Growth has fallen in the U.S., while firm concentration and profits have risen. Meanwhile, labor's share of national income is down, mostly due to the rising market share of low labor share firms. We propose a theory for these trends in which the driving force is falling firm-level costs of...

Recent work highlights a falling entry rate of new firms and a rising market share of large firms in the United States. To understand how these changing firm demographics have affected growth, we decompose productivity growth into the firms doing the innovating. We trace how much each firm...

At the close of World War II, there were wide-ranging debates about the future of economic developments. Historical experience has since shown that these forecasts were uniformly too pessimistic. Expectations for the American economy focused on the likelihood of secular stagnation; this topic...

Externalities play a central role in most theories of economic growth. We argue that international externalities, in particular, are essential for explaining a number of empirical regularities about growth and development. Foremost among these is that many countries appear to share a common long...

Entrepreneurship, as reflected in the start-up of new firms, the growth and market exit of existing firms, and the ow of venture capital, has been severely curtailed by the lockdown and social distancing measures taken by governments around the world in the fight against COVID-19. This paper,...

Technological innovation has historically contributed to inclusive economic growth in Germany. In more recent decades, however, this contribution has weakened due to the declining impact of technological innovation on labor productivity growth. Fearing that this declining impact would undermine...

Statistical agencies typically impute inflation for disappearing products based on surviving products, which may result in overstated inflation and understated growth. Using U.S. Census data, we apply two ways of assessing the magnitude of "missing growth" for private nonfarm businesses from...

After more than three decades of high growth that was based on an exploration of its low-wage advantage and a relatively favorable demographic pattern in combination with market-oriented reforms and openness to the world economy, China is at a crossroad with a much higher wage and a shrinking...

Theory predicts that global economic growth will stagnate and even come to an end due to slower and eventually negative growth in population. It has been claimed, however, that Artificial Intelligence (AI) may counter this and even cause an economic growth explosion. In this paper, we critically...
