Better Safe than Sorry? The Effects of Income Risk and Unemployment Risk on Wages

We study the effects of income risk and unemployment risk on individual wages simultaneously. Starting point for the empirical analysis is a portfolio model for the labor market. This model shows positive wage effects for both risks but also a negative interaction effect. Using German administrative panel data we estimate the effects of the income risk, the unemployment risk and their interaction on individual wages separately for men and women in East and West Germany. We find the expected positive wage effects for both risks as well as a negative interaction effect. The marginal effect of income risk on wages is positive, whereas the marginal effect of unemployment risk is negative.     

STAUNCHING EMIGRATION FROM EAST GERMANY: AGE AND THE DETERMINANTS OF MIGRATION

Following the unification of Germany in 1990, eastern wages and unemployment both rose rapidly. I demonstrate that rising wages reduced eastern emigration greatly, while rising unemployment had little effect. This reflects the behavior of the young, who are very sensitive to source region wages, and relatively insensitive to source unemployment. I show that most of the effect of source unemployment comes from the contemporaneous effect on those laid‐off, who are more likely to be older. I find that, compared to stayers, young emigrants are much more skilled, older emigrants are slightly more skilled, and commuters are not more skilled, as measured by education and pre‐move wages. My conclusions are based on a comparison of results from aggregate inter‐state migration data and individual data from the eastern sample of the German Socio‐Economic Panel for 1990–2000.

Crime and Labour Market Opportunities in Italy (1993–2002)

Abstract. This paper investigates the relationship between labour market conditions and crime in Italy accounting for both age and gender in the unemployment measure and considering regional disparities between the North‐Centre and the South of Italy. Using regional data over the period 1993–2002, we study the impact of wages and unemployment on different types of crime. To mitigate omitted variables bias, we control extensively for demographic and socio‐economic variables. Empirical results suggest that unemployment has a large and positive effect on crime rates in southern regions. Our results are robust to model specification, endogeneity, changes in the classification of crimes, and finally, to alternative definitions of unemployment.     

MEASURING LABOR MARKET FRICTIONS: A CROSS‐COUNTRY COMPARISON

In this paper we define and estimate measures of labor market frictions using data on job durations. We compare different estimation methods and different types of data. We propose and apply an unconditional inference method that can be applied to aggregate duration data. It does not require wage data, it is invariant to the way in which wages are determined, and it allows workers to care about other job characteristics. The empirical analysis focuses on France, but we perform separate analyses for the United States of America, the United Kingdom, Germany, and the Netherlands. We quantify the monopsony power due to search frictions and we examine the policy effects of the minimum wage, unemployment benefits, and search frictions. (JEL: J63, J64)     

Wage Flexibility for Skilled and Unskilled Workers: New Evidence on the Norwegian Wage Curve

Empirical evidence is provided in favour of a hypothesis that wages for unskilled workers are more responsive to unemployment than wages for skilled workers. The results imply vigorous wage responsiveness to low levels of unemployment for both groups, while the wage curves become almost entirely flat for unemployment rates above 1.7 percent. One interpretation of this result is that firms have strong incentives to increase wages in order to recruit and retain workers when unemployment is below some critical level. Since unemployed workers will certainly find work, the expected costs of a job loss are small, as are costs associated with an egalitarian wage policy.     

Noncontractible Heterogeneity in Directed Search

This paper provides a directed search model designed to explain the residual part of wage variation left over after the impact of education and other observable worker characteristics have been removed. Workers have private information about their characteristics at the time they apply for jobs. Firms value these characteristics differently and can observe them once workers apply. They hire the worker they most prefer. However, the characteristics are not contractible, so firms cannot condition their wages on them. This paper shows how to extend arguments from directed search to handle this, allowing for arbitrary distributions of worker and firm types. The model is used to provide a functional relationship that ties together the wage distribution and the wage–duration function. This relationship provides a testable implication of the model. This relationship suggests a common property of wage distributions that guarantees that workers who leave unemployment at the highest wages also have the shortest unemployment duration. This is in strict contrast to the usual (and somewhat implausible) directed search story in which high wages are always accompanied by higher probability of unemployment.     

A Note on Job Tenure and Collective Contracts

Abstract. This paper analyses the relationship between individual tenure and the application of collective contracts at the firm level under the specific institutional settings in Germany. The empirical approach is based on a multilevel model and a linked employer–employee data set for the years 1990, 1995, and 2001. The main result is that elapsed tenure is longer in firms applying collective contracts than in companies with individual wage setting: workers in firms with collective contracts benefit not only from higher wages, but also from higher job stability. Furthermore, we find no significant changes in mean tenure during the 1990s as well as stable differences across wage‐setting regimes.     

Descrepancies between Supply and Demand and Adjustment Processes in the Labour Market

Changes in demand and supply in segments of the labour market will affect the labour market position of workers with an educational background in a related field of study. In one economic tradition such discrepancies between supply and demand are thought to lead to unemployment in the case of excess supply and to unfilled vacancies or skill shortages in the case of excess demand. The other neo‐classical oriented tradition expects wage adjustments to take fully account of these labour market imbalances, leading to higher wages for studies with excess demand and lower wages in case of excess supply. In practice the labour market might, on the one hand, be more flexible than suggested by the first approach, but on the other hand adjustment might be incomplete and not only wages but also other aspects of the employment relationship might be affected by a friction between supply and demand. This study examines the relationship between discrepancies between labour demand and supply on the one hand and manifestations of these tensions in the labour market experience of school‐leavers on the other hand. To investigate this relationship, a random coefficient model has been used, which allows for different adjustment processes for the various educational types, but still makes full use of all the information available in the data. The analyses provide insights about the importance of different adjustment processes and their complementarity and substitutability. We show that on average, supply surpluses lead to pressure to accept jobs at a level which is lower than the school‐leavers educational level, jobs with relatively low wages, and jobs with part‐time contracts. A direct link between supply surpluses and unemployment is only found for a few specific fields of study. Unemployment seems to occur mostly when school‐leavers do not take temporary jobs or jobs below their educational level in case of excess supply.     

Union Density and Relative Wages: What is the Relationship?

ABSTRACT: This paper examines the impact of union density on relative wages under decentralised bargaining settings. Whilst, traditionally, empirical studies have focused on the impact of union status on wages (either at the individual or at the plant level), here it is argued that local trade union density can have an independent (positive) effect on wages. This occurs through the threat of collective action and the ability of the union to impose costs onto employers. First, a Nash bargaining model is presented under efficient-bargaining settings, and a wage-membership equation is derived. Wages are shown to be an increasing and convex function of union membership. Second, an empirical specification of the wage-membership equation, suitable for estimation, is obtained and fitted to establishment-level data for the Italian metal-mechanical engineering industry. A positive monotonic relationship between wages and union density is detected. Furthermore, wages are shown to be increasing with union density even where no formal local bargaining agreement is in force, thus suggesting that “union-threat” effects might be relevant.

Wage Bargaining and Profitability: A Disaggregative Analysis

Abstract. Previous analyses of the wage/profit relationship at a disaggregative level in Britain have given positive results for pre-war years but negative results for early post-war years. However, this is probably due to the increasingly unreliable nature of the enterprise- based profits series published in the National Accounts until 1982. We have constructed, instead, what are essentially establishment-based Census data on profits for fourteen manufacturing industries, up to 1986. We have also been able to extend the disaggregative unemployment data, the publication of which also ceased in 1982. The wage equations that we have estimated include profits and unemployment (and other variables) in an explicit Nash bargaining model, in line with widely held views as to the way that wage negotiations are actually conducted. The results obtained show a highly significant role for profits, as well as having other implications, notably the positive (hysteresis) effect of industry unemployment, by contrast with the normal negative effect of aggregate unemployment, and the important effects of relative wages - which play a large role in various disaggregative studies of the propagation of inflation.     

Minimum Wage Effects on Labor Market Outcomes under Search,Matching, and Endogenous Contact Rates

Building upon a continuous‐time model of search with Nash bargaining in a stationary environment, we analyze the effect of changes in minimum wages on labor market outcomes and welfare. Although minimum wage increases may or may not lead to increases in unemployment in our model, they can be welfare‐improving to labor market participants on both the supply and demand sides of the labor market. We discuss identification of the model using Current Population Survey data on accepted wages and unemployment durations, and show that by incorporating a limited amount of information from the demand side of the market it is possible to obtain credible and precise estimates of all primitive parameters. We show that the optimal minimum wage in 1996 depends critically on whether or not contact rates can be considered to be exogenous and we note that the limited variation in minimum wages makes testing this assumption problematic.     

Einfluss von Vorgesetzten, T?tigkeit, Arbeitsbedingungen und variabler Besoldung auf die Motivation von Mitarbeitern im ?ffentlichen Dienst

This paper analyses the effects of four main influence factors on motivation of public personnel. These influence factors are “superior”, “job satisfaction”, “work environment”, and “variable wages”. I analyse the four factors by using a structural equation model with empirical data. My focus lies on the complex interdependencies of influence factors among each other. There is empirical evidence that the influence factor “job satisfaction” plays a decisive role in public service motivation. Moreover, the influence factors “work environment” and “variable wage” have a quite low direct effect on motivation. Surprisingly, the influence factor “superior” has an strong effect on “job satisfaction” and on “variable wages”.     

Labour Market Regulation,Flexibility and Employment

ABSTRACT: Chronic unemployment and slow employment growth in some countries have led to calls for more labor-market “flexibility”. This paper defines the flexibility issue in terms of legally-mandated “severance”, a generalized employment cost linked to seniority. A mandated severance benefit can stand for a variety of programs including employer-provided employment guarantees, payments which must be made to laid-off workers, and compensation for wrongful discharge. Such a mandated cost can be seen as a payroll tax on the employer, raising the issue of tax incidence. Employers often take the view that labor costs are given and that mandated costs are simply add-ons to pre-existing cost levels. However, the literature on tax incidence suggests that a significant portion of “employer-paid” payroll taxes are shifted to labor in the form of lower wages. Such shifting should reduce the dis-employment effects attributed to severance. A model is provided of a firm upon which a severance mandate is imposed. Even at the micro level, the firm can shift some of the cost of severance to employees by lowering wages — although at the expense of higher turnover costs associated with increased quit rates. At the macro level, to the extent that firms reduce employment, there could be still further downward wage adjustments which would shift the severance burden to labor and mitigate the dis-employment effect. Ultimately, if the natural rate of unemployment is raised by severance mandates, the age-old question is raised of why wages do not fall in the face of labor surpluses. The true inflexibility to be explained, therefore, is in wage determination.     

Wage Dispersion and Equilibrium Search Models: Some Evidence from Italy

This paper provides a structural estimation of an equilibrium search model with on‐the‐job search and heterogeneity in firms' productivities using a sample of Italian male workers. Results indicate that arrival rates of offers for workers are higher when unemployed than when employed and firms exploit their monopsony power when setting wages. As a result, workers earn far less than their marginal product. The model is then used to study regional labour market differentials in Italy. Wide variation in frictional transition parameters across areas helps to explain persistent unemployment and wage differentials.     

A Dynamic Model for the Cross‐sectional Distribution of Unemployment Rates

This paper proposes a model to describe the continuous time‐evolution of density of the cross‐sectional distribution of unemployment rates. The model is founded on the theory of analytical diffusion processes. The steady‐state distribution as well as the dynamic behaviour of the model are analytically derived. Parameters in the resulting analytical expressions are then fitted to US regional data. The empirical portion of the paper illustrates the usefulness of modeling the temporal evolution of the cross‐sectional distribution of unemployment rate, rather than simply attending to equilibrium implications of the process.     

Union Bargaining,Wage Differentials and Employment

Abstract. Reviewing empirical studies concerning the corporatism-flexibility-performance nexus the paper discusses decentralized and centralized bargaining systems. Revenue pay systems, concession bargaining and two-tier wage systems as means to enhance wage flexibility at the firm level are also considered. Both theoretical and empirical evidence is presented, showing that unions are bargaining for greater employment security for the already employed (the insiders). In return, unions are ready to accept greater wage flexibility and even wage decreases. By contrast, the insider-outsider theory does suggest how unions may accentuate involuntary unemployment, because there may be ways in which a union can help to raise the wages of the insiders without reducing their chances of continued employment.     

Price Effects of the Minimum Wage: A Survey Data Analysis for the German Construction Sector

Utilizing the link between employment and price changes as a result of minimum wages, we use firm‐level data to evaluate the effect of minimum wage introduction in the German construction sector. In East Germany we find significant positive price effects that exclude the possibility of rising employment. Rather, the results indicate the existence of a competitive sector‐specific labour market, and thus declining employment. In contrast, we cannot find any significant price reaction for West Germany. This suggests that the implemented minimum wage in West Germany is too low in comparison to the predominantly paid wages and is hence not binding.     

The Unemployment Volatility Puzzle: Is Wage Stickiness the Answer?

I discuss the failure of the canonical search and matching model to match the cyclical volatility in the job finding rate. I show that job creation in the model is influenced by wages in new matches. I summarize microeconometric evidence and find that wages in new matches are volatile and consistent with the model's key predictions. Therefore, explanations of the unemployment volatility puzzle have to preserve the cyclical volatility of wages. I discuss a modification of the model, based on fixed matching costs, that can increase cyclical unemployment volatility and is consistent with wage flexibility in new matches.     

Effects of Regional Labour Markets on Migration Flows,by Education Level

European economies display large variations in unemployment rates across regions as well as between education groups. Insufficient labour mobility is widely believed to contribute to higher regional disparities and overall unemployment, but few studies have compared mobility responses of different education groups to regional shocks. This paper employs administrative registers covering the entire Norwegian population to compute annual time series from 1994 to 2004 of migration flows and regional labour market conditions by education level for 90 travel‐to‐work areas. We find that regional disparities in unemployment rates are decreasing in education level, whereas the response of migration flows to regional unemployment shocks is increasing in education level. The results suggest that low regional mobility of low‐educated workers may contribute to higher regional disparities and higher overall unemployment among the low educated.
