- Abstract
- (en) This dissertation tries to gain insight on the possible impact of information and communication technologies (ICT) in economic and social relationships. Can we really talk about a revolution?. It is probably too early to conclude so. In any case, the social impact of ICT seems evident: the daily life of most individuals, firms and public administrations in developed countries is nowadays linked to new technologies. Regarding their economic impact, this dissertation has investigated the role played by ICT in explaining some of the stylized facts that have characterized European economies over the last 25 years. Using Spanish data, chapter 1 shows that capital accumulation, and especially ICT introduction over the last 20 years, has led firms to internally reorganize themselves. Furthermore, the implemented organizational changes have been skill-biased and have, thus, stimulated the demand for high-skilled workers. Based on these results, in chapter 2 an inter-temporal general equilibrium model endogenizing the capital-skill complementarity relationship has been developed. The model distinguishes between two types of jobs, complex and simple, and two types of workers, high- and low-skilled. Complex jobs can only be occupied by high-skilled while simple jobs can be filled by both, high- and low-skilled workers. High-skilled workers in simple jobs continue to search for a job in the complex segment (on-the-job search). Matching processes are represented by matching functions à la Pissarides. Workers search intensities are endogenous. Calibrated on the Belgian economy, the model is able to reproduce the observed increase in unemployment rates and relative wage rigidity. Chapter 3 extends this theoretical setup to an endogenous growth framework, where embodied and disembodied technological progress are differentiated and endogenized through a learning-by-doing process based on capital accumulation. The new model also provides a realistic representation of the labor market and it considers growth issues. Chapter 4 analyzes the effects of technological and organizational changes within firms on the turnover of different professional categories. Empirical results, based on a unique French data set, suggest that ICT introduction increases labor flows of manual workers and employees, whereas most of the new workplace organizational practices raise the turnover of managers.
