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...

We explore the consequences of different financial frictions on the corporate and banking level for macroeconomic policy responsiveness to major policy measures. We show that both corporate and bank debt overhang greatly reduce the effectiveness of fiscal policy: multipliers turn negative with...

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 standard macroeconomic models, debt sustainability and price level determinacy are achieved when fiscal policy avoids explosive debt and monetary policy controls inflation, irrespective of the relative strengths of each policy stance. We examine how these policy requirements for equilibrium...

What could be the drivers of low real rates? What are the implications of the Zero Lower Bound for economic policy? To discuss these questions we introduce a full general equilibrium model of the world economy with a simple (2 period) intertemporal structure. The model is simple enough to allow...
