In this paper we revisit the issue of currency regime choice for an independent Scotland using an international macroeconomic/ finance framework. Specifically, we consider the main competing proposals for currency choice with an emphasis on the SNP’s official policy of the informal use of sterling post-independence. We conclude that from a macroeconomic perspective this option is unlikley to be credible to international capital markets. The option that would be credible, and avoids the austerity associated with the choice of a fixed exchange rate option, would be a free float at least during the transition period of independence.

Devaluations were traditionally considered to be expansionary in the short run and have no real long-run effects. Alternatively, some observers in developing countries found that devaluations were contractionary on impact, and that they might foster long-term growth. Using Argentina as a case study, which is convenient due to its long series availability and its subsequent switches in exchange rate regimes, four structural shocks are identified in line with the traditional and alternative views. It is found that devaluations were mostly contractionary, and that real long-run effects were only possible when inflation was either low or moderate. In light of the estimates, a historical revision of Argentinean devaluation episodes from 1854 to 2018 has been carried out.

Based on the reconstruction of the monetary flows of a merchant-banking company operating in Barcelona at the beginning of the fifteenth century, this study aims to understand the reasons behind exchange-rate variations in the local currency with respect to the principal European markets, as well as the modalities and predictability of such oscillations. By using real rather than ‘hearsay’ rates, we present new assessments of the seasonal character of exchange rates and their sensitivity to conditions of currency abundance or shortage. In addition, econometric analysis shows that exchange-rate volatility was quite modest and dependent on geographic and macroeconomic factors, such as the system of commercial flows.

This article studies the financial market integration in the 1670s by examining the effectiveness of triangular exchange arbitrage. The results suggest that international credit markets based on bills of exchange in northwestern Europe were well integrated and responded to exchange-rate differences quickly. The speed of adjustment, ranging between one and three weeks, accorded with the speed of communication, but the transaction cost associated with exchange arbitrage was much lower than that of shipping bullion. Although warfare had a disruptive effect on exchange arbitrage by increasing transaction cost, markets were resilient in remaining efficient.

Following the pioneering work of Irving Fisher, this article assesses the uncovered interest-parity (UIP) condition by comparing Indian interest and exchange rates during the 1869 to 1906 period. The Indian case provides a good example of the UIP condition, since Indian rupee and sterling bonds were simultaneously traded in the London financial market and subject to negligible default risks. Large deviations from the UIP condition arose when India suffered from pervasive levels of uncertainty about the future of its silver-based currency system. Otherwise, a relatively close correlation arises between sterling-to-rupee interest-rate differences and exchange-rate changes.

In December 1933, John Maynard Keyes published an open letter to President Roosevelt, where he wrote: ‘The recent gyrations of the dollar have looked to me more like a gold standard on the booze than the ideal managed currency of my dreams.’ This was a criticism of the ‘gold-buying program’ launched in October 1933. In this article I use high-frequency data on the dollar–pound and dollar–franc exchange rates to investigate whether the gyrations of the dollar were unusually high in late 1933. My results show that although volatility was pronounced, it was not higher than during some other periods after 1921. Moreover, dollar volatility began to subside towards the end of the period alluded to by Keynes.

The peseta was the Spanish currency for more than a century and, during this time, it played a remarkable role in adjusting the balance of payments. This paper presents a chronology of the moments when the adjustment was crucial, which, consistent with the macro-trilemma, coincided with periods of external openness. Moreover, this paper provides empirical support to the thesis that links the exceptionality of a floating peseta during the gold standard with fiscal profligacy.

With sustained appreciation of the U.S. dollar over the past 4 years, the exchange rate has again taken on importance for agriculture. This overview paper revisits the analysis of exchange rate impacts, reviewing the relevant conceptual arguments, summarizing the evidence economists and agricultural economists have marshaled from the 1970s and the 1980s and from several more recent papers, presenting some illustrative recent empirical analysis of exchange rate effects, and briefly examining the detrimental consequences that sustained appreciation of the dollar is having on U.S. farm policy.

The effects of the U.S. dollar exchange rate versus the Mexican peso are evaluated for four traded nonfarm-produced inputs (fertilizer, chemicals, farm machinery, and feed) in the U.S. Unit root tests suggest that the exchange rate and the four input price ratios support the presence of unit roots with a trend model but the presence unit roots can be rejected in the first difference model. This result is consistent with a fixed price/flex price conceptual framework, with industrial prices more likely to be unresponsive to the exchange rate than farm commodity prices.

This paper considers which currency option would be best for an independent Scotland. We examine three currency options: being part of a sterling currency zone, adopting the euro, or having an independent currency. No currency option is the best when considered against all criteria. Therefore, making the decision requires deciding which criteria are most important. Recent events around the world, particularly in Europe, show that it is essential to consider how an independent Scotland would seek to adjust to adverse economic circumstances. In economists' terms, it is important to think through the ‘off-equilibrium’ adjustment paths of each of the currency options. The amount of public debt, and so the capacity for a fiscal response, is a critical determinant of these paths and therefore of the optimal currency choice. Since commitment to a currency union by an independent country can only be conditional, an independent Scotland might find it optimal to abandon the currency union in the future if the financial stability advantages to having its own currency begin to outweigh any disadvantages due to trade and transactions costs.

This paper addresses the role of markup variations in the transmission process of cross-sectoral productivity differential shocks and government spending shocks to the relative price of nontradables. The Balassa-Samuelson model based on frictionless goods markets predicts that a rise in the sectoral productivity ratio by 1% raises the relative price by 1% while government spending changes leave the relative price unaffected. Using panel cointegration and unit root tests applied to a panel of fifteen OECD economies, our empirical evidence does not support these implications. We find that a rise in relative productivity by 1% raises the relative price of nontradables by only 0.70% and that an increase in government spending by 1% of GDP drives up the relative price by around 1%. This paper shows that these items of evidence can be successfully explained by a two-sector open economy model in which variations in the composition of demand for nontradables give rise to endogenous changes in the markups.

We examine the international propagation of the financial crisis of 2008, and compare it with that of the crisis of 1931. Both crises featured a flight to liquidity and safety. We argue that the collateral squeeze in the United States, which became intense after the failure of Lehman Brothers, was an important propagator in 2008; in 1931 the acceptances granted by London banks to central European borrowers propagated the crisis to the UK. In both crises, central banks' reserve management actions contributed to the liquidity crisis. And in both crises, the behaviour of creditors towards debtors, and the valuation of assets by creditors, were very important. However, there was a key difference between the two crises in the range and nature of assets that were regarded as liquid and safe: central banks in 2008, with no gold standard constraint, could liquefy illiquid assets on a much greater scale.

Korea has been a forerunner in incorporating macroprudential policies to mitigate the vulnerabilities from currency crises that can turn into a more generalised liquidity crisis. This paper examines longer-term design issues for a more resilient and stable financial system that could be expected to complement the existing macroprudential measures in achieving a more stable financial system. In particular, the paper examines the rationale and mechanics of a new public financial institution, provisionally called the Exchange Stabilisation and Guarantee Corporation (ESGC) whose main role is to buy dollar forward positions from Korean exporting companies who wish to hedge the currency exposure from long-term export orders. The ESGC is intended to mitigate the risks arising from the reliance on the role of the banking sector in providing currency hedging services to exporters. Rapid growth of short-term foreign currency denominated debt has been the result of banks receiving forward dollar sales by exporters, and then hedging the long dollar position by borrowing short in dollars. A public institution that can buy dollars forward, but which is designed so that there is no need to hedge by taking short dollar debt, can mitigate the rapid increase in short-term dollar debt in booms.

Estimation and simulation of sustainable real exchange rates in a sample of EU member countries find vulnerabilities connected to the adoption of the euro if the rate vis-à-vis the euro were to be fixed with weak fundamentals and inappropriate policies. Sample countries have benefited from dramatic improvements in their external positions, in part driven by inflows of foreign direct investment. As a result, exchange rate misalignments have narrowed in most countries and, looking ahead, are expected to narrow further. These results are conditional, however, on optimistic projections with respect to world import demand and foreign direct investment inflows.

In this paper we re-examine whether purchasing power parity holds in the long run in China from a two-steps procedure correcting outliers and testing unit roots. Thus, the efficient unit root tests developed by Elliott, Rothenberg and Stock (1996) and Ng and Perron (2001) are applied on the Renminbi bilateral (to the US dollar) real exchange rate, corrected from outliers, over the period 1970 to 2006 (in monthly frequency). We underlined the effects of large, but infrequent shocks due to changes of Chinese exchange policy undertaken since the China’s foreign exchange reform on the real exchange rate, in particular several devaluations between 1984-1994. We also show that there is no tendency to the purchasing power parity in China to hold in the long run during this period.

The aim of this paper is to evaluate to what extent more transparency can reduce the occurrence of speculative attacks. It proposes a survey of the literature about the pros and cons of transparency on the exchange rate market, which is one of the main pillars of the new international financial architecture. The effects of transparency are shown to be ambiguous both from a theoretical and empirical point of views. However, the imperfect connection resulting from the confrontation between theory and empirics suggests that some new insights are necessary in order to better catch stylised facts on the one hand and to better evaluate the theory on the other, as has been done in recent literature. This leads to new proposals for economic and informational policies.

In this paper we apply three different statistical procedures to the peseta/dollar exchange rate with the aim of discovering the true foreign exchange regime followed by the monetary authorities during the 1965–1998 period. The study's perspective emphasizes the divergence between de jure and defacto exchange regimes. The results seem to imply that the peseta, as well as other currencies, did not exhibit the floating regime that de jure had in relation to the US dollar in the last three decades of its existence. On the contrary, the peseta/dollar exchange rate moved within rather narrow fluctuation bands during those years.

This article explores the behavior of exchange rates in Spain during the 18th century. We analyze the exchange rates quoted in London on three Spanish cities between 1699 and 1826. After a brief review of how the Spanish monetary system worked and how exchange rates were determined, we assess to which extent the exchange rate responded to market fundamentals by testing two theoretical models of exchange rate determination. The results suggest that purchasing power parity held during the 18th century, with the exchange rate tracking quite closely the behavior of inflation differentials. Deviations from PPP appeared at the end of the century, due mostly to changes in the real exchange rate caused by the bilateral trade between Spain and Great Britain and, maybe, due to productivity differentials.

Dans cette étude, il s’agit de caractériser le taux de change réel d’équilibre de long terme d’une petite économie ouverte à deux secteurs de production, dans laquelle les agents ont une durée de vie finie au sens de Blanchard (1985). Ce cadre théorique permet de relâcher l’hypothèse d’égalité entre le taux de préférence pour le présent et le taux d’intérêt mondial. Par ce biais, l’écart entre le taux d’intérêt et le taux de préférence pour le présent détermine la position financière nette de l’économie domestique vis-à-vis du reste du monde. Celle-ci conditionne en retour la réaction des principales variables économiques à une modification exogène du taux d’intérêt. L’impact d’une hausse du taux d’intérêt sur le taux de change réel d’équilibre dépend de la valeur des élasticités de la production par rapport au capital dans les deux secteurs, tandis que la consommation et le stock de capital se comportent différemment selon la position financière du pays.

Nous examinons l'effet de la situation économique de l'Allemagne après la réunification sur les taux d'intérêt en Europe et sur les taux de change vis-à-vis du dollar. Nous nous demandons en particulier ce qu'est la perspective la plus probable pour les parités, l'écart de taux d'intérêt entre la franc et le mark et les dettes exterieures. Nous ana-lysons la possibilité pour la France de mener une politique monétaire indépendante sans quitter le S.M.E. Cette possibilité dépend largement, nous le verrons, de la nature du risque de change entre franc, mark et dollar.
