This paper applies real options theory to establish an overseas oil investment evaluation model that is based on Monte Carlo simulation and is solved by the Least Squares Monte-Carlo method. To better reflect the reality of overseas oil investment, our model has incorporated not only the uncertainties of oil price and investment cost but also the uncertainties of exchange rate and investment en...

Wilkie (1999) proved a “theorem of the complement” which implies that in order to establish the o-minimality of an expansion of R with C∞ functions it suffices to obtain uniform (in the parameters) bounds on the number of connected components of quantifier free definable sets. He deduced that any expansion of R with a family of Pfaffian functions is o-minimal. We prove an effective version of W...

Household investment, that is investment in consumer durables and housing, leads non-residential fixed investment over the U.S. business cycle. This observation represents a potent challenge to real business cycle (RBC) theory. First of all the theory has been unable to account for it. In addition, research suggests the observation is driven by monetary shocks, supporting the view that these sh...

we give further results for perron-frobenius theory on the numericalrange of real matrices and some other results generalized from nonnegative matricesto real matrices. we indicate two techniques for establishing the main theorem ofperron and frobenius on the numerical range. in the rst method, we use acorresponding version of wielandt's lemma. the second technique involves graphtheory.

This study aims at determining the personality traits and investment patterns in the stock market and presenting the pattern with a behavioral finance approach. This is an applied, descriptive- survey, and cross-sectional study. The statistical population includes real investors in the Tehran Stock Exchange. The required information was collected using questionnaire and was analyzed using SPSS ...

In the 1990’s, the World Agroforestry Centre (ICRAF) initiated a domestication programme of indigenous fruit trees (IFTs) in Southern Africa to increase farmhousehold income through farmer-led tree planting and thus conserve bio-diversity. From the farmer's point of view planting domesticated IFTs is an investment under uncertainty and irreversibility. As timing of planting is flexible, real op...
