Must-Read: : Lobbyists Are Behind the Rise in Corporate Profits: “I tease apart the factors associated with the growth in corporate valuations relative to assets (Tobin’s Q) and the growth in operating margins…
…the roles of R&D, spending on advertising and marketing, and on administrative costs, including IT. I also consider investments in lobbying, political campaign spending, and regulation; and I look for links between rising profits and industry concentration and stock volatility. I find that investments in conventional capital assets like machinery and spending on R&D together account for a substantial part of the rise in valuations and profits, especially during the 1990s. However, since 2000, political activity and regulation account for a surprisingly large share of the increase…. Lobbying and political campaign spending can result in favorable regulatory changes, and several studies find the returns to these investments can be quite large. For example, one study finds that for each dollar spent lobbying for a tax break, firms received returns in excess of $220.
It is less obvious, however, that regulation in general should be associated with higher profits. Indeed, critics of the regulatory state regularly decry the costs imposed by regulations. Yet even regulations that impose costs might raise profits indirectly, since costs to incumbents are also entry barriers for prospective entrants…. The pattern around the 1992 Cable Act is representative: I find that firms experiencing major regulatory change see their valuations rise 12% compared to closely matched control groups. Smaller regulatory changes are also associated with a subsequent rise in firm market values and profits. This research supports the view that political rent seeking is responsible for a significant portion of the rise in profits….
Two characteristics make these changes particularly worrisome. First, the link between regulation and profits is highly concentrated in a small number of politically influential industries. Among non-financial corporations, most of the effect is accounted for by just five industries: pharmaceuticals/chemicals, petroleum refining, transportation equipment/defense, utilities, and communications. These industries comprise, in effect, a ‘rent seeking sector.’… Those firms may skew policy for the entire economy. For example, the pharmaceutical industry has actively stymied efforts to address problems of patent trolls that affect many other industries. Second, while political rent seeking is nothing new, the outsize effect of political rent seeking on profits and firm values is a recent development, largely occurring since 2000…
