Incorporating Risk Preferences into Real Options Models
نویسنده
چکیده
This paper develops a framework to link the expected utility analysis to real options models in order to capture the joint effects of risk aversion and irreversibility associated with real investments. It aims at modifying the theory of investment under uncertainty by incorporating decision makers’ risk preferences and allows explicitly analyzing the impacts of risk aversion, uncertainty and irreversibility on decisions such as investment and resource allocations. It addresses the shortcomings of the commonly used expected utility and investment under uncertainty models by generalizing the theory of irreversible investment under uncertainty by allowing for risk-averse investors. We found that uncertainty, irreversibility and risk aversion are important determinants of the optimal timing of irreversible decisions. Ignoring risk preferences in real options models would lead to over or underestimation of magnitude of investments. Key Word: expected utility, investment under uncertainty, irreversibility, real options, risk aversion. JEL Classification: D81, G1

In this paper, we try to develop and modify the basic model of the consumption-based capital asset pricing model by adding the growth in real money balances rate as a risk factor in the household's utility function as (M-CCAPM). For this purpose, two forms of utility function with constant relative risk aversion (CRRA) preferences and recursive preferences have been used such that M1 and M2 are...

Making Invasion Models Useful for Decision Makers: Incorporating Uncertainty, Knowledge Gaps and Decision- making Preferences
Uncertainty is inherent in model-based forecasts of ecological invasions. In this chapter, we explore how the perceptions of that uncertainty can be incorporated into the pest risk assessment process. Uncertainty changes a decision maker’s perceptions of risk; therefore, the direct incorporation of uncertainty may provide a more appropriate depiction of risk. Our methodology borrows basic conce...

Investments in technology create a large amount of capital investments by major companies. Assessing such investment projects is identified as critical to the efficient assignment of resources. Viewing investment projects as real options, this paper expands a method for assessing technology investment decisions in the linkage existence of uncertainty and competition. It combines the game-theore...

We describe methods for incorporating the effects of insects and diseases on coniferous forests into forest simulation models and discuss options for including this capability in the modeling work of the Interior Northwest Landscape Analysis System (INLAS) project. Insects and diseases are major disturbance agents in forested ecosystems in the Western United States, and over time, are responsib...
