Full wages,part-time employment and the minimum wage

The economic effects of the minimum wage have become increasingly ambiguous. Historically, economists have asserted that increases in the minimum wage result in increases in unemployment. This relationship has been challenged recently by Card and Krueger, Katz and Krueger, and Card. These authors have provided empirical evidence that seems to indicate that there is no relationship between various economic variables (such as level of employment, and product price, among others) and the minimum wage. In addition, these authors have not provided a cogent presentation of the effects of the minimum wage on part-time employment. This study examines, from a theoretical standpoint, the effects of the minimum wage on employment. Furthermore, we emphasize the distinction between money wages and full wages; and the role that part-time employmentplays in the analysis. After incorporating these factors into a theoretical presentation, we provide empirical evidence by way of an OLS regression. We conclude that firms respond to increases in the minimum wage by altering the level of part-time employment. By doing this, firms are able to absorb the minimum wage increase because part timers receive fewer fringe benefits.     

Employment shifts, economic reform and the changes in public/private sector wages in Mexico: 1987–1997

Over the last decade, the public sector in Mexico experienced substantial fiscal reform, divestiture of public enterprises, and the elimination of many regulations affecting pay and employment. This study analyzes the changes in the public/private sector differences in wages during the 1987–1997 period. The results from analyzing microdata from the Encuesta Nacional de Empleo Urbano show that relative public sector wages increased from 1987 to 1997. Most of the relative wage increase in the public sector can be explained by increases in the price of skills and by changes in sorting across sectors. The results have important public policy implications since they suggest that public sector workers earn more and their wages have grown faster than those of their private sector counterparts. As such, policies contemplating public sector reform should take into account the effect of these measures on the inter-sectoral income distribution and the overall economic growth.

Minimum wages and the wage distribution in Estonia

Abstract: This article studies how changes in the statutory minimum wage have affected the wage distribution in Estonia, a post-transition country with little collective bargaining and relatively large wage inequality. The analyses show that the minimum wage has had substantial spillover effects on wages in the lower tail of the distribution; the effects are most pronounced up to the twentieth percentile and then decline markedly. The minimum wage has contributed to lower wage inequality and this has particularly benefitted low-wage segments of the labour market such as women and the elderly. Interestingly, the importance of the minimum wage for the wage distribution was smaller during the global financial crisis than before or after the crisis.     

The cyclicality of consumption,wages and employment of the public sector in the euro area

This study empirically examines the business cycle behaviour of public consumption and its main components, the public wage bill (including its breakdown into compensation per employee and public employment) and intermediate consumption, in the euro area aggregate, euro area countries and a group of selected non-euro area Organization for Economic Co-operation and Development (OECD) countries (Denmark, Sweden, the UK, Japan and the US). It looks across a large number of variables and methods, using annual data from 1960 to 2005. It finds robust evidence supporting that public consumption, wages and employment co-move with the business cycle in a pro-cyclical manner with 1–2 year lags, notably for the euro area aggregate and euro area countries. The findings reflect mainly the correlation between cyclical developments, but also point to an important role of pro-cyclical discretionary fiscal policies.     

Unions and wage inequality: The roles of gender,skill and public sector employment

We examine the changing relationship between unionization and wage inequality in Canada and the United States. Our study is motivated by profound recent changes in the composition of the unionized workforce. Historically, union jobs were concentrated among low-skilled men in private sector industries. With the steady decline in private sector unionization and rising influence in the public sector, half of unionized workers are now in the public sector. Accompanying these changes was a remarkable rise in the share of women among unionized workers. Currently, approximately half of unionized employees in North America are women. While early studies of unions and inequality focused on males, recent studies find that unions reduce wage inequality among men but not among women. In both countries, we find striking differences between the private and public sectors in the effects of unionization on wage inequality. At present, unions reduce economy-wide wage inequality by less than 10%. However, union impacts on wage inequality are much larger in the public sector. Once we disaggregate by sector, the effects of unions on male and female wage inequality no longer differ. The key differences in union impacts are between the public and private sectors—not between males and females.     

Evidence on the impact of minimum wage laws in an informal sector: Domestic workers in South Africa

What happens when a previously uncovered labor market is regulated? We exploit the introduction of a minimum wage in South Africa and variation in the intensity of this law to identify increases in wages for domestic workers and no statistically significant effects on employment on the intensive or extensive margins. These large, partial responses to the law are somewhat surprising, given the lack of monitoring and enforcement in this informal sector. We interpret these changes as evidence that strong external sanctions are not necessary for new labor legislation to have a significant impact on informal sectors of developing countries, at least in the short-run.     

A note on the shadow wage in LCDs with migration and formal and informal urban sectors

Given induced rural-to-urban migration, the social cost of (unskilled) labour for urban public sector projects is shown to be lower than the formal-sector, exogenously-determined wage. This result is valid not only when the urban alternative to formal employment is unemployment but also (and more realistically) when the relevant alternatives are formal employment, informal employment and unemployment.     

The impact of trade on the relative wages and employment of low skill workers in France

The impact of international trade on labour markets in developed countries will be different according to the degree of competition in product markets, the flexibility of the labour market and the skill intensity of production. An econometric analysis of the impact of trade in France has been undertaken using sectoral data for the period 1985–p1992. It is found that lower relative import prices reduce the relative employment of low skill workers in the first half the period and reduce their relative wages in the second half. In both cases the effect is more pronounced in sectors where the skill intensity of production is initially low.     

Economic reform,informal–formal sector linkages and intervention in the informal sector in developing countries: A paradox

Within a general equilibrium framework of a developing economy with a foreign owned factor of production, this paper questions whether the informal–formal sector relationship is pro-cyclical/complementary – expansion or contraction in one necessarily implies an expansion or contraction in the other – when the informal sector is subject to a technological shock. We derive a necessary and sufficient condition under which a positive shock to the informal sector results in an emphcontraction in both the size of the urban formal sector and the informal sector. Thus, although our result shows that the informal–formal sector relationship is pro-cyclical, it nevertheless calls into question the conventional wisdom on the benefits of intervention in the informal sector of developing economies, particularly where multinational corporations sub-contract certain labor-intensive stages of production to the informal sector.     

Wage inequality and between-firm wage dispersion in the 1990s: A comparison of rural and urban enterprises in China

Using a worker–firm matched sample, this paper compares the changes of wage structures of urban and rural enterprises following public sector restructuring in China's manufacturing sector. While the wage responses of rural firms with respect to firm characteristics are found to have declined steadily, compensation of urban workers has become increasingly linked to their firms' ability to pay. Our analysis reveals that industrial restructuring has weakened the influence of institutional factors, such as market power, soft budget constraints, and insider influence, on the wage determination of rural firms but it has enhanced their impact on urban firms.

The role of supervisors in the determination of wages and wage gaps

This article considers labour market discrimination by supervisors as a potential contributor to racial and gender wage gaps. Empirical analysis reveals evidence that all workers, except Hispanic males, earn significantly higher hourly wages when working for a supervisor of the same race and sex as themselves. Furthermore, the results suggest that sex has a larger impact on wages than race for workers with white supervisors, while race has a larger impact on wages than sex for workers with minority supervisors. Based on past research, we theorize that the degree of labour discrimination workers face may also be dependent upon the location and size of the firm in which they are employed. However, decomposing the samples by firm location and size suggests that these two factors cannot adequately explain the observed matched supervisor–worker wage effects, which supports the notion that these wage effects are largely driven by factors other than supervisor discrimination.     

Ageing, productivity and wages in Austria: sector level evidence

In this paper we analyse the link between the age structure of the labour force and average labour productivity as well as average wage across industrial sectors. While this intermediate economic level has been under-explored up to now, we will argue that it provides valuable insights in several respects. Our analysis is based on a panel data set ranging over 6 years (2002–2007). It covers the sectors of mining, manufacturing and market oriented services in the Austrian economy. Our results exhibit a positive correlation of the share of older employees and productivity, whereas we cannot find any evidence for a significant relationship of the share of younger employees and productivity. Moreover, the estimated age-wage pattern does not hint at an over-payment of older employees.     

Building the minimum wage: the distributional impact of Germany’s first sectoral minimum wage on wages and hours across different wage bargaining regimes

The first minimum wage in Germany was introduced in 1997 for blue-collar workers in sub-sectors of the construction industry. In the setting of a natural experiment, blue-collar workers in neighboring 4-digit industries and white-collar workers are used as control groups for differences-in-differences-in-differences estimation based on linked employer–employee data. Estimation results reveal a sizable positive impact on mean wages in East Germany, but no significant effect in West Germany. Size and significance of effects are neither homogeneous across wage regimes (individual vs. collective contracts) nor across the distribution. The patterns suggest a compression in the lower part of the wage distribution and spillover effects to wages where the minimum is not binding, even in West Germany, where the bite of the MW was low. No effects on hours of work or substitution between workers of different qualification levels are found.     

Spikes and spill-overs: The impact of the national minimum wage on the wage distribution in a low-wage sector

The UK National Minimum Wage (NMW) has had a minimal impact on UK wage inequality because it has been set at a modest level and because aggregate evidence suggests very small spill-over effects. But the small spill-over effects might be because of the small numbers of workers affected and widespread anticipation of the introduction of the NMW might make the impact effect appear very small. This paper investigates these issues using data collected from care homes where the NMW affected 40% of workers. But we still find no evidence of large spill-over effects and very small amounts of anticipation of the NMW.     

Insider-outsider forces in wage and employment determination: The case of Sweden

This paper applies a statistical approach used by Andersen & Hylleberg (1993) in their study of insider-outsider effects in wage-employment determination in the Danish manufacturing sector, to analyse insider-outsider effects in the Swedish private sector. Focusing on the univariate and multivariate trend properties of the data, a bivariate wage-employment error correction model is used as an explicit test-bed for the theoretical predictions of adjustments to anticipated and unanticipated shocks. According to the Blanchard & Summers (1986) insider-outsider model, the former changes are absorbed entirely by wages while the latter changes are reflected fully in employment. As in the case of analysis on Danish manufacturing data, it is found that the evidence based on data related to the Swedish private sector also fails to accept the Blanchard & Summers insider-outsider model in its unqualified version. Nonetheless several important traits of insider-outsider mechanisms seem to be in accordance with the observed evolution of the data.     

The minimum wage, employment, and the AS-IF methodology: A forecasting approach to evaluating the minimum wage

Out-of-sample employment forecasts for 33 U.S. industries which are likely to be sensitive to the federal minimum wage are, more often than not, more accurate when information about the minimum wage is not taken into account. This is true even in instances where this information improves wage forecasts. When employment forecasts conditional on the minimum wage are better, the improvement is typically small. These results are invariant to the number of workers previously making less than the new minimum wage, and to the value of the minimum wage relative to industry average wages.

Efficiency wages, employment, and the marginal income-tax rate: A note

In the framework of an efficiency-wage model, Hoel [Journal of Economics (1990) 51: 89–99] argues that a reduction in the marginal income-tax rate reduces employment. The present note shows that this result depends on how the tax reform is assumed to change the burden per worker. If the tax payment per worker is held constant, it cannot be ruled out that a lower marginal tax rate leads to an increase in employment.     

Minimum wage,on-the-job search and employment: On the sectoral and aggregate equilibrium effect of the mandatory minimum wage

We study the impact of a minimum wage in a segmented labor market in which workers are at different stages of their careers. At the end of a learning-by-doing period, workers paid the minimum wage quit “bad jobs” for better-paying “good jobs”, following an on-the-job search process with endogenous search intensity. A rise in the minimum wage reduces “bad jobs” creation and prompts workers to keep their “bad jobs” by reducing on-the-job search intensity. The ambiguous impact on unqualified employment replicates and explains the findings of several empirical studies. However, a minimum wage rise reduces overall employment and output.
