In a mean variance framework, we analyse risk taking in the presence of a (possibly) dependent background risk, exemplified in a linear portfolio selection problem. We first characterise the comparative statics of changes in the distribution and dependence structure of the background risk. For...

When based on perceived rather than on objective income distributions, the Meltzer-Richards hypothesis and the POUM hypothesis work quite well empirically: there exists a positive link between perceived inequality or perceived upward mobility and the extent of redistribution in democratic...

Since Adam Smith, most economists have held that a professional army is superior to a conscript army, thanks to benefitting from comparative advantage and specialization. We summarize recent literature on the benefits and costs of the military draft, with special emphasis on its dynamic effects...

Government-run entities are often more labor-intensive than private companies, even with identical production technologies. This need not imply slack in the public sector, but may reflect a wage tax advantage, stemming from the fact that government entities (partly) pay their taxes to...

We analyze the interplay of group identity and inter-group conflict in a contest where each of two conflicting groups can develop either a group or an individualistic identity. Contest structures impact on the adoption of identities which themselves influence behavior in the contest. We show the...

In an occupational choice framework individuals can either become entrepreneurs (risky income) or employed workers (safe income). Their choice is affected by the design of the pension system which discriminates between entrepreneurs and workers. We explore the comparative statics of several...

From the expected-utility approach, relative risk aversion being smaller than one and relative prudence being smaller than two emerge as preference restrictions that fully determine the optimal responses of decisions under uncertainty to certain shifts in probability distributions. We...

We show that, if an individual's utility function exhibits a degree of relative temperance smaller than one, the individual will react, in a plausible way, to each of three common shifts in the stochastic distribution of his wealth, namely to FSD shifts, mean-preserving spreads and increases in...
