Why are American firms doing so well?

Sebastian Mallaby has a fascinating column in the Washington Post about why U.S. firms have been outperforming other global firms over the past decade: Despite all the nostalgia for the era when GM dominated the world's car industry, the heyday of American business may actually be now. The dawn of this heyday came in 1995. In the two preceding decades, the productivity of American workers had grown more slowly than that of Japanese and European competitors. But in the decade since 1995, U.S. labor productivity growth has outstripped foreign rivals'. Meanwhile U.S. firms' return on equity -- that is, the efficiency with which they manage the capital entrusted to them -- has pulled away from that of Japan, France and Germany, according to data provided by Standard & Poor's Compustat. Other measures tell a similar story.... The (British) Financial Times publishes an annual list of the world's most respected companies. In 2004 and again in 2005, no fewer than 12 of the top 15 slots were occupied by American firms. Or consider the database on management quality constructed by Nick Bloom and John Van Reenen of Stanford University and the London School of Economics. This duo organized a survey of 732 medium-sized American and European companies and measured their management procedures against benchmarks of best practice. The result: American firms, including the subsidiaries of American firms in Europe, are simply better managed than European rivals. In fact, superior American management accounts for more than half of the productivity gap between American and European firms.... Competition and meritocracy cannot explain all of America's superiority, however. The U.S. economy has always had these advantages but hasn't always trounced overseas rivals. Nor is it enough to say that Americans work harder than Europeans, since the productivity numbers show that Americans are boosting what they achieve per hour. And anyone who explains America's superiority by saying that the country is more "dynamic" or "creative" is merely relabeling the mystery we're trying to solve. The best guess about the "X factor" is that America's business culture is peculiarly well-suited to contemporary challenges. American business is not especially good at coaxing productivity out of factory workers: The era when this was all-important was the heyday of Germany and Japan. But American business excels at managing service workers and knowledge workers: at equipping these people with technology, empowering them with the right level of independence and paying for performance. So the era of decentralized "network" businesses is the American era. Moreover, America's business culture is perfectly matched to globalization. American executive suites and MBA courses are full of talented immigrants, so American managers think nothing of working in multicultural firms. The immigrants have links to their home countries, so Americans have an advantage in establishing global supply chains. The elites of Asia and Latin America compete to attend U.S. universities; when they return to their countries, they are keener to join the local operation of a U.S. company than of a German or Japanese one.
