In this paper, we propose a binomial approach to modeling sequential R&D investments. More specifically, we present a compound real options approach, simplifying the existing valuation methodology. Based upon the same set of assumptions as prior models, we show that the number of computational...

This paper provides an overview of the status quo in socially responsible investing (SRI) literature. We outline motives, history, and current best practice of SRI. We also provide a thorough analysis of a wide set of studies that cover two key topics in this field: the first research objective...

This article examines the determinants of the optimal percentage that private investors seek to invest in a socially responsible (SR) way when forming their portfolio. By conducting a global online survey in English, German and French, we find indications that it is sufficient for the majority...

In this paper, we present the results of an online questionnaire among private German mutual fund investors. In an exploratory nature, we empirically analyze the differences between three groups: sustainable investors, conventional investors that are either generally interested or those that are...

I extend and generalize the work of Kruschwitz and Löffler (BuR-Business Research 2(2):171-178, 2009). I find that, with a zero risk-free rate, the implicit price of capital gains tax payments is zero. I provide conditions in stochastic discount factor language when a capital gains tax has no...

With a unique data set from New Zealand which allows us to assign each bet to individual bettors, we analyze the impact of experience on behavior and success in non-parimutuel (fixed odds) sports betting markets. We find that experienced bettors bet more on favorites than inexperienced bettors...

The information contained in investor sentiment has up to now hardly been used for portfolio optimization, although theoretical works demonstrate that it should not be neglected and it has already been shown to contain exploitable information on future returns and volatility. Employing the...

The existence of ambiguity presents a challenge to decision-makers as it eliminates the ability to apply standard optimization approaches, such as those based on calculating the objective expected values of alternative actions. In reality, ambiguity arises in most strategically important...
