We develop a dynamic model of investment, capital structure, leasing, and risk management based on firms' need to collateralize promises to pay with tangible assets. Both financing and risk management involve promises to pay subject to collateral constraints. Leasing is strongly collateralized...

Both financing and risk management involve promises to pay that need to be collateralized, resulting in a financing versus risk management trade-off. We study this trade-off in a dynamic model of commodity price risk management and show that risk management is limited and that more financially...

We propose a theory of credit lines provided by banks to firms as a form of monitored liquidity insurance. Bank monitoring and resulting revocations help control illiquidity-seeking behavior of firms insured by credit lines. The cost of credit lines is thus greater for firms with high liquidity...

We build an equilibrium model of commodity markets in which speculators are capital constrained, and commodity producers have hedging demands for commodity futures. Increases in producers' hedging demand or speculators' capital constraints increase hedging costs via price-pressure on futures....

We study the exposure of the US corporate bond returns to liquidity shocks of stocks and Treasury bonds over the period 1973–2007 in a regime-switching model. In one regime, liquidity shocks have mostly insignificant effects on bond prices, whereas in another regime, a rise in illiquidity...

This study uses corporate tax return data to examine the evolution of firms' financial structure and performance after leveraged buyouts (LBOs) for a comprehensive sample of 317 LBOs taking place between 1995 and 2007. We find little evidence of operating improvements subsequent to an LBO,...

Because the personal tax treatments of interest and dividend income likely affect the relative cost of debt and equity financing, a sharp change in tax treatment could affect firms' optimal leverage. This paper examines the effect of the 2003 equity income tax cut on firms' debt usage. Because...

This paper studies the relationship between firm leverage and supplier market structure. We find that firm leverage decreases with the degree of competition between suppliers. Specifically, leverage decreases with the elasticity of substitution between suppliers. Leverage also decreases with the...

This paper presents evidence that firms choose conservative financial policies partly to mitigate workers' exposure to unemployment risk. We exploit changes in state unemployment insurance laws as a source of variation in the costs borne by workers during layoff spells. We find that higher...

We administer psychometric tests to senior executives to obtain evidence on their underlying psychological traits and attitudes. We find US CEOs differ significantly from non-US CEOs in terms of their underlying attitudes. In addition, we find that CEOs are significantly more optimistic and...
