This paper estimates the effects of technology shocks in VAR models of the U.S., identified by imposing restrictions on the sign of impulse responses. These restrictions are consistent with the implications of a popular class of DSGE models, with both real and nominal frictions, and with...

We consider an economy in which the oil costs, industrial production, and other macroeconomic variables fluctuate in response to fundamental domestic and external demand and supply shocks. We estimate the effects of these structural shocks on US monthly data for the 1973.1-2007.12 period using...

This paper builds a baseline two-country model of real and monetary transmission in the presence of optimal international price discrimination by firms. Distributing traded goods to consumers requires nontradables, intensive in local labor. Because of distributive trade the price elasticity of...

Advances in transaction technology allow agents to economize on the cost of cash management. We argue that accounting for the impact of new transaction technologies on currency holding behaviour is important to obtain theoretically consistent estimates of the demand for money. We modify a...

A Monetary Union is modeled as a technology that makes a surprise policy deviation impossible but requires voluntarily participating countries to follow the same monetary policy. Within a fully dynamic context, we identify conditions under which such arrangement may dominate a coordinated system...

It is known that discretionary policy may give rise to an inflationary bias if wages are negotiated in nominal terms. It has recently been argued that this bias can be eliminated, and welfare maximized, by the appointment of a central banker who does not care at all about inflation (a "populist"...

When a bank defaults or stops trading in the interbank market, both a liquidity shortage in the market itself and mounting trading losses should be anticipated. To gain more insight into the way a liquidity crisis spreads, we apply network topology techniques to monthly data on deposits...

This paper proposes a possible way of assessing the effect on interest rate dynamics of changes in the decision-making approach, in the communication strategy and in the operational framework of a central bank. Through a GARCH specification we show that the US and the euro area displayed a...

We analyze the main forces affecting financial system pro-cyclicality (the fact that developments in the financial sector can amplify business cycle fluctuations). We first review some major structural developments in financial markets that may influence pro-cyclicality and that have been...

This paper studies the interaction between monetary and fiscal authorities while investors are coordinating on a speculative attack. The authorities want to achieve specific targets for output and inflation but also to avoid a regime change (i.e. sovereign default). They use the traditional...
