The information revolution currently underway has changed the economy in ways that are hard to measure using conventional GDP procedures. The information available to consumers has increased dramatically as a result of the Internet and its applications, and new mobile communication devices have...

GDP is a closely watched indicator of the current health of the economy and an important tool of economic policy. It has been called one of the great inventions of the 20th Century. It is not, however, a persuasive indicator of individual wellbeing or economic progress. There have been calls to...

A great deal of research has been devoted to the effects of technical change on economic growth. Less attention has been given to the factors driving the growth of the technological innovators themselves. This paper examines the case of one of the central contributors to the IT revolution, the...

Incomes per capita have grown dramatically over the past two centuries, but the increase has been unevenly spread across time and across the world. Growth accounting is the principal quantitative tool for understanding this phenomenon, and for assessing the prospects for further increases in...

Economists have long recognized that total factor productivity is an important factor in the process of economic growth. However, just how important it is has been a matter of ongoing controversy. Part of this controversy is about methods and assumptions. Total factor productivity growth is...

This paper shows that those low and middle income countries that use infrastructure inefficiently pay a growth penalty in the form of a much smaller benefit from infrastructure investments. The magnitude of this penalty is apparent when the growth experience of Africa is compared with that of...

This paper argues that productivity puzzles like the Solow Paradox arise, in part, from the omission of an important dimension of the debate: the resource cost of achieving a given rate of technical change. A remedy is proposed in which a new parameter, defined as the cost elasticity of...

Many technological innovations are introduced through improvements in the design of new investment goods, thus raising the possibility that capital-embodied technical change may be a significant source of total factor productivity growth. There are, however, no systematic estimates of the size...

A number of recent papers have examined the role of environmental variables in accounting for economic growth, and have concluded that net measures of national product are superior to gross measures in portraying the outcome of the growth process. This paper argues that the two measures are not...
