Seminars in Statistics Ilya Molchanov (University of Bern)

Symmetries of probability distributions, their geometric meaning and financial applications The talk starts with the known put-call symmetry property and its application to semi-static hedging of barrier options. Then it is explained how to interpret this property geometrically and extend it in various ways, most importantly for the multivariate (multiasset) case that would correspond to…

"Discrimination in labour markets: An experimental analysis" Abstract: This study highlights that discrimination can be pervasive on the labor market also in the lack of quality differences between different categories and if employers with unbiased intentions strive for high quality workers. We tested experimentally the hypotheses that (i) high aspiration levels of firms and (ii)…

Seminars in Economics Fernando Vega-Redondo (EUI)

"Social networks and the process of globalization" Abstract We propose a stylised dynamic model to understand the role of social networks in the phenomenon we call "globalization." This term refers to the process by which even agents who are geographically far apart come to interact, thus overcoming what would otherwise be a fast saturation of…

"Simple Markov-Perfect Industry Dynamics" Abstract This paper develops a tractable model for the computational and empirical analysis of infinite-horizon oligopoly dynamics. It features aggregate demand uncertainty, sunk entry costs, stochastic idiosyncratic technological progress, and irreversible exit. We develop an algorithm for computing a symmetric Markov-perfect equilibrium quickly by finding the fixed points to a finite…

"Inference for Best Linear Approximations to Set Identified Functions" Abstract: This paper provides inference methods for best linear approximations to functions which are known to lie within a band. It extends the partial identification literature by allowing the upper and lower functions defining the band to be any functions, including ones carrying an index, which…

"On the Efficiency of Partial Information in Elections" We study the relation between the electorate’s information about candidates’ policy platforms during an election, and the subsequent provision of inefficient local publicgoods (pork) by the elected government. More information does not lead to better outcomes. We show that the efficient outcome in which no candidate proposes…

"Price as a signal of product quality: experimental evidence from wine tastings" Abstract:We study the determinants of the choice between wines in wine tasting experiments where about 200 nonprofessional tasters were asked to indicate which one of the tasted wines they preferred and which one they would buy. In addition to actually tasting several wines, which differ in terms…

Seminars in Statistics Sergio Bacallado (Stanford University)

A Bayesian analysis of reversible time series with an uncertain length of memory We propose a Bayesian analysis of reversible time series using a Probabilistic Suffix Automaton (PSA) model. We show that PSAs have a representation as higher-order Markov chains, and that the class of reversible PSAs generalize reversible variable-order Markov chains. The analysis uses…

"Estimating the Elasticity of Intertemporal Substitution: Results from an International Panel"
