Managing Price Risk in the Pakistan Wheat Market

The government intervenes in the wheat market in Pakistan toensure food security for consumers and to provide adequate andstable incomes for producers. The cost of this interventionis high, and its impact on the performance of agriculture hasbeen significantly negative. The World Bank is urging policychanges such as removing agricultural trade restrictions, pricesupports, and subsidies. However, policymakers often resistsuch reforms, fearing that they will expose the domestic marketto fluctuating international commodity prices. This article assesses the risk management needs of the sectorand evaluates whether using financial instruments—suchas commodity hedging using futures, options, or swaps—wouldimprove risk management. Simulations based on monthly data for1994 show that market-based methods of risk management couldreduce the impact of international price volatility on the domesticmarket without incurring high government cost or distortingprice signals.     

建立期货市场规避油价风险

经国务院批准,国家发展改革委决定自今年3月26日起,适当提高成品油价格水平,将汽油和柴油出厂价格每吨分别提高300元和200元,当日,北京市93号汽油涨至4．65元/升。随着我国经济的持续快速发展,国内石油消费对外依存度不断提高。国内成品油价格大幅度低于国际市场价格,与原油价格严重倒挂,发改委认为,这不利于调动炼油企业生产积极性、保障成品油市场供应和促进石油资源的节约,影响经济的平稳运行。     

Oil Price and Stock Market Synchronization in Gulf Cooperation Council Countries

Knowing that the Gulf Cooperation Council (GCC) economies are dichotomous in nature, and growth in the non-oil sector is tributary to the oil sector, we document the extent of synchronization between crude oil prices and stock markets for each of the GCC markets and for the GCC as an economic bloc. We use both the bivariate and multivariate nonparametric synchronicity measures proposed by Mink et al. (2007) to assess that linkage. We find a low to mild (mild to strong) degree of synchronization between oil price and stock market returns (volatilities). In a very few instances, we find very strong (above 80 percent) associations between these variables. These results hold irrespective of whether we assume that stock market participants form adaptive or rational expectations about the price of oil. Dynamic factor results confirm that shocks to volatility are more important than shocks to oil price returns for the GCC stock markets.     

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.      

Political Risk as a Determinant of Southern European FDI in Neighboring Developing Countries

This study analyzes foreign direct investment flows from southern European countries to one of two nearby developing regions: north African countries and new European Union member states in central and eastern Europe. As expected, good economic perspectives, human capital, and development of infrastructures attract greater investment flows. However, greater levels of political risk, measured through scales of political discretion, corruption, and economic freedom, do also attract higher inflows. Despite the fact that one might expect global flows to fall as a consequence of political risk, those from the countries in the sample increase, because they come from firms that are searching for a market niche where they can take advantage of their political capabilities.     

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.     

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.     

Oil Price Uncertainty

The theories of investment under uncertainty and real options predict that uncertainty about, for example, oil prices will tend to depress current investment. We reinvestigate the relationship between the price of oil and investment, focusing on the role of uncertainty about oil prices. We find that volatility in oil prices has had a negative and statistically significant effect on several measures of investment, durables consumption, and aggregate output. We also find that accounting for the effects of oil price volatility tends to exacerbate the negative dynamic response of economic activity to a negative oil price shock, while dampening the response to a positive oil price shock.     

Small Manufacturing Enterprises in Developing Countries

Emphasis is often placed on the promotion of small enterprisesin developing countries, particularly as a means of improvingthe lot of unskilled workers. This focus raises questions aboutthe relationship between establishment size and the patternand efficiency of factor use, and about the nature and effectsof price differentials in factor markets. This article goessome way toward answering these questions with data from surveysof small manufacturing enterprises in India and Colombia sponsoredby the World Bank and relevant material from other countries.The article also examines India's long-standing policy, unusualamong developing countries, of providing special support andprotection for small enterprises. Analyses based on disaggregateddata found that small firms are not reliably more labor-intensivethan their larger counter-parts; nor are they consistently moretechnically efficient in their use of resources. In light ofthese findings and an analysis of factor markets, this articlediscusses the general implications of the research results forindustrial policy in developing countries.

Personal Income Taxes in Developing Countries

Comparative work on income taxes in developing countries hascommonly looked at average tax rates. These rates are oftenconstructed by dividing revenue collections by some measureof private or personal income. Recent controversies have, however,focused on the incentive effects of marginal tax rates. Thisarticle develops and applies a simple methodology to comparemarginal official tax rates across a sample of fifty developingcountries. As would be expected given differences in fiscalcapacity, the poorest and the lower-middle-income countriesimpose relatively low marginal rates, and the rates for theupper-middle-income and developed countries are higher. Conversely,several low-and lower-middle-income countries' tax thresholdsstart at income levels which are low relative to their meanincome when compared with those of developed countries. Theresults warn against trying to derive information on the disincentiveeffect of a country's tax schedule from the highest marginalrate; our data show that this is not an accurate indicator ofoverall disincentive effects.     

Genuine Savings Rates in Developing Countries

Augmented measures of savings and wealth in the national accountsare critical to conceptualizing and achieving sustainable development.After developing the theory of genuine savings—traditionalnet savings less the value of resource depletion and environmentaldegradation plus the value of investment in human capital—thisarticle presents empirical estimates for developing countries.These calculations account for resource depletion and carbondioxide emissions, using consistent time series data for 1970–93.The empirical evidence shows that levels of genuine savingsare negative in a wide range of countries, particularly in Sub-SaharanAfrica, and that these countries are being progressively impoverished.Increasing the coverage of natural resources and pollutantsin our calculations would reduce the estimated levels of genuinesavings overall. The use of genuine savings measures suggestsa series of policy questions that are key to sustaining development.These are also explored, specifically the extent to which monetaryand fiscal policies, exports of exhaustible resources, strongerresource policies, and pollution abatement measures boost genuinesavings rates. For policymakers, linking sustainable developmentto genuine savings rates means that there are many possibleinterventions to increase sustainability, from the macroeconomicto the purely environmental.     

2006年石油价格展望

本文对影响2006年石油价格的因素做了系统分析。认为2006年形成油价风险的主要动因已从需求的波动转向供给的波动;2006年油价将由于供求的脆弱平衡维持高位运行的格局,并且,由于供给链中潜在的危机,油价波动性将会非常大;但在全球经济增速下降、石油需求增长放缓、石油生产国家和公司仍然在努力满足市场需求、炼油瓶颈有望缓和的大背景下,油价在2006年按2005年可比价格计不会大幅上升,不会对全球经济产生重大负面影响。

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.     

Taxation of Financial Assets in Developing Countries

In developing countries most of the financial assets are depositsat commercial banks. This article focuses on the implicit taxationof financial assets through seigniorage, reserve requirements,lending targets, and interest ceilings combined with inflation.The impact of taxation on financial deepening increases significantlywith the tax rate, as shown by cross-sectional and time seriesdata for selected countries in Sub-Saharan Africa and SoutheastAsia. The problem of measuring revenue is examined, and theefficiency cost of taxation is analyzed in a Harberger framework.Although taxes on financial assets have a low administrativecost, the excess burden caused by the misallocation of resourcesis probably a much higher fraction of revenues than that ofother taxes.

Policies on Managing Risk in Agricultural Markets

Over the past dozen years, policymakers have largely abandonedlong-standing popular approaches for addressing risk in agriculturewithout fully resolving the question of how best to manage thenegative consequences of volatile agricultural markets. Thearticle reviews the transition from past policies and describescurrent approaches that distinguish between the trade-relatedfiscal consequences of commodity market volatility and the consequencesof price and production risks for vulnerable rural householdsand communities. Current policies rely more heavily on markets,even though markets for risk are incomplete in numerous ways.The benefits and limitations of market-based instruments areexamined in the context of risk management strategies, and innovativeapproaches to extend the reach of risk markets are discussed.      

Infrastructure and Public Utilities Privatization in Developing Countries

Should governments in developing countries promote private ownershipand deregulated prices in noncompetitive sectors? Or shouldthey run publicly owned firms and regulate prices at the expenseof rents to insiders? A theoretical model is used to answerthese normative questions. The analysis focuses on the tradeoffbetween fiscal benefits and consumer surplus during privatizationof noncompetitive sectors. Privatization transfers control rightsto private interests and eliminates public subsidies, yieldingbenefits to taxpayers at the cost of increased prices for consumers.In developing countries, where budget constraints are tight,privatization and price liberalization may be optimal for lowprofitability industries but suboptimal for more profitableindustries. And once a market has room for more than one firm,governments may prefer to regulate the industry. Without a credibleregulatory agency, regulation is achieved through public ownership.
