How to promote R&D-based growth? Public education expenditure on scientists and engineers versus R&D subsidies

This paper compares the positive and normative implications of two alternative measures to promote R&D-based growth: R&D subsidies to firms and publicly provided education targeted to the development of science and engineering (S&E) skills. The model accounts for the specificity of S&E skills, where individuals with heterogeneous ability choose their type of education. Although intertemporal knowledge spillovers are the only R&D externality, the analysis suggests that R&D subsidies may be detrimental to both productivity growth and welfare. Moreover, they raise earnings inequality. In contrast to R&D subsidies, publicly provided education targeted to S&E skills are found to be unambiguously growth-promoting and neutral with respect to the earnings distribution.     

EARNINGS INEQUALITY, LABOUR SUPPLY AND SCHOOLING IN HUSBAND–WIFE FAMILIES

This paper describes the association between market work and earnings inequality across families over the life cycle and over calendar time with special attention to the different experiences of college‐educated and high‐school‐educated people. A concise and effective accounting framework is developed that allows for an assessment of the effect of the growing market employment of married women on family earnings inequality. Applying this framework to pseudo‐panel data from successive Current Population Surveys indicates that the increase in wives' employment has diminished the growth in family earnings inequality especially for well‐educated couples. Inferences about the level and change in earnings inequality depend on the degree of labor market attachment of the people studied especially in the case of wives.     

Factor decomposition of cross-country income inequality, 1960–1990

In this paper we present Esteban's 1994 [Esteban, J., 1994. La desigualdad interregional en Europa y en España: descripción y análisis. In: Esteban, J.M^a., Vives, X. (dirs.), Crecimiento y convergencia regional en España y en Europa, Vol. 2, Instituto de Análisis Económico] decomposition of the Theil index of inequality over per capita incomes into the (unweighted) sum of the inequality indices of (i) the productivity per employed worker, (ii) the employment rate, (iii) the active over working-age population rate, and (iv) the working-age over total population rate. Each of these factors clearly have different meanings for analysis as well as for policy. We apply this factoral decomposition to a set of 120 countries. We also contrast the empirical findings with the results obtained for the 23 OECD countries. [OECD, Labour Force Statistics, Several issues, Paris].     

DISTRIBUTIONS OF REAL INCOME: WITHIN COUNTRIES AND BY WORLD INCOME CLASSES

Income and expenditure data from 14 countries (representing one-third of the world's population), mostly from the 1970s, are used to construct national income distributions and , after normalizing by purchasing power parities, to construct a "world" distribution of real income. The density of real-income equivalent groups (socio-economic classes) across countries is measured for the "affluent," the "well-off," and the "poor." In comparison with earlier studies, most national distributions of income seem to have been improving, the numbers of those in poverty (based on real income) are lower, and, most important (and disturbing for some) is that the "affluent" class (and those above "middle class" income levels) has (prematurely) swelled in a number of developing countries.     

A Gini decomposition analysis of inequality in the Czech and Slovak Republics during the transition1

Disposable income inequality, as measured by the Gini coefficient and using the Family Budget Survey data, increased very little, and by a similar amount, from 1989 to 1993 in the Czech Republic and Slovakia. This surprising result is examined with an analysis of changes in the channels of redistribution and Gini decomposition. We find that the sizeable increase in overall inequality due to changes in the wage earnings component is mitigated by changes in the tax and transfer components in both republics. As for the relative effects of government policies, changes in the transfer component contributed more than changes in the tax component to lowering the growth of inequality in the Czech Republic, while the reverse was true for Slovakia.     

Agro-Manufactured Export Prices, Wages and Unemployment

This article estimates the impacts of world agricultural trade liberalization on wages and unemployment in Argentina in the presence of individual labor supply responses and adjustment costs in labor demand. After a 10% increase in agro-manufactured export prices, I find that: ( a ) the employment probability would increase by 1.36 percentage points, matched by a decline in the unemployment probability of 0.75 percentage points and an increase in labor market participation of 0.61 percentage points; ( b ) the unemployment rate would decline by 1.23 percentage points; ( c ) expected wages would increase by 10.3%, mostly due to higher employment probabilities.     

Decomposing Income Inequality and Policy Implications in Rural China

Using village data from samples covering 6 provinces,36 counties and 216 townships,the income inequalities within and between townships in rural China are assessed. The Theil index and the mean logarithmic deviation methods enable us to test income inequality at the township level,and to decompose it into intra-regional and inter-regional at county and provincial levels. In the present paper,we also decompose income inequalities between and within the nationally designated poor counties (NDPC). The results show that approximately two-thirds of the income inequality in rural China would be eliminated if measures and policies were targeted at the county level. This study also confirms the rationale that China's poverty alleviation strategy of focusing on poor counties based on the inequalities between NDPC and non-NDPC accounts for the most inter-province inequality.     

An Application of an Integrated Transport Network– Multiregional CGE Model: a Framework for the Economic Analysis of Highway Projects

This paper develops a framework for the economic analysis of highway projects that is then used to estimate the dynamic economic effects of a highway project on the economic growth and the regional disparity in Korea. The framework is composed of a transport model and a multiregional Computable General Equilibrium (CGE) model. The transport model measures a change in interregional shortest distances and the accessibility due to the highway project. The CGE model estimates the spatial economic effects of the project on GDP, the price, exports, and the regional distribution of wages and population. The simulation allows policy makers to determine which highway development deserves the priority for investment, based on consideration of economic growth and regional economic equity in the long run. The simulation found that all the highway projects have positive effects on GDP and export growth as well as regional equity in terms of wage and population.
