How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...

The paper discusses global imbalances under the aspect of an asymmetric world monetary system. It identifies the US and Germany as center countries with rising/high current account deficits (US) and surpluses (Germany). These are matched by current account surpluses of countries stabilizing...

We assess the sustainability of public finances in OECD countries, over the period 1970-2010, using unit root and cointegration analysis, both country and panel based, controlling for endogenous breaks. Results notably show: lack of cointegration – absence of sustainability – between...

We investigate the impact of fiscal stimuli at different levels of the government debt-to-GDP-ratio for a sample of 17 European countries from 1970 to 2010. This is implemented in an interacted panel VAR framework in which all coefficient parameters are allowed to change continuously with the...

Identifying fiscal multipliers is usually constrained by the absence of a counterfactual scenario. Our new data set allows overcoming this problem by making use of the fact that recommendations under the EU's excessive deficit procedure (EDP) provide both a baseline no-policy-change scenario and...

The euro area has been experiencing a prolonged period of weak economic activity and very low inflation. This paper reviews models of business cycle stabilization with an eye to formulating lessons for policy in the euro area. According to standard models, after a large recessionary shock...

In response to the coronavirus (Covid-19) pandemic, there has been a complementary approach to monetary and fiscal policy in the United States with the Federal Reserve System purchasing extraordinary quantities of securities and the government running a deficit of some 17% of projected GDP. The...

This paper studies stabilisation policies in a multi-country currency union of small open economies. It abstracts from key factors favouring currency union formation, such as reduced transaction costs and enhanced credibility, which are exogenous to the factors studied here. Demand-side shocks...

This paper analyses the empirical relationship between fiscal policy and the current account of the balance of payments and considers how Ricardian equivalence changes this relationship. To do so, we estimate a dynamic panel threshold model for 22 industrialised countries in which the...

This paper analyzes the effects of several policy instruments for mitigating financial bubbles generated in the banking sector. We augment a New Keynesian macroeconomic framework by endogenizing boundedly-rational expectations on asset values of loan portfolios, allow for interbank trading and...
