Search frictions and labor market participation

Cross-country differences in labor market participation are often larger than differences in unemployment rates. The same holds true across demographic groups within a given economy. We argue that the interaction between labor force participation decisions and labor market frictions can help us understand these patterns. This interaction highlights dynamic aspects of the participation decision, in contrast to standard textbook treatments that emphasize static costs and benefits of participation. We extend the standard labor market search problem to allow for a third state—non-participation—and assumes that stochastic participation costs precipitate flows into and out of non-participation. We fully characterize the worker's decision problem and use numerical simulations to demonstrate how participation patterns vary with individual characteristics and with labor market conditions.     

Labor search and matching in macroeconomics

The labor search and matching model plays a growing role in macroeconomic analysis. This paper provides a critical, selective survey of the literature. Four fundamental questions are explored: How are unemployment, job vacancies, and employment determined as equilibrium phenomena? What determines worker flows and transition rates from one labor market state to another? How are wages determined? What role do labor market dynamics play in explaining business cycles and growth? The survey describes the basic model, reviews its theoretical extensions, and discusses its empirical applications in macroeconomics.The model has been developed against the background of difficulties with the use of the neo-classical, frictionless model of the labor market in macroeconomics. Its success includes the modelling of labor market outcomes as equilibrium phenomena, the reasonable fit of the data, and—when inserted into business cycle models—improved performance of more general macroeconomic models. At the same time, there is evidence against the Nash solution used for wage setting and an active debate as to the ability of the model to account for some of the cyclical facts.     

Caste discrimination and transaction costs in the labor market: Evidence from rural North India

This paper is an empirical attempt to quantify caste-based discrimination in the labor market using household data taken from rural North India. In the regression analysis, transaction costs associated with entry into the labor market and reservation wages are estimated simultaneously along with market wages. The estimation results provide evidence of the existence of transaction costs in the labor market and discrimination against backward classes with regard to access to regular employment. In line with previous studies, the results suggest that the achievements of India's reservation policy so far have at best been limited. In addition, a comparison between the estimates from the model employed in this paper and conventional (reduced-form) approaches shows that discrimination in labor market entry is likely to be underestimated in the conventional reduced-form approaches.     

Job search and academic achievement

The paper develops a structural model for the labor market behavior of students entering the labor market. We explicitly model the trade-off between devoting effort to studying and to job search. Furthermore, we allow for on-the-job search. The model is estimated using a unique data set of individuals who completed undergraduate education in the Netherlands between 1995 and 2001. Our estimation results show that labor market returns of high grades are low. Wage increases between jobs are explained by labor market friction rather than returns of early work experience. Our results indicate that a 1 percentage point decrease in the unemployment rate increases wage offers on average by 3 percent, but that the amount of job search effort is not very sensitive to business cycle fluctuations. Policy simulations show that study effort and hence academic achievement are much more sensitive to financial incentives than job search effort and labor market outcomes.     

Termination of dynamic contracts in an equilibrium labor market model

In an equilibrium model of the labor market, workers and firms enter into dynamic contracts that can potentially last forever, but are subject to optimal terminations. Upon termination, the firm hires a new worker, and the worker who is terminated receives a termination contract from the firm and is then free to go back to the labor market to seek new employment opportunities and enter into new dynamic contracts. The model permits only two types of equilibrium terminations that resemble, respectively, the two kinds of labor market separations that are typically observed in practice: involuntary layoffs and voluntary retirements. The model allows for the simultaneous determination of a large set of important labor market variables including equilibrium unemployment and labor force participation. An algorithm is formulated for computing the model's equilibria. I then simulate the model to show quantitatively that the model is consistent with a set of important stylized facts of the labor market.     

The dynamic impact of immigration on natives' labor market outcomes: Evidence from Israel

This paper studies the short and medium run impact of highly skilled immigrants from the Former Soviet Union to Israel on natives' wages and employment. If immigrants are relatively good substitutes for native workers, the impact of immigration will be largest immediately upon the immigrants' arrival, and may become smaller as the labor market adjusts to the supply shock. Conversely, if immigrants upon arrival are poor substitutes for natives, the initial effect of immigration is small, and increases over time as immigrants acquire local labor market skills and compete with native workers. We empirically examine these alternative hypotheses using data from Israel between 1989 and 1999.We find that wages of both men and women are negatively correlated with the fraction of immigrants with little local experience in a labor market segment. A 10 percent increase in the share of immigrants lowers natives' wages in the short run by 1–3 percent, but this effect dissolves after 4–7 years. This result is robust to a variety of different segmentations of the labor market, to the inclusion of cohort effects, and to different dynamic structures in the residual term of the wage equation. On the other hand, we do not find any effect of immigration on employment, neither in the short nor in the medium run.     

Are judges biased by labor market conditions?

When a firing litigation is taken to court, only the characteristics of the employee's misconduct should be relevant for the judge's decision. Using detailed data from an Italian bank and aggregate macro data, this paper shows that, instead, local labor market conditions influence the court's decision: The same misconduct episode may be considered sufficient for firing in a tight labor market but insufficient otherwise. We reach this conclusion after taking carefully into consideration the non-random selection of firing litigations for trial. Although these results refer to the specific situation considered, they raise more general issues. For macroeconomists they suggest that higher unemployment rates may increase firing costs via the effect on courts’ decision criteria; thus, the real extent of firing rigidities cannot be assessed without considering the role of courts. For labor law scholars, these findings are important because, following traditional principles, the law should be applied in the same way for all citizens and over the entire national territory.     

The labor market and corporate structure

We analyze the impact of labor demand and labor market regulations on the corporate structure of firms. Higher wages are associated with lower monitoring, irrespective of whether these high wages are caused by labor market regulations, unions or higher labor demand. We also find that the organization of firms has important macroeconomic implications. In particular, monitoring is a type of “rent-seeking” activity and the decentralized equilibrium spends excessive resources on monitoring. Labor market regulations that reduce monitoring by pushing wages up may increase net output or reduce it only by a small amount even though they reduce employment.     

Unemployment Invariance

Abstract. This paper provides a critique of the ‘unemployment invariance hypothesis’, according to which the behavior of the labor market, by itself, ensures that the long‐run unemployment rate is independent of the size of the capital stock, productivity and the labor force. In the context of an endogenous growth model, we show that the labor market alone need not contain all the equilibrating mechanisms to ensure unemployment invariance; in particular, other markets may perform part of the equilibrating process as well. By implication, policies that raise the growth path of capital or increase the effective working‐age population may influence the long‐run unemployment rate.     

The consequences of labor market flexibility: Panel evidence based on survey data

We introduce a new data set on hiring and firing restrictions for 21 OECD countries for the period 1984-1990. The data are based on surveys of business people in the countries covered, so the indices we use are subjective in nature. Controlling for country and time fixed effects, and using dynamic panel data techniques, we find evidence that increasing the flexibility of the labor market increases both the employment rate and the rate of participation in the labor force. A conservative estimate suggests that if France were to make its labor markets as flexible as those in the US, its employment rate would increase 1.6 percentage points, or 14% of the employment gap between the two countries. The estimated effects are larger in the female than in the male labor market, although both groups seem to have similar long-run coefficients. There is also some evidence that more flexibility leads to lower unemployment rates and to lower rates of long-term unemployment. We also find evidence consistent with the hypothesis that inflexible labor markets produce “jobless recoveries” and introduce more unemployment persistence.     

Tenure, business cycle and the wage-setting process

We analyze the interaction between job tenure and external labor market conditions in wage determination. First, we introduce a model that combines job matching with business-cycle effects. As the employment relationship progresses, the worker appropriates a portion of the value of the match-specific human capital she accumulates, gradually becoming shielded from the cyclical variations in external labor market conditions: the employment relationship is progressively “internalized”. Then, we present empirical evidence supporting this prediction: the elasticity of wages to the unemployment rate decreases with tenure. This finding is robust to different specifications that allow for job heterogeneity, and it contributes to the interpretation of recent evidence of changes in the effect of the business cycle on wages.     

Industry structure and labor market flexibility in the South African manufacturing sector: A time series and panel data approach

This paper presents a joint analysis of labor market flexibility and product market structure. Our investigation confirms earlier results of imperfect competition in South African manufacturing where we find an average mark-up of 50% for the period 1970 to 2004 that is without consistent trend over time. The contribution of the paper is to provide a theoretically grounded means of linking output market conduct to labor market flexibility. We infer the proportion of labor associated with rigidities in the labor market from the mark-up, and find that two thirds of total labor employed in South African manufacturing is associated with rigidities. We find that this proportion falls during the 1980s and rises during the 1990s, suggesting an increase in labor flexibility followed by a decrease.     

Networks in labor markets: Wage and employment dynamics and inequality

We present a model of labor markets that accounts for the social network through which agents hear about jobs. We show that both wages and employment are positively associated (a strong form of correlation) across time and agents. We also analyze the decisions of agents regarding staying in the labor market or dropping out. If there are costs to staying in the labor market, then networks of agents that start with a worse wage status will have higher drop-out rates and there will be a persistent differences in wages between groups according to the starting states of their networks.     

The Labor Contract Law,Macro Conditions,Self‐Selection,and Labor Market Outcomes for Migrants in China

China introduced a new Labor Contract Law (LCL, 2008) to protect employees’ working conditions and welfare. Early evaluations of labour market outcomes suggest positive effects for workers. In the same period, however, China faced labor market tightening, which facilitated the LCL's introduction and enforcement. Existing evaluations of the LCL treat the introduction of the LCL as being exogenous. We show that labor market tightening and individuals’ self‐selection into jobs whichcomply with the Law have affected migrant labor market outcomes. Taking these factors separately into account suggests that, the LCL has had varying effects on labor market outcomes: a negative effect on wages and hours; an unclear effect on having a written contract, and a positive effect on social insurance participation. Data inadequacies prevent us from considering these factors simultaneously.     

Evolution of Female Labor Force Participation in the United States: 1967 to 2003

This paper describes the changes in the employment choices of prime working-age women from 1967 to 2003. A neoclassical labor market participation model is presented and applied to data from the March Current Population Surveys (CPS). The paper provides a new insight: It highlights the different patterns of labor force participation by family-status categories. Also, the paper introduces the average annual unemployment rate at the state level as an explanatory variable to capture the demand-side constraint of the labor market. The results of the paper support the finding that since 1990, the increase in the participation of women in the labor force has slowed from previous decades.An earlier draft of this paper was presented at the 59th International Atlantic Economic Conference, London, England, March 9–13, 2005.     

A three state model of worker flows in general equilibrium

We develop a simple model featuring search frictions and a nondegenerate labor supply decision along the extensive margin. The model is a standard version of the neoclassical growth model with indivisible labor and idiosyncratic productivity shocks and frictions characterized by employment loss and employment opportunity arrival shocks. We argue that it is able to account for the key features of observed labor market flows for reasonable parameter values. Persistent idiosyncratic productivity shocks play a key role in allowing the model to match the persistence of the employment and out of the labor force states found in individual labor market histories.     

Globalization and labor market institutions: International empirical evidence

A widespread concern is that labor market institutions erode in the course of globalization, which, in turn, decreases employment and wages. By using panel data and cross-sectional data, I investigate the influence of globalization on labor market regulation. I use the indicators of labor market institutions by Gwartney et al. (2012) and the KOF indices of globalization. To deal with potential reverse causality, I employ a system GMM panel estimator and use a constructed trade share as proposed by Frankel and Romer (1999) as an instrumental variable for globalization in cross-sectional models. The results do not show that globalization induced labor market deregulation.     

Labor market reform and incidence of child labor in a developing economy

The paper is purported to examine the consequences of possible labor market reform in the developing economies on the incidence of child labor and economic well-being of the child labor supplying families. A two-sector, full-employment general equilibrium structure with child labor and imperfection in the market for adult labor has been used for the analytical purpose. Although this policy is likely to lower the incidence of child labor the welfare of the families supplying child labor worsens. The paper, therefore, questions the desirability of a policy designed at mitigating the child labor problem especially when it makes the poor families worse off.     

The effect of working time and labor force participation on unemployment: A new argument in an old debate

This paper introduces a new argument into the theoretical literature on labor market effects of changes in working hours and labor force participation. We advance a general equilibrium model in which increased labor supply reduces unskilled unemployment via consumer demand: longer work hours and higher labor force participation imply higher incomes and less (leisure) time. In consequence, home production is reduced in favor of outsourcing domestic tasks to the market, shifting consumer demand toward unskill-intensive goods. Relative demand for unskilled labor rises and unemployment falls.
