The past 30 years have witnessed lower employment rates and lower hours worked per worker, and thus lower hours worked per person, in Europe relative to the US. European countries have more regulated labor market then the US. This paper envisages the role the labor market regulation plays on the...

Labor supply in Europe was declined by about 30% relative to the US over the past 3 decades. The decline comes from hours per worker and employment. This paper studies a matching model and the effects of labor taxes and unemployment benefits. Labor taxes decrease hours and employment, with...

Labor taxes and unemployment compensation were blamed for causing relative declines in labor supply in the EU to the US in the past decades. We propose a model with an endogenous labor force and compare with the model with an exogenous labor force. Because of discouraging the labor force, labor...

Using a public finance approach, this study investigates welfare costs between seignorage and consumption taxes in a standard growth model. One of these two taxes is used to finance exogenous public spending to balance the government budget. The steady-state welfare cost of consumption taxes is...

Empirical studies often find significant and positive R&D spillovers across firms. In this note, we incorporate this spillover effect into a scale-invariant quality-ladder model. We find that the modified model features multiple steady states (i) a high-R&D steady state, (ii) a low-R&D steady...

This paper develops a dynamic general-equilibrium model with production to examine the inter-relationships between the real and the financial sectors with and without credit market imperfections. Due to the moral hazard problem, borrowers may take the money and run while lenders may ration...

In a second-best optimal growth setup with only factor taxes as available instruments, is it optimal to fully replace capital by labor income taxation? The answer is generally positive based on Chamley, Judd, Lucas, and many follow-up studies. In the present paper, we revisit this important tax...
