Using the new unit root test by Phillips et al. (2011) we show that the Target balances of the German Bundesbank have been exploding from the beginning of 2009 to the beginning of 2013. By implementing a full-allotment policy and reducing the required minimum quality of collaterals in October...

We implement a two-step analysis of fiscal and external causality patterns using a data set covering the 27 EU countries in the period 2002Q1-2023Q4. In the 1st step, we compute fiscal and external sustainability time-varying coefficients, modelling the cointegration relationship between...

We present a unified dynamic framework to study the interconnections between international trade and business cycle models. We prove an aggregate equivalence between a competitive, representative firm model that has aggregate production externalities and dynamic trade models that feature...

Over the last decade foreign bond portfolio positions in US dollar assets have risen above the reciprocal US investor positions in foreign currencies. In periods of increased economic uncertainty, institutional investors hedge their international bond positions, which creates a net hedging...

We propose a new channel through which exchange rates affect trade. Exploiting the heterogeneity in firms' foreign currency debt maturity structure around a large depreciation in Colombia, we show that debt revaluation compresses imports due to higher delinquencies and interest rates, while...

This paper studies the spillovers of US monetary policy and the mitigating role of foreign exchange interventions (FXI) by combining deviations from a daily FXI policy rule with high-frequency US monetary policy shocks, daily exchange rates, and firm-level stock prices, as well as firm-level...

This paper examines the impact of exchange rate uncertainty on different components of portfolio flows, namely equity and bond flows, as well as the dynamic linkages between exchange rate volatility and the variability of these two types of flows. Specifically, a bivariate GARCH-BEKK-in-mean...

We study the renminbi (RMB) covered interest differential - an indicator of the effectiveness of capital controls. It is found that the differential is not shrinking over time and, in fact, appears larger after the global financial crisis than before. That is, capital controls in China are still...

This paper applies the NATREX model of equilibrium exchange rates to evaluate several key studies of the Central and Eastern European Countries (CEEC) in general, with particular emphasis upon the Czech Republic and Hungary and with references to Poland and Bulgaria. On the basis of the NATREX...

In this paper we test the well-known hypothesis of Obstfeld and Rogoff (2000) that trade costs are the key to explaining the so-called Feldstein-Horioka puzzle. Using a gravity framework in an intertemporal context, we provide strong support for the hypothesis and we reconcile our results with...
