Optimal Investment and Financial Strategies under Tax-Rate Uncertainty

In this paper, we apply a real-option model to study the effects of tax-rate uncertainty on a firm’s decision. In doing so, we depart from the relevant literature, which focuses on fully equity-financed investment projects. By letting a representative firm borrow optimally, we show that debt finance not only encourages investment activities but can also substantially mitigate the effect of tax-rate uncertainty on investment timing.
