Approximate variational inference for a model of social interactions

Mele, Angelo - NET Institute - 2013

This paper proposes approximate variational inference methods for estimation of a strategic model of social interactions. Players interact in an exogenous network and sequentially choose a binary action. The utility of an action is a function of the choices of neighbors in the network. I prove...

Dynamic Platform Design

Veiga, Andre - NET Institute - 2014

Abstract I model dynamic product design along price and non-price dimensions by a firm in a market with positive network externalities between consumers. In the case of a usage fee, I provide conditions under which the steady state (SS) is unique and show that the introductory price is negative...

Estimating Causal Installed-Base Effects: A Bias-Correction Approach

Narayanan, Sridhar; Nair, Harikesh S. - NET Institute - 2011

New empirical models of consumer demand that incorporate social preferences, observational learning, word-of-mouth or network effects have the feature that the adoption of others in the reference group - the Òinstalled-baseÓ - has a causal effect on current adoption behavior. Estimation of...

Social Ties and User Generated Content: Evidence from an Online Social Network

Hoffstetter, Reto; Nair, Harikesh; Shriver, Scott; … - NET Institute - 2009

We use variation in wind speeds at surfing locations in Switzerland as exogenous shifters of users' propensity to post content about their surfing activity onto an online social network. We exploit this variation to test whether users' social ties on the network have a causal effect on their...

Revealed Preference Tests of Network Formation Models

Chiong, Khai Xiang - NET Institute - 2013

This paper proposes a revealed preference test of network formation models. Specifically, I consider network formation models where agents are (1) strategic, (2) externalities are confined to within an agentâ€™s k-neighborhood, where k can be varied. I show that this model can be tested...

Migration Between Platforms

Biglaiser, Gary; CreÌmer, Jacques; Veiga, AndreÌ - NET Institute - 2013

We develop a model of dynamic platform formation under positive platform externalities. Users can switch between an incumbent and entrant platforms, switching opportunities arise stochastically and users can choose whether to accept or reject an opportunity to switch. For homogeneous users, we...

Optimal Consumer Network Structure Formation under Network Effects: Seeds Controllability and Visibility

Dou, Yifan; Niculescu, Marius Florin; Wu, Dongjun - NET Institute - 2011

Understanding the process of software adoption is of paramount importance to software start-ups. We study a monopolistic seller’s optimal consumer network structure formation (seeding, segmentation, sequencing, and pricing strategies) under network effects. We demonstrate the importance of...

Multidimensional Heterogeneity and Platform Design

Veiga, Andre; Weyl, E. Glen - NET Institute - 2011

One of the most salient issues faced by platforms like newspapers and credit card issuers is that users are heterogeneous in the value they bring to other users or to the platform. We develop a model with multi-dimensional heterogeneity where a monopoly platform chooses (price or non-price)...
