What Do We Learn From Schumpeterian Growth Theory?
Howitt, Peter; Aghion, Philippe; Akcigit, Ufuk - National Bureau of Economic Research (NBER) - 2013
Schumpeterian growth theory has "operationalized" Schumpeter''s notion of creative destruction by developing models based on this concept. These models shed light on several aspects of the growth process which could not be properly addressed by alternative theories. In this survey, we focus on...

Digital Dark Matter and the Economic Contribution of Apache
Greenstein, Shane Mitchell; Nagle, Frank - National Bureau of Economic Research (NBER) - 2013
Researchers have long hypothesized that spillovers from government, university, and private company R&D contribute to economic growth, but these contributions may be difficult to measure when they take a non-pecuniary form. The growth of networking devices and the Internet in the 1990s and 2000s...

Lens or Prism? Patent Citations as a Measure of Knowledge Flows from Public Research
Roach, Michael; Cohen, Wesley M. - National Bureau of Economic Research (NBER) - 2012
This paper assesses the validity and accuracy of firms' backward patent citations as a measure of knowledge flows from public research by employing a newly constructed dataset that matches patents to survey data at the level of the R&D lab. Using survey-based measures of the dimensions of...

Back to Basics: Basic Research Spillovers, Innovation Policy and Growth
Akcigit, Ufuk; Hanley, Douglas; Serrano-Velarde, Nicolas - National Bureau of Economic Research (NBER) - 2013
This paper introduces a model of endogenous growth through basic and applied research. Basic research differs from applied research in the nature and the magnitude of the generated spillovers. We propose a novel way of empirically identifying these spillovers and embed them in a general...

Evidence of a Modest Price Decline in US Broadband Services
Greenstein, Shane Mitchell; McDevitt, Ryan C. - National Bureau of Economic Research (NBER) - 2010
In this paper, we construct a price index for broadband services in the United States between 2004 and 2009. We analyze over 1500 service contracts offered by DSL and cable providers in the United States. We employ a mix of matched-model methods and hedonic price index estimations to adjust for...

The US Productivity Slowdown, the Baby Boom, and Management Quality
Feyrer, James - National Bureau of Economic Research (NBER) - 2009
This paper examines whether management changes caused by the entry of the baby boom into the workforce explain the US productivity slowdown in the 1970s and resurgence in the 1990s. Lucas (1978) suggests that the quality of managers plays a significant role in determining output. If there is...

Measuring the Welfare Gain from Personal Computers: A Macroeconomic Approach
Greenwood, Jeremy; Kopecky, Karen A. - National Bureau of Economic Research (NBER) - 2007
The welfare gain to consumers from the introduction of personal computers is estimated here. A simple model of consumer demand is formulated that uses a slightly modified version of standard preferences. The modification permits marginal utility, and hence total utility, to be finite when the...

The Broadband Bonus: Accounting for Broadband Internet's Impact on U.S. GDP
Greenstein, Shane Mitchell; McDevitt, Ryan C. - National Bureau of Economic Research (NBER) - 2009
How much economic value did the diffusion of broadband create? We provide benchmark estimates for 1999 to 2006. We observe $39 billion of total revenue in Internet access in 2006, with broadband accounting for $28 billion of this total. Depending on the estimate, households generated $20 to $22...

Five Facts You Need to Know About Technology Diffusion
Comin, Diego; Hobijn, Bart; Rovito, Emilie - National Bureau of Economic Research (NBER) - 2006
This paper presents a new data set on the diffusion of about 115 technologies in over 150 countries over the last 200 years. We use this comprehensive data set to uncover general patterns of technology diffusion. Our main 5 findings are as follows: (i) Once the intensive margin is measured,...
