This paper illustrates the paradox of prudential under-regulation in an economy that adopts financial reform, a reform which exposes the economy to future financial crises. There is individual-uncertainty about the crisis incidence, and the probability of the crisis is updated sequentially...

The overriding practical problem now is the tension between the global financial and market system and the national political and power structures. The main analytical short-coming lies in the failure to incorporate financial frictions, especially default, into our macro-economic models. Neither...

The Great Depression was marked by a severe outbreak of protectionist trade policies. But contrary to the presumption that all countries scrambled to raise trade barriers, there was substantial cross-country variation in the movement to protectionism. Specifically, countries that remained on the...

This paper studies the cross-country variation of the fiscal stimulus and the exchange rate adjustment propagated by the global crisis of 2008-9, identifying the role of economic structure in accounting for the heterogeneity of response. We find that greater de facto fiscal space prior to the...

During the global financial crisis 2007-2009 fiscal policy was widely used as a stabilization tool. Policymakers allowed a large build-up of public debt resulting from both automatic and discretionary expansionary measures. At the same time, calls for policy coordination stressed that...

We define the notion of a 'de facto fiscal space' of a country as the inverse of the tax-years it would take to repay the public debt. Specifically, we measure the outstanding public debt relative to the de facto tax base, where the latter measures the realized tax collection, averaged across...

In a dynamic optimising model with costly tax collection, a tax cut by one nation creates positive externalities for the rest of the world if initial public debt stocks are positive. By reducing tax collection costs, current tax cuts boost the resources available for current private consumption,...

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore cross-country spillovers of tax...

We study cross-country insurance in a currency union with nominal price and wage rigidities. We provide two results that build the case for the creation of a fiscal union within a currency union. First, we show that, if financial markets are incomplete, the value of gaining access to any given...

Two separate narratives have emerged in the wake of the Global Financial Crisis. One interpretation speaks of private financial excess and the key role of the banking system in leveraging and deleveraging the economy. The other emphasizes the public sector balance sheet over the private and...
