Minimum Wages for Ronald McDonald Monopsonies: a Theory of Monopsonistic Competition

Recent empirical work on the effects of minimum wages has called into question the conventional wisdom that minimum wages invariably reduce employment. We develop a model of monopsonistic competition with free entry to analyse the effects of minimum wages, and our predictions fit the empirical results closely. Under monopsonistic competition, we find that a rise in the minimum wage raises employment per firm, causes firm exit and may increase or reduce industry employment. Minimum wages increase welfare if they raise industry employment but welfare effects are ambiguous if employment falls.     

A model of wage and employment effects of service offshoring

This paper develops a two‐sector model of trade in goods and intermediate tasks that differ in tradability and skill intensity. A skill‐abundant country with high productivity is shown to offshore more unskilled tasks than skilled tasks, without relying on a particular correlation structure between tradability and skill intensity. With putty‐clay technology that allows retraining in the long run, transition from the non‐offshoring to the offshoring equilibrium generates wage and employment effects that switch from negative to positive as tradability declines, with the switches occurring at a higher degree of tradability for skilled tasks. This is consistent with the empirical literature.     

The Causal Effects of the Minimum Wage Introduction in Germany – An Overview

In 2015, Germany introduced a statutory hourly minimum wage that was not only universally binding but also set at a relatively high level. We discuss the short‐run effects of this new minimum wage on a wide set of socioeconomic outcomes, such as employment and working hours, earnings and wage inequality, dependent and self‐employment, as well as reservation wages and satisfaction. We also discuss difficulties in the implementation of the minimum wage and the measurement of its effects related to non‐compliance and suitability of data sources. Two years after the minimum wage introduction, the following conclusions can be drawn: while hourly wages increased for low‐wage earners, some small negative employment effects are also identifiable. The effects on aspired goals, such as poverty and inequality reduction, have not materialised in the short run. Instead, a tendency to reduce working hours is found, which alleviates the desired positive impact on monthly income. Additionally, the level of non‐compliance was substantial in the short run, thus drawing attention to problems when implementing such a wide reaching policy.     

THE MINIMUM WAGE, WAGE SUBSIDIES, AND POVERTY

In an attempt to augment the lowest wages, the United States and several other countries utilize legal minimum wages. However, the minimum wage has potentially adverse employment effects. The analysis here suggests that an alternative policy that combines a minimum wage and a wage subsidy is superior to either by itself. Such a combination can assist the low wage worker, avoid disemployment effects, and maximize market efficiency.     

Minimum wage impacts on youth employment transitions, 1993–1999

Abstract.  The longitudinal nature of the Master File of the Survey of Labour and Income Dynamics (SLID) for the period 1993–9, enables comparing transitions from employment to non‐employment for individuals affected by minimum wage changes with appropriate comparison groups not affected by minimum wages. This is based on the large number (24) of minimum wage changes that have occurred across the different provincial jurisdictions in Canada over the 1990s. The results indicate that the minimum wage increases have increased the transition from employment to non‐employment of employed low‐wage youths, who are at‐risk of being affected by a minimum wage increase, by around 6 percentage points (ranging from 4 to 8 percentage points). These disemployment effects in turn imply 'minimum wage' elasticities of about −0.4 (ranging from −0.3 to −0.5).     

Shocks and rigidities as determinants of CEE labour markets’ performance

In this article, the impact of real wage, productivity, labour demand and supply shocks on eight Central and Eastern European (CEE) economies from 1996–2007 is analysed with a panel structural vector error correction model. A set of long‐run restrictions derived from the dynamic stochastic general equilibrium (DSGE) model is used to identify structural shocks, and fluctuations in foreign demand are controlled for. We find that the propagation of shocks on CEE labour markets resembles that found for OECD countries. Labour demand shocks emerge as the main determinant of employment and unemployment variability in the short‐to‐medium run, but wage rigidities were equally important for observed labour market performance, especially in Poland, Czech Republic and Lithuania. We associate these rigidities with collective bargaining, minimum wage, active labour market policies and employment protection legislation.     

二元经济结构下最低工资的就业效应研究——基于劳动力市场的视角

现阶段我国整体就业形势不容乐观,分析最低工资对就业的影响具有重要的现实意义。通过对我国劳动力市场分割条件下最低工资的就业效应进行实证分析发现,最低工资对竞争性行业劳动力市场（城市二级劳动力市场）就业有显著的正面影响,对行政垄断行业劳动力市场（城市一级劳动力市场）就业的正面影响则很小。因此,根据我国劳动力市场的具体情况,合理设置最低工资标准有利于促进就业。     

The Effects of Germany's Statutory Minimum Wage on Employment and Welfare Dependency

In January 2015, Germany introduced a federal, statutory minimum wage of 8.50 € per hour. This study evaluates the effects of this policy on regular and marginal employment and on welfare dependency. Based on the county‐level administrative data, this study uses the difference‐in‐differences technique, exploiting regional variation in the bite of the minimum wage, i.e., the county‐specific share of employees paid less than 8.50 € before the introduction of the minimum wage. The minimum wage had a considerable negative effect on marginal employment. There is also some indication that regular employment was slightly reduced. Concerning welfare dependency, the minimum wage reduced the number of working welfare recipients, with some indication that about one half of them left welfare receipt due to the minimum wage.     

The Impact of Unionization Structures with Heterogeneous Firms and Rent‐Sharing Motives

How are unemployment and output affected if wages are set on the sector level rather than firm level? We take a new look at this question, allowing for heterogeneous firms and rent‐sharing motives. Without these motives, employment and output are lower under sector‐level wage‐setting due to higher wage markups. With rent‐sharing motives, however, firm selection is higher under sector‐level wage‐setting, which tends to increase employment and output, thus counteracting the markup effect. Simulations show that the firm‐selection effect decreases the difference between the two unionization structures substantially but it does not change the signs of the effects on output and employment.     

INTERNATIONAL WELFARE AND EMPLOYMENT LINKAGES ARISING FROM MINIMUM WAGES*

We formulate a two‐country model with monopolistic competition and heterogeneous firms to reconsider labor market linkages in open economies. Labor market imperfections arise by virtue of country‐specific real minimum wages. Abstracting from selection of just the best firms into export status, standard effects on marginal and average firm productivity are reversed in our model, yet there are significant gains from trade arising from employment expansion. In addition, we show that with firm heterogeneity an increase in one country’s minimum wage triggers firm exit in both countries and thus harms workers at home and abroad.

Minimum Wages and the Gender GAP in Pay: New Evidence from the United Kingdom and Ireland

Women are disproportionately in low‐paid work compared to men so, in the absence of rationing effects on their employment, they should benefit the most from minimum wage policies. This study examines the change in the gender wage gap around the introduction of minimum wages in Ireland and the United Kingdom (U.K.). Using survey data for the two countries, we develop a decomposition of the change in the gender differences in wage distributions around the date of introduction of minimum wages. We separate out “price” effects attributed to minimum wages from “employment composition” effects. A significant reduction of the gender gap at low wages is observed after the introduction of the minimum wage in Ireland, while there is hardly any change in the U.K. Counterfactual simulations show that the difference between countries may be attributed to gender differences in non‐compliance with the minimum wage legislation in the U.K.     

Entry Threats and Inefficiency in ‘Efficient Bargaining’

We study limit pricing in a model of entry with asymmetric information, where the incumbent firm's wage is endogenously determined through ‘efficient bargaining’ with its union. In the presence of entry threat, the incumbent firm‐union pair may face a conflict between rent sharing and transmitting its cost information. When the wage is not observable to outsiders and employment is the only signalling instrument, over‐employment features in all entry deterring contracts. When the wage is also observable, information transmission becomes easier. Most of the time, then, but not always, the efficient contract deters (induces) entry against the low (high) cost incumbent.     

LONGER‐RUN EFFECTS OF ANTI‐POVERTY POLICIES ON DISADVANTAGED NEIGHBORHOODS

We assess evidence on the longer‐run effects of minimum wages, the Earned Income Tax Credit, and welfare on key economic indicators of economic self‐sufficiency in disadvantaged neighborhoods. The evidence suggests that the longer‐run effects of the Earned Income Tax Credit are to increase employment and to reduce poverty and public assistance. We also find some evidence consistent with higher welfare benefits having longer‐run adverse effects, and stronger evidence that tighter welfare time limits reduce poverty and public assistance in the longer‐run. The evidence on the longer‐run effects of the minimum wage on poverty and public assistance is not robust. (JEL J22, J23, J38)     

Entry and Exit in International Markets: Evidence from Chilean Data*

Several studies examine the patterns and determinants of entry and exit in manufacturing industries. Not much work exists on entry and exit in international markets. This paper uses Chilean data to analyze the industry‐level determinants of entry and exit in export markets. First, we show as stylized facts that entry and exit rates differ across industries, vary over time, and are positively correlated. Then, we study the main determinants of these patterns. Our econometric analysis shows that within‐industry heterogeneity, measured by differences in productivity or other firm characteristics, has a significant effect on plant turnover in international markets. Our findings reveal that trade costs, factor intensities, and fluctuations in the real exchange rate play a minor role explaining entry and exit. This last result is consistent with hysteresis in international markets.     

An Efficiency Enhancing Minimum Wage

We consider an economy with a tax on all labor earnings. We discover that a slightly binding minimum wage on one sector can enhance efficiency. The minimum wage attracts high‐reservation wage workers into the minimum‐wage sector. If the labor demand curve in the free sector is quite flat, the vast majority of workers displaced by the minimum wage find employment in the free sector, raising aggregate employment. This displacement of workers by the only slightly binding minimum wage has negligible effects on efficiency. So efficiency and tax revenue rise as the minimum wage pulls labor out of untaxed leisure, where too much of the labor force is lurking, into taxed work.     

Long‐Term Impact of Minimum Wages on Workers’ Careers: Evidence from Two Decades of Longitudinal Linked Employer–Employee Data

We analyze the impact of high youth minimum wages, relying on two decades of linked employer–employee data and a major law change. Alternative treatment/control groups follow from two strands of the literature, one tracking low‐skilled workers employed before the law change, who are eligible for a large wage increase, and one tracking the employment of full cohorts, whether working or in school when the law changed. High minimum wages led to a short‐term wage gain, which faded over time. They did not jeopardize employment prospects. Changes in the hours worked by part‐time workers point to increased job attachment.     

Its Bark is Worse Than its Bite: The Wage and Employment Effects of the Minimum Wage in the US

This study examines the effect of changes in the US minimum wage on wages and employment in 32 industries selected for their presumed sensitivity to the minimum wage. Applying time series techniques commonly used in macroeconomics and finance to changes in the minimum wage occurring from 1967 and 1991, we initially test for a wage response; only where one is found do we test for an employment response. Twenty-five per cent of the industry/minimum-wage-increase pairs show evidence of an appropriate wage response. Eight of these 54 show a statistically significant negative employment response, while six show significant, positive employment responses. Positive effects may be due to either a high variance distribution centred on zero or markets with 'lemons' problems concerning worker quality. Limiting analysis to industries in which the minimum wage binds provides no evidence of a consistent negative relationship between the historical minimum wage and employment.     

试论加入WTO对中国就业结构的影响

在分析就业弹性变化的基础上，本文考察了入世对就业的影响，总体上来看，WTO对就业的影响在方向上和目前就业的发展和变化趋势一致，这就决定了入世对就业不会造成净负面影响，但分三次产业来看，入世对就业的影响是不同的，农业是受入世影响和冲击最严重的行业，但农业因此而损失的就业机会中相当于目前农村剩余劳动力数量的极小一部分，约占0.7-1%左右，入世对农业的影响和冲击主要体现在收入而不是就业上；入世对工业就业的影响有正有负，这要依具体工业待业特点而定，但增减相抵，入世对工业就业仍然具有增加效应；最后，入世将大大促进就业机会的增加，第三产业就业是中国入世最大的收益者。
