Regional Efficiency Wages: Are They a Source of Real Earnings Differentials?

This paper investigates the role of spatial efficiency wage premiums as a partial explanation for both inter-industry and geographic wage differentials. The empirical approach is based on an analysis of panel data for six select manufacturing industries operating within specific (U.S.) states. Besides testing for the existence of a regional "wage curve," this research adds to the evidence on traditional determinants of spatial wage differentials. An explicit treatment of regional cost-of-living conditions is unique to the analysis; also, industry wage structures are accounted for in explaining regional wage differences. The findings here contribute to an initial body of evidence on regional efficiency wages. The empirical evidence indicates that the relationship between regional wages (nominal or real) and the local unemployment rate is much more complex than implied by the wage curve.     

Managers and Wage Policies

Do individual top managers matter for wages and wage policies? Are there general differences in “style” among managers with respect to worker compensation? To shed light on these questions, we exploit a large panel dataset from Portugal that allows us to match workers, firms, and managers, and follow the movements of the latter across different firms over time. While accounting for the effect of worker and firm heterogeneity, we estimate the role of top manager fixed effects in determining wages and wage policies. The estimates suggest that (i) top managers have a significant influence on wages and wage policies; (ii) there exists different managerial “styles”; and (iii) managers’ (observable) attributes matter for worker compensation.     

Wage incentives and wage rigidity: A representative view from within

A recent literature has used surveys of those who set wages to learn about the nature of wage incentives and the sources of wage rigidity. Methodologically, we overcome many of the objections that have been raised against this work. Substantively, we find that: (i) the reasons for real wage rigidity differ significantly between large and small firms, and between the high- and low-end of the labor market; (ii) efficiency wage mechanisms reinforce rigidities due to worker bargaining power; (iii) money illusion is a widespread phenomenon across all segments of the labor market; (iv) unions reinforce nominal wage rigidities due to external pay comparisons; (v) there appears to be gender differences in pay bargaining and work morale.     

Firm heterogeneity and wages in unionised labour markets: Theory and evidence

In many countries wages are set in two stages, where industry-level collective bargaining is followed by firm-specific arrangements determining actual paid wages as a mark-up on the industry wage floor. What explains the wage set in each of these stages? In this paper we show that both the industry wage floor and the average wage cushion are systematically associated with the degree of firm heterogeneity in the industry: The former (latter) is negatively (positively) associated with the productivity spread. Furthermore, since the response of the wage floor dominates that of the wage cushion, workers in more heterogeneous industries tend to get lower actual paid wages. These conclusions are reached in a model of Cournot oligopoly with firm productivity heterogeneity and a two-tiered wage setting system. They are then confirmed by administrative data covering virtually all workers, firms and collective bargaining agreements of the Portuguese private sector for the period 1991–2000.     

Paying to queue: a theory of locational differences in nonunion wages

Traditional theories of the effect unions have on nonunion wages are difficult to reconcile with firm and worker mobility. We show how differences in nonunion wages can persist in a two-city search model. Nonunion wage differences across cities are driven by transition rates into the union sector. Should union queues form in the nonunion sector, union power decreases nonunion wages as workers are willing to take lower wages to line up for union jobs. However, if queues are formed in the unemployed sector, union power increases nonunion wages as nonunion firms pay premiums to induce workers to leave the queue.     

The determination of wages of newly hired employees: Survey evidence on internal versus external factors

This paper reports findings on the relative importance of internal versus external factors in the setting of wages of newly hired workers. The evidence, from a rich firm-level survey on wage and price-setting procedures in 15 European Union countries, suggests that external labour market conditions are less important than internal pay structures in determining hiring pay, with internal pay structures binding even more often when there is labour market slack. When explaining their choice firms allude to fairness considerations and the need to prevent a potential negative impact on effort. Cross-country differences are found to depend on institutional factors: countries in which collective agreements are more prevalent and collective agreement coverage is higher report more often internal pay structures as the main determinant of hiring pay. Within-country differences are found to depend on firm and workforce characteristics: there is a strong association between the use of external factors in hiring pay, on the one hand, and skills (positive) and tenure (negative) on the other.     

Who Benefits from Marriage?*

The phenomenon that married men earn higher average wages than unmarried men – the marriage premium – is well known. However, the robustness of the premium across the wage distribution and the underlying causes of the marriage premium are unclear. Focusing on the entire wage distribution and employing recently developed semi‐non‐parametric tests for quantile treatment effects, our findings cast doubt on the robustness of the premium. We find that the premium is explained by selection above the median, whereas a positive premium is obtained only at very low wages. The causal effect at low wages may be attributable to employer discrimination.     

The structure of wages during the economic transition in Romania

I use cross-sectional individual data from the 1994 Integrated Household Survey (IHS) of Romania to analyze the determinants of male and female wages in public and private enterprises. Using quantile regression I estimate the rate of return to education and experience at different quantiles of the wage distribution. Higher levels of education are significantly associated with higher wages for both males and females in public firms. In private firms, only college education is correlated with significantly higher wages. I also find that there are no significant differences in the returns to human capital at the median and at the upper and lower tail of the distribution of gender-specific wages in each sector. Differences in individual characteristics are found to explain the highest portion of the male–female wage differential in Romania in both sectors.     

The national internal labor market encounters the local labor market: Effects on employee retention

Formal salary systems are commonplace among medium to large-sized firms and within the United States government. However, there is little evidence regarding the costs, if any, of such systems. This study analyzes the effects on retention within the United States Air Force from an inflexible wage system failing to adequately compensate personnel for local compensating wage differentials. Using location-specific Air Force personnel records, I compare the differences between military and civilian wages, by occupation, across locations to determine if local labor markets play a significant role in the stay or leave decisions for personnel. Results show that rigid wage constraints do in fact impose costs on the firm through increased turnover in locations that fail to adequately adjust wages for the cost of living and amenities.     

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.

     

Wage-setting institutions as industrial policy

Centralized wage-setting arrangements compress wage differentials along many dimensions, but how do they affect employment structure? To address this issue, we relate the evolution of US–Swedish differences in the industry distribution of employment to relative wages between and within industries. We find that centralized wage setting shifted Swedish employment away from industries with high wage dispersion among workers, a high mean wage and, especially, a low mean wage. The dissolution of Sweden's centralized wage-setting beginning in 1983 led to widening wage differentials and a reversal in the evolution of US–Swedish differences in industry structure.     

Migration and the wage and unemployment gaps between urban and non-urban sectors: A dynamic general equilibrium reinterpretation of the Harris–Todaro equilibrium

This paper offers a dynamic general equilibrium reinterpretation of the static partial migration equilibrium by Harris and Todaro [Harris, J., Todaro, M., 1970. Migration, unemployment and development; a two-sector analysis. American Economic Review 60, 126–142], under (i) flexible urban and rural wages and (ii) free mobility of workers and free entry of firms. The proposed model accounts for the set of stylized facts in developing countries: rural to urban migration and higher urban wages and unemployment.The model allows us to view the wage gap as a compensating differential for the negative amenities associated with job destruction and subsequent costly search on the consumption side, which can also be seen as a match-specific premium based on a sectoral productivity differential on the production side. Our model predicts the comovements among urban and non-urban wages and migration flows to the urban sector, an empirical regularity observed over the urbanization process of developing economies. Finally, we also conduct a welfare analysis.     

Stereotypes, Asian Americans, and Wages: An Empirical Strategy Applied to Computer Use at Work

This article examines the effect on wages of the Asian-American stereotype as mathematically and technically adept, and the role this stereotype may play in explaining racial wage differences. We propose an empirical strategy to examine the influence of stereotypes on labor market outcomes, with a specific application to the wage premium associated with computer use at work. Using Current Population Survey data, ordinary least squares estimates do not provide compelling evidence that a positive stereotype affects wages for Asian Americans.     

The effects of free trade agreements on regional wages in China

We empirically study the effects of free trade agreements on regional wages in China using Redding and Venables’ (2004) extended model and manufacturing firm-level data in China from 2000 to 2007. We show that although free trade agreements can, in general, increase firms’ average wage level, they also contribute to increasing the wage gap in China. We also find that free trade agreements can have different effects on firms’ wages across China. In particular, they have stronger effects on average wage levels in land border regions than in coastal regions. Moreover, although firms in land border regions may be located closer to the partner countries of free trade agreements, they may still prefer to use shipping to transport goods. Our findings have important policy implications. In particular, we suggest that free trade agreements with China’s western neighbors should be accompanied by the development of appropriate land transportation networks. Moreover, income tax policy regimes should be differentiated across regions in China.     

Should managerial delegation contracts be made before or after union wage setting? A game‐theoretic analysis

This paper analyzes a multiple‐stage game in which, at the final stage, two (managerial) firms compete over quantities in the product market. Prior to this stage, firm‐specific unions set the workers' wages, while the owners of both firms hire managers and provide them with incentive contracts. Owners can freely decide to arrange the managerial contract before or after the (non‐managerial) wage determination stage. Hence, the endogenous choice of the incentive contract stage is derived. The possibility of multiple equilibria arises, where both owners choose managerial contracts before or after unions' wage setting, crucially depending on unions' preferences. Such results also prove to be true for a remarkable degree of asymmetry in preferences over wages vis‐à‐vis employment across unions.     

How do European firms adjust their labour costs when nominal wages are rigid?

Although workers' nominal wages are seldom cut, firms have multiple options available if they require adjustments in their wage bills. We broaden the analysis of relative (in)flexibility in labour costs by investigating the use of other margins of labour cost adjustment at the firm level beyond base wages. Using data from a unique survey, we find that European firms make extensive use of other components of compensation to adjust the cost of labour. Interestingly, firms facing base wage rigidity are more likely to use alternative margins of labour cost adjustment; therefore there appears to be some degree of substitutability between wage flexibility and the flexibility of other cost components. Changes in bonuses and non-pay benefits are some of the potential margins firms use to reduce costs. We also show how the margins of adjustment chosen are affected by unionisation and firm and worker characteristics.     

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.     

Do inter-city differences in intra-city wage differentials have any interesting implications?

Recent research has related characteristics of cities to differences in the distribution of wages across workers with different skill levels. We demonstrate that these differences in wage differentials arise naturally as a compensating variation in Rosen’s theoretical model of inter-city wages. For example, if the income elasticity of demand for housing services is less than unity, cities with higher house prices will have smaller money wage differentials between low and high skill workers. This result has no implications for differences in either absolute or relative real productivity or welfare of unskilled workers. Similarly, changes in the amenity of an urban area may result in changes in relative wages of skilled and unskilled workers with no implications for real productivity or welfare differentials.Empirical tests in which housing cost differentials are added as a determinant of inter-city differences in an intra-urban wage differential model provide empirical confirmation of the theoretical expectations. It appears that intra-urban money wage differentials, differences in the quality of life, and variation in the cost of living in each city are jointly determined variables just as Rosen’s model of inter-city wage differentials predicts.

Wage‐setting Decisions on Newly Hired Employees: Survey Evidence from Colombian Firms

This paper uses a survey on wage formation applied to 1305 Colombian firms to study wage‐setting decisions of newly hired employees. The survey indicates that wages of the newly hired are based mainly on a predefined wage structure. This may help to explain, in part, the presence of downward nominal wage rigidities in the Colombian formal labour market, since firms are unwilling to differentiate the pay of new hires from the wages of existing workers. Using multinomial logit models, we find that firm size and the share of temporary workers increase the relative risk of using a predefined internal structure over bargaining between employee and employer when setting the wages of the newly hired employees.
