Underpricing and entrepreneurial wealth losses in IPOs: theory and evidence

We model owners as solving a multidimensional problem when takingtheir firms public. Owners can affect the level of underpricingthrough the choices they make in promoting an issue, such aswhich underwriter to hire or on what exchange to list. The benefitsof reducing underpricing in this way depend on the owners' participationin the offering and the magnitude of the dilution they sufferon retained shares. We argue that the extent to which ownerstrade off underpricing and promotion is determined by the minimizationof their wealth losses. Evidence from a sample of U.S. initialpublic offering confirms our empirical predictions.     

The effect of class session length on student performance,homework, and instructor evaluations in an introductory accounting course

The author examines the effect of class format on student performance, time spent on homework, and instructor evaluations. The findings are unique and add to a limited body of literature. Each group comprised similar undergraduate students who received the same number of instructional hours, same assignments and were taught by the same instructor. Students in the one-day-a-week class performed significantly better than students in the two-days-a-week class. Students in the one-day-a-week class spent more time on online homework, although the difference was not statistically significant. Differences in instructor evaluation ratings were nominal.
