Eric Crampton ihmettelee:

Grinblatt, Keloharju and Linnainmaa somehow got the individual [pällitesti] test results from all exams from 1982 through 2001 inclusive. And tied it to Finnish tax administration data, an address data set, the Finnish Central Securities Depository Registry (which has records on all Finnish households' portfolios and trades), and census data to measure the effect of IQ on stock market participation, controlling for education and income. --- I'm amazed they were able to get this dataset together. Individual level data combining IQ, income tax records and all stock market activity...fodder for a dozen more papers in there at least. --- No way this paper lands outside the top tier.
