- While there is ample evidence of a society-wide cooperation norm, it is not as clear who upholds this norm. In the present paper, we investigate whether there are gender differences with respect to norm enforcement. We let 1403 subjects play games of punishment and reward, individually or in groups with varying gender composition. Broadly, the results indicate that there are no clear gender differences: men are about as inclined as women to punish norm-breakers. However, behavior is context-dependent: men acting among other men are less inclined to uphold a cooperation norm than are women, or men in gender-mixed groups.

A Continuous Theory of Income Insurance
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In this paper we treat an individual’s health as a continuous variable, in contrast to the traditional literature on income insurance, where it is regularly treated as a binary variable. This is not a minor technical matter; in fact, a continuous treatment of an individual’s health sheds new light on the role and functioning of income insurance and makes it possible to capture a number of real-world phenomena that are not easily captured in binary models. In particular, moral hazard is not regarded as outright fraud, but as a gradual adjustment of the willingness to go to work when income insurance is available. Further, the model can easily encompass phenomena such as administrative rejection of claims and the role of social norms. It also gives a rich view of the desirability of insurance in the first place.

Vetenskapliga sanningar och feministiska myter
- 2011
-
Ingår i: Ekonomisk Debatt. - 0345-2646. ; 39, s. 5-13
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- I en nyligen publicerad bok presenterar och avfärdar samhällsdebattören Pär Ström vad han betraktar som sex olika "feministiska myter". I denna artikel granskas framställningen. Vi finner att den på en rad punkter vilar på en mycket svag empirisk grund. Pär Ström använder sig av statistik och citat på ett selektivt vis och verkligheten är mer komplicerad än vad han vill ge sken av.

Studies in Saving under Uncertainty
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis consists of three essays.In Precautionary Saving under Correlated Risk, I show that the sign of the correlation between the random variables might determine whether saving increases or decreases when risk is introduced. Precautionary saving is thus not confirmed. In the second part of this chapter, the consumer must also allocate her saving between an insurance and an interest-bearing asset. It is shown that switching the sign of correlation changes the optimal insurance ratio and probably also optimal saving.Saving and Portfolio Choice by Mutually Altruistic Consumers treats the effects of mutual altruism between two individuals. Compared to the Utilitarian social optimum there is, on the one hand, a tendency to higher saving and lower risk share resulting from the higher uncertainty of future income in the Nash equilibrium. On the other hand, there is a tendency to lower saving and higher risk share arising from the possibility of a free ride on the generosity of others, named "Samaritan's Dilemma". Analytically, it was not possible to determine the size or the direction of divergences in the choice variables. Numerical examples show that the effect of the Samaritan's Dilemma outweighs the effect of the greater uncertainty of future income in the Nash equilibrium. However, the divergence in saving between the two solutions is rather small.In the literature, uncertain lifetime has been used to explain both unexpectedly low and unexpectedly high saving by the elderly. In The Effect of Uncertain Lifetime on the Saving of the Elderly, risk is introduced into the remaining lifetime and the consequences of a background risk are investigated. Introducing uncertain lifetime into the certainty model results in a slower decumulation of wealth from the date of retirement. On the contrary, introducing uncertain lifetime into a model with uncertain investment income results in a swifter decumulation and an earlier depletion of wealth.
