We prove a general version of the super-replication theorem, which applies to Kabanov’s model of foreign exchange markets under proportional transaction costs. The market is described by a matrix-valued càdlàg bid-ask process $$(\Pi_t)_{t\in [0,T]}$$ evolving in continuous time. We propose a...

Testing for normality is of paramount importance in many areas of science since the Gaussian distribution is a key hypothesis in many models. As the use of semi–moments is increasing in physics, economics or finance, often to judge the distributional properties of a given sample, we propose a...

L'objectif de cet article est de confronter deux mesures classiques du risque de défaillance de l'émetteur, la notation et l'écart de rentabilité. La première est attribuée par des agences spécialisées dans cette activité (Standard and Poor's et Moody's) alors que la seconde résulte du...

The problem of fair pricing of contingent claims is well understood in the contex of an arbitrage free, complete financial market, with perfect information : the so-called arbitrage approach permits to construct a unique valuation operator compatible with observed price rocesses. In the more...

This article deals with the time-series variation in average sin stock returns – returns on publicly-traded companies involved in producing tobacco, alcohol, and gaming. Next to nothing has been written about this class of stocks, especially on the European stock market. The hypothesis I...

This article examines how the inception of an ETF market impacts several dimensions of the liquidity of the ETF-underlying-index stocks. In contrast with previous research, our evidence is based on an ETF market where liquidity providers (LPs) act as market makers. We find that: (1) the market...

In this study, we test the three factor model of Fama and French and the Characteristic Model of Daniel and Titman (1997) on The French Stock Market over July 1976 to June 2001 period. Stocks are ranked by size and book to market ratios and then by ex-ante HML, SMB or Mkt loadings. The...
