Discrimination and Skill Differences in an Equilibrium Search Model*

We analyze an equilibrium search model with three sources for wage and unemployment differentials among workers with the same (observed) human capital but different appearance (race): unobserved productivity, search intensities, and discrimination due to an appearance‐based employer disutility factor. We show that the structural parameters are identified using labor market survey data. Estimation results for a black and white high school graduate sample imply: black productivity is 3.3% lower than white productivity; the employer's disutility factor is 31% of the white's productivity level; and 56% of firms have a disutility factor toward blacks.     

HAPPY PEOPLE ARE LESS LIKELY TO BE UNEMPLOYED: PSYCHOLOGICAL EVIDENCE FROM PANEL DATA

There is a large literature showing that unemployment reduces people's well‐being. Yet little is known about the reverse possibility, namely that well‐being itself may influence unemployment propensity. Understanding the potentials of human well‐being in relation to unemployment is important as many developed countries are currently facing high unemployment rates. As well‐being is likely to be endogenous, we use British panel data and implement Lewbel's novel empirical approach for identification. We show that higher well‐being implies a negative causal effect on the probability of being unemployed. The result holds for two very different well‐being measures: life satisfaction and a 12‐item scale of mental health. As such, it provides new empirical evidence on the causal link between well‐being and unemployment propensity. (JEL D03, I31)     

ROLLING REGRESSION VERSUS TIME‐VARYING COEFFICIENT MODELLING: AN EMPIRICAL INVESTIGATION OF THE OKUN'S LAW IN SOME EURO AREA COUNTRIES

During the last decade, economists have shown that the inverse relationship between economic growth and unemployment rate varies over time. Rolling regression has been the main tool used to quantify such a relationship. This methodology suffers from several well‐known problems which lead to spurious non‐linear patterns in the Okun's coefficient behaviour over time. Here, we take a penalized regression spline approach to estimate the Okun's time‐varying effects. As a result, spurious non‐linearities are suppressed and hence important time‐varying coefficient features revealed. Our empirical results show that the inverse relationship in some Euro area countries is spatially heterogeneous and time‐varying. The findings are complemented by the calculation of the rate of output growth needed for a stable unemployment rate, as proposed by Knotek.     

A TEST OF EMPLOYER DISCRIMINATION IN THE NBA

This paper presents a test of an important implication of Becker's theory of employer discrimination: when institutional change enhances labor mobility, employer discrimination falls because it becomes more costly for employers to indulge tastes for discrimination. The test case is the National Basketball Association (NBA). This paper specifically addresses the following question about the NBA: why did black/white player salary differentials vanish by the early 1990s? Previous studies claim that NBA wage gaps in the 1980s are attributable to customer discrimination and monopsonistic wage discrimination. This study argues that employer discrimination was an important source of those gaps and that one reason they vanished was because reduced monopsony power eradicated employer discrimination. Monopsony power fell because the 1988 NBA Collective Bargaining Agreement and the entry of four new teams in the league enhanced player mobility and increased the amount of labor market competition. Using data for the 1985-86 and 1990-91 seasons, employer discrimination was proxied by the race of the team's general manager. Empirical results strongly suggest that a major reason the NBA wage gap vanished in the later period was because of a reduction in employers' ability to discriminate. This is in contrast to earlier literature on the NBA, which has tended to emphasize the role of customer discrimination. (JEL J71)     

Discrimination and the unemployment durations of white and black males

In this study we develop a model to decompose the longer unemployment duration of blacks into discriminatory and non-discriminatory components. By extending Becker's theory of discrimination to job-search theory, the discriminatory component is seen to be the result of two separate effects. First, a white treatment advantage shortens the unemployment duration of whites because they receive more frequent and higher wage offers than would prevail in the absence of discrimination for working alongside blacks. Second, a black treatment disadvantage lengthens the jobless spell of blacks because blacks receive lower wage offers than would prevail without discrimination as discriminating employers extract quasi-rents from their labour. We estimate our model using date from the CPS Displaced Workers Survey. The results show that 3.81 of the 4.58 weeks longer unemployment spell for blacks is due to discrimination, with 3.11 weeks resulting from the white treatment advantage, and 0.7 weeks emanating from the black treatment disadvantage.     

Interregional Migration of Human Capital and Unemployment Dynamics: Evidence from Italian Provinces

Since the mid‐1990s interregional migration flows in Italy have dramatically increased, especially from the South to the North. These flows are characterized by a strong component of human capital, involving a large number of workers with secondary and tertiary education. Using longitudinal data for the period 2002–2011 at NUTS‐3 territorial level, we document that long‐distance (i.e., South‐North) net migration of high‐skill workers has increased the unemployment at origin and decreased it at destination, thus deepening North–South unemployment disparities. On the other hand, long‐distance net migration of low‐skill workers has had the opposite effect, by lowering the unemployment at origin and raising it at destination. Further evidence also suggests that the diverging effect of high‐skill migration dominates the converging effect of low‐skill migration. Thus, concerns for an ‘internal brain drain’ from Southern regions look not groundless.     

Unemployment Responses to 'Skill-biased' Technology Shocks: the Role of Labour Market Policy

Do skill-biased shocks that increase the spread of labour productivities, interacting with different policy regimes, explain the rise in unemployment in Europe relative to the United States in the 1980s and 1990s? The hypothesis is an implication of a version of the Mortensen and Pissarides (1994) model of equilibrium unemployment which allows for worker heterogeneity. A calibrated version of the model implies that a similar unemployment increase would have occurred in the United States over this period, given changes in relative productivity by education implied by observed wage changes, had unemployment compensation and employment protection policies been at European levels.     

STRUCTURAL EMPIRICAL EVALUATION OF JOB SEARCH MONITORING

To evaluate search effort monitoring of unemployed workers, it is important to take account of post‐unemployment wages and job‐to‐job mobility. We structurally estimate a model with search channels, using a controlled trial in which monitoring is randomized. The data include registers and survey data on search behavior. We find that the opportunity to move to better‐paid jobs in employment reduces the extent to which monitoring induces substitution toward formal search channels in unemployment. Job mobility compensates for adverse long‐run effects of monitoring on wages. We examine counterfactual policies against moral hazard, like reemployment bonuses and changes of the benefits path.     

An Evaluation of Inertia Models of Unemployment

Two approaches have been used to model unemployment. The first, conventional, approach involves linking the unemployment outcome to observed indices of productivity, structural factors and discrimination such as educational attainment, location and birthplace. The second approach, the inertia model, involves using a person's labour market history as a way of including in unemployment models information on the 'unobservables' that influence employability. This paper evaluates the performance of both models of unemployment. The results provide unambiguous support for the inertia model when modelling unemployment. The inertia model has higher explanatory power, higher within-sample prediction rate success and fewer out-of-sample forecasting errors than the conventional model. The estimates from the inertia model can be used to provide quite accurate predictions of the risk of becoming unemployed. This is important if individuals at high risk of becoming unemployed are to be targeted for labour market assistance.     

Understanding South Africa's economic puzzles*

South Africa has undergone a remarkable transformation since its democratic transition in 1994, but economic growth and employment generation have been disappointing. Most worryingly, unemployment is currently among the highest in the world. While the proximate cause of high unemployment is that prevailing wages levels are too high, the deeper cause lies elsewhere, and is intimately connected to the inability of the South African to generate much growth momentum in the past decade. High unemployment and low growth are both ultimately the result of the shrinkage of the non‐mineral tradable sector since the early‐1990s. The weakness in particular of export‐oriented manufacturing has deprived South Africa of growth opportunities as well as of job creation at the relatively low end of the skill distribution. Econometric analysis identifies the decline in the relative profitability of manufacturing in the 1990s as the most important contributor to the lack of vitality in that sector.     

Trade‐Induced Unemployment: How Much Do We Care?

It is a common perception that a government, especially in the face of elections, is particularly sensitive to the presence of trade‐induced unemployment. In this paper, I ask: how much weight does the incumbent politician actually attach to unemployment resulting from trade? To answer, I build a model that captures government's sympathy to trade‐affected workers and allows me to decompose the channels through which trade‐induced unemployment affects the level of sectoral protection chosen by a politically‐driven incumbent official. I provide empirical evidence that the US government is very sensitive to the presence and the magnitude of trade‐induced unemployment. Specifically, I estimate the weight that the office holder attaches to the welfare of trade‐affected workers to be positive, significant, and four times larger than the weight on the welfare of those who are not affected by trade.     

The Dynamics of Technological Unemployment*

This article compares the short‐ and long‐run effects of technological progress on employment. It presents a simple model of frictional unemployment capturing the negative creative destruction effects of technological change on employment. In the long run, faster technological change accelerates job obsolescence, which reduces the equilibrium level of employment. But it is also shown to have short‐run positive and potentially important effects on employment. This tends to partially reconcile the ‘‘Schumpeterian'’ view of the effects of technological change on labor markets with facts such as the response of most OECD unemployment rates to the 1970s productivity slowdown.     

Whose Job Goes Abroad? International Outsourcing and Individual Job Separations

This paper focuses on the adjustment costs of globalisation by studying the effects of international outsourcing on individual transitions out of jobs in the Danish manufacturing sector for the period 1990–2003. A competing risks duration model that distinguishes between job‐to‐job and job‐to‐unemployment transitions is estimated. Outsourcing is found to increase the unemployment risk of low‐skilled workers, but the quantitative impact is modest. Outsourcing is also found to reduce the job change hazard rate for all education groups. Thus, the paper provides evidence for small adjustment costs of globalisation.     

Unemployment Durations in West Germany Before and After the Reform of the Unemployment Compensation System during the 1980s

Abstract. This paper analyzes empirically the distribution of unemployment durations in West Germany during the 1980s and 1990s. It therefore covers periods before and after the changes during the mid‐1980s in the maximum entitlement periods for unemployment benefits for older unemployed. The analysis is based on the IAB employment subsample containing administrative data for about 500,000 individuals. Since these data only partly reveal the unemployment duration in an economic sense, we use a narrow and a wide proxy for unemployment. Our empirical analysis finds significant changes in the distribution of non‐employment durations for older unemployed. At the same time, the distribution of unemployment durations between jobs remained unchanged after the reforms. Our findings clearly show that many firms and workers used the more beneficial laws as a part of early retirement packages. Surprisingly, for those workers who found and accepted a new job, we do not observe a prolongation of their search periods to a sizeable extent.     

HOW HAS THE CRISIS OF 2008–09 AFFECTED SUBJECTIVE WELL‐BEING? EVIDENCE FROM 25 OECD COUNTRIES

This paper uses life satisfaction data of almost 140,000 individuals in 25 OECD countries to study how changes in the rates of GDP growth, unemployment, and inflation during the macroeconomic crisis of 2008–09 have affected subjective well‐being. The relative contributions of the three macroeconomic variables to individuals’ life satisfaction are used to assess how each country performed on balance during the crisis. This approach follows a recent trend of using subjective well‐being data for monitoring economic performance and for policy appraisal. We find that in the countries most strongly affected by the crisis, the effects on an average citizen's well‐being may be of a similar magnitude as the effects of the most serious personal life events. The main driver of these effects is the drop in GDP, whose impact is aggravated by the increase of unemployment. Though the inflation rate went down in several of the countries, the effect was too weak to significantly reduce the negative effect of the changes in GDP and unemployment. The results show that GDP fluctuations are important drivers of subjective well‐being.     

ASSET‐BASED UNEMPLOYMENT INSURANCE*

This article studies a model of consumption, savings, and job search in which a borrowing constraint limits self‐insurance. The government administers the unemployment insurance program that may condition on an individual’s asset position, but not on her efforts of finding a job. To compensate for the impediments to self‐insurance, benefit payments should optimally be set higher at lower wealth levels and peak for borrowing‐constrained individuals with zero liquid funds. A quantitative exercise reveals that the U.S. unemployment insurance program is surprisingly close to optimal for the asset poor, but far too generous for wealthier individuals.     

Long‐Term Unemployment and the Great Recession: Evidence from UK Stocks and Flows

Long‐term unemployment more than doubled during the United Kingdom's Great Recession. Only a small fraction of this persistent increase can be accounted for by the changing composition of unemployment across personal and work history characteristics. Through extending a well‐known stocks‐flows decomposition of labour market fluctuations, the cyclical behaviour of participation flows can account for over two‐thirds of the high level of long‐term unemployment following the financial crisis, especially the procyclical flow from unemployment to inactivity. The pattern of these flows and their changing composition suggest a general shift in the labour force attachment of the unemployed during the downturn.     

HYSTERESIS AND THE NAIRU IN THE EURO AREA

This paper analyses the Nairu in the Euro Area and the influence that hysteresis had on its development. Using the Kalman‐filter technique we find that the Nairu has varied considerably since the early 1970s. The Kalman‐filter technique is applied here using explicit exogenous variables. In order to test for hysteresis, the dependence of the Nairu on actual unemployment and long‐term unemployment is estimated and found to be significant for the Euro Area and Germany, respectively. The existence of hysteresis effects implies the possibility of a long‐run non‐superneutrality of monetary policy.     

Estimation of income elasticities from cross-section data

Using Johnson's decomposition technique, this paper demonstrates that the disappearance of the gap between female and male unemployment rates in the United States during the last decade results partly from a general hiring policy that is favourable to women workers. This conclusion holds for workers in five out of eight occupational subsamples considered. The sign and size of unexplained female - male unemployment rate differential estimated from 1969, 1977 and 1987 CPS data suggest that hiring discrimination against females in the US labour market has declined considerably during the last two decades. The study also supports the earlier finding that the growth of employment in government and in the female dominated service sector, and migration of workers from the South to other regions contribute significantly to the convergence of male and female unemployment rates in the 1980s.     

Introducing Time‐to‐Educate in a Job‐Search Model

Transition patterns from school to work differ considerably across OECD countries. Some countries exhibit high youth unemployment rates, which can be considered an indicator of the difficulty facing young people trying to integrate into the labour market. At the same time, education is a time‐consuming process, and enrolment and dropout decisions depend on expected duration of studies as well as on job prospects with and without completed degrees. One way to model entry into the labour market is by means of job‐search models, where the job arrival hazard is a key parameter in capturing the ease or difficulty in finding a job. Standard models of job search and education assume that skills can be upgraded instantaneously (and mostly in the form of on‐the‐job training) at a fixed cost. This paper models education as a time‐consuming process, a concept which we call time‐to‐educate, during which an individual faces the trade‐off between continuing education and taking up a job.
