A simple model of multiple equilibria and default. CEPS Working Document No. 366, 16 July 2012

This Working Document by Daniel Gros presents a simple model that incorporates two types of sovereign default cost: first, a lump-sum cost due to the fact that the country does not service its debt fully and is recognised as being in default status, by ratings agencies, for example. Second, a cost that increases with the size of the losses (or haircut) imposed on creditors whose resistance to a haircut increases with the proportional loss inflicted upon them. One immediate implication of the model is that under some circumstances the creditors have a (collective) interest to forgive some debt in order to induce the country not to default. The model exhibits a potential for multiple equilibria, given that a higher interest rate charged by investors increases the debt service burden and thus the temptation to default. Under very high debt levels credit rationing can set in as the feedback loop between higher interest rates and the higher incentive to default can become explosive. The introduction of uncertainty makes multiple equilibria less likely and reduces their range.

Unholy compromise in the eurozone and how to right it. CEPS Policy Brief No. 277, 16 July 2012

This paper reviews the causes of the ongoing crisis in the eurozone and the policies needed to restore stability in financial markets and reassure a bewildered public. Its main message is that the EU will not overcome the crisis until it has a comprehensive and convincing set of policies in place; able to address simultaneously budgetary discipline and the sovereign debt crisis, the banking crisis, adequate liquidity provision by the ECB and dismal growth. The text updates and expands on his Policy Brief contributed in the run-up to the emergency European Council meeting at the end of June.

The challenges of Europe's fourfold union. Bruegel Policy Contribution 2012/13, 16 August 2012

Five years after the first tremors in Europe’s banking system, what makes the crisis unique is the absence of a democratically accountable decision-making framework; there is an 'executive deficit' that compounds Europe’s democratic deficit. The author argues that the only way to resolve the crisis successfully is a sustained effort to achieve a 'fourfold union' agenda: banking union, fiscal union, competitiveness union and political union. Progress must be made in parallel on each of the four components. In particular, successful progress towards banking union requires a combination of short term action, including the establishment of a temporary resolution authority to identify undercapitalised banks and to restructure them, and longer-term measures, including the creation of permanent authorities for supervision, resolution and deposit insurance.
