Now it's personal / Prasanna Tambe in Management science, Vol. 58 N° 4 (Avril 2012) 

Public ISBD [article]  in Management science > Vol. 58 N° 4 (Avril 2012) . - pp. 678-695 Titre : Now it's personal : Offshoring and the shifting skill composition of the U.S. information technology workforce Type de document : texte imprimé Auteurs : Prasanna Tambe, Auteur ; Lorin M. Hitt, Auteur Année de publication : 2012 Article en page(s) : pp. 678-695 Note générale : Management Langues : Anglais (eng) Mots-clés : Information  systems  IT  policy  and  management  Management  of  IT  human  resources  Organizational  change  Outsourcing  Offshoring Résumé : We combine new information technology (IT) offshoring and IT workforce microdata to investigate how the use of IT offshore captive centers is affecting the skill composition of the U.S. onshore IT workforce. The analysis is based on the theory that occupations involving tasks that are “tradable,” such as tasks that require little personal communication or hands-on interaction with U.S.-based objects, are vulnerable to being moved offshore. Consistent with this theory, we find that firms that have offshore IT captive centers have 8% less of their onshore IT workforce involved in tradable occupations; those without offshore captive centers have increased the proportion of onshore employment in these same occupations by 3%. In addition, we find that hourly IT workers (e.g., IT contractors) are disproportionately employed in tradable jobs, and their onshore employment is 2%–3% lower in firms with offshore captive centers. These findings persist after considering different measures of employment composition, including controls for human capital, firm performance, domestic outsourcing, and whether firms choose to build or buy software. Instrumental variables and corroborating regressions suggest that our estimates are conservative—the magnitude of the effect generally rises after accounting for reverse causality and measurement error.

The extroverted firm / Prasanna Tambe in Management science, Vol. 58 N° 5 (Mai 2012) 

Public ISBD [article]  in Management science > Vol. 58 N° 5 (Mai 2012) . - pp. 843-859 Titre : The extroverted firm : How external information practices affect innovation and productivity Type de document : texte imprimé Auteurs : Prasanna Tambe, Auteur ; Lorin M. Hitt, Auteur ; Erik Brynjolfsson, Auteur Année de publication : 2012 Article en page(s) : pp. 843-859 Note générale : Management Langues : Anglais (eng) Mots-clés : Information  technology  Productivity  Organizational  practices  External  focus  Complementarities  High-performance  work  practices  Product  development  High-tech  clusters Résumé : We gather detailed data on organizational practices and information technology (IT) use at 253 firms to examine the hypothesis that external focus—the ability of a firm to detect and therefore respond to changes in its external operating environment—increases returns to IT, especially when combined with decentralized decision making. First, using survey-based measures, we find that external focus is correlated with both organizational decentralization, and IT investment. Second, we find that a cluster of practices including external focus, decentralization, and IT is associated with improved product innovation capabilities. Third, we develop and test a three-way complementarities model that indicates that the combination of external focus, decentralization, and IT is associated with significantly higher productivity in our sample. We also introduce a new set of instrumental variables representing barriers to IT-related organizational change and find that our results are robust when we account for the potential endogeneity of organizational investments. Our results may help explain why firms that operate in information-rich environments such as high-technology clusters or areas with high worker mobility have experienced especially high returns to IT investment and suggest a set of practices that some managers may be able to use to increase their returns from IT investments.
