Abstract. Our work treats the relationship between inequality and technological changes. Specifically, we focus on the transmission mechanisms by which technological innovations affect the inequality in access to employment. The objective of this article is to determine the effects of the diffusion of innovations on the demand for skilled and non-skilled labor. It is focuses on the concept of technological bias and the role of inequality between skilled and unskilled workers. The empirical validation of this work is based on the technique of dynamic Panel. An estimate by the method of Arellano and Bond seems more relevant. Actually, there is a positive relationship between innovations and the demand for skilled labor but a negative relationship for unskilled labor. This result is confirmed in our sample of countries.

Keywords: Technological changes, inequality in access to employment, skill biased technological changes, complementarity between capital and skilled labor.
