abstract       background and objectives: more candida albicans strains are reported resistant to fluconazole in patients with aids, cancer and organ recipients. fluconazole resistance can be attributed to changes in pathways of sterol biosynthesis, mutation in or overexpression of erg11 and the expression of cdr1, cdr2, and mdr1. this study aimed to compare the expression of cdr1, cdr2, and md...

By mixing concepts from both game theoretic analysis and real options theory, an investment decision in a competitive market can be seen as a “game” between firms, as firms implicitly take into account other firms’ reactions to their own investment actions. We review several real option game models, suggesting which critical problems have been “solved” by considering game theory, and which sign...

After 30 years of discussion and research, the academic community has established a complete theoretical system of real options and provided an excellent framework for the use of real options theory in the investment appraisal of high-tech projects. An option is an entitlement without any obligation and it has been used to describe a variety of management decisions in business investment. The d...

This survey paper provides an overview of real options, in particular the connection with financial options, valuation methods (analytical methods vs numerical methods based on simulation, lattice approximations to stochastic processes and finite-difference methods) and a wide array of application areas, from R&D to operations management to renewable energy project selection. 1 Real Options vs ...

I introduce a strategic seller to a standard model of real options. A privately informed seller, such as a startup, tries to court a forward-looking buyer, such as a venture capitalist. The buyer learns gradually about the seller’s quality, high or low, through exogenous news and can “adopt” the seller at any time. The seller pays a flow cost but can exit or privately upgrade its quality at any...

This paper revisits Williams (1997) on the effect of net rental price, asset quality and variable investment costs on the asset redevelopment decision. This paper develops a quasi-analytical method for solving the generalised real renovation option problem by treating the investment cost as having both a variable and a fixed element and then extends the analysis for the case where both the net ...
