Do digital payment technologies generate liquidity premia like cash and Treasury? We provide an estimate in the context of the world's largest digital payment platform, Alipay. Our empirical strategy exploits the variation in the timing of the introduction of money market funds that users on...

This paper examines persistence and nonlinearities in the US Federal Funds rate over the period from July 1954 to April 2025 by using fractional integration methods. More precisely, a general model including both deterministic and stochastic components is estimated under alternative assumptions...

In this paper we model the volatility of the spread between the overnight interest rate and the central bank policy rate (the policy spread) for the euro area and the UK during the two main phases of the financial crisis that began in late 2007. During the crisis, the policy spread exhibited...

We develop a model where banks invest in reserves and loans, and face aggregate liquidity shocks. Banks with liquidity shortage sell loans on the interbank market. Two equilibria emerge. In the no default equilibrium, all banks hold enough reserves and remain solvent. In the mixed equilibrium,...

The eurozone has a single short-term nominal interest rate, but monetary policy conditions measured by real short-term interest rates varied substantially across countries in the period 2003 - 2010. We use this cross-country variation in the (local) tightness of monetary policy to examine its...

An increasing number of central banks implement monetary policy via two standing facilities: a lending facility and a deposit facility. In this paper we show that it is socially optimal to implement a non-zero interest rate spread. We prove this result in a dynamic general equilibrium model...

We study differences in the price paid for liquidity across banks using price data at the individual bank level. Unique to this paper, we also have data on individual banks' reserve requirements and actual reserve holdings, thus allowing us to gauge the extent to which a bank is short or long...

We analyze the impact of introducing a central bank-issued digital currency (CBDC) on the operational framework of monetary policy and the macroeconomy as a whole. To this end, we develop a New Keynesian model with heterogeneous banks, a frictional interbank market, a central bank with deposit...

We analyze whether or not the globalization of capital, "disciplines" governments and improves governance. We demonstrate that globalization affects governance, by increasing a country's vulnerability to sudden capital flight. This increased threat of capital flight can discipline governments...

We explore the impact of large banks and of financial openness for aggregate growth. Large banks matter because of granular effects: if markets are very concentrated in terms of the size distribution of banks, idiosyncratic shocks at the bank-level do not cancel out in the aggregate but can...
