The single most important aspect of an exchange rate regime is the degree
of flexibility. The matter is of course more complicated than a simple choice
between fixed exchange rate and floating. One can array exchange rate regimes
along a continuum, from most flexible to least, and grouped in three major
categories:
- Floating corner
- Free float
- Managed float
- Intermediate regimes
- Target zone or band
- Basket peg
- Crawling peg
- Adjustable peg
- Institutionally fixed corner
- Currency board
- Dollarization
- Monetary Union
This chapter reviews the state of research concerning how a country should
choose where to locate along this continuum of exchange rate regimes.
The ‘‘corners hypothesis’’ - that countries are, or should be, moving away
from the intermediate regimes, in favor of either the hard peg corner or the
floating corner - was proposed by Eichengreen (1994) and rapidly became the
new conventional wisdom with the emerging market crises of the late 1990s.
But it never had a good theoretical foundation. The feeling that an intermediate
degree of exchange rate flexibility is inconsistent with perfect capital mobility
is a misinterpretation of the principle of the impossible trinity. To take a clear
example, Krugman (1991) shows theoretically that a target zone is entirely
compatible with uncovered interest parity. The corners hypothesis began to lose
popularity after the failure of Argentina’s quasi currency board in 2001. Many
countries continue to follow intermediate regimes and do not seem any the worse
for it.
Attempts to address the optimal degree of exchange rate flexibility within
a single theoretical model are seldom very convincing. Too many factors are
involved. Better instead to enumerate the arguments for and against exchange
rate flexibility and then attempt to weigh them up. This chapter considers five advantages of fixed exchange rates, followed by five advantages for exchange rate flexibility. We then turn to analysis of how to weigh the pros and cons to choose a regime. The answer depends on characteristics of the individual country in question.
Download ChapterCountries with oil, mineral or other natural resource wealth, on average, have failed to show better economic performance than those without, often because of undesirable side effects. This is the phenomenon known as the Natural Resource Curse. This paper reviews the literature, classified according to six channels of causation that have been proposed. The possible channels are: (i) long-term trends in world prices, (ii) price volatility, (iii) permanent crowding out of manufacturing, (iv) autocratic/oligarchic institutions, (v) anarchic institutions, and (vi) cyclical Dutch Disease. With the exception of the first channel--the long-term trend in commodity prices does not appear to be downward--each of the other channels is an important part of the phenomenon. Skeptics have questioned the Natural Resource Curse, pointing to examples of commodity-exporting countries that have done well and arguing that resource exports and booms are not exogenous. The relevant policy question for a country with natural resources is how to make the best of them.
Download ChapterA new climate change treaty must address three current gaps: the absence of emissions targets extending far into the future; the absence of participation by the United States, China, and other developing countries; and the absence of reasons to expect compliance. Moreover, to be politically acceptable, a post-Kyoto treaty must recognize certain constraints regarding country-by-country economic costs. This article presents a framework for assigning quantitative emissions allocations across countries, one budget period at a time, through a two-stage plan: (a) China and other developing countries accept targets at business-as-usual (BAU) levels in the coming budget period, and, during the same period, the United States agrees to cuts below BAU; (b) all countries are asked to make further cuts in the future in accordance with a formula that includes a Progressive Reductions Factor, a Latecomer Catch-up Factor, and a Gradual Equalization Factor. An earlier proposal (Frankel 2009) for specific parameter values in the formulas achieved the environmental goal that carbon dioxide (CO2) concentrations plateau at 500 ppm by 2100. It met our political constraints by keeping every country’s economic cost below thresholds of Y = 1 percent of income in Present Discounted Value, and X = 5 percent of income in the worst period. The framework proposed in this article attains a stricter concentration goal of 460 ppm CO2 but only by loosening the political constraints.
Download PaperWe investigate whether leading indicators can help explain the cross-country incidence of the 2008–09 financial crisis. Rather than looking for indicators with specific relevance to the recent crisis, the selection of variables is driven by an extensive review of more than eighty papers from the previous literature on early warning indicators. Our motivation is to address suspicions that indicators found to be useful predictors in one round of crises are typically not useful to predict the next round. The review suggests that central bank reserves and past movements in the real exchange rate were the two leading indicators that had proven the most useful in explaining crisis incidence across different countries and episodes in the past. For the 2008–09 crisis, we use six different variables to measure crisis incidence: drops in GDP and industrial production, currency depreciation, stock market performance, reserve losses, and participation in an IMF program. We find that the level of reserves in 2007 appears as a consistent and statistically significant leading indicator of who got hit by the 2008–09 crisis, in line with the conclusions of the pre-2008 literature. In addition to reserves, recent real appreciation is a statistically significant predictor of devaluation and of a measure of exchange market pressure during the current crisis. We define the period of the global financial shock as running from late 2008 to early 2009, which probably explains why we find stronger results than earlier papers such as Obstfeld et al. (2009, 2010) and Rose and Spiegel (2009a,b, 2010, 2011) which use annual data.
Download PaperDeveloping countries traditionally experience pass-through of exchange rate changes that is greater and more rapid than high-income countries experience. This is true equally of the determination of prices of imported goods, prices of local competitors’ products, and the general CPI. But developing countries in the 1990s experienced a rapid downward trend in the degree of pass-through and speed of adjustment, more so than did high-income countries. As a consequence, slow and incomplete pass-through is no longer exclusively a luxury of industrial countries. Using a new data set - prices of eight narrowly defined brand commodities, observed in 76 countries - we find empirical support for some of the factors that have been hypothesized in the literature, but not for others. Significant determinants of the pass-through coefficient include per capita incomes, bilateral distance, tariffs, country size, wages, long-term inflation, and long-term exchange rate variability. Some of these factors changed during the 1990s. Part (and only part) of the downward trend in pass-through to imported goods prices, and in turn to competitors’ prices and the CPI, can be explained by changes in the monetary environment - including a fall in long-term inflation. Real wages work to reduce pass-through to competitors’ prices and the CPI, confirming the hypothesized role of distribution and retail costs in pricing to market. Rising distribution costs, due perhaps to the Balassa-Samuelson-Baumol effect, could contribute to the decline in the pass-through coefficient in some developing countries.
Download PaperThe possibility that the renminbi may soon join the ranks of international currencies has generated much excitement. This paper looks to history for help in evaluating the factors determining its prospects. The three best precedents in the twentieth century were the rise of the dollar from 1913 to 1945, the rise of the Deutsche mark from 1973 to 1990, and the rise of the yen from 1984 to 1991. The fundamental determinants of international currency status are economic size, confidence in the currency, and depth of financial markets. The new view is that, once these three factors are in place, internationalization of the currency can proceed quite rapidly. Thus some observers have recently forecast that the RMB may even challenge the dollar within a decade. But they underestimate the importance of the third criterion, the depth of financial markets. In principle, the Chinese government could decide to create that depth, which would require accepting an open capital account, diminished control over the domestic allocation of credit, and a flexible exchange rate. But although the Chinese government has been actively promoting offshore use of the currency since 2010, it has not done very much to meet these requirements. Indeed, to promote internationalization as national policy would depart from the historical precedents. In all three twentieth-century cases of internationalization, popular interest in the supposed prestige of having the country’s currency appear in the international listings was scant, and businessmen feared that the currency would strengthen and damage their export competitiveness. Probably China, likewise, is not yet fully ready to open its domestic financial markets and let the currency appreciate, so the renminbi will not be challenging the dollar for a long time.
We begin, however, by asking: What is international currency status, and why does it matter?
