In this paper we perform a meta-analysis on empirical estimates of the impact between investment and uncertainty. Since the outcomes of primary studies are largely incomparable with respect to the magnitude of the effect, our analysis focuses on the direction and statistical significance of the...

We study a two-stage R&D project with an abandonment option. Two types of uncertainty influence the decision to start R&D. Demand uncertainty is modelled as a lottery between a proportional increase and decrease in demand. Technical uncertainty is modelled as a lottery between a decrease and...

This article discusses the effects of an asymmetric tax scheme on incremental and sequential investment strategies. The tax base is equal to the firm s return, net of an imputation rate. When the firm s return is less than this rate, however, no tax refunds are allowed. This scheme is neutral...

In this paper we offer an analysis of the effects of uncertainty about future tax policy on irreversible investment. The main message of the paper is that investment is not much affected by the degreee of tax policy uncertainty. This is true regardless of whether random tax changes are...

We present a model of firm investment under uncertainty and partial irreversibility in which uncertainty is represented by a jump diffusion. This allows to represent both the continuous Gaussian volatility and the discontinuous uncertainty related to information arrival, sudden changes and large...

This paper combines the recent game theoretic approach of endogenous timing of entry to herding models with a macroeconomic model of investment cycles. The integrated description embodies the qualitative results of the myopic herding model in a medium run investment objective of smoothing the...
