Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany,Greece, Ireland,Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.     

THE IMPACT OF PERSONALITY TRAITS ON WAGE GROWTH AND THE GENDER WAGE GAP

This paper considers the impact of personality traits on the change of the gender wage gap. Using data from the German Socioeconomic Panel (SOEP), we first explore how personality traits affect wage growth rates. Then, a decomposition analysis is performed to analyse the dynamic effects of personality traits on the change of the gender wage gap over time. Our empirical results indicate that gender differences in conscientiousness and emotional stability lead to a widening of the wage gap over time. By contrast, gender differences in extraversion lead to a narrowing of the wage gap over time.     

Downward wage rigidity and job mobility

Using data from the German Socio-Economic Panel (GSOEP) we study whether being individually affected by downward wage rigidity has an effect on layoffs, quits and intra-firm mobility. Within a structural empirical model we estimate the individual extent of wage rigidity. This is expressed by the wage sweep-up, which measures by how much individual wage growth increases through the effect of downward wage rigidity when compared to a counterfactual labour market with flexible wage setting. We find robust negative effects of wage sweep-up on quits and layoffs and some evidence for a positive association of wage sweep-up and promotion opportunities. This is consistent with a core-periphery view of the labour force, where a core work force is protected from layoffs and wage cuts and at the same time enjoys good promotion opportunities. On the other side a peripheral work force provides a buffer for adjustment and suffers from both flexible wages, more insecure jobs and less internal promotion opportunities.      

How Rigid are Nominal Wages? Evidence and Implications for Germany*

Many recent attempts to find evidence on downward nominal wage rigidity in micro data have suffered from problems such as composition bias and the effects of measurement error. In this paper, a model of proportional downward nominal wage rigidity is developed which avoids these problems by taking into account the determinants of wage changes and the measurement process that leads to observable earnings changes. We find a high degree of downward nominal wage rigidity in German micro data. Its real implications for individual expected wage growth, the aggregate wage level and equilibrium unemployment have marked effects for rates of inflation lower than 3 percent.     

Economic growth, skill-biased technical change and wage inequality: A model and estimations for the US and Europe

In recent literature skill-biased technical change has been viewed as a major cause for wage inequality. Some modelling and presentation of stylized facts have been undertaken for US time series data. A preliminary study of wage inequality in a model with knowledge as input in an aggregate production function has been presented by Riddell and Romer [General Purpose Technologies and Economic Growth, 1998, MIT Press]. Although some important forces determining wage inequality are widely accepted we know little about the quantitative impact of each source and differences across countries. We present a growth model of the Romer type with innovation-based technical change and two skill groups where the growth of knowledge, the relative supply of the two skill groups, externalities and substitution effects among the two groups are the driving forces for wage inequality. We undertake estimates for US time series data and contrast those estimates with results from some European countries. In particular, we compare parameter estimations for US and German time series data. The paper concludes that there is less wage inequality across skills in Europe in contrast to the US on the macroeconomic level. But, considering disaggregated data we observe some increases in inequality for Germany, too. Although our model reveals important variables for the explanation of wage inequality there may, however, also be other factors, such as trade unions, which have impacted the wage spread.     

The incidence of,and returns to overeducation in the UK

Drawing on German data we look for evidence of a supply-side political business cycle. The hypothesis suggests that centralized trade unions with political interests and some degree of monopoly power may fine-tune their collective wage bargaining strategies so as to help preferred or to harm rejected parties in power. The regression results confirm that between 1960 and 1988 German trade unions exercised additional wage pressure before general elections under a Christian Democratic incumbent drew closer, trade unions pursued a restrictive wage policy to promote the government' chances for re-election.     

Wages in the East German Transition Process: Facts and Explanations

We analyze wage developments in the East German transition process both at the macro- and at the microeconomic level. At the macroeconomic level, we draw special attention to the important distinction between product and consumption wages, describe the development of various wage measures, labor productivity and unit labor costs in East Germany in relation to West Germany, and relate these developments to the system of collective wage bargaining. At the microeconomic level, we describe changes in the distribution of hourly wages between 1990 and 1997 and analyze the economic factors determining these changes by way of empirical wage functions estimated on the basis of the Socio-Economic Panel for East Germany. The paper also draws some conclusions on the likely future course of the East–West German wage convergence process.     

‘HAVE YOU FELT ANGRY LATELY?’: A NOTE ON UNFAIR WAGE PERCEPTIONS AND THE NEGATIVE EMOTION OF ANGER

The author analyses the nexus between unfair wage perceptions of workers and the frequency of the negative emotion of anger. For this purpose, German household panel data for the years 2007, 2009, 2011 and 2013 are used. Angry feelings in the last four weeks have occurred significantly more frequently for workers who perceive their wage as unfair, whereas the own absolute hourly wage is not significantly correlated with the frequency of having felt angry. The results further indicate that workers have felt more often angry if working hours are larger; but the economic significance seems rather small compared to unfair wage perceptions.     

Social comparisons of wage increases and job satisfaction

We combine status quo and social comparison considerations and investigate whether relative wage increases in the sense of differences between individual wage increases and wage increases of comparable employees are related to managers’ job satisfaction. Using a panel data set of managers in the German chemical industry, we indeed find first evidence. The relation between relative wage increases and job satisfaction is relevant for managers with lower absolute wage levels in particular.     

The Extent and Impact of Enterprise Training: The Case of Kitakyushu City

This paper examines the incidence and intensity of training as well as the impact of training on wage growth, using a unique survey of establishments and employees in Japan. We find that the worker's probability of receiving certain forms of training depends not only on union status, occupation, education, age and past job experience, but also on the business types and practices of the firms. Our evidence also suggests that formal training is associated with the measures of business growth. Controlling for such growth measures, both the incidence of routine formal training and the duration of informal training are found to boost wage increases.

The German generation internship and the minimum wage introduction: evidence from big data

The new German minimum wage applies a specific exemption clause for internships, where internships that last up to three months are exempted while internships that exceed three months are due to the minimum wage. Negative minimum wage effects on internships are heavily debated as internships are mostly non-productive. Difference-in-difference analyses that exploit establishment and regional variation in the bite of the minimum wage do not show a reduction in the number of internships. In addition, we pursue an innovative approach by using Google search data to analyse how the search intensity for internships changed in course of the minimum wage introduction. Difference-in-difference comparisons with other countries in Europe do not reveal an effect on the search for internship positions in general, but we observe a significant reduction in Google search for ‘generation internship’. This suggests that the underlying societal phenomenon of a generation entering internships without a perspective for regular jobs has lost in relevance.     

Unification and the policy predicament in Germany

We argue that wages have increased so far ahead of labour productivity in east Germany as to produce a problem that will continue to hound German policy-makers for the next two decades. Despite rapid rates of capital accumulation (around 9%) and growth (around 5%) in east Germany over the coming 10 years, our estimates show that even if wage catch-up decelerates greatly, as long as it continues, the rate of unemployment in the east will still be twice as high as in the west in another 10 years. Alternatively, if wage discipline forces the eastern unemployment rate to come down to the western level, wage differentials will widen substantially over these next 10 years. Thus serious problems loom ahead.     

Educational mismatch and promotions to managerial positions: a test of the career mobility theory

Career mobility theory suggests that given a certain occupation, schooling improves upward mobility in terms of promotion and wage growth. We are the first to test the implications of this theory for over- and undereducation by means of direct information about promotions to managerial positions. Using German administrative data entailing an employer-reported – and hence objective – measure of educational requirements, we show that overeducated workers are indeed more likely to be promoted and that this career mobility advantage is more pronounced in the early stages of their working lives. By contrast, undereducated workers are less likely to be promoted to managerial positions. Moreover, in terms of wage growth, while overeducated workers benefit more, undereducated workers benefit less from promotions than their well-matched educational peers. Altogether, these findings strongly support the career mobility theory. Furthermore, by differentiating between internal and external promotions, we provide evidence that promotions are more likely for overeducated workers within the establishment, whereas the opposite applies for undereducated workers. This finding indicates the relevance of both over- and undereducation as signals of true ability to other employers.     

Schooling, Training, Growth and Minimum Wages

We examine how the long-run growth performance of an economy is affected by a labor market distortion. In our model, growth occurs through skill formation, and skills are generated through schooling and training of unskilled workers. We analyze how a minimum wage legislation affects long-run growth. In general, the effects are ambiguous. The reason is that while a minimum wage discourages training, it also encourages schooling. The net effect then depends on whether training or schooling dominates the long-run increases in labor productivity.

The composition of wage differentials between migrants and natives

We consider the role of unobservables, such as differences in search frictions, reservation wages, and productivities for the explanation of wage differentials between migrants and natives. We disentangle these by estimating an empirical general equilibrium search model with on-the-job search due to Bontemps et al. (1999) on segments of the labour market defined by occupation, age, and nationality using a large scale German administrative dataset.The native-migrant wage differential is then decomposed into several parts, and we focus especially on the component that we label “migrant effect”, being the difference in wage offers between natives and migrants in the same occupation-age segment in firms of the same productivity. Counterfactual decompositions of wage differentials allow us to identify and quantify their drivers, thus explaining within a common framework what is often labelled the unexplained wage gap.     

Multiple Wage Bargaining Systems in the Single European Currency Area

Little attention in the EMU literature has been paid to the interaction between centralbank monetary rules and systems of collective wage bargaining. Analytically andempirically, coordinated wage bargaining systems respond with real wage restraintto non-accommodating monetary policy. Since wage determination is dominated bycollective bargaining in all the EMU member states and wage coordination within themember states has grown since 1980, this is a topic of potential importance. In particular, the replacement of the Bundesbank, directly targeting German inflation, by an ECB targeting European inflation has removed a major institutional support of wage restraint in Germany. The consequences of this for EMU are worked out under two scenarios, that inflation expectations will be generated by ECB monetary policy and that they will reflect German inflation outcomes. Possible institutional developments are discussed including government-union bargains. The Bundesbank has also played a major role in maintaining fiscal rectitude by targeting excess fiscal deficits in Germany: again its replacement by the ECB – targeting (if at all) European rather than German fiscal policy – loosens fiscal constraints. For underlying structural reasons therefore, it is possible that Germany and other EMU countries will move to a period of fiscal activism with wage restraint and low inflation purchased through social contract negotiations.     

The wage effects of training in Portugal: differences across skill groups,genders, sectors and training types

This article investigates the determinants and wage effects of training in Portugal. In a first stage, we show that there are considerable differences in training participation across groups of workers, with elder and low educated individuals participating substantially less. In a second stage, we show that training has a positive and significant impact on wages. The estimated wage return is about 30% for men and 38% for women. Discriminating between levels of education and working experience and the public and private sector reveals important differences across categories of workers. We find that women, low educated workers and workers with long working experience earn larger returns from training. The average effect of training is similar in the private sector and the public sector. However, differences across experience groups are larger in the private sector, while differences across education groups are larger in the public sector. We use three alternative classifications of training activities and find that training in the firm, training aimed to improve skills needed at the current job and training with duration less than a year are associated to larger wage gains.     

Do earnings subsidies affect job choice? The impact of SSP subsidies on job turnover and wage growth

Abstract .  This paper explores the impact of earnings subsidies on job duration and wage growth. We develop an analytical framework that predicts that convex subsidies increase job turnover and affect within-job and between-job wage growth. This framework is used to analyze the effects of the Canadian Self-sufficiency Project earnings subsidy. We find that the treatment group had shorter job duration and experienced faster wage growth than controls, which is consistent with the analytical model. Results for between-job wage growth hold after we correct for compositional bias, but we cannot rule out that within-job wage growth was not affected by the program.     

Creating low skilled jobs by subsidizing market-contracted household work

The paper analyses the determinants of household work contracted in the German shadow economy. The German socio-economic household panel, which enumerates casual domestic employment, is used to estimate the demand for such household work. The regressors include regional wage rates, household income and several control variables for household composition. It is found that the demand for household work in the shadow economy is very income elastic. This suggests that targeted wage subsidies, linked to household work agencies, would be very effective in raising the legal demand for domestic help. A wage subsidy of 50% of wage costs could thus establish up to 500?000 new jobs for previously unemployed or non-working low skilled workers. The net fiscal costs of such a scheme are about 6.200 Euro per full-time job. In addition, society benefits from more law enforcement and from a raised female labour supply, especially by highly qualified mothers.     

International Trade and Collective Bargaining Outcomes: Evidence from German Employer–Employee Data

In theoretical trade models with variable mark‐ups and collective wage bargaining, exposure to international markets might reduce the exporter wage premium. We test this prediction using linked German employer–employee data covering the years 1996–2007. To separate the rent‐sharing mechanism from assortative matching, we exploit individual worker information to construct profitability measures that are free of skill composition. Our results show that rent‐sharing is less pronounced in more export‐intensive firms or in more open industries. The exporter wage premium is highest for low‐productivity firms. In line with theory, these findings are unique to the subsample of plants covered by collective bargaining.
