I study the asset pricing implications and the efficiency of a tractable dynamic stochastic general equilibrium model with heterogeneous agents and incomplete markets along the lines of Krebs [Krebs, T., 2003. Human Capital Risk and Economic Growth. Quarterly Journal of Economics 118(2),...

Conditional on education and experience, the distribution of personal labor income appears to be double Pareto, a distribution that obeys the power law in both the upper and lower tails. In particular, the error term of the classical Mincer equation appears to be Laplace, or double exponential....

The size distributions of many economic variables seem to obey the double power law, that is, the power law holds in both the upper and the lower tails. I explain this emergence of the double power law—which has important economic, econometric, and social implications—using a tractable...

In numerically implementing the optimization of an expected value in many economic models, it is often necessary to approximate a given continuous probability distribution by a discrete distribution. We propose an approximation method based on the principle of maximum entropy and minimum...

This paper investigates the relationship between bubbles and government bailouts. Contrary to the previous literature about bailouts, it shows that bailouts for bursting bubbles may positively influence ex-ante production efficiency and relax the existence condition of stochastic bubbles. The...

This paper investigates theoretically how financial development affects the magnitude of financial amplification. Financial development yields two competing effects, balance sheet effects and shock cushioning effects. Depending on which of these forces dominates, we find that financial...

This paper analyzes the effects of bubbles in an in.nitely-lived agent model of endogenous growth with .nancial frictions and heterogeneous agents. We provide a complete characterization on the relationship between .nancial frictions and the existence of bubbles. Our model predicts that if the...

This paper analyzes the effects of bubbles in an infitely-lived agent model of endogenous growth with financial frictions and heterogeneous agents. We provide a complete characterization on the relationship between financial frictions and the existence of bubbles. Our model predicts that if the...

This paper investigates the relationship between bubbles and government bailouts. It shows that bailouts for bursting bubbles may positively influence ex-ante production efficiency and relax the existence condition of stochastic bubbles. The level of bailouts has a non-monotonic relationship...

We examine the effect of asset price bubbles in the Kiyotaki-Moore model. We show that the dynamic interactions between bubble-asset price, land price, and output generate powerful bubbly dynamics. The boom-bust cycles in bubble-asset price cause boom-crash cycles in the land market...
