In an intertemporal general equilibrium framework, we compare a Cournot equilibrium to the Walras equilibrium. The Cournot agents trade and invest less than the Walras agents. This generates an inefficiency that does not vanish as the number of Cournot agents tends to infinity. A larger number...

Why should countries buy expensive catastrophe insurance? Abstracting from risk aversion or hedging motives, this paper shows that catastrophe insurance may have a catalytic role on external finance. Such effect is particularly strong in those middle-income countries that face financial...

Is generalized debt relief an effective development strategy, or should assistance be tailored to countries' characteristics? To answer this question, the authors build a simple model in which recipient governments reveal their creditworthiness if donors offer them to choose between aid and debt...

The standard macro(prudential) models focus on externalities and treat all prudential instruments as alternative, but equivalent, forms of Pigouvian taxes. This paper explicitly models individual banks' risk choices and shows that different prudential instruments affect banks' risk-taking...

Using a new, large data set on quarterly reserve requirements for the period 1970-2011, this paper provides new evidence on the use of reserve requirements as a countercyclical macroprudential tool in developing countries. The appeal of reserve requirements lies in the pro-cyclical behavior of...

This paper looks at the correlation between the cyclical components of gross domestic product and the exchange rate and classifies countries' currencies as procyclical if they appreciate in good times, countercyclical if they appreciate in bad times, and acyclical otherwise. With this...

This paper investigates how the devolution of oil windfalls affects the likelihood of political violence. It shows that transferring large shares of oil wealth can prevent conflict, while transferring small shares can trigger it. Among the different transfer schemes, fiscal transfers (to...

This paper computes a new financial globalization index for a large sample of countries for 1992-2016. Unlike other measures, the financial globalization index corrects for the heteroscedasticity of global volatility. This leads to a downward adjustment of financial globalization trends for...
