There is a strong correlation between the corporate interest rate spread and the unemployment rate.We make two contributions to the literature based on this observation. First, we model the mechanisms by which these financial conditions can affect unemployment in a DMP model with capital....

We bring together the theories of duality and dynamic programming. We show that the dual of a separable dynamic optimization problem can be recursively decomposed. We provide a dual version of the principle of optimality and give conditions under which the dual Bellman operator is a contraction...

The wealthy hand-to-mouth are households who hold little or no liquid wealth (e.g. cash, checking, and saving accounts), despite owning sizable amounts of illiquid assets (i.e., assets that carry a transaction cost, such as housing, large durables, or retirement accounts). This portfolio...

When compared to the early 2000's, the post financial crisis US labor market has produced a persistently higher unemployment rate relative to the level of vacancies posted by firms. In this paper we provide a quantitative general equilibrium model that explains one possible cause for this change...

This paper studies the maturity, timing and relative size of repayments for sovereign debt. Using Bloomberg bond data for emerging economies, we document that sovereigns issue debt with shorter maturity but more back-loaded repayments during downturns. To account for this pattern, we study a...

We analyze the optimal capital structure and investment strategy of banks and other financial institutions. We develop conditions under which banks optimally choose a fragile capital structure that is subject to runs. We show that when bank depositors have limited ability to commit to long-term...

The leading theories on monetary policy non-neutrality require some degree of price rigidity, which is often introduced by assuming fixed costs of price adjustment, also known as menu costs. Empirical evidence on the existence of such menu costs is scarce. Using weekly data on prices, costs and...

We construct a microfounded, dynamic version of the IS-LM-Phillips curve model by adding two elements to the money-in-the-utility-function model of Sidrauski (1967). First, real wealth enters the utility function. The resulting Euler equation describes consumption as a decreasing function of the...

International trade and the internal movement of goods and people are closely related. China – increasingly open and with massive internal migration flows – provides an ideal setting to study these interrelationships. We develop a general equilibrium model of internal and external...

We develop a dynamic nonlinear, noisy REE model of credit risk pricing un- der dispersed information that can theoretically and quantitatively account for the credit spread puzzle. The first contribution is a sharp analytical characteri- zation of the dynamic REE equilibrium and its comparative...
