Wage,income and consumption inequality in Japan, 1981–2008: From boom to lost decades

In this paper we document the main features of the distributions of wages, earnings, consumption and wealth in Japan since the early 1980s using four main data sources: the Basic Survey on Wage Structure (BSWS), the Family Income and Expenditure Survey (FIES), the National Survey of Family Income and Expenditure (NSFIE) and the Japanese Panel Survey of Consumers (JPSC). We present an empirical analysis of inequality that specifically considers the path from individual wages and earnings, to household earnings, after-tax income, and finally consumption. We find that household earnings inequality rose substantially over this period. This rise is made up of two distinct episodes: from 1981 to 1996 all incomes rose, but they rose faster at higher percentiles; from 1996 to 2008 incomes above the 50th percentile remained flat but they fell at and below the 50th percentile. Inequality in disposable income and in consumption also rose over this period but to a lesser extent, suggesting taxes and transfers as well as insurance channels available to households helped to insulate household consumption from shocks to wages. We find the same pattern in inequality trends when we look over the life cycle of households as we do over time in the economy. Additionally we find that there are notable differences in the inequality trends for wages and hours between men and women over this period.     

ON THE USE OF FIRM FIXED EFFECTS AS A PRODUCTIVITY MEASURE FOR ANALYZING LABOR MARKET MATCHING

The present note evaluates the performance of firm fixed effects as a productivity measure when identified from wage regressions with two‐way fixed effects in matched employer‐employee data. This setting is frequently applied to study the matching between workers and firms. Exploiting wage and production data from a large administrative German data set, I find that the correlation between firm fixed effects (FFE) and total factor productivity is close to zero. Once TFP is used, the matching pattern is positive assortative, whereas the two‐way fixed effect technique yields the opposite result.     

WAGE PENALTIES AND SEXUAL ORIENTATION: AN UPDATE USING THE GENERAL SOCIAL SURVEY

This study uses data from the 1988 to 2006 General Social Survey (GSS) to examine the effects of sexual orientation on earnings. Previous research using the GSS has found that lesbians earn 18%–23% more than similarly qualified heterosexual women and that wage penalties for gay men are slightly larger than the premia for lesbians. Using behavioral definitions of sexual orientation based on the previous year and the previous 5 yr of sexual activity, we find the familiar wage premia/penalties for lesbian/gay workers in our ordinary least squares estimations, but we find that these wage differences are falling over time. Furthermore, in contrast to the earlier results, for our regressions over the entire sample period, correcting for differential selection into full-time work reduces the estimated penalties for unmarried gay men and eliminates the entire wage premium for all lesbians. There is now a sizeable, though imprecisely measured, penalty for some lesbians. ( JEL J1, J3, J7)     

Wage Setting, Wage Curve and Phillips Curve: The Italian evidence

The purpose of this paper is to investigate some issues of wage setting in order to assess if nominal inertia and wage flexibility characterise the Italian supply side, using multivariate cointegration models. Our estimates indicate that an explicit distinction between stationary and non-stationary variables and a joint analysis of long-run and short-run structure is crucial for achieving clearer results. To this end, we use quarterly time series data for industry sector 1976:1–1993:4. Interesting results have been found concerning the empirical evidence of a long-run wage curve and the existence of a Phillips curve, through adopting alternative order reduction of the I(2) wage and price variables. Moreover, some insights on regional (North-South) unemployment effects are pointed out and discussed.     

Firm heterogeneity and immigrant wage assimilation

This article investigates the role of job mobility in immigrant wage assimilation. I use longitudinal linked employer–employee data for Portugal to estimate the immigrant wage catch-up in log wage regressions with both individual and firm fixed effects. I show that moving to firms with higher wage premiums accounts for approximately 30% of the immigrant wage catch-up in the first years.     

Identification of Search Models using Record Statistics

This paper shows how record-value theory, a branch of statistics that deals with the timing and magnitude of extreme values in sequences of random variables, can be used to recover features of the wage offer distribution in conventional search models. Using National Longitudinal Survey of Youth (NLSY) wage data, I show that the data are not compatible with specifications for the offer distribution characterized by extreme negative skewness. In addition, I show that my approach can be used to construct a bound on the returns to job seniority. My results suggest that job seniority plays only a minor role in the wage growth of the workers surveyed in the NLSY.     

国有单位工资结构及其就业规模变化的收入分配效应:1988—2007

本文使用1988年、1995年、2002年、2007年CHIP城镇入户调查数据考察国有单位工资结构及其就业规模变化的收入分配效应。为此,本文采用了分位数回归方法、以多重分位数回归为基础的Machado&Mata(2005)反事实分解方法及作者扩展了的方法。各结果表明:国有企业就业份额大幅度下降导致中国城镇工资收入差距显著下降;然而国有企业减员增效改革完成以后,国有企业工资高于非国有企业的幅度及其不合理部分大幅度上升,其结果是城镇工资收入差距扩大。     

The effect of minimum wage on poverty

To the best of my knowledge, the minimum wage's influence on poverty in Russia has never been investigated. Russian data provide a unique opportunity for studying the effects of the minimum wage on poverty, given significant increases in the minimum wage in recent years, almost complete coverage, and a high representation of full-time workers in poor households. This article examines the effect of the minimum wage on the incidence of poverty and the transitions into and out of poverty in Russia using data from the Russia Longitudinal Monitoring Survey of Higher School of Economics (RLMS-HSE) from 2006 to 2011. The results indicate that the minimum wage in Russia had moderate poverty-reducing effects.     

Far away from a skill-biased change: falling educational wage premia in Italy

In this article we apply quantile regressions to investigate the evolution of Educational Wage Premia (EWP) in Italy from 1993 to 2004. Using the Survey of the Household Income and Wealth (SHIW, Bank of Italy) and different classifications for educational attainments, we show that, in the private sector, EWP have generally decreased over time, considering both continuous and categorical specifications for education, at all quantiles of the wage distribution. Different patterns are observed in the public sector, where EWP remain basically stable over time. A number of robustness checks and various econometric specifications are also applied in order to address sample selection issues. Our findings provide additional evidence in favour of the thesis that the increasing patterns in inequality and EWP, and the related interpretations concerning skill-biased changes, are much less pronounced in continental Europe than in Anglo-Saxon countries.     

The establishment-size wage premium: evidence from European countries

This study examines the magnitude and determinants of the establishment-size wage premium in five European countries using a unique harmonised matched employer–employee data set (the 1995 European Structure of Earnings Survey). This data set enables to test the validity of various traditional explanations of the size wage gap (i.e. the labour quality hypothesis, the theory of compensating wage differentials, the role of monitoring and institutions) and of more recent hypotheses (i.e. size differences in job stability and in the concentration of skilled workers). We find some support for traditional explanations, but there remains a significant wage premium for workers employed in large establishments. Further results indicate that the magnitude of this premium fluctuates substantially across countries and appears to be negatively correlated with the degree of corporatism.     

REMOVING THE “VEIL OF IGNORANCE”: NONLINEARITIES IN EDUCATION EFFECTS ON GENDER WAGE INEQUALITIES

A large literature studies the mean gender wage gap in developing countries and finds mixed evidence about the role of education policies in closing gender earnings inequalities. We contribute to this literature by exploring two types of nonlinearities in wage earning regressions: (1) nonlinearities on the effects of education on expected earnings along the distribution of education endowments; and (2) heterogeneities on the contributions of education to the gender wage gap at different quantiles of the wage distribution. Our analyses provide new insights on how these nonlinear effects can be used to set up better targeted gender and development policies. (JEL I26, C14)     

中国大城市的工资高吗?——来自农村外出劳动力的收入证据

运用2008年农村外出劳动力的收入数据(RUMiCI),本文分析我国不同规模城市的工资升水是否存在,并探讨其产生的内在机制。研究发现控制住劳动者的可观测能力特征,城市规模的工资升水并不大,而进一步考虑劳动者的不可观测能力特征和选择偏差问题,大城市劳动者的收入优势不再存在,甚至可能出现收入劣势。大城市的互动效应和学习效应只部分地得到证明。论文为城市聚集的劳动力市场影响、劳动力在不同规模城市间的合理配置以及城市间劳动者收入差距的缩小等问题提供了启示。     

Downward nominal wage rigidity in Canada: Evidence from micro‐level data

We assess the importance of downward nominal wage rigidity (DNWR) in Canada using employer‐level administrative data from the major wage settlements (MWS) and household‐based survey data from the Survey of Labour Income Dynamics (SLID). MWS data cover large unionized firms in Canada, while SLID is a rich rotating panel representative of the employed population in Canada. Combining both sources of information allows for an extensive analysis of DNWR in the Canadian labour market. We find large shares of wage freezes and smaller shares of wage cuts in both MWS and SLID. Shares of freezes are higher at lower CPI inflation rates, based on provincial data. These observations are consistent with the presence of DNWR. DNWR in Canada appears to be larger than in other countries such as the United States, the United Kingdom and European countries. The incidence of DNWR is heterogeneous across firms’ and workers’ characteristics. Wages report less DNWR over longer horizons.     

MINIMUM WAGES AND GROSS DOMESTIC PRODUCT

This study is the first to explore the relationship between minimum wage increases and state gross domestic product (GDP). Using data drawn from the Bureau of Economic Analysis (BEA) and the Current Population Survey (CPS) from 1979 to 2012, I find no evidence that minimum wage increases were associated with changes in overall state GDP. However, this null finding masks substantial heterogeneity in the productivity effects of minimum wages across industries and over the business cycle. Difference‐in‐difference‐in‐difference estimates suggest that a 10% increase in the minimum wage is associated with a short‐run 1% to 2% decline in state GDP generated by lower‐skilled industries relative to more highly skilled industries. This differential appears larger during troughs as compared to that during peaks of the state business cycle. (JEL J3, J4, L5)     

互联网使用与工资收入差距*——基于CHNS数据的经验分析

基于2004—2011年的中国营养与健康调查数据（CHNS）,本文使用最小二乘法和控制自选择偏差的倾向性得分匹配法详细估计了互联网使用对工资收入的影响。结果表明,互联网使用对个体工资收入有积极的影响,尤其对于拥有高中学历的个体而言,这种影响更大。本文进一步使用基于RIF回归的FFL分解方法考察了互联网使用对工资不平等的影响。本文发现,2004—2011年间互联网使用比例的增加降低了整体工资不平等,且使用过互联网的高中学历人员比例增加有助于降低高工资与中等工资收入人群的工资差距。同时,互联网使用收益率的下降也有助于降低工资不平等,尤其有助于降低高工资与中等工资收入人群之间的工资差距。因此,普及互联网使用,尤其是提高低收入群体的互联网使用比例和普及该群体的高中阶段教育对于抑制不平等的扩大有重要的意义。     

Caste discrimination in the Indian urban labour market: An econometric analysis

This paper uses Degree Holders and Technical Personnel Survey of India to examine the wage gap between Non-Scheduled Castes/Tribes(NSC) and Scheduled Castes/Tribes(SC/ST). Separate wage equations, corrected for selection bias, are estimated for NSC and SC/ST. The parameter estimates of the wage equations were decomposed into ‘endowment’ and ‘treatment’ components using the familiar Oaxaca Decomposition Method. A separate account was also made to analyze the interaction between occupational attainment and the wage differential using the extended decomposition method. The main conclusion from the econometric results are: (a) the endowment difference is higher and discrimination causes 15 per cent lower wages for SC/ST as compared to NSC; (b) the discrimination coefficient is negative in the public sector whereas it is positive in the private sector; (c) intraoccupational wage effects dominate. The higher endowment difference in developing countries like India implies that the pre-market discriminatory practice with respect to education, health and nutrition are more crucial than labour market discrimination.

Is There a Glass Ceiling over Germany?

This paper analyzes the gender wage gap across the wage distribution using 2010 data from the German Statistical Agency. I investigate East and West Germany and the public sector separately to account for potential heterogeneities in wage gaps. I apply unconditional and conditional quantile regression methods to investigate the differences between highly paid men and women in distributions conditional and unconditional on covariates. The results indicate increasing gender wage gaps in all estimations, suggesting that there is indeed a glass ceiling over Germany even after controlling for a large set of observable characteristics (including occupation and industry). This finding is even more pronounced when also taking bonus payments into account.     

Aid Disaggregation and the Public Sector in Aid-Recipient Economies: Some Evidence from Cote D'Ivoire

The present paper examines the impact of different aid types, namely project aid, program aid, technical assistance, and food aid on the fiscal sector of the aid‐recipient economy by using time‐series data for Côte d’Ivoire over the period 1975–99. Our empirical results show that when a single value (or aggregated) for aid is used, foreign aid is fully consumed in the case of Côte d’Ivoire. However, results obtained under the assumption of aid heterogeneity clearly suggest that the government responds differently according to the nature of the aid inflows. Our approach tries to illuminate the response of the aid‐recipient government to different categories of foreign aid inflows and the empirical findings clearly demonstrate the importance of the aid disaggregation approach for delving deeper into aid effectiveness issues.     

The Return to Caring Skills: Gender,Class, and Occupational Wages in the US

Feminist economics has contributed to the understanding of the economic importance of care work. Most studies find a wage penalty associated with caring occupations. This study extends the feminist research on care work beyond caring occupations by identifying specific caring skills and activities derived from the 2014 O*NET job-evaluation data. Four caring skills – (1) Assisting and Caring for Others, (2) Establishing and Maintaining Interpersonal Relationships, (3) Service Orientation, and (4) Social Perceptiveness – were used in ordinary least-squares and quantile wage regressions for 623 occupations in the United States. Findings indicate that the return to caring and assisting skills results in a wage penalty for low-wage workers but a wage premium for workers in high-wage and male occupations. By identifying the impact of gender and class on the economic return to particular caring skills, the study broadens the understanding of care work, especially in relation to US wage inequality.     

Wages in a growing Russia

The robust Russian economic recovery after the 1998 financial crisis raised the economic standing of the population, especially for lowly paid workers, most of whom are women. In this paper I use the Russian Longitudinal Monitoring Survey from 1996 through 2002 to ask whether this helped to reduce the gender wage gap. I first focus on those whose wages are paid in full. Next, I ask about the gender composition of wage arrears as the overall extent of wage arrears dropped from 60 to 20 per cent after the 1998 crisis. I show that a temporary widening of the overall gender wage gap in 2000 is due to low‐wage women becoming more likely to receive their wages in full than low‐wage men. Except for this effect, the male–female pay difference in Russia exhibits a stable pattern.
