中国劳动力市场名义工资粘性程度的估算

本文完成了对中国劳动力市场名义工资粘性程度的首次估算,发现中国的名义工资粘性处于世界较低水平。这具有重要的宏观政策含义:一方面表明中国的劳动力市场具有很强的"自我调节"经济波动的特性,另一方面说明中央银行扩张性的货币政策将更多地带来物价水平上涨,而不是产出增加。在此基础上,本文还区分了劳动者的收入、工龄、户口、企业类型、行业等特征,对不同人群的工资粘性进行了细致测算。进一步,本文创新地区分并估算了名义工资的向上粘性与向下粘性,发现自2002年以来,中国劳动力市场的向下粘性不断增大,而向上粘性的变化趋势并不明显。     

试论凯恩斯经济学研究方法的新取向

随着主流凯恩斯主义经济学的流行，原创性的凯恩斯经济学实际上已经“夭折”了，它的革命思想并没有得到真正的阐发与传播。从范式角度比较和分析原创性凯恩斯经济学和三个凯恩斯经济学流派之间的本质关系后发现，后凯恩斯经济学对原创性凯恩斯经济学的研究提供了重要启示；但是后凯恩斯经济学的理论局限性说明，必须探索一种新的研究方法，即一种制度的演化的经济学范式，从而推动凯恩斯经济学的进一步发展。     

累进性劳动所得税、失业波动与内生稳定器——一个动态新凯恩斯主义的视角

将累进性劳动所得税引入NKMP—DSGE模型中考察失业波动与累进性税收的宏观效应。贝叶斯脉冲响应函数表明,外生冲击对于就业与失业具有不同的冲击效应,因而忽略失业可能引起结论的偏误;失业的贝叶斯冲击分解结果表明,货币政策冲击是推动我国失业波动最重要的力量,并且我国劳动力市场存在显在的“失业回滞”。进一步,通过模型比较发现,累进性劳动所得税具有内生稳定器的作用。在失业问题日益严峻的背景下,采用对劳动力市场做出反应的货币政策机制以降低失业,并使用内生稳定器缓和经济波动,将可能实现降低失业与缓和经济波动的双重效果。     

From equilibrium to disequilibrium: the genesis of Don Patinkin's interpretation of the Keynesian theory

This paper explains the reasons that led Don Patinkin to interpret the Keynesian theory in a disequilibrium perspective. We claim that the author adopted this position because he believed that the assumption of wage rigidity misrepresented the concept of involuntary unemployment and that, consequently, it had to be rejected. It is shown that this conclusion resulted from the confrontation of Patinkin, during the writing of his Ph.D. thesis, with the interpretations of the Keynesian theory argued respectively by Lange, Klein and Modigliani.     

Unemployment Benefits, Contract Length and Nominal Wage Flexibility

In a bargaining model, we show that a decrease in the unemployment benefit level increases not only equilibrium employment, but also nominal wage flexibility, and thus reduces employment variations in the case of nominal shocks. Long‐term wage contracts lead to higher expected real wages and hence higher expected unemployment than short‐term contracts. Therefore, a decrease in the benefit level reduces the expected utility gross of contract costs of a union member more with long‐term than with short‐term contracts, thereby creating an incentive for shorter contracts. Incentives for employers are shown to change in the same direction.     

The Cambridge School of Keynesian Economics

There have been strong ties between the Cambridge Journal ofEconomics (CJE) and the Cambridge School of Keynesian Economics,from the very beginning. In this paper, the author investigatesthe environment that saw the birth of the CJE at Cambridge (UK),in 1977, and the relationship that linked it to the direct pupilsof Keynes. A critical question is explicitly examined: why didn'tthe ‘Keynesian revolution’ succeed in becoming apermanent winning paradigm? Some behavioural mistakes of themembers of the Keynesian School may explain this lack of success,but only to a certain extent. In any case, there were and therestill are remedies too. But what we are inheriting is a uniqueset of analytical building blocks (the paper lists eight ofthem) that makes this School of economics a viable (and in somedirections definitely superior) alternative to mainstream economics.Admittedly, there is some important work still to be done. Thepaper highlights the need for a two-stage approach, addressingpure theory and extensive institutional analysis. It is arguedthat a combination of the two would strengthen the coherenceof the theoretical foundations, and at the same time would providea fruitful extension of economic analysis to empirical, institutionaland economic dynamics investigations.     

Parasitic-Industries Analysis and Arguments for a Living Wage for Women in the Early Twentieth-Century United States

This paper examines arguments by activists and economists surrounding attempts to establish minimum wages for women in the United States in the Progressive Era. In particular, the paper focuses on analyses based on Beatrice and SidneyWebbs' argument that industries paying less than a living wage were "parasitic" on the society, a net drain on macro-efficiency. This analysis, widely accepted among economists of the time, viewed women as particularly vulnerable workers facing labor markets that were institutionally constructed and predatory. Unequal gender roles, employer power, and the absence of collective bargaining could all result in wages that were socially unacceptable as well as economically nonoptimal. These debates offer insights for modern feminist wage theories, and for current living wage campaigns.     

Unemployment and the economics of gradualist policy reform

This paper investigates the efficiency of adjustment to economic reform programs when the cost of adjustment arises from high unemployment that can be generated as contracting sectors shrink faster than expanding sectors grow. Under plausible assumptions on the adjustment process, the speed of adjustment to “shock therapy” reforms is shown to be excessively rapid, and the rate of unemployment to be excessively high during the transition to the new equilibrium. The authorities can improve the efficiency of the adjustment by removing the distortion gradually, rather than abruptly. Gradualism has beneficial income distributional, as well as efficiency properties, because it improves welfare of the unemployed, who are necessarily the least advantaged social group in this model.     

Intermediate macroeconomics: The importance of being post Keynesian

Post Keynesians should not be afraid to teach what they believe represents the best explanation of macroeconomic fluctuations. Our colleagues in the mainstream certainly are not and, realistically speaking, it is hard to imagine that any student would be handicapped by not having had a full dose of IS-LM, the accelerationist hypothesis, Phillips Curves, and so on. Furthermore, there may not be a more opportune time to introduce post Keynesianism to undergraduate students with Neoclassicals still recovering from their inability to explain the financial crisis. This article argues for a post Keynesian-focused intermediate macroeconomics and offers a sample plan. It reviews the state of post-financial crisis mainstream macro teaching and references pedagogical literature in showing how a post Keynesian transformation and reorganization can be made most effective.     

The New Keynesian business cycle achievements and challenges

The New-Keynesian (NK) business cycle model has presented itself as a potential “workhorse” model for business cycle analysis. This paper seeks to assess afresh the performance of the baseline NK model and its various extensions. The main theme of the paper is that although the dynamic NK literature has secured a robust defence to criticism arising, inter alia, on account of lack of microfoundations, it still has a long way to go in terms of providing a fully satisfactory model of the business cycle. In this regard, it is conjectured that explicitly accounting for the role of heterogeneity in business-cycle dynamics could lead towards a viable solution.

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.     

Price rigidity and market-clearing: a conceptual clarification

This article tests the view (derived from Hicks and Patinkin)that non-market clearance may be caused by slow adjustment (‘processrigidity’). There are models where market-rationing ispresent and derives from some form of rigidity, but this rigiditycannot be considered as process rigidity. It is similarly possibleto accommodate the idea of process rigidity within the Marshallianresearch programme. What is missing is that market-rationingmight be its corollary. The reason such a causal link is oftenbelieved to exist lies in a generic use of the concept of rigidity,used to designate alternative and incompatible phenomena: ‘exogenousend-state rigidity’ and ‘equilibrium end-state rigidity’,as well as process rigidity. It is true that these first twoforms of rigidity create market rationing. The belief that slowadjustment also generates market rationing results from theunwarranted extension to process rigidity of conclusions whichare only valid for the first two.     

凯恩斯革命中的创新与继承

凯恩斯革命是从理论、政策、方法三个层面展开的。货币非中性论、货币供给外生论、对萨伊定理的彻底否定构成凯恩斯革命的理论基础;财政政策和货币政策是凯恩斯革命赖以实现的政策工具;对经济学研究对象的纠偏、破除传统的两分法和首创货币经济学是凯恩斯革命赖以完成的方法论。与此同时,《通论》内在逻辑上的不一致性,与经典学派崇尚经济自由传统的趋同,决定了凯恩斯革命中的继承。由于经济运行的常态是非充分就业均衡,《通论》必然具有永恒价值。     

Downsizing, wage inequality and welfare in a developing economy

This paper focuses on the cost cutting effects of firm downsizing in a developing economy. Using a dualistic production structure to depict a developing economy, the impacts of downsizing on wage inequality and social welfare are examined. Downsizing is revealed to not only narrow the wage gap between skilled and unskilled labor but also to raise the level of manufactured output and reduce the unemployment ratio in the urban sector. These effects improve the social welfare of the economy.     

新凯恩斯主义视域下中国失业的持续性——理论研究与数值模拟分析

文章通过采用工资加成,将失业变量引入新凯恩斯主义货币政策理论分析框架,并基于校准的模型考察了技术冲击、偏好冲击和货币政策冲击对失业持续性的影响。研究表明,三种外生冲击均对失业产生影响,相对于技术冲击与偏好冲击,货币政策冲击对失业的持续性具有更强的影响。据此,文章进一步考察了失业的持续性对影响失业的主要参数的敏感度。结果表明,劳动偏好系数和产出对劳动的弹性系数的变化不影响文章的基本结论,但对不同的外生冲击,不同的劳动偏好系数和产出对劳动的弹性系数对失业的持续性及失业超调的幅度会产生不同的影响。     

Progressive Taxation and Wage Setting: Some Evidence for Denmark

The proposition that a progressive tax system contributes to wage moderation is studied using Danish earnings data disaggregated by occupation, gender and earnings level. Our main conclusions are that income-tax progression affects wage setting, but whether it moderates or exaggerates wage pressure is income dependent. An increase in progressivity reduces the pre-tax earnings of middle-income workers (manual male workers and moderate income earners among both male and female non-manual workers). The reverse is found for high-income earners (non-manual male workers), in that an increase in progressivity tends to raise pre-tax earnings. Finally, there is no significant effect of tax progressivity on the wages of low-income earners.

市场歧视对城镇地区性别工资差距的影响

本文使用基于分位数回归的反事实分析方法研究了中国城镇地区的性别工资差距问题,发现了以下三个结论:第一,性别工资差距在工资分布不同位置上存在不对称现象。从横截面数据来看,在工资分布顶端性别工资差距较小,在工资分布末端性别工资差距较大。从时序数据来看,在工资分布顶端性别工资差距越来越小,在工资分布末端性别工资差距越来越大。第二,性别工资差距在横截面数据上表现出不对称现象的原因是,女性在工资分布顶端受到的歧视程度低,在末端受到的歧视程度高。第三,性别工资差距在工资分布末端越来越大的原因是,女性受到的歧视程度越来越高;在工资分布顶端越来越小的原因是,男性和女性个人特征方面(如受教育水平)的差别越来越小。     

An additional explanation for the variable Keynesian multiplier: The role of the propensity to import

This article analyzes the concept of the Keynesian multiplier from a new perspective. Several recent studies have shown that the fiscal multiplier is endogenous to the level of economic activity, increasing during recessions and decreasing during the boom. Here, we provide some evidence, explaining this variability over the business cycle, based on the overreaction of aggregate imports. Then, we apply the concept of endogenous propensity to import, varying with capacity utilization, to a neo-Kaleckian model of growth and distribution. We perform some simple simulations showing that the Keynesian multiplier increases during a recession, which logically does not advocate a reduction in public spending when the economy is in crisis.     

The Effects of Immigration on Regional Unemployment Rates in The Netherlands

The impact of immigration on the change in the unemployment rate in the Netherlands is analyzed using panel data from 26 labor market regions from 1996 through 2003. This study measures immigration through the year-to-year change in the foreign population, paying particular attention to immigrants of non-Western origin. Other variables controlling the composition of the local labor market include: occupation shares, the fractions of workers employed in high- and low-skilled jobs, the fractions of female workers, part-time employees, labor force participants over the age of 55, educational attainment shares, and population density. The ordinary least squares (OLS) results indicate a change in the foreign population in the labor force led to a statistically significant increase in the upward volatility of Dutch unemployment rates while the change in the non-Western share had no significant effect.

Unemployment and Migration: Does Moving Help?

The migration behaviour of the unemployed in Finland is analysed in terms of the causal effect of moving on individual employment status. In 1994, 17 percent of the labour force was unemployed and the unemployment rate exhibited a very slow decline in 1994–1996. Over half of those who were unemployed at the end of 1994 were still unemployed two years later. The propensity to find a job is somewhat greater among migrants. However, the positive effect of moving diminishes once other personal characteristics are accounted for. Moreover, when controlling for endogenous migrant selectivity, an insignificant or even negative effect on employment status emerges. This indicates that the relatively better "quality" of the migrants (e.g. age, education, human capital and unobserved ability), rather than the act of moving itself, causes an improvement in re–employability. Hence, migration alone may not be a very effective mechanism for alleviating individual unemployment.
