SUMMARY:Nikhil VELLODI (PSE) - "Self-Prospecting: Optimal Experimentation Under Present-Bias"
DESCRIPTION:Séminaire Microéconomie : Tous les mercredis\nHeure : 12h15 – 13h30\nDate : 17/09/2026\nSalle : 3001 \nNikhil VELLODI (PSE) – “Self-Prospecting: Optimal Experimentation Under Present-Bias” \nCV : A present-biased decision maker (DM) faces a two-armed bandit problem whose risky arm generates random payoffs at exponentially distributed times. Under full information\, the DM’s belief remains unchanged prior to payoff arrivals\, generating a “lumpy” belief process that updates infrequently but conclusively. Our main finding is that coarsening the DM’s information to foster `”gradual optimism” – a continuously increasing path of beliefs during active experimentation – helps motivate the DM more effectively and deliver them greater welfare. We relate our findings to those in behavioral psychology relating to motivation\, learning\, and self-control\, and apply our results to parenting and pedagogy. \nJoint work with : Polina Borisova (PSE) \nOrganisateurs : \nJulien COMBE (Pôle d’Economie du CREST)\n​​​​​​​​​​​​Yves Le YAOUANQ (Pôle d’Economie du CREST)\n​​​​​​​​​Matias NUNEZ (Pôle d’Economie du CREST) \nCommanditaires :\nCREST \n

SUMMARY:Olivier GUEANT (Université Paris-Cité)  "Cryptocurrencies and Interest Rates: Inferring Yield Curves in a Bondless Market"
DESCRIPTION:Mathematical Finance\nTime: 2.3 p.m\nDate:17th of September  2025\nRoom 3001 \nOlivier GUEANT (Université Paris-Cité) “Cryptocurrencies and Interest Rates: Inferring Yield Curves\nin a Bondless Market” \nAbstract : In traditional financial markets\, yield curves are widely available for countries (and\, by extension\, currencies)\, financial institutions\, and large corporates. These curves are used to calibrate stochastic interest rate models\, discount future cash flows\, and price financial products. Yield curves\, however\, can be readily computed only because of the current size and structure of bond markets. In cryptocurrency markets\, where fixed-rate lending and bonds are almost nonexistent as of early 2025\, the yield curve associated with each currency must be estimated by other means. In this paper\, we show how mathematical tools can be used to construct yield curves for cryptocurrencies by leveraging data from the highly developed markets for cryptocurrency derivatives. \nJoint work : Philippe Bergault (Dauphine)\, Sébastien Bieber\, (Dauphine) and Wenkai Zhang (LCH) \nOrganizers:  Roxanna DUMITRESCU – Jean-François CHASSAGNEUX \n  \n
