Lost in intervention. The Harrod–Balassa–Samuelson effect on the peseta/dollar real exchange rate (1870–1998)

We have decomposed the peseta/dollar real exchange rate (1870–1998) into its trend and cyclical components and used the former to proxy its time-varying equilibrium. Then, we have compared changes in the equilibrium with changes in the Spanish and the USA productivity differentials to identify years that do not fit with the Harrod–Balassa–Samuelson (HBS) hypothesis. The greatest maladjustment is found in the 1940s and 1950s, decades of strong exchange rate intervention in Spain. Conversely, the link between equilibrium and differentials adjusts to the hypothesis when using the non-intervened peseta/dollar exchange rate on the Tangier black market. These contrasting results back up the idea that exchange rate intervention, so common in developing countries, might explain their scanter evidence in favour of the HBS effect.     

Does fiscal policy influence monetary policy? The case of Spain, 1874-1935

The Spanish peseta never formally belonged to the gold club, neither the classical nor the exchange-rate gold standards. It has been traditionally argued that the reason was the predominance of deficits in the Spanish budget from 1874 to 1935. The financing needs of the Treasury led to money creation and, consequently, to sacrificing the gold commitment and a fixed exchange rate. Applying a stationary VAR (Vector AutoRegressive) model, this paper estimates the dynamic link between budget and money and tests whether Spanish fiscal policy actually influenced monetary policy. The results confirm the dominance of fiscal policy for the period and, therefore, provide empirical support to the idea that the problems of the Treasury were behind Spain’s renouncement of gold.     

The effects of macroeconomic stability on foreign trade. An analysis for Spain, 1986–2000

Two main factors underlie the rebirth of interest in the study of the influence of the real exchange rate on trade, the reduction of its volatility and the current trend towards price stability. The objective of this study is to analyse the effects of the process of nominal convergence, required of the European member states for the fulfilment of monetary integration, on foreign trade flows. The case of Spain, which is especially interesting in this context, is studied for the period 1986 to 2000. The results of estimating the aggregate functions of the export and import of goods shows how macroeconomic stability has altered the behaviour of trade with respect to the two basic determinants – income and prices – how it has caused a significant structural change in the real exchange rate and, finally, how it has laid the explanatory bases for transactions in the twenty-first century with the single currency – the euro.     

Aggregation is not the solution: the PPP puzzle strikes back

Recently, Imbs, Mumtaz, Ravn and Rey (2005, hereinafter IMRR) have argued that much of the purchasing power parity (PPP) puzzle is due to upwardly biased estimates of persistence. According to them, the source of the bias is the existence of heterogeneous price adjustment dynamics at the sectoral level that established time series or panel data methods fail to control for. This paper re‐examines this claim in two steps. Firstly, we demonstrate that IMRR's measures of sectoral persistence are systematically downwardly biased because they are based on an inaccurate definition of the ‘average’ impulse response function (IRF). We then show that standard estimates of shock persistence are recovered after this bias is corrected. Secondly, building on the results in Mayoral (2008), which prove that aggregate and micro models induce the same shock persistence behavior, we show that estimates based on aggregate and sectoral exchange rates are, in fact, highly consistent. Thus, aggregation is not the solution to the PPP puzzle. Copyright © 2009 John Wiley & Sons, Ltd.     

European monetary integration and persistance of real exchange rates

The aim of this paper is to analyze whether the persistence properties of the European real exchange rates changed when their currencies joined the euro or during the monetary integration process. More specifically, we investigate whether, as a result of the single currency or the previous macroeconomic stability, nominal price rigidities have decreased and the persistence of real exchange has fallen. We test for stationarity against a change in the integration order on different competitiveness measures during the period that runs from the middle of the seventies to nowadays. The results show that the real exchange rates of the European periphery (Spain, Italy, Portugal, Greece and Finland) underwent a change in their order of integration from I(1) to I(0) at some time around the middle of the 1990s. On the other hand, the real exchange rates of the Central European countries, with a greater stability in the 1980s and 1990s, changed their integration order earlier, if at all, mostly during the 1980s. So, the euro seems to have had, on the whole, little influence on the persistence of real exchange rates. Only for a few countries do our findings detect a significant decrease in persistence related with the nominal convergence process.     

The European Union currencies and the US dollar: from post-Bretton-Woods to the Euro

In this paper we study the evolution of the US dollar real exchange rate vis-à-vis the European Union currencies in the floating post-Bretton-Woods era, both before and after the birth of the Euro. In the first period we find that most of the persistence shown by this rate is due to the movements of the US dollar during the mid-1980s. Once these effects are isolated, we can conclude that the US dollar real exchange rate exhibits stationarity with those currencies that are closely linked to the German Mark. However, when we include the observations covering the period during which the Euro was created, we cannot reject the unit root null hypothesis for any currency.     

The European Periphery in the Era of the Gold Standard: The Case of the Spanish Peseta and the Pound Sterling from 1883 to 1931

This paper analyses the relationship between the Spanish peseta, the currency of a peripheral country, and the pound sterling, the central currency of the gold standard. From 1883, when Spain suspended metallic convertibility, until 1931, when Great Britain definitively abandoned gold, the peseta was a fiat currency with a flexible exchange rate regime. Our results confirm, first, long-run PPP hypothesis compliance for the peseta/pound sterling rate during the period. Secondly, we illustrate how the inclusion of peripheral variables (erratic trade and financial risk), significantly improves the short-run adjustment to the PPP hypothesis. It appears that the floating regime thus helped Spain to smooth out the required external adjustment process resulting from balance of payments shocks.     

Aggregate real exchange rate persistence through the lens of sectoral data

A novel approach to analyzing real exchange rate (RER) persistence and its sources is presented. Using highly disaggregated data for a group of EU-15 countries, it is shown that the distribution of sectoral persistence is highly heterogeneous and skewed to the right, so that a limited number of sectors are responsible for the high levels of persistence observed at the aggregate level. Quantile regression has been employed to investigate whether traditional theories, such as the lack of arbitrage due to nontradability or imperfect competition combined with price stickiness, are able to account for the slow reversion to parity of RERs.     

Exchange rate regimes and prices: The cases of Italy,Spain and the United Kingdom (1874–1998)

This paper studies the relationship among Italian, Spanish and United Kingdom prices over the period 1874–1998, for most of which the currencies of these three countries maintained a floating exchange rate regime. By using cointegration techniques with broken linear trends, we find a single vector for the period 1874–1935 and two vectors and, consequently, a single common trend for the period 1940–1998. Therefore, this paper provides new evidence of no long-run monetary independence under floating regimes. Furthermore, the price differential dynamics captured by deterministic trends in the period 1940–1998, as well as agreeing with the evidence of long-run transmission of interest rates in the floating post-Bretton Woods era, fit in perfectly with the new de facto taxonomies on exchange rates.     

The hidden economy in Spain – A monetary estimation, 1964–1998

The aim of this paper is to estimate the level and evolution of hidden income in Spain during the period 1964–1997. To this end, we employ the well-known monetary approach which supposes that the hidden economy is a response on the part of the economic agents to the tax burden, one which manifests itself in an excess of demand for currency. The estimation has been made on the basis of the ADL technique, an ECM and Johansen's cointegration approach. The period chosen was characterised by multiple institutional changes, an increase in the tax burden and wide-ranging financial liberalisation. This has obliged us to formulate a specific monetary model to estimate the hidden economy and is one of the original features of that model.
