We quantify the impact that central bank refinancing o perations a nd f unding f acilities had at reducing the banking sector's intrinsic fragility in the euro area in 2014-2019. We do so by constructing, estimating and calibrating a micro-structural model of imperfect competition in the banking...

We propose a small open economy model where agents borrow internationally and invest in liquid foreign assets to insure against liquidity shocks, which temporarily shut out the economy of short-term credit markets. Due to the presence of a pecuniary externality individual agents borrow too much...

I establish a theoretical framework to address three distinct, but interrelated puzzles in international economics: (1) the occurrence of twin crises, (2) the existence of large amounts of sovereign debt, and (3) the presence of substantial amounts of international reserves. By considering the...

Motivated by the Chinese experience, we analyze a semi-open economy where the central bank has access to international capital markets, but the private sector has not. This enables the central bank to choose an interest rate different from the international rate. We examine the optimal policy of...

This paper discusses commercial banks’ demand for central bank reserves under two alternative monetary policy framework configurations, namely: (i) an interest rate corridor system with scarce liquidity, and (ii) a floor system with ample liquidity. It outlines the interaction between the...

The aim is to show how and when government insolvency implies a fixed exchange rate regime crisis. To model these issues I try to unify a stylized macroeconomic model with a standard micro agent behavior toward asset pricing. The equilibrium condition between demand and supply of public debt,...

We study the consequences for business cycles and welfare of introducing an interest-bearing retail CBDC, competing with bank deposits as medium of exchange, into an estimated 2-country DSGE environment. CBDC issuance of 30% of GDP increases output and welfare by around 6% and 2%, respectively....

I study the Ramsey problem for three unconventional monetary policies in a twocountry model. An equity injection into financial intermediaries is the most efficient policy. Due to precautionary effects of future risk, a central bank should exit from these policies in accordance with but slower...

We study spillover effects of US uncertainty fluctuations using panel data from fifteen emerging market economies (EMEs). A US uncertainty shock negatively affects EME stock prices and exchange rates, raises EME country spreads, and leads to capital outflows from them. Moreover, it decreases EME...
