【本期主题】Investment under Uncertaintyand the Value of Real and Financial Flexibility

We develop a model of investment timing under uncertaintyfor a financially constrained firm. Facing external financing costs, thefirm prefers to fund its investment through internal funds, so that thefirm’s optimal investment policy and value depend on both its earningsfundamentals and liquidity holdings. We show that financial constraintssignificantly alter the standard real options results, with the financialflexibility conferred by internal funds acting as a complement, and at timesas a substitute, to the real flexibility given by the optimal timing ofinvestment. We show that: 1) the investment hurdle is highly nonlinear andnon-monotonic in the firm’s internal funds; 2) in contrast to predictionsimplied by standard corporate savings models, a financially constrained firmmay behave in a risk seeking sense (and thus firm value may be convex inliquidity) due to the interaction between financial and real(growth/abandonment) flexibility; 3) with multiple rounds of growth options,a value-maximizing financially constrained firm may choose to over-investvia accelerated investment timing in earlier stages in order to mitigateunder-investment problems in later stages.
