We shed light on the function, properties and optimal size of austerity using the standard sovereign model augmented to include incomplete information about credit risk. Austerity is defined as the shortfall of consumption from the level desired by a country and supported by its repayment...

In der öffentlichen Diskussion gibt es immer wieder Wissenschaftler, die für eine Abschaffung des Bargelds plädieren. Ihrer Ansicht nach würde ein solcher Schritt die faktische Zinsuntergrenze von null beseitigen und damit der Geldpolitik weiteren Handlungsspielraum eröffnen. Zudem...

We develop a sovereign debt model with official and private creditors where default risk depends on both the level and the composition of liabilities. Higher exposure to official lenders improves incentives to repay but carries extra costs, such as reduced ex-post flexibility. The model implies...

We analyze motivations for, and possible alternatives to, the Stability and Growth Pact (SGP). With regard to the former, we identify domestic policy failures and various cross-country spillover effects; with regard to the latter, we contrast an economic-theory perspective on optimal corrective...

We extend economic equivalence results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are politico-economically...

We investigate how politico-economic factors shaped government responses to the spread of COVID-19. Our simple framework uses epidemiological, economic and politico-economic arguments. Confronting the theory with US state level data we find strong evidence for partisanship even when we control...
