Using audit trail data for a sample of NYSE firms, we show that medium size trades are associated with a disproportionately large cumulative stock price change relative to their proportion of all trades and volume. This result is consistent with the predictions of the stealth- trading hypothesis...

The purpose of this paper is to analyse the relationship between the corporate governance system and technical efficiency in Italian manufacturing. We use a non-parametric frontier technique (DEA) to derive technical efficiency measures for a sample of Italian firms taken from 9 manufacturing...

Central bank spending on the operation of inter-bank funds transfer systems may range from below one million to nearly a billion US dollars annually. This paper examines how such costs are incurred and recovered to pursue payment systems efficiency in different countries and under alternative...

The distributional form of financial asset returns has important implications for the theoretical and empirical analyses in economics and finance. It is now a well-established fact that financial return distributions are empirically nonstationary, both in the weak and the strong sense. One first...

Dans un article d’octobre 2001, Jensen souligne les limites opérationnelles de la théorie de la maximisation de la valeur et de la théorie des parties prenantes (Stakeholder theory). La complémentarité entre ces théories vient de l’affirmation que le bien être collectif n’est...

A valuation model is presented for options on stocks for which Black- Scholes arbitrage does not entirely eliminate risk. The price dynamics of a portfolio of options and the underlying security is quantified by requiring that the excess reward-to-risk ratio of the portfolio be identical to that...

We examine firm managers' incentives to commit fraud in a model where firms seek funding from investors and investors can monitor firms at a cost in order to get more precise information about firm prospects. We show that fraud incentives are highest when business conditions are good, but not...

We extend the credit risk valuation framework introduced by Gatfaoui (2003) to stochastic volatility models. We state a general setting for valuing risky debt in the light of systematic risk and idiosyncratic risk, which are known to affect each risky asset in the financial market. The option...

Our methodology of 'complete identification,' using simple algebraic geometry, throws new light on the continued commitment of Galton's Error in finance and the resulting misinformation of investors. Mutual funds conventionally advertise their relative systematic market risk, or 'betas,' to...

In recent years, one area of growing concern in corporate governance is the accounting and transfer of risk using special purpose entities (or trusts). Such entities are used widely in issuing asset-backed securities. This paper provides an overview of the asset-backed securities market, and...
