Empirical evidence shows that entrepreneurs on average do not earn more than paid employees in terms of the net present value (NPV). One natural question is what makes the entrepreneurs to stay in business. To address this question, we propose a continuous time real options model in which an...

We consider the CUSUM of squares test in a linear regression model with general mixing assumptions on the regressors and the errors. We derive its limit distribution and show how it depends on the nature of the error process. We suggest a corrected version that has a limit distribution free of...

This paper studies the effects of heterogeneity in planning propensity on wealth inequality and asset prices. I consider an economy populated by attentive and inattentive agents. Attentive agents plan their consumption period by period, while inattentive agents plan every other period....

This paper studies the effects of heterogeneity in planning propensity on wealth inequality and asset prices. I consider an economy populated by "attentive" and "inattentive" agents. Attentive agents plan their consumption period by period, while inattentive agents plan every other period....

We study how risk aversion affects precautionary savings when considering monotone recursive Kreps-Porteus preferences. In a general infinite-horizon setting, we prove that risk aversion unambiguously increases precautionary savings. The result is derived without specifying income uncertainty,...

I propose an intertemporal precautionary-saving model in which the agent's labor income is subject to both permanent and transitory shocks. However, he only observes his total income, not individual components. I show that partial observability of individual components of income gives rise to...

This paper studies the effects of heterogeneity in planning propensity on wealth inequality and asset prices. I consider an economy populated by "attentive" and "inattentive" agents. Attentive agents plan their consumption period by period, while inattentive agents plan every other period....

We show that volatility of household consumption, after accounting for predictable variation arising from movements in real interest rates, preferences and income shocks, increased between 1970 and 2002. For single parent households, and households headed by nonwhite or poorly educated...

In this paper we study the implications of random discount rates of future generations for saving behavior and capital holdings in steady-state competitive equilibrium. We examine conditions under which this randomness is sufficient for households other than the most patient to save, thus...

We study whether the increased income uncertainty in the US over the last quarter-century had a negative impact on household welfare by looking at variability of household consumption growth. We are particularly interested in understanding the effect of greater uncertainty on the liquidity...
