Education, Intergenerational Mobility and Inequality

We review the economic literature on the impacts of the several dimensions of education upon intergenerational inequality persistency. It is firstly outlined that the critical increase in the population education level in all countries has not come with lower inequality. The basic tools of education and intergenerational mobility modelling are subsequently exposed (OLG, education functions, education decision making etc.). The following two theoretical sections analyse the cases in which education leads (i) to human capital convergence in the long term and (ii) to social stratification with the emerging of under-education traps (situations in which certain dynasties remain continuously under-educated). A simple modelling of both cases is proposed for two types of educational decisions, one based on the family expenditure on education and the other on the time spent for education. The factors that generate social stratification and under education traps are especially underlined. The empirical literature on the determinants of educational attainment and intergenerational mobility is finally reviewed. This reveals the crucial impact of family backgrounds on educational attainment in all countries. It also demonstrates huge and lasting differences across countries in terms of intergenerational mobility.

Growing Income Inequalities in Advanced Countries

In this paper, we survey the literature that studies the issue of growing inequalities in advanced countries (the North). We firstly unveil the main facts concerning widening inequality in the North and we underlie the differences between countries and groups of countries. We put forward the concomitance of the rise in inequality with three key developments that are the three major explanations given to growing inequality: globalization, skill biased technological progress and institutional changes. We finally expose the mechanisms behind each explanation and examine the results of the empirical works that attempt to appraise their respective impacts. The overall diagnosis is that the three explanations are valid but (i) their weight may substantially differ across countries and sectors, and (ii) they interact in the determination of inequality.

Inequality in emerging countries

We review the theoretical and empirical economic literature upon income inequality in emerging countries. We firstly describe the main observed developments and show that these are rather diverse across countries and developing regions. We subsequently expose the main theoretical mechanisms. We make a distinction between the traditional approaches (Kuznets, Lewis, Stolper-Samuelson) and the new explanations. In the latter, globalization and globalization-driven technological changes are at the core of the analyses. Both approaches bring out several opposite mechanisms. Finally, the empirical estimates display rather conflicting results. Most cross-country studies find a weak impact of globalization on income inequality. In contrast, several longitudinal studies concerning countries taken separately or small groups of countries reveal a positive correlation between openness and the relative demand for skill and inequality. These apparently conflicting findings reflect the opposite mechanisms linked to globalisation and the differences in countries’ experiences.

Globalization and the Inequality–Unemployment Tradeoff

Over the last 20 years, advanced economies have experienced an “unemployment versus inequality” tradeoff that is critically uneven across countries. To explain this, we propose an extended HOS model in which: the factors are skilled and unskilled labor; there is a continuum of goods; the world comprises two North countries (one egalitarian and one nonegalitarian) and the South; there is no factor price equalization; globalization consists in the South cornering a growing share of world production. In the North, globalization entails an inequality–unemployment tradeoff and the adjustment to globalization is more painful for the country that was initially inequality-oriented.

Globalization and Inequality: Where Do We Stand?

Over the last thirty years, both developed and developing countries have experienced a huge globalization of their economies, which has coincided with an increase in intra-country income inequality, both within and between skill groups. This article surveys the key mechanisms of the globalization-inequality relationship. Four strands of literature are reviewed. First, the extension of the North-South HOS approach by relaxing certain simplifying assumptions makes it possible to generate most of the observed facts on trade and inter-skill group inequality, but also between unequally talented workers. Second, production segmentation and offshoring reveal several factors that increase inequality, particularly in developing countries. Third, accounting for firm heterogeneity generates intra-skill group inequality. Fourth, globalization causes changes in technologies and in institutions that can foster inequality. The mechanisms by which globalization raises inequality are thus numerous. A large part of the reviewed literature combines globalization with technological or/and institutional changes, which reconciles the three major explanations that have been given to the observed rise in inequality.

Skill Premia and Intergenerational Skill Transmission: The French Case *

In the case of France, we analyse the changes (i) in the skill premium linked to each level of education and (ii) in the impact of parents’ skill and income upon the educational attainment of their children. To this end, we build a theoretical model which is subsequently estimated. Our calculations firstly reveal (i) a critical decline in the skill premium of the Baccalaureate in relation to the lowest skill level, and (ii) an increase in the skill premia of higher education in relation to the Baccalaureate, which however is not large enough to avoid the decrease in all the skill premia relative to the lowest skill. Secondly, we find (i) a significant increase in the impact of the family backgrounds upon the individuals’ education from 1993 to 2003 which essentially derives from a higher impact of parental income upon the educational attainment, and (ii) an increase in the impact of public expenditure upon education. Consequently, if inequality has decreased among the employed population, the slowdown in intergenerational mobility could reverse this tendency in the longer term. This may however be offset by higher public educational expenditure.

Combining minimum wage and exchange rate policy to release the external constraint on growth

In this article we analyse the combination of a minimum wage and a devaluation/depreciation so as to release the external constraint on growth. The policy maker aims at achieving both balanced trade and higher growth. These may be reached by devaluating the domestic currency, which however supports traditional industries characterized by high price elasticity and low income elasticity of demand. The release of the external constraint in the short term then yields a stronger constraint in the longer term. If traditional industries are unskilled and labour‐intensive, the setting of a minimum wage distorts the specialization towards sectors with high demand growth. Devaluation/depreciation and minimum wage may thus be combined to release both the short term and longer term external constraint. We determine the condition for such a policy to be efficient. This combined policy must come with an educational policy that supports skill upgrading. It is typically tailored to ‘advanced emerging countries’ which aim at changing their specialization without slowing their growth.

Wage Inequality and Immigration: Western-Europe in the Sixties

We analyse the immigration flows to Western Europe in the sixties. We develop a theoretical model tailored to account for some of the key features of this period, i.e., trade in manufacturing that essentially involved advanced countries, the growing administration of labour markets in Western Europe and the huge inflow of low skilled immigrants from the South (less advanced countries) into Western Europe. Two propositions are subsequently derived from this model. First, the immigration flow increases with the skill premium in the country of destination. Second, for a given skill premium, immigration is an increasing function of both the host country’s working population and its relative endowment in skilled labour. The first proposition reflects a demand side effect that diverges from the result of the traditional self-selecting approach to migration, i.e., that a higher skill premium in the country of destination tends to discourage potential low-skilled migrants. Estimations implemented for a panel of four European countries (Belgium, France, Sweden and West Germany) over the period 1960-1975 corroborate to a large extent our propositions. We also find that none of the supply determinants are individually significant at equilibrium. These results confirm the hypothesis that immigration to Western Europe in the sixties was primarily demand driven.
