This paper presents a new data set on the diffusion of about 115 technologies in over 150 countries over the last 200 years. We use this comprehensive data set to uncover general patterns of technology diffusion. Our main 5 findings are as follows: (i) Once the intensive margin is measured,...

Since the start of the pandemic the U.S. labor market has been characterized as being plagued by missing jobs, i.e. payroll employment has fallen more than five million jobs short of its pre-pandemic trend, and missing workers, i.e. the participation rate has declined by 1.2 percentage points: A...

A new index of the U.S. high-tech sector - drawing upon a range of technology-specific data - has the potential to offer a more timely assessment of economic activity than has been possible to date. The index suggests that while the tech sector has rebounded from its poor performance in the...

Since 1968, the ratio of stock market capitalization to GDP has varied by a factor of 5. In 1972, the ratio stood at above unity, but by 1974, it had fallen to 0.45 where it stayed for the next decade. It then began a steady climb, and today it stands above 2. We argue that the IT revolution was...

We show that a negative relative demand shock in a sector with downwardly rigid prices, like the service sector, can generate substantial inflation. Such a shock induces an equilibrium decline in the relative price of services. If price adjustment costs are non-existent or symmetric, then this...
