TY - JOUR TI - Pricing real options under the constant elasticity of variance diffusion T2 - Journal of Futures Markets VL - 31 IS - 3 AU - Dias, J. C. AU - Nunes, J. P. PY - 2011 SP - 230-250 SN - 0270-7314 DO - 10.1002/fut.20468 UR - http://onlinelibrary.wiley.com/doi/10.1002/fut.20468/abstract AB - Much of the work on real options assumes that the underlying state variable follows a geometric Brownian motion with constant volatility. This paper uses a more general assumption for the state variable process that better captures the empirical regularities found in commodity markets. We use the constant elasticity of variance diffusion, where volatility is a function of underlying asset prices, and we provide analytic solutions for perpetual American options. We show that a firm that uses the standard lognormal assumption is exposed to significant errors of analysis, which may lead to nonoptimal investment and disinvestment decisions. ER -
