This thesis investigates the role of institutions in shaping macroeconomic phenomena. The first two chapters focus on financial institutions, formalizing interactions between information and competition in frictional credit markets and providing novel predictions for output and efficiency. The...

Fluctuation Economic research grow up from 80’s with the Dynamic Stochastic General Equilibrium Models (DSGE), where the agent are search for the optimum point at the intertemporal decisions, that is decision over time of how consumers make choice between present and future consumption at the...

This dissertation consists of two essays studying macroeconomics questions about labor markets. The research in this document is separated into chapters that study distinct features of aggregate labor market outcomes.The first essay documents the change in behavior of fertility rate at business...

Dynamic factor models (DFM) and dynamic stochastic general equilibrium (DSGE) models are widely used for empirical research in macroeconomics. The empirical factor literature argues that the co-movement of large panels of macroeconomic and financial data can be captured by relatively few common...
