Goldin and Katz's The Race between Education and Technology is a monumental achievement that supplies a unified framework for interpreting how the demand and supply of human capital have shaped the distribution of earnings in the U.S. labor market over the 20th century. This essay reviews the...

As the pace of digitalization and automation accelerates globally, and more disruptive innovations in machine learning, artificial intelligence and robotics are expected, new data sources and measurement tools are needed to complement existing valuable statistics and administrative data. This is...

We analyze investment decisions when information is costly, with and without delegation to an agent. We use a rational-inattention model and compare it with a canonical signal-extraction model. We identify three "investment conditions". In "sour" conditions, no information is acquired and no...

This paper analyzes the mechanisms, other than market size, through which international trade of intermediate goods incorporating state-of-the-art technological knowledge affects accumulation of human capital and wage inequality in the North and South. Under North-South technological diffusion,...

This paper estimates the gender-specific effects of birthweight on a variety of schooling and labor market outcomes. A unique feature of the study is to use micro evidence on the relationship between birthweight - an early measure of nutritional advantage - and schooling outcomes to make...

We argue theoretically and document empirically that aging leads to greater (industrial) automation, and in particular, to more intensive use and development of robots. Using US data, we document that robots substitute for middle-aged workers (those between the ages of (36 and 55). We then show...

In the conventional neoclassical growth model, technical change is generally characterized as “purely labor-augmenting,” a restriction that limits modern civilization to super-humans living in the Stone Age. As a novel and radical departure from conventional growth theory, the model...

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...

There is a long-standing recognition that innovating firms often have higher employment growth. More recently, there is increasing understanding that innovation is concentrated among a small number of generally large firms. We contribute to this debate by showing that the innovation-employment...

Since 1980, economic growth in the U.S. has been fastest in its largest cities. We show that a group of skill- and information-intensive service industries are responsible for all of this new urban bias in recent growth. We then propose a simple explanation centered around the interaction of...
