The article focuses on spending caps, and compares those used in politics with many examples in sports economics. In 1999, the party of Israeli Prime Minister Ehud Barak was fined $3.2 million for exceeding Israel's campaign finance caps. Financing caps by the National Collegiate Athletics Association did not prevent The University of Oregon from spending $3 million on their football locker room. Mathematical models are provided in order to prove that spending caps will not necessarily have their intended effect, as they increase the total expended amount by increasing the risk of being fined.

Companies have collected billions in premiums from privately sold put options written on their own stock. It is puzzling that counterparties, investment banks, would agree to make such transactions with better-informed companies which have extraordinary ability to time the market as documented by Jenter et al. (2011). To resolve this puzzle, we develop a model that shows that investment banks, by offering to buy put options from better-informed parties, receive private information about issuing companies. Our model also incorporates the practice of firms (such as Microsoft) of sometimes repurchasing their own put options and thus providing additional private information to investment banks. Empirically, we find support for our theory from an abnormal 9% increase in the stock prices and a 40% increase in the trading volumes around the put sales. Examination of 13D filings reveals that trading by upper management insiders cannot completely account for the change in volume.
