Oil, Macroeconomics, and Forests: Assessing the Linkages

How does an oil boom affect the forest cover of tropical oil-exportingcountries? What macroeconomic linkages and policies are decisive?A comparison of research findings on long-run land-use changesin eight tropical developing economies reveals that the directphysical impacts of the oil industry on forests are unquestionablyless than its derived macroeconomic impact. In most cases oilwealth indirectly but significantly protects tropical forests.The core mechanism is that oil rents cause macroeconomic "Dutchdisease" decreasing the price competitiveness of agricultureand logging, strongly diminishing pressures for forest degradationand deforestation. But domestic policy responses to oil wealthare also vital determinants of the forest outcome. When governmentsuse oil wealth for urban spending sprees, this reinforces thecore effect by pulling more labor out of land-using and forest-degradingactivities. When oil revenues finance road construction or frontiercolonization, however, the core forest-protective effect canbe reversed. Repeated currency devaluation and import protectionof land-using domestic sectors also increase pressures on forests.Other international capital transfers, like bilateral credits,aid, or debt relief, can have impacts similar to those of oilwealth, either alleviating pressures on forests or aggravatingspecific forest-detrimental policies. These insights point toforest-friendly safeguards that can realistically be made inthe design of structural adjustment programs, considering theimportant tradeoffs between development and conservation objectives.      

FISCAL DEFICITS AND MACROECONOMIC PERFORMANCE IN DEVELOPING COUNTRIES

Although fiscal adjustment was urged on developing countriesduring the 1980s to lead them out of economic malaise, considerableuncertainty remains about the relations between fiscal policyand macroeconomic performance. To illustrate how financial markets,private spending, and the external sector react to fiscal policies,the behavior of holdings of money and public debt, private consumptionand investment, the trade balance, and the real exchange rateis modeled for a sample of ten developing countries. The studiesfind strong evidence that over the medium term, money financingof the deficit leads to higher inflation, while debt financingleads to higher real interest rates or increased repressionof financial markets, with the fiscal gains coming at increasinglyunfavorable terms. Consumers respond differently to conventionaltaxes, unconventional taxes (through inflation or interest andcredit controls), and debt financing, in ways that make fiscaladjustment the most effective means of increasing national saving.Private investment—but not private consumption—issensitive to the real interest rate, which rises under domesticborrowing to finance the deficit. Contrary to the popular presumption,in some countries private investment increases when public investmentdecreases. There is strong evidence that fiscal deficits spillover into external deficits, leading to appreciation of thereal exchange rate. Fiscal deficits and growth are self-reinforcing:good fiscal management preserves access to foreign lending andavoids the crowding out of private investment, while growthstabilizes the budget and improves the fiscal position. Thevirtuous circle of growth and good fiscal management is oneof the strongest arguments for a policy of low and stable fiscaldeficits.      

REFORM OF TRADE POLICY: Recent Evidence from Theory and Practice

In the 1980s many developing countries began to recognize thatrestrictive trade policies can constrain growth. To facilitatetrade and integration into the world economy, many countrieshave embarked on reform programs. This survey synthesizes theconclusions of the literature on trade policy reform with thoseof a recent study by the World Bank analyzing reforms in developingcountries, particularly those supported by adjustment lendingprograms. Its objective is to shed light on some of the questionsabout these programs to guide policymakers in the future. Thearticle reviews conditions in these countries before trade policyreforms were implemented and examines how much reform actuallytook place. It also examines the effects of the reforms on economicperformance and reviews the factors that constrained the reformprocess. The survey considers the most important issues in designingand implementing trade policy reforms and concludes that althoughpast reforms have had a positive impact, future programs shouldemphasize three elements: reducing the level of protection,maintaining macroeconomic stability, and accounting for theconflicts and complementarities with other policies.      

MACROECONOMIC ADJUSTMENT AND POVERTY IN AFRICA: AN EMERGING PICTURE

The view that macroeconomic adjustment disproportionately hurtsthe poor in Africa has become commonplace. The popular mediaand the nongovernmental aid community frequently express thisview in critiques of Bankfunded economic reform programs. Yetthe evidence on which the claim has been based is flimsy andanecdotal. The emergence of more convincing data, from detailedhousehold surveys in Africa, provides an opportunity to setthe record straight. The evidence from six African countries reviewed in this articledemonstrates that poverty was more likely to decline in thosethat improved their macroeconomic balances than in those thatdid not. The critical factor is economic growth: the economygrew more rapidly and poverty declined faster in countries thatimproved macroeconomic balances, depreciating the real effectiveexchange rate. Changes in the real exchange rate also immediatelyand favorably affected rural incomes, benefiting the poor bothdirectly and indirectly. But the findings also highlighted threecauses for policy concern. First, many African governments haveyet to display a real commitment to macroeconomic reform; second,the poorest of the poor have not benefited from recent growthin some countries; and, third, the prospects for the poor arenot rosy unless there is more investment in human capital andbetter targeting of social spending.      

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.      

Sustainability of macroeconomic policies in selected MENA countries: Post financial and debt crises

In the wake of the recent financial and debt crises, the conduct of macroeconomic policies in the emerging MENA economies has recently become critical in determining those countries future economic situation, due to the accumulation since the early 1990s of a sizable level of external debt, and the pursuit by some countries of a fixed exchange rate regime. Using time series econometric models, this study assesses the sustainability of macroeconomic policies in a selected sample of 4 MENA countries. The empirical results point to sustainable fiscal and exchange rate policies in Tunisia and Morocco, and unsustainable external debt and exchange rate policies in Egypt and Jordan. While Egypt has recently moved to a flexible exchange rate regime, if Jordan still opts for maintaining a fixed exchange rate arrangement, it will have to implement crisis-prevention measures, namely by exercising fiscal discipline, and managing properly its external debt and foreign reserves.     

Contagion: Understanding How It Spreads

Much of the current debate on reforming the international financialarchitecture is aimed at reducing the risks of contagion—bestdefined as a significant increase in cross-market linkages aftera shock to an individual country (or group of countries). Thisdefinition highlights the importance of other links throughwhich shocks are normally transmitted, including trade and finance.During times of crisis, the ways in which shocks are transmitteddo seem to differ, and these differences appear to be important.Empirical work has helped to identify the types of links andother macroeconomic conditions that can make a country vulnerableto contagion during crisis periods, although less is known aboutthe importance of microeconomic considerations and institutionalfactors in propagating shocks. Empirical research has helpedto identify those countries that are at risk of contagion aswell as some, albeit quite general, policy interventions thatcan reduce risks.      

WHEN DO HETERODOX STABILIZATION PROGRAMS WORK?: Lessons from Experience

What advantages and disadvantages does the heterodox strategyoffer to stabilization programs in countries with chronic highinflation? Heterodox stabilization programs, in our definition,are those that support orthodox policies— that is, tightfiscal policy and a fixed exchange rate—with the initial,temporary use of incomes policies— that is, price andwage controls. This evaluation, based on several heterodox programs,successful and unsuccessful, from the 1960s and 1980s in LatinAmerican countries and Israel, affords four principal lessons: * The rapid reduction in inflation at the beginning of heterodoxprograms (which usually comes about at small cost) is the easypart; the problem is to maintain price stability over time. * Incomes policies in heterodox stabilization programs are justifiedonly in countries with high chronic inflation, where persistentinflation is more pervasive and problematic. * There is a case for a bigger fiscal adjustment in heterodoxthan in orthodox programs because of the risk that a programwith price controls may be misperceived as a populist devicefor achieving price stability without adjusting. * The failure of a heterodox program is more likely to destabilizeinflation than is the failure of an orthodox program.      

Macroeconomic Stability in Developing Countries: How Much Is Enough?

Over the 1990s macroeconomic policies improved in most developingcountries, but the growth dividend from this improvement fellshort of expectations, and a policy agenda focused on stabilityturned out to be associated with a multiplicity of financialcrises. This article examines the contents and implementationof the macroeconomic reform agenda of the 1990s. It reviewsthe progress achieved through fiscal, monetary, and exchangerate policies across the developing world and the effectivenessof the changing policy framework in promoting stability andgrowth. The main lesson is that more often than not slow growthand frequent crises resulted from shortcomings in the reformagenda of the 1990s. These concern limitations in the depthand scope of the reform agenda, its lack of attention to macroeconomicvulnerabilities, and its inadequate attention to complementaryreforms outside the macroeconomic sphere.      

Tight Money in a Post-Crisis Defense of the Exchange Rate: What Have We Learned?

Critics of the tight monetary policies pursued by some of thecountries hurt by the 1997 Asian financial crisis have questionedthe presumption that tight money can help sustain the valueof a currency. The issue is actually an empirical one becausetheory does not unambiguously predict the effect of tight moneyon the exchange rate under the circumstances faced by the crisiscountries. This article reviews the empirical research and showsthat the evidence does not yet support strong statements aboutpost-crisis links between monetary policy and the exchange rate.Proposed deviations from a sustainable medium-term monetarypolicy stance should thus be viewed with skepticism.      

STABILIZATION POLICIES IN DEVELOPING COUNTRIES

The article focuses on the design of stabilization measuresto correct excessive balance of payments deficits and moderatethe rate of inflation. It distinguishes three sources of balanceof payments difficulties—excessively expansionary aggregatedemand policies; domestic supply shocks stemming, for example,from increases in real wages in excess of productivity growth;and external terms of trade shocks. It also analyzes the effectsof devaluations. The second part of the article discusses policiesaimed at reducing the rate of inflation and summarizes the theoreticalliterature on the dynamics and the transitional costs of adjustmentto lower rates of inflation in closed economies. Evidence onthe adjustment costs of disinflationary policies is reviewed,and the discussion is extended to some recent analysis of adjustmentin open economies.      

Capital controls and optimal Chinese monetary policy

China׳s external policies, including capital controls, managed exchange rates, and sterilized interventions, constrain its monetary policy options for maintaining macroeconomic stability following external shocks. We study optimal monetary policy in a dynamic stochastic general equilibrium (DSGE) model that incorporates these “Chinese characteristics”. The model highlights a monetary policy tradeoff between domestic price stability and costly sterilization. The same DSGE framework allows us to evaluate the welfare implications of alternative liberalization policies. Capital account and exchange rate liberalization would have allowed the Chinese central bank to better stabilize the external shocks experienced during the global financial crisis.     

Macroeconomic fundamentals and the exchange rate dynamics: A no-arbitrage macro-finance approach

In this paper, we propose an arbitrage-free international macro-finance model that links the exchange rate dynamics to macroeconomic fundamentals. Jointly using data on exchange rates, yields of zero-coupon bonds, and macroeconomic variables of the US and the Euro area, we find a close link between macroeconomic fundamentals and the exchange rate dynamics. The model-implied monthly exchange rate changes can explain about 57% variation of the observed data. The macroeconomic innovations can help capture large variation of exchange rate changes. Robustness checks show that the results also hold for other major exchange rates.     

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.      

利率市场化改革对于人民币汇率的影响

利率与汇率作为货币资金的对内价格和对外价格,二者具有统一的价值基础,并且相互影响,相互制约,共同在金融市场的资源配置中发挥着重要的作用。利率作为货币资金的对内价格,影响着居民及企业的支出和投资,利率的变化对整个金融市场乃至整个经济生活都有不容忽视的影响。汇率作为货币资金的对外价格,是开放经济条件下,外汇市场上的核心价格变量,受外汇市场、国际收支、跨国资产组合、外汇储备等因素影响。在一国宏观经济中,利率政策和汇率政策是货币政策的重要组成部分,也是一国宏观经济调控的主要政策手段。实际上,在宏观经济运行中,尤其是开放型经济,利率与汇率存在着复杂的关系,甚至有时还存在冲突。因此,对于利率与汇率在传导机制、价值基础、政策运用方面的相互关系的研究,将更有利于发挥货币政策的宏观调控效果。近年来,随着我国的改革开放逐步向纵深方向发展,利率的市场化改革也将进入攻坚阶段。当然,利率市场化改革将对整个金融体系及经济生活产生深远影响,但本文将研究重点放在利率与汇率的联动关系进而更好的研究利率市场化改革对于人民币汇率的影响。     

开放经济下的“双支柱”调控稳定效应研究

本文研究了管理浮动汇率制下我国货币政策和宏观审慎政策双支柱的调控稳定效应。首先,本文从实证层面考察了人民币汇率升贬值对央行货币政策的非对称影响。接着,本文构建了包含银行部门与货币错配的开放宏观经济模型,重点分析了在面对美联储加息、人民币贬值压力的情况下,货币政策(包括对汇率的反应)和宏观审慎政策(对外债的逆周期调节)的配合如何影响宏观经济和金融的稳定。结论表明,如果缺少宏观审慎政策的配合,货币政策对汇率的反应将导致产出、通货膨胀和资产价格等经济金融变量的波动增大。在存在宏观审慎政策的前提下,相对于完全浮动汇率制,管理浮动汇率制从中长期看能进一步促进产出和外债等核心变量的稳定。     

人民币实际汇率与宏观经济变量之间关系的实证分析

本文在对人民币汇率与宏观经济变量之间关系的理论分析基础上，利用协整检验方法考察了1992年1季度～2003年1季度人民币实际汇率与宏观经济变量之间的关系。实证分析结果表明，模型的所有估计系数的符号与建模时设定的符号相一致，并且人民币实际有效汇率与所考察的各宏观经济变量之间存在着惟一的长期均衡关系。这种长期均衡关系的存在能从一个侧面反映出在考察期间内人民币汇率的调整和变化是适应中国宏观经济内外平衡需要的。     

Crisis, Adjustment, and Reform in Thailand's Industrial Firms

New data on Thailand's industrial firms shed light on the originsof the East Asian financial crisis and on the response of themanufacturing sector to the structural adjust-ment program supportedby the international financial institutions. Before the crisis,Thai firms had declining profitability, but they neverthelessmaintained high levels of investment, often in domesticallyoriented areas (notably the auto sector). Thai firms financedthese investments with short-term borrowing from financial institutions,which in turn borrowed short term on foreign markets. That only40 percent of firms provided audited financial statements totheir banks meant that the financial sector had poor informationfor assessing the true riskiness of these investments. The financialstructure was thus vulnerable even to small shocks. How well did the adjustment program deal with the crisis? Thaifirms had difficulty increasing their exports quickly becauseof investment in the wrong sectors, a decline in regional demand,and bottlenecks that included red tape and poor customs administration.Because of the poor export response, the brunt of adjustmenthad to come through compression of demand and of imports. Inretrospect, the macroeconomic program— which assumed quickexport recovery— was too tight.

IMF Conditionality and Country Ownership of Adjustment Programs

This article uses finance and agency theory to establish twokey propositions about International Monetary Fund (IMF) conditionalityand country ownership of IMF-supported adjustment programs.First, the authors propose that the conditionality attachedto these programs is justified. Second, the article hypothesizesthat country ownership of these programs is crucial for theirsuccess. Because IMF conditionality and country ownership areboth necessary, the challenge is designing conditionality thatmaximizes ownership while providing adequate safeguards forIMF lending. The article analyzes several recent proposals aimedat enhancing country ownership of policies contained in IMF-supportedprograms. These proposals include encouraging countries to designtheir own adjustment and reform programs, streamlining structuralconditionality, introducing flexibility in the timing of structuralpolicy measures (floating tranche conditionality), and applyingconditionality to outcomes rather than policies (outcomes-basedconditionality).
