THE THREE FACES OF THE INTERNATIONAL COMPARISON PROJECT

Purchasing power parities (PPPs), this article confirms, arethe correct converters for translating GDP and its componentsfrom own-currencies to dollars (the usual numeraire); the alternativemeasure, exchange rates, obscures the relationship between thequantity aggregates of different countries. Drawing on the reportsof the United Nations International Comparison Project (ICP),the article contends that exchange rates systematically understatethe purchasing power of the currencies of low-income countriesand thus exaggerate the dispersion of national per capita incomes.Where full-scale (benchmark) PPP estimates are not available,estimates based on shortcut methods better approximate whatthe benchmark estimates would be than do the exchange rate conversions.The ICP results also illuminate price and exchange rate relationshipsamong countries by providing a measure of the difference inthe levels of prices in different countries. ICP price comparisonsfor components of GDP make possible the analysis of comparativeprice and quantity structures of different countries and providethe raw materials for many types of analytical studies.      

THE ECONOMICS OF NATURAL RESOURCE EXTRACTION: A PRIMER FOR DEVELOPMENT ECONOMISTS

As developing countries become major consumers of the globalsupply of commercial energy, it is essential to understand thedeterminants of future energy prices. At the same time, manydeveloping countries are relying on exports of their own naturalresources—tropical hardwoods, oil, tin, gold, and otherminerals—to generate badly needed foreign exchange. Governmentpolicies influence how much of a resource is extracted todayand how much is saved for the future. Flawed policies needlesslywaste precious national wealth.      

MACROECONOMIC ADJUSTMENT TO CAPITAL INFLOWS: LESSONS FROM RECENT LATIN AMERICAN AND EAST ASIAN EXPERIENCE

Capital inflows to some developing countries have increasedsharply in recent years. Impelled by better economic prospectsin those countries, lower international interest rates, anda slowdown of economic activity in the capital-exporting countries,the inflows have furnished financing much needed to increasethe use of existing capacity and to stimulate investment. Butcapital inflows can bring with them their own problems. Typicalmacroeconomic repercussions have been appreciation of the realexchange rate, expansion of nontradables at the expense of tradables,larger trade deficits, and, in regimes with a fixed exchangerate, higher inflation and an accumulation of foreign reserves. Should government intervene to limit some of these side effects—andif so, how? The question is especially pressing in the wakeof the Mexican crisis of December 1994. This article looks foranswers in the experience of four Latin American and five EastAsian countries between 1986 and 1993, examining the effectsof the capital inflows on the economy and comparing the differentways in which these countries responded to the problem of "toomuch" capital.      

Dual foreign currency markets and the role of expectations: Evidence from the Pacific Basin countries

This paper analyzes the role of expectations about the government policy in the official foreign currency market in determining the black market premium. We use data for the recent float from six emerging markets of the Pacific Basin where active black markets for foreign currency exist, namely, Indonesia, Korea, Malaysia, the Philippines, Singapore and Thailand. To test the impact of anticipated and unanticipated shocks to the official exchange rate on the black market premium, we employ the two-step procedure of Hoffman et al. [Hoffman, D.L., Low, S.A., Schlagenhauf, D.E., 1984. Tests of rationality, neutrality and market efficiency: a Monte Carlo analysis of alternative test statistics. J. Monet. Econ. 14, 339–363] which provides corrected F-statistics and allows us to draw valid inference in the presence of generated regressors. The main finding of our analysis is that anticipated and unanticipated shocks to the official exchange rate have an impact on the black market premium in all six Pacific Basin countries. These results suggest that portfolio balance models provide the suitable theoretical framework for analyzing the behaviour of the black market premium in the markets for foreign currency in the Pacific Basin countries. Furthermore, this implies that economic agents in these countries are sensitive to expected returns in foreign exchange.     

Do long-term swings in the dollar affect estimates of the risk premia?

Foreign exchange returns exhibit behavior difficult to reconcilewith standard theoretical models. This article asks whetherthe recent findings of long swings in exchange rates betweenappreciating and depreciating periods affect estimates of theforeign exchange risk premium. We demonstrate how the 'pesoproblem' introduced by expected shifts in exchange rate regimescan affect inferences about the risk premium in at least twoways: (1) it can make the foreign exchange risk premium appearto contain a permanent disturbance when it does not; and (2)it can induce bias in the foreign exchange return regressionssuch as in Fama (1984).     

Foreign Bank Entry: Experience, Implications for Developing Economies, and Agenda for Further Research

In recent years foreign banks have expanded their presence significantlyin several developing economies. In Argentina and Chile in LatinAmerica and in the Czech Republic, Hungary, and Poland in EasternEurope, foreign-controlled banks now hold more than half oftotal banking assets. In other regions the trend is similar,though foreign bank entry has been slower. Despite the growingnumber of countries embracing foreign bank entry, importantquestions are still being debated: What draws foreign banksto a country? Which banks expand abroad? What do foreign banksdo once they arrive? How do foreign banks' mode of entry andorganizational form affect their behavior? This article summarizescurrent knowledge on these issues. Because the existing literaturefocuses heavily on developed economies, it also puts forth anagenda for further study of the causes and effects of foreignbank entry in developing economies.      

Tests of the hypothesis of the existence of risk premium in the foreign exchange market

This paper tests for a risk premium in the foreign exchange market. The null hypothesis of the test is the random walk hypothesis in the foreign exchange market. The alternative hypothesis is that biases of current spot rates (or forward rates) from future spot rates are systematically related to a set of economic variables on which a risk premium may depend. This paper provides firm evidence for a risk premium in the foreign exchange market. The risk premium explains 10–20% of the total variance in future spot rates when the US dollar/mark quarterly rates are used. The magnitudes are smaller (less than 10%) for monthly rates.     

Modeling Foreign Exchange Risk Premium in Armenia

This paper applies stochastic discount factor methodology to modeling the foreign exchange risk premium in Armenia. We use weekly data on foreign and domestic currency deposits, which coexist in the Armenian banking system. This coexistence implies elimination of the cross-country risks and transaction costs, leaving the pure foreign exchange risk. It is shown that there exists a systematic time-varying risk premium that increases with maturity. Using two-currency affine term structure and generalized autoregressive conditional heteroskedasticity (GARCH)-in-mean models, we find that the central bank's foreign exchange market interventions and ratio-of-deposit volumes significantly affect public expectations about foreign exchange fluctuations. We also find that the foreign exchange risk premium accounts for the largest part of the interest differential. When accounting for economic and institutional differences, our results can be extended to other countries.     

OPTIONS FOR DISMANTLING TRADE RESTRICTIONS IN DEVELOPING COUNTRIES

Although many countries have adopted freer trade regimes orare in the process of reforming quantitative restrictions, suchreforms are not without shortterm costs. Sudden removal of quantitativerestrictions can release a surge of demand for imports thatcan deplete foreign exchange reserves and force rapid adjustmentby domestic industries. Five methods to more gradually liberalizequantitative restrictions are discussed: raising quota ceilingsuntil they are non-binding; eliminating quotas product by product;converting quotas to equivalent tariffs and then reducing them;auctioning quota licenses; and converting quotas to tariff quotas,and then liberalizing these. The various instruments are evaluatedaccording to their implications for the adjustment period, forgovernment revenue, for the balance of payments, and for theextent to which they are likely to produce political disruptions.      

The term structure of the forward premium

Most studies of the efficiency of the foreign exchange market focus on a single maturity — usually a one month forward exchange rate. However, one observes that forward contracts of many maturities are simultaneously traded in the foreign exchange market. The hypothesis that the foreign exchange market uses all available information has implications for the joint behavior of forward exchange rates of various maturities. This paper proposes an equilibrium theory of the term structure of the forward premium. The model is tested using data on the German and Canadian exchange rates; the results indicate that the data are consistent with the theory for Germany and inconsistent with the theory for Canada.     

ISSUES IN MEDIUM-TERM MACROECONOMIC ADJUSTMENT

Four years after the onset of the world debt crisis, the issueis how to restore growth. The answer is structural adjustment,both macro and micro. At the macro level, adjustments have tobe made to the structure of aggregate demand and supply to restoregrowth while generating the needed trade surpluses. This meansprimarily real exchange rates that are maintained at appropriatelevels and an emphasis on investment. At the micro level, itis argued that most developing countries need to liberalizetrade, allow the price system to operate, develop financialsystems, reform taxes, and improve the efficiency of publicenterprises, perhaps by selling them. The article discussesthe nature of these two types of reforms and the policy andresearch issues relevant to World Bank analysis of growth programs.      

Implied Foreign Exchange Risk Premia

This paper uses implied volatilities from foreign exchange option prices and the results of no‐arbitrage theory to estimate foreign exchange risk premia. In particular, under the assumption of no‐arbitrage, the foreign exchange risk premium is driven by the difference between investors’ market prices of risk in the two currencies. In an international economy with three currencies, sterling, US dollar and Deutschemark, we can use the information on implied volatilities of the three cross rates to derive estimates of implied or ex ante market prices of risk and of foreign exchange risk premia. The foreign exchange risk premia estimates are then compared to survey‐based risk premia.     

EXCHANGE RATE MISALIGNMENT IN DEVELOPING COUNTRIES

This article analyzes the theory of equilibrium real exchangerates and defines misalignment as a deviation of the real exchangerate (RER) from its equilibrium level. The role of macroeconomicpolicies is then analyzed under three alternative nominal exchangerate regimes: predetermined nominal exchange rates, floatingnominal rates, and dual or black market nominal exchange rates.This discussion points out how inconsistent macroeconomic policiesoften lead to real exchange rate misalignment. Corrective measures,including nominal devaluations and several alternative approaches,are then evaluated.      

A SIMPLER CONSUMPTION-BASED ALTERNATIVE TO THE INCOME TAX FOR SOCIALIST ECONOMIES IN TRANSITION

The tax systems of socialist economies in transition will distortresource allocation, create inequities, and cause administrativeheadaches if not reformed. These countries have weak tax administrations,lack experience with mass taxes based on voluntary compliance,and need to encourage domestic saving and foreign investment.This article suggests an alternative to the conventional incometax that is more suited to these conditions. Attempting to tax real economic income raises complicated timingissues (when to recognize income and allow deductions) and mayrequire complex adjustments for inflation. The simplified alternativetax (SAT) avoids these complications and provides a generalincentive for saving and investment less subject to abuse ordistortions than tax holidays and other tax gimmicks in voguein countries emerging from socialism. The key elements of the SAT are separate taxes on income fromlabor and capital, immediate deduction for all business expenditures,no deduction for interest, and no taxation of interest or dividends.(Interest could be treated as under an income tax, at some cost.)Although the marginal effective tax rate is zero, the governmentshares in extraordinary returns to investment. The article discussespotential problems (including distributional implications, taxlosses, and foreign tax credits) as well as advantages of theSAT.      

Nonlinear dynamics in foreign exchange rates

This paper investigates whether the behavior of real and nominal foreign exchange rates as well as interest rates are governed by nonlinear dynamics; it also explores whether observed deviations from parity conditions exhibit nonlinear dependence. Standard statistical tests for randomness, such as autocorrelation tests, have low power against a large class of deterministic, nonlinear processes. Discerning nonrandomness of innovations in exchange rates is important for a variety of reasons. For example, many models of international asset pricing assume exchange rates to follow a random walk. Furthermore, nonlinear patterns in deviations from various exchange rate parities have implications for the existence of a time-varying foreign exchange risk premium. With the use of the BDS statistic and a correlation dimension analysis, this paper's primary findings are that (1) foreign exchange markets have become increasingly complex and therefore less amenable to forecasting over time; (2) although forward exchange risk premia are statistically significant and display a deterministic structure, this structure is complex and therefore not easily discernible; and (3) innovations in real exchange rates are consistent with a Purchasing Power Parity equilibrium.     

COMMODITY EXPORT BOOMS IN DEVELOPING COUNTRIES

This article surveys the experiences of commodity-exportingcountries faced with resource discoveries and widely fluctuatingworld prices. Favorable developments of the commodity exportmarket often prove to be a mixed blessing, as poor boom managementleads to major internal and external economic imbalances. Manydeveloping countries overconsume during boom periods. More oftenthan not, the unsustainable increases in spending are initiatedby the public sector. When the boom ends, tardiness in decreasinggovernment spending and in increasing revenues from nonboomingsectors creates fiscal deficits and monetary control problems. In the 1970s many booming economies allowed regulated pricestructures, and particularly exchange rates, to deviate substantiallyfrom free market levels, discouraging efficient resource allocationand greatly compounding the problems of adjustment to subsequentdrops in export prices. Countries that managed booms well weretypically those that (a) did not allow fiscal variables, exchangerates, agricultural producer prices, and wages to get badlyout of line, (b) avoided indulging in wasteful and inefficientinvestment or investment that involved burdensome recurrentcosts, (c) limited increases in government spending to levelsconsistent with long–term trends in revenue collection,and (d) maintained prudent external borrowing and foreign exchangereserve policies.      

PRIVATE INVESTMENT AND MACROECONOMIC ADJUSTMENT:A Survey

This article reviews theories of investment behavior and examinesempirical studies of investment in developing countries. Theemphasis is on understanding the interactions among macroeconomicpolicies, structural adjustment, and private investment. Thearticle deals with the effect of exchange rate policy on investment,the relationship between public and private investment, theimportance of market imperfections and financial constraintson capital formation, and the effect of economic instabilityon irreversible investment decisions.      

USING AUCTIONS TO ALLOCATE AND PRICE LONG-TERM CREDIT

Most long-term credit in developing countries is allocated throughnegotiated agreements between government institutions and financialintermediaries or final borrowers, and often at administeredrates. Yet many developing countries have no long-term creditmarket whose interest rates can be used as benchmarks for theseloans. If credit is priced improperly, it will be allocatedinefficiently and the development of capital markets may bestunted. In light of the generally disappointing experiencewith conventional methods of allocating development credit,some countries have introduced credit auctions as an alternative.Among the advantages are greater transparency and fairness,lower transaction costs, and increased competition and efficiency.Among the disadvantages are a greater vulnerability to collusion,which can lead to lower interest rates and revenue, and a tendencyto attract the least desirable participants (adverse selection)and to lend for riskier projects (moral hazard), which can leadto lower repayment rates and a higher probability of default.All these factors can lead to inefficiency in the allocationof funds. This article suggests ways to lessen these negativeeffects and presents various elements of auction design thataffect the efficiency of credit auctions and their suitabilityto specific circumstances. When properly designed, auctionscan be used in a variety of environments to allocate developmentcredit more efficiently than current methods do.      

Foreign exchange and lost opportunity in the US Department of Defense

This paper examines US Department of Defense (DoD) foreign exchange rate exposure in light of the government’s prohibition against foreign currency hedging. Using data from the United States Air Force and Monte Carlo simulation, we evaluate whether the use of forward foreign exchange contracts or currency options might reduce the financial impact of currency fluctuation. The results strongly indicate that these alternatives outperform the current method for dealing with foreign currency exposure in the DoD. Using forward contracts, expected cost reductions are on the order of 3.5% of current outlays. For options, expected cost reductions increase to 6.4% thereby defining an upper bound of 2.9% on acceptable option premium levels.
