This short note is aimed to open discussion. Asset pricing models assume capital markets are competitive, but then my questions were: Why would a diversified investor be willing to accept a supposedly lower equilibrium risk adjusted rate of return in emerging markets (like Argentina), that the...

The link between investor sentiment and asset valuation is at the center of a long-running debate in behavioral finance. Using a new composite sentiment indicator, we show that the conventional risk does not explain the abnormal returns of portfolios most sensitive to the sentiment factor. Our...

Tax saving´s valuation is crucial for discounted cash flow valuation and WACC estimation. There is an ongoing debate about the appropriate discount rate for tax savings under CAPM approach. On this paper we evaluate tax savings from a contingent claim approach in order to establish a framework...

In investment appraisal, uncertainty can be managed through intervals or fuzzy numbers because the arithmetical properties and the extension principle are well established and can be successfully applied in a rigorous way. We apply interval and fuzzy numbers to the Average Internal Rate of...

This paper expands Teichroew, Robichek and Montalbano's (TRM) (1965a, b) rate-of-return model into a complete and general model of economic profitability for investment decision-making. Specifically, TRM's assumptions are relaxed and a project rate of return is derived, expressing the project's...

This note specifies some results found in [Magni 2010. The Engineering Economists, 55(2), 150-180] where the Average Internal Rate of Return (AIRR) is presented, which overcome all the IRR difficulties. In particular, the AIRR approach enables to prove that (1) a project is not uniquely...

The recent notion of Average Internal Rate of Return (AIRR) [Magni 2010, The Engineering Economist, 55(2), 150-180] completely solves the long-standing problem of the internal rate of return (IRR). While the AIRR is a return measure, this paper presents a cash-flow measure, namely the ratio of...

The paper describes and analyzes the application of the capital asset pricing model (CAPM) and the single-index model on the Zagreb stock exchange during the drop in the total trade turnover, and mostly in the trade of equity securities. This model shows through the analysis techniques used to...
