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...

Innovation and Productivity across Four European Countries

Griffith, Rachel; Huergo, Elena; MAIRESSE, Jacques; … - National Bureau of Economic Research (NBER) - 2006

This paper compares the role innovation plays in productivity across the four European countries France, Germany, Spain … and the UK using firm-level data from the internationally harmonized Community Innovation Surveys (CIS3). Despite a … still rare. We apply a structural model that describes the link between R&D expenditure, innovation output and productivity …

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...

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...

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...

World Technology Usage Lags

Comin, Diego; Hobijn, Bart; Rovito, Emilie - National Bureau of Economic Research (NBER) - 2006

We present evidence on the differences in the intensity with which ten major technologies are used in 185 countries across the world. We do so by calculating how many years ago these technologies were used in the U.S. at the same intensity as they are used in the countries in our sample. We...

Quantifying Quality Growth

Bils, Mark Joseph; Klenow, Peter J. - National Bureau of Economic Research (NBER) - 2000

We introduce an instrumental variables approach to estimate the importance of unmeasured quality growth for a set of 66 durable consumer goods. Our instrument is based on predicting which of these 66 goods will display rapid quality growth. Using pooled cross- relatively sections of households...

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,...
