We develop a variation of the macroeconomic model of banking in Gertler and Kiyotaki (2011) that allows for household liquidity risks and bank runs as in Diamond and Dybvig (1983). As in Gertler and Kiyotaki, because bank net worth fluctuates with aggregate production, the spread in the expected...

This paper develops a dynamic general equilibrium model that tries to reconcile the observation that aggregate movements of exports and imports are "disconnected" from real exchange rate movements, while firm-level exports co-move significantly with the real exchange rate. Firms are...

can be large at zero nominal interest rates. We show model simulations in which these policy interventions prevented a repeat of the Great Depression in 2008-2009.

We develop a framework for modelling differences in liquidity across assets in order to examine the interactions between asset prices, liquidity premia and aggregate activity. In so doing, we want to find out what role government policy might have through open market operations that change the...

This paper is a quantitatively-oriented theoretical study into the interaction between housing prices, aggregate production, and household behaviour over a lifetime. We develop an overlapping generations model of a production economy in which land and capital are combined into residential and...

We develop a model of gross job and worker flows and use it to study how the wages and employment status of individual workers evolve over time and how they are affected by aggregate labor market conditions. We also examine the effects that labor market institutions and public policy have on the...

We develop a model in which innovations in an economy's growth potential are an important driving force of the business cycle. The framework shares the emphasis of the recent "new shock" literature on revisions of beliefs about the future as a source of fluctuations, but differs by tieing these...

We develop and estimate a medium scale macroeconomic model that allows for unemployment and staggered nominal wage contracting. In contrast to most existing quantitative models, the employment and hours of existing workers are efficient. Wage rigidity, however, affects the hiring of new workers....

We introduce long-term government bonds along with private credit instruments into a monetary DSGE model with financial intermediaries that face endogenously determined balance sheet constraints. We use it to compare the effects of large-scale purchases of private and government assets after a...

We explore the implications of current account adjustment for monetary policy within a simple two-country DSGE model. Our framework nests Obstfeld and Rogoff’s (2005) static model of exchange rate responsiveness to current account reversals. It extends this approach by endogenizing the dynamic...
