The Corporate Value of (Corrupt) Lobbying

Abstract

Using an event study, we examine whether the stock market considers corporate lobbying to be a value-enhancing activity. On January 3, 2006, lobbyist Jack Abramoff pleaded guilty to bribing politicians, which generated intense scrutiny of lobbyists, limiting their political influence. Using this event as a negative exogenous shock to the ability of firms to lobby, we show that a firm that spends $100,000 more on lobbying in the three years prior to 2006, experiences a loss of about $1.2 million in value around the guilty plea. We also find results consistent with the view that part of the value from lobbying may arise from potentially unethical practices.
