This talk aims to describe an algorithm for locating the barycenter of discrete structures like weighted graphs. Such structures are commonly used for database description, or for modeling internet communication modeling, road or airline traffic, etc. The computation of this kind of structure, for...

We study debt policy of emerging economies accounting for credit and liquidity risk. To account for credit risk we study an incomplete markets model with limited commitment and exogenous costs of default following the quantitative literature of sovereign debt. To account for liquidity risk, we...

The Drift Burst Hypothesis postulates the existence of short-lived locally explosive trends in the price paths of financial assets. The recent US equity and Treasury flash crashes can be viewed as two high profile manifestations of such dynamics, but we argue that drift bursts of varying magnitude...

We analyze strategic experimentation in which information arrives through fully revealing, publicly observable “breakdowns.” When actions are hidden, there exists a unique symmetric equilibrium that involves randomization over stopping times. With two players, this is the unique equilibrium....

We prove that if $f$ is a positive $C^2$ function on a convex compact set $X$ then it becomes strongly convex when multiplied by $(1+|x|^2)^N$ with $N$ large enough. For $f$ polynomial we give an explicit estimate for $N$, which depends on the size of the coefficients of $f$ and on the lower bound...

Dans cet exposé je discuterai les conditions nécessaires d’optimalité (principe de maximum et les relations de sensibilité) pour les problèmes de contrôle à l’horizon infini impliquant un coût avec ou sans le facteur d’actualisation. Dans ce cadre les difficultés majeures sont liées au choix des...

We measure the persuasive effects of slanted news and tastes for like-minded news, exploiting cable channel positions as exogenous shifters of cable news viewership. Channel positions do not correlate with demographics that predict viewership and voting, nor with local satellite viewership. We...

This paper analyzes the effect of the tick size on market quality variables with a view of making specific predictions of what to expect from the SEC pilot program on tick size. We make three analyses with two different datasets. One dataset is a cross-section of over 2000 assets selected from the...
