Interest rates on public debt have for several years now fallen short of GDP growth rates in much of the Western world. In his presidential address to the AEA Blanchard argued that this implies that there are no fiscal costs to high debt (Blanchard, 2019).1 In this paper we argue that the safe...

We analyse the poisonous interaction between bank rescues, financial fragility and sovereign debt discounts. In our model balance sheet constrained financial intermediaries finance both capital expenditure of intermediate goods producers and government deficits. The financial intermediaries face...

We investigate the effectiveness of "Keynesian" fiscal stimuli when government deficits and debt rollovers are (possibly partially) financed by balance sheet constrained financial intermediaries. Because financial intermediaries operate under a leverage constraint, deficit financing of fiscal...

It is well known that rational bubbles can be sustained in balanced growth path of a deterministic economy when the return to capital r is equal to the growth rate g. When there is a lack of stores of value, bubbles can implement an efficient allocation. This paper considers a world where r...

Conventional wisdom teaches that the output response upon a fiscal expansion is higher under fixed than floating exchange rates for a small open economy. We analyse the effects of fiscal expansions using a New Keynesian model and find that this result reverses in times of sovereign default risk....

In this note I argue that the desirability of fiscal policy in response to the current crisis depends on whether one views the current crisis as a temporary deviation from a unique equilibrium or as a bad equilibrium out of multiple equilibria. The paper presents a simple Diamond (1982) type of...

The financial trilemma states that financial stability, financial integration and national financial policies are incompatible. Any two of the three objectives can be combined but not all three; one has to give. This paper develops a model to underpin the financial trilemma. Our findings for...
