Helmuth Cremer, Firouz Gahvari et Pierre Pestieau, « Accidental bequests: a curse for the rich and a boon for the poor », The Scandinavian Journal of Economics, vol. 114, n° 4, décembre 2012, p. 1437–1459.

When accidental bequests signal otherwise unobservable individual characteris- tics such as productivity and longevity, the population should be partitioned into two groups: those who do not receive an inheritance those who do. The first tagged group gets a second-best tax à la Mirrlees; the second...

Bruno Biais, Florian Heider et Marie Hoerova, « Clearing, counterparty risk and aggregate risk », IMF Economic Review, n° 60, juillet 2012, p. 193–222.

The paper studies the optimal design of clearing systems. The paper analyzes how counterparty risk should be allocated, whether traders should be fully insured against that risk, and how moral hazard affects the optimal allocation of risk. The main advantage of centralized clearing, as opposed to...

Hippolyte D'Albis et Emmanuel Thibault, « Optimal annuitization, uncertain survival probabilities, and maxmin preferences », Economics Letters, Elsevier, vol. 115, n° 2, mai 2012, p. 296–299.

We consider a life-cycle model with bequest motives, and assume that the individual does not know his/her survival probability and has maxmin utility preferences;weshow that it is optimal not to annuitize but to purchase pure life insurance policies instead.

Money Runs (1)

Giorgia Piacentino (Washington University in St Louis)

TSE, 6 mars 2017, 12h30–14h00, salle MF 323

We present a banking model in which bank debt circulates in secondary markets, facilitating trade. The key friction is that secondary market trade is decentralized, i.e. bank debt is traded over the counter like banknotes were in the nineteenth century and repos are today. We find that bank debt is...

The Effect of Superstar Firms on College Major Choice (1)

Dong Lou (London School of Economics)

IDEI, 27 février 2017, 12h30–14h00, salle MF 323

We study the effect of superstar firms on an important human capital decision — college students’ choice of major. Past salient, extreme events in an industry, as proxied by cross-sectional skewness in stock returns (or in favorable news coverage), are associated with a disproportionately larger...

Mostly Prior-Free Asset Allocation (1)

Sylvain Chassang (Princeton University)

IDEI, 5 décembre 2016, 12h30–14h00, salle MF 323

This paper develops a prior-free version of Markowitz (1952)'s efficient portfolio theory that allows the decision maker to express preferences over risk and reward, even though she is unable to express a prior over potentially non-stationary returns. The corresponding optimal allocation strategies...

Collateral, Central Bank Repos, and Systemic Arbitrage (1)

Kjell Nyborg (University of Zürich)

Herding and Contrarianism: A Matter of Preference (1)

Chad Kendall (University of Southern California)

IDEI, 28 novembre 2016, 12h30–14h00, salle MF 323

Herding and contrarianism in financial markets produce informational inefficiencies when investors ignore their private information, instead following or bucking recent trends. I theoretically establish a preference-based link between the two behaviors: investors with prospect theory preferences...
