Economists tend to characterize the scope of regulation as a simple matter of expanding or contracting state power. But a political economy perspective emphasizes that social relations abhor a power vacuum. When state authority contracts, private parties fill the gap. That power can feel just as oppressive, and have effects just as pervasive, as garden variety administrative agency enforcement of civil law. As Robert Lee Hale stated, "There is government whenever one person or group can tell others what they must do and when those others have to obey or suffer a penalty."

We are familiar with that power in employer-employee relationships, or when a massive firm extracts concessions from suppliers. But what about when a firm presumes to exercise juridical power, not as a party to a conflict, but the authority deciding it? I worry that such scenarios will become all the more common as massive digital platforms exercise more power over our commercial lives.

A few weeks ago, the Friedrich Ebert Stiftung (a think tank affiliated with the Social Democratic Party in Germany) invited me to speak at their Conference on Digital Capitalism. As European authorities develop long-term plans to address the rise of powerful platforms, they want to know: What is new, or particularly challenging, in digital capitalism?

My answer focused on the identity and aspirations of major digital firms. They are no longer market participants. Rather, in their fields, they are market makers, able to exert regulatory control over the terms on which others can sell goods and services. Moreover, they aspire to displace more government roles over time, replacing the logic of territorial sovereignty with functional sovereignty. In functional arenas from room-letting to transportation to commerce, persons will be increasingly subject to corporate, rather than democratic, control.

For example: Who needs city housing regulators when Airbnb can use data-driven methods to effectively regulate room-letting, then house-letting, and eventually urban planning generally? Why not let Amazon have its own jurisdiction or charter city, or establish special judicial procedures for Foxconn? Some vanguardists of functional sovereignty believe online rating systems could replace state occupational licensure — so rather than having government boards credential workers, a platform like LinkedIn could collect star ratings on them.

In this and later posts, I want to explain how this shift from territorial to functional sovereignty is creating a new digital political economy.
