Lost in State Space: Are Preferences Stable?

We use field experiments to examine the temporal stability of risk preferences. Over a 17-month period, we elicited risk preferences from subjects chosen to be representative of the adult Danish population. During this period we revisited many of these subjects and repeated a risk aversion elicitation task. We find some variation in risk attitudes over time, but we do not detect a general tendency for risk attitudes to increase or decrease over a 17-month span. The results also suggest that risk preferences are state contingent with respect to personal finances.

Gender, Competitiveness, and Socialization at a Young Age: Evidence From a Matrilineal and a Patriarchal Society

Recent literature presents evidence that men are more competitively inclined than women. Since top-level careers usually require competitiveness, competitiveness differences provide an explanation for gender gaps in wages and differences in occupational choice. A natural question is whether women are born less competitive or whether they become so through the process of socialization. To pinpoint when in the socialization process the difference arises, we compare the competitiveness of children in matrilineal and patriarchal societies. We find that while there is no difference at any age in the matrilineal society, girls become less competitive around puberty in the patriarchal society.

Risk aversion in game shows

We review the use of behavior from television game shows to infer risk attitudes. These shows provide evidence when contestants are making decisions over very large stakes, and in a replicated, structured way. Inferences are generally confounded by the subjective assessment of skill in some games, and the dynamic nature of the task in most games. We consider the game shows Card Sharks, Jeopardy!, Lingo, and finally Deal Or No Deal. We provide a detailed case study of the analyses of Deal Or No Deal, since it is suitable for inference about risk attitudes and has attracted considerable attention.

Inattention and Inertia in Household Finance: Evidence from the Danish Mortgage Market

This paper studies inattention to mortgage refinancing incentives among Danish households. Danish data are particularly suitable for this purpose because there are minimal barriers to refinancing, yet many borrowers fail to refinance optimally, and the characteristics of these borrowers can be accurately measured. The paper estimates a mixture model of household refinancing types in which household characteristics affect both inattention (a low proportion of rational refinancers) and residual inertia (a low probability that fully inattentive households refinance). Many characteristics move inattention and inertia in the same direction, implying a positive cross-sectional correlation of 0.62 between these two household attributes. Younger, better educated, and higher-income households have less inertia and less inattention. Financial wealth and housing wealth have opposite effects, with the least inertia and inattention among households whose housing wealth is high relative to their financial wealth. There is suggestive evidence of persistent unobserved heterogeneity in attention.

Discounting Behaviour and the Magnitude Effect: Evidence from a Field Experiment in Denmark

We evaluate the claim that individuals exhibit a magnitude effect in their discounting behaviour, where higher discount rates are inferred from choices made with lower principals, all else being equal. If the magnitude effect is quantitatively significant, it is not appropriate to use one discount rate that is independent of the scale of the project for cost–benefit analysis and capital budgeting. Using data from a field experiment in Denmark, we find statistically significant evidence of a magnitude effect that is much smaller than is claimed. This evidence surfaces only if one controls for unobserved individual heterogeneity in the population.

Asset Integration and Attitudes to Risk: Theory and Evidence

We provide evidence that choices over small-stakes bets are consistent with assumptions of some payoff calibration paradoxes. We then exploit the existence of detailed information on individual wealth of our experimental subjects in Denmark and directly estimate risk attitudes and the degree of asset integration. We discover that behavior is consistent with partial, rather than full, asset integration. The implied risk attitudes from estimating these specifications indicate risk premiums and certainty equivalents that are a priori plausible. This theory and evidence suggest one constructive solution to payoff calibration paradoxes.

Multiattribute Utility Theory, Intertemporal Utility and Correlation Aversion

Convenient assumptions about qualitative properties of the intertemporal utility function have generated counterintuitive implications for the relationship between atemporal risk aversion and the intertemporal elasticity of substitution. If the intertemporal utility function is additively separable, then the latter two concepts are the inverse of each other. We review a theoretical specification with a long lineage in the literature on multi†attribute utility and use this theoretical structure to guide the design of a series of experiments that allow us to identify and estimate intertemporal correlation aversion. Our results show that subjects are correlation averse over lotteries with intertemporal income profiles.

Carrots that Look Like Sticks: Toward an Understanding of Multitasking Incentive Schemes

Constructing compensation schemes for effort in multidimensional tasks is complex, particularly when some dimensions are not easily observable. When incentive schemes contractually reward workers for easily observed measures, such as quantity produced, the standard model predicts that unrewarded dimensions, such as quality, will be neglected. Yet, there remains mixed empirical evidence in favor of this standard principal-agent model prediction. This article reconciles the literature using both theory and empirical evidence. The theory outlines conditions under which principals can use a piece rate scheme to induce higher quantity and quality levels than analogous fixed wage schemes. Making use of a series of complementary laboratory and field experiments we show that this effect occurs because the agent is uncertain about the principals monitoring ability and the principals choice of a piece rate signals to the agent that she is efficient at monitoring.

Fire Sales and House Prices: Evidence from Estate Sales Due to Sudden Death

This study investigates when forced sales of real estate turn into fire sales by using a natural experiment that allows us to separate supply and demand effects: Forced sales result from sudden death of house owners and are thus unrelated to current market conditions. We find that forced sales result in fire sale discounts. Discounts increase when the sale is urgent, market conditions are poor, and the seller is financially constrained. Overall, our study identifies when forced sales lead to fire sale discounts, and highlights that fire sales occur even in the absence of temporary demand shocks.
