“Austerity,” EJ, forthcoming

Economic Journal, forthcoming, with Harris Dellas. PDF.

We study the optimal debt and investment decisions of a sovereign with private information. The separating equilibrium is characterized by a cap on the current account. A sovereign repays debt amount due that exceeds default costs in order to signal creditworthiness and smooth consumption. Accepting funding conditional on investment/reforms relaxes borrowing constraints, even when investment does not create collateral, but it depresses current consumption. The model contains the signalling elements emphasized by creditors in the Greek austerity programs and is consistent with the reduction in the loans issued by Greece and their interest rate following the 2015 election.

Universities

The Economist featured a special report on universities. Some elements:

On the value added of university education (see this article):

Employers are not much interested in the education universities provide either. Lauren Rivera of Northwestern University’s Kellogg School of Management interviewed 120 recruiters from American law firms, management consultancies and investment banks. Their principal filter was the applicant’s university. Unless he had attended one of the top institutions, he was not even considered. “Evaluators relied so intensely on ‘school’ as a criterion of evaluation not because they believed that the content of elite curricula better prepared students for life in their firms…but because of the perceived rigour of the admissions process,” Ms Rivera wrote. After the status of the institution, recruiters looked not at students’ grades but at their extracurricular activities, preferring the team sports—lacrosse, field-hockey and rowing—favoured by well-off white men.

On rankings (see this article): More than 50 of the top 100 universities (according to the Shanghai ranking) are located in the US. Switzerland has the highest density of these institutions per capita (6.2 top universities per 10m people, next is Sweden before the Netherlands).

On public and private funding (see this article):

“Austerity,” CEPR, 2014

CEPR Discussion Paper 10315, December 2014, with Harris Dellas. PDF. Also published as CESifo Working Paper 5146, Study Center Gerzensee Working Paper 14-07. PDF, PDF.

We shed light on the function, properties and optimal size of austerity using the standard sovereign debt 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 capacity. We find that austerity serves as a tool for securing a more favorable loan package; that it is associated with over‐investment even when investment does not create collateral; and that low risk borrowers may favour more to less severe austerity. These findings imply that the amount of fresh funds obtained by a sovereign is not a reliable measure of austerity suffered; and that austerity may actually be associated with higher growth. Our analysis accommodates costly signalling for gaining credibility and also assigns a novel role to spending multipliers in the determination of optimal austerity.
