Domestic migration networks in the United States
… ties that link cities together, and what is the network structure formed by such ties? At the same time, human capital accumulation is increasingly seen as a, primary driver of regional economic growth. Domestic migration patterns have the potential to illuminate the social and economic …

Essays on Network formation games
This dissertation focuses on studying various network formation games in Economics. We explore a different model in each chapter to capture various aspects of networks. Chapter 1provides an overview of this dissertation. Chapter 2 studies the possible Nash equilibrium configurations in a model of …

Towards an Integrated Model of the Mental Lexicon
… that by representing the mental lexicon as a network, where nodes represent words and edges connect similar words using a metric based on some word feature, a <em>small-world</em> structure is formed. This property, pervasive in many real-world networks, implies processing efficiency and …

Node-weighted prize-collecting survivable network design problems
We consider node-weighted network design problems, in particular the survivable network design problem SNDP and its prize-collecting version PC-SNDP. The input consists of a node-weighted undirected graph $G=(V,E)$ and integral connectivity requirements $r(st)$ for each pair of nodes $st$. The goal …

Three Essays on Networks
… human behavior and contagion phenomenon in networks. The analysis especially focuses on information sharing, trade relationship and pest spread in networks. The first chapter outlines the dissertation by briefly discussing the motivations, methods, and main findings in each of the following …

Sports analytics and optimization for team formation problems
… context of sports. To begin, we develop a novel weighted network clustering algorithm to classify players in the National Basketball Association (NBA) into archetypes. Next, drawing upon classical Team Formation Problem (TFP) literature, we integrate these archetypes, or team roles, into a …

Three essays on econometrics: Network estimators with applications and assessment of the effects of Covid-19 pandemic
… first two of them, aims to develop estimators of network structures from observations of a random vector whose components represent the variables of interest and are the nodes in a network. The goal is to reconstruct a (weighted) graph when we are not able to directly observe connections among …

Toward a network graph-based innovation cluster density index
… an empirical analytical approach, using complex network theory, commercially and open source available application program interfaces (APIs), and weighted network graphs as a framework, which integrates these elements to depict a new descriptor for clusters, the Cluster Rank. Implementation of …

Statistical models and inference for dynamic networks
… often best understood within the framework of networks. Network data can vary in many ways. For example, one might have binary or weighted networks, directed or undirected networks, and static or longitudinal networks. This last type of network, also called a dynamic network, is the focus of …

Functional neuroimaging studies of peripheral inflammation-related depression
… proteins, i.e., cytokines and chemokines. Weighted network visualization, coupled with a literature search-based functional assignment of each biomarker, indicated that functionally-related inflammatory proteins were more strongly positively correlated with each other. Thus, concentrations …
