The feedback loop between sovereign and financial sector insolvency has been identified as a key driver of the European debt crisis and has motivated an array of policy proposals. We revisit this "doom loop" focusing on governments' incentives to default. To this end, we present a simple...

I propose a dynamic general equilibrium model in which strategic interactions between banks and depositors may lead to endogenous bank fragility and slow recovery from crises. When banks’investment decisions are not contractible, depositors form expectations about bank risk-taking and demand a...

A sovereign's inability to commit to a course of action regarding future borrowing and default behavior makes long-term debt costly (the problem of debt dilution). One mechanism to mitigate the debt dilution problem is the inclusion of a seniority clause in sovereign debt contracts. In the event...

How do oil price movements affect sovereign spreads in an oil-dependent economy? I develop a stochastic general equilibrium model of an economy exposed to co-moving oil price and output processes, with endogenous sovereign default risk. The model explains a large proportion of business cycle...

The steady application of Quantitative Easing (QE) has been followed by big and non-monotonic effects on international asset prices and international capital flows. These are difficult to explain in conventional models, but arise naturally in a model with collateral. This paper develops a...

We develop a dynamic recursive model where political and economic decisions interact, to study how excessive debt-GDP ratios affect political sustainability of prudent fiscal policies. Rent seeking groups make political decisions - to cooperate (or not) - on the allocation of fiscal budgets...
