The Union Effect on Wages in Chile: A Two‐Stage Approach Using Panel Data

We estimate the union effect on wages in Chile to be between 18 and 24 per cent. We follow a two‐stage procedure that allows us to correct the endogeneity of union status and to separate true from spurious dependence, by exploiting the union history of individuals using panel data. We find evidence of comparative‐advantage sorting in union status, strong true state dependence and a re‐distributional effect of union membership (i.e. wage gains from unionization are larger for lower‐wage earners).     

Risk Aversion,Collective Bargaining,and Wages in Germany

We develop an open‐shop model of trade union membership in which workers differ in their risk attitudes, and derive conditions under which the bargained wage will fall and union membership will increase with a general rise in risk aversion. Using data from the German Socio‐Economic Panel we define broad bargaining units and show that wages decline as average risk aversion of union members in these units rises, controlling for individual effects of risk aversion. Given a negative relationship between wages and employment, this suggests that secular changes in risk attitudes, because of an aging workforce or greater female labour force participation, can help to explain variations in the employment performance of unionized economies.     

Changes in Union Membership Over Time: A Panel Analysis for West Germany

Abstract. Despite the apparent stability of the wage bargaining institutions in West Germany, aggregate union membership has been declining dramatically since the early 1990s. However, aggregate gross membership numbers do not distinguish between employment status and it is impossible to disaggregate these sufficiently. This paper uses four waves of the German Socio‐economic Panel in 1985, 1989, 1993, and 1998 to perform a panel analysis of net union membership among employees. We estimate a correlated random‐effects probit model suggested by Chamberlain (Handbook of Econometrics, Vol. II, Amsterdam: Elsevier Science, 1984) to take proper account of individual‐specific effects. Our results suggest that at the individual level the propensity to be a union member has not changed considerably over time. Thus, the aggregate decline in membership is due to composition effects. We also use the estimates to predict net union density at the industry level based on the IAB employment subsample for the time period 1985–97.     

A Causality Analysis of Economic Growth and Union Density in European Countries

In this paper, we analyse the relationship between union density and economic growth using a Granger causality analysis and shocks analysis with vector autoregression model. We find that the Granger causality goes from the growth rate to the unionization rate in four of the 11 European countries under study. France bucks the trend: it is the only country in which union density influences economic growth, moreover in a positive way.     

The Rise in Union Wage Premiums in South Africa

The earnings premium received by African, urban, male union members in South Africa, as compared to other regular, urban male employees, is explored using two national sample surveys conducted in 1985 and 1993. The historical setting of this change is of particular interest, in the light of the transformation from the apartheid regime. Union membership grew very rapidly during this interval, as earlier prohibitions on African unions were lifted. Subsequently, the high rates of unemployment and segmentation of the labor force have been issues of central concern to the new government, elected in 1994. In this context, the paper extends prior methodology, by systematically comparing possible approaches to estimation, in addition to contributing fresh empirical results. Four approaches to estimation are adopted, allowing for: a single earnings regime with union dummy variable; the possibility of different earnings regimes among union members as compared to non‐members; endogenous switching between such regimes; sample selection arising from lack of employment and from division between regular and informal work. A series of tests on nested specifications indicate the importance of recognizing endogenous switching between differing pay structures in the covered and uncovered sectors. However (as with previous research on the South African labor market), no sample selection is detected with respect to employment status. The results suggest that collective bargaining resulted in wage compression among the expanding union membership while significantly widening the gap between members and non‐members. The latter widening gap cannot be attributed to the changing composition of union membership as reflected in observed characteristics of employees.     

Union Membership and the Union Wage Gap in the UK

We consider the choice of union membership in the UK and its effect on the union/non‐union wage differential allowing for the endogeneity of the union choice. We include identifying variables not previously used and find that correcting for selectivity is important and has a large impact on the estimated differential. Moreover, union choice is itself affected by the wage gap.     

SKILL‐BIASED TECHNOLOGICAL CHANGE,UNEMPLOYMENT, AND BRAIN DRAIN

We develop a model of directed technology adoption, frictional unemployment, and migration to examine the effects of a change in skill endowments on the wages, employment rates, and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution between skilled and unskilled workers and the elasticity of the matching function, an increase in the skill ratio can reduce both the relative unemployment rate and the relative emigration rate (brain drain) of skilled workers. We provide numerical simulations to support our findings and show that the effects are empirically relevant and potentially sizable.     

Trade Union Membership and the Free Rider Problem: the Role of Harassment Activities

Abstract. Although there exists an extensive literature which uses econometric techniques to examine the process of unionisation in the industrial countries, a well established theory about the individual propensity to join the union has still to be developed. We feel that the workers' personal relationships in the working places impinge on their decision to unionise. To this end, we have set out a coercion model of trade union membership without compulsory membership, based on the rank and file union members' harassment activities. Union members use these unfriendly activities to eliminate the free-rider ploblem, encouraging unionisation and reducing the cost of joining a union.     

‘Investment’ in Union Membership: A Managerial Approach

This paper concerns wage formation in a unionized economy when union membership is endogenous and determined by employment. A union is run by a leadership which has as an objective to strengthen the union’s position in the labour market. This is achieved by building up membership. Among the results, it is found that since membership is determined by employment, the inclusion of the leadership’s preferences into a union’s objective function produces lower real wages than a static version would predict. It is also shown that an increase in the union’s rate of time preference increases the natural rate of unemployment, while an increase in the speed at which workers enter/leave a union has an opposite effect.     

DO IMMIGRANTS CAUSE CRIME?

We examine the empirical relationship between immigration and crime across Italian provinces during the period 1990–2003. Drawing on police administrative records, we first document that the size of the immigrant population is positively correlated with the incidence of property crimes and with the overall crime rate. Then, we use instrumental variables based on immigration toward destination countries other than Italy to identify the causal impact of exogenous changes in Italy’s immigrant population. According to these estimates, immigration increases only the incidence of robberies, while leaving unaffected all other types of crime. Since robberies represent a very minor fraction of all criminal offenses, the effect on the overall crime rate is not significantly different from zero.     

The Role of Profit Sharing in Dual Labour Markets with Flexible Outsourcing

We combine profit sharing for high‐skilled workers and outsourcing of low‐skilled tasks in a partly imperfect dual domestic labour market, which means that only low‐skilled labour is represented by a labour union. In that framework we analyse how the implementation of profit sharing for high‐skilled workers influences the amount of outsourcing and the labour market outcome for low‐skilled worker. By doing this, we use some specific assumptions, e.g. exponentially increasing outsourcing costs or the wage for low‐skilled workers will be determined by a union whereas the wage for high‐skilled workers is given. Assuming that low‐skilled labour and outsourcing are interchangeable we show that profit sharing has a positive effect on the wage for low‐skilled workers and helps to decrease wage dispersion. However, under these circumstances, profit sharing enhances outsourcing. Concerning the employment effects for high‐ and low‐skilled workers, we show that there is an employment reducing effect due to higher wages for low‐skilled work, which can be offset by higher productivity of highly skilled workers, as the domestic labour inputs complement each other.     

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.     

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.     

Jurassic Union Man? A Profile of the British Trade Union Member

This paper examines the determinants of trade union membership in Great Britain utilising micro-data taken from the British Social Attitudes Survey over the period 1985–91. Our results suggest that, contrary to previous micro-studies, personal characteristics and the perceptions of workers' attitudes as regards their working environment impact significantly upon the decision to join a trade union. Moreover, it would appear that the union membership decision is becoming increasingly endogenised, especially in the case of the white-collar worker.     

HOW DESTRUCTIVE IS CREATIVE DESTRUCTION? EFFECTS OF JOB LOSS ON JOB MOBILITY,WITHDRAWAL AND INCOME

We analyze short and long‐term effects of worker displacement. Our sample consists of male workers displaced from Norwegian manufacturing plants. We find that displacement increases the probability of leaving the labor force by 31%. The drop‐out rate from the labor force is particularly high in the first years following displacement. The average earnings effects for those who remain in the labor force are moderate, a 3% loss relative to non‐displaced workers after seven years. Splitting displaced workers on within‐ and between‐firm movers, we find that the estimated earnings loss is entirely driven by between‐firm movers who experience a 3.6% loss. Transfers to other plants within multi‐plant firms upon displacement are quite common. Our results support the view that human capital is partly firm specific and partly industry specific. We find no evidence suggesting that human capital is plant specific.     

CIVIL SOCIETY AND THE STATE: THE INTERPLAY BETWEEN COOPERATION AND MINIMUM WAGE REGULATION

In a cross‐section of countries, state regulation of labor markets is negatively correlated with the quality of labor relations. In this paper, we argue that these facts reflect different ways of regulating labor markets, either through the state or through the civil society, depending on the degree of cooperation in the economy. We rationalize these facts with a model of learning of the quality of labor relations. Distrustful labor relations lead to low unionization and high demand for direct state regulation of wages. In turn, state regulation crowds out the possibility for workers to experiment negotiation and learn about the potential cooperative nature of labor relations. This crowding out effect can give rise to multiple equilibria: a “good” equilibrium characterized by cooperative labor relations and high union density, leading to low state regulation; and a “bad” equilibrium, characterized by distrustful labor relations, low union density, and strong state regulation of the minimum wage.     

Does Rent‐sharing Profit Female and Male Workers? Evidence from Israeli Matched Employer–Employee Data

This paper analyses the impact of workplace characteristics on individual wages based on a unique cross‐section matched employer–employee data set for the Israeli private manufacturing sector in 1995. Specifically, we examine the effects of the interaction between profit‐sharing and wages on the gender wage gap. The empirical findings show that individual compensation is significantly and positively correlated with firms’ profits‐per‐employee, even when controlling for all of the following: group effects in the residuals, individual and firms’ characteristics, industry wage differentials and endogeneity of profits. Wage–profit elasticity is found to be 11 per cent and it does not significantly differ between genders. With respect to the overall gender wage gap (on average women earn 28 per cent less than men), the results show that within firms there is no gender discrimination and that 12 per cent of this gap can be explained by the wage–profits profile and by the fact that women are more likely to be employed in less profitable firms than men.     

Join the Union and Be Safe: The Effects of Unionization on Occupational Safety and Health in the European Union

This paper investigates the effect of unionization on occupational safety and health, as measured by the fatal and non‐fatal work accidents, after controlling for the country's gross domestic product. It uses a panel sample of 10 European Union countries, for the period 1982–2006. The study takes into account the time persistence in work injuries and the endogenous nature of the work injuries–union density relationship. In addition, the effect of union density is decomposed into a temporary and permanent effect. It is shown that increasing union density is associated with a decrease in the number of both fatal and non‐fatal work injuries.     

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.     

RETHINKING THE EFFECT OF IMMIGRATION ON WAGES

This paper calculates the effects of immigration on the wages of native US workers of various skill levels in two steps. In the first step we use labor demand functions to estimate the elasticity of substitution across different groups of workers. Second, we use the underlying production structure and the estimated elasticities to calculate the total wage effects of immigration in the long run. We emphasize that a production function framework is needed to combine own‐group effects with cross‐group effects in order to obtain the total wage effects for each native group. In order to obtain a parsimonious representation of elasticities that can be estimated with available data, we adopt alternative nested‐CES models and let the data select the preferred specification. New to this paper is the estimate of the substitutability between natives and immigrants of similar education and experience levels. In the data‐preferred model, there is a small but significant degree of imperfect substitutability between natives and immigrants which, when combined with the other estimated elasticities, implies that in the period from 1990 to 2006 immigration had a small effect on the wages of native workers with no high school degree (between 0.6% and +1.7%). It also had a small positive effect on average native wages (+0.6%) and a substantial negative effect (−6.7%) on wages of previous immigrants in the long run.
