The extension of information and communication technologies to economic activity is changing the labour market in important ways. This article shows that computerization and use of the Internet are associated with greater hours worked as well as higher wages; that IT occupations are rapidly...

Used properly, the term 'new e-conomy' is warranted. Since 1995, there has been a wave of innovation associated with both the production and use of information technology that has been translated into improved US economic performance. In particular, there has been a substantial acceleration in...

The present study is the third in a series of three papers devoted to issues in the measurement of productivity and productivity growth. The major findings are as follows. First, this study shows that the new data set used here, which develops data on total output, business sector output, and...

During the four years 1995-99 U. S. productivity growth experienced a strong revival and achieved growth rates exceeding that of the golden age' of 1913-72. Accordingly many observers have declared the New Economy' (the Internet and the accompanying acceleration of technical change in computers...

Using a unique nationally representative sample of U.S. establishments surveyed in 1993 and 1996, we examine the relationship between workplace innovations and establishment productivity and wages. We match plant level practices with plant level productivity and wage outcomes and estimate...

A surprisingly large amount of commentary today marks the beginning of the dot-com bubble of the late 1990s from either the Netscape Communications initial public offering of 1995 or Alan Greenspan's "irrational exuberance" speech of 1996. We believe that this is wrong: we see little sign that...

We model the relationship between asset float (tradeable shares) and speculative bubbles. Investors trade a stock with limited float because of insider lock-ups. They have heterogeneous beliefs due to overconfidence and face short-sales constraints. A bubble arises as price overweighs optimists'...
