The invention of new applications based on information and communications technologies (ICTs) has had two economic effects up to now. These applications have transformed production, creating value for applications-inventing companies and their customers and increasing economic growth through...

We combine national administrative data on earnings and participation in subsidized housing to study how the demolition of 160 public housing projects--funded by the HOPE VI program--affected the adult labor market outcomes for 18,500 children. Our empirical strategy compares children exposed to...

A growing number of surveys elicit respondents' expectations for future events on a 0-100 scale of percent chance. These data reveal substantial heaping at multiples of 10 and 5 percent, suggesting that respondents round their reports. This paper studies the nature of rounding by analyzing...

Natural-resource taxation and investment exhibit cycles in a vast number of countries, driving political turmoil and power shifts. Using a rational-expectations model, we show cycles result from governments' inability to commit to future taxes and firms' inability to credibly exit a country...

Online advertising offers unprecedented opportunities for measurement. A host of new metrics, clicks being the leading example, have become widespread in advertising science. New data and experimentation platforms open the door for firms and researchers to measure true causal effects of...

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...

By exploiting establishment-level data, this paper sheds new light on the source of the changes in the structure of production, wages, and employment that have occurred over the last several decades. Based on theoretical work by Caselli (1999) and Kremer and Maskin (1996), we focus on...

Since the mid-1980s many authors have investigated the influence of information technology (IT) on productivity. Until recently there has been no clear evidence that productivity increases as a result of IT spending. This productivity paradox is partly due to the difficulty in correctly...

Recently, the relative demand for skilled labor has increased dramatically. We investigate one of the causes, skill-biased technical change. Advances in information technology (IT) are among the most powerful forces bearing on the economy. Employers who use IT often make complementary...

General purpose technologies (GPTs) push out the production possibility frontier and are of strategic importance to managers and policymakers. While theoretical models that explain the characteristics, benefits, and approaches to create and capture value from GPTs have advanced significantly,...
