Information, Technology and Information Worker Productivity

We study the fine-grained relationships among information flows, IT use, and individual information-worker productivity, by analyzing work at a midsize executive recruiting firm. We analyze both project-level and individual-level performance using: (1) direct observation of over 125,000 e-mail messages over a period of 10 months by individual workers (2) detailed accounting data on revenues, compensation, project completion rates, and team membership for over 1300 projects spanning 5 years, and (3) survey data on a matched set of the same workers’ 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 relationships among communications flows, key technologies, work practices, and output. We find that (a) the structure and size of workers’ communication networks are highly correlated with their performance; (b) IT use is strongly correlated with productivity but mainly by allowing multitasking rather than by speeding up work; (c) productivity is greatest for small amounts of multitasking but beyond an optimum, multitasking is associated with declining project completion rates and revenue generation; and (d) asynchronous information seeking such as email and database use promotes multitasking while synchronous information seeking over the phone shows a negative correlation. Overall, these data show statistically significant relationships among social networks, technology use, completed projects, and revenues for project-based information workers. Results are consistent with simple production models of queuing and multitasking and these methods can be replicated in other settings, suggesting new frontiers for bridging the research on social networks and IT value.NYU, Stern School of Business, IOMS Department, Center for Digital Economy Researc

Essays on information, technology and information worker productivity

Thesis (Ph. D.)--Massachusetts Institute of Technology, Sloan School of Management, 2007.Includes bibliographical references.I examine how information technology (IT) skills and use, communication network structures, and the distribution and flow of information in organizations impact individual information worker productivity. The work is divided into three essays based on the task level practices of information workers at a midsize executive recruiting firm: Essay 1: "Information, Technology and Information Worker Productivity: Task Level Evidence." I develop and econometrically test a multistage model of production and interaction activities at the firm, and analyze correlations among network structure, characteristics of information flow and real economic output. I find that (a) IT use is positively correlated with non-linear drivers of productivity; (b) the structure and size of workers' communication networks are highly correlated with performance; (c) an inverted-U shaped relationship exists between multitasking and productivity such that, beyond an optimum, more multitasking is associated with declining project completion rates and revenue generation; and (d) asynchronous information seeking such as email and database use promotes multitasking while synchronous information seeking over the phone shows a negative correlation. These data demonstrate a strong correspondence among technology use, social networks, and productivity for project-based information workers.(cont.) Essay 2: "Network Structure and Information Advantage: Structural Determinants of Access to Novel Information and their Performance Implications." I examine relationships between social network structure, information structure, and individual performance. I build and validate a Vector Space Model of information diversity, develop hypotheses linking two key aspects of network structure - size and diversity - to the distribution of novel information among actors, and test the theory using data on email communication patterns, message content and performance. Results indicate that access to diverse, novel information is related to network structure in non-linear ways, and that network diversity contributes to performance even when controlling for the positive performance effects of access to novel information, suggesting additional benefits to network diversity beyond those conferred through information advantage.(cont.) Essay 3: "Organizational Information Dynamics: Drivers of Information Diffusion in Organizations." I examine drivers of the diffusion of different types of information through organizations by observing several thousand diffusion processes of two types of information -'event news' and 'discussion topics' - from their original first use to their varied recipients over time. I then test the effects of network structure and functional and demographic characteristics of dyadic relationships on the likelihood of receiving each type of information and receiving it sooner. Discussion topics exhibit more shallow diffusion characterized by 'back-and-forth' conversation and are more likely to diffuse vertically up and down the organizational hierarchy, across relationships with a prior working history, and across stronger ties; while news, characterized by a spike in communication and rapid, pervasive diffusion through the organization, is more likely to diffuse laterally as well as vertically, and without regard to the strength or function of relationships. The findings highlight the importance of simultaneous considerations of structure and content in information diffusion studies.by Sinan Aral.Ph.D

ICT Investment and Productivity: A Provincial Perspective

In 2008, Statistics Canada, for the first time, made available estimates of information and communication technology (ICT) investment by province. Given the importance of ICT investment for productivity growth, these data are important for the comparative analysis and understanding of productivity growth by province. The objective of this report is to present the basic data on ICT investment and ICT investment per worker in Canada and the ten provinces over the 1981-2007 period. The first part of the report reviews the literature on why ICT investment is important for productivity. The second part examines ICT investment levels and trends by province. The third part decomposes the gap in ICT investment per worker by province, relative to the national average, into three effects: that related to income levels, to the total investment/GDP share, and to the ICT investment/total investment share.Machinery and equipment investment, information and communications technology, ICT, Investment gap, Business sector, Provincial estimates

The Canada-US ICT Investment Gap: An Update

In 2005, the CSLS published a report that examined spending on information and communication technology (ICT) in Canada and the United States between 1987 and 2004. It found that Canadian firms lagged considerably behind US firms in ICT spending and that this situation accounted to some extent for the lower labour productivity growth experienced in Canada. This report provides an overview of the latest developments using the most recent update of the CSLS ICT database. It finds that ICT investment spending in the United States in 2005 and 2006 continued to outpace that in Canada, increasing an average of 5.6 per cent annually in the United States compared to 3.3 per cent in Canada when expressed in current dollars. Following this trend, nominal ICT investment per worker in domestic currencies also grew faster in the United States than in Canada in 2005 and 2006, 3.7 per cent versus 1.6 per cent. The recent increase in the Canadian dollar, however, lead to a sharper decrease in ICT prices in Canada than in the United States over the 2004-2006 period. This in turn led to an increase in the level of PPP-adjusted ICT investment per worker in Canada relative to the United States from 56.5 per cent in 2004 to 58.0 per cent in 2006, continuing the positive trend started in 2000 when it stood at 49.0 per cent. While Canada’s steady relative improvement since 2000 in terms of ICT investment per worker is encouraging, the low relative level of ICT investment per worker remains problematic and should be of concern to policy-makers as ICT investment is a key driver of productivity growth.Machinery and equipment investment, information and communications technology, ICT, Investment gap, Business sector, Industrial structure, Firm size

Social Incentives in the Workplace

We present evidence on social incentives in the workplace, namely on whether workers' behaviour is affected by the presence of those they are socially tied to, even in settings where there are no externalities among workers due to either the production technology or the compensation scheme in place. To do so, we combine data on individual worker productivity from a firm's personnel records with information on each worker's social network of friends in the firm. We find that compared to when she has no social ties with her co-workers, a given worker's productivity is significantly higher when she works alongside friends who are more able than her, and significantly lower when she works with friends who are less able than her. As workers are paid piece rates based on individual productivity, social incentives can be quantified in monetary terms and are such that (i) workers who are more able than their friends are willing to exert less effort and forgo 10% of their earnings; (ii) workers who have at least one friend who is more able than themselves are willing to increase their effort and hence productivity by 10%. The distribution of worker ability is such that the net effect of social incentives on the firm's aggregate performance is positive. The results suggest that firms can exploit social incentives as an alternative to monetary incentives to motivate workers

Got Technology? The Impact of Computers and Cell-phones on Productivity in a Difficult Business Climate: Evidence from Firms with Female Owners in Kenya

Firms in Kenya rely on technologies such as computers, cell-phones, and generators to overcome constraints associated with regulations, infrastructure, security, workforce, corruption, and finance. This study shows that such reliance has significant positive impacts on productivity as measured by value-added per worker, especially for firms with female principal owners. The exogenous component of technology ownership is isolated by using information on the regional presence of missionary schools from Kenya’s colonial past, as well as geographical indicators such as rainfall, changes in forest cover, and average regional elevation. Results indicate that for firms with female owners, technology adoption improves value-added per worker by about 49 percentage points. It is also statistically evident that for such firms, the ownership of technologies such as computers, cell-phones, and generators succeeds in mitigating the costs of business obstacles. For male-owned firms, such patterns are absent.Technology, Computers, Cell-phones, Business Obstacles, Kenya, Firms, Female Owners

Innovation, R&D and Productivity in the Costa Rican ICT Sector: A Case Study

This paper addresses the relationships between innovation, research and development (R&D) and productivity in domestic ICT firms in Costa Rica. Factors considered were the types of innovation outputs produced by domestic ICT firms, the relative importance of innovation inputs, the impacts of innovation on firm productivity, the protection of innovations, and impediments to innovation. While most firms engaged in all types of output and input innovations, they appear to be driven by retaining or increasing market share rather than increasing productivity. Half of firms do not formally protect the intellectual property created by their innovations, are not familiar with methods for protecting innovation or the availability of government grants for such purposes, and face barriers associated with the Costa Rican Patent Office. Other impediments include lack of knowledge about financial resources available and scarcity of human resources. There is also evidence of knowledge spillovers through worker mobility from multinationals operating in Costa Rica to domestic ICT firms.Research and development, Information communications technology, Innovation, Costa Rica
