The beneficial effects of generous unemployment benefits on profits and employment

Theories of the labor market generally predict that high unemployment benefits put upward pressure on wages, thus diminishing the profitability of employing labor and exacerbating unemployment. It remains to be explained why firms agree to contribute to generous schemes (replacement rates for general schemes in Europe and US are in the range 50–85%) that they are often willing to supplement (with sector- or firm-specific schemes that may involve even 100% replacement and long benefit duration). An answer can be found by including in the shirking–efficiency wage model, the hypotheses that workers are risk-averse and that those discharged for misconduct are not eligible to benefits. It is then optimal for risk-neutral firms (and for employment) to introduce an insurance scheme with full income coverage and with a duration limited only by the workers' participation constraint (there is no trade-off between level and duration of benefits). The more difficult it is to detect and fire shirkers, the higher is the rent workers enjoy above the competitive wage and the longer is the benefit duration consistent with the participation constraint. This result can be interpreted as a complementarity between the strictness of employment protection legislation (EPL) and the duration of benefits, which seems to conform with broad patterns observed in primary vs. secondary employment and in continental Europe vs. Anglo-Saxon countries.     

Minimum wage or negative income tax: why skilled workers may favor wage rigidities

In this article, we analyze the political choice of the extent and means of income redistribution between high and low-skilled workers. Redistributive tools encompass both fiscal transfers (a negative income tax) and a minimum wage requirement. We assume the use of fiscal instruments alone to be the first-best means of redistribution. We show that high-skilled workers may favor a second-best, minimum wage requirement because it increases unemployment, hence raising the marginal cost of redistribution, and creates a justification for them to moderate low-skilled workers’ claim for redistribution.      

Unemployment dynamics in an OLG economy with public pensions

Pension benefits in old age establish a disincentive to save in youth, thereby yielding lower levels of capital stock and the wage rate. As a result, the trade union has an incentive to change the composition of its two targets: employment and the wage rate. This paper develops a model that includes employment effects of public pensions via capital accumulation and union wage setting. Within this framework, we consider how contribution rates to the pension system influence the level and time path of the unemployment rate. It is demonstrated that (1) a higher contribution rate results in a lower unemployment rate, and (2) the economy with a high (low) contribution rate experiences monotone convergence towards (oscillatory convergence towards or a period-2 cycle around) the steady state.

Classical and Keynesian unemployment in Austria

The labor market in a macroeconometric model of Austria is used to determine the natural unemployment rate, full-employment (F.E.) output, and the F.E. real wage for 1966–92. Gaps between actual and F.E. variables are examined analytically and historically. Observed unemployment is decomposed into natural, hidden, classical, and Keynesian components. Classical unemployment is associated with the real wage gap, while Keynesian unemployment depends on the output gap. A rise in the natural rate is found to account for almost all of the increase in unemployment between 1966–74 and 1975–81, but an increase in Keynesian unemployment is the major factor in the rise of unemployment between 1975–81 and 1982–92. A fiscal shock to the complete model is found to increase real GDP for a year or two, reducing Keynesian unemployment without an appreciable rise in classical unemployment; the wage gap is eventually increased, however, producing a modest rise in classical unemployment.A lengthier version of this paper was presented at the Annual Meeting of the Austrian Economic Association, Graz, April 14–16, 1993. The generous finacial support of the Jubiläumsfonds of the Austrian National Bank for the research of which this paper is a part is gratefully acknowledged.     

Patterns of technical change: a geometrical analysis using the wage–profit rate schedule

In this paper we examine some basic stylized facts of economic growth according to the modern restatement of the classical theory of income distribution. In particular, we make use of a wage–profit frontier in order to explore the patterns of technical change experienced by a set of 18 industrialized economies, during the last 40 years. Our main purpose is to document the evolution of technical change. Using empirical evidence from the Italian industry, we also make an attempt to provide an explanation to data from a classical perspective, alternative to the standard approach founded on the aggregate production function.     

How flexible are real wages in EU countries? A panel investigation

We estimate the degree of real wage flexibility in 19 EU countries in a wage Phillips curve panel framework. We find evidence for a reaction of wage growth to unemployment and productivity growth. The degree of real wage flexibility tends to be larger in the central and eastern European (CEE) countries than in the euro area; weaker in downturns than during upswings. There exists an inflation threshold, below which real wage flexibility is low. We also find that a part of the heterogeneity in real wage flexibility and unemployment may be related to differences in the wage bargaining institutions.     

国际失业属性理论回溯

失业属性是失业理论发展的重要观察视角.本文基于对失业属性的认识.从凯恩斯对劳动供求数量失衡的观察到\"后凯恩斯主义\"对劳动供求结构失衡的认识和人力资本理论对劳动供求质量失衡的认识,以及发展经济学对发展中国家工业化过程中劳动数量供给特殊性的观察,正是在人们对失业属性的认识逐步深化过程中,失业理论得到了不断发展.     

Unemployment accounts and employment incentives

We explore the far-reaching implications of replacing current unemployment benefit (UB) systems by an unemployment accounts (UAs) system. Under the UAs system, employed people are required to make ongoing contributions to their UAs and the balances in these accounts are available to them during periods of unemployment. The government is able to undertake balanced-budget interpersonal redistributions among the UAs. At the end of their working lives, people could transfer the remaining balances on their UAs into their pensions.We present an analytical framework to analyse the incentive effects of UAs and calibrate our model for the high high-unemployment countries of Europe. Our results suggest that this policy reform would significantly change people's employment incentives and could achieve reductions in unemployment without reducing the level of support to the unemployed.     

我国全要素生产率变化解构及区域收敛性分析

笔者利用Malmquist生产力指数将1991年~2007年间中国29个省(自治区、直辖市)的全要素增长率按照构成分解为技术变动和技术效率变动,并对区域技术效率的收敛性进行了分析。结果表明:(1)以1997年为界限,东部、中部和西部三大区域的全要素生产率和技术变动均呈现先升后降的趋势,而技术效率在整个研究期间都是逐步降低的。(2)技术变动解释了全要素增长率区域差异的75%,技术效率变动则解释了剩余的25%。1997年之前的全要素生产率及其构成因素的变化有利于缩小地区生产差距,1997年之后则成为区域差距扩大的重要原因之一。(3)29个省份之间以及三大区域内部各省份之间的技术效率随时间变化均呈现出明显的发散趋势。     

Labor market shocks and retirement: Do government programs matter?

This paper argues that labor market conditions are an important and often overlooked determinant of retirement transitions. In our analysis, we examine how the unemployment rate affects retirement and whether the Social Security (SS) system and Unemployment Insurance (UI) system influence how older workers respond to labor market shocks. We use pooled cross-sectional data from the March Current Population Survey (CPS) in our analysis. We find that downturns in the labor market increase retirement transitions and that the magnitude of this effect is comparable to that associated with moderate changes in financial incentives to retire and to the threat of a health shock facing older workers. Interestingly, retirements only increase in response to an economic downturn once workers become SS-eligible, suggesting that retirement benefits may help to alleviate the income loss associated with a weak labor market. We also estimate the impact of UI generosity on retirement and find little consistent evidence of an effect. This suggests that in some ways SS may serve as a more effective form of unemployment insurance for older workers than UI.     

NOMINAL WAGE INDEXATION,QUASI‐EQUILIBRIA AND REAL WAGE DYNAMICS

In contrast to the traditional static approach to indexation, this paper analyses the dynamic consequences for real wages of the mechanism that links nominal wages to inflation. Revisiting a contribution by Dehez and Fitoussi on macroeconomic fluctuations , I analyse a monetary overlapping generations small open economy in which full indexation is interpreted as the occurrence of a dynamic ‘quasi‐equilibrium’. In the suggested framework, the nominal wage is linked to the inflation rate by a specific indexation formula whose shape relies on unions' bargaining positions. Assuming a constant peg for the real interest rate and the superneutrality of money, I show that the economy has a unique long‐run quasi‐equilibrium allocation whose stability depends only on the behaviour of the monetary authority. Moreover, I show how the operating of a ‘wage‐aspiration effect’ might lead to the persistence of involuntary unemployment.     

FDI in agricultural land, welfare and unemployment in a developing economy

The paper purports to examine the consequences of foreign direct investment (FDI) in agricultural land in a developing economy using a three-sector general equilibrium model with simultaneous existence of unemployment of both skilled and unskilled labour. The analysis finds that FDI in agriculture does not only improve national welfare unequivocally but also mitigates the unemployment problem of both types of labour. The paper theoretically justifies the desirability of flow of FDI in agriculture in the developing economies.     

中国技术进步偏向性的测算与分析

借助不变替代弹性生产函数,利用1985—2013年中国的相关数据,测算了中国技术进步的总体偏向性以及资本增强型技术进步和劳动增强型技术进步的变化速率。结果表明:资本与劳动的替代弹性约为0.402,资本与劳动呈现互补特征,且中国的技术进步呈资本偏向性。指出:从技术进步偏向看,独立自主的发展方针、实现国家工业化的目标以及资本和技术的缺乏共同导致了目前中国的技术进步偏向;中国工业化向高技术发展仍会加强技术进步的资本偏向性,并将引发一系列问题。认为短期内中国仍需维持一定规模的传统劳动密集型产业,长期应大力发展人力资本密集的现代服务业等第三产业。
