In this paper, I study the existence and uniqueness of recursive equilibria in economies with aggregate and idiosyncratic risk. Rather than relying on compactness to establish existence, I exploit the monotonicity property of the equilibrium model and rely on arguments from convex analysis. This...

In the aftermath of the financial crisis of 2008, there is increased concern about the potentially catastrophic pension default risk, which results in significant decreases in pension benefits. In order to address the challenge of annuity income uncertainty, I propose a dynamic annuitization...

We develop a retirement model with long-run income risk in which the wealth threshold for retirement is shown to be a function of the extent of the long-run income risk. By devising a new numerical algorithm, we solve the two-dimensional retirement problem. The two-dimensional retirement...

In this paper, we develop a new dynamic programming approach for solving an optimal retirement model in a two-dimensional incomplete market, which is induced by forced unemployment risk and borrowing constraints. We show that the two dimensions jointly affect an individual's optimal consumption,...

I study optimal consumption and investment for retirement in an economic environment where an individual has retirement flexibility and borrowing constraints. I show that Friedman's (1957) permanent income hypothesis (PIH) is generalized with retirement and constrained borrowing against future...

This paper derives the general equilibrium effects of rational inattention (or RI; Sims 2003, 010) in a model of incomplete income insurance (Huggett 1993, Wang 2003). We first show that, under the assumption of CARA utility with Gaussian shocks, the permanent income hypothesis (PIH) arises in...

This paper derives the general equilibrium effects of rational inattention (or RI; Sims 2003, 2010) in a model of incomplete income insurance (Huggett 1993, Wang 2003). We show that, under the assumption of CARA utility with Gaussian shocks, the permanent income hypothesis (PIH) arises in steady...

​We study the impact of financing constraints on investment and output dynamics, in a continuous time setting with output a linear function of capital. Decline of net worth reduces investment and, if firms can rent capital to unconstrained outside investors, can create a 'net worth trap' with...

This paper proposes a method for integrating individual effective tax rates and marginal tax rates computed from a microsimulation (partial equilibrium) model of tax policy with a dynamic general equilibrium (DGE) model of tax policy that can provide macroeconomic analysis or dynamic scores of...

We solve the optimal consumption and investment problem in an incomplete market, where borrowing constraints and insurer default risk are considered jointly. We derive in closed-form the optimal consumption and investment strategies. We find two main results with quantitative analysis. On the...
