In modern economies, networks play an important role in activities starting from information gathering to buying a product and making a policy decision by the government. This course on networks will focus on social and economic aspects of such networks. Networks have been studied for a long time by many researchers, especially in fields like mathematics, sociology and physics. However, much of this literature takes the network as given. It focuses on the structural properties of these networks like centrality measures, interaction between nodes in the networks and how the network can serve as a conduit for goods, services and even diseases. The game-theoretic approach to networks asks a different and important question. It asks how these networks get formed in the first place as a result of deliberate human behavior. In particular a key set of questions are: When are such networks stable? When are they efficient? Do these always coincide, and if not, what can we do to address this. Insights from this will help us understand who connects with whom and why. It will answer questions about how alliances between groups and nations form or how R&D collaborations arise between firms. Since networks play such a key role in the socioeconomic sphere, understanding the formation of multiple layers of networks will provide insights about intergenerational transmission of socioeconomic outcomes. The course will begin by motivating the study of networks with a brief and idiosyncratic history and the role they play in our lives. Then we will introduce concepts from graph theory and game theory necessary for the study of networks. Next, strategic or game-theoretic models of network formation will be covered. This will be followed by studying some applications of networks. Finally, the course will introduce multigraphs from a game-theoretic perspective.
