This paper analyzes, from a theoretical perspective, the role of the financial system to promote growth and macroeconomic stability. It also endogenously explains the performance of the financial systems as a consequence of industrial (or sectoral) diversification. In the model, the productive...

We study the cyclical implications of credit market imperfections in a calibrated dynamic, stochastic general equilibrium model wherein firms face persistent shocks to aggregate and individual productivity. In our model economy, optimal capital reallocation is distorted by two frictions:...

This paper adds a highly-leveraged financial sector to the Ramsey model of economic growth and shows that this causes the economy to behave in a highly volatile manner: doing this strongly augments the macroeconomic effects of aggregate productivity shocks. Our model is built on the financial...

We study housing and debt in a quantitative general equilibrium model. In the cross-section, the model matches the wealth distribution, the age pro?les of homeownership and mortgage debt, and the frequency of housing adjustment. In the time-series, the model matches the procyclicality and...

This paper presents the business cycle model that Trygve Haavelmo developed as part of his research program in macroeconomic and monetary theory. Driven by a mismatch between the marginal return to capital and the rate of return required by capital owners, this model generates endogenous cycles....

Many economists believe that the stock market plays an important role in efficiently allocating capital to its most productive uses. This standard story of the stock market was called into question by events in the late 1990s, when some observers believed that stock market overvaluation – or a...

This paper studies the macroeconomic implications of firms' investment composition choices in the presence of credit constraints. Following a negative and persistent aggregate productivity shock, firms shift into short-term investments because they produce more pledgeable output and because they...

Credit spreads are large, volatile, and countercyclical, and recent empirical work suggests that risk premia, not expected credit losses, are responsible for these features. Building on the idea that corporate debt, while fairly safe in ordinary recessions, is exposed to economic depressions,...

This paper develops an RBC model where banks use short-term deposits to provide firms with long-term credit. The demand for long-term credit arises because firms borrow in order to finance their capital stock which they only adjust at infrequent intervals. We show that maturity transformation in...

This paper investigates the effect of changes in the retention ratio, profit share, interest rate, and natural rate of growth on the rate of capital accumulation and the financial structure of firms by using a Kaleckian growth model with labor supply constraints. We show that if the economy...
