The study of memory for event duration in pigeons has, for the most part, centered on an unusual behavioral phenomenon and an interesting theoretical explanation for it. A typical experiment on memory for event duration involves trials initiated by a sample stimulus that is either short or long in duration (e.g., 2 vs. 10 sec of houselight) and that is later followed by the simultaneous present...

T recent financial crisis highlights the importance of market crashes and the subsequent market illiquidity for optimal portfolio selection. We propose a tractable and flexible portfolio choice model where market crashes can trigger switching into another regime with a different investment opportunity set. We characterize the optimal trading strategy in terms of coupled integro-differential equ...

To have a real option means to have the possibility for a certain period to either choose for or against something, without binding oneself up front. The real option rule is that one should invest today only if the net present value is high enough to compensate for giving up the value of the option to wait. Because the option to invest loses its value when the investment is irreversibly made, t...

In this paper, we investigate the impact of inaccurate forecasting on the coordination of distributed investment decisions. In particular, by setting up a computational multi-agent model of a stylized firm, we investigate the case of investment opportunities that are mutually carried out by organizational departments. The forecasts of concern pertain to the initial amount of money necessary to ...

We examine the problem of a risk-neutral investor who has to choose among two alternative projects of different scales under output price uncertainty. We show that as soon as investment in the smaller scale project is sometimes optimal, the optimal investment strategy is not a trigger strategy and the optimal investment region is dichotomous. Whenever the investor has the opportunity to switch ...

While there are a number of finance methods (fundamental analysis, technical analysis, contrarians’ theory, risks management, etc) used in stock markets to help make investment decisions, they have different strengths and weakness. It is observed that these different finance methods are not being integrated by existing technologies in a systematic way, thus their performance for identifying inv...
