WASHINGTON – The fight over corporate political donations is evolving from whether such gifts are in the public's interest to whether they're even in the interest of the companies themselves.
A pair of University of Minnesota finance professors who looked at the question found that on average, for every $10,000 a company donates to politics, its stock market value declines by $1.33 million in the next year.
The conclusion, from Rajesh Aggarwal and Tracy Wang of the U's Carlson School of Management, along with Felix Meschke of the University of Kansas School of Business, adds to a growing body of research that suggests that businesses' contributions generally hurt their shareholders rather than help them.
The researchers say companies that use their money for political donations tend to spend less on research and development and investment.
"This was strictly an academic exercise," Aggarwal said. "But I am persuaded that in many cases it is not in the shareholders' interests to be making political donations."
The issue is important in Minnesota, where activists have introduced shareholder ballot measures at both Target and 3M calling for studies on the feasibility of banning many types of donations. Both companies declined to comment on the academic research.
But the professors' conclusions are heresy to the political culture of Washington, where highly paid lobbyists and political fundraisers are presumed to rule.
The Manhattan Institute went so far as to issue a 40-page report titled "Corporate Political Spending: Why the New Critics Are Wrong." The report criticized Aggarwal and Harvard law professor John Coates by name.
