Estimating peer effects in noisy, low-rank networks via network smoothing

Peer effect estimation requires precise network measurement, yet most empirical networks are noisy, rendering standard estimators inconsistent. To address measurement error in networks, we propose a method to estimate peer effects in networks whose expected adjacency matrix is low-rank. Our key result shows that peer effects over a true unobserved network are asymptotically equivalent to peer effects over the expected adjacency matrix. This result reduces peer effect estimation in noisy networks to low-rank matrix estimation targeting the expected adjacency matrix. We develop our theory for weighted networks observed with additive noise, but simulations suggest approach can be applied more generally when there is a low-rank estimation method suited to a particular noise structure. We demonstrate via simulations that our approach applies to egocentric samples, aggregated relational data, and networks with missing edges, each requiring a different low-rank estimation method.

The Wealth of Networks

The Wealth of Networks: How Social Production Transforms Markets and Freedom is a book by Harvard Law School professor Yochai Benkler published by Yale University Press on April 3, 2006. The book has been recognized as one of the most influential works of its time concerning the rise and impact of the Internet on the society, particularly in the sphere of economics. It also helped popularize the term Benkler coined few years earlier, the commons-based peer production (CBPP).

Seize the Means of Computation - ProMarket

To regain internet autonomy from Big Tech companies, lower switching costs with legislation that allows new services to subvert network effects and encourage adversarial interoperability. Too often, our discussion of Big Tech’s dominance starts and ends with a simplistic account of network-effects-driven inevitability, as though the winner-take-all market we have today could not have been […]

Open Source infrastructure deserves a business model

Open Source infrastructure is essential, invisible, and chronically underfunded. A more sustainable approach may be to connect the cost of running that infrastructure to the organizations that rely on it most.

Open Up Vs Break Up - AVC

There have been many calls to break up the large Internet monopolies; Amazon, Google, Facebook, Apple, etc. Breaking up a large monopoly feels like a very 19th/20th century move to me. I would prefer that politicians and policy makers think about opening up as the better intervention. A good way to explain this is to […]
