We develop measures of labor-saving and labor-augmenting technology exposure using textual analysis of patents and job tasks. Using US administrative data, we show that both measures negatively predict earnings growth of individual incumbent workers. While labor-saving technologies predict...

Industrialized countries have long seen relatively stable growth in output per capita and a stable labor share. AI may be transformative, in the sense that it may break one or both of these stylized facts. This review outlines the ways this may happen by placing several strands of the literature...

A consensus in the growth literature is that scale effects of R&D are non-existent across mature industrialized economies. However, the scrutiny across emerging economies is lacklustre at best. The empirical studies of scale effects also leave the issues of unbalanced regression (non-standard...

We investigate the speed at which clusters of invention for a technology migrate spatially following breakthrough inventions. We identify breakthrough inventions as the top one percent of US inventions for a technology during 1975-1984 in terms of subsequent citations. Patenting growth is...

The sustained increase in productivity gains from the spread of ICTs may increase potential output growth in the medium to long term via capital deepening effects and total factor productivity (TFP) gains, and in the short to medium term via the lagged adjustment of wages to productivity gains....

How much technological change progress has there been in structures? An attempt is made to measure this using panel data on the age and rents of buildings. The data are interpreted with the help of a vintage capital model where buildings are replaced with some chosen periodicity. The key is a...

This is a specific investigation of the importance of technological change specific to new investment goods for postwar U.S. aggregate fluctuations. A growth model that incorporates this form of technological change is calibrated to U.S. data and simulated, using the relative price of new...

Advanced economies have experienced a tremendous increase in material well-being since the industrial revolution. Modern innovations such as personal computers, laser surgery, jet airplanes, and satellite communication have made us rich and transformed the way we live and work. But technological...

Do legal institutions governing financial contracts affect the nature of real investments in the economy? We develop a simple model and provide evidence that the answer to this question is yes. We consider a levered firm's choice of investment between innovative and conservative technologies, on...

Two basic methods for estimating total factor productivity (TFP) and technical change (TC) have been implemented : the standard econometric approach and a deterministic, non-parametric approach, which measures input and output distance functions.
