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...

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...

We develop a model of state-dependent pricing that we can log-linearize and compare to the standard Calvo model. In one extreme case, money is neutral with state-dependent pricing even though the probability of price adjustment is constant as in the Calvo model. We use this example to illustrate...
