Stock market investment decisions of individuals are positively correlated with that of co-workers. Sorting of unobservably similar individuals to the same workplaces is unlikely to explain our results, as evidenced by the investment behavior of individuals that move between plants. Purchases...

This paper documents evidence consistent with informed trading by individual investors around earnings announcements using a unique dataset of NYSE stocks. We show that intense aggregate individual investor buying (selling) predicts large positive (negative) abnormal returns on and after...

We merge survey data on a sample of individual investors containing test-based measures of financial literacy with administrative records on their assets holding and trades before, during and after the financial crisis of September 2008. This dataset allows us to design three tests of the...

We conduct a laboratory experiment in which we expose participants to situational social norms of approval or disapproval of lying. While participants on average conform to the situational pressure, the results highlight important differences in individual reactions. Situational norms crowd out...

When entering retirement most people face the decision whether they would like their defined contribution account balance paid as a lump sum or to annuitize the amount. The fact that people tend to choose the lump sum even if economic reasons suggest not to is called the annuity puzzle. In a...

A tradition from Knight (1921) argues that more risk tolerant individuals are more likely to become entrepreneurs, but perform worse. We test these predictions with two risk tolerance proxies: stock market participation and personal leverage. Using investment data for 400,000 individuals, we...

An intense debate on the use of limited-voting shares developed in the UK during the 1950s. Using a unique hand-collected dataset, we show that negative news coverage of limited-voting shares is associated with an increase in the relative price of voting and limited-voting shares (the voting...

Theoretical models predict that overconfident investors will trade more than rational investors. We directly test this hypothesis by correlating individual overconfidence scores with several measures of trading volume of individual investors (number of trades, turnover). Approximately 3000...

This paper documents the extent and characteristics of plants and firms in the US that are outside the manufacturing sector according to official government statistics but nonetheless are heavily involved in activities related to the production of manufactured goods. Using new data on...

We economically motivate and then test a range of hypotheses regarding performance and risk differences between UCITS-compliant and other hedge funds. The latter exhibit more suspicious return patterns than do absolute return UCITS (ARUs), but ARUs exhibit higher levels of operational risk. We...
