In this paper, we develop a model of innovation-based growth to address the issue of skill-biased technical change over the long run. We show that innovations fluctuate endogenously from skilled to unskilled sectors, thereby generating periods of increasing and decreasing wage inequality. This...

In this paper, we develop a model of innovation-based growth to address the issue of skill-biased technical change over the long run. We show that innovations fluctuate endogenously from skill-intensive to unskilled-intensive sectors, thereby generating periods of increasing and decreasing wage...

In this paper, we argue that credit market imperfections impact not only the level of unemployment, but also its persistence. For this purpose, we first develop a theoretical model based on the equilibrium matching framework of Mortensen and Pissarides (1999) and Pissarides (2000) where we...

In this paper, I build a wage bargaining model to study the consequences of unemployment insurance and unemployment assistance on unemployment. I show that indexing the unemployment insurance benefit on the last wage earned increase the level of unemployment. I describe necessary conditions to...

We contribute to the debate on skill-biased technical change by studying the long-run dynamics of skill premia in an endogenous growth model in which technical change can be directed alternately towards different factors. We show that R&D resources tend to be directed alternately towards...

We analyze a model of 'postelection politics', in which (unlike in the more common Downsian models of 'preelection politics') politicians cannot make binding commitments prior to elections. The game begins with an incumbent politician in office, and voters adopt reelection strategies that are...

In this paper, I introduce money in the standard labor-matching model (Mortensen and Pissarides 1999, Pissarides 2000). A double coincidence problem makes Fiat Money necessary as a medium of exchange. In the long-run, a rise in the rate of money growth leads to higher inflation and higher...
