Corporations are increasingly active in U.S. politics, and their investors deserve to know where the money is going. Click here to read Susan Holmberg’s new paper, “A Cost-Benefit Analysis of Corporate Political Spending Disclosure.”

A core assumption of the Supreme Court’s opinion in 2010’s troubling Citizens United case, which broadened corporations’ abilities to use their money for political purposes, was that shareholders could decide for themselves whether they agreed with the ways that money was being spent.

According to Justice Anthony Kennedy, who delivered the opinion for the Court, “With the advent of the Internet, prompt disclosure of expenditures can provide shareholders and citizens with the information needed to hold corporations and elected officials accountable for their positions and supporters. Shareholders can determine whether their corporation’s political speech advances the corporation’s interest in making profits, and citizens can see whether elected officials are ‘in the pocket’ of so-called moneyed interests.”

The problem with this particular assumption, which economists call perfect information, is that corporations are — surprise surprise — not legally obligated to share information on political spending with their shareholders or the public. In August 2011, a group of high-profile law professors filed a petition with the Securities and Exchange Commission, calling on the agency to require public companies to disclose what corporate resources they spend on political activities because “most political spending remains opaque to investors in most publicly traded companies.”

Why do companies spend money on politics? The answer seems obvious: they want to generate profits. They are seeking advantages like reduced trade barriers, government contracts, easier regulatory inspections, and lower tax rates. For more on this point, see my colleague Tom Ferguson’s recent paper with Paul Jorgensen and Jie Chen, which reveals how “Too Big to Fail” Wall Street firms and telecom companies have captured the GOP and the Democrats, respectively. (As an aside, isn’t it odd that the same companies orchestrating the expansion of the surveillance state are so concerned about their own privacy?)

But there is sufficient research to suggest there is another, more covert reason that has serious consequences for shareholders. In my recently published Roosevelt Institute paper on the costs and benefits of this disclosure rule, I cite several studies that show corporate executives frequently spend on politics for their own personal advantage rather than the company’s bottom line. These personal benefits include things like prestige, a future political career, star power, or assistance for political allies.

With these kinds of distorted incentives, the lack of information available to the public about corporate political spending puts shareholders and potential investors at enormous risk. Why would they want to invest in a company that is undertaking activities that are more likely to benefit its executives than its investors? Requiring corporations to disclose their political spending, on the other hand, would do the following:

—Enable investors to make informed investment decisions. Good information is always key to helping potential shareholders calculate the risk they are taking by investing in a company or helping current shareholders decide if they want to hold on to a company’s stock.

—Create the motivation for corporate executives to focus less on their own personal benefit and more on the political spending that would increase shareholder wealth. By disclosing their political activities, corporate executives would have less of an opportunity to waste company resources for their own advantage.

—Benefit corporations that already share their political spending information. Research suggests companies that already disclose SEC-required information enjoy a bump in stock returns when the particular rule is put in place.

Two years after the lawyers submitted their petition, File No. 4-637 is finally on the SEC’s official agenda and support for the disclosure rule is overwhelming. Recent polling finds that 79 percent of surveyed Republicans and nearly 100 percent of Democrats support the rule, and more than 600,000 public comments supporting the rule have been submitted to the SEC. Major institutional investors are also in agreement. Former Vanguard mutual fund CEO John C. Bogle, six state treasurers, CalPERS and other pension funds, and many more are also in support. The rule also has the endorsement of small-business owners across the country, as large companies have a competitive advantage over smaller businesses because of their ability to influence lawmakers and agencies through campaign contributions and lobbying.

The pushback against disclosure is typically about the costs of disclosure. But companies already have to document their political spending for the IRS, so the additional cost would be, at most, the few hours it would require an employee to copy and paste data from an internal file into a public one. Furthermore, companies already submit annual forms to the SEC. The political spending information would simply be a few additional lines of text added to these forms.

A more valid concern about this rule is that, if companies are required to disclose this information to the SEC, the information could be exploited by their competitors and harm the companies’ bottom line. But corporate political activities are already well known among industry competitors. In fact, sometimes political spending is even coordinated among industry groups. The people who are actually excluded from this information are the ones who need it most: investors.

At a briefing held this past Wednesday organized by the Corporate Reform Coalition, Senators Elizabeth Warren (D-MA) and Robert Menendez (D-NJ) called for the SEC to finally adopt this important rule. “There is no excuse,” said Warren, “There is no reason […] for saying a corporation wants to be able to spend shareholders’ money and not tell shareholders how that money is being spent.”
