We investigate into the role of the trade channel as important determinant of a country's current account position and the degree of business cycle synchronization with the rest of the world by comparing the predictions of two types of DGE models. It is shown that the behavior of a country's external balance and the international transmission of shocks depends amongst other things on two factors: i) the magnitude of trade interdependence, ii) the degree of substitutability between importable and domestically-produced goods. Using time series data on bilateral trade flows, we estimate the magnitude of trade interdependence and the elasticity of substitution between importable and domestic goods for the G7 countries. Given these estimates, idiosyncratic supply shocks potentially induce changes in the current account and foreign output that vary in direction and magnitude across G7 countries. The relationship between the magnitude of foreign trade and the import substitutability with various correlation measures is examined empirically in a cross-sectional dimension.

This dissertation contains three essays on monetary policy, dynamics of the interest rates and spillovers across economies. In the first essay I examine the effects of monetary policy and its interaction with financial regulation within a micro-founded macroeconometric framework for a closed economy with a heterogeneous banking system, facing a period of low interest rates. I analyse the interplay between monetary policy and banking regulation and study the role of agents’ expectations for the effectiveness of unconventional monetary policy tools. In the next essay, I argue that openness is crucial for understanding the dynamics of the term structure. In an empirical application, I show that my model of the term structure fits well the yield curve in-sample and has a sound ability to forecast interest rates out-of-sample. The model accounts for the expectations hypothesis, replicates the forward premium anomaly and reconciles the uncovered interest rate parity implications. The last essay is concerned with the dynamics of co-movement among macroeconomic aggregates and the degree of convergence or decoupling amongst economies. The model includes measures of financial and trade-based interdependencies and incorporates feedback between macroeconomic variables and time-varying weights. The findings point at the importance of asset price movements and financial linkages.
This thesis consists of four chapters. Each chapter covers a topic in international macroeconomics and monetary policy. The first chapter investigates the impact of unexpected monetary policy shocks on exchange rates in a multi-country econometric model. The second chapter examines the linkage between macroeconomic fundamentals and exchange rates through the monetary policy expectation channel. The third chapter focuses on the international transmission of bank and corporate distress. The last chapter unfolds the interest rate channel of monetary policy transmission in-an emerging economy-China, where regulations and market forces co-exist in this transmission.
