Job mobility and careers in firms

This paper presents a theoretical model that combines employers learning about worker productivity, human capital acquisition, job-assignment and resolution of worker uncertainty regarding disutility of work from a job, to show how widely documented findings on both wage and promotion dynamics and turnover can be captured in a single set-up. Specifically we show how our model can capture results such as; probability of turnover decreases with labor market experience, wage changes during job changes is more in earlier periods, serial correlation in wages and probability of promotion increases in wages, amongst others.     

Empirical evidence on occupation and industry specific human capital

This paper presents instrumental variables estimates of the effects of firm tenure, occupation specific work experience, industry specific work experience, and general work experience on wages using data from the 1979 Cohort of the National Longitudinal Survey of Youth. The estimates indicate that both occupation and industry specific human capital are key determinants of wages, and the importance of various types of human capital varies widely across one-digit occupations. Human capital is primarily occupation specific in occupations such as craftsmen, where workers realize a 14% increase in wages after five years of occupation specific experience but do not realize wage gains from industry specific experience. In contrast, human capital is primarily industry specific in other occupations such as managerial employment where workers realize a 23% wage increase after five years of industry specific work experience. In other occupations, such as professional employment, both occupation and industry specific human capital are key determinants of wages.     

Wage changes through job mobility in Europe: A multinomial endogenous switching approach

This paper presents evidence on the relationship between job mobility and wage mobility for various European countries using the European Community Household Panel (1994–2001). While much of the earlier research uses least-squares regression to predict wages for individuals with different labour market experience, we have found that it is important to take into account the possible non-random selection between job movers and stayers and between voluntary and involuntary movers. In this paper we focus on the effects of an unemployment spell on subsequent wages by estimating a multinomial endogenous switching model composed of two selection equations and three wage equations. Our results indicate that job mobility through unemployment has negative returns in all the analysed economies. As regards stayers, these losses range from 8% in Portugal to 21% in Germany while losses with respect to voluntary movers vary from 14% in Spain to 31% in Portugal.     

Seniority,experience, and wages in the UK

This paper uses BHPS data to investigate the relative importance of seniority and experience in determining male wages in the UK labor market. Using both the Altonji and Shakotko instrumental variable and the Topel two-step estimation approaches, I find that for all male workers, tenure plays a modest role, increasing wages by about 1% each year over the first 10 years on the job. General labor market experience has a larger role, so that after 30 years wages have increased by about 60%. Individual and job match heterogeneity are important, and should be carefully modeled when estimating wage equations for the British labor market. These results are remarkably similar to the most recent evidence about these relationships in the US labor market. After extending the standard model to include industry and occupation experience, the estimated impact of job seniority becomes negligible for nonunion workers. Instead, the wages of nonunion workers rise because of the accumulation of general and sector-specific experience. The wages of union workers are still found to increase with job seniority over the first ten years with their employer, suggesting that if seniority matters for wages it is only for union workers.     

The consequences of minimum wage legislation

A policy which could raise wages in the low-wage labour market without job losses would be remarkable. Employers will respond to a wage floor not only by changing the employment level but by altering the other components of job packages. The'new economics'of the minimum wage largely ignores such effects.     

Job and wage mobility with minimum wages and imperfect compliance

We propose a job search model with minimum wage regulations and imperfect compliance to explain the doubling of the mean and variance of hourly earnings of white males during the first 18 years of labor market experience. The model encompasses job mobility and on‐the‐job wage growth as sources of wage dynamics, and is estimated by simulated generalized method of moments using data from the National Longitudinal Survey of Youths 1979. Our estimates provide a good fit for the observed levels and trends of the main job and wage mobility data, and for the increase in the mean and variance of wages over the life cycle, as well as for the fall in the fraction of workers paid below the minimum wage. Job mobility explains 40–50% of the observed wage growth. Increases in the minimum wage and/or compliance deliver small effects on the wage distribution and the nonemployment rate.

Wage equations,wage curves and all that

This paper is concerned with the relationship between wages and unemployment. Using UK regions and individuals as the basis for our analysis, the following questions are investigated. First, is the wage equation a relationship between unemployment and wages or wage changes? Second, can we identify the relationship completely by looking at regional wages and regional unemployment or do regional wages depend on aggregate unemployment as well? Third, can we identify an upward sloping cross-section relationship between wages and unemployment corresponding to a zero migration condition? Finally, are wages influenced only by the current state of the labour market or do contracts lead to wages depending on labour market conditions in the last boom or upon entry into the job?     

Within Occupation Wage Dispersion and the Task Content of Jobs

Most analyses linking task content of jobs to income inequality focus on the effects between occupations, e.g. the growing dispersion between lousy and lovely jobs. The theory, meanwhile, provides insights on links between task content of jobs and inequality also within occupations: models predict compression of wages in more routine jobs, that is those where capital is a direct substitute for labour, and an increase in dispersion in jobs where capital and labour are complements. I document that within occupations dispersion of wages is empirically relevant, as it represents around half of total wage inequality across Europe. I then link wage inequality to the task content of jobs. Using matched employee–employer data from Europe for the period 2002–14, I show that occupations where tasks complement newer technologies exhibit higher wage dispersion. This relationship is robust to adjusting for a variety of confounding and mitigating channels.     

The distributive and welfare effects of product and labour market deregulation

This paper studies the effects of product and labour market deregulation on wage inequality and welfare. By constructing an analytically tractable model in which the level of product market competition and the wages are endogenously distributed among sectors, I show that deregulation in goods market has mixed effects on inequality: the wage variance and the Gini index are lower, but the ratio of the highest over the lowest wage paid in the economy increases. Moreover, deregulation in labour markets raises the aggregate level of employment and the average real wage but reduces the welfare of trade unions in sectors with a low level of competition.     

Monopsonistic competition for the “best” workers

In this paper we analyse an economy where firms use labour as the only production factor, with constant return to scale. We suppose that jobs differ in their non-wage characteristics so each firm has monopsonistic power. In particular, we suppose that workers are heterogeneous with respect to their productivity. Then, each firm has incentives to offer higher wages in order to recruit the most productive workers. Competition among firms leads to a symmetric equilibrium wage, which is higher than the reservation wage, and to involuntary unemployment for the less productive workers, who are willing to work at the current wage but are not hired because their productivity is lower than the wage level. If firms have no institutional constraint on paying lower wages for the same job, an endogenous labour market segmentation emerges.     

Tighter labour markets to finally lift global wages

• Wage growth has been relatively slow since 2007 in advanced economies, but an upturn may be in sight. Slow productivity growth remains an issue but tighter labour markets make a positive response by wages to rising inflation more likely and there are signs that compositional and crisis‐related effects that dragged wage growth down are fading – though Japan may be an exception.
• Overall, our forecasts are for a moderate improvement in wage growth in the major economies in 2017–18, with the pace of growth rising by 0.5–1% per year relative to its 2016 level by 2018 – enough to keep consumer spending reasonably solid.
• Few countries have maintained their pre‐crisis pace of wage growth since 2007. In part this reflects a mixture of low inflation and weak productivity growth, but other factors have also been in play: in the US and Japan wage growth has run as much as 0.5–1% per year lower than conventional models would suggest.
• The link with productivity seems to have weakened since 2007 and Phillips curves – which relate wages to unemployment – have become flatter. A notable exception is Germany, where the labour market has behaved in a much more ‘normal’ fashion over recent years with wage growth responding to diminishing slack.
• ‘Compositional’ factors related to shifts in the structure of the workforce may have had an important influence in holding down wage growth, cutting it by as much as 2% per year in the US and 1% per year in the UK. There are some signs that the impact of these effects in the UK and US are fading, but not in Japan.
• The forecast rise in inflation over the next year as energy price base effects turn positive is a potential risk to real wages. But the decline in measures of labour market slack in the US, UK and Germany suggests wages are more likely to move up with inflation than was the case in 2010–11 when oil prices spiked and real wages fell.

     

Educational mismatch,wages, and wage growth: Overeducation in Sweden, 1974–2000

We examine the impact of educational mismatch on wages and wage growth in Sweden. The empirical analyses, based on cross-sectional and panel data from the Level of living surveys 1974–2000, are guided by two main hypotheses: (a) that educational mismatch reflects human capital compensation rather than real mismatch, and (b) that educational mismatch is real but dissolves with time spent in the labour market, so that its impact on wages tends toward zero over a typical worker's career. Our findings do not support these hypotheses. First, significant differences in contemporaneous economic returns to education across match categories remain even after variations in ability are taken into account. Second, we find no evidence that the rate of wage growth is higher among overeducated workers than others. Our conclusion is that the overeducated are penalized early on by an inferior rate of return to schooling from which they do not recover.     

Gender differences in early-career wage growth

In Finnish manufacturing, the gender wage gap more than doubles during the first ten years in the labour market. This paper studies the factors contributing to the gender gap in early-career wage growth. The analysis shows that the size of the gender gap in average wage growth varies with mobility status, the gap being higher with employer changes compared to wage growth within firms. Several explanations for the gender gap in wage growth based on human capital theory and theory of compensating wage differentials are considered. However, much of the gap in wage growth remains unexplained. The distributional analysis of the wage growth shows that the female wage penalty increases significantly as we move along the conditional wage growth distribution, the increase being stronger with employer changes compared to within-firm wage growth.     

Do larger severance payments increase individual job duration?

This paper analyzes the effect of severance payments on the probability of separation at given tenure, wages and other individual and firm characteristics. It studies a mandatory deferred wage scheme of the Italian labour market (Trattamento di Fine Rapporto, TFR). Deferred wages increase job duration if two conditions hold: wages are rigidly set outside the employer-employee relationship, and past provisions are accumulated at interest rates that are below market rates. Under such circumstances, workers who withdraw from their accumulated stock of unpaid wages should experience, at given tenure, a subsequent increase in the probability of separation. This prediction appears empirically robust and quantitatively sizeable. A withdrawal of 60% of the TFR stock (the median observed withdrawal) increases the instantaneous hazard rate by almost 20%. In other words, an individual with at least ten years of tenure that experiences an early withdrawal increases his/her hazard rate from 10% to about 12%. The empirical result takes into account the existence of unobserved heterogeneity and a variety of further robustness tests.     

Wages,implicit contracts,and the business cycle: Evidence from a European panel

We study the joint behavior of hours and wages over the business cycle in a unique panel of 13 European countries, and document significant history dependence in wages. Workers who experience favorable market conditions during their tenure on the job have higher wages, and work fewer labor hours. Unobserved differences in productivity, such as varying job quality, or match-specific productivity are not likely to explain this variation. The results instead point to the importance of contractual arrangements in wage determination. In economies with decentralized bargaining practices, such arrangements resemble self-enforcing insurance contracts with one-sided commitment (by the employer). On the other hand, in countries with strong unions and centralized wage bargaining, wage behavior is better approximated by full-commitment insurance contracts. The co-movement of hours and wages further confirms a contractual framework with variable worker hours. Despite the strong prevalence of contracts in Europe, however, the elasticity of labor supply is considerably smaller compared to the U.S. labor market.     

Semi-Nonparametric Estimation of an Equilibrium Search Model

We specify and estimate an equilibrium job search model with productivity differences across labour market segments. The model allows for two types of unemployment: frictional unemployment due to search frictions and structural unemployment due to wage floors. Wage floors exist because of high unemployment benefits or binding minimum wages. The productivity distribution is estimated semi-nonparametrically along the lines of Gallant-Nychka, using Hermite series approximation. We decompose the total unemployment rate and we examine the effects of changes in the minimum wage.     

Job mobility and the gender wage gap in Italy

This paper investigates the contribution of gender differences in job mobility to the emergence of a gender wage gap in the Italian labour market. We show that over the first 10 years of labour market experience job mobility accounts for up to 30% of total log wage growth for men and only 8.3% for women, and that this difference is mainly due to differences in returns to mobility. The gender mobility gap is robust to the inclusion of individual, job and firm characteristics, to different ways of accounting for individual unobserved heterogeneity, and is mainly found for voluntary job moves. Looking at the characteristics of the jobs and the firms' workers move to, we find that moves to larger firms represent by far the main source of gender differences in returns to mobility. We offer two possible explanations for this finding; one which involves differences in bargaining behaviour and one which relates to the theory of compensating differentials.     

Does citizenship matter? The economic impact of naturalizations in Germany

This paper analyses whether citizenship acquisition affects the labour market performance of immigrants in Germany. The study uses actual micro data from the employment sample of the Institute for Employment Research, which covers more than 80% of the entire labour force in Germany. The econometric analysis has been carried out using panel data techniques, which allow to disentangle the effects of self-selection and legal impact of citizenship acquisition. Estimates from a pooled OLS specification suggest the existence of a wage premium for naturalized immigrants of both genders. Fixed effects estimates for males show an increased wage growth in the years following naturalization, consistent with the argument that naturalization increases the labour market opportunities of immigrants. Results for female employees indicate that the wage premium of naturalized women is solely the result of a positive self-selection process.     

How low can U go?

• ? Although there is growing evidence that wage growth is building in response to low and falling unemployment in the advanced economies, there is scope for unemployment rates to fall further without triggering a pay surge.
• ? For a start, current unemployment rates in comparison to past cyclical troughs overstate the tightness of labour markets. Demographic trends associated with the ageing ‘baby boomer’ bulge have pushed down the headline unemployment rate – unemployment rates among older workers are lower than those of younger cohorts. And in a historical context, Europe still has a large pool of involuntary part‐timers.
• ? In addition, rising participation rates mean that demographics are less of a constraint on employment growth than widely assumed. In both 2017 and 2018, had it not been for increased activity rates (mainly for older cohorts), unemployment would have had to fall more sharply to accommodate the same employment increase. We expect rising participation rates to continue to act as a pressure valve for the labour market.
• ? Finally, unemployment rates were generally far lower during the 1950s and 1960s than now. If wages stay low relative to productivity, as was the case during that prior era, employment growth may remain strong, with unemployment falling further. In the post‐war era, low wages were partly a function of a grand bargain in which policy‐makers provided full employment in return for low wage growth.
• ? There is evidence to suggest that many post‐crisis workers have opted for the security of their existing full‐time job and its associated benefits despite lower wage growth, rather than change job and potentially earn more; the rise of the ‘gig economy’ has led some workers to value what they already have more. Put another way, the non‐accelerating inflation rate of unemployment (NAIRU) has fallen. So, the role of labour market tightness in pushing wage growth higher may continue to surprise to the downside.

     

Wage determination in late socialism: The case of Poland

Does economic transition necessitate a profound change in the inter-industry wage structure? This paper argues that principles of wage determination in centrally planned economies were not basically different from those prevailing in market economies. Even if the center became involved in wage setting, reward for human capital and the compensating differential had to be taken into consideration. Moreover, market power led to rent-sharing via wage bargaining and efficiency wages. Hence, this paper claims that wages in socialist economies were determined by similar factors to those in market economies. This is supported by comparison of inter-industry wage structures between socialist and capitalist countries and by results of the estimation of the wage equation for Poland. There is a noticeable degree of similarity in wage structures generated by both systems.I started this paper when I was a research visitor at the Centre of Economic Performance, London School of Economics and completed it when I was a visiting fellow at Princeton University.
