"Innovation and entrepreneurship are ubiquitous today, both as fields of study and as starting points for conversations among experts in government and economic development. But while these areas on continue to attract public and private investments, many measurements of their resulting economic...

In this paper an attempt is made to answer two questions:1) What set of factors explains the recent slowdown of the U.S. aggregate labor productivity, and 2) whether the same set of forces account for the slowdown of sectoral productivity growth as well. We specify a model which relates measured...

This paper is concerned with the growth of individual earnings over time. Four aspects of time are distinguished: experience, age, vintage and calendar year. The first section of the paper provides a brief outline of a theory of planned growth in earnings. The second and main section of the...

Why did per capita income divergence occur so dramatically during the 19th Century, rather than at the outset of the Industrial Revolution? How were some countries able to reverse this trend during the globalization of the late 20th Century? To answer these questions, this paper develops a...

A defiining feature of modern economic growth is the systematic application of science to advance technology. However, despite sustained progress in scientific knowledge, recent productivity growth in the U.S. has been disappointing. We review major changes in the American innovation ecosystem...

We build up from the plant level an "aggregate(d)" Solow residual by estimating every U.S. manufacturing plant's contribution to the change in aggregate final demand between 1976 and 1996. Our framework uses the Petrin and Levinsohn (2010) definition of aggregate productivity growth, which...

In the aftermath of World War II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies....

We derive aggregate growth-accounting implications for a two-sector economy with heterogeneous capital subsidies and monopoly power. In this economy, measures of total factor productivity (TFP) growth in terms of quantities (the primal) and real factor prices (the dual) can diverge from each...

Research done to date has demonstrated that artistic innovators can usefully be divided into two types. Experimental innovators seek to record their perceptions. They proceed tentatively, by trial and error, building their skills gradually, and making their greatest contributions late in their...
