This paper examines how skill-biased growth can generate economic fragmentation (income disparities) that give rise to social fragmentation (the adoption of increasingly incompatible social identities and values), which generate political fragmentation (the adoption of increasingly incompatible...

This paper sheds light on how changes in the organization of work can help to understand increasing wage inequality. We present a theoretical model in which workers with a wider span of competence (higher level of multitasking) earn a wage premium. Since abilities and opportunities to expand the...

The paper analyzes the influence of minimum wages on firms' incentive to train their employees.

We explore the far-reaching implications of low-wage subsidies on aggregate employment. Low-wage subsidies have three important effects. First, they promote employment of unskilled workers (who tend to be the ones who earn low wages). Second, by raising the payoff of unskilled work relative to...

We analyze the interaction among important institutional variables in the labor market (firing costs, minimum wages and unemployment benefits) in determining firm-provided training. We find that the institutional interactions - specifically, their degree of complementarity and substitutability -...
