Unemployment and product market competition in a Cournot model with efficiency wages

This paper analyzes the impact of product market competition on unemployment, wage and welfare in a model where unemployment is caused by the efficiency wage consideration and oligopolistic firms compete in quantity. It is shown that while more intense competition in the product market increases output and reduces price, it does not necessarily lead to a lower unemployment rate or a higher wage for workers. Depending on the technologies, the relationship between the intensity of competition and the level of employment (respectively, wage, welfare) is not always monotonic, and, in some instances, has an inverted U‐shape.     

Factor‐biased public infrastructure and wage inequality

This paper analyzes how factor‐biased public infrastructure affects the skilled–unskilled wage inequality. In the basic model with a full employment economy, we find that when the weighted dependence of skilled labor and capital in the urban skilled sector on public infrastructure is large enough relatively to that of unskilled labor and capital in the urban unskilled sector, the wage inequality will be expanded. We also discuss labor‐biased and capital‐biased public infrastructure in our framework, and find that the relative dependences of relevant labor or capital on public infrastructure are important determinants of wage inequality. In the extended models, we analyze separately the issue of wage inequality in the economy with unemployment and the totally open capital market, and find the results of the basic model almost still hold.     

Political‐Economic Regime and the Wage Curve: Evidence from Chile, 1957–96

This paper tests whether a wage curve—a negative relationship between the level of unemployment and the level of pay—existed in Chile during 1957–96. The analysis is divided into two periods. For 1957–73, during inward‐led development, we reject the existence of a wage curve. For 1974–96, when the economy opened, state‐run industries were privatised and labour rights weakened, we find a wage curve of ?0.08. Based on this finding we conclude that the unemployment–pay elasticity in the post‐reform period is similar to the ?0.07 to ?0.10 wage curve found in other western, capitalist countries. Disaggregating the analysis by group, we find that women, non‐university educated workers and public sector workers have suffered more from unemployment. Yet informal sector workers have not experienced pay drops as a result of unemployment, contradicting the hypothesis that the informal sector acts as a buffer during economic downturns.     

The NAIRU reconsidered: why labour market deregulation may raise unemployment

According to the mainstream theory of equilibrium unemployment, persistent unemployment is caused mainly by ‘excessive’ labour market regulation, whereas aggregate demand, capital accumulation and technological progress have no lasting effect on unemployment. We show that the mainstream non‐accelerating inflation rate of unemployment (NAIRU) model is a special case of a general model of equilibrium unemployment, in which aggregate demand, investment and endogenous technological progress do have long‐term effects. It follows that labour market deregulation does not necessarily reduce steady‐inflation unemployment. Theoretically, if the decline in real wage growth claims owing to deregulation is smaller than the ensuing decline in labour productivity growth and in the warranted real wage growth, then in that case steady‐inflation unemployment may increase. Empirical evidence for 20 Organisation for Economic Cooperation and Development (OECD) countries (1984–1997) indicates that the impact of labour market deregulation on OECD unemployment is zero, and possibly negative (causing a higher rate of unemployment).     

Anti‐immigration policy in the destination country and skilled–unskilled wage inequality in a source economy with or without unemployment

This paper is aimed at theoretically examining the consequence of the anti‐immigration policy adopted in the destination country on the skilled–unskilled wage inequality in a source nation using a couple of two‐sector, specific‐factor general equilibrium models in both the presence and absence of unemployment. Emigration requires incurring some capital cost for professional skill formation on the part of every prospective emigrant that adds to the opportunity cost of emigration. The authority of the destination country determines the number of visas to be granted and hence directly controls the magnitude of skilled emigration from the source country. In the migration equilibrium, the expected skilled wage income abroad is equal to the opportunity cost of emigration. In both the presence and absence of unemployment of unskilled labor, the outcome of the policy on the wage inequality crucially hinges on both the magnitude of the fixed cost of emigration and the technological factors. In the specific‐factor Harris–Todaro model, the degree of imperfection in the unskilled labor market is an additional factor. Finally, some policy recommendations have been made for protecting the interest of the poor unskilled workforce.     

Exploring different measures of wage flexibility in a developing economy context: the case for Turkey

In this paper we use Turkish household labor force data to address a number of conceptual issues pertaining to the wage curve, an empirically derived negative relationship between the real wage level and the local unemployment rate. First, we show that in developing economies where labor markets are prone to high degree of segmentation by skill level, local unemployment rates disaggregated by education provide more accurate measures of the degree of group-specific wage competition and hence yield more robust results of the wage curve analyses. Second, we estimate the wage curve using various definitions of the unemployment rate, including discouraged and marginally attached workers, and the long-term unemployment rate to explore the most relevant measure of local labor market tension in the wage setting process. We find that broader definitions of unemployment serve as a more effective reference point in measuring wage flexibility for women, whose attachment to the labor market is substantially weak in the Turkish context; while for men the official and long-term unemployment rates perform well. Finally, using quantile regression we show that wage responsiveness to unemployment cannot be assumed to be constant along the wage distribution. In the Turkish case, we find a higher unemployment elasticity of wages around the median segment of wage distribution. This effect is more pronounced for women.     

Skilled-unskilled wage inequality and unemployment: A general equilibrium analysis

The paper develops a static three sector competitive general equilibrium model of a small open economy in which skilled labor is mobile between a traded good sector and the non-traded good sector and unskilled labor is specific to another traded good sector. Capital is perfectly mobile among all these three sectors. We introduce involuntary unemployment equilibrium in both the labor markets and explain unemployment using efficiency wage hypothesis. We examine the effects of change in different factor endowments and prices of traded goods on the unemployment rates and on the skilled-unskilled relative wage. Also, we introduce Gini-Coefficient of wage income distribution as a measure of wage income inequality; and show that a comparative static effect may force the skilled-unskilled relative wage and the Gini-Coefficient of wage income distribution to move in opposite directions in the presence of unemployment.     

Wage bargaining,trade and growth

We construct a North-South product-cycle model of trade with fully-endogenous growth and union wage bargaining. Economic growth is driven by Northern entrepreneurs who conduct R&D to innovate higher quality products. Northern production technologies can leak to the South upon successful imitation. The North has two sectors: a tradable industrial goods sector (manufacturing) where wages are determined via a bargaining process and a non-tradable sector (services) where wages are flexible. The South has only a tradable industrial goods sector where wages are flexible.We find that unilateral Northern trade liberalization, in the form of lower Northern tariffs on industrial goods, increases the rate of innovation but decreases both the bargained wage in the industrial sector and the flexible wage in the service sector. The wage effects are relative to the Southern wage rate. We also consider a variant of the model with Northern unemployment, driven by a binding minimum wage in the non-tradable service sector. In this case, Northern tariff cuts decrease the innovation rate and the bargained wage rate. In addition, the Northern unemployment rate increases. The model thus highlights the role of labor market institutions in determining the growth and labor market effects of tariff reductions. We also study the effects of unilateral Southern trade liberalization.     

Labor Market Segmentation and the Implications for Public Sector Retrenchment Programs

Despite the importance placed on reducing public sector employment in sub-Saharan Africa, remarkably little is known about the labor market transition paths of departing public sector workers. This paper uses household survey data from Conakry, Guinea to establish evidence of labor market segmentation between the wage and nonwage sectors. An empirical model of the unemployment durations experienced by departing public sector workers finds that transition paths vary significantly according to personal characteristics that also affect the resulting earnings opportunities in segmented labor markets. Particularly, there is a marked tendency of females to enter quickly the nonwage sector, relative to males, and a negative influence of severance payments on wage sector employment acceptance.J.

Real Minimum Wage and Growth Theory: Simulations and Some Policy Results

Abstract

A Solow type two‐sector growth model is used to examine several issues related to growth and unemployment in a minimum wage economy. By simulating the model, we demonstrate that given the same percentage increase in wage rate, an economy with a higher capital–labor ratio is more likely to decay. More importantly, a tariff policy reduces the unemployment periods by 92% provided that the current capital–labor ratio is one‐sixth of that of the steady state capital–labor ratio. We assume that the first best policy of uniform wage subsidy is not politically feasible.     

Wage indexation,migration, and unemployment

This article sets up a two-goods model with wage indexation and migrants. A dual labor market is introduced where the domestic workers receive an indexed wage while migrants receive a market-determined wage. The traded sector may be assumed to be unionized while the non-traded goods sector is non-unionized giving rise to flexible wages. This provides an example of segmentation and wage indexation. The wage indexation creates unemployment in the traded sector and the segmentation allows this unemployment to persist. The main results obtained are: sector-specific migration of labor may raise domestic welfare, while with capital accumulation such migration necessarily raises the relative price of the non-traded goods, leading to structural adjustment.     

Urban unemployment, informal sector and development policies

We analyze the effects of wage subsidy policies on unemployment and welfare in the model that is characterized by the existence of both open unemployment and the informal sector that producesfinal goods. Our main findings are as follows. Wage subsidies to the agricultural and informal sectors increase welfare and decrease urban unemployment. The effects of a wage subsidy to manufacturing sector on welfare and unemployment are conditional. We identify some sufficient conditions for the definite results and interpret them.     

Corporate profit tax,firm entry with unemployment,and income inequality

In this paper, we provide a general equilibrium analysis of corporate profit tax on income distribution, unemployment, and wage inequality. With firm dynamics in industrial sector, we identify a new channel through which profit tax affects income and wage inequality: profit tax cut will widen not only the wage gap between skilled and unskilled labor, but also exacerbate the wage inequality of unskilled labor among different sectors. The welfare effect of profit tax cut depends on unemployment deepening (labor-distortion effect) and more manufacturing firms enter the market (business-creation effect), eroding the market share of incumbent firms (business-stealing effect).     

UNEMPLOYMENT POLICIES IN AN ECONOMY WITH ADVERSE SELECTION

This paper studies the effects of unemployment policies in a simple static general equilibrium model with adverse selection in the labour market. Firms offer a contract that induces the self‐selection of workers. In equilibrium, all unskilled workers are screened out and some skilled workers are rationed out. It is shown that the provision of unemployment insurance raises involuntary unemployment by encouraging adverse selection, while unemployment assistance – or subsidy to unemployment – reduces involuntary unemployment. A simple efficiency wage model is also presented to show that either of the two policies reduces employment by taxing effort and subsidizing shirking. The key is whether the social role of unemployment is a sorting device or a worker discipline device.     

HETEROGENEITY AND THE PUBLIC SECTOR WAGE POLICY

A model with search and matching frictions and heterogeneous workers was established to evaluate a reform of the public sector wage policy in steady state. The model was calibrated to the U.K. economy based on Labour Force Survey data. A review of the pay received by all public sector workers to align the distribution of wages with the private sector reduces steady‐state unemployment by 1.4 percentage points.     

FiMod — A DSGE model for fiscal policy simulations

This paper develops a medium-scale dynamic, stochastic, general equilibrium (DSGE) model for fiscal policy simulations. Relative to existing models of this type, our model incorporates two important features. First, we consider a two-country monetary union structure, which makes it well suited to simulate fiscal measures by relatively large countries in a currency area. Second, we provide a notable degree of disaggregation on the government expenditures side, by explicitly distinguishing between (productivity-enhancing) public investment, public purchases and the public sector wage bill. In addition, we consider a labor market characterized by search and matching frictions, which allows to analyze the response of equilibrium unemployment to fiscal measures. In order to illustrate some of its applications, and motivated by recent policy debate in the Euro Area, we calibrate the model to Spain and the rest of the area and simulate a number of fiscal consolidation scenarios. We find that, in terms of output and employment losses, fiscal consolidation is the least damaging when achieved by reducing the public sector wage bill, whereas it is most damaging when carried out by cutting public investment.     

The role of unemployment in wage determination: further evidence on the wage curve from Turkey

This paper presents an empirical estimation of the correlation between wages and regional unemployment rates in Turkey, more specifically it explores the role of regional unemployment rates in wage determination. The analysis builds upon a series of recent empirical studies on the wage-unemployment relationship, now commonly known as ‘the wage curve’, a downward sloping curve in wage-unemployment space. The existing studies are for most part in advanced market economies, while this paper presents one of the few attempts at a wage curve analysis within the context of a developing market economy. A cross-sectional estimation of micro level individual wage data for the Turkish labour market in 1994, suggest a statistically significant negative correlation between wages and regional unemployment rates. Separate regressions for men and women, however, show a wage curve to exist only in the male labour market. The study also presents the results on other variables of wage determination such as returns to schooling, returns to age, job tenure, gender, industrial and occupational affiliation of the worker, economic sector and union status.     

Optimal Redistributive Income Taxation and Efficiency Wages*

In this paper, we integrate efficiency wage setting with the theory of optimal redistributive income taxation. In doing so, we use a model with two skill types, where efficiency wage setting characterizes the labor market faced by the low‐skilled, whereas the high‐skilled face a conventional, competitive labor market. We show that the marginal income tax implemented for the high‐skilled is negative under plausible assumptions. The marginal income tax facing the low‐skilled can be either positive or negative, in general. An increase in unemployment benefits contributes to a relaxation of the binding self‐selection constraint, which makes this instrument particularly useful from the perspective of redistribution.     

Small Firms and Unemployment in a Two-sector Model

This paper presents a two-sector model of an economy – one sector consisting of large firms with institutionally determined wage (the Formal sector) and the other sector consisting of small firms (the Informal sector). The paper examines the effects of changes in benefits, entrepreneurial zeal, and the institutionally determined wage in the Formal sector on unemployment. It concludes with brief comments on the role of aggregate demand and supply policies in reducing unemployment in this economy.     

Public Consumption and Unemployment

This paper introduces public consumption—hence the size of the public sector—into an efficiency wage model of the labour market. The effect of a simultaneous rise in taxes and public consumption on unemployment is derived. There arises an unambiguous positive relationship between the size of the public sector and equilibrium unemployment if public and private consumption are substitutes and wages are taxed. The impact of taxes on consumption on unemployment, although in general not equal to zero, is ambiguous.
