On the Relevance and Nature of Regional Inflation Differentials: The Case of Spain

This paper studies two aspects of the behaviour of provincial relative prices in Spain: the relevance and the nature of provincial inflation divergences and relative price shifts. Inflation differentials are found to be small (the range is less than half point per year in the long-run), but deviations of relative prices from equilibrium can be very persistent.

Internal and External Exchange Rate Equilibrium in a Cointegration Framework. An Application to the Spanish Peseta

Abstract. A simple cointegration methodology is used to compute the equilibrium real exchange rate for the peseta. The stock of foreign assets and the evolution of sectoral prices are considered to be the fundamentals for the real exchange rate. After testing for cointegration, we proceed to decompose the series into a permanent and a transitory component, following the method devised by Gonzalo and Granger. The permanent component of the real exchange rate corresponds to its (time-varying) equilibrium value, and the deviation of the actual real exchange rate from this equilibrium value gives an estimation of the degree of misalignment of the real exchange rate. By the end of the sample (1998:1), the peseta is estimated to be undervalued around 6%.

Equilibrium Exchange Rates in New EU Members: External Imbalances versus Real Convergence

New EU members share two very marked features which have conflicting implications for the evolution of their real exchange rates in the long run: accelerated growth and systematic current account imbalances, which would anticipate, respectively an appreciation and a depreciation of their currencies, according to different theories of exchange rate determination. Furthermore, both elements are intertwined, for current account imbalances are the other side of capital inflows which have been central in boosting potential output and productivity convergence in these economies. In this paper, we aim at achieving some insight on the role of persistent and substantial capital inflows and the consequent accumulation of net foreign liabilities in improving competitiveness and in the determination of the exchange rate for the three largest new EU members: Poland, Hungary and the Czech Republic. We adopt a sequential approach that sheds light on the role of capital flows and their interaction with the Balassa-Samuelson hypothesis. We start by noting in a bivariate cointegration analysis that the accumulation of net foreign liabilities, far from depressing the exchange rate in the long-run, has gone hand-in-hand with exchange rate appreciation. We claim that this may be due to the induced effect that capital inflows are expected to have on productivity and competitiveness. After testing that foreign direct investment is cointegrated with productivity trends, we show that a extended empirical model comprising relative productivity and net foreign assets is well-suited in general to capture this indirect, opposite effect of liabilities accumulation on the real exchange rate. Finally, the model makes it possible to estimate for the considered countries equilibrium exchange rates and misalignments and perform some simulations on their expected future path.

On the Evolution of Relative Prices and Its Nature at the Regional Level: The Case of Spain

This paper studies the relevance and nature of shifts in relative prices at the regional level in Spain. Deviations in relative prices tend to be small (at most half a point of inflation annually) but persistent. They are determined by features intrinsic to deep economic integration, in particular, wage mechanisms operating at the national level. This is in stark contrast to evidence at the international level. Therefore, while acknowledging that divergent price evolutions are possible in the European Monetary Union, their nature will be different from those observed among Spanish regions.
