Human subjects decide when to sink a fixed cost "C" to seize an irreversible investment opportunity whose value "V" is governed by Brownian motion. The optimal policy is to invest when "V" first crosses a threshold "V"* = (1 + "w"*)"C", where the wait option premium "w"* depends on drift,...

Human subjects decide when to sink a fixed cost C to seize an irreversible investment opportunity whose value V is governed by Brownian motion. The optimal policy is to invest when V first crosses a threshold V* = (1 + w*)C, where the wait option premium w* depends on drift, volatility, and...
