March 2017What Drives Differences in Management?
with Nicholas Bloom, Lucia Foster, Ron S. Jarmin, Megha Patnaik, Itay Saporta-Eksten, John Van Reenen: w23300
Partnering with the Census we implement a new survey of “structured” management practices in 32,000 US manufacturing plants. We find an enormous dispersion of management practices across plants, with 40% of this variation across plants within the same firm. This management variation accounts for about a fifth of the spread of productivity, a similar fraction as that accounted for by R&D, and twice as much as explained by IT. We find evidence for four “drivers” of management: competition, business environment, learning spillovers and human capital. Collectively, these drivers account for about a third of the dispersion of structured management practices.
June 2007Information, Technology and Information Worker Productivity: Task Level Evidence
with Sinan Aral, Marshall Van Alstyne: w13172
In an effort to reveal the fine-grained relationships between IT use, patterns of information flows, and individual information-worker productivity, we study task level practices at a midsize executive recruiting firm. We analyze both project-level and individual-level performance using: (1) detailed accounting data on revenues, compensation, project completion rates, and team membership for over 1300 projects spanning 5 years, (2) direct observation of over 125,000 email messages over a period of 10 months by individual workers, and (3) data on a matched set of the same workers' self-reported IT skills, IT use and information sharing. These detailed data permit us to econometrically evaluate a multistage model of production and interaction activities at the firm, and to analyze the relat...

May 1999Information Technology, Workplace Organization and the Demand for Skilled Labor: Firm-Level Evidence
with Timothy F. Bresnahan, Lorin M. Hitt: w7136
Recently, the relative demand for skilled labor has increased dramatically. We investigate one of the causes, skill-biased technical change. Advances in information technology (IT) are among the most powerful forces bearing on the economy. Employers who use IT often make complementary innovations in their organizations and in the services they offer. Our hypothesis is that these co-inventions by IT users change the mix of skills that employers demand. Specifically, we test the hypothesis that it is a cluster of complementary changes involving IT, workplace organization and services that is the key skill-biased technical change. We examine new firm-level data linking several indicators of IT use, workplace organization, and the demand for skilled labor. In both a short-run factor demand f...
