Existing theories of a firm's optimal capital structure seem to fail in explaining why many healthy and profitable firms rely heavily on equity financing, even though benefits associated with debt (like tax shields) appear to be high and the bankruptcy risk low. This holds in particular for...

This paper reports estimates of the long-run costs and benefits of banks funding more of their assets with loss-absorbing capital, or equity. Measuring those costs requires careful consideration of a wide range of issues about how shifts in funding affect required rates of return and on how...

This paper tests for the sensitivity of R&D to financing constraints conditional on restrictions in external financing. Financing constraints of firms are identified by an exogenously calculated rating index. Restrictions in external financing are determined by (i) the specific time period...

Using a Bayesian vector autoregression (BVAR) identified with a mix of sign and zero restrictions, we show that a restrictive bank loan supply shock has a strong and persistent negative impact on real GDP and the GDP deflator. This result comes about even though flows of other sources of...

We estimate a dynamic structural banking model to examine the interaction between risk-weighted capital adequacy and unweighted leverage requirements, their differential impact on bank lending, and equity buffer accumulation in excess of regulatory minima. Tighter risk-weighted capital...

Why do people engage in entrepreneurship and commit large parts of their personal wealth to their business, despite comparably low returns and high risk? This paper connects several streams of literature to shed some light on this puzzle and suggests possible future research avenues. Key...

We introduce a model of the banking sector that formally incorporates a buffer function of capital. Heterogeneous banks choose their portfolio risk, bank size, and capital holdings. Banks voluntarily hold equity when the buffer effect against the risk of default outweighs the cost advantages of...

In recent years, some European countries have relied on elements of an allowance for corporate equity (ACE) in the design of their tax systems. We analyse the effects of ACE-based taxation on rates of return and effective tax rates. Investment neutrality is lost if the imputed interest rate...
