Can macroprudential foreign exchange (FX) regulations on banks reduce the financial and macroeconomic vulnerabilities created by borrowing in foreign currency? To evaluate the effectiveness and unintended consequences of macroprudential FX regulations, we develop a parsimonious model of bank and...

The outreach of macroprudential policies is likely limited in practice by imperfect regulation enforcement, whether due to shadow banking, regulatory arbitrage, or other regulation circumvention schemes. We study how such concerns affect the design of optimal regulatory policy in a workhorse...

We analyze a variant of the Diamond-Dybvig (1983) model of banking in which savers can use a bank to invest in a risky project operated by an entrepreneur. The savers can buy equity in the bank and save via deposits. The bank chooses to invest in a safe asset or to fund the entrepreneur. The...

Domestic prudential regulation can have unintended effects across borders and may be less effective in an environment where banks operate globally. Using U.S. micro-banking data for the first quarter of 2000 through the third quarter of 2013, this study shows that some regulatory changes indeed...

Do sophisticated international financial markets obviate the need for an active union-wide authority to orchestrate fiscal transfers between countries to provide adequate insurance against country-specific economic fluctuations? We argue that they do. Specifically, we show that in a benchmark...

The paper explicates the issues raised for macroprudential regulation in a global economy with high capital mobility. The study surveys the recent literature and aims to translate the academic rationale for such policies, in which market imperfections lead to external effects that require policy...

We propose a theory of regulatory arbitrage by banks and test it using trust preferred securities (TPS) issuance. From 1996 to 2007, U.S. banks in the aggregate increased their regulatory capital through issuance of TPS while their net issuance of common stock was negative due to repurchases. We...

Forbes and Warnock (2012) identify episodes of extreme capital flow movements--surges, stops, flight, and retrenchment--and find that global factors, especially global risk, are significantly associated with extreme capital flow episodes whereas domestic macroeconomic characteristics and capital...

This paper offers a framework for regulating internalities. Using a simple economic model, we provide four principles for designing and evaluating behaviorally-motivated policy. We then outline rules for determining which contexts reliably reflect true preferences and discuss empirical...

Have bank regulatory policies and unconventional monetary policies—and any possible interactions—been a factor behind the recent “deglobalisation” in cross-border bank lending? To test this hypothesis, we use bank-level data from the UK—a country at the heart of the global financial...
