In some recent papers, such as Elliott & van der Hoek, Hu & Öksendal, a fractional Black-Scholes model have been proposed as an improvement of the classical Black-Scholes model. Common to these fractional Black-Scholes models, is that the driving Brownian motion is replaced by a fractional...

In organizations, ideas are often delegated for evaluation as a means of efficiently aggregating multiple information signals. However, those who delegate often find it impossible to separate the evaluation of the ideas they delegate from the evaluation of abilities of those delegated the task...

One of the debates in the capital budgeting model selection is between the free cash flow and DCF methods. In this paper an attempt is made to compare SVA against NPV model based on Monte Carlo simulations. Accordingly, NPV is found less sensitive to value driver variations and has got higher...

The survey findings indicate the existence of gap between theory and practice of capital budgeting. Standard appraisal methods have shown a wider project value discrepancy, which is beyond and above the contingency limit. In addition, the research has found the growing trend in the use of value...

The poor performance often attributed to many public employment services may be explained in part by a delegation problem between the central office and local job centers. In markets characterized by frictions, job centers function as match-makers, linking job seekers with relevant vacancies....

In capital budgeting problems future cash flows are discounted using the expected one period returns of the investment. In this paper we establish a theory that relates this approach to the assumption that markets are free of arbitrage. Our goal is to uncover implicit assumptions on the set of...
