Catastrophic Risk and Credit Markets

We provide a model of the effects of catastrophic risk on real estate financing and prices and demonstrate that insurance market imperfections can restrict the supply of credit for catastrophe-susceptible properties. Using unique micro-level data, we find that earthquake risk decreased commercial real estate bank loan provision by 22% in California properties in the 1990s, with more severe effects in African–American neighborhoods. We show that the 1994 Northridge earthquake had only a short-term disruptive effect. Our basic findings are confirmed for hurricane risk, and our model and empirical work have implications for terrorism and political perils.     

Changing Monetary Policy Rules, Learning, and Real Exchange Rate Dynamics

When the exchange rate is priced by uncovered interest parity and central banks set nominal interest rates according to a reaction function such as the Taylor rule, the real exchange rate will be determined by expected inflation and the output gap or the unemployment gap of the home and foreign countries. This paper examines the implications of these Taylor rule fundamentals for real exchange rate determination. Because the true parameters in central bank policy rules are unknown to the public and change over time, the model is presented in the context of a least squares learning environment. This simple learning model captures the volatility and the major swings in the real deutschemark/euro–dollar exchange rate from 1976 to 2007.     

Bank Loan Supply, Lender Choice, and Corporate Capital Structure

This paper explores the relevance of capital market supply frictions for corporate capital structure decisions. To identify this relationship, I study the effect on firms' financial structures of two changes in bank funding constraints: the 1961 emergence of the market for certificates of deposit, and the 1966 Credit Crunch. Following an expansion (contraction) in the availability of bank loans, leverage ratios of bank-dependent firms significantly increase (decrease) relative to firms with bond market access. Concurrent changes in the composition of financing sources lend further support to the role of credit supply and debt market segmentation in capital structure choice.     

Constructing Asset Pricing Models With Specific Factor Loadings

We demonstrate how one can build pricing formulae in which factors other than beta may be viewed as determinants of asset returns. This is important conceptually as it demonstrates how the additional factors can compensate for a market portfolio proxy that is mis‐specified, and also shows how such a pricing model can be specified ex ante. The procedure is implemented by first selecting an ‘orthogonal’ portfolio which falls on the mean‐variance efficient frontier computed from the empirical average returns, variances and covariances on the equity securities of a large sample of firms. One then determines the inefficient index portfolio which leads to a vector of betas that when multiplied by the average return on the orthogonal portfolio, and which when subtracted from the vector of average returns for the firms comprising the sample, yields an error vector that is equal to the vector of numerical values for the variables that are to form the basis of the asset pricing formula. There will then be a perfect linear relationship between the vector of average returns for the firms comprising the sample, the vector of betas based on the inefficient index portfolio and such other factors that are deemed to be important in the asset pricing process. We illustrate computational procedures using a numerical example based on the quality of information contained in published corporate financial statements.     

Inflation and Unit Labor Cost

We study two decompositions of inflation, π, motivated by the standard New Keynesian pricing equation of Gali, Gertler, and Sbordone. The first uses four components: lagged π, expected future π, real unit labor cost (ψ), and a residual. The second uses two components: fundamental inflation (discounted expected future ψ) and a residual. We find large low‐frequency differences between actual and fundamental inflation. From 1999 to 2011 fundamental inflation fell by more than 15 percentage points, while actual inflation changed little. We discuss this discrepancy in terms of the data (a large drop in labor's share of income) and through the lens of a canonical structural model.
