We show how networks modify the diffusion curve by affecting its symmetry. We demonstrate that a network's degree distribution has a significant impact on the contagion properties of the subsequent adoption process, and we propose a method for uncovering the degree distribution of the adopter...

In this paper, we propose an individual-level approach to diffusion and growth models. By , we refer to the unit of analysis, which is a single consumer (instead of segments or markets) and the use of granular sales data (daily) instead of smoothed (e.g., annual) data as is more commonly used in...

The Gini index is the most common method for estimating the level of income inequality in countries. In this article, we suggest a simple modification that takes into account the moderating effect of in-kind government benefits. Unlike other studies that use micro-level data that are rarely...

Firms' incentives to manufacture biased user reviews impede review usefulness. We examine the differences in reviews for a given hotel between two sites: Expedia.com (only a customer can post a review) and TripAdvisor.com (anyone can post). We argue that the net gains from promotional reviewing...

We use the formalism of “maximum principle of Shannon's entropy” to derive the general power law distribution function, using what seems to be a reasonable physical assumption, namely, the demand of a constant mean “internal order” (Boltzmann entropy) of a complex, self-interacting,...
