The Distinct Effects of Information Technology and Communication Technology on Firm Organization

Guided by theories of "management by exception," we study the impact of information and communication technology on worker and plant manager autonomy and span of control. The theory suggests that information technology is a decentralizing force, whereas communication technology is a centralizing force. Using a new data set of American and European manufacturing firms, we find indeed that better information technologies (enterprise resource planning (ERP) for plant managers and computer-assisted design/computer-assisted manufacturing for production workers) are associated with more autonomy and a wider span of control, whereas technologies that improve communication (like data intranets) decrease autonomy for workers and plant managers. Using instrumental variables (distance from ERP's place of origin and heterogeneous telecommunication costs arising from regulation) strengthens our results.
