Why do the largest industrial firms share a common founding era?
Core argument: Among 2018 Fortune 1,000 industrials, firms founded between 1880 and 1920 are the most represented cohort, and top manufacturing firms in the 1910s, 1950s, and 2010s alike predominantly date back to around 1900.
In manufacturing, top firms in the 1910s, 1950s, and 2010s predominantly date back to around 1900, [though] even as this special generation persists, turnover among [these] top firms has been substantial. In Figure 1, we plot the number of 2018 Fortune 1,000 companies that originated in each decade, based on the firm’s industry in 2018. For industrials, we observe that the cohort from 1880 to 1920 is most represented among today’s largest industrials. In contrast the largest retailers and wholesalers have always stayed 60 to 70 years old on average, without a special generation. Today, birth years of services companies cluster around 1960 to 1980; few large ones existed before, and few services companies would qualify for the largest businesses in the economy until recently. In a model of firm dynamics a special generation can arise from an industrial revolution, through the adoption of a scalable technology and learning-by-doing; lasting nonstationarity among the dynamics of top firms can result from the long echoes of technological change. [For] retailers and wholesalers, learning appears absent, so a special generation would be harder to sustain.
