The Monetary Entanglement between CBDC and Central Bank Policies, with L. Somoza and T. Terracciano  [paper] NEW VERSION!* 

Using a two-period equilibrium model, we show that the effects of introducing a Central Bank Digital Currency (CBDC) depend on the ongoing monetary policy. We derive neutrality conditions without direct pass-through policies and find that they do not always hold with quantitative easing, as bank lending shrinks if demand for CBDC is above a certain threshold. Moreover, we find that commercial banks optimally liquidate excess reserves in the system to accommodate households’ demand for CBDC. This leads to the replacement of banks with households on the liability side of the central bank balance sheet, making quantitative tightening difficult to implement.

CBDC and Banks: Threat or Opportunity?, with L. Somoza and T. Terracciano  [paper]

A Central Bank Digital Currency (CBDC) would reduce commercial bank deposits and provide households with a new payment technology. We develop a structural model of the banking sector, calibrate it, and introduce a CBDC to run counterfactual analyses. We find that, if the central bank compensates the commercial banks for the loss in deposits, then banks optimally push households towards the CBDC. This allows banks to capture the consumer surplus stemming from the new technology and increase their profit margin. The design of the compensation mechanism can mitigate this effect.

FX Hedging, Currency Choice, and Dollar Dominance, with T. Terracciano  [paper available upon request]

When exporters price their goods in a foreign currency, they are exposed to exchange-rate risk. However, they can hedge this risk by underwriting a foreign exchange (FX) forward contract, which means selling forward the currency in which they price their goods. In this paper, we study how the cost of FX hedging influences the currency choice of French exporters. Our identification strategy exploits an exogenous increase in the trading costs of FX forward contracts, that was triggered by a spike in the Greek default risk. First, we find that higher FX trading costs lower the probability of pricing in dollars and in local (i.e., buyer’s) currency for hedging firms. Second, we show that hedging firms price more their goods in dollars than in local currency. Third, we document that FX hedging affects the transmission of exchange-rate shocks to prices and find that FX hedging is associated with lower levels of exchange-rate pass-through. We conclude that FX hedging contributes to dollar dominance and to the exchange-rate disconnect puzzle.

Government Venture Capital: Investing for the Common Good?, with A. Maino and L. Somoza  [paper] New version coming soon!

This paper examines the rationale behind the sharp increase in direct Government investments in Venture Capital (GVCs) over the past two decades. We find that GVCs are not pure profit maximizers but rather seek to capture positive externalities. Using EU data from 2002 to 2020, we find that GVCs have lower performance but that they target more innovative and geographically dispersed firms. Furthermore, we derive the conditions under which GVCs can crowd in private investments and show consistent empirical evidence. These findings suggest that governments have a role to play in promoting innovation and entrepreneurship.

Network and Risk in Venture Capital Investing [paper available upon request]

Does the network of venture capital firms affect the risk they are willing to take in their investment decisions? I develop a theoretical model of the venture capital investing process and I empirically test its implications. The model considers a representative venture capital fund that decides whether to invest in a startup, and whether to syndicate with another fund. I find that a better connected venture capitalist is able to take more risk, because she is able to improve the company performance with her contacts. Moreover, poorly connected venture capital firms are more likely to enter a syndication, especially when the co-investors are well connected. Finally, I use the Crunchbase database to empirically verify these implications.
