The price of an option should reflect the average value that a buyer receives for it, and also a risk premium. This report describes an empirical study for analysing these factors as a graphical and quantitative manner. The analysis focuses on the average difference between the price option and...

This report presents and proposes several methods to improve the capacity of generalization of the learning algorithms in a context of financial decision-making. These methods, overall, aim at controlling the capacity of the learning algorithms in order to limit the problem of the over-training,...

The non-parametric modelization of the stock options and other derivatives generated an increased interest over the past years. The goal of this paper is to predict the market price of an option from the same information as needed by the Black-Scholes formula. This is a continuation of more...

This paper introduces the minimum entropy regularizer for learning from partial labels. This learning problem encompasses the semi-supervised setting, where a decision rule is to be learned from labeled and unlabeled examples. The minimum entropy regularizer applies to diagnosis models, i.e....

We aim at modelling fat-tailed densities whose distributions are unknown but are potentially asymmetric. In this context, the standard normality assumption is not appropriate.In order to make as few distributional assumptions as possible, we use a non-parametric algorithm to model the center of...

Prior work on option pricing falls mostly in two categories: it either relies on strong distributional or economical assumptions, or it tries to mimic the Black-Scholes formula through statistical models, trained to fit today's market price based on information available today. The work...

This document presents the StarLink corn case in four sections. The StarLink corn had been approved by the Environmental Protection Agency (EPA) in 1998 for use only in animal food and other non-alimentary industrial products, due to the potential human allergy reactions. But in September 2000,...

Most of the analyses of small firms' decision to seek outside equity financing and the conditions thereof have concerned private firms. Knowledge of the risk and return of entrepreneurial ventures for outside investors is consequently limited. This paper attempts to fill this gap by examining...

We provide the first empirical application of a new approach proposed by Lee (2007) to estimate peer effects in a linear-in-means model. This approach allows to control for group-level unobservables and to solve the reflection problem. We investigate peer effects in student achievement in...
