Involuntary unemployment,macroeconomic policy,and a behavioral model of the firm: Why high real wages need not cause high unemployment

The perspective of modern macroeconomic theory, be it new classical or old and new Keynesian, is that unemployment can be reduced only if real wages are cut. The modern Keynesians, basing themselves upon the microfoundations of efficiency wage theory, argue that real wages cannot and will not be cut by firms for efficiency wage reasons. This generates involuntary unemployment based on a market coordination problem. A behavioral model that contrasts with efficiency wage theory is presented here which suggests that reducing real wages need not affect the marginal cost of labor and, therefore, the number of individuals employed. In the behavioral model, wherein there exists some linearity in the relationship between real wages and working conditions and labor productivity, a lower real wage rate is not a necessary condition for reducing the unemployment rate nor is a higher real wage an obstacle to reducing it. In this scenario, unemployment, to the extent that it is demand-side induced, is not related to movements in real wages. Therefore, restoring full employment after a negative demand shock becomes a matter for demand management, not demand management that must be coordinated with measures designed to reduce real wages.     

REVISITING THE REAL WAGES–UNEMPLOYMENT RELATIONSHIP. NEW RESULTS FROM NON-LINEAR MODELS

We examine the long-run real wages–unemployment relationship for five OECD countries over the period 1960:1–2001:4. Given the theoretical possibility of non-linear equilibrium due to downward real wage rigidity we employ econometric tests that allow for the presence of non-linearities in the long-run equilibrium. We adopt the notion of 'hidden co-integration' suggested by Granger and Yoon . This methodology has several advantages with respect to other non-linear models. We find statistical evidence that, in general, there is a long-run positive relation between real wages and unemployment only when both are affected by positive shocks. We also find a negative relationship between unemployment and productivity. The empirical analysis is complemented with the estimation of error correction models for all countries.     

The market for labour in Israel

Using annual observations for 1960–89, a complete economic model of the Israel labour market is estimated in which the demand for labour varies inversely with real wages, participation varies directly with the real wages and real wages are explained by a phillips curve in which the natural rate of unemployment is a variable. The model suggests that while wages are far from flexible, unemployment shocks die away fairly rapidly. we were unable to model the behaviour of public sector pay and employment.     

Unemployment,wages and pensions

Empirical evidence has shown the existence of a negative relationship between the rates of unemployment and real wages. If pensions are computed according to the wages that workers have contributed, then the unemployment rates during working life may also influence the pensions to which they are entitled. Using data from 2005 to 2012 for the Spanish social security system, we estimate that the unemployment elasticity of real pension is ?0.135. A 1% increase in unemployment rate is associated with a reduction in pension equal to 0.135%. In ‘normal times’, this value could be considered modest, but the Great Recession has increased dramatically the rate of unemployment. In 2012, the rate of unemployment in Spain had increased to 25.7% and in 2015, it had diminished to 20.9%. It is estimated that unemployment rate will not be returned to figures existing before the crisis until middle of the next decade. Moreover, the current reforms in social security systems could interact with the future effects of the current rates of unemployment and cause future pensions to be significantly lower than those estimated by individuals. The economic welfare of the future cohorts of retirees would then be significantly worsened.     

The Macroeconomic Consequences of Long-Term Unemployment

This article examines the linkages between long-term unemployment and two important recent debates in Australia: first, whether unemployment exhibits hysteresis tendencies; second, the nature of the relationship between unemployment and real wages. Our findings favour the hysteresis account in that the evidence rejects an equilibrium relationship between long-term and total unemployment. Also, the effect on real wages of an increase in the number of longterm unemployed is found to be both positive and significant.     

The Beveridge curve and labour market dynamics in Turkey

This article investigates the dynamics of unemployment and vacancy rates in Turkey during the period 1951 to 2008 by means of a Beveridge Curve (BC). The time-series analysis of unemployment and vacancies as well as two other relevant labour market variables, real wages and real labour productivity, strongly suggests inefficiency in the Turkish labour market. A stable long-run relationship between unemployment rate and vacancy rate is found for Turkey, that is, the existence of a negatively sloped BC is verified. The estimated Turkish BC reflects the structural problems and lack of flexibility in the labour market. The modified BC with real wages and labour productivity reveals that labour productivity has no significant effect on unemployment rate whereas wages have positive and significant effects on the same variable.     

Real wage cyclicality in the Eurozone before and during the Great Recession: Evidence from micro data

We study the response of real wages to the business cycle in eight major Eurozone countries before and during the Great Recession. Average real wages are found to be acyclical, but this reflects, in large part, the effect of changes in the composition of the labour force related to unemployment variations over the cycle. Using longitudinal micro data from the ECHP and SILC panels to control for composition effects, we estimate the elasticities of real wage growth to unemployment increases between −0.6 and −1 over the period 1994–2011. Composition effects have been particularly large since 2008, and they explain most of the stagnation or increase in the average wage observed in some countries from 2008 to 2011. In contrast, at a constant labour force composition in terms of education and experience, the figures indicate a significant decrease in average wages during the downturn, particularly in countries most affected by the crisis. Overall, there is no evidence of downward nominal wage rigidity during the Great Recession in most countries in our sample.     

More on unemployment and vacancy fluctuations

Shimer [Shimer, R., 2005a. The cyclical behavior of equilibrium unemployment and vacancies. American Economic Review 95 (March), 25–49] argues that the textbook equilibrium search model of unemployment explains less than 10% of the volatility in US vacancies and unemployment when fluctuations are driven by productivity shocks. His paper as well as other recent work inspired by it are reviewed and extended here. Although there seems to be excessive feedback from the job-finding rate to the wage built into the Nash bargaining mechanism assumed to determine wages in the model, we argue that he and others overemphasize the need for wage rigidity to explain the data on labor-market fluctuations. Indeed, a modified version of the model can explain the magnitude of the empirical relationship between the vacancy–unemployment ratio and labor productivity when wages are the outcome of a strategic bargaining game and when the elasticity of the matching function and the opportunity cost of a match are set at reasonable values. The modified model also explains almost two thirds of the volatility in the ratio relative to that of productivity when separation shocks are taken into account, as well as the strong negative correlation between vacancies and unemployment found in Shimer's data.     

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.     

SHIRKING,STANDARDS AND THE PROBABILITY OF DETECTION

By relaxing the common efficiency wage assumption of exogenous shirking detection probabilities, we demonstrate how standards and efficiency wages are related. In a more general setting where the probability of detection depends upon the equilibrium effort level of non‐shirkers, we show that the uniformly positive (negative) supply‐side relationship between wages (unemployment insurance) and effort is no longer guaranteed. Profit maximization on the part of the firm, however, ensures that effort will depend positively (negatively) on wages (unemployment insurance) in equilibrium.     

Downward nominal wage rigidity in Canada: Evidence against a “greasing effect”

The existence of downward nominal wage rigidity (DNWR) has often been used to justify a positive inflation target. It is traditionally assumed that positive inflation could “grease the wheels” of the labour market by putting downward pressure on real wages, easing labour market adjustments during a recession. A rise in the inflation target would attenuate the long‐run level of unemployment and hasten economic recovery after an adverse shock. Following Daly and Hobijn (2014), we re‐examine these issues in a model that accounts for precautionary motives in wage‐setting behaviour. We confirm that DNWR generates a long‐run negative relationship between inflation and unemployment, in line with previous contributions to the literature. However, we also find that the increase in the number of people bound by DNWR following a negative demand shock rises with the inflation target, offsetting the beneficial effects a higher inflation target has on closing the unemployment gap. As an implication, contrary to previous contributions that neglected precautionary behaviour, the speed at which unemployment returns back to pre‐crisis levels during recessions is relatively unaffected by variations in the inflation target.     

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.     

Globalization and labor market outcomes: Wage bargaining, search frictions, and firm heterogeneity

We introduce search unemployment into Melitz's trade model. Firms' monopoly power on product markets leads to strategic wage bargaining. Solving for the symmetric equilibrium we show that the selection effect of trade influences labor market outcomes. Trade liberalization lowers unemployment and raises real wages as long as it improves average productivity. We show that this condition is likely to be met by a reduction in variable trade costs or by entry of new trading countries. Calibrating the model shows that the long-run impact of trade openness on the rate of unemployment is negative and quantitatively significant.     

Okun’s law revisited: a threshold in regression quantiles approach

This article proposes, for the first time, a threshold in regression quantiles approach to the analysis of Okun’s law. By applying to US data over the 1948Q1–2016Q4 period, we have three major findings. First, a single threshold is detected for both multiple and individual quantiles cases. However, the effect of threshold nonlinearity is only present in the middle to upper quantiles of the conditional unemployment distribution in the individual quantiles case. Second, the first-order autoregressive coefficients of unemployment are significantly larger in the lower-growth regime, indicating that shocks to unemployment appear to be more persistent during recessions. Finally, the Okun’s coefficients are all negative across the recessionary and expansionary regimes, confirming the validity of Okun’s law. Moreover, the Okun’s coefficients are smaller (more negative) in the lower-growth regime, suggesting that the effect of differenced output on differenced unemployment is asymmetric, and is more pronounced in recessions.     

The Welfare and Employment Effects of Centralized Public Sector Wage Bargaining

In many countries, the government pays almost identical nominal wages to workers living in regions with notable economic disparities. By developing a two‐region general equilibrium model with endogenous migration and search frictions in the labor market, I study the differences in terms of unemployment, real wages, and welfare between a regional wage bargaining process and a national one in the public sector. Adopting the latter makes residents in the poorer region better off and residents of the richer region worse off. Private sector employment decreases in the poorer region and it increases in the richer one. Under some conditions, the unemployment rate in the poorer region soars.     

Estimation of the specification error in the expectations theory of the term structure

This paper tackles the issue of the procyclicality of the real wage. We present a dynamic relationship between real wages and employment consistent with the long-run stationary equilibrium using a cointegrated VAR model. We find that wages are anticyclical and that a negative relationship between real wages and employment is necessary to achieve an economically identifiable stationary long run solution. The contentiousness of the topic does not appear so important once we recall some measurement issues and economic features of the Italian labour market.     

A dynamic spatial panel data approach to the German wage curve

A wage curve is a decreasing function of wages on the regional unemployment rate. Most empirical studies on the wage curve ignore possible spatial interaction effects between the regions which are the primary units of research. This paper reconsiders the western German wage curve with a special focus on the geography of labour markets. Spillovers between regions are taken into account. The paper tests whether the unemployment rate in the larger surrounding region also affects wages. In addition, agglomeration effects and effects of local monopsony are assessed.The main database is a random sample of 974,179 employees observed over the period 1980-2004 and covering 326 NUTS3 units (districts). This rich data set is used to estimate a dynamic wage curve according to the two-step approach of Bell et al. (2002). In the first step one controls for individual heterogeneity and in the second step one allows for spatial effects of unemployment across regions on wages. We check the sensitivity of this wage elasticity to various spatial weight matrices as well as allowing for the endogeneity of unemployment. We also estimate the wage elasticity for various population groups.     

The dynamics of regional unemployment in the UK, 1974–89

This paper investigates the relationship between regional and national unemployment for the UK for the period 1974–1989. This problem is approached by using the time-series methods of cointegration and causality tests. The main conclusions are that regional and national unemployment are not as closely related as might have been supposed although any causation may, as previously assumed, run from the national to the regional level. Some regions are seen to be changing their position in the hierarchy of relative regional unemployment while most retain their relative status.     

COLLECTIVE BARGAINING,AWARENESS OF GENERAL EQUILIBRIUM EFFECTS,AND UNEMPLOYMENT*

We explore the significance of general equilibrium feedback effects for wage‐bargaining. We examine a two‐sector economy and show that if agents only consider labor demand effects low real wages and low unemployment are the consequences. With an intermediate view, i.e., when partial equilibrium effects within a sector are taken into account, high real wages and unemployment result. If all general equilibrium effects are perceived simultaneously, we once again obtain a situation with low wages and unemployment. The results may explain why unemployment is high in some European countries.
