Labor market shocks and retirement: Do government programs matter?

This paper argues that labor market conditions are an important and often overlooked determinant of retirement transitions. In our analysis, we examine how the unemployment rate affects retirement and whether the Social Security (SS) system and Unemployment Insurance (UI) system influence how older workers respond to labor market shocks. We use pooled cross-sectional data from the March Current Population Survey (CPS) in our analysis. We find that downturns in the labor market increase retirement transitions and that the magnitude of this effect is comparable to that associated with moderate changes in financial incentives to retire and to the threat of a health shock facing older workers. Interestingly, retirements only increase in response to an economic downturn once workers become SS-eligible, suggesting that retirement benefits may help to alleviate the income loss associated with a weak labor market. We also estimate the impact of UI generosity on retirement and find little consistent evidence of an effect. This suggests that in some ways SS may serve as a more effective form of unemployment insurance for older workers than UI.     

Worker flows, job flows and unemployment in a matching model

Standard matching models of unemployment generate far too little volatility in unemployment and vacancies relative to the variation in the shock variables. Shimer (2005) showed that in US data the vacancy-to-unemployment ratio is about 26 times more volatile than the standard model predicts. He identified the flexibility of wages as the key issue and triggered a heated debate on possible improvements of the core model to accommodate these empirical facts. In this paper, we first document Shimer's facts for the UK and find them to be qualitatively similar to US facts. We then develop and calibrate a model based on the Mortensen and Pissarides approach that increases the volatility of the v/u ratio 20-fold compared to the standard framework. The key features of our model relate to the job creation decision by firms and the search options of workers. We allow these to search whilst employed, and firms to re-advertise jobs that have been quit from. This leads us to use a different job creation process, whereby potential vacancies, or job ‘ideas’, arise at a finite rate per period over a range of idiosyncratic productivities. Calibrating the model to UK data, we show that it delivers volatility in unemployment and vacancies much closer to, though still not as large as, that observed for the UK, whilst retaining the standard wage determination process.     

Adverse selection in credit markets and regressive profit taxation

In many countries, taxes on businesses are less progressive than labor income taxes. This paper provides a justification for this pattern based on adverse selection that entrepreneurs face in credit markets. Individuals choose between becoming entrepreneurs or workers and differ in their skill in both of these occupations. I find that endogenous cross-subsidization in the credit market equilibrium results in excessive (insufficient) entry of low-skilled (high-skilled) agents into entrepreneurship. This gives rise to a corrective role for differential taxation of entrepreneurial profits and labor income. In particular, a profit tax that is regressive relative to taxes on labor income restores the efficient occupational choice.     

Is soccer good for you? The motivational impact of big sporting events on the unemployed

We examine the effect of salient international soccer tournaments on the motivation of unemployed individuals to search for employment using the German Socio Economic Panel 1984–2010. Exploiting the random scheduling of survey interviews, we find significant effects on motivational variables such as the intention to work or the reservation wage. Furthermore, the sporting events increase perceived health as well as worries about the general economic situation.     

Life cycle employment and fertility across institutional environments

In this paper, we formulate a dynamic utility maximization model of female labor force participation and fertility choices and estimate approximate decision rules using data on married women in Italy, Spain and France. The estimated decision rules indicate that first-order state dependence is the most important factor determining female labor supply behavior in all three countries. We also find that cross-country differences in state dependence effects are consistent with the order of country-level measures of labor market flexibility and child care availability. Counterfactual simulations of the model indicate that female employment rates in Italy and Spain could reach EU target levels were French social policies to be adopted in those countries.     

Labor market reforms, job instability, and the flexibility of the employment relationship

We endogenize separation in a search model of the labor market and allow for bargaining over the continuation of employment relationships following productivity shocks to take place under asymmetric information. In such a setting separation may occur even if continuation of the employment relationship is privately efficient for workers and firms. We show that reductions in the cost of separation, owing for example to a reduction in firing taxes, lead to an increase in job instability and, when separation costs are initially high, may be welfare decreasing for workers and firms. We furthermore show that, in response to an exogenous reduction in firing taxes, workers and firms may switch from rigid to flexible employment contracts, which further amplifies the increase in job instability caused by policy reform.     

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 market rigidity and productivity growth in a model of innovation-driven growth

Empirical studies investigating the relationship between productivity performance and labor market rigidity have generated a negative result. In this paper we try to provide a theoretical explanation for this empirical result. In doing so, we construct a no-shirking model of innovation-based growth and investigate the steady-state impact of a set of active labor market policies aimed at reducing labor market rigidity and knowledge mismatch generated by innovations. We find that, while enhancing job finding activity definitively improves the equilibrium growth-unemployment mix of the economy, reducing the knowledge mismatch of innovation through active measures is less effective in reducing the equilibrium unemployment and improving growth.

Lost in transition: the costs and consequences of sectoral labour adjustment

Abstract This paper uses an equilibrium search and matching model to study Canada’s sectoral labour adjustment in 2002–2006 during an increase in global commodity prices and exchange rate appreciation. I estimate economically significant adjustment costs for the aggregate economy in this episode and demonstrate that difficulty in transferring skills between jobs for individual workers can be an important contributor to these aggregate costs. The analysis also demonstrates that the level of unemployment benefits impacts the economy’s sectoral composition, its aggregate productivity, and the speed of its adjustment to shocks.     

Do women react differently to incentives? Evidence from experimental data and payroll records

We consider the response to incentives as an explanation for observed productivity differences within a firm that paid its workers piece rates. We provide a framework within which the observed productivity differences can be decomposed into two parts: One due to differences in ability and the other due to differences in the response to incentives. We apply this decomposition to male and female workers from a tree-planting firm in British Columbia, Canada. Our evidence (both experimental and nonexperimental) suggests that there was no difference in the reaction to incentives between male and female planters. The productivity differential male planters enjoyed arose because of differences in ability, interpreted as strength in our application.     

Aid effectiveness and the soft budget constraint: EU development aid to the former Soviet Union

Aid effectiveness is defined as contractual completeness. EU development aid constitutes the new soft budget constraint in the former Soviet Union. Transnational sovereignty means that development policy is decided by the post-Soviet planner and financed by the European Commission.     

Capital markets integration, growth and income distribution

The paper considers a two-country model of overlapping generation heterogenous economies with intergenerational transfers carried out in the form of bequest and investment in human capital. We examine in competitive equilibrium the transitory and long-run effects of capital markets integration. First, we explore how the regime of public education affects the dynamics of the integrated economy. Second, we study the effects of capital markets integration, in equilibrium, on the intragenerational income distribution in both the host and investing country.     

The intergenerational transmission of maternal human capital and the gender gap in educational attainment

An intergenerational effect of maternal (and not paternal) human capital on offspring's human capital production is a mechanism that induces males and females to attain different education levels. This mechanism allows for explanations of the reversal in the gender education gap.     

Multitask principal-agent problems: Optimal contracts, fragility, and effort misallocation

We analyze a tractable class of multitask principal-agent problems, such as the one faced by a firm with a manager overseeing several projects. We allow for tasks to be complements or substitutes. We avoid the problems associated with the first-order approach by directly characterizing the shape of the agent's indirect utility function, which exhibits a convex then concave shape in effort. We identify a new source of allocational inefficiency across tasks: excessive concentration, and its consequence, insufficient risk taking. Optimal incentive schemes in our environment are generally “fragile”: small changes in fundamentals can cause the agent's effort to collapse.     

Debt, managerial compensation and learning

Using a dynamic model with uncertainty and asymmetric information, we study the impact of debt and bankruptcy on managerial compensation and learning. In this model, compensation has two roles to play—providing incentives to the manager and learning about his type. We show that debt, through bankruptcy, acts as a substitute of compensation in both dimensions and derive conditions under which debt lowers average compensation, pay-performance sensitivity and increases learning. We also examine the choice of debt and show that firm value can be increased due to debt's effect on managerial compensation, abstracting from other costs and benefits of debt. Finally, we conduct comparative statics with respect to the underlying parameters.
