Description:
In the last two decades, economic analysis has gradually incorporated the network theory, broadening the standard microeconomic models by considering dependent agents in contexts of: game theory, social capital, labor and financial markets, productive networks and experiments. This thesis investigates two big topics about networks in economy: the interaction between accountants and taxpayers in firm’s tax reporting, and the diffusion of microeconomic shocks through input-output interrelations. The former is an empiric investigation that was carried out through an experiment for deterrent notifications on Ecuadorian tax system in 2016. Meanwhile, the latter is a theoretical investigation that analyzes the role of imperfect markets and firm bankruptcy through a novel microeconomic network model.
