This paper examines German reunification from its inception. It shows that after the rapid expansion of the early years, former East Germany entered a phase of slow growth that made it impossible to bridge the gap with West Germany. Unemployment remains high, low growth rates appear ingrained,...

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...

Monetary growth targeting is often seen as an effective way of supporting macroeconomic stability. We scrutinize this property by checking whether multiplicity of equilibria, in the form of local indeterminacy (LI), can be both a possible and a plausible outcome of a basic model with an...

Empirical studies show that successful disinflations entail a period of output contraction. Using a medium-scale New Keynesian model, we compare the effects of disinflations of different speed and timing, implemented through either a money supply or an interest rate rule. In terms of...
