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).     

Picking “Lemons” or Picking “Cherries”? Domestic and Foreign Acquisitions in Norwegian Manufacturing*

We compare the performance in employment, wages and productivity for domestic plants acquired by new domestic and foreign owners. Prospective foreign owners pick large, high‐wage, high‐productivity plants, while new domestic owners choose average performers of above‐average size. Employment, labour productivity, and total factor productivity decline in domestic acquisition targets before acquisitions; only wages recover afterwards. Employment, wages and labour productivity increase after foreign acquisitions. The sample selection introduced by long‐term comparisons and a focus on unique events introduces a downward bias into the results for domestic acquisitions and an upward bias for the foreign acquisitions.     

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.     

Three million foreigners,three million unemployed? Immigration flows and the labour market in France

This paper investigates the effect of the flows of immigrant workers on the French labour market from the mid-1970s to the mid-1990s. Using a system of equations for unemployment, labour-force participation, the real wage and the immigration rate, it is shown that, in the long run, both legal and amnestied immigrant workers, and immigrant families lower the unemployment rate permanently. In the short-run, the arrival of immigrants increases unemployment slightly with an impact effect similar to that of an increase in domestic labour-force participation. The composition of immigration flows matters and the results indicate that the distribution between workers from the European Union and other regions of the world, also more skilled and less skilled workers, should remain balanced.     

Foreign ownership wage premia in emerging economies

In this article we examine the relationship between wages, labour productivity and ownership using a linked employer–employee dataset covering a large fraction of the Czech labour market in 2006. We distinguish between different origins of ownership and study wage and productivity differences. The raw wage differential between foreign and domestically‐owned firms is about 23 percent. The empirical analysis is carried out on both firm‐ and individual‐level data. A key finding is that industry, region and notably human capital explain only a small part of the foreign–domestic ownership wage differential. Both white and blue collar workers as well as skilled and unskilled employees obtain a foreign ownership wage premium. Foreign ownership premia are more prevalent in older and less technologically advanced firms. Joint estimation of productivity and wage equations show that, controlling for human capital, the difference in productivity is about twice as large as the wage differential. Overall, results indicate that the international firms share their rents with their employees.     

Unification and the policy predicament in Germany

We argue that wages have increased so far ahead of labour productivity in east Germany as to produce a problem that will continue to hound German policy-makers for the next two decades. Despite rapid rates of capital accumulation (around 9%) and growth (around 5%) in east Germany over the coming 10 years, our estimates show that even if wage catch-up decelerates greatly, as long as it continues, the rate of unemployment in the east will still be twice as high as in the west in another 10 years. Alternatively, if wage discipline forces the eastern unemployment rate to come down to the western level, wage differentials will widen substantially over these next 10 years. Thus serious problems loom ahead.     

Prices,Productivity and Wage Bargaining in Open Economies*

According to the standard union bargaining model, unemployment benefits should have big effects on wages, but product‐market prices and productivity should play no role in the wage bargain. We formulate an alternative strategic bargaining model, where labour and product‐market conditions together determine wages. A wage equation is derived and estimated on aggregate data for four Nordic countries. Wages are found to depend not only on unemployment and the replacement ratio, but also on productivity, international prices and exchange rates. There is evidence of considerable nominal wage rigidity. Exchange rate changes have large and persistent effects on competitiveness.     

PRODUCTIVITY GROWTH AND THE PHILLIPS CURVE: A REASSESSMENT OF THE US EXPERIENCE

In this paper, we analyse a new Phillips curve (NPC) model and demonstrate that (i) frictional growth, i.e., the interplay of wage staggering and money growth, generates a non‐vertical NPC in the long run and (ii) the Phillips curve (PC) shifts with productivity growth. On this basis we estimate a dynamic system of macro‐labour equations to evaluate the slope of the PC and explain the evolution of inflation and unemployment in the USA from 1970 to 2006. Because our empirical methodology relies heavily on impulse response functions, it represents a synthesis of the traditional structural modelling and (structural) vector autoregressions. We find that the PC is downward‐sloping with a slope of ?3.58 in the long run. Furthermore, during the stagflating 1970s, the productivity slowdown contributed substantially to the increases in both unemployment and inflation, whereas the monetary expansion was quite ineffective and led mainly to higher inflation. Finally, the monetary expansion and productivity speedup of the roaring 1990s were both responsible for the significant lowering of the unemployment rate.     

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.

Equilibrium unemployment with outsourcing and wage solidarity under labour market imperfections

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high- and low-skilled workers. When the labour union adopts a solidaristic wage policy, it will dampen this tendency. Further, higher outsourcing will increase equilibrium unemployment among the high-skilled workers, whereas it will reduce it among the low-skilled workers. Overall, outsourcing will reduce economy-wide equilibrium unemployment under the reasonable condition that the proportion of high-skilled workers is sufficiently low.     

Unemployment,long-term employment relations and the determination of unit labour cost growth in US manufacturing industries

This paper examines the effect that unemployment and long-term employment relations exert on the determination of unit labour costs. The paper proceeds in three sections. Section one analyses the relationship between labour market conditions and unit labour costs by developping a simple model of a firm that relies upon dismissal threats to elicit work effort. The comparative static properties of this model suggest that a tightening of labour markets may result in an increase in unit labour costs. In addition, it is argued that the labour market disequilibrium that occurs at full employment levels of unemployment will likely result in an increase in the growth rate of unit labour costs. The second section of the paper reviews diverse theories of long-term employment relations (LTERs), each of which suggest that the presence of LTERs ought to reduce the effect that labour market conditions exert on unit labour costs. The third section of the paper presents empirical estimates of the effect unemployment and LTERs exert on unit labour costs. The central empirical findings can be briefly summarized. First, movements towards full employment increase the growth rate of wages, reduce the growth rate of labour productivity and increase the growth rate of unit labour costs. Secondly, where long-term employment relations are prevalent, the effect of unemployment on wage, labour productivity, and unit labour cost growth is diminished. The paper concludes by discussing the implications these findings have for effort regulation models and the macroeconomic foundations of microeconomic labour market structures     

Unemployment and Growth in the Long Run: an Efficiency‐Wage Model With Optimal Savings*

An efficiency‐wage model of steady‐state equilibrium with labor‐augmenting technical progress is developed to explore the long‐run relationship between unemployment and growth. The rate of productivity growth is either specified exogenously or determined endogenously. In both cases, we preserve key results of the Shapiro–Stiglitz efficiency‐wage analysis without growth. Our model, however, also yields some striking new results. For instance, an exogenous increase in the growth rate may raise the rate of efficiency‐wage unemployment, and a once‐for‐all rise in the labor force may reduce the unemployment rate in the endogenous‐growth case.     

Transition Problems in Policy Reform: Agricultural Trade Liberalization in India

What will be the domestic growth and distributional effects of agricultural trade liberalization in India? How fast should Indian agriculture be liberalized and what policies should characterize the transition? This paper uses Indian agriculture to analyze medium‐term transition problems that arise in many major economic reforms. Employing a dynamic applied general‐equilibrium model, the paper focuses on the implications for policy design of the absence of efficient capital and labor markets and on the distributional consequences of economic reform in the presence of realistic limits on available intervention instruments. The key finding is that trade adjustment should be supplemented by policies that raise land productivity and, because this takes time, the adjustment should be gradual.     

Foreign capital inflow,skilled–unskilled wage inequality and unemployment of unskilled labour in a fair wage model

This paper has developed a three-sector general equilibrium framework that explains unemployment of both skilled and unskilled labour. Unemployment of unskilled labour is of the Harris–Todaro (1970) type while unemployment of skilled labour is caused due to the validity of the FWH in the high-skill sector. There are two types of capital one of which is specific to the primary export sector while the other moves freely among the different sectors. Inflows of foreign capital of either type unambiguously improve the economic conditions of the unskilled working class. However, the effects on the skilled–unskilled wage inequality and the extent of unemployment of both types of labour crucially hinge on the properties implied by the efficiency function of the skilled workers.     

UK wage underpayment: implications for the minimum wage

Dynamic monopsony suggests that, due to labour market frictions, workers will be paid below their productivity. This paper uses the stochastic frontier technique to estimate the degree of this underpayment for UK employees. It finds evidence of significant underpayment. The estimates are used to examine whether the predictions of dynamic monopsony are empirically accurate. No conclusive evidence against this theoretical framework is found. The paper also investigates whether payment according to productivity is a sufficient condition for the elimination of the ‘working poor’ problem. Due to the existence of an unemployment barrier, it finds that the minimum wage is not an effective anti-poverty policy.     

Do foreigners replace native immigrants? A panel cointegration analysis of internal migration in Italy

This paper examines the impact of the immigration of foreigners on domestic labor mobility. Since David Card's seminal study on the regional labor market impact of the Mariel Boatlift it is controversial whether domestic labor mobility equilibrates economic conditions across regions. However, there is little or no evidence that natives leave destinations where migrants tend to cluster. In this paper we reconcile the existing evidence by taking another route: we analyze whether the immigration of foreigners replaces domestic mobility from poor to rich regions. We focus on Italy, which is characterized by large North-South wage and unemployment differentials, and apply panel cointegration methods. The main finding is that, conditional on unemployment and wage differentials, the presence of foreign workers in the labor force of the destination regions discourages internal labor mobility significantly. As a consequence, spatial correlation studies which use the variance of the foreigner share across regions for identifying the wage and employment effects of immigration, tend to understate the actual impact of foreign immigration.     

HIGH-SKILLED MIGRATION AND THE EXERTION OF EFFORT BY THE LOCAL POPULATION

The optimal design of immigration policy is a topical issue, both in the policy debate and the economic literature. In this paper, we present empirical evidence from a firm level dataset collected in 2000 on the demand for high-skilled workers, including foreign workers, in Europe and its determinants. Our major findings are that the fraction of high-skilled workers recruited from the international labour market is very small, and that foreign and domestic workers are very similar in terms of their formal education (measured by specialization subject) and their job characteristics. We suggest an efficiency wage model to explain why firms recruit foreign workers in small numbers, and why they are willing to pay immigrants the same wage as local workers, whilst at the same time also paying for their moving costs, despite the similar human capital profile of immigrants to domestic workers.     

Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany,Greece, Ireland,Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.     

Social Status,Labour Market Frictions and Endogenous Growth

This paper develops an endogenous growth model that incorporates wealth‐enhanced preferences for social status and labour market frictions to investigate the role of social status in determining unemployment and long‐run growth. We show that the increase in the desire for social status reduces the unemployment rate, but its effect on long‐run growth is unclear. We then calibrate our model to the US economy and find that an increase in the desire for social status lowers the unemployment rate and enhances the economic growth rate in the long run.
