Social network effects on information aggregation
In this thesis, we investigated how sociometric information can be used to improve different methods of aggregating dispersed information. We specifically compared four different approaches of information aggregation: vanilla opinion poll, opinion polls where sociometric data is inferred from the …

Three Essays on Network Effects in Online Social Networks
In my dissertation, I focus on estimating network effects in online social networks, using observational data. In the first chapter of my dissertation, coauthored with David Easley and Eleonora Patacchini, we analyze the effect of peer influence on item adoption decisions on GitHub. The second …

Network Effects on Outcomes and Unequal Distribution of Resources
We focus on the link between networks and economic outcomes, study how networks affect different groups differently and in the process provide pathways to reinforce existing inequalities. First, we establish the link between the economic well-being and the network structure of US counties. We show …

Network effects on the internationalization process of Icelandic Software Firms
… reach market niches across the globe. The use of network relationships can help firms to skip stages in the internationalization processes and link together resources or reach market niches that are not available domestically. Problem Many studies have pointed out the influence of network …

The Market For Electric Vehicles: Indirect Network Effects And Policy Impacts
… new technology. The EV market features indirect network effects (or the chicken-and-egg problem) in that consumers may be reluctant to adopt EVs with the lack of public charging stations while investors are less willing to build charging stations when the installed base of EVs is small. Indirect …

Diffusion of ideas, practices, and artifacts : network effects on collective outcomes
… is significantly related to the communities' network of advice. The adoption of an idea, practice or artifact is heavily influenced by social context, through both conscious and unconscious mechanisms. By targeting social networks, not social classes, age, gender groups or institutions, we can …

An analysis of interconnection network effects of dynamic element matching digital-to-analog converters
… is a method that can eliminate or reduce the effects of mismatch errors. In this thesis, DEM algorithms applied to a specific DEM DAC architecture that use several interconnection networks, including the Barrel Shifting network, the Generalized-Cube network, the Omega network and the Indirect …

Producer Network Effects for Rural Economic Development: An Investigation into the Economic Development Potential of Information Production as a Firm-Level Effect of Broadband Telecommunications in Rural Areas
… is being invested in the deployment of broadband networks based, at least in part, on the premise that economic development benefits will obtain. However, there is a general lack of academic theory explaining the mechanism(s) by which broadband telecommunications can produce economic development …

Airline fleet assignment and schedule design : integrated models and algorithms
… assignment problem, we investigate the issues of network effects, spill, and recapture. On a constrained flight leg in which demand exceeds capacity, some passengers are not accommodated, or spilled. When passengers travel on two or more constrained legs, flight leg interdependencies or network …

Determinants of international migration
… migrant stock to capture partial adjustment and network effects. To correct for the dynamic panel data bias of the fixed effects estimator a bootstrap algorithm is used. The results indicate that immigrants are primarily attracted by better income opportunities and higher growth rates abroad. …

Understanding Drivers of Deforestation using Games on Spatial Networks
… engage in coupled activities over a spatial network and study a policy intervention to limit illegal deforestation. Firstly, we conduct equilibrium analysis of a game in which each agent decides the production levels of her coupled activities in the presence of network effects. Practically, …

Sensing and Predicting Urban Rail Platform Crowding Using Emerging Data Sources
… time series modeling framework by incorporating network-wide causal influences through an analysis driven by Empirical Dynamic Modeling and Convergent Cross Mapping. We show that accounting for network effects improves predictive performance, particularly for platforms characterized by regular …

Unified communications : convergence of platforms and strategies of two software vendors
… firms within the UC market. The theory of network effects originally developed by Rohlfs is central to the analysis in this thesis. The analysis of platform strategies of the UC firms is informed by the theoretical work on platform leadership (Gawer & Cusumano), convergence (Greenstein et …

How should we measure the digital economy?
… in the US. Chapter 3 proposes a way of measuring network effects on multi-sided platforms using choice experiments. It also models digital platforms allowing for heterogeneity in demand elasticity and network effects across users of different types. It then calibrates the model using an empirical …
