ORGANIZATIONAL CHANGE,SKILL FORMATION,HUMAN CAPITAL MEASUREMENT: EVIDENCE FROM ITALIAN MANUFACTURING FIRMS

Abstract This paper emphasizes the role of labour demand as a determinant of human capital formation. After a section in which the alternative conceptions on the functioning of labour markets are presented and different ways of measuring human capital are compared, an applied analysis is carried out in which we provide a labour‐demand‐oriented measure of human capital, as defined by the amount of specific skills firms generate through work‐based training (WBT) activities. By merging three rich firm‐level datasets, we estimate the impact of a set of variables supposed to affect both the propensity to invest in WBT and the intensity of training within the Italian manufacturing industry over the period 2001–2005. Special attention is devoted to the variables characterizing within‐firm organization of knowledge, organizational change and the formation of competence pipelines: among them, innovation, internationalization commitment, out‐sourcing and new hirings. The estimates show that the effect of innovation on WBT is higher when the introduction of new technologies is supported by organizational innovations. When looking at the nature of WBT, we investigate the different determinants of the firms' propensity to provide both in‐house and outside training. We measure training intensity in terms, respectively, of the number of provided training activities, private and total training costs and share of trainees.     

A SURVEY OF TRADE AND WAGE INEQUALITY: ANOMALIES,RESOLUTIONS AND NEW TRENDS

This paper surveys recent studies on trade and wage inequality. We first introduce some trade‐based explanations for increased wage inequality. There are, however, a number of criticisms of this line of thought based on the ‘trade‐wage inequality anomaly’, the ‘price‐wage anomaly’, and the small volume of trade. Mainly due to these criticisms, trade‐based explanations for rising wage inequality have been limited in the economic literature. Rather, the primary explanations for wage inequality have been based on skill‐biased technological change. Some trade models, however, have weakened the above criticisms, and more economists now argue that the effect of trade, though relatively small compared to that of technological change, is more significant than generally believed. Finally, we attempt to link new trends in inequality, such as job polarization and within‐group inequality, to the trade and wage inequality literature.     

TAXATION AND THE USER COST OF CAPITAL

This paper provides a review of the concept of user cost and its determinants. Particular attention is given to the influence of taxation. The concept of user cost relates to the rental, the rate of return to capital, that arises in a profit maximizing situation in which further investment in capital produces no additional profit. This paper sets out in some detail the range of assumptions involved in obtaining alternative expressions for the user cost. The user cost refers to a before-tax capital rental, the rate of return that ensures that the (after-tax) cost of capital is equal to the post-tax returns over its life. Hence, associated with the user cost measure is an effective marginal tax rate. This can differ substantially from the statutory marginal rate applicable to the investor. A related effective average tax rate is also defined.     

MEASURING HUMAN CAPITAL AND ITS EFFECTS ON WAGE GROWTH

Abstract Ever since Mincer, years of labour market experience were used to approximate individual's general human capital, while years of seniority were used to approximate job‐specific human capital. This specification is restrictive because it assumes that starting wages at a new job depend only on job market experience. In this paper, I investigate the effects of human capital on wage growth by using a more flexible specification of the wage equation, which allows for a rich set of information on past employment spells to affect the starting wages. In addition, I endogenize the labour mobility decision. In order to illuminate the effects of human capital accumulation patterns on wage growth, I compare counterfactual career paths for representative individuals.     

INTERNAL AND EXTERNAL FORCES IN SECTORAL WAGE FORMATION: EVIDENCE FROM THE NETHERLANDS

ABSTRACT The purpose of this paper is to investigate the relative importance of internal (sector-specific) and external (labour market) forces in sectoral wage formation in the Netherlands (1967–90). The results show that wages are largely determined by external forces, although internal forces are significant as well. The impact of the number of insiders, which plays a role in unemployment persistance, is not significant. Separate estimation results show that the impact of internal forces and of unemployment is weaker in the industrial sectors than in the service sectors. This casts doubt on the presumption that insider power increases the impact of internal forces on wage formation.     

VOTING, INEQUALITY AND REDISTRIBUTION

Abstract.  This paper surveys models of voting on redistribution. Under reasonable assumptions, the baseline model produces an equilibrium with the extent of redistributive taxation chosen by the median income earner. If the median is poorer than average, redistribution is from rich to poor, and increasing inequality increases redistribution. However, under different assumptions about the economic environment, redistribution may not be simply rich to poor, and inequality need not increase redistribution. Several lines of argument are presented, in particular, political participation, public provision of private goods, public pensions, and tax avoidance or evasion.     

WAGE INEQUALITY IN TURKEY: DECOMPOSITION BY STATISTICAL REGIONS, 1980–2001

This paper analyzes wage inequality in the Turkish manufacturing sector annually from 1980 to 2001, and also provides some evidence for inequality in the post‐2001 period. Using the between‐groups component of Theil's T statistic, the paper provides more information on wage inequality. It decomposes the evolution of inequality by statistical regions – The Nomenclature of Territorial Units for Statistics – (i.e. NUTS‐1 and NUTS‐2). The decompositions show that inequality has increased since the late 1980s in the private sector both between regions of NUTS‐1 and NUTS‐2.     

THE RETURNS TO ENDOGENOUS HUMAN CAPITAL IN PAKISTAN'S RURAL WAGE LABOUR MARKET

This paper estimates the private returns to human capital in Pakistani rural labour markets. The rich data used permit inclusion of several dimensions of human capital and control for endogeneity resulting from investment in human capital. The results suggest that, without data on determinants of human capital, it would not be possible to disentangle the separate effect of each dimension of human capital on wage differentials nor to distinguish human capital explanations for wage differentials from signalling and credentialist models. With control for endogeneity of human capital and selectivity into wage employment, cognitive achievement, but not schooling attainment separate from cognitive achievement nor long-run health status, affects wage differentials.     

INEQUALITY AND HAPPINESS

In recent years there has been an accumulation of empirical evidence suggesting that individuals dislike inequality. The literature has built upon estimating the degree of this dislike as well as its causes. The use of self‐reported measures of satisfaction or well‐being as a proxy for utility has been one of the empirical strategies used to this end. In this survey, we review the papers that estimate or examine the relationship between inequality and self‐reported happiness to conclude that inequality correlates negatively with happiness in Western societies. Some of the surveyed papers identify particular sources of heterogeneity on preferences over inequality. The evidence for non‐Western societies is more mixed and less reliable. Notwithstanding that, trust in the institutions seems to play an important role in shaping the relationship between income inequality and subjective well‐being. We conclude with suggestions for further research.     

THE CIRCULAR RELATIONSHIP BETWEEN INEQUALITY,LEVERAGE, AND FINANCIAL CRISES

In this paper, we put into perspective the recent literature which points to inequality as a possible cause of credit bubbles, by reintegrating it into a more general analysis on the two-way relationship between inequality and finance. We focus more specifically on situations where high inequalities and widespread access to credit coexist, and argue that, even when institutions maintain more or less equal access to finance, there may be a dynamic, positive circular relationship between inequality and financial development. However, even if there is some evidence in the literature of a positive causal impact of inequality on credit, this does not preclude other important, cofounding factors. The conclusions concerning the distributional impact of finance are more ambiguous. A survey of the empirical literature highlights several issues that must be tackled. First, endogeneity: reverse causality and coincidental factors are major concerns. Second, the choice of consistent measurements for the key variables (both credit and inequality) has strong empirical implications, and must be grounded on relevant theoretical channels. Third, those circular dynamics have substantial policy implications for emerging economies, since an increasing number face a joint increase in inequality and credit.
