DOES INPUT QUALITY DRIVE MEASURED DIFFERENCES IN FIRM PRODUCTIVITY?*

One explanation for productivity dispersion is that the quality of inputs differs across firms. We add labor market history variables such as experience and firm and industry tenure, as well as general human capital measures such as schooling and sex. Adding these variables decreases the ratio of the 90th to 10th productivity quantiles from 3.27 to 2.68 across eight Danish manufacturing and service industries. We also use the wage bill and worker fixed effects. We find that the wage bill explains as much dispersion as human capital measures.     

What is behind low wages in central and eastern Europe?

This paper compares wages across Europe in relation to the characteristics of workers and firms, with a particular focus on wage levels in central and eastern European countries. Worker and workplace endowments can be taken as a proxy for labour productivity. We estimate the extent to which wage differences observed at an aggregate level can be related to the different compositions of workforces and workplaces, as well as the types of jobs conducted in separate countries. We also decompose the observed differences in returns on endowments by identifying the sectors and occupational categories that contribute most to the wage gaps observed at the aggregate level. The wage gaps in low-wage countries actually appear larger once differences in worker, work and workplace characteristics are controlled for. In contrast, the differences in wages between high-wage countries diminish when we control for these endowments. The wage gap between East and West thus seems to be explained by a much lower return on skills and other characteristics rather than by differences in the composition of workforces and firms. Sectoral and occupational analysis suggests that central and eastern European countries have developed a generalised low-cost and low-wage model, with relative returns particularly low on higher skills. There is much less wage disparity across European countries in more labour intensive and lower-paid services sectors, such as accommodation and food service activities. The magnitude of the wage gap seems to be driven by the relative position of sectors and occupations in high-wage countries.     

PRODUCTIVITY GROWTH AND WORKER REALLOCATION*

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. An equilibrium model of growth and firm evolution designed to clarify the role of worker reallocation in the growth process is studied. We show that it explains the correlations between size measures and labor productivity found in Danish firm data. Conditions under which the reallocation of workers from less to more productive firms contributes to aggregate productivity growth in the economy modeled are derived. Finally, a proof of existence of an equilibrium solution to the model is also provided.     

Social Preferences, Skill Segregation, and Wage Dynamics

We study the earning structure and the equilibrium assignment of workers to firms in a model in which workers have social preferences, and skills are perfectly substitutable in production. Firms offer long-term contracts, and we allow for frictions in the labour market in the form of mobility costs. The model delivers specific predictions about the nature of worker flows, about the characteristics of workplace skill segregation, and about wage dispersion both within and across firms. We show that long-term contracts in the presence of social preferences associate within-firm wage dispersion with novel "internal labour market" features such as gradual promotions, productivity-unrelated wage increases, and downward wage flexibility. These three dynamic features lead to productivity-unrelated wage volatility within firms.     

Training, search and wage dispersion

This paper combines on-the-job search and human capital theory to study the coexistence of firm-funded general training and frequent job turnovers. Although ex ante identical, firms differ in their training decisions. The model generates correlations between various firm characteristics that are consistent with the data. Wage dispersion exists among ex ante identical workers because workers of the same productivity are paid differently across firms, and because workers differ in their productivity ex post. Endogenous training breaks the perfect correlation between work experience and human capital, which yields new insights on wage dispersion and wage dynamics.     

PRIVATIZATION IN CHINA: TECHNOLOGY AND GENDER IN THE MANUFACTURING SECTOR

This paper examines the impact of privatization on gender discrimination in China across firms with different technology intensities. Using a comprehensive firm‐level survey, the paper identifies gender wage‐productivity differentials by directly estimating the relative productivity levels of workers from the production function of firms. The panel structure of the survey is taken advantage of by following firms that were fully state‐owned in the initial year, and distinguishing them from firms that were later privatized. The main results show that privatization was associated with an increase in relative productivity of female workers in high technology industries, and a reduction in relative productivity of female workers in low technology industries. Time varying coefficient results suggest that the improvements in gender outcomes in high technology industries may not be maintained in the long run as the relative wage and productivity ratios tend to deteriorate, potentially due to low supply of highly educated female workers. At the same time, outcomes in privatized low technology industries increase over time, lowering the wage and productivity gaps between male and female workers. (JEL J16, J31, P20)     

Worker flows, job flows and firm wage policies

Like many transition economies, Slovenia is undergoing profound changes in the workings of the labour market with potentially greater flexibility in terms of both wage and employment adjustment. To investigate the impact of these changes, we use unique longitudinal matched employer‐employee data that permits measurement of employment transitions and wages for workers and enables links of the workers to the firms in which they are employed. We can thus measure worker flows and job flows in a comprehensive and integrated manner. We find a high pace of job flows in Slovenia especially for young, small, private and foreign‐owned firms and for young, less educated workers. While job flows have approached the rates observed in developed market economies, the excess of worker flows above job flows is lower than that observed in market economies. A key factor in the patterns of the worker and job flows is the determination of wages in Slovenia. A base wage schedule provides strict guidelines for minimum wages for different skill categories. However, firms are permitted to offer higher wages to an individual based upon the success of the worker and/or the firm. Our analysis shows that firms deviate from the base wage schedule significantly and that the idiosyncratic wage policies of firms are closely related to the observed pattern of worker and job flows at the firm. Firms with more flexible wages (measured as less compression of wages within the firm) have less employment instability and are also able to improve the match quality of their workers.

The Role of Expectation on Job Search and the Firm Size Effect on Wages

We formulate dynamic games which give a rationale to the firm size–wage effect that the sheer firm size increases wages. We postulate that past wages of large firms are known to new employees, while those of small firms are not. Large firms can credibly induce workers to expect high future wages and reduce turnover, while small firms have no choice but to be myopic and pay low wages. The equilibrium wage differential obtains under the same worker characteristics and production function. We provide empirical evidence that workers' expectations depend on firm size and affect wages as predicted by our model.     

Unobserved Individual and Firm Heterogeneity in Wage and Job‐Duration Functions: Evidence from German Linked Employer–Employee Data

Abstract. We analyse the correlations between individual and firm fixed effects, and wage and job‐duration functions. Our results for large firms suggest that low‐wage firms tend to be stable firms, suggesting that lower wages can buy job stability. Furthermore, high‐wage workers sort into the stable low‐wage firms. Our interpretation is that high‐wage workers have a higher wage to insure against job loss and can afford more easily to forgo wages in favour of job stability. This may provide an explanation of the puzzle identified in previous literature that high‐wage workers are matched to low‐wage firms.     

Corporate Tournaments, Human Capital Acquisition, and the Firm Size–Wage Relation

This paper provides a possible explanation for the empirically observed size–wage effect and inter-industry wage differences. It develops a model in which incentives for workers to accumulate general human capital are provided by corporate tournaments, where workers with the highest level of general human capital win promotions. Given that the prizes in such tournaments are determined by outside market conditions, the investment and the equilibrium wages depend on firm and industry characteristics. The model implies that workers in bigger firms and in more technology intensive and profitable firms and industries acquire more human capital and receive higher wages and benefits.     

Inter-Industry Wage Differentials in Greece: Evidence from Quantile Regression Analysis

Using a consistent estimator of the covariance matrix of the asymptotic distribution of the quantile regression estimator with intra-cluster correlation of the error terms, the paper investigates whether and to what extent inter-industry wage differentials derive from worker heterogeneity in the form of unobserved quality. To conduct this study, we pioneer in utilizing a unique data set, the European Union Structure of Earnings Survey for Greece, which follows a two-stage random sampling approach of employees clustered within firms. Data refer to 2010 when the first elements of the economic adjustment programme to deal with the chronic deficiencies of the Greek economy and restore sustainable public finances, competitiveness and set the foundation for long-term growth, gained visibility. Results point to high wage dispersion across industries at the mean of the conditional wage distribution, even after controlling for personal and workplace characteristics. However, evidence for the unobserved heterogeneity hypothesis is rather scant. Therefore, there is room for efficiency wage or rent-sharing theories in accounting for a large part of inter-industry wage differentials tentatively implying that firm heterogeneity in the ability to pay matters more than employee unobservable attributes in the wage determination process.     

Equilibrium Wage Dispersion,Firm Size,and Growth

This paper analyzes a model of equilibrium wage dynamics and wage dispersion across firms. It considers a labor market where firms set wages and workers use on-the-job search to look for better paid work. It analyzes a perfect equilibrium where each firm can change its wage paid at any time, and workers use optimal quit strategies. Firms trade off higher wages against a lower quit rate, and large firms (those with more employees) always pay higher wages than small firms. Non-steady-state dispersed price equilibria are also analyzed, which describe how wages vary as each firm and the industry as a whole grow over time.

Wage/tenure contracts with heterogeneous firms

This paper investigates equilibria where firms post wage/tenure contracts and risk averse workers search for new job opportunities whether employed or unemployed. We generalize previous work by assuming firms have different productivities. Equilibrium implies more productive firms always offer more desirable contracts. Thus workers never quit from more productive firms for less productive firms. Nevertheless turnover is inefficient as employees with long tenures at low productivity firms may reject outside job offers from more productive firms. A worker who quits to a more productive firm may accept a wage cut. Such wage cuts are compensated by faster “promotion” rates to higher wage levels in the future. We also generalize previous arguments by showing equilibria exist where the distribution of offers contains interior mass points and find equilibrium wage/tenure contracts need not be smooth.     

DOES WAGE DISPERSION MAKE ALL FIRMS PRODUCTIVE?

This article puts the relationship between wage dispersion and firm productivity to an updated test, taking advantage of access to detailed Belgian linked employer–employee panel data. Controlling for simultaneity issues, time‐invariant workplace characteristics and dynamics in the adjustment process of productivity, empirical results reveal the existence of a positive impact from conditional intra‐firm wage dispersion to firm productivity (measured by the average value added per hour worked), which however decreases for higher dispersion levels. Findings thus suggest that the incentive effect of wage dispersion, predicted for instance by the ‘tournament’ model, dominates ‘fairness’ and/or ‘sabotage’ considerations. Further results reveal that the influence of wage dispersion on firm productivity is stronger among firms with a larger proportion of highly skilled workers but does not depend on whether wages are collectively renegotiated at the firm level.     

Wage,foreign-owned firms,and productivity spillovers via labour turnover: a non-linear analysis based on Chinese firm-level data

Using firm-level panel data from Chinese manufacturing firms over the period 2004–2007, this article investigates the impact of the wage gap between local and foreign-owned firms on foreign direct investment (FDI) spillovers in terms of total factor productivity (TFP). We find a non-linear threshold effect that: a low-level wage gap threshold exists, below which FDI spillovers are significantly negative. This is because FDI spillovers via labour turnover are blocked due to the low wages of local firms, which jeopardizes the flow of skilled workers from foreign firms to local firms. In contrast, when the wage gap reaches a high-level threshold, local firms can get benefits from FDI spillovers. The reason is that high wages of local firms attract skilled employees to leave foreign firms, which yields a large magnitude of worker mobility from foreign firms to local firms. Our article provides evidence that labour turnover as the channel of FDI spillovers only works when the wage gap is beyond some threshold. Also, these thresholds vary across regions and firm ownerships.     

Minimum Wages and Firm Productivity: Evidence from Vietnamese Manufacturing Firms

ABSTRACT

This paper empirically examines the minimum-wage impact on firm productivity. Using a detailed Vietnamese firm-level dataset from 2010 through 2015, the regression results suggest that firms raise their labor productivity, total factor productivity, capital intensity and revenue in response to increased minimum wage standards. Firms that pay their workers below the minimum wage react more positively in raising their labor productivity than high-wage firms. Minimum wages has had a more pronounced impact on firms’ labor productivity, total factor productivity and capital intensity since the uniform wage rate was introduced for both domestic private and foreign-invested enterprises in 2012.     

Intermediate good sourcing,wages and inequality: From theory to evidence

This paper examines the consequences of offshoring and outsourcing on domestic wages and wage inequality. I highlight the role of labor market frictions in impacting firms’ outsourcing and offshoring decisions; specifically, how differential costs of matching with workers affect the location of production (onshore or offshore) and how differential costs of assessing worker quality affect the ownership of intermediate production (intra‐firm or inter‐firm). I demonstrate how firm sourcing decisions can depend crucially on the industry skill intensity, which reflects the importance of worker–firm match quality, and as a result, the effect of offshoring on domestic labor depends on occupation and industry characteristics, as well as the ownership regime of trade. Bringing the theory to the data I rely on plausibly exogenous variation in the cost of inter‐ and intra‐firm offshoring to identify the effects of a change in each type of offshoring on domestic wages. I find strong evidence that the effect of offshoring on domestic wages—both on the average and on the wage distribution—is governed by the type of offshoring (inter‐ vs. intra‐firm), the skill intensity of the industry, and the offshorability of the occupation.     

Under-reporting of Income and Labor Market Performance

To examine the effects on labor market performance of government tax and enforcement policies, this paper develops an equilibrium model featuring tax evasion, matching frictions, and worker–firm wage bargains. In the wage bargains, workers and firms can agree on the amount of remuneration that should not be reported to the tax authorities. We find that increased taxation actually reduces unemployment, whereas more zealous enforcement has the opposite effect.     

Foreign-owned firms around the world: A comparative analysis of wages and employment at the micro-level

This paper provides the first microeconomic cross-country analysis of the effects of foreign ownership on wages, employment and worker turnover rates. Using firm-level and linked worker-firm data, we apply a standardised methodology for three developed (Germany, Portugal, UK) and two emerging economies (Brazil, Indonesia). We find that wage effects are larger in developing countries, and that for each country the largest effect on wages comes from workers who move from domestic to foreign firms. Employment growth after foreign takeover is concentrated in high-skill jobs. In contrast to widespread fears, there is no evidence that wage gains come at the expense of greater job insecurity; separation rates actually fall slightly after takeover. We conclude that the positive effect of foreign ownership on wages is not primarily driven by its impact on incumbent wages, but by its impact on the creation of high-wage jobs.     

Micro Foundations for Wage Flexibility: Wage Insurance at the Firm Level*

To what extent do firms insulate their workers' wages from fluctuations in product markets? Which firm and worker attributes are associated with wage flexibility at the micro level? We first rely on Guiso, Pistaferri and Schivardi (2005) to estimate dynamic models of sales and wages, finding that in Portugal, workers' wages respond to permanent shocks on firm performance, as opposed to transitory shocks. We then explore the factors associated with wage flexibility, finding that collective bargaining and minimum wages are associated with higher wage insurance by the firm, while the threat of firm bankruptcy reduces it. Managers receive less protection against permanent shocks than other workers.
