Efficiency wages,unemployment and international factor movements

This paper examines the implications of unemployment resulting from efficiency wages for international factor movements in a standard Heckscher-Ohlin model where the relative size of the endowments of skilled and unskilled workers and the efficiency wage induced unemployment level in the unskilled labour market are simultaneously determined given the population, supply of capital and its distribution in the economy. Capital in the economy is used only to train individuals for the skilled labour market, where workers are fully employed. It is shown that the optimum labour inflow in the market with domestic distortion and the optimum capital inflow are always positive because they reduce the severity of distortion by raising employment and income for the residents. The income and employment of foreigners also increase. Under this situation the optimum labour or capital outflow on the other hand is always zero. These conclusions directly contradict the result obtained for international factor movements in the presence of exogenously determined unemployment.

Contracts,the Spot Market Wage and Unemployment Benefits

This paper presents a model of the labour market with a contract and a spot market sector. Contracts are binding and enforceable, but unemployed contract workers are free to work in the spot market. The contracting wage is shown to be constant across states. A non‐trivial result shows that the spot market wage is increasing with product price. An increase in product price has an ambiguous effect on contract employment. An increase in unemployment benefits increases the contracting sector wage whilst stabilizing the spot market wage, and may have ambiguous effects on unemployment.     

Structural Reforms and Labour‐market Outcomes: International Panel‐data Evidence

This paper explores the impact of structural reforms on a comprehensive set of macro‐level labour‐market outcomes, including the unemployment rate, the average wage index, and overall and female employment levels and labour force participation rates. Together, these outcome variables capture the overall health of the labour market and the aggregate welfare of workers. Yet, to our knowledge, there seems to be no other comprehensive empirical investigation in the existing literature of the impact of structural reforms at the cross‐country macro‐level on labour‐market outcomes other than the unemployment rate. After documenting the average trends across countries in the labour‐market outcomes up to 10 years on either side of each country's structural reform year, we run fixed‐effects ordinary least squares and instrumental variables regressions to account for the likely endogeneity of structural reforms to labour‐market outcomes. Overall, the results suggest that structural reforms lead to positive outcomes for labour. Redistributive effects in favour of workers, along the lines of the Stolper‐Samuelson effect, may be at work.     

Vor der Bundestagswahl: Argumente für Mindestlöhne überzeugen nicht

For the first time ever, all political parties represented in the German Bundestag are proposing some form of minimum wage regulation in their federal campaigns. After sketching an overview of the vast empirical literature on the employment effects of minimum wages, which has yet to come to a consensus, the paper concentrates on the most common theoretical arguments for the view that minimum wages need not reduce the employment levels of affected workers. The authors find that those arguments are either conceptually inconsistent or assume market characteristics that can hardly describe the reality of low-wage labour markets. In the end, minimum wages are a blunt instrument to reduce poverty among workers — its primary objective — because it benefits many that are not poor and does not address the most important determinant of poverty in Germany, namely unemployment.     

LABOUR SUBSIDIES: A NEW LOOK

This paper reexamines the case for subsidizing employment. One superficially promising approach, based on the idea that government cofinancing of unemployment benefits could induce firms to lay off too many workers in bad times, turns out to be an unsatisfactory argument for employment subsidies when worker-firm contracts are optimal. But efficiency wage explanations for unemployment offer considerable scope for a revenue-neutral combination of a specific labour subsidy and ad valorem wage tax. When pitched low enough, unemployment must fall under a wide set of conditions.     

Trade,Technical Change,and Labour Market Adjustment

This paper empirically examines three possible reasons for the high and rising unemployment of low‐skilled employees in Germany: (i) an upsurge in inter‐industry trade, (ii) a skill‐biased technical change, and (iii) a failure of labour market adjustment. The empirical analyses indicate that an exogenous wage‐setting process as well as a bundle of factors, including a skill‐biased technical and structural change, have contributed to the decline in relative demand for low‐skilled employees in Germany. Thus, economic policy in Germany should focus on improving the employability of workers in the lower segment of the labour market and on raising the adjustment flexibility, above all the flexibility of the wage structure, of the German labour market.     

MONOPOLISTIC COMPETITION AND SEARCH UNEMPLOYMENT

In this paper the monopolistic competition model of Dixit and Stiglitz for the goods market and the search unemployment model of Pissarides are combined. The Pissarides part loses its Walrasian goods market and the Dixit–Stiglitz part loses its Walrasian labour market. Pissarides’ results now depend on the degree of competition. In the Dixit–Stiglitz part the size and number of firms as well as aggregate output now depend on aggregate hiring costs, tightness and unemployment, while real wages are not fixed. Some partial results of comparative static properties of the original models survive. New results concerning the effects of changes in labour (goods) market parameters on goods markets (the labour market) variables are obtained and related to the literature on macroeconomic theory with endogenous unemployment and imperfect competition, empirical results and policy issues.     

Labour market institutions,learning and self-employment

We develop a dynamic partial-equilibrium model to analyse how labour market institutions (wage compression, minimum wages, unemployment benefits, mobility costs and fixed-costs of self-employment) and learning affect who and when people become self-employed. We find that certain ability groups of workers become self-employed for both “carrot” and “stick” reasons: Some prefer self-employment to the low institutionalised wage, while others are not productive enough to qualify for a job at the institutionalised wage. Furthermore, wage compression and learning may give rise to a class of switchers who start in wage employment and later switch to self-employment. Several predictions of the model are consistent with observed empirical regularities, such as the existence of a group of low-skilled self-employed workers, the increasing propensity for self-employment over age groups and the larger spread in earnings among self-employed.     

论如何同时降低通货膨胀率和失业率——菲利普斯曲线的微观经济基础及其移动

菲利普斯曲线有其微观经济基础。菲利普斯曲线描述的货币工资变化率与失业率之间的关系取决于失业工人随机寻找工作的经济决策、在岗工人与公司之间的博弈行为、工会势力与公司讨价还价力量的均衡、公司调整产品价格和工人工资的决定、劳动供给曲线的斜率等。以此为理论基础,通过对工作报价、最低工资预期水平、搜寻工作的效率、工会势力和公司势力、辞职率与临时解雇率、生产技术效率、劳动周转率、劳动市场分隔及其不平衡等因素进行政策性调节,可以使菲利普斯曲线整体性向左下方移动,从而同时降低通货膨胀率与失业率。     

Ökonomische Wurzeln des Populismus

Increasing populism in developed Western countries such as Germany can be traced to various causes, including economic ones. In these countries, advancing globalisation and technological progress lead to labour market and income effects that have had a negative impact on certain groups of people (wage reduction, increase in the risk of unemployment). The fear of such developments — whether justified or unfounded — results in the desire for political decisions that push back the catalysts of these economic developments. Therefore, international trade with low-wage countries and labour saving technological progress in particular often breed populist parties.     

IS LABOUR MARKET FLEXIBILITY DESIRABLE OR HARMFUL? A FURTHER DYNAMIC PERSPECTIVE

A common belief of mainstream economics as well as underpinning government policy is that the more flexible real wage is, the lower is unemployment. In this paper we study the dynamics of a standard neoclassical labour market under the simplest Walrasian adjustment rule. We show that when consumption and leisure are sufficiently low substitutes, an increase in real wage flexibility may destabilize the unique Walrasian equilibrium of the economy, triggering fluctuations in wages and employment. Minimal departures from strict (Walrasian) neoclassical equilibrium modelling are required to obtain instability results for wage flexibility.     

Shadow price of working in the shadows: services industry evidence

ABSTRACT

In this paper, we use an exogenous policy variation in the labour market to determine the wage gap between formally and informally employed workers. For our purposes, ‘informal employment’ describes employees who are not officially registered with any social security scheme. We use self-reported employee registration status to identify such workers, but the choice of working unregistered is not exogenous. Nevertheless, through an amnesty that was extended to only some workers in the labour market, we reduce the endogeneity problem, enabling estimation of the wage gap between these two groups. Our two-stage least square estimates reveal that the hourly wage penalty of working in the shadows is as high as 59%, and the monthly salary penalty is around 66%. Moreover, the wage gap is higher (as high as 70%) for those working in the services sector, as unregistered workers in this sector tend to be low skilled and low educated, and the monitoring of this sector is more difficult. Our analysis contributes to the literature by using an instrumental variable to treat the endogeneity of workers’ registration status. In addition, it shows that people working informally in the services industry receive a higher average wage penalty than other informally employed workers.     

Lessons Learnt from the Nordics: How to Fight Long-term Unemployment

This study examines policies that can successfully address long-term unemployment. It focuses on Denmark and Sweden, where, despite sizeable job losses during the crisis, labour market indicators are at present better than in any other EU country. By looking at the interaction between labour market flexibility (especially in hiring and firing regulations) and passive and active policies, we argue that well-designed active policies matter more than labour market flexibility for employment.     

A SCHUMPETERIAN GROWTH MODEL WITH EQUILIBRIUM UNEMPLOYMENT

We introduce efficiency‐wage unemployment in a model of growth with endogenous technical change. Our research aim is twofold. First, we try to provide an analytically tractable model of growth with efficiency‐wage unemployment that can be viewed as alternative to the standard models of growth and search unemployment. Second, we try to analyze the steady‐state effects of some labor market policies on unemployment and growth. We find that a positive relationship between growth and unemployment exists and that the effectiveness of any labor market policy aimed at improving the performance of the labor market crucially depends on how individuals discount future income.     

TESTING WAGE AND PRICE PHILLIPS CURVES FOR THE UNITED STATES

This paper demonstrates how the labour and product markets interact in determining as outcome a generalized reduced‐form price Phillips curve. For the labour market we consider a wage Phillips curve and for the product market a price Phillips curve. We estimate separately the wage and price Phillips curves for the USA, using ordinary least squares, non‐parametric estimation and three‐stage least squares techniques. The finding is that wages are always more flexible than prices with respect to their respective demand pressure and that price inflation responds somewhat more to a medium‐run cost pressure than does wage inflation. The implications for macroeconomic stability are demonstrated. We also show—as a link between product and labour markets—that employment is related to output as Okun's law states. In comparing linear and non‐linear estimates of the wage and price Phillips curves we find furthermore that for some relationships non‐linearities are important while not for others. Although overall the non‐linear estimates tend to confirm our linear estimates, non‐linearities in some relationships of the Phillips curve are important as well.     

Sectoral shifts Impact on Hong Kong workers

This paper documents the accelerating rate of economic transformation in Hong Kong during the 1980s and its impact on the labour market. Earnings in expanding sectors have risen faster than earnings in declining sectors. The magnitude of the effect, however, is small and variable. Sectoral shifts have also had negligible effects on aggregate unemployment and unemployment in declining sectors. It is found that the degree of earnings inequality has increased contemporaneously with the rising rate of economic transformation. The earnings of less well-educated workers have fallen relative to other workers. The earnings of elderly workers, however, have not fallen relative to other workers. The reallocation of labour from low-wage sectors to high-wage sectors has resulted in a substantial growth in earnings for most workers involved.     

EMU and Labour Market Reform: Needs,Incentives and Realisations

Despite improving labour market conditions in recent years, a number of EMU countries still suffer from high and persistent unemployment. It could therefore be expected that labour market reform would be given a prominent position on the political agenda. The new constraints associated with the common monetary policy only increase the pressure for reform. Relying on the introduction of the single currency as a trigger for labour market reform may be a risky strategy. EMU generates a complex set of re‐optimising strategies of the players on the labour market, which makes it difficult to get a clear idea what impact it will have on labour market reform. Evaluation of recent reform measures does not make one confident either. The empirical analysis confirms to some extent the idea that countries with higher unemployment rates have carried out more labour market reform. This finding holds, however, only for countries that do not belong to EMU. EMU countries have on average carried out no more reform than countries outside EMU and any link between the initial unemployment level and the labour market reform indicators seems to lack. It may become apparent that more reform is needed once the macroeconomic environment becomes more unfavourable.     

Compensating Differentials for Dangerous Work in a Labour Discipline Model

Wage compensation for occupational risk in Walrasian models has three properties: it generates efficient levels and allocations of risk, it enables workers in dangerous jobs to be just as well off, ceteris paribus, as workers in safe jobs, and it permits the estimation of willingness to pay schedules for safety from labour market data. This paper tests the status of these three properties under a simple model in which variable labour effort is induced by wage–safety rents and the threat of dismissal. It finds that all three must be modified, and that these results are robust over alternative specifications of labour market structure, the cost of providing safety, and the specification of the production function. The implications of this analysis are considered for both public policy questions and the interpretation of wage–risk studies.     

US immigration policies and dynamics of cross‐border workforce in agriculture

Given the contentious debate on immigration, this study develops a dynamic model to analyse the effects of stricter border and domestic enforcement and streamlining the guest‐worker programme on cross‐border migration from Mexico, employment and production in US labour‐intensive and Mexican agriculture and the US and Mexican wage rates. The model incorporates labour‐leisure decisions of Mexican workers and labour market dynamics and linkages. The findings show stricter border and domestic controls exacerbate the labour‐shortage problems and reduce the US agricultural production. Streamlining the guest‐worker programme provides a steady supply of farm workers and has negligible impact on the US wage.
