Relative underperformance Alla Turca

From 1960 to 2003, Turkey has underperformed relative to several Western economies, in terms of hours worked and output per hour. Our sectoral analysis illustrates two points. First, Turkey's large drop in hours is due to the fact that the substantial decline in agricultural hours has not been accompanied by a corresponding increase in nonagricultural market hours. Second, the sectoral composition of output is important for understanding Turkey's relatively weak rise in output per hour. We develop a simple model of structural transformation and home production to provide an account of Turkey's performance relative to the U.S. and Southern Europe. We find that the evolution of exogenous differences in sectoral productivity and taxes, between Turkey and the U.S., as well as Southern Europe, can account quantitatively for most of Turkey's relative underperformance to these regions.     

THE GINI CONCENTRATION INDEX: A REVIEW OF THE INFERENCE LITERATURE

More than a century ago, Corrado Gini proposed his well-known concentration index for measuring the degree of inequality in the distribution of income and wealth. His index is still extremely relevant and widely used in several fields of research and application. In this paper, we focus on the inferential properties of the Gini index, and discuss the main directions of analysis proposed in the literature. The aim of the paper is to provide a comprehensive review of the main developments on the inferential aspects of the Gini concentration ratio. We feel that this work can provide a valuable contribution to those scholars who are approaching the large amount of literature on the inferential properties of the Gini index.     

Unions and Gender Pay Equity in Academe: A Study of U.S. Institutions

This paper uses 1994-95 faculty salary data from over 1,100 four-year U.S. academic institutions, about one-fourth of them with collective bargaining agreements, to ask if faculty unions make a difference to gender pay equity. Average gender salary differences are negative at every rank and at every category of U.S. institution with or without collective bargaining agreement. Unions may improve gender salary differentials somewhat, particularly at the assistant professor level. There is no evidence that this gain will be lost at higher levels, and mixed evidence that further gains occur for women at the full professor level. The most pervasive and robust consequence of unions is to increase the positive impact that higher proportions of women at senior faculty ranks make on relative salaries at the assistant professor level. However, the influence of these higher-ranked women on gender salary inequalities at the associate and full levels is lower in union schools than nonunion schools. By reducing the flexibility of existing salary structures, collective bargaining apparently reduces the influence of senior women faculty on the salaries of current women faculty members while increasing their attention and influence at entry levels.     

Information And Communication Technology And The Measurement Of Volume Output And Final Demand - A Five-Country Study

Information and communication technology (ICT) products have undergone rapid technical change. Where quality improvements occur, they should be reflected in official price and quantity indices, otherwise there is a tendency to over-estimate price movements and under-estimate volume changes of ICT products. Statistical offices deal with this issue but the degree and nature of quality-adjustment of price indices of ICT products varies considerably between OECD countries. The present study simulates measurement effects on key economic variables (real output, private final consumption, government expenditure, investment, exports and imports) and productivity, under the assumption that the price indices of ICT products are fully quality-adjusted. The paper draws on a large selection of empirical studies to identify differences between quality-adjusted and unadjusted price changes and uses detailed information from input-output tables to assess their weights in final demand. Effects on GDP and its components are quantified for five selected OECD countries.

劳动力自由迁移为何如此重要?——基于代际收入流动的视角

未考虑人口迁移影响的代际收入弹性估计存在偏误。本文将人口迁移与区域特性纳入代际收入弹性估计方程,并运用迁移概率作为局部工具变量进行估计,发现迁移者的代际收入弹性不到未迁移者的一半。而当前我国代际收入流动的主要问题在于部分人群面临"代际低收入传承陷阱",他们可以通过迁移从而增加就业机会等方式摆脱这一陷阱,这至少可以使一代人免受代际低收入传承的困扰。进一步分析迁移对代际收入传递路径的影响,结果表明教育在可识别的代际收入传递路径中贡献最大,而迁移强化了这一影响。鉴于人口迁移对代际收入流动的重要影响,政府部门有必要进一步采取措施降低劳动力自由迁移的障碍,并合理分配教育资源,以增进社会公平程度。     

初次收入分配与技术进步——基于马克思主义经济学的视角

生产力概念的深化对于马克思主义的发展非常重要,考察初次收入分配与技术进步之间的关系是一个可行的切入点。在税收收入占比保持不变的情况下,劳动收入占比的下降意味着资本收入占比的上升。劳动收入占比的下降缩小了消费市场规模而抑制技术进步(消费效应),资本收入占比的提高使得企业技术投资面临更少的融资约束而促进技术进步(融资效应),初次收入分配与技术进步之间可能呈现出无关、线性或者倒U型关系,其具体关系要视消费效应和融资效应的相对强弱而定。基于中国省际面板数据的实证分析发现,中国初次收入分配与技术进步之间的关系呈现出倒U型关系,存在一个最有利于技术进步的初次收入分配格局,意味着当前需要同时保护劳动和资本的权利。     

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.

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.
