The Balassa-Samuelson model, which explains real exchange rate movements in terms of sectoral productivities, rests on two components. First, the model implies that the relative price of non-traded goods in each country should reflect the relative productivity of labour in the traded and...

This paper presents a compact derivation of the determinants of changes in the equilibrium real exchange rate (the price index of non-traded goods relative to traded goods) in a small open economy with any number of goods and factors. It is shown that the change in the real exchange rate equals...

Originally propounded by the 16th-century scholars of the University of Salamanca, the concept of purchasing power parity (PPP) was revived in the interwar period in the context of the debate concerning the appropriate level at which to re-establish international exchange rate parities. Broadly...

This paper analyses the properties of multivariate tests of purchasing power parity (PPP) that fail to take heterogeneity in the speed of mean reversion across real exchange rates into account. We compare the performance of homogeneous and heterogeneous unit root testing methodologies. The...

This Paper analyses purchasing power parity (PPP) for the euro area. We study the impact of the introduction of the euro in 1999 on the behaviour of real exchange rates. We test the PPP hypothesis for a panel of real exchange rates within the euro area over the period 1973-2003. Our methodology...

In this paper we propose a new way to formulate optimal policy based on a quadratic intertemporal welfare function where the dynamic constraint is based on a VAR model of the economy which we call the PVAR method. We argue that the VAR under control should not be derived simply by replacing the...

The problem introduced by grouping income data when measuring socioeconomic inequalities in health (and health care) has been highlighted in a recent study. We reexamine this issue and show there is a tendency to underestimate the concentration index at an increasing rate when lowering the...

This paper presents an innovative approach to extracting factors which are shown to predict the VIX, the S&P 500 Realized Volatility and the Variance Risk Premium. The approach is innovative along two different dimensions, namely: (1) we extract factors from panels of filtered volatilities - in...

This paper empirically evaluates the effects of antidumping measures on the exports of protected firms. While antidumping protection raises the domestic sales of the more “traditional” non-exporting firms on the protected market with about 5%, it negatively affects the firm-level exports of...

A theoretical model for growth or inflation should be able to reproduce the empirical features of these variables better than competing alternatives. Therefore, it is common practice in the literature, whenever a new model is suggested, to compare its performance with that of a benchmark model....
