Hello My Name is Robert Waldmann

Hi I am Robert Waldmann. rdan has very kindly invited me to guest post here some. I have a blog of my own (to which he kindly linked in the announcement). I am officially an economist, but tend to blog about politics at my home blog. Here I will try to fit the interest in, you know economics.

I wasn’t always like this. Until age 25 I was a biologist. I currently live in Rome Italy. I am irrational and like to write about irrationality. I am also egalitarian.

My latest effort, which is a joint paper with Emanuele Millemaci is about relatively rational people who have dynamically inconsistent preferences. It is strictly empirical. Our hypothesis is that people with more severe dynamic inconsistency would hold less of their wealth as checking account balances, because it is too easy to spend.

This appears to actually be true (Oh I love to blatantly split infinitives)

Dynamically Inconsistent Preferences and Money Demand

Emanuele Millemaci and Robert J. Waldmann

This research wouldn’t have been possible without CentER at the University of
Tilburg which designed the survey and collected the the data.

This paper focuses on two main issues. First, we find that, on average,
households’ discount rates decline. This implies dynamically inconsistent
preferences. Second, we calculate an indicator of the degree of dynamic
inconsistency that may help us to understand how households overcome their
self-control problems. We use a micro dataset containing households’ reports
on the compensation for receiving hypothetical rewards with delays. We find
that individuals with more severely dynamically inconsistent preferences on
average hold a statistically significantly lower share of their total wealth
in checking accounts. A possible interpretation is that subjects use
precommitment strategies to limit their temptation to consume immediately.
