The long-term effects of job search requirements: Evidence from the UK JSA reform

This paper investigates long-term returns from unemployment compensation, exploiting variation from the UK JSA reform of 1996, which implied a major increase in job search requirements for eligibility and in the related administrative hurdle. Search theory predicts that such changes should raise the proportion of nonclaimant nonemployed, with consequences on search effort and labor market attachment, and lower the reservation wage of the unemployed, with negative effects on post-unemployment wages. I test these ideas on longitudinal data from social security records (LLMDB). Using a difference in differences approach, I find that individuals who start an unemployment spell soon after JSA introduction, as opposed to 6 months earlier, are 2.5–3% more likely to move from unemployment into Incapacity Benefits spells, and 4–5% less likely to have positive earnings in the following year. This latter employment effect only vanishes 4 years after the initial unemployment shock. Also, annual earnings for the treated individuals are lower than for the non-treated. These results suggest that while tighter search requirements were successful in moving individuals off unemployment benefits, they were not successful in moving them onto stable or better jobs, with fairly long-lasting unintended consequences on a number of labor market outcomes.     

Optimal Welfare-to-Work Programs

A Welfare-to-Work (WTW) program is a mix of government expenditures on various labour market policies targeted to the unemployed ( e.g. unemployment insurance (UI), job search monitoring (JM), social assistance (SA), wage subsidies). This paper provides a dynamic principal–agent framework suitable for analysing chief features of an optimal WTW program, such as the sequence and duration of the different policies, the dynamic pattern of payments along the unemployment spell, and the emergence of taxes/subsidies upon re-employment. The optimal program endogenously generates an absorbing policy of last resort ("social assistance") characterized by a constant lifetime payment and no active participation by the agent. Human capital depreciation is a necessary condition for policy transitions to be part of an optimal WTW program. The typical sequence of policies is quite simple: the program starts with standard UI, then switches into monitored search and, finally, into SA. The optimal benefits are decreasing during unemployment insurance and constant during both JM and SA. Whereas taxes (subsidies) can be either increasing or decreasing with duration during UI, they must decrease (increase) during a phase of JM. In a calibration exercise, we use our model to analyse quantitatively the features of the optimal program for the U.S. economy. With respect to the existing U.S. system, the optimal WTW scheme delivers sizeable welfare gains to unskilled workers because the incentives to search for a job can be retained even while delivering more insurance and using costly monitoring less intensively.     

OPTIMAL UNEMPLOYMENT INSURANCE,WITH HUMAN CAPITAL DEPRECIATION,AND DURATION DEPENDENCE*

This article introduces the possibility of a deterioration in job opportunities during unemployment into the standard optimal unemployment insurance (UI) design framework and characterizes the efficient UI scheme. The optimal program may display two novel features, which cannot be present in stationary models. First, UI transfers are bounded below by a minimal assistance level that arises endogenously in the efficient contract. Second, the optimal scheme implies a wage subsidy for long‐term unemployed workers. Numerical simulations based on the Spanish and U.S. economies suggest that both assistance transfers and wage subsidies should be part of the UI scheme in these countries.     

Unobserved Heterogeneity,Exit Rates,and Re‐Employment Wages

Exit rates from unemployment and re‐employment wages decline over a period of unemployment, after controlling for worker observable characteristics. We study the role of unobserved heterogeneity in an economy with asymmetric information and directed search. We show that the unique equilibrium is separating and that skilled workers have more job opportunities and higher wages. The composition of the unemployed varies with the duration of unemployment, so average exit rates and wages fall with time. The separating equilibrium relies on performance‐related pay schemes and the ability of firms to commit to renting an input that is complementary to worker skills.     

Optimal Workfare with Voluntary and Involuntary Unemployment*

This paper addresses the welfare implications of introducing workfare into unemployment benefit policy. We consider a population composed of employed and unemployed workers and of individuals who do not seek employment. Job search behavior is unobservable, which means that voluntarily unemployed individuals can claim unemployment insurance (UI) benefits intended for unemployed workers. As a consequence, pecuniary benefit schemes underinsure workers against unemployment. We show that requiring unproductive activities (workfare) in exchange for UI benefits may generate a Pareto improvement by facilitating better unemployment insurance for workers, and we characterize the situations where this is the case.     

The Effects of Marginal Employment on Subsequent Labour Market Outcomes

Abstract. Unemployed workers in Austria do not lose their unemployment benefits (UI) if they work in a job where their earnings are below a certain threshold [‘marginal employment’ (ME)]. ME might improve their labour market status by signalling effort, or worsen it through reduced job‐search effort. Those who work in ME while claiming UI have less employment and lower earnings afterwards than those who do not. The penalty lessens over time but is still present after three years.     

Unemployment insurance,recalls, and experience rating

In the United States, almost half of the workers who separated from their jobs ended their unemployment spell by returning to work for their last employer. In this study, we explore the impact of the experience rating (ER) system on recalls. In states using reserve ratio ER, and for a firm that is not at the minimum or the maximum tax rate, each layoff of a worker receiving unemployment benefits increases the future tax rate while each recall reduces it. This provides a natural incentive for firms to recall former workers receiving unemployment benefits. We use the Quarterly Workforce Indicators dataset, which provides information on recalls at the county level, and exploit the differences in tax schedule across states to estimate the impact of ER on recalls. We show that the recall share from hires increases with the degree of ER. We then develop a search and matching model with different unemployment insurance (UI) status, endogenous UI take-up, endogenous separations, recalls, and new hires. We illustrate that this model reproduces the effects of ER on recalls admirably. We show that an increase in the intensity of ER translates into a higher recall share at the steady state, especially for unemployed workers collecting unemployment benefits. We then use this model to analyze the labor market dynamics under alternative financing schemes. We show that ER has stabilization virtues—the higher the degree of ER, the less volatile the unemployment rate.     

The Nature of Unemployment among Young Men in Urban Ethiopia

This paper investigates the nature of unemployment among young men in urban Ethiopia and finds that it is concentrated among relatively well‐educated first‐time job seekers who aspire to a public sector job and spend on average close to four years in unemployment. This is consistent with a segmented labor market model where youngsters queue in unemployment for a good job, as confirmed by an empirical test of the theoretical prediction. We observe a negative (causal) relationship between household welfare and both the incidence and duration of unemployment, indicating that unemployment is concentrated among the relatively worse off urban households, which from a national perspective represent the middle classes, and find suggestive evidence that part of this effect is due to malnutrition during childhood. Job search through social networks is only effective after one has become unemployed, suggesting that networks provide insurance only after exposure to the risk.     

Does the public employment service affect search effort and outcomes?

In this paper, we examine the disincentive effects of the public employment service on the search effort of unemployed workers and on their exit rate from unemployment. For that purpose, we specify a structural search model with fixed and variable costs of search in which unemployed workers select their optimal search intensity given the exogenous arrival rate of job contacts coming from the public employment agency. Because the theoretical effect of an increase in this exogenous job contact arrival rate on the structural exit rate from unemployment is ambiguous, we estimate this model using individual unemployment duration data. Our results show that the exit rate from unemployment increases with the arrival rate of job contacts obtained by the public employment service, especially for low-educated and low-skilled workers. They also show that the search effort is more costly for low-educated women and low-skilled adult unemployed workers. This last result suggests that a public employment agency that matches searchers and employers is beneficial, in the sense that it saves searchers in terms of search costs they would otherwise bear.     

Labor force participation and the discouraged worker effect

This article analyzes labor force participation with particular reference to the discouraged worker effect. Discouraged workers are those who will search for work when the labor market is tight but do not search for work when the labor market is slack because they consider their chances of finding a suitable job too low. The theoretical point of departure is a search model where the worker evaluates the expected utility of searching for work and decides to participate in the labor market if the expected utility of search exceeds the utility of not working. From this framework, we derive an empirical model for the probability that the worker will be out of the labor force, unemployed, or employed. The model is estimated on a sample of married and cohabitating women in Norway covering the period from 1988 to 2008. The results show that the discouraged worker effect is substantial. On average, about one-third of those who are out of the labor force are discouraged, according to our analysis.     

Optimal unemployment insurance in an estimated job search model with savings

This paper estimates a job search model with savings on Danish micro data that include observations on wealth and wages. Controlling for extensive observed and unobserved worker characteristics heterogeneity, the estimation relates observed unemployment spells to the model implied hazard rate for each worker. The model estimates are sensible and fit the data well. Optimal UI policy is determined in the estimated model as a trade-off between insurance provision and distortion of search incentives. The analysis emphasizes an important policy sensitivity to the interest rate and the importance of including transitional dynamics in the analysis.     

Search costs and efficiency: Do unemployed workers search enough?

Many labor market policies affect the marginal benefits and costs of job search. The impact and desirability of such policies depend on the distribution of search costs. In this paper, we provide an equilibrium framework for identifying the distribution of search costs and we apply it to the Dutch labor market. In our model, the wage distribution, job search intensities, and firm entry are simultaneously determined in market equilibrium. Given the distribution of search intensities (which we directly observe), we calibrate the search cost distribution and the flow value of non-market time; these values are then used to derive the socially optimal firm entry rates and distribution of job search intensities. From a social point of view, some unemployed workers search too little due to a hold-up problem, while other unemployed workers search too much due to coordination frictions and rent-seeking behavior. Our results indicate that jointly increasing unemployment benefits and the sanctions for unemployed workers who do not search at all can be welfare-improving.     

The costs of hiring skilled workers

This paper analyzes the structure of hiring costs for skilled workers. We use novel Swiss administrative firm-level survey data that provide direct and detailed measures of hiring costs, including recruitment and adaptation. Results show that average hiring costs range, depending on firm size, from 10 to 17 weeks of wage payments. The structure of hiring costs is convex. Marginal hiring costs increase with the number of hires and reach up to 24 weeks of wage payments. We find no evidence for a fixed cost component. Hiring costs also increase with the hiring rate (the ratio of hires and skilled workers), confirming convexity. Hiring costs generally increase with skill requirements for job applicants, and depend on macroeconomic conditions: a 1% point increase in the unemployment rate reduces average hiring costs by more than 5%.     

Job search,wage offers,and unemployment insurance

Several previous studies have estimated that unemployment insurance (UI) causes an increase in the duration of unemployment and have concluded from this that UI raises reservation wages. However, job-search theory implies that UI can also affect duration through its impact on job offer arrival rates and/or through an impact on wage offers. In this paper we attempt to identify these possible additional effects using survey data on a sample of unemployed individuals. Like previous studies, we find that UI significantly increases unemployment duration. However, part of this effect is estimated to stem from a decrease in the offer arrival rate as well as from a higher reservation wage.     

Reassessing the ins and outs of unemployment

This paper uses readily accessible aggregate time series to measure the probability that an employed worker becomes unemployed and the probability that an unemployed worker finds a job, the ins and outs of unemployment. Since 1948, the job finding probability has accounted for three-quarters of the fluctuations in the unemployment rate in the United States and the employment exit probability for one-quarter. Fluctuations in the employment exit probability are quantitatively irrelevant during the last two decades. Using the underlying microeconomic data, the paper shows that these results are not due to compositional changes in the pool of searching workers, nor are they due to movements of workers in and out of the labor force. These results contradict the conventional wisdom that has guided the development of macroeconomic models of the labor market since 1990.     

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.     

Minimum wages and youth unemployment

This paper constructs a labor search model to explore the effects of minimum wages on youth unemployment. To capture the gradual decline in unemployment for young workers as they age, the standard search model is extended so that workers gain experience when employed. Experienced workers have higher average productivity and lower job finding and separation rates that match wage and worker flow data. In this environment, minimum wages can have large effects on unemployment because they interact with a worker's ability to gain job experience. The increase in minimum wages between 2007 and 2009 can account for a 0.8 percentage point increase in the steady state unemployment rate and a 2.8 percentage point increase in unemployment for 15–24 year old workers in the model parameterized to simulate outcomes of high school educated workers. Minimum wages can also help explain the high rates of youth unemployment in France compared to the United States.     

Running out of time: Limited unemployment benefits and reservation wages

We study unemployment insurance (UI) in an equilibrium environment in which unemployed workers only receive benefits for a finite length of time. Although all workers have identical productivity and leisure value, the random arrival of job offers creates ex-post differences with respect to their time remaining until benefit expiration. Firms, which are also homogeneous, can exploit these differences, leading to an endogenous wage distribution.This allows us to examine the equilibrium effect of policy changes in both the size and length of UI benefits. Surprisingly, an increase in benefits can actually cause wages to fall, which is contrary to the predictions of on-the-job-search models. Moreover, we explain well-documented patterns of how the hazard rate of exiting unemployment responds to these policy changes. Our theory also explains why this hazard rate jumps at the time of benefit exhaustion.     

Revisiting the welfare effects of eliminating business cycles

We investigate the welfare effects of eliminating business cycles in a model with substantial consumer heterogeneity. The heterogeneity arises from uninsurable and idiosyncratic uncertainty in preferences and employment status. We calibrate the model to match the distribution of wealth in U.S. data and features of transitions between employment and unemployment. In comparison with much of the literature, we find rather large effects. For our benchmark model, we find welfare effects that, on average across all consumers, are of a bit more than one order of magnitude larger than those computed by Lucas [Lucas Jr., R.E., 1987. Models of Business Cycles. Basil Blackwell, New York]. When we distinguish long- from short-term unemployment, long-term unemployment being distinguished by poor (and highly procyclical) employment prospects and low unemployment compensation, the average gain from eliminating cycles is as much as 1% in consumption equivalents. In addition, in both models, there are large differences across groups: very poor consumers gain a lot when cycles are removed (the long-term unemployed as much as around 30%), as do very rich consumers, whereas the majority of consumers—the “middle class”—sees much smaller gains from removing cycles. Inequality also rises substantially upon removing cycles.     

RESIDUAL WAGE DISPARITY AND COORDINATION UNEMPLOYMENT*

How much of residual wage dispersion can be explained by an absence of coordination among firms? To answer, we construct a dynamic directed search model with identical workers where firms can create high‐ or low‐productivity jobs and are uncoordinated in their offers to workers, calibrated to the U.S. economy. Workers can exploit ex post opportunities once approached by firms, and can conduct on‐the‐job search. The stationary equilibrium wage distribution is hump‐shaped, skewed significantly to the right, and, with baseline parameters, generates residual dispersion statistics 75–90% of those found empirically. However, the model underestimates the average duration of unemployment.
