Impact of the adoption of information and communication technologies on firm efficiency in the Tunisian manufacturing sector

This paper aims at measuring the impact of information and communication technology use on the efficiency of the Tunisian manufacturing sector at the firm level within a simple theoretical framework. We are using a firm-level panel data for the manufacturing sector in Tunisia to investigate whether adoption of ICT influences efficiency in factor use. The analysis is conducted through the use of a parametric method to measure technical efficiency. We estimate a stochastic production frontier and the relationship aims to explain technical efficiency differentials in a single stage as suggested by Battese and Coelli [Battesse, G.E, Coelli, T.J. (1995). A model for technical inefficiency in a stochastic frontier production function for panel data. Empirical Economics, 20, 325–332].The results have confirmed the presence of positive returns to ICT capital. We have found that the impact of ICT on efficiency is strong. Our results also suggest that it is important to carefully control for human capital related characteristics of employment when studying the effect of ICT. The evidence shows that achieving benefits from investment in ICT requires complementary investments and changes in human capital. This means that the combined use of ICT and human capital in a firm would enhance its efficiency beyond the direct effects of these factors taken alone.     

Rethinking the Links between Human Relationships and Economic Efficiency Using Local Institutions: The Case of Two Emerging Economies

Emerging countries around the world have been growing fast over the last thirty years, with most of these countries basing their economic development on a state capitalism. Within these countries, there is a concentration of wealth in the hands of a few people. This fact confirms the analysis of Thorstein Veblen (1898 Veblen, Thorstein. “Why Is Economics Not an Evolutionary Sciences?” Quarterly Journal of Economics 12, 2 (1898): 373–397.[Crossref] , [Google Scholar]) who shows the gap that exists between the vested interest of the rich and the unmet needs of the poor. The world happiness report (Helliwell, Layard and Sachs 2016 Helliwell, John F., Richard Layard and Jeffrey Sachs, eds. World Happiness Report 2016. World Happiness, 2016. Available at http://worldhappiness.report/wp-content/uploads/sites/2/2016/03/HR-V1_web.pdf. Accessed December 1, 2016. [Google Scholar]) also shows for the emerging economies a gap between the world rank in economic growth and in wellbeing. I propose a new paradigm of development for two emerging economies, Brazil and South Africa, by putting human development in the center of economic development and by using different approaches in economics and psychology. My analysis links the theories of Carl Shapiro and Joseph E. Stiglitz regarding “efficiency wages” (1984 Shapiro, Carl and Joseph E. Stiglitz. “Equilibrium Unemployment as Worker Disciplines Devices.” American Economic Review 74, 3 (1984): 433–444.[Web of Science ®] , [Google Scholar]) with the complexity approach (Le Moigne 1995 Le Moigne, Jean-Louis. La modélisation des systèmes complexes. Paris, France: Dunod, 1995. [Google Scholar]). This approach combines the results of positive psychology (Kahneman 2011 Kahneman, Daniel. Thinking, Fast and Slow. London, UK: Penguin, 2011. [Google Scholar]) with the role of local institutions for improving the economic development of emerging economies (Deaton 2016 Deaton, Angus. La grande évasion: Santé, richesse et origine des inégalités. Paris, France: PUF, [2015] 2016. [Google Scholar]). In the first section of the article, I examine definitions of economic and human wealth. In the second section, I analyze the gaps that exist between the standard-of-living ranking and the wellbeing ranking for both Brazil and South Africa in order to present meso-happiness indexes linking the micro- and macro-levels of human wealth. In the last section, I analyze the way local institutions in Brazil and South Africa could create dynamic links for these countries’ efficient functioning in the world economy.     

Manufacturing Wage Differentials and Employment in Some Scandinavian Countries, the U.S. and the U.K.: An Analysis of Variance Approach

This paper presents some empirical evidence on the factors determining changes in wage differentials between skilled and unskilled workers and in their employment. An ``analysis of variance' (ANOVA) model is estimated using UN data for five OECD countries in order to assess the relative importance of industry-specific, country-specific and international shocks (as well as interactions between industry and country effects). It is found that both international shocks and national policies affect wage differentials over the whole sample, whilst skill-biased technical change (SBTC) was a significant factor in the seventies. Employment responds mainly to international shocks, although national policies and SBTC were important determinants in the seventies and eighties respectively. Some of the results are found to be sensitive to the technology level of the industries considered.     

The Endogeneity of Optimum Currency Areas Criteria: Some Evidence from the European Union and Portugal

Observing the statistical relationship between business cycles correlation and trade intensity in the European Union, euro zone, and the Portuguese economy, we conclude that there is, in general, a positive effect that supports the endogeneity argument proposed by Frankel and Rose (The Economic Journal 108(449):pp. 1009–1025, 1998). However, if we analyse this relationship in sub-periods – 1967–1975, 1976–1985, 1986–1992, and 1993–2003 – we conclude that endogeneity hypothesis just hold in the first two, although the correlations are increasing. This could mean that, after the Single European Act in 1986, other forces beyond trade are contributing to business cycle synchronization. The Portuguese business cycle correlation with the European Union and the Euro zone had also increased in these four decades, despite the fact that endogeneity hypothesis is at a 90 percent confidence level. We also analyse the bilateral relationships between the Portuguese economy and the other European Union countries and find that the endogeneity is confirmed in just four cases: Spain, Ireland, Netherlands, and UK.
