A Phillips curve interpretation of error-correction models of the wage and price dynamics

This paper presents a model of employment, distribution andinflation in which a modern error correction specification ofthe nominal wage and price dynamics (referring to claims onincome by workers and firms) occupies a prominent role. It isbrought out, explicitly, how this rather typical error-correctionsetting, which actually seems to capture the wage and pricedynamics of many large-scale econometric models quite well,is fully compatible with the notion of an old-fashioned Phillipscurve with finite slope. It is shown how the steady-state impactof various shocks to the model can be profitably conceived ofand interpreted in terms of (and to some extent even calculatedby means of) this long-run Phillips curve.     

Must we choose? European unemployment, American inequality, and the impact of education and labor market institutions

In the last 15 years, two equilibria have arisen in the advanced world. On the one hand, wage dispersion has widened in those countries where unemployment has remained low (with cyclical variations). On the other hand, wherever income inequality has remained unchanged, unemployment has shot upwards. To account for these distinct patterns, we develop a political–economic model showing that, controlling for the skills of the population, the effects of technological and trade shocks (that have affected OECD nations) that are contingent on the institutional rules in place. Economies with generous unemployment allowances adjust through subsidized unemployment. By contrast, low levels of social protection lead to less unemployment but wider wage dispersion. The level of qualifications of the labor force determines the extent of the adjustment for a given institutional arrangement. We derive, in turn, the institutional structure of each country from the political conditions in place at the time of the shock. The empirical part successfully tests the model for the sample of European regions and US states.

教育对地区内收入差距的贡献:来自上海微观数据的考察

作为人力资本的一个度量,教育对于收入差距的贡献一直受到广泛的关注,但却研究不够.本文借助上海市1431户家庭的微观数据,估计了一个包含教育变量的收入决定函数,然后在基于回归分析的收入差距分解框架内,运用最新发展起来的夏普里值过程(Shapley Value Approach),分解出了教育对于收入差距的贡献大小.通过比较发现,与地区间差距的情形不同,教育对于地区内收入差距而言是最重要的影响因素.     

贫困、经济增长与脱贫时间:基于中国城镇居民调查数据的分析

贫困指数是衡量社会总体贫困程度的指标,在众多的贫困指数中.本文选择具有良好性能的瓦特指数和由此派生出来的脱贫时间指数,分析了我国城镇上个世纪90年代以来的贫困变化趋势.研究发现,城镇贫困在1997年达到高峰,然后逐渐缓和;贫困人口的收入增长在初期能使脱贫时间迅速下降,但边际效果是递减的;贫困人口之间的收入分配不平等延长了脱贫时间:如果贫困人口的初始收入增加,会明显降低脱贫时间.     

Does the Effect of Inequality on Growth Present an Inverted U Curve？ --Empirical Evidences from Transition Economies

本文以7个代表性转型国家1986—2009年跨国面板数据为样本，利用面板数据模型分析了收入差距对经济增长影响轨迹是否呈倒U型曲线。研究结果表明，转型国家收入差距与经济增长之间存在倒U型曲线关系。即使在样本中除去收入差距较严重的中国数据，收入差距对经济增长影响的倒U型曲线的证据仍然存在。近似计算，基尼系数为0．42是收入差距对经济增长影响由正变负的拐点。本文还发现，经济自由度这一制度因素对中国经济增长有较大影响。中国政府应积极探索有利于缩小收入差距，促进经济增长的经济发展方式及制度环境，包括加大公共服务供给，健全社会保障体系，进一步推进国有企业改革，推进政府体制改革，推动市场化进程，纠正要素价格扭曲行为，打破垄断，深化税制改革，完善转移支付制度等。     

Wage Spillovers,Inter-regional Effects and the Impact of Inward Investment

Abstract

This paper evaluates the extent of inter-industry and inter-regional wage spillovers across the UK. An extensive body of literature exists suggesting that wages elsewhere affect wage determination and levels of satisfaction, but this paper extends the analysis of wage determination to examine the effects of inward investment in the process. Thus far the specific effect of foreign wages on domestic wage determination has not been evaluated. We employ industry- and regional-level panel data for the UK, and contrast results from alternative approaches to space-time modelling. Each supports the notion that such wage spillovers do occur, though assumptions made concerning the modelling of spatial interaction are important. Further, such wage spillovers are more widespread for skilled than for unskilled workers and also lower in areas of high unemployment.     

The Swedish third way: an assessment of the performance and validity of the Rehn-Meidner model

This paper analyses the functioning of the Rehn–Meidnermodel in Sweden and the validity of the model's underlying theory.Both sceptics and friends of ‘the Swedish model’have exaggerated the effects of active labour market policyand solidarity wage policy on employment, inflation and growth.However, these policies have contributed to the reduction ofhysteresis effects and wage differentials in Sweden. Furthermore,Swedish experiences confirm the Rehn–Meidner view thatpositive demand shocks and expansionary macroeconomic policiesmake it difficult to combine full employment with price stability,economic growth and equity even if central wage negotiationsare coordinated and trade unions willingly accept wage restraint.     

Labor supply in urban China

Using labor supply responses from 10,560 urban Chinese workers, two-stage least squares estimations identify positive compensated wage effects and negative income effects that are, for the most part, statistically significant. The gross wage effects are mostly positive but they indicate relatively low uncompensated labor supply elasticities. The compensated wage effects are much larger; these may be important in assessing the labor market consequences of reform policies that monetize non-pecuniary benefits. The significance of labor supply responses depends on individual responsibilities within the family; the effects are largest for women and non-household heads.

基于收入分布的收入差距扩大成因的分解

本文采用核平滑化的半参方法估计了1987年、1996年、2004年我国城市居民收入分布曲线,并且基于收入分布又进一步分解了导致城市居民收入差距扩大的主要原因。收入差距扩大的成因可以分为两类:一是劳动者的劳动力特点的普遍变化,如劳动者教育水平的提高,行业、职业分布的变化;二是对劳动力特点回报率的变化,如教育回报率的提高,各行业、职业回报率差异的扩大等。本文发现后者是导致收入差距扩大的主要原因。
