The Effect of Business Risk on Corporate Capital Structure: Theory and Evidence

Under corporate and personal taxation, we demonstrate that the relation between optimal debt level and business risk is roughly U-shaped. This result follows from the fact that the tax liability is an option portfolio that is long in the corporate tax option and short in the personal tax option. Therefore, the net effect of a change in business risk on the optimal debt level depends upon the relative magnitudes of the resultant marginal changes in the values of these two options. Results of empirical tests offer support for the predicted U-shaped relationship.     

Securitization and Bank Performance

Using predominantly precrisis U.S. commercial bank data, this paper employs a propensity score matching approach to analyze whether individual banks did improve their performance through securitization. On average, our results show that securitizing banks tend to be more profitable institutions, with higher credit risk exposure. Despite a more diversified funding structure, they face higher funding costs. We also find that securitizing banks tend to hold larger and less diversified loan portfolios, have less liquidity, and hold less capital. However, our analysis does not provide evidence to suggest that securitization had an impact upon bank performance.     

CO‐MOVEMENT OF AUSTRALIAN STATE BUSINESS CYCLES*

We use a variety of techniques to examine the nature and degree of co‐movement among Australian state business cycles. Consistent with the results of Dixon and Shepherd (2001 ), we find that these cycles move quite closely together, with particularly strong links between the cycles of the larger states. We then seek to understand the causes of this co‐movement by using an unobserved components model to distinguish between various shocks and their transmission. Our model implies that the major source of this co‐movement in state activity is the commonality of shocks affecting state cycles. In contrast, spillovers of region‐specific shocks appear to play only a minor role in creating co‐movement, though region‐specific shocks themselves have a moderate influence on cyclical fluctuations. These findings are consistent with the results of recent studies for the United States, Canada and Europe, where common shocks have also been found to dominate regional cyclical activity.
