These slides summarize a paper on opportunism by corporate insiders. We show that opportunistic insiders can be identified through the profitability of their trades prior to quarterly earnings announcements (QEAs), and that opportunistic trading is associated with various kinds of...

We present evidence of first impression bias among finance professionals in the field. Equity analysts' forecasts, target prices, and recommendations suffer from first impression bias. If a firm performs particularly well (poorly) in the year before an analyst follows it, that analyst tends to...

This paper tests the hypothesis that irrational market misvaluation affects firms' takeover behavior. We employ two contemporaneous proxies for market misvaluation, pre-takeover book/price ratios and pre-takeover ratios of residual income model value to price. Misvaluation of bidders and targets...

Instructional presentation slides.What drives innovation, risk taking, and investment booms? We study these phenomena using a model of decision making by firms that make biased observations of prior returns. We assume that firms are more likely to observe large successes than small successes or...
