The distributions of wealth in the US and many other countries are strikingly concentrated on the top and skewed to the right. To explain the income and wealth inequality, we provide a tractable heterogeneous-agent model with incomplete markets in continuous time. We separate illiquid capital...

We develop a model of self-fulfilling default cycles with demand externality a la Dixit- Stiglitz to explain the recurrent clustered defaults observed in the data. The literature reports that observable fundamental factors alone are insufficient to explain the cluster. A decline in aggregate...

We show that in Heterogeneous-Agent New-Keynesian (HANK) economies with countercyclical risk the natural interest rate is endogenous and co-moves with output, leaving the economy susceptible to self-fulfilling fluctuations. Unlike in Representative-Agent New-Keynesian models, the Taylor...

A growing empirical and theoretical literature argues in favor of specifying monetary policy in the form of Taylor-type interest rate feedback rules. That is, rules whereby the nominal interest rate is set as an increasing function of inflation with a slope greater than one around an intended...

When monetary policy is subject to regime switches conditions for determinacy become more complex. Davig and Leeper (2007) and Farmer, Waggoner and Zha (2009a) have studied such conditons. Using some new results from stochastic processes, we characterize the moments of the stationary...

We generalize recent results of Bassetto and Benhabib (2006) and Straub and Werning (2018) in a neo-classical model with endogenous labor-leisure choice where all agents are allowed to save and accumulate capital. We provide a sufficient condition under which optimal redistributive capital taxes...

Uncertainty in both financial markets and the real economy rises sharply during recessions. We develop a model of informational interdependence between financial markets and the real economy, linking uncertainty to information production and aggregate economic activities. We argue that there...

Even if an asset has no fundamental uncertainty with a constant dividend process, a stochastic sentiment-driven equilibrium for the asset price exists besides the well-known fundamental equilibrium. Our paper constructs such sentiment-driven equilibria under general utility functions within an...

We study the dynamics of the distribution of overlapping generation economy with finitely lived agents and inter-generational transmission of wealth. Financial markets are incomplete, exposing agents to both labor income and capital income risk. We show that the stationary wealth distribution is...

We present a mechanism to analytically generate a double Pareto distribution of wealth in a continuous time OLG model with optimizing agents who have bequest motives, are subject to stochastic returns on capital and have uncertain lifespans. We disentangle, roughly, the contribution of...
