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...

We present an optimal investment theorem for a currency exchange model with random and possibly discontinuous proportional transaction costs. The investor’s preferences are represented by a multivariate utility function, allowing for simultaneous consumption of any prescribed selection of the...

Leland’s approach to the hedging of derivatives under proportional transaction costs is based on an approximate replication of the European-type contingent claim V T using the classical Black–Scholes formula with a suitably enlarged volatility. The formal mathematical framework is a scheme...

In contrast with the classical models of frictionless financial markets, market models with proportional transaction costs, even satisfying usual no-arbitrage properties, may admit arbitrage opportunities of the second kind. This means that there are self-financing portfolios with initial...

This study reconsiders the problem of hedging a liability by a portfolio made of a riskless asset and an underlying (underlying).

This paper examines how credit derivatives have changed the construction of an efficient portfolio. Credit derivatives provide a way of gaining exposure to credit risk alone, to the exclusion of interest rate risk. They also permit a relatively easy use of leverage. We examine two types of...

L’objectif du papier est de fournir une première analyse exploratoire des déterminants macroéconomiques des primes de taux. L’optique retenue est celle des choix de portefeuille opérés par les banques à leur actif. Dès lors, les primes de taux sont calculées en comparant un actif...

Cet article se propose d’étudier l’influence de l’âge sur la composition des patrimoines, notamment sur la détention d’actifs risqués. En effet, une hypothèse souvent avancée est que, plus l’horizon de vie se raccourcit, plus la détention d’actifs risqués devrait se réduire....

This paper contributes to the resolution of the rights offer paradox, using a database of French SEOs. We first document higher direct flotation costs, but also improved stock market liquidity after public offerings and standby rights relative to uninsured rights. We find that blockholder...
