Vor dem Hintergrund der bisherigen theoretischen und empirischen Studien untersucht diese Arbeit vornehmlich die kausale Beziehung zwischen ausländischen Direktinvestitionen (DI) und Wirtschaftswachstum in 6 lateinamerikanischen Ländern.Die wachsenden Zuflüsse ausländischer...

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...

Chapter 1: Optimal Long-Run Inflation with Occasionally-Binding Financial Constraints.This paper studies the optimal inflation rate in a simple New Keynesian model with occasionally-binding collateral constraints that intermediate-good firms face on hiring labor. For empirically-relevant degrees...

In this dissertation, I further explore the role of the entrepreneurial sector in creating frictions in the economy. I examine the combined effect of private information and entrepreneurial risk aversion on the dynamics of a general equilibrium macroeconomic model. I analyze the impact of these...

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...
