I study the evolution of aggregate volatility in the US during the postwar period by assessing the relative role played by financial shocks, technological progress, and changes in the financial system. Balance-sheet variables of firms have been characterized by greater volatility since the early...

This thesis explores the important link between macroeconomic dynamics and the financial sector. The first essay studies Epstein-Zin preferences, which are found to be able to account for both aggregate macroeconomic dynamics and asset prices. In the first essay, I compare different solution...

Developing country fiscal policy outcomes documented in data point to stark differences compared with developed ones. Most prominent difference is the excessive volatility of government consumption and transfer payments and their positive correlation relative to output. This seemingly...

Unlike the prediction of a frictionless open economy model, long-term average savings and investment rates are highly correlated across countries—a puzzle first identified by Feldstein and Horioka (1980). We quantitatively investigate the impact of two types of financial frictions on this...

This paper studies the famous Feldstein and Horioka finding, which is a high correla-tion between long period averages of savings rates and investment rates across countries. We first confirm the Feldstein-Horioka finding with a more recent data set, and then show that a calibrated complete...

We postulate a nonlinear DSGE model with a financial sector and heterogeneous households. In our model, the interaction between the supply of bonds by the financial sector and the precautionary demand for bonds by households produces significant endogenous aggregate risk. This risk induces an...

En este trabajo se comparan dos metodologías macroeconómicas punteras pero a la vez muy distintas: el modelo DSGE con expectativas racionales y el modelo de comportamiento con racionalidad limitada. Procedemos a ampliar los dos para incluir fricciones financieras por el lado de la oferta...

En este trabajo se contrastan las predicciones teóricas del modelo elaborado por Duca, Montero, Riggi y Zizza (2017). Este es un modelo de mercados de clientes (customer markets) con costes de cambio de proveedor (switching costs) e imperfecciones en los mercados de capitales, en el cual los...

¿Cuáles son los efectos de una burbuja inmobiliaria sobre el resto de la economía? En este trabajo mostramos que, si las empresas y los bancos están restringidos, una burbuja inmobiliaria inicialmente reduce el crédito a empresas no relacionadas con el sector inmobiliario. Esto es así...

Este trabajo analiza el impacto que la incertidumbre acerca de las políticas económicas tiene sobre las decisiones de inversión de las empresas. Para ello se hace uso de una muestra de gran tamaño de empresas no financieras españolas, para el período 1998-2014. La incertidumbre se mide...
