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,...

Adoption of health information and communication technologies ("HICT") has surged over the past two decades. We survey the medical and economic literature on HICT adoption and its impact on clinical outcomes, productivity and labor. We find that HICT improves clinical outcomes and lowers...

In recent years, the designs of many new blockchain applications have been inspired by the Byzantine fault tolerance (BFT) problem. While traditional BFT protocols assume that most system nodes are honest (in that they follow the protocol), we recognize that blockchains are deployed in...

This paper examines whether there are complementarities between investments in ICT, R&D and organizational innovation, and the effects of different investment profiles on total factor productivity growth on Dutch firm-level data. We estimate an integrated model of investment profile adoption and...

Modern information technologies have greatly facilitated timely dissemination of information to a broad base of investors at low costs. To examine their effects on the real economy, we exploit the staggered implementation of the EDGAR system from 1993 to 1996 as a shock to information...
