Several countries have recently introduced national capital standards exceeding the internationally coordinated Basel III rules, thus suggesting a ‘race to the top’ in capital standards. We study regulatory competition when banks are heterogeneous and give loans to firms that produce output...

We build a stylized dynamic general equilibrium model with financial frictions to analyze costs and benefits of capital requirements in the short-term and long-term. We show that since increasing capital requirements limits the aggregate loan supply, the equilibrium loan rate spread increases,...

Financial institutions are increasingly linked internationally. As a result, financial crisis and government intervention have stronger effects beyond borders. We provide a model of international contagion allowing for bank bailouts. While a social planner trades off tax distortions, liquidation...

Many countries offer state credit guarantee programs to improve access to finance for exporting firms. In the case of Germany, accumulated returns to the scheme deriving from risk-compensating premia have outweighed accumulated losses over the past 60 years. Why do private financial agents not...

Reportedly, firms often find it impossible to finance large and long-term projects despite positive net present values. Should governments step in and can their assistance be effective? This paper studies the case of public export credit guarantees in Germany. Covering the default risk of...

We present a simple neoclassical model to explore how an aggregate bank-capital requirement can be used as a macroeconomic policy tool and how this additional tool interacts with monetary policy. Aggregate bank-capital requirements should be adjusted when the economy is hit by cost-push shocks...

We introduce a model of the banking sector that formally incorporate 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...

This paper studies loan activity in a context where banks must follow Basel Accord-type rules and acquire financing from households. Loan activity typically decreases when entrepreneurs' investment returns decline, and we study which type of policy could revigorate an economy in a trough. We...
