Banking regulation invites banks to gamble when buying government bonds that regulators consider to be risk-free. The adverse effects on financial stability are known. In turn, this study shows that governments have an incentive to use banking regulation in order to enhance their fiscal...

This paper models the strategic interaction between a rating agency, a bank and a bank regulator who lacks information about bank asset risk. The regulator can either (1) make bank capital requirements contingent on credit ratings; or (2) set rating-independent capital requirements. Truthful...

Limited liability and asymmetric information between an investment bank and its lenders provide an incentive for a bank to undercapitalise and finance overly risky business projects. To counter this market failure, national governments have imposed solvency constraints on banks. However, these...

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...

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,...

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 develop a simple model of banking regulation with two policy instruments: minimum capital requirements and supervision of domestic banks. The regulator faces a trade-off: high capital requirements cause a drop in the banks'; profitability, while strict supervision reduces the scope of...

We study the efficiency of banking regulation under financial integration. Banks freely choose the jurisdiction where to locate their activities and have private information about their efficiency level. Regulators non-cooperatively offer any regulatory contract that satisfies information and...

We set up a two-country, regional model of trade in financial services. Competitive firms in each country manufacture untraded consumer goods in an uncertain productive environment, borrowing funds from a bank in either the home or the foreign market. Duopolistic banks can choose their levels of...

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 in...
