Le LabEx ReFi est un laboratoire de recherche pluridisciplinaire dédié à l’évaluation des politiques de régulation. Il vise à (i) faire progresser la connaissance du fonctionnement des systèmes financiers et de leur régulation et à (ii) “conseiller” et “guider” en toute indépendance l’action des pouvoirs publics dans la mise en œuvre des politiques de régulation en apportant une expertise et une rigueur académique. Le LabEx ReFi a été constitué à l’initiative du Cnam, de l’Ena, de l’Université Paris I Panthéon Sorbonne et d’ESCP Europe (« porteur » du projet) dans le cadre du grand emprunt. En savoir plus ici

We are having Ryan Williams (University of Arizona) next Friday in our ReFi research seminar series (see here for more information).
Ryan will be available to meet with the faculty and PhD students during the afternon. If you are interested in meeting him, please send an email to Thomas David (tdavid@escpeurope.eu) indicating which of the following time slots suits you best:
14.30-15.00, 15.00-15.30, 15.30-16.00, 16.00-16.30, 16.30-17.00, 17.00-17.30

Abstract 

Non-compete agreements limit the mobility of employees, thereby imposing significant costs by reducing their outside options.  In this paper, we focus on CEO non-compete agreements largely because CEOs have a better ability to negotiate their employment contracts than rank-and-file employees and their joining a competitor is likely to cause the greatest economic damage to the firm. Specifically, using hand collected data on CEO non-compete agreements, we examine: (i) the determinants of CEO non-compete agreements, (ii) the impact of CEO non-compete agreements on the CEO performance-turnover sensitivity, and (iii) how CEO non-compete agreements affect the level and structure of CEO compensation. We find evidence that is consistent with the argument that the presence of a non-compete agreement is the outcome of a bargaining game between the CEO and the firm. Consistent with the idea that non-compete agreements lower the likelihood that a departing CEO can create economic harm to the firm by joining a competitor, we find that the CEO performance-turnover sensitivity is significantly stronger when the CEO has a non-compete agreement in place. Finally, we find that CEO total compensation is higher if CEOs have non-compete contracts, but that the firm pays such compensation as incentive-based pay, consistent with the ex-post realization of the ex-ante bargaining game. We exploit staggered state-level changes in non-compete enforceability to establish causality. Our paper illustrates the impact of restrictions of CEO mobility on how CEOs are monitored and compensated by the firm.

Abstract

The thesis introduces simulation techniques that are based on particle methods and it consists of two parts, namely rare event simulation and a homotopy transport for stochastic volatility model estimation.

 

Particle methods, that generalize hidden Markov models, are widely used in different fields such as signal processing, biology, rare events estimation, finance, etc. There are a number of approaches that are based on Monte Carlo methods that allow to approximate a target density such as Markov Chain Monte Carlo (MCMC), sequential Monte Carlo (SMC). We apply SMC algorithms to estimate default probabilities in a stable process based intensity process to compute a credit value adjustment (CVA) with a wrong way risk (WWR). We propose a novel approach to estimate rare events, which is based on the generation of Markov Chains by simulating the Hamiltonian system. We demonstrate the properties, that allows us to have ergodic Markov Chain and show the performance of our approach on the example that we encounter in option pricing.

 

In the second part, we aim at numerically estimating a stochastic volatility model, and consider it in the context of a transportation problem, when we would like to find « an optimal transport map » that pushes forward the measure. In a filtering context, we understand it as the transportation of particles from a prior to a posterior distribution in pseudotime. We also proposed to reweight transported particles, so as we can direct to the area, where particles with high weights are concentrated. We showed the application of our method on the example of option pricing with Stein-Stein stochastic volatility model and illustrated the bias and variance.
