We take the case of Italy, a country that experienced changes in the mortgage market brought about by the 1992 European unification and other institutional shifts. These events make Italy a good laboratory to study the effects of financial markets on the labor market. Using household data from the Bank of Italy between 1989 and 1993, we estimate the relationship between female participation and mortgage use. We find a significant impact of mortgages on women's participation in the labor market.     

Endogenous labor force participation and firing costs

I construct a matching model to explain the labor market transition between employment, unemployment and nonparticipation, and evaluate the quantitative effects of firing costs. The model has several features that are distinguished from previous studies: endogenous labor force participation, different job-search decisions and imperfect insurance markets. I find that the model is able to account for the U.S. labor market, especially the gross labor-force transition rates. I also find that firing costs as a type of firing tax have a negative effect on the layoff rate, the job-finding probability and the participation rate. In particular, the effect of a decrease in the job-finding probability is greater than the effect of a decrease in the layoff rate, and this results in an increase in the unemployment-to-population ratio. Finally, firing costs make individuals' job tenures longer and skew the asset distribution to the right.     

Social networks and labor market transitions

We study the influence of social networks on labor market transitions. We develop the first model where social ties and job status coevolve through time. Our key assumption is that the probability of formation of a new tie is greater between two employed individuals than between an employed and an unemployed individual. We show that this assumption generally generates negative duration dependence of exit rates from unemployment. Our model has a number of novel testable implications. For instance, we show that a higher connectivity among unemployed individuals reduces duration dependence and that exit rates depend positively on the duration of the last job held by the unemployed worker.     

Costly external finance and labor market dynamics

We study the role of agency frictions and costly external finance in cyclical labor market dynamics, with a focus on how credit-market frictions may amplify aggregate TFP shocks. The main result is that aggregate TFP shocks lead to large fluctuations of labor market quantities if the model is calibrated to the empirically observed countercyclicality of the finance premium. A financial accelerator mechanism thus amplifies labor market fluctuations by rendering rigidity in real wage dynamics. In contrast, if the finance premium is procyclical, which the model can be parameterized to accommodate, amplification is absent, and labor-market fluctuations display the Shimer (2005) puzzle.     

The national internal labor market encounters the local labor market: Effects on employee retention

Formal salary systems are commonplace among medium to large-sized firms and within the United States government. However, there is little evidence regarding the costs, if any, of such systems. This study analyzes the effects on retention within the United States Air Force from an inflexible wage system failing to adequately compensate personnel for local compensating wage differentials. Using location-specific Air Force personnel records, I compare the differences between military and civilian wages, by occupation, across locations to determine if local labor markets play a significant role in the stay or leave decisions for personnel. Results show that rigid wage constraints do in fact impose costs on the firm through increased turnover in locations that fail to adequately adjust wages for the cost of living and amenities.     

Informal adult care and caregivers' employment in Europe

I discuss instrumental variable estimates of the effect of providing unpaid adult care on the caregivers' probability of being employed, using eight waves of the European Community Household Panel. I focus on men aged 40–64 and women aged 40–59 from thirteen Member States, aggregated in two groups of Northern-Central and Southern countries. Previous papers with European data found that IV estimates are more negative than estimates assuming exogeneity of caregiving. I show that this difference is not robust once account is taken of time-invariant unobserved heterogeneity. Indeed, instruments turn out not to be needed, and the estimated effect is negative, but small in both groups of countries.     

Structural estimation of stock market participation costs

This paper develops and estimates a dynamic model of stock market participation, where consumers' decisions regarding stock market participation are influenced by participation costs. The practical significance of the participation costs is considered as being a channel through which financial education programs can affect consumers' investment decisions. Using household data from the Panel Study of Income Dynamics, I estimate the magnitude of the participation cost, allowing for individual heterogeneity in it. The results show the average stock market participation cost is about 4–6% of labor income; however, it varies substantially over consumers' life. The model successfully predicts the level of the observed participation rate and the increasing pattern of stock market participation over the consumers' life cycle.     

Instability in the labor market for researchers

R&D is both an activity which involves team effort, and with many of the features of a zero-sum game. This paper shows that these characteristics make the labor market for researchers unstable in the sense that firms have incentives to continuously change the composition of their research teams. Related results concerning the core of several cooperative games in characteristic form are also proved.     

Women of color in the labor market

While the labor force participation rates of women have increased, and women work in a wider range of occupations than they did two decades ago, there remain gaps between the status of women and men, as well as between white women and women of color. Additionally, as the female labor force becomes more diverse, there are also differences among women of color in labor force participation, unemployment, and occupational status. Based on projections regarding the future structure of the labor force, it is likely that even as the status of some women of color improves, many will remain stuck in low-wage service and clerical jobs.     

Structural change accounting with labor market distortions

This paper quantifies the relative importance of sectoral productivity and labor market distortions for structural change in the U.S., India, Mexico and Brazil between 1960 and 2005. I use census data to compute human capital by sector and infer labor market distortions as sectoral gaps in wage per unit of human capital. I incorporate these distortions into a model of structural change, and calibrate the model to reproduce the time paths of sectoral shares of labor and value added for each country. Counterfactuals reveal that (1) TFP growth in agriculture drives most of the decline in its share of labor; (2) the role of labor market distortions is limited.     

The early inception of labor market gender differences

This paper analyzes gender differences in jobs while in school using school-class-based samples, a setting in which education differences, “glass ceilings”, and career interruptions due to parenthood are irrelevant. I find that in this early stage of life boys already earn substantially more than girls. The earnings gap cannot be explained by differences in participation rates and hours of work, nor by gender wage gaps within job types. It is entirely due to the fact that girls work more in job types with relatively low wages, in particular babysitting. During the period considered, 1984–2001, the gender patterns of jobs while in school largely remained unchanged.     

The effectiveness of European active labor market programs

Active Labor Market Programs are widely used in European countries, but despite many econometric evaluation studies analyzing particular programs no conclusive cross-country evidence exists regarding “what program works for what target group under what (economic and institutional) circumstances?”. This paper aims at answering this question using a meta-analysis based on a data set that comprises 137 program evaluations from 19 countries. The empirical results of the meta-analysis are surprisingly clear-cut: Rather than contextual factors such as labor market institutions or the business cycle, it is almost exclusively the program type that seems to matter for program effectiveness. While direct employment programs in the public sector frequently appear detrimental, wage subsidies and “Services and Sanctions” can be effective in increasing participants' employment probability. Training programs – the most commonly used type of active policy – show modestly positive effects.     

Subsidizing low-skilled jobs in a dual labor market

We introduce a matching model that allows for classical and frictional unemployment. The labor market is dual featuring low-skilled and high-skilled workers and simple and complex jobs. Simple jobs pay a minimum wage, while wages in the complex jobs are determined by Nash bargaining. Opportunities for low-skilled workers are limited to simple jobs; while high-skilled unemployed can apply for both types of jobs, and thereby can accept to be downgraded. We analyze the outcomes of simple job subsidy policies assuming that government budget is balanced through taxes on occupied workers. We first give conditions for the existence and uniqueness of a steady-state equilibrium and we then analyze the effects of different fiscal instruments. We show that in this set-up, increasing simple job subsidies does not necessarily reduce low-skilled unemployment or unemployment spells. By introducing heterogeneous skills and possible downgrading of the high-skilled workers, we show that the effectiveness of such policies in reducing the classical unemployment is decreasing. In fact, any additional classical unemployed re-entering the job market is accompanied by an increasing number of high-skilled workers downgrading to low-skilled jobs. We calibrate the model on French labor market data. It is found that for five low-skilled workers leaving classical unemployment, two high-skilled workers are downgraded.     

Firm-specific wage growth and changes in the labor market for managers

This paper analyzes recent changes in the employment relationships between managers and firms. In both Becker's and Lazear's models of firm-specific wage growth, compensation is deferred from early in an employee's tenure with a firm until later in the contract. The deferred compensation bonds the worker to the firm. Based on cross-sectional data from Current Population Surveys, rates of firm-specific wage growth are estimated for the managerial labor market. The findings show that the rate of wage growth that is firm-specific for managers in manufacturing industries declined significantly during the early 1980s. It is estimated, for example, that a manager with 12 years of tenure in a manufacturing firm enjoyed, on average, a 25% wage premium in 1979 over an otherwise similar manager who was a new hire in a firm. By 1983 the firm-specific wage premium for a manager with 12 years of tenure was only 5%. These changes represent a significant reduction in the strength of the employment bond between firms and managers, and a reduction in the incentive effects previously enjoyed by firms from the use of deferred-compensation schemes. This change is consistent with the significant increases in the displacement rates of managers that occurred during the 1980s.     

The part-time pay penalty in a segmented labor market

This paper is the first to examine the implications of switching to PT work for women's subsequent earnings trajectories, distinguishing by their type of contract: permanent or fixed-term. Using a rich longitudinal Spanish data set from Social Security records of over 76,000 prime-aged women strongly attached to the Spanish labor market, we find that the PT/FT hourly wage differential is larger and more persistent among fixed-term contract workers, strengthening the existent evidence that these workers can be classified as secondary. The paper discusses problems arising in empirical estimation (including a problem not discussed in the literature up to now: the differential measurement error of the LHS variable by PT status), and how to address them. It concludes with policy implications relevant for Continental Europe and its dual structure of employment protection.     

Housing tenure and labor market impacts: The search goes on

We develop two search-theoretic models emphasizing firm entry to examine the Oswald hypothesis, the idea that homeownership is linked to inferior labor market outcomes, and compare their predictions to three extant theories. The five models have surprisingly different predictions about the labor market at both the aggregate and micro levels. Using a suitable instrumental variable strategy, we estimate both micro and aggregate level regression models of wages and unemployment and compare the estimates to those predictions. We find that while homeowners are less likely to be unemployed, they also have lower wages, all else equal, compared to renters. In addition, higher regional homeownership rates are associated with a greater probability of individual worker unemployment and higher wages. The outcome of a horserace between our new search-theoretic models is mixed—the wage-posting model predicts observed unemployment impacts while a bargaining variant does a better job explaining observed wages and aggregate labor market outcomes. Overall, we conclude that firm behavior is important for understanding the labor market impacts of homeownership. Because this is the case, regional homeownership rates are not good instruments for individual tenure choice in empirical work. And while individual homeowners may have inferior labor market outcomes as compared to renters, from the viewpoint of society, higher homeownership rates may result in greater job creation and overall production, among other benefits.     

Analyzing the labor market activity of immigrant families in Germany

This paper analyzes whether immigrant families facing credit constraints adopt a family investment strategy wherein, upon arrival, an immigrant spouse invests in host country-specific human capital while the other partner works to finance the family's current consumption and the spouse's skills accumulation. Using data for West Germany, we do not find evidence for such a specialization strategy. We further examine the labor supply and wage assimilation of families whose members immigrated together relative to families whose members immigrated sequentially. Our estimates indicate that this differentiation is relevant for the analysis of the labor market activities of migrant households.     

An empirical assessment of assortative matching in the labor market

In labor markets with worker and firm heterogeneity, the matching between firms and workers may be assortative, meaning that the most productive workers and firms team up. We investigate this with longitudinal population-wide matched employer–employee data from Portugal. Using panel data methods, we quantify a firm-specific productivity term for each firm, and we relate this to the skill distribution of workers in the firm. We find that there is positive assortative matching, in particular among long-lived firms. Using skill-specific estimates of an index of search frictions, we find that the results can only to a small extent be explained by heterogeneity of search frictions across worker skill groups.
