We derive an estimator for Black-Scholes-Merton implied volatility that, when compared to the familiar Corrado & Miller [JBaF, 1996] estimator, has substantially higher approximation accuracy and extends over a wider region of moneyness.

In this paper we explore the theoretical and empirical problems of estimating average (excess) return and risk of US equities over various holding periods and sample periods. Our findings are relevant for performance evaluation, for estimating the historical equity risk premium, and for...

Aside from the aggregated information provided by price and quantity indexes, there is growing interest in index decompositions that reveal the contribution of each index component to overall index change. In this paper, we derive a “natural†decomposition of the Fisher price index...

Large institutional investors allocate their funds over a number of classes (e.g. equity, fixed income and real estate), various geographical regions and different industries. In practice, these allocation decisions are usually made in a hierarchical (top-down), consecutive way. At the higher...

We present an analysis of the performance of the DAX, German's major stock market index, over the last two years. Our analysis is broader than conventional benchmark approaches because we study the properties of all feasible portfolios, i.e. portfolios composed given the same investment...

In this paper we present and illustrate using real-life data a framework for managing an investment portfolio in which the investment opportunities are described in terms of a set of attributes and part of this set is intended to capture the effects on society. Here we link with the emerging...

Most financial-economic decisions are made consciously, with a clear and constant drive to ???good???, ???better??? or even ???optimal??? decisions. Nevertheless, many decisions in practice do not earn these qualifications, despite the availability of financial economic theory, decision sciences...

For people working in finance, either in academia or in practice or in both, the combination of ?finance? and ?multiple criteria? is not obvious. However, we believe that many of the tools developed in the field of MCDM can contribute both to the quality of the financial economic decision making...

In line with romantic views on leadership, leaders are traditionally held responsible for any kind of ethical misconduct in organizations. Through explicating the influence of followers on their leaders' (unethical) decision-making, we aim to add some nuances to this view with the present...
