We show that a .scal expansion by the core economies of the euro area would have a large and positive impact on periphery GDP assuming that policy rates remain low for a prolonged period. Under our preferred model speci.cation, an expansion of core government spending equal to one percent of...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

Recent developments in many industrialized countries have triggered a debate on whether monetary policy is effective when the nominal interest rate is close to zero. When the nominal interest rate hits its lower bound, the monetary authority is no longer in a position to pursue a policy of...

I introduce the real cost channel in the benchmark New Keynesian model to study government spending multipliers. Even though this new model shows previous evidence that the output gap multiplier in normal times can be overestimated by ignoring the cost channel, I provide a simple Markov chain...

Different from the papers presented in this session, this one analyzes the lack of fiscal consolidation within a framework of tensions between the objectives of consolidation and price stability. By using a model of time inconsistency with fiscal objectives and a Government's budget constraint...

This note shows that the Italian Mini BOTs proposed in 2019 bore the potential neither to become Italian legal tender nor to practically increase Italian government debt, but to practically cause a mere reduction in taxation and thence in government spending or transfers. Since the Eurozone...

This study analyzes the effect of a money-financed policy for fiscal reform. We introduce a realistic setting in which real output is not given by an exogenous variable, but is determined by effective demand in a monetary growth model. Using this model, we compare the effects of the...

This paper studies the government spending multiplier in the presence of the cost channel of the nominal interest rate. I find that the spending multiplier of normal times declines markedly when this channel is introduced. The rise in government spending leads to a rise in the nominal interest...

We show that a fiscal expansion by the core economies of the euro area would have a large and positive impact on periphery GDP assuming that policy rates remain low for a prolonged period. Under our preferred model specification, an expansion of core government spending equal to one percent of...

This paper characterizes general properties of an economy that experiences deflation by investigating the long-run government budget constraint. A sufficient condition for deflation in an economy under a balanced budget is that the nominal interest rate is below the output growth rate. With a...
