Revisiting the T-Mobile-Sprint Merger (turned out it was pro-competitive despite the fears otherwise)

From Alex Tabarrok.

"T-Mobile’s takeover of Sprint was controversial among analysts. “If this merger is not anticompetitive,” Eleanor Fox, a trade regulation and antitrust law professor at New York University, told reporters in 2020, “it is hard to know what is.” Yale economist and antitrust scholar Fiona Scott Morton delivered her verdict on the deal in a co-authored 2021 article: “The era of aggressive price competition in wireless is over.” The authors predicted that the wireless industry, whittled down to a big three, would “nestle into a cozy triopoly.”

The prediction proved wrong. Average monthly mobile subscription fees dropped sharply. In the three years before the merger, according to government price data, mobile charges declined in real terms by about 8%. In the three years following the merger, the real price decline has been nearly 12%.

These trends were even more impressive given dramatically improving network performance. Before the merger, the top four U.S. carriers delivered data download speeds averaging about 26 megabits per second, nearly all via 3G or 4G. By early 2023, with 5G deployments spreading, Verizon and AT&T data flowed 24% to 39% faster, while T-Mobile was more than three times as fast as before. T-Mobile’s high-speed coverage had also expanded; half of its connections were via 5G by January 2023, against just 10% to 20% for its rivals.

…Further evidence that the merger of T-Mobile and Sprint was pro-competitive was seen with Verizon and AT&T share prices. From 2018 to 2023, Verizon and AT&T stock prices declined sharply, losing more than a third of their real value. The postmerger marketplace was a great victory for T-Mobile but a blow for its rivals. The cozy-cartel thesis collapsed.

That’s the excellent Tom Hazlett writing in the WSJ–useful facts to remember when thinking about the current rise of antitrust."
