Managing in the Presence of Hidden Influences

Michael D. Ryall and Olav Sorenson

Theoretical research on organizations generally presumes that their leaders have the ability to direct the organization towards a set of goals. But that presumption depends crucially on the ability of leaders to understand how particular actions or directives would influence organizational outcomes, a problem of causal inference. We develop a formal model of this problem. Our model reveals that hidden (unobserved) influences can stymie inference. However, these hidden influences only become problematic under a specific set of local conditions. That fact further suggests that organizational design features can help to mitigate this problem. We introduce three types of solutions to the problem of inference in the presence of hidden influences — experimentation, illumination, and substitution — and discuss how these solutions relate to a variety of organizational design features.

Entrepreneurship and gentrification

Luisa Gagliardi and Olav Sorenson

How do high-growth startups influence the neighborhoods in which they locate? Using data from the greater London area, we show a positive relationship between entrepreneurship and the subsequent growth of residential real estate prices in a neighborhood. These effects appear concentrated in places that had been cheaper prior to the entry of the entrepreneurs. The demographic composition of these communities also changes in a classic pattern of gentrification, with older, less educated residents being replaced by younger, more educated ones.
