This chapter analyses the architecture of the International Monetary System (IMS) and the role of reserve currencies in it. We begin by describing the evolution of the IMS from the Gold Standard to the Bretton Woods system and the European integration process that led to the creation of the...

Economic theory and empirical evidence suggest that fluctuations in exchange rates may have strong reallocation effects. Accession to the Exchange Rate Mechanism in 1992, and then to the European Monetary Union in 1999, implied a drastic change in the behaviour of Portugal's exchange rate...

Real exchange rate movements are important drivers of the reallocation of resources between sectors of the economy. Economic theory suggests that the impact of exchange rates should vary with the degree of exposure to international competition and with the technology level. This paper...

We evaluate the macroeconomic performance of different monetary policy rules when there is exchange rate uncertainty. We do this in the context of a non-linear rational expectations model. The exchange rate is allowed to deviate from its fundamental value and the persistence of the deviation is...

We analyse the effect of uncertainty concerning the state and the nature of asset price movements on the optimal monetary policy response. Uncertainty is modeled by adding Markov-switching shocks to a DSGE model with capital accumulation. In our analysis we consider both Taylor-type rules and...

This paper argues that nonlinear adjustment may provide a better explanation of fluctuations in the consumption-wealth ratio. The nonlinearity is captured by a Markov-switching vector error-correction model that allows the dynamics of the relationship to differ across regimes. Estimation of the...

The rise of nontradable sectors has been mentioned as one of the causes of low economic growth and external imbalances in the Portuguese economy. In this paper we describe the main trends and jumps in the evolution of nontradable sectors, since the mid-1950s, using four different databases to...

This paper analyses the spread of the sovereign debt crisis in the Eurozone. To this end we employ three approaches. The first approach employs univariate autoregressive models. These allow the identification of shocks to government bond yields in Portugal, Italy, Ireland, Greece, Spain and...

There is increasing evidence that the interaction between shocks and labour market institutions is crucial to understanding the dynamics of employment. In this paper, we show that the inclusion of labour adjustment costs in a trade model affects the impact of exchange rate movements on...

Integration into the world economy, specialization in low-technology sectors and labour market rigidity have been singled out as structural features of the Portuguese economy that are crucial for the understanding of its performance. In this paper, we explore empirically the role of openness,...
