We offer a model of experimentation and learning with uncertain outcomes, and show that competition leads to less experimentation, extending results for preemption games to experimentation with uncertain outcomes. We compare experimentation under two information settings: when the researchers...

We investigate gender differences and menstrual cycle effects in first-price and second-price sealed-bid auctions with independent private values in a laboratory setting. We find that women bid significantly higher and earn significantly less than men do in the first-price auction, while we find...

This study presents a laboratory experiment of the first and second price sealed bid auctions with independent private values, where the distribution of bidder valuations may be unknown. In our experimental setting, in the first price auction, bids are lower in the presence of ambiguity. This...
