Usage de l'Internet et investissement en capital social

<marquage typemarq="gras"/> This paper aims to understand the impact of the Internet on social capital. Does the Internet usage influence the investments in social networks? First, we theoretically address this question with a micro-economic model of social capital. Second, thanks to Luxembourg data, we evaluate the determinants of the investments in social capital via the Internet. The results show a complementarity between the online investments and the offline investments (measured by the belonging to some associations or formal organizations), except for individuals who have had professional or personal mobility and who tend to intensively use the Internet to invest in social capital.
