This paper studies an urban growth model where learning through personal contacts could be more effective in a denser locale, whereas the effectiveness of learning through impersonal means of communications depends principally on the technology of communications rather than on the locale in...

Credit supply and demand changes are mostly unobserved, thus identifying completely the transmission of monetary policy through the credit channel is unfeasible. Bank lending surveys by central banks, however, contain reliable quarterly information on changes in loan conditions due to bank, firm...

This paper studies corporate debt structure over the business cycle and its implications for aggregate macroeconomic dynamics. We develop a tractable macro-finance model featuring debt heterogeneity with both secured and unsecured debt. Unlike secured debt, unsecured debt gives the lenders no...

Investment booms and asset "bubbles" are often the consequence of heavily leveraged borrowing and speculations of persistent growth in asset demand. We show theoretically that dynamic interactions between elastic credit supply (due to leveraged borrowing) and persistent credit demand (due to...

Do fluctuations of the labor wedge, defined as the gap between the firm's marginal product of labor (MPN) and the household's marginal rate of substitution (MRS), reflect fluctuations of the gap between the MPN and the real wage or fluctuations of the gap between the real wage and the MRS? For...

Counter-cyclical fluctuations in the price of investment in consumption units are often attributed to investment-specific technology shocks. This paper looks at an additional source for such fluctuations: sector-specific markup variations, the idea being that pro-cyclical competition and the...

This paper develops a monetary model with taxes to account for the time-varying effects of energy shocks on output and hours worked in post-World War II U.S. data. In our model, the real effects of an energy shock are amplified when the monetary authority responds to that shock by changing its...

The Chilean economy experienced a decade of sustained growth in aggregate output and productivity after the 1982 financial crisis. This paper analyzes the role of allocative efficiency on total factor productivity (TFP) in the manufacturing sector by applying the methodology of Hsieh and Klenow...

This paper provides a rational expectations equilibrium framework to organize the following observations about the U.S. housing market from 1975 to 2007: (i) housing occupancy patterns were approximately constant, (ii) rents were stable, and (iii) house prices appreciated considerably in the...

We present a model of long-duration collateralized debt with risk of default. Applied to the housing market, it can match the homeownership rate, the average foreclosure rate, and the lower tail of the distribution of home-equity ratios across homeowners prior to the recent crisis. We stress the...
