This dissertation focuses on the link between labour market institutions and precautionary savings. It is evaluated whether private households react to changes in social insurance provision such as the income replacement in case of unemployment by increased savings for precautionary reasons. The dissertation consists of three self-contained chapters, each focusing on slightly different aspects of the topic. The first chapter titled "Precautionary saving and the (in)stability of subjective

... gs uncertainty" empirically looks at the influence of future income uncertainty on household saving behavior. Numerous cross-section studies on precautionary saving use subjective expectations regarding the income variance one year ahead as a proxy for income uncertainty. Using such proxies observed only at one point in time, however, may give rise to biased estimates for precautionary wealth if expectations are not stable over time. Survey data from the Dutch DNB Household Survey suggest that subjective future income distributions are not stable over the mid-term. Moreover, in this study I contrast estimates of precautionary wealth using the variation coefficient observed at one point in time with those using a simple mid-term average. Estimates of precautionary wealth based on the average are about 40% to 80% higher than the estimates using the variation coefficient observed only once. In addition to that, wealth accumulation for precautionary reasons is estimated for different parts of the income distribution. The share of precautionary wealth is highest for households at the center of the income distribution. By linking saving behaviour with unemployment insurance, the following chapters then shed some light on an issue that has largely been neglected in the literature on labour market institutions so far. Whereas the third chapter models the relevance of unemployment insurance for income uncertainty and intertemporal decision making during institutional reform processes, chapter 4 seeks to establish empirically a rela [...]
