From today’s WSJ, by Chang-Tai Hsieh and Esteban Rossi-Hansberg:
If you live in a midsize American city, you’ve probably noticed that an increasing share of local services are provided by chain establishments such as the Cheesecake Factory and Wegmans. Why? It’s because the industrial revolution that transformed U.S. manufacturing more than a century ago is finally reaching many local services, which had long resisted standardization.
…Locals sometimes lament when a new chain in town bears down on a mom-and-pop shop. But in the past four decades industries in which top firms have grown in share have created many more jobs than ones where market share is dispersed among small peers. Companies that have taken advantage of the industrial revolution in services grow by expanding into smaller cities or exurbs, and provide competition to previously dominant local monopolists. This brings jobs, as well as cheaper and higher quality services from groceries to health care, to areas that need them most.
In contrast, employment has shrunk in sectors still dominated by small independent operators, such as plumbing and electrical wiring. Over the past four decades, the growth of the top 10% of firms in local services in a given year has accounted for 80% of the cumulative wage and employment growth in the U.S.
Might this also someday mean that services will become easier to export? I am also happy to recommend the authors’ underlying piece The Industrial Revolution in Services.
