BACCARA Mariagiovanna : Optimal Dynamic Matching

Résumé
We study a dynamic matching environment where individuals arrive sequentially. There is a tradeoff between waiting for a thicker market, allowing for higher quality matches, and minimizing agentsí waiting costs. The optimal mechanism cumulates a stock of incongruent pairs up to a threshold and matches all others in an assortative fashion instantaneously. In decentralized settings, a similar protocol ensues in equilibrium, but expected queues are inefficiently long. We quantify the welfare gain from centralization, which can be substantial, even for low waiting costs. We also evaluate welfare improvements generated by transfer schemes and by matching individuals in fixed time intervals.

BLANCHET Thomas : Generalized Pareto Curves : Theory and Applications
FOURNIER Juliette and PIKETTY Thomas

Résumé
We define generalized Pareto curves as the curve of inverted Pareto coefficients b(p), where b(p) is the ratio between average income or wealth above rank p and the p-th quantile Q(p) (i.e. b(p) = E[X|X > Q(p)]/Q(p)). We use them to characterize and visualize power laws. We develop a method to nonparametrically recover the entire distribution based on tabulated income or wealth data as is generally available from tax authorities, which produces smooth and realistic shapes of generalized Pareto curves. Using detailed tabulations from quasi-exhaustive tax data, we demonstrate the precision of our method both empirically and analytically. It gives better results than the most commonly used interpolation techniques. Finally, we use Pareto curves to identify recurring distributional patterns, and connect those findings to the existing literature that explains observed distributions by random growth models.

DAVIS Lucas (Haas Business School, UC Berkeley) : Do Energy Eciency Investments Deliver at the Right Time ? _BOOMHOWER Judson

Résumé
Electricity cannot be cost-eectively stored even for short periods of time. Consequently, wholesale electricity prices vary widely across hours of the day with peak prices frequently exceeding o-peak prices by a factor of ten or more. Most analyses of energy-eciency policies ignore this variation, focusing on total energy savings without regard to when those savings occur. In this paper we demonstrate the importance of this distinction using novel evidence from a rebate program for air conditioners in Southern California. We estimate electricity savings using previously unavailable hourly \smart-meter data and show that savings tend to occur during hours when the value of electricity is high. This signicantly increases the overall value of the program, especially once we account for the large capacity payments received by generators to guarantee their availability in high-demand hours. We then compare this estimated savings prole with engineering-based estimates for this program as well as a variety of alternative energy-eciency investments. The results illustrate a surprisingly large amount of variation in economic value across investments.
