Trading for Bailouts

Staff Working Paper 2020-23 Toni Ahnert, Caio Machado, Ana Elisa Pereira
In times of high uncertainty, governments often implement interventions such as bailouts to financial institutions. To use public resources efficiently and to avoid major spillovers to the rest of the economy, policy-makers try to identify which institutions should receive assistance.

Loan Insurance, Market Liquidity, and Lending Standards

Staff Working Paper 2019-47 Toni Ahnert, Martin Kuncl
Third parties often assume default risk at loan origination in return for a fee. Insurance, various guarantees and external credit enhancements protect the owner of the loan against borrower default. Governments often assume such default risk through guarantees for various types of loans, including mortgages, student loans and small business loans.

Bank Runs, Portfolio Choice, and Liquidity Provision

Macroprudential FX Regulations: Shifting the Snowbanks of FX Vulnerability?

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 market lending in domestic and foreign currency and derive four predictions.

Should Bank Capital Regulation Be Risk Sensitive?

Staff Working Paper 2018-48 Toni Ahnert, James Chapman, Carolyn A. Wilkins
We present a simple model to study the risk sensitivity of capital regulation. A banker funds investment with uninsured deposits and costly capital, where capital resolves a moral hazard problem in the banker’s choice of risk.

Seeking Safety

Staff Working Paper 2018-41 Toni Ahnert, Enrico Perotti
The scale of safe assets suggests a structural demand for a safe wealth share beyond transaction and liquidity roles. We study how investors achieve a reference wealth level by combining self-insurance and contingent liquidation of investment. Intermediaries improve upon autarky, insuring investors with poor self-insurance and limiting liquidation.
