WAGE DIFFERENTIALS ACROSS LABOR MARKETS AND WORKERS: DOES COST OF LIVING MATTER?

Wage differential studies rarely account for interarea differences in cost of living, owing both to data limitations and theoretical ambiguity. This study develops a price index for 185 metropolitan areas comprising about 70% of the U.S. labor force. Current Population Survey data for 1985–95 and data on site-specific amenities are used to estimate earnings differentials based on nominal wages, wages fully adjusted for measured cost of living, and a simple approximation of "real" wages with partial adjustment for price-level differences. Dispersion in approximate real wages across 185 labor markets and differentials by region and city size are substantially lower than dispersion in nominal or full adjustment wages. Estimates of racial and ethnic differentials display moderate sensitivity to choice of a wage measure, whereas other standard differentials do not. Both nominal wages and wages fully adjusted for cost of living may provide misleading estimates of real wage differentials. Absent data on interarea prices and amenities, researchers should include detailed controls for region and city size in nominal wage equations. ( JEL J31, R23)     

Uncertainty and front-end loading of labor agreements

Uncertainty of future prices is offered as an explanation for front-end loading of real wages in nominal wage contracts. Exploitation of mutually beneficial gains from trade between risk-neutral employers and employees implies an expected future real wage that is lower the greater is the uncertainty of future prices, and the observed extent of front-end loading is consistent with plausible values of uncertainty of future prices. I would like to thank, without implicating, M. L. Burstein, George Fallis, and an anonymous referee for helpful comments.     

The 2011 Industrial Relations Reform and Nominal Wage Adjustments in Greece

This study investigates nominal contractual base-wage adjustments in Greece associated with the 2011 industrial relations reform which re-defined the limits within which base wages could oscillate and allowed workers’ associations to negotiate for wages at the firm level. The assessment covers the period 2010–2013 and is based on information extracted from the universe of firm-level contracts signed in this period. We found that firm-level contracts increased dramatically shortly after the reform, now covering a larger pool of workers, especially in larger firms, and are associated with higher base-wage reductions in the post-reform period. At the firm level, wage reductions are higher when workers are represented by a workers’ association rather than a typical trade union. In addition, a heterogeneous effect is uncovered regarding the factors that shape base-wage adjustments (firm size, profitability, structure of bargaining body and aggregate unemployment) between new and traditional forms of workers’ representation in collective bargaining.     

WAGES,EMPLOYMENT, AND STATISTICAL DISCRIMINATION: EVIDENCE FROM THE LABORATORY

We report results from laboratory experiments designed to examine statistical discrimination. Our design expands upon existing research by generating data both on wage contracts and unemployment rates of directly competing worker groups. We find some evidence for statistical wage discrimination against workers having an identical expected productivity but a higher productivity variance. However, those same subjects are less likely to be unemployed, suggesting that our employer‐subjects view hiring choice and wage contracts as substitutable. A clear implication is that field data discrimination estimates based on wages alone may overestimate the true impact of such discrimination. (JEL C90, J71)     

INFLATION AND WAGE RIGIDITY/FLEXIBILITY IN THE SHORT RUN

A recent literature uses accurate wage data from payroll records and provides compelling evidence against the conventional belief that nominal wages are downward sticky. This paper provides a unique contribution to this literature by conducting a formal analysis of the role of inflation in cyclical wage rigidity/flexibility. Analysis of payroll‐based wage data from the Korean labor market for the period 1971–2014 finds that the degree of downward nominal wage flexibility is countercyclical, and the countercyclicality becomes stronger during a deflationary, relative to inflationary, recession. This serves as a counter‐example to the conventional theory of cyclical wage rigidity. (JEL E24, E32, J30, J64)     

THE RELATIVE STICKINESS OF WAGES AND PRICES

While many modern business cycle theories posit the existence of nominal wage and/or output price stickiness, their relative importance remains an unsettled issue. Using a structural VAR model, this paper exploits evidence on the behavior of real wages to assess the relative importance of these two sources of stickiness. The empirical results suggest that a positive shock to aggregate demand causes a significant temporary fall in real wages. This is taken as evidence that sticky wages have played a more important role than sticky prices in transmitting aggregate demand shocks to real economic activity in the post-war U.S. (JEL E32)     

A Note on Dual Internal Labor Markets and Wages of Temporary Workers: Evidence from Linked-Employer-Employee Data

I use linked employer-employee data from the German Federal Statistical Office to estimate within-firm wage differentials between temporary workers with fixed-term contracts and workers with permanent contracts in the context of dual internal labor markets. Wage-tenure profiles of permanent workers are estimated separately for each firm to obtain a proxy for the prevalence of internal labor markets. Temporary workers earn significantly lower wages in firms with steeper wage-tenure profiles. This finding is consistent with the segmentation in a primary permanent workforce with high wages and a secondary temporary workforce with low wages, if internal labor markets are more prevalent.     

The (unexpected) structure of “rents” on the French and British labour markets

This paper considers the allocation of labour on the French and British markets, using objective wage and subjective satisfaction data. We show that, in some sectors, workers enjoy both higher wages and higher job satisfaction. We argue that this reflects labour market wage rents. Perhaps surprisingly, wage rents are typical of the British public sector and permanent contracts, but not of their French counterparts. In France, such rents are found in full-time, rather than part-time jobs. Hence, the data provide little support for the usual a priori that the French labour market is structured along insider–outsider model lines, whereby wage rents are captured by the insiders of the public sector to the detriment of the private sector. However, they do suggest that part-time employment is involuntary to a far greater extent in France than in Great Britain.     

Unions and wage inequality

Summary and Conclusions The impact of unions on the structure of wages has recently attracted renewed interest as analysts have struggled to explain the rise in earnings inequality in several industrialized countries. Canada, the United Kingdom, and the United States provide a potentially valuable set of countries for examining this question. All three countries now collect comparable data on wages and union status in their regular labor force surveys. Several features of the collective bargaining institutions of these countries make them suitable for studying the relationship between unions and wage inequality. Bargaining is highly decentralized; there are no general mechanisms for extending collective bargaining provisions beyond the “organized” sector; and the fraction of the work force covered by collective bargaining is relatively modest. Thus it is possible to compare the structure of wages for workers covered by union contracts to those who are not covered, and potentially infer the effect of unions on overall wage inequality.     

THE CHANGING RESPONSIVENESS OF WAGES TO PRICE-LEVEL SHOCKS: EXPLICIT AND IMPLICIT INDEXATION

The article provides evidence for the U.S over the period 1961-84 that the responsiveness of nonunion wages to price-level shocks changes through time much as the degree of indexation in union contracts does, suggesting that there exists implicit as well as explicit indexation. When coupled with the result from previous research that indexation responds positively to inflation uncertainty, the findings indicate that greater inflation uncertainty may lead to reduced overall wage rigidity. In the context of a rational expectations model with long-term wage contracts, a decline in the effectiveness of an activist monetary policy could result.     

CYCLICAL COMOVEMENTS IN INDUSTRIAL LABOR AND PRODUCT MARKETS: THEORY AND EVIDENCE

We establish the theoretical connection between industrial labor and product markets within the contractual wage-rigidity new Keynesian explanation of business cycles. We estimate time-series and cross-sectional regressions for 28 private two-digit (S.I.C.) industries and find: (i) greater uncertainty is associated with upward flexibility of the nominal wage and moderates the countercyclical response of the real wage to aggregate demand shocks; (ii) an upwardly rigid nominal wage response to energy price shocks reduces the real contractionary effects of these shocks; (Hi) downwardly inflexible nominal wages are associated with downwardly rigid prices in response to productivity shocks.     

On‐the‐job training in Europe: Determinants and wage returns

Using data from the European Community Household Panel on six countries over the period 1995–2001, this article investigates the determinants of workers’ participation in training activities and the effects of training on wages. Based on measures of four distinct training types, the authors find that while OLS estimates yield significant wage returns to training for nearly all of the countries, fixed‐effects estimations show returns to be not statistically different from zero. This suggests that wage returns to training might be overstated due to failure to take adequate account of the correlation of training with confounding factors that affect wages.     

MONEY, CREDIT, and WAGES IN HYPERINFLATION: POST-WORLD WAR I GERMANY

An important feature of the German hyperinflation is the way in which accelerating monetization of both government and private debt by the Reichsbank fueled the inflation process. The stimulus to private credit demand arising from more rapid adjustment of money wages over this period is often ignored, however. The present empirical results strongly support the importance of wage pressures in augmenting fiscal influences on nominal money growth during 1920–1923. Our findings also suggest that wage claims provided the main conduit through which higher inflationary expectations were accommodated by faster rates of monetary expansion.     

A COMPETITIVE MODEL OF WORKER REPLACEMENT AND WAGE RIGIDITY

We adapt the models of Menzio and Moen (2010) and Snell and Thomas (2010) to consider a labor market in which firms can commit to wage contracts but cannot commit not to replace incumbent workers. Workers are risk averse, so that there exists an incentive for firms to smooth wages. Real wages respond in a highly nonlinear manner to shocks, exhibiting downward rigidity, and magnifying the response of unemployment to negative shocks. We also consider layoffs and show that for a range of shocks labor hoarding occurs while wages are cut. We argue these features are consistent with recent evidence. (JEL E32, J41)     

EFFICIENCY WAGES AND SUBJECTIVE PERFORMANCE PAY

This paper studies optimal relational contracts in motivating workers in a market setting. We find that labor markets with higher turnover costs will use more subjective performance pay and less efficiency wages and that in those markets, the total wage payment is lower and the equilibrium employment level is higher. Surprisingly, under certain conditions, an increase in turnover costs leads to higher social welfare. Incorporating workers' search costs, we show that wages are procyclical in booms and are either rigid or countercyclical during recessions. The predictions of the model are consistent with some empirical evidence. ( JEL D82, J33, J41, J63)     

Motherhood Penalties and Living Arrangements in China

Past research on the “motherhood wage penalty” has been based on data from nuclear families, leaving open the possibility that the motherhood wage penalty may be lower or even absent in multigenerational families. In this article, the wage gap between mothers and nonmothers is examined in nuclear and multigenerational families in the context of contemporary China, which has a long tradition of patriarchal families. Using 1993 to 2006 China Health and Nutrition Survey data, the magnitude and variation of motherhood penalty is explored with fixed effects models among 1,058 women. The results show that each additional child lowers hourly wages by about 12%. In addition, the motherhood penalty is largest for women living with their husbands' parents, smaller for women not living with parents, and nil for women living with their own parents.     

Wage and nonwage outcomes in collective bargaining: Determinants and tradeoffs

Using unskilled labor wage rates and union contract scores derived from a sample of 500 U.S. manufacturing contracts, this study finds that in 1975 there was considerable variation in unions’ abilities to deliver higher wages and desirable nonwage contractual provisions to their members (though it is clear that the stronger unions have bargained high levels of both wages and nonwage items). There are a variety of union power, employee quality, union preference, and employer cost variables which impact upon the bargaining choices made between wages and nonwage provisions, and it appears that union strength tilts the compensation package toward wages. The authors, associate professors at the University of Illinois, are very grateful to Christopher Pawlowicz, Ronald Seeber, and Roger Wolters for their help in gathering data. They also are grateful to the Office of the Assistant Secretary for Policy, Evaluation and Research of the U.S. Department of Labor and to the Research Board of the University of Illinois for financially supporting this research. Such support in no way implies, however, that the Department or the University endorses the methods or conclusions in this study.     

The Effects of Prevailing Wage Laws: A Comparison of Individual Workers'' Wages Earned on and off Prevailing Wage Construction Projects

I evaluate the effects of prevailing wage laws using a unique data set that shows the wages paid to workers on prevailing wage projects and the wages paid to the same workers during the same time period for work on projects not covered by prevailing wage regulations. The wage comparison shows that workers are generally paid more for work on prevailing wage projects than they are for work on non-prevailing wage projects. Thus, prevailing wage laws likely do increase the cost of public construction. In addition, to the extent that the quality of construction is improved, prevailing wage laws appear to be an inefficient mechanism by which to achieve additional quality, as the regulations often result in workers being paid more than they earn in the private market.     

ASYMMETRY IN THE EFFECTS OF MONETARY AND GOVERNMENT SPENDING SHOCKS: CONTRASTING EVIDENCE AND IMPLICATIONS

Using quarterly data for the United States, demand contraction exceeds expansion in the face of monetary and government spending shocks. Demand contraction in the face of government spending shocks, is absorbed in nominal wage and price deflation. The variability of government spending shocks decreases average wage and price inflation. In contrast, the upward flexibility of price appears in sharp contrast to its downward rigidity in the face of monetary shocks. Furthermore, output contraction is notably larger relative to expansion in the face of monetary shocks. Monetary variability accelerates average price inflation and decreases average output and real wage growth.     

From wage rigidity to labour market institution rigidity: A turning-point in explaining unemployment?

In this paper we offer a critical discussion about the concept of labour market rigidity in the light of recent theoretical approaches that have aimed to provide sound micro-foundations to the presence of unemployment in market economies. We point out that the concept of labour market rigidity usually referred to in such theories has changed over time, involving in succession the rigidity of wages, contracts and labour market institutions. We also appraise the factors that lead labour market institutions rigidity, stressed by the search literature, to challenge the more widespread explanation of unemployment grounded on wage rigidity. Moreover, we analyse some theoretical and empirical issues that cast doubt on the ability to deal with unemployment, disentangling the role of institutional rigidities from that of wage stickiness.
