In many cases, patients are unable to shop around or make informed decisions about their care due to a lack of information about the true cost and quality of services.

A very fun chat, and Lawrence and co do a great job splicing it together. Feat. trust, econ games, tax reform failures, pens, me saying like, fairness.
Is #greed fundamental to human nature? Or can we have a society where it doesn’t pose a threat? @UTS_Business's @NathanKettlewe1 provides an economist's view on greed and #trust with @2ser.

Very impressive research by Jan and the team, which they just keep improving (I discussed a version of this paper two years ago and it was an epic then).
Are teachers *generally* better at teaching students of their own sex?. NO in primary education,.YES in secondary education. A 🧵generalizability and same-sex teacher effects.

The first publication from the twins data I'm always talking about. Very happy to have this out 🙂. Grateful to work with @AgnieszkaTymula on this, and also to the editors and referees at JEBO for great feedback. The paper grew a lot through revision.
Wondered about the heritability of different types of trust? Check out our new publication with @NathanKettlewe1 (the driving force behind this research agenda)

The new Netflix documentary follows identical twins as they adopt different diets. This is a great example of a twin study – a uniquely useful research tool in science.

This paper is a product of the Australian Twins Economic Preferences Survey, which people in my network are probably sick of hearing me plug. Nonetheless.

Compared to the meta-estimates, our structural results imply a greater role for genes and family environment and reduced role of unique experiences, in line with expectations. E.g., for risk preferences we estimate heritability of 36-48% compared to 25% in previous literature.

We also find that genetic heritability of time preferences goes away when you jointly estimate with risk preferences. Confoundedness of risk and time preferences not considered in previous work. The family environment explains around 1/3 of variation for time preferences.

See for example the graph below. A is variation explained by genes, C family environment, E unique environment. Using raw choices in a MPL task (blue bars), genes explain very little. But for parameters of an RDU decision function (last two red bars), genes matter a lot.

This helps to deal with measurement and behavioural errors affecting earlier studies. It's also cool to see how different approaches to measuring preferences affect conclusions - turns out, a lot.

We decompose variation in risk and time preferences into genetic and environmental components by extending the classic twin design to cases where outcomes are latent structural parameters governing choice (e.g., coefficients of risk aversion).
