Are Risk Aversion and Impatience Related to Cognitive Ability?
Dohmen Thomas,Falk Armin,Huffman David
This paper investigates whether risk aversion and impatience are correlated with cognitive ability. We conduct incentive compatible choice experiments measuring risk aversion, and impatience over an annual time horizon, for a representative sample of roughly 1,000 German adults. A measure of cognitive ability is provided by two submodules of one of the most widely used IQ tests. Interviews are conducted in subjects'' own homes. We find that lower cognitive ability is associated with greater risk aversion, and more pronounced impatience. These relationships are statistically and economically significant, and robust to controlling for personal characteristics, educational attainment, income, and measures of liquidity constraints.

Are civil servants different?
There is a huge debate about the public/private sector wage premium and the extent to which the public sector should "take the hit" in adjusting public expenditure. This paper asks whether public servants are different in two important domains:
Buurman, Margaretha , Dur, Robert , van den Bossche, Seth
We assess whether public sector employees have a stronger inclination to serve others and are more risk averse than employees in the private sector. A unique feature of our study is that we use revealed rather than stated preferences data. Respondents of a large-scale survey were offered a substantial reward and could choose between a widely redeemable gift certificate, a lottery ticket, or making a donation to a charity. Our analysis shows that public sector employees are significantly less likely to choose the risky option (lottery) and, at the start of their career, significantly more likely to choose the pro-social option (charity). However, when tenure increases, this difference in pro-social inclinations disappears and, later on, even reverses. Our results further suggest that quite a few public sector employees do not contribute to charity because they feel that they already contribute enough to society at work for too little.

The Development of Personality Over the Life Cycle
Bart Golsteyn will be giving a seminar at 1pm in Geary tomorrow on "Economics and Personality." Borgahns and Golsteyn (2008) have done some work with the DBN Dutch panel data to examine whether changes in personality are related to changes in outcomes and/or specific events and activities during the life cycle.
They report that individuals become more extraverted, conscientious and emotionally stable across the life course. Openness to experience has a hump-shaped relation with age. Risk aversion increases dramatically after adolescence but remains relatively stable thereafter. They also report that individuals who start their college education become more extraverted and agreeable but less emotionally stable and conscientious.
In addition, Borgahns and Golsteyn report that time preference has a U-shaped relation with age: adolescents have very high time preference, then at 36 years of age time preference reaches its minimum, after which it increases again. This is the first longitudinal evidence that we know exists on time preferences. As we mentioned on the blog before, no longitudinal study has previously measured the mean-level stability of time preference over the life cycle, according to Frederick et al. (2002).

Is the way that people make risky choices, or tradeoffs over time, related to cognitive ability? This paper investigates whether there is a link between cognitive ability, risk aversion, and impatience, using a representative sample of the population and incentive compatible measures. We conduct choice experiments measuring risk aversion, and impatience over an annual time horizon, for a randomly drawn sample of roughly 1,000 German adults. Subjects also take part in two different tests of cognitive ability, which correspond to sub-modules of one of the most widely used IQ tests. Interviews are conducted in subjects' own homes. We find that lower cognitive ability is associated with significantly more impatient behavior in the experiments, and with greater risk aversion. This relationship is robust to controlling for personal characteristics, educational attainment, income, and measures of credit constraints.
