We study the otherwise standard growth model with money except endogenous time preferences determined by resources pent on imagining future pleasures along the line of Becker and Mulligan (1997). Money plays a role in transactions via the cash-in-advance constraint.The resulting steady-state...

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...

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...

This paper studies the role of an endogenous time preference on the relationship between inflation and growth in the long run in both the money-in-utility-function (MIUF) and transaction costs (TC) models. We establish a qualitative equivalence between the two models in a setup without a...

In order to explain multiple growth regimes, one of the working hypotheses is based on initial conditions. Using a standard optimal growth with the status effect represented by wealth a la Friedman (1953), this paper obtains multiple growth regimes based on initial conditions without reliance on...
