Do inter-sectoral flows of services matter for productivity growth? an input/output analysis of OECD countries

This article investigates the impact of technology-intensive services sectors on direct and indirect labour coefficients in a sample of OECD countries. We find that both domestic and imported services contribute to increase productivity. We also find that different service industries (transport, communication, financial, and business services) have a different impact on technological change in non-service sectors classified according to the Pavitt taxonomy.     

A structural VAR approach on labour taxation policies

This paper presents a Structural VAR analysis on the employment and output effects of labour tax policies in six European countries for the period 1974–1997. By considering impulse response functions, it turns out that, on average, a shock to the total personal income tax revenues is positively correlated to employment, whereas there is mixed evidence on the output effect. Moreover, the quantitative impact of these effects, especially those related to the output, appears to be quite small. However, by introducing explicitly four labour tax parameters (namely the marginal and average tax rates for the personal income tax and the payroll tax), it turns out that these effects are not negligible after all: for some countries it is possible to conceive labour taxes as policy instruments favouring more employment and a better economic performance. However, the empirical support on the sign of the output and employment effects is mixed, suggesting that the same domestic fiscal policy does not produce the same impact in all the European countries.     

Gini’s transvariation analysis: an application on financial crises in developing countries

The damage and the recurrence of financial crises have increased the concern of investors and policymakers on one hand and the interest of macroeconomists on the other. This paper presents an original non parametric methodology, whose aim is to give a very intuitive and rigorous method for variable selection in order to analyse financial crises. Transvariation analysis compares the distributions of two different groups of countries (sound and distressed) with respect to a single macroeconomic variable and selects the indicators on the basis of a low transvariation probability index. The current account deficit to GDP ratio, differently from other studies on financial crises, seems to be a suitable variable in discriminating distressed countries from sound ones, and the case of Argentina and Turkey confirms this finding.

Employment Patterns of Husbands and Wives and Family Income Distribution in Italy (1977–98)

The pattern of employment among men and women has changed remarkably over the past decades. The growth in the participation in the labor market of women with high-income husbands has heightened concerns that wives' earnings may increase income inequality among married couples, especially in countries like Italy, the U.K., and the U.S., where more noticeable growth of income inequality during the past decade has accompanied changes in employment levels. In this paper we attempt to measure the impact of the changes of women and men's employment patterns on the distribution of income among Italian households, by considering regional differences, using micro data from the Historical Archive of the Bank of Italy Survey of Household Income and Wealth (SHIW) for the period 1977–98. Our results indicate that total income distribution would have been more unequal without women's labor income.

When the difference makes a difference – the regional embeddedness of entrepreneurship

Abstract

Regional determinants of new firm formation are of interest to researchers and policymakers. In the analysis of new firm formation, most studies use econometric approaches that mask intra-unit variations, not recognizing counterbalancing and dilution effects as a result. Recent advances in spatial statistics such as Geographically Weighted Regression (GWR) take local variations into account. However, these approaches operate only on a bivariate level, making it impossible to detect the homogenous parts of the area under examination with regard to a number of relationships between new firm formation and its determinants. Based on a sample of 412 German regions, we apply GWR and subsequent graph-partitioning clustering to identify multi-relationally homogeneous sub-areas. Being that the results suggest a four-cluster solution, ‘one size fits all’ policies and premature unit zoning can be called into question.     

Creditor protection,judicial enforcement and credit access

We investigate the impact of the legal system on whether firms obtain the credit they apply for or not. Data comprise unique information provided directly by 48,590 firms from 11 European countries. We look at the strength of creditor protection, the strength of property rights, the time taken to resolve a dispute, the dispute resolution process’s costs and the number of procedures the plaintiff faces using data provided by the World Bank and the Heritage Foundation. The results suggest that the more efficient the judicial enforcement system is, and the higher the creditor protection is, the lower the probability that the firms are partially or totally denied credit. Our results are robust to selection bias (Heckman selection) as well as different controls and different estimation techniques. We find that these variables have considerable economic impact: the probability of obtaining credit is up to 40% higher in countries with more robust legal systems.     

Modelling Sustainable Consumption. From Theoretical Concepts to Policy Guidelines

Changes in consumption processes have been recognised as important steps towards sustainable development. The aim of this paper is to give an overview of research on sustainable consumption and to sketch new approaches in economic modelling ofsustainable consumption. A special focus is given to the relationship between stocks and flows as well as consumer services as being welfare relevant. From that three different steps of modelling are proposed, where the links between material goods demand and consumer services demand as well as the stock-flow relationship can be made explicit.
