Is the investment-uncertainty relationship non-linear? an emperical [i.e. empirical] analysis for the Netherlands

We examine the investment-uncertainty relationship for a panel of Dutch manufacturing firms. The system generalised method of moments (GMM) estimates suggests that the effect of uncertainty on investment is non-linear: for low levels of uncertainty an increase in uncertainty has a positive effect on investment, whereas for high levels of uncertainty an increase in uncertainty lowers investment. This result is in line with a number of theoretical studies, but has never been demonstrated empirically.
