This paper shows that, in the temporal model of Eeckhoudt et al. (2012), prudence alone is sufficient to obtain a precautionary effort. Moreover, our conclusions relax the assumption of the convexity of loss probability. We further analyze the effect of the introduction or deterioration of background risks on precautionary effort in different settings.
