A Binomial Analysis of the Decision to Innovate in a Sample of Private Tunisian Firms

By Adel Tlili, Ali Chkir

This article studies the impact of determinants and constraints on the innovation decision in private firms in Tunisia over the period 2002–2004. By using a binomial logit model, we conclude that this decision depends essentially on two internal determinants (the firm size and the existence of internal R&D activity) as well as two external determinants (the cooperation with the public sector and the cooperation achieved with the private one). We also conclude that there is no significant effect of constraints on this decision.
