Between- and within-group wage inequalities, and the advent of new technology


We present a simple model that explains two features of the dynamics of wage inequalities: between-group and within-group. Individuals are assumed to be heterogeneous in their innate abilities. With the advent of a new technology, each individual decides whether or not to acquire the skill for the new high-tech sector. The heterogeneity explains not only the between-group wage inequality but also the within-group wage inequality, which are observed in advanced countries such as the US and UK.
