We embed a lockdown choice in a simplified epidemiological model and derive formulas for the optimal lockdown intensity and duration. The optimal policy re- ects the rate of time preference, epidemiological factors, the hazard rate of vaccine discovery, learning effects in the health care...

We contrast the canonical epidemiological SIR model due to Kermack and McKendrick (1927) with more tractable alternatives that offer similar degrees of "realism" and exibility. We provide results connecting the different models which can be exploited for calibration purposes. We use the expected...

The proposed revision of the Swiss Banking Act introduces a public liquidity backstop (PLB) for distressed systemically important banks (SIBs), in part to facilitate resolution. We examine the impact of the PLB on fiscal balances, societal welfare, and the incentives of bank shareholders and...

We investigate how politico-economic factors shaped government responses to the spread of COVID-19. Our simple framework uses epidemiological, economic and politico-economic arguments. Confronting the theory with US state level data we find strong evidence for partisanship even when we control...

We analyze retail central bank digital currency (CBDC) in a two-tier monetary system with bank deposit market power and externalities from liquidity transformation. Resource costs of liquidity provision determine the optimal monetary architecture and modified Friedman (1969) rules the optimal...

We document that creditor losses ("haircuts") during sovereign debt restructurings vary across debt maturity. In our novel dataset on instrument-specific haircuts suffered by private creditors in 1999-2020 we find larger losses on short- than long-term debt, independently of the specific haircut...

We develop a flexible single-state model to represent tradeoffs between infections and activity during the early phase of an epidemic. We prove that optimal policy is continuous in the state but discontinuous in the deterministic arrival date of a cure; optimal lockdowns are followed by stimulus...

Rejecting a common assumption in the sovereign debt literature, we document that creditor losses ("haircuts") during sovereign restructuring episodes are asymmetric across debt instruments. We code a comprehensive dataset on instrument-specific haircuts for 28 debt restructurings with private...

This paper reviews theoretical results on financial policy. We use basic accounting identities to illustrate relations between gross assets and liabilities, net debt positions and the appropriation of (primary) budget surplus funds. We then discuss Ramsey policies, answering the question how a...

We propose a theory of tax centralization in politico-economic equilibrium. Taxation has dynamic general equilibrium implications which are rationally internalized at the federal, but not at the regional level. The political support for taxation therefore differs across levels of government....
