Macroeconomic Fluctuations in Developing Countries: Some Stylized Facts

This article documents the main stylized features of macroeconomicfluctuations for 12 developing countries. It presents cross-correlationsbetween domestic industrial output and a large group of macroeconomicvariables, including fiscal variables, wages, inflation, money,credit, trade, and exchange rates. Also analyzed are the effectsof economic conditions in industrial countries on output fluctuationsin the sample developing countries. The results point to manysimilarities between macroeconomic fluctuations in developingand industrial countries (procyclical real wages, countercyclicalvariation in government expenditures) and some important differences(countercyclical variation in the velocity of monetary aggregates).Their robustness is examined using different detrending procedures.     

Saving in Developing Countries: An Overview

This article reviews the current state of knowledge on the determinantsof saving rates, presenting the main findings and contributionsof the recently completed World Bank research project, ‘SavingAcross the World.’ The article discusses the basic designof the research project and its core database, the World SavingDatabase. It then summarizes the main project results and placesthem in the context of the literature on saving, identifyingthe key policy and nonpolicy determinants of private savingrates. Special attention is paid to the relationship betweengrowth and saving and the impact of specific policies on savingrates. The article concludes by introducing the studies includedin this special issue.     

Macroeconomic Adjustment and Poverty in Selected Industrial Countries

The business cycle affects the incidence of poverty, as shownby evidence from Australia, Sweden, the United Kingdom, andthe United States. Many of the poor in these countries are outsidethe labor market, and transfers are a major source of incomefor many others, but the unemployment and wage reductions thatoccur in recession increase the incidence of poverty. Majorcauses of poverty are unemployment in Australia and the UnitedKingdom and low wages in the United States. Similar cyclicaleffects are observed in Sweden, but a vast transfer programvirtually eliminates poverty. There are several policy optionsfor combating poverty caused by recession. A combination ofunemployment insurance for a limited period followed by a jobguarantee is the most effective policy toward unemployment,whereas poverty caused by low earnings can be remedied by redistributionthrough the tax system.     

Agricultural Pricing Policies in Developing Countries: An Application to Pakistan

The range of and constraints on policy instruments available to thegovernment when raising and distributing revenue can have importantconsequences for the efficiency and equity implications of pricingpolicy. The usual trade-off between equity and efficiency ismagnified. We emphasize the potential for substantial efficiency gainsfrom reforming agricultural pricing policies and from developing moredirect income transfer mechanisms. The importance of incorporatingcross-price effects is highlighted and we show that these can changethe direction of welfare-improving marginal price reforms.     

Trade Preferences to Small Developing Countries and the Welfare Costs of Lost Multilateral Liberalization

The proliferation of preferential trade liberalization overthe last 20 years has raised the question of whether it slowsmultilateral trade liberalization. Recent theoretical and empiricalevidence indicates that this is the case even for unilateralpreferences that developed countries provide to small and poorcountries, but there is no estimate of the resulting welfarecosts. This stumbling block effect can be avoided by replacingthe unilateral preferences with a fixed import subsidy, whichgenerates a Pareto improvement. More importantly, this paperpresents the first estimates of the welfare cost of preferentialliberalization as a stumbling block to multilateral liberalization.Recent estimates of the stumbling block effect of preferenceswith data for 170 countries and more than 5,000 products areused to calculate the welfare effects of the European Union,Japan, and the United States switching from unilateral preferencesfor least developed countries to an import subsidy scheme. Ina model with no dynamic gains to trade, the switch producesan annual net welfare gain for the 170 countries that adds about10 percent to the estimated trade liberalization gains in theDoha Round. It also generates gains for each group: the EuropeanUnion, Japan, and the United States ($2,934 million), leastdeveloped countries ($520 million), and the rest of the world($900 million).     

Tax Incidence Analysis of Developing Countries: An Alternative View

Misleading conclusions can be drawn from studies of tax incidencethat ignore the special features of developing countries. Incorporatingthese features can sometimes reverse the incidence pattern oftaxes relative to what is often taken to be conventional wisdom.Even where patterns are not reversed, quantitative differencescan be substantial. The "newer" views of incidence have implicationsfor tax restructuring options being considered in several developingcountries. The proposed restructuring may appear to lead onlyto a more regressive tax system because of improper incidenceanalysis.     

The Surge in Capital Inflows to Developing Countries: An Analytical Overview

After being excluded from world capital markets during the debtcrisis, many developing countries have experienced large capitalinflows during the past five years. The challenges that theseinflows pose for domestic policy in recipient countries havegenerated a substantial literature. This article presents anoverview of that literature, describing the characteristicsof the new inflows, analyzing the policy issues they raise,assessing their causes and likely sustainability, and evaluatingpotential policy responses. The desirable policy response istied to characteristics of the flows themselves as well as tothe characteristics of the recipient economy.     

浮动汇率制:发展中国家的必然选择

80年代以来,发展中国家的汇率制度发生很大变化,向浮动汇率转变的趋势明显.实现这种转变要把握时机,循序渐进.     

Urbanization in Developing Countries

The rapid urbanization in many developing countries over thepast half century seems to have been accompanied by excessivelyhigh levels of concentration of the urban population in verylarge cities. Some degree of urban concentration may be desirableinitially to reduce inter- and intraregional infrastructureexpenditures. But in a mature system of cities, economic activityis more spread out. Standardized manufacturing production tendsto be deconcentrated into smaller and medium-size metropolitanareas, whereas production in large metropolitan areas focuseson services, research and development, and nonstandardized manufacturing.The costs of excessive concentration (traffic accidents, healthcosts from exposure to high levels of air and water pollution,and time lost to long commutes) stem from the large size ofmegacities and underdeveloped institutions and human resourcesfor urban planning and management. Alleviating excessively highurban concentration requires investments in interregional transportand telecommunications to facilitate deconcentration of industry.It also requires fiscal deconcentration, so that interior citiescan raise the fiscal resources and provide the services neededto compete with primate cities for industry and population.      

Cash Flow Volatility, Prices and Price Volatility: An Experimental Study

The value of an asset is equal to the present value of its expected future cash flows. It is affected by the magnitude, timing and riskiness, or volatility, of the cash flows. We hypothesize that if the expected values of two assets?? cash flows are equal, the value of the asset with more volatile cash flows will be lower. Furthermore, we examine the impact of the volatility of cash flows on the volatility of prices. We consider a simple experimental environment where subjects trade in an asset which provides dividends from a known probability distribution. The expected value of the dividends is identical in all experimental treatments. The treatments vary with respect to the volatility of dividends. We find that when dividends are more volatile, transaction prices are lower. We also find that the volatility of prices is lower in the treatment with highly volatile dividends. In addition, as expected, trading volume is lower when cash flows are less volatile.     

Housing Policy in Developing Countries: Conjectures and Refutations

This article discusses housing policy in developing economies.It examines recent research findings in light of earlier argumentsas to the benefits of more market-oriented approaches. It alsolooks at whether the recommendations of earlier work have beenrefuted or developed in subsequent analyses and policy measures.In particular, it reviews the empirical analysis of the effectsof policy on housing supply, the richer understanding of theeffects that land market regulations have on housing affordabilityand the functioning of urban areas, and the alleged mysteriouseffects that researchers claim effective property rights haveon housing policy and on development more generally. It alsoexamines the effects of the increased emphasis on communityparticipation, showing how it helps to more fully reconcilethe incentives faced by beneficiaries of housing policy anddonors. Finally, it examines recent literature on the welfareeffects of rent control. The article shows that some of theconjectures as to the likely benefits of more market-based policyhave been refuted, but large welfare gains for poor people canstill be realized by adapting this approach. Furthermore, thisapproach appears to be gaining ground as the consensus approachto effective housing policy.      

人民币汇率波动与我国通胀、产出波动：一个扩展泰勒曲线的研究

发挥市场供求对汇率的调节作用,增强人民币汇率双向浮动弹性,是当前我国汇率体制改革的主要方向。本文在泰勒曲线的框架下考察人民币汇率波动对我国宏观经济波动和货币政策实施的影响。通过实证研究发现,1994—2006年通货膨胀波动对人民币汇率波动是不敏感的,人民币汇率传递效应不显著,人民币汇率波动对宏观经济波动没有显著的影响;2007年以后人民币汇率波动推动泰勒曲线向内移动,因此更大的人民币汇率弹性对货币政策传导和货币政策有效性是有利的,逐步扩大的人民币汇率弹性区间对我国宏观经济运行是适宜和可接受的。另外人民币汇率波动也使得泰勒曲线更加陡峭,稳定通货膨胀所导致的产出缺口波动减小了,因而更有利于货币政策当局追求一个低而稳定的通胀目标。     

我国证券市场与宏观经济波动关联性：基于小波变换和互谱分析的对比检验

本文利用小波变换和互谱分析方法,从时域和频域两个角度研究我国证券市场与宏观经济波动关联性。在小波变换下证券市场与宏观经济长短周期波动存在非一致性,短周期波动具有共变性和双向Granger因果关系,中周期波动出现一定程度的异动性、时滞性和单向Granger因果关系,而长周期波动具有完全异动性和双向Granger因果关系。相干谱和相位谱分析表明,二者长短周期波动相关性较高,中周期波动宏观经济先行,长周期波动二者具有反向共变性,这与小波变换的结论相一致。     

Brain Drain in Developing Countries

An original data set on international migration by educationalattainment for 1990 and 2000 is used to analyze the determinantsof brain drain from developing countries. The analysis startswith a simple decomposition of the brain drain in two multiplicativecomponents, the degree of openness of sending countries (measuredby the average emigration rate) and the schooling gap (measuredby the education level of emigrants compared with natives).Regression models are used to identify the determinants of thesecomponents and explain cross-country differences in the migrationof skilled workers. Unsurprisingly, the brain drain is strongin small countries that are close to major Organisation forEconomic Co-operation and Development (OECD) regions, that sharecolonial links with OECD countries, and that send most of theirmigrants to countries with quality-selective immigration programs.Interestingly, the brain drain increases with political instabilityand the degree of fractionalization at origin and decreaseswith natives' human capital.     

Capital Structures in Developing Countries

This study uses a new data set to assess whether capital structure theory is portable across countries with different institutional structures. We analyze capital structure choices of firms in 10 developing countries, and provide evidence that these decisions are affected by the same variables as in developed countries. However, there are persistent differences across countries, indicating that specific country factors are at work. Our findings suggest that although some of the insights from modern finance theory are portable across countries, much remains to be done to understand the impact of different institutional features on capital structure choices.     

Deutsche Mark–Dollar Volatility: Intraday Activity Patterns, Macroeconomic Announcements, and Longer Run Dependencies

This paper provides a detailed characterization of the volatility in the deutsche mark–dollar foreign exchange market using an annual sample of five-minute returns. The approach captures the intraday activity patterns, the macroeconomic announcements, and the volatility persistence (ARCH) known from daily returns. The different features are separately quantified and shown to account for a substantial fraction of return variability, both at the intraday and daily level. The implications of the results for the interpretation of the fundamental driving forces behind the volatility process is also discussed.     

Public Debt Management and Macroeconomic Stability: An Overview

Recent research suggests that management of the public sector’sdebt can have important effects on a country’s macroeconomicperformance. This article provides an overview of the factorsthat the recent literature has identified as important in determiningthe optimal composition of the public debt. Based on this analysis,it attempts to establish general guidelines for public debtmanagement in emerging economies. To retain market access andpromote domestic financial market development, governments shouldgenerally finance themselves at market rates using a wide varietyof securities. Beyond this general principle, the optimal compositionof the public debt involves a tradeoff between enhancing thegovernment’s anti–inflationary credibility and reducingthe vulnerability of its budget to macroeconomic shocks. Consequently,the optimal composition of the debt depends on a country’scircumstances. Debt should be heavily weighted toward long-termnominal securities for governments that have anti–inflationarycredibility and toward long-term indexed debt for those thatdo not.      

Household Saving in Developing Countries: First Cross-Country Evidence

Although most studies have relied on domestic or private sectorsaving data, this article uses household data available fromthe U.N. System of National Accounts for a sample of 10 countries.Household saving functions are estimated using combined time-seriesand cross-country observations in order to test households'responses to income and growth, rates of return, monetary wealth,foreign saving, and demographic variables. The results showthat income and wealth variables affect saving strongly andin ways consistent with standard theories. Inflation and theinterest rate do not show clear effects on saving, which isalso consistent with their theoretical ambiguity. Foreign savingand monetary assets have strong negative effects on householdsaving, which suggests the importance of liquidity constraintsand monetary wealth in developing countries.     

发展中国家的国有经济改革

伴随发达国家国有经济改革,发展中国家针对本国国有经济存在的弊端也掀起了改革浪潮。改革的核心是产权的私有化。实践表明,私有化不是万能的,政府在经济发展中的干预作用不可削弱。国有经济改革的出路不只是私有化,更重要的是理顺产权关系,改革治理结构,提高管理水平。
