    Flexible work arrangements and precautionary behaviour : theory and experimental evidence
    (2020) Rostam-Afschar, Davud; Orland, Andreas
    In the past years, work time in many industries has become increasingly flexible opening up a new channel for intertemporal substitution. To study this, we set up a two-period model with wage uncertainty. This extends the standard saving model by allowing a worker to allocate a fixed time budget between two work shifts or to save. To test the existence of these channels, we conduct laboratory consumption/saving experiments. A novel feature of our experiments is that we tie them to a real-effort style task. In four treatments, we turn on and off the two channels for consumption smoothing: saving and time allocation. Our four main findings are: (i) subjects exercise more effort under certainty than under risk; (ii) savings are strictly positive for at least 85 percent of subjects (iii) a majority of subjects uses time allocation to smooth consumption; (iv) saving and time shifting are substitutes, though not perfect substitutes.

    How important is precautionary labor supply?
    (2016) Schmitz, Sebastian; Rostam-Afschar, Davud; Jessen, Robin
    We quantify the importance of precautionary labor supply using data from the German Socio-Economic Panel (SOEP) for 2001-2012. We estimate dynamic labor supply equations augmented with a measure of wage risk. Our results show that married men choose about 2.5% of their hours of work or one week per year on average to shield against unpredictable wage shocks. This implies that about 26% of precautionary savings are due to precautionary labor supply. If self-employed faced the same wage risk as the median civil servant, their hours of work would reduce by 4%.
