Currency interdependence and dollarization

This paper constructs a search model of currency interdependence, and uses it to examine how in dollarized economies the foreign currency reacts to various shocks to the domestic currency. Currency interdependence is generated by allowing sellers to take into account their outside option of trading with the domestic currency while bargaining with buyers holding the foreign currency. The shocks consist in movements in the domestic interest rate, domestic inflation and the domestic currency’s market power. We show that if the purchasing power of the domestic currency is low, any shock that increases its value, such as a higher domestic interest rate, translates into a depreciation of the foreign currency. However, the result is opposite when the purchasing power of the domestic currency is high. We show that when money is indivisible these shocks can drive in or out the foreign currency. When money is divisible, this currency substitution effect is more limited. We use our results to discuss the opportunity of various de-dollarization policies and show that some can be counterproductive.     

On the benefits of fiscal policy coordination in a currency union: a note

It is quite often claimed by politicians that a common currency makes it beneficial to be also endowed with a common fiscal policy. However, if fiscal policy can reasonably be considered to be a source of shocks, national fiscal policies which are steered independently from each other are generally preferable because they allow the possibility to diversify macroeconomic risks. Abstracting from automatic stabilizers, this view is valid independent on whether the ECB targets money growth or interest rates.

Evaluating currency crises: A Bayesian Markov switching approach

In this paper we examine the nature of a currency crisis. We do so by employing an out-of-sample forecasting exercise to analyse the Mexican crisis in 1994. Forecast evaluation was based on modern econometric techniques concerning the shape of forecaster’s loss function. We also extend the empirical framework suggested by Jeanne and Masson [Jeanne, O., Masson, P., 2000. Currency crises and Markov-switching regimes. Journal of International Economics 50, 327–350] to test for the hypothesis that the currency crisis was driven by sunspots. To this end we contribute to the existing literature by comparing Markov regime switching model with a time-varying transition probabilities with two alternative models. The first is a Markov regime switching model with constant transition probabilities. The second is a linear benchmark model. Empirical results show that the proxy for the probability of devaluation is an important factor explaining the nature of currency crisis. More concretely, when the expectation market pressure was used as a proxy of probability of devaluation, forecast evaluation supports the view that currency crisis was driven by market expectation unrelated to fundamentals. Alternatively, when interest rate differential is used as a proxy for probability of devaluation, currency crisis was due to predictable deterioration of fundamentals.     

Evaluating currency crises: the case of the European monetary system

In this paper we examine the nature of currency crises. We ascertain whether the currency crises of the European Monetary System (EMS) were based either on fundamentals, or on self-fulfilling market expectations driven by extrinsic uncertainty. In particular, we extend previous work of Jeanne and Masson (J Int Econ 50:327–350, 2000) regarding the evaluation of currency crisis. We contribute to the existing literature proposing the use of Markov regime-switching with time-varying transition probability model. Our empirical results suggest that the currency crises of the EMS were not due only to market expectations driven by external uncertainty, or ‘sunspots’, but also to fundamental variables that help to explain the behavior of market expectations. We would like to thank Joseph Byrne, James Mitchell, Martin Weale and two anonymous referees for very useful comments and suggestions.     

Choice of currency basket weights and its implications on trade balance

This paper seeks to find an optimal choice of currency basket weights for emerging economies that peg their currencies to a currency basket, and to examine the long-run relationship between the real exchange rates of a group of trading partners. A general equilibrium model is set up to establish an optimal set of currency basket weights, coupled with the choice of fiscal policy, to simultaneously stabilize trade balance and aggregate price level of an economy. This optimal set of weights is a weighted average of two sets of weights; each targets at one policy goal (stabilizing either balance of trade or aggregate price level) at a time. Empirical studies including vector autoregression (VAR) analysis and cointegration analysis on the long-run relationship between the Thai baht and the real exchange rates of its major trading partners are presented.     

Currency restrictions,government transaction policies and currency exchange

Summary. We study how currency restrictions and government transaction policies affect the values of fiat currencies in a two country, divisible good, search model. We show that these policies can generate equilibria where both currencies circulate as medium of exchange and where currency exchange occurs between citizens of different countries. Restrictions on the internal use of foreign currency can cause the domestic currency to be relatively more valuable to domestic agents while taxes on domestic currency create an incentive for home agents to hold foreign currency. We demonstrate that some policies increase prices and lower welfare while others do the reverse. Received: September 5, 2001; revised version: March 1, 2002     

Central Bank Digital Currency: optimization of the currency system and its issuance design

Central Bank Digital Currency (CBDC) contributes to optimizing payment functions of fiat money, reducing reliance on payment services provided by the private sector, alleviating regulatory burdens and pressure on the central bank, and strengthening the authority of fiat money. Moreover, issuance of CBDC helps to address dilemmas of modern monetary policies, including inefficiencies in policy transmission, difficulties in countercyclical control, flow of currency away from the real economy to the virtual economy and inadequate management of policy expectations. This paper proposes a CBDC issuance framework based on forward contingencies. The incorporation of time, sector, and loan rate contingencies in the activation of CBDC will realize real-time transmission of monetary policy, enable targeted supply of money and prevent the currency from circulating beyond the real economy. The economic state contingency makes it possible to exercise countercyclical control of currency. The embedment of these contingencies also enables currency to perform the function of forward guidance.     

Explaining ERM realignments: Insights from optimising models of currency crises

This paper attempts to provide empirical evidence on the determinants of the realignments throughout the European exchange rate mechanism (ERM). Motivated by the implications of optimising currency crisis models, we relate the probability of “crises” to a set of macroeconomic fundamentals. By using a conditional binominal logit model we show that regime switches are strongly influenced by movements in industrial production, foreign interest rates, competitiveness and imports as well as in foreign exchange reserves. These findings are consistent with the general propositions of recent currency crises models.     

Regional Currencies Versus Dollarization: Options for Asia and the Americas

This paper undertakes an empirical assessment of Dollarization versus regional currency union as options for the economies of East Asia, South America and Central America. We use summary indicators of bilateral integration to examine the determinants of real exchange rate volatility within each region and between each region and the United States. While Europe is characterized by a high degree of regional integration, there is evidence of increasing integration in East Asia and persistently low integration in the Americas, especially as compared to the levels of bilateral integration vis-à-vis the United States. Our estimates confirm the patterns of regional integration above and reveal substantial regional differences as to the determinants of real exchange rate volatility.     

Choice of exchange rate regime and currency zones

We investigate the choice of exchange rate regimes in different currency zones (the US dollar, Euro and the CFA zones), and geographic regions (Latin America and Caribbean, East Asia and Pacific, Europe, core Europe, and the CFA countries). We control for country and regional heterogeneity, time dummies, endogeneity and perform various robustness checks. Results from regional analysis substantially differ from the aggregate analysis despite controlling for random effects. Even at the regional level controlling for currency zones affects our findings. Regional results are generally robust to regime measurement, and sample changes (number of observations).     

Political booms and currency crises

This paper shows evidence that political booms, defined as the rise in governments’ popularity, are associated with a higher likelihood of currency crises. The reasoning behind this finding is that prudent economic policies to address underlying weaknesses in the economy may be political costly for incumbent governments in the short-term. Hence, popularity-concerned governments may not have enough incentives to take such corrective actions in a timely manner. This approach, in turn, can deteriorate economic fundamentals and increase related risks in the economy which can eventually lead to crises. This paper sheds light on this phenomenon in the case of currency crises, suggesting that currency crises can be viewed as “political booms gone bust” events. Moreover, it finds that higher international reserves, higher exports, and a higher degree of financial openness alleviate the effect of political booms on currency crises.     

Psychological costs of currency transition: evidence from the euro adoption

This paper assesses the perceived individual psychological costs of adhering to the Euro. We use the difference-in-differences approach (DD), comparing individual levels of satisfaction with the economy in Slovakia immediately before and after the introduction of the Euro, with similar individuals in neighboring Czech Republic, which did not adopt the Euro. Both countries were economically and politically integrated for decades, and display similar macroeconomic behavior before and after the currency change in Slovakia. What we assess is not the actual, economic, costs stemming from the Euro adoption, but the change in utility as perceived by the individuals. There is evidence of substantial psychological costs associated with currency transition, especially for the old, the unemployed, the poorly educated and households with children. Our results are robust to the use of alternative control groups and to estimation procedures using the DD matching approach. The significant perceived costs uncovered in this paper suggest policy-makers should not ignore them when considering a sweeping economic change such as the adoption of a new currency.     

An analysis of East Asian currency area: Bayesian dynamic factor model approach

There has recently been an increasing interest in the establishment of a common currency area in East Asia in the aftermath of the East Asian financial crisis. In this article I examine the desirability and feasibility of forming a currency area in the region by checking the symmetry of shocks as an important criterion of the theory of Optimum Currency Area. I employ a dynamic factor model to decompose aggregate output into world, regional and country‐specific components and estimate the model using a Gibbs sampling simulation. Persistent properties of those components are examined and variance decomposition analysis is performed to investigate the role of each component in output variance. The European Monetary Union, with the successful launch of the euro, is the natural benchmark for comparison. Based on variance analysis, it is found that East Asian countries, on average, are less plausible candidates for a currency area than European counterparts. However, a subgroup of countries in East Asia is as qualified as those in Europe. Given the ongoing integration in East Asia, it is not premature to prepare for such a currency area in this region.     

Fiscal sustainability and dollarization: the case of Ecuador

This article tries to disentangle the dynamic relationships between fiscal variables and economic activity in a small emerging economy characterized by full dollarization, namely, Ecuador. We find that fiscal policy in Ecuador seems to be sustainable, explained by its policy of debt payment through oil revenues, rather than by a fiscal discipline that dollarization is supposed to encourage. The non-oil tax revenues variable is a purely adjusting variable. This result suggests that in a dollarized country that cannot benefit from the ‘seignorage’ revenues, the reliance on volatile oil revenues and on smoothing tax revenues leaves the economy’s fiscal sustainability vulnerable.     

Trend shifts in the forward premium and the predictability of excess returns in currency markets

This article provides evidence that the forward premium involves structural changes in the trend function, which might affect the predictability of currency excess returns to be dependent on the choice of the sample period. Accounting for the shifts in trend for the forward premium reveals that currency excess returns for the Canadian dollar, Swiss franc, euro and pound against the US dollar are significantly predictable irrespective of the sample period selected. Another advantage of detrending the forward premium is that we can obtain more consistent slope coefficient estimates in the predictive regression, which enables us to make more consistent, dependable inferences about the excess return predictability.     

Cobden's stance on the currency and the political forces behind the approval of the Bank Charter Act of 1844

Contemporary scholars consider the banking legislation of the first half of the nineteenth century, to have inhibited the development of British industry, However, some doubts about this conception should have arisen due to Richard Cobden's stance on the currency question in general and on the Bank Charter Act of 1844 in particular. Cobden, who is usually viewed as a representative of industrial interests, was expected to oppose the Bank Act. However, he did not.

This paper attempts to show how can Cobden's views regarding monetary policy be reconciled with his stand as one of the most prominent leaders of industry at the time.     

Data frequency and exchange rate pass-through: Evidence from India's exports

This paper studies the pricing behavior of Indian exporters using both annual and monthly data in order to uncover the role of data frequency in determining variation in the degree of short and long-run exchange rate pass-through (ERPT). Export price data during the post-1991 economic reforms period is disaggregated at the two-digit industry level and using a novel methodology in the ERPT literature (cointegration for heterogeneous panels) cross-industry differences in adjustment are identified. We observe that there is clear evidence of incomplete ERPT to prices in India's export markets, after having controlled for the level of exchange rate volatility and domestic inflation as an indicator of variations in marginal cost. The empirical results indicate that monthly data reflect more incomplete ERPT to destination market prices, relative to annual data, in which all the short run rigidities are more likely to have been adjusted. Thus studies that use higher frequency data are more likely to find incomplete ERPT in the short-run, even in the context of an emerging market economy. In the long-run, incomplete ERPT subsists in a few industries for both data frequencies.     

Is There a Link Between Exchange Rate Pass-Through and the Monetary Regime: Evidence from Sub-Saharan Africa and Latin America

This paper investigates the relationship between the monetary regime: pegged, currency board, dollarization, and the exchange rate pass-through for a sample consisting of 15 Sub-Saharan Africa countries and 12 Latin American countries. The research findings about pass-through rates will shed light on the feasibility of a monetary union for Sub-Saharan Africa. The inclusion of the latter country group was deemed desirable to explore pass-through behavior in several monetary regime options not often used in Sub-Saharan Africa.

Long-term appointment of central bankers: costs and benefits

Why do independent central bank boards have a reputation for more moderate policy than do elected governments, even if the board's members have been appointed by the current or former government? This paper gives an explanation for the case of a political world with ‘zeitgeist shocks’ on the electorate's preferences. If the median position of preferences inside the board determines the monetary policy, a trade-off concerning member term length arises: a longer term entails more moderation, while enhancing the likelihood of detachment from contact to the electorate's current preferences.
