As an all-star quintet of economists—David Autor, David Dorn, Lawrence Katz, Christina Patterson, and John Van Reenen—points out, concentration and higher profits can be benign, perhaps even welcome, consequences of technological innovation.

Program in the Department of Economics at Harvard is addressed to students of high promise who wish to prepare themselves in teaching and research in academia or for responsible positions in government, research organizations, or business enterprises. Lawyer-judges Robert Bork and Richard Posner and Nobel laureate economists George Stigler and Oliver Williamson laid the intellectual foundation for this shift, which spread to the policy arena and the courts in the early 1980s. By 2012, Amazon had begun raising prices and had slashed the benefits of Amazon Mom. In the 1950s and 1960s, many mergers — even ones that would have led to relatively modest increases in concentration — were routinely challenged, but in the 1970s the antitrust framework began to shift toward challenging many fewer mergers. This was dubbed “the Walmart effect,” because of the impact of the giant retailer not only on the efficiency of its industry but on the entire U.S. economy. Measured against GDP, corporate after-tax profits are almost double what they were 25 years ago — and higher than at any time since World War II — yet business investment as a share of GDP is up only 13% over the same period.

That’s more worrisome, Haltiwanger says, because it portends slower productivity growth. In a 2002 study, Lawrence White, a New York University economist, concluded that economy-wide concentration had fallen from the beginning of the 1980s to the end of the 1990s. Concentration in hospital markets is also associated with higher prices, with surges of up to 20% following mergers. And BlackRock is hardly the reincarnation of John D. Rockefeller; the firm is managing other people’s money. Today's economic map of the world is characterized by what Porter calls clusters: critical masses in one place of linked industries and institutions—from suppliers to universities to government agencies—that enjoy unusual competitive success in a particular field. The core of the PJM market design, a bid-based-security-constrained-economic-dispatch-with-locational-marginal-prices (BBSCEDLMP) model, works in theory and in practice. Industries in which cross-ownership is greater, they note, tend to have corporate compensation packages that offer less reward for beating the competition than do industries with little cross-ownership. That’s good for shareholders, of course, but it’s not so good for consumers or the overall economy. These include Business Economics, Political Economy and Government, Public Policy, and Health Policy. High and rising profits in an increasingly concentrated market are typically a sign of lessening competition and increased market power by dominant firms. Economic theory suggests that oligopolies — industries in which a few firms dominate without much competition — lead to increases in price and reductions in output. Much of the increase is a result of states extending the occupations for which licenses are required. The short answer: It’s complicated.

Economic theory suggests that oligopolies — industries in which a few firms dominate without much competition — lead to increases in price and reductions in output. And regulators need to pay more attention to protecting economic vitality and consumer well-being — and less to industry lobbyists. And they cite anecdotal evidence undermining the notion that institutional holders are reluctant activists: For example, in the 2017 showdown between Procter & Gamble and activist Nelson Peltz, Vanguard sided with P&G, while State Street and BlackRock voted almost all their shares for Peltz.

In an eyebrow-raising 2017 study, Princeton’s Alan Krueger and Orley Ashenfelter found that 58% of major chains (Burger King, Jiffy Lube, H&R Block, and dozens more) restrict and sometimes prohibit one franchisee from hiring workers away from another, to the obvious detriment of people seeking to change jobs. Consider the wireless telephone business.
