    Innovating without Information Constraints: Organization, Communities, and Innovation when Information Costs Approach Zero

    Elizabeth J. Altman, Frank Nagle and Michael Tushman

    Innovation has traditionally taken place within an organization's boundaries and/or with selected partners. This Chandlerian approach to innovation has been rooted in transaction costs, organizational boundaries, and information processing challenges associated with distant search. Information processing, storage, and communication costs have long been an important constraint on innovation and a reason for innovative activities to take place inside the boundaries of an organization. However, exponential technological progress has led to a dramatic decrease in information constraints. In a range of contexts, information costs approach zero. In this chapter, we discuss how sharply reduced information costs enable organizations to engage with communities of developers, professionals, and users for core innovative activities, frequently through platform-based businesses and ecosystems and by incorporating user innovation. We then examine how this ease of external engagement impacts the organization and its strategic activities. Specifically, we consider how this shift in information processing costs affects organization boundaries, business models, interdependence, leadership, identity, search, and intellectual property. We suggest that much of the received wisdom in these areas of organization theory requires revisiting. We then discuss the implications for an organization's management of innovation and conclude with research opportunities.

    Crowdsourced Digital Goods and Firm Productivity: Evidence from Open Source Software

    As firms increasingly rely on crowdsourced digital goods, understanding their impact on productivity becomes critical. This study measures the firm-level productivity impact of one such good, non-pecuniary (free) open source software (OSS). The results show a previously unmeasured positive and significant return to the usage of non-pecuniary OSS that is not solely due to cost savings. Inverse probability weighting, instrumental variables, firm fixed effects, and management quality data add support for a causal interpretation. Across firms, a 1% increase in non-pecuniary OSS leads to a .073% increase in productivity or a $1.35 million increase in value-added production for the average firm in the sample. This effect is greater for larger firms and for firms in the services industry. These findings indicate that existing studies underestimate the amount of IT firms use and suggest that firms assuming the risks associated with non-pecuniary OSS gain benefits from collective intelligence and labor spillovers.
