Export Variety and Country Productivity 出口品种和国家生产力
Pub Date : 2004-09-22 DOI: 10.1596/1813-9450-3412
R. Feenstra, H. Kee
The authors study the link between export product variety and country productivity based on data from 34 industrial and developing countries, from 1982 to 1997. They measure export product variety by the share of U.S. imports on the set of goods exported by each sampled country relative to the world. It is a theoretically sound index which is consistent with within-country GDP maximization, as well as cross-country comparison. They construct country productivity based on relative endowments and product variety. Increases in output product variety improve country productivity as the new mix of output may better use resources of the economy, and improve allocation efficiency. Such effects depend on the elasticity of substitution in production between the different varieties. The more different the varieties are in terms of production, the more efficient it is to use the endowments of the economy when a new variety is available, which leads to productivity gains. In addition, as suggested in the literature, export product variety depends on trade costs, such as tariffs, distance, and transport costs. Such trade cost variables are used as instruments to help the authors identify the effects of export variety on country productivity. Empirical evidence supports their hypothesis. Overall, while export variety accounts for only 2 percent of cross-country productivity differences, it explains 13 percent of within-country productivity growth. A 10 percent increase in the export variety of all industries leads to a 1.3 percent increase in country productivity, while a 10 percentage point increase in tariffs facing an exporting country leads to a 2 percent fall in country productivity.
作者根据1982年至1997年34个工业国家和发展中国家的数据,研究了出口产品种类与国家生产率之间的关系。他们衡量出口产品种类的方法是,美国进口商品占每个抽样国家出口商品总量的比例。它是一个理论上合理的指标,既符合国内GDP最大化,又符合跨国比较。他们根据相对禀赋和产品种类来构建国家生产力。产出产品种类的增加提高了国家生产率,因为新的产出结构可以更好地利用经济资源,提高配置效率。这种影响取决于生产中不同品种之间替代的弹性。品种在生产方面的差异越大,当有新品种可用时,利用经济禀赋的效率就越高,从而导致生产率的提高。此外,如文献所述,出口产品的种类取决于贸易成本,如关税、距离和运输成本。这些贸易成本变量被用作工具,以帮助作者确定出口品种对国家生产力的影响。经验证据支持他们的假设。总体而言,虽然出口品种只占跨国生产率差异的2%,但它解释了国内生产率增长的13%。所有行业的出口品种每增加10%,国家生产率就会提高1.3%,而出口国面临的关税每增加10个百分点,国家生产率就会下降2%。

Basel Ii and Developing Countries: Sailing Through the Sea of Standards 巴塞尔协议Ii和发展中国家:在标准的海洋中航行
Pub Date : 2004-09-01 DOI: 10.1596/1813-9450-3387
A. Powell
Despite recently announced delays, Basel II - the new standard for bank capital - is due to be completed this year for implementation in the 13 Basel Committee member countries by the end of 2006. Should the other 170 plus member countries of the World Bank also adopt Basel II? Basel II was not written with developing countries in mind, but that does not necessarily mean that there is nothing in it for developing countries or that it can be ignored. Basels I and II represent a wide Sea of Standards. This paper suggests five alternative island-standards and five navigational tools to help countries choose their preferred island within the sea. It is suggested that for some developing countries the standardized approach will yield little in terms of linking regulatory capital to risk, but that countries may need many years of work to adopt the more advanced internal rating-based approach. The paper then proposes a centralized rating-based approach as a transition measure. The paper also makes proposals regarding a set of largely unresolved cross-border issues.
尽管最近宣布推迟,但巴塞尔协议II——银行资本的新标准——将于今年完成,并于2006年底在巴塞尔委员会的13个成员国实施。世界银行的其他170多个成员国是否也应采纳《新巴塞尔协议》?《新巴塞尔协议》的制定并没有考虑到发展中国家,但这并不一定意味着它对发展中国家没有任何好处,也不意味着它可以被忽视。巴塞尔协议I和巴塞尔协议II代表了广泛的标准海洋。本文提出了五种备选岛屿标准和五种导航工具,以帮助各国在海上选择他们喜欢的岛屿。有人建议,对一些发展中国家来说,标准化方法在将管制资本与风险联系起来方面收效甚微,但这些国家可能需要多年的工作才能采用更先进的基于评级的内部方法。然后,本文提出了一种基于集中评级的方法作为过渡措施。该文件还就一系列基本上尚未解决的跨境问题提出了建议。

Patterns of Industrial Development Revisited: The Role of Finance 重新审视工业发展模式:金融的作用
Pub Date : 2002-08-31 DOI: 10.1596/1813-9450-2877
Raymond J. Fisman, Inessa Love
The authors reexamine the role of financial market development in the intersectoral allocation of resources. First, they characterize the assumptions underlying previous work in this area, in particular, that of Rajan and Zingales (1998). The authors argue that Rajan and Zingales (1998) implicitly test whether financial intermediaries allow firms to better respond to global shocks to growth opportunities. Second, the authors propose a more efficient alternative test of this hypothesis using statistical techniques developed in the social networks literature. Specifically, they find that countries have more highly correlated growth rates across sectors when they have well-developed financial markets, suggesting that financial markets play an important role in allowing firms to take advantage of global growth opportunities. These results are particularly strong when financial development takes into account both the level and composition of financial development: private banking appears to play a particularly important role in resource allocation. The authors'technique allows them to further distinguish between the"growth opportunities"hypothesis stated above and the alternative"finance and external dependence"hypothesis, which implies that countries with similar levels of financial development should specialize in similar sectors. They do not find evidence to support this alternative view of finance and development.
作者重新审视了金融市场发展在部门间资源配置中的作用。首先,他们描述了该领域先前工作的假设,特别是Rajan和Zingales(1998)的假设。作者认为,Rajan和Zingales(1998)隐含地测试了金融中介机构是否允许企业更好地应对全球增长机会冲击。其次,作者提出了一种更有效的替代检验方法,使用社会网络文献中开发的统计技术。具体来说,他们发现,当一个国家拥有发达的金融市场时,其各个部门的相关增长率更高,这表明金融市场在允许企业利用全球增长机会方面发挥着重要作用。当金融发展考虑到金融发展的水平和构成时,这些结果尤其明显:私人银行似乎在资源配置中发挥了特别重要的作用。作者的技术使他们能够进一步区分上述“增长机会”假说和另一种“金融和外部依赖”假说,这意味着具有相似金融发展水平的国家应该专注于类似的部门。他们没有找到证据来支持这种关于金融和发展的另类观点。

Regional Cooperation, and the Role of International Organizations and Regional Integration 区域合作,以及国际组织和区域一体化的作用
Pub Date : 2002-07-01 DOI: 10.1596/1813-9450-2872
M. Schiff, L. Winters
The authors examine regional cooperation among neighboring countries in the area of regional public goods. These public goods include water basins (such as lakes, rivers, and underground water), infrastructure (such as roads, railways, and dams), energy, and the environment. Their analysis focuses on developing countries and the potentially beneficial role that international organizations and regional integration may play in bringing the relevant countries to a cooperative equilibrium. A major problem in reaching a cooperative solution is likely to be the lack of trust. If neighboring countries do not trust each other because of past problems, they may fail to reach a cooperative solution as each tries to maximize its gain from the regional public good. These strategies typically do not account for spillover effects and ultimately leads to losses for all parties. Other constraints on reaching a cooperative solution are its complexity and the financial requirements. Two types of institutions may help resolve some or all of these problems. International organizations can help with trust, expertise, and financing. The United Nations and the World Bank have been involved in a number of such projects in Africa, Asia, and elsewhere, and have been successful in helping parties reach cooperative solutions. Regional integration agreements, though not necessary for regional cooperation, may also be helpful by embedding the negotiations on regional cooperation in a broader institutional framework. The authors examine these issues with the support of both analysis and a number of case studies.
作者从区域公共产品的角度考察了邻国之间的区域合作。这些公共产品包括流域(如湖泊、河流和地下水)、基础设施(如公路、铁路和水坝)、能源和环境。他们的分析集中于发展中国家以及国际组织和区域一体化在使有关国家达到合作平衡方面可能发挥的潜在有益作用。达成合作解决方案的一个主要问题可能是缺乏信任。如果邻国之间因为过去的问题而不信任对方,就会因为各自都想从地区公共产品中获得最大利益而无法达成合作解决方案。这些策略通常没有考虑溢出效应,最终导致各方都蒙受损失。达成合作解决方案的其他制约因素是其复杂性和财务需求。两种类型的机构可能有助于解决部分或全部这些问题。国际组织可以在信任、专业知识和资金方面提供帮助。联合国和世界银行参与了非洲、亚洲和其他地区的一些此类项目,并成功地帮助各方达成合作解决方案。区域一体化协定虽然不是区域合作所必需的,但也可能有助于将关于区域合作的谈判纳入更广泛的体制框架。作者在分析和一些案例研究的支持下研究了这些问题。

Is Russia Restructuring? New Evidence on Job Creation and Destruction 俄罗斯正在重组吗?关于创造和破坏就业的新证据
Pub Date : 2001-07-17 DOI: 10.1596/1813-9450-2641
H. Broadman, F. Recanatini
The authors explorethe labor dynamics of Russian enterprise restructuring, empirically assessing how patterns of job creation and destruction are related to various aspects of enterprise restructuring across firms in different sectors and regions, and to different forms, sizes, vintages, and performance characteristics of ownership. Evidence from case studies - based on more than 50 site visits in 2000 - suggests that jobs have been destroyed, but only to a limited degree in some sectors and regions, largely because of institutional and incentive constraints and a still-widespread"socialist"corporate culture. Jobs have been created - particularly in sectors where devaluation had the most pronounced effect on important substitution and export promotion - but only slowly, mostly for lack of skilled workers and because regional mobility is limited. Labor turnover appears higher within regions than across regions. Newly available data for 1996 - 99 (provided by Goskomstat) for about 128,000 enterprises in 24 industrial sectors in Russia's 89 regions indicates that the typical firm has experienced only modest downsizing - about 12 percent - in number of employees. Smaller firms have entered, and larger, mature businesses have exited some sectors. Except for a lull in 1998, the rate of job creation has steadily increased and the rate of job destruction has declined, dropping substantially in 1998 - 99."Voluntary"worker separations remain the main - and growing - form of layoff, and the proportion of layoffs through redundancies is shrinking (now about 4 percent of total separations). Firm size and net employment growth are not statistically related, but form of ownership seems to matter. Firm size is also statistically correlated (positively) with profitability, but restructuring through changes in net employment growth appears not to be. It seems Russian restructuring needs to become more efficient.
作者探讨了俄罗斯企业重组的劳动力动态,实证评估了就业创造和破坏模式如何与不同部门和地区的企业重组的各个方面以及不同形式、规模、年份和所有权的绩效特征相关。基于2000年50多次实地考察的案例研究证据表明,就业机会已经被摧毁,但只是在某些部门和地区受到有限程度的破坏,这主要是因为制度和激励方面的限制,以及仍然普遍存在的“社会主义”企业文化。创造了就业机会- -特别是在贬值对重要替代品和促进出口产生最显著影响的部门- -但速度很慢,主要是因为缺乏熟练工人和区域流动性有限。区域内的劳动力流动率似乎高于区域间的。1996 - 1999年俄罗斯89个地区24个工业部门约128 000家企业的最新数据(由Goskomstat提供)表明,典型的公司在雇员人数方面只经历了适度的缩减- -约12%。规模较小的公司进入了一些行业,规模较大的成熟企业退出了一些行业。除了1998年的停顿外,就业机会的创造率稳步上升,而就业机会的破坏率则有所下降,在1998 - 99年大幅下降。“自愿”员工离职仍然是裁员的主要形式,而且这种形式在不断增长,通过裁员而裁员的比例正在缩小(目前约占总裁员的4%)。企业规模和净就业增长在统计上并不相关,但所有权形式似乎很重要。企业规模在统计上也与盈利能力呈正相关,但通过改变净就业增长进行重组似乎并非如此。俄罗斯的重组似乎需要变得更有效率。

Restructuring Uganda's Debt: The Commercial Debt Buy-Back Operation 乌干达债务重组:商业债务回购操作
Pub Date : 1999-11-30 DOI: 10.1596/1813-9450-1409
K. Kapoor
Uganda's commercial debt buy-back operation was financed by the International Development Association's Debt Reduction Facility (IDA Facility), with cofinancing from the governments of Germany, the Netherlands, and Switzerland and the European Union. Commercial debt service is a serious burden to many low-income economies. Yet, although the IDA Facility has existed since 1989, only a handful of countries have been able to avail themselves of its resources. That is not altogether surprising: commercial debt buy-backs can be extremely complex, requiring substantial preparation for a well-articulated external debt strategy based on comprehensive data. One objective in describing Uganda's operation is to discuss the requirements of the IDA Facility and to shed light on how Uganda satisfied them and on which areas needed special attention. Uganda's offer to buy back its uninsured commercial debt at a discout of 88 percent of face value was extremely successful. Of the total eligible debt of US $188 million, Uganda bought back debt worth US $153 million, reflecting a participation rate by creditors of 80 percent. As a result, most of Uganda's commercial debt has been eliminated. The remaining commercial obligations accrue to creditors that either have work in progress or that hold some form of security or collateral for their claims. Uganda's debt problems are far from resolved. Much of the country's Paris Club debt is ineligible for rescheduling because it was contracted after the cutoff date. Arrears owed to non-OECD bilateral creditors have continued to mount, as these creditors have resisted restructuring Uganda's obligations to them. And servicing that part of multilateral debt that is nonconcessional or less concessional also is a burden. Resolving Uganda's external debt problem will require concerted action on several fronts: 1) continued economic reform; 2) vigorous pursuit of export diversification and growth; and 3) no letup in seeking creative ways to restructure the debt portfolio. Uganda must find grant funding wherever possible, or contract only the most concessional debt.
乌干达的商业债务回购行动由国际开发协会的减债基金(IDA基金)提供资金,德国、荷兰、瑞士政府和欧盟共同提供资金。商业偿债是许多低收入经济体的严重负担。然而,尽管开发协会融资机制自1989年以来一直存在,但只有少数国家能够利用其资源。这并不完全令人惊讶:商业债务回购可能极其复杂,需要为基于全面数据的清晰的外债战略做大量准备。描述乌干达运作的一个目的是讨论开发协会融资的要求,并阐明乌干达如何满足这些要求以及需要特别注意哪些领域。乌干达以票面价值88%的折扣回购其无保险商业债务的提议非常成功。在1.88亿美元的合格债务总额中,乌干达回购了1.53亿美元的债务,反映出债权人的参与率为80%。因此,乌干达的大部分商业债务已被消除。其余的商业债务由债权人承担,这些债权人要么有正在进行的工作,要么为其债权持有某种形式的担保或抵押品。乌干达的债务问题远未解决。该国巴黎俱乐部(Paris Club)的大部分债务没有资格重新安排偿还期限,因为这些债务是在截止日期之后签订的。欠非经合发组织双边债权国的欠款继续增加,因为这些债权国拒绝调整乌干达对它们的义务。偿还那部分非减让性或减让性较低的多边债务也是一种负担。解决乌干达的外债问题需要在几个方面采取协调一致的行动:1)继续进行经济改革;2)大力追求出口多元化和增长;3)继续寻求重组债务组合的创新方式。乌干达必须尽可能找到赠款资金,或者只签订最优惠的债务。

An Empirical Model of Sunk Costs and the Decision to Export 沉没成本与出口决策的实证模型
Pub Date : 1999-11-30 DOI: 10.1596/1813-9450-1436
Mark J. Roberts, J. Tybout
Exports respond unpredictably to a change in real exchange rates, suggests evidence from the 1980s. Recent theoretical work explains this as a consequence of the sunk costs associated with breaking into foreign markets. Sunk costs include the cost of packaging, upgrading product quality, establishing marketing channels, and accumulating information on demand sources. The authors use micro panel data to estimate a dynamic discrete-choice model of participation in export markets, a model derived from the Krugman-Baldwin sunk-cost hysteresis framework. Applying the model to data on manufacturing plants in Colombia (1981-89), they test for the presence of sunk entry costs and quantify the importance of those costs in explaining export patterns. The econometric results reject the hypothesis that sunk costs are zero. The results, which control for both observed and unobserved sources of plant heterogeneity, indicate that prior export market experience has a substantial effect on the probability of exporting, but its effect depreciates fairly quickly. The reentry costs of plants that have been out of the export market for a year are substantially lower than the costs of a first-time exporter.

上世纪80年代的证据表明,出口对实际汇率变化的反应是不可预测的。最近的理论研究将此解释为与打入国外市场相关的沉没成本的结果。沉没成本包括包装成本、提升产品质量成本、建立营销渠道成本、积累需求源信息成本。作者使用微观面板数据来估计出口市场参与的动态离散选择模型,该模型源自克鲁格曼-鲍德温沉没成本滞后框架。他们将该模型应用于哥伦比亚制造工厂(1981- 1989)的数据,检验沉没进入成本的存在,并量化这些成本在解释出口模式中的重要性。计量经济学结果否定了沉没成本为零的假设。在控制了观察到的和未观察到的植物异质性来源的情况下,结果表明,先前的出口市场经验对出口概率有实质性影响,但其影响衰减得相当快。已经退出出口市场一年的工厂重新进入市场的成本大大低于首次出口的成本。然而,在退出出口市场一年之后,再进入成本与进入成本并无显著差异。工厂特征也与出口行为有关:企业拥有的大型老工厂比其他工厂更有可能出口。与宏观经济条件和沉没成本的变化相比,工厂成本和需求条件的变化对出口利润率的影响要小得多。在全球经济衰退期间,打入国外市场似乎尤其困难。

The authors use micro panel data to estimate a dynamic discrete-choice model of participation in export markets, a model derived from the Krugman-Baldwin sunk-cost hysteresis framework. Applying the model to data on manufacturing plants in Colombia (1981-89), they test for the presence of sunk entry costs and quantify the importance of those costs in explaining export patterns. The econometric results reject the hypothesis that sunk costs are zero. The results, which control for both observed and unobserved sources of plant heterogeneity, indicate that prior export market experience has a substantial effect on the probability of exporting, but its effect depreciates fairly quickly.

Mutual Fund Investment in Emerging Markets: An Overview 新兴市场共同基金投资综述
Pub Date : 1999-11-30 DOI: 10.1093/WBER/15.2.315

International mutual funds are one of the main channels for capital flows to emerging economies. Although mutual funds have become important contributors to financial market integration, little is known about their investment allocation, and strategies. The authors provide an overview of mutual fund activity in emerging markets. First, they describe international mutual funds' relative size, asset allocation, and country allocation. Second, they focus on fund behavior during crises, by analyzing data at the level of both investors, and fund managers. Among their findings: Equity investment in emerging markets has grown rapidly in the 1990s, much of it flowing through mutual funds. Collectively, these funds hold a sizable share of market capitalization in emerging economies. Asian, and Latin American funds achieved the fastest growth, but are smaller than domestic U.S. funds and world funds. When investigating abroad, U.S. mutual funds invest more in equity than in bonds. World funds invest mainly in developed nations (Canada, Europe, Japan, and the United States). Ten percent of their investment is in Asia, and Latin America. Mutual funds usually invest in a few countries within each region. Mutual fund investment was very responsive to the crises of the 1990s. Withdrawals from emerging markets during recent crises were large, which squares with existing evidence of financial contagion. Investments in Asian, and Latin American mutual funds are volatile. Because redemptions, and injections are large, relative to total funds under management, fund's flows are not stable. The cash held by managers during injections, and redemptions does not fluctuate significantly, so investors' actions are typically reflected in emerging market inflows, and outflows.
国际共同基金是资本流向新兴经济体的主要渠道之一。尽管共同基金已成为金融市场一体化的重要贡献者,但人们对它们的投资配置和策略知之甚少。作者概述了新兴市场的共同基金活动。首先,他们描述了国际共同基金的相对规模、资产配置和国家配置。其次,他们通过分析投资者和基金经理两个层面的数据,关注基金在危机期间的行为。他们的发现包括:新兴市场的股票投资在上世纪90年代迅速增长,其中很大一部分是通过共同基金流入的。总的来说,这些基金在新兴经济体的市值中占有相当大的份额。亚洲和拉丁美洲的基金增长最快,但低于美国国内基金和世界基金。在海外考察时,美国共同基金对股票的投资多于债券。世界基金主要投资于发达国家(加拿大、欧洲、日本和美国)。他们10%的投资在亚洲和拉丁美洲。共同基金通常投资于每个地区的几个国家。共同基金投资对上世纪90年代的危机反应非常迅速。在最近几次危机中,新兴市场的撤资规模很大,这与金融危机蔓延的现有证据相符。亚洲和拉美共同基金的投资波动较大。由于赎回和注入相对于管理下的资金总额很大,基金的流动并不稳定。基金经理在注资和赎回期间持有的现金不会出现大幅波动,因此投资者的行为通常反映在新兴市场的流入和流出上。

How Stronger Protection of Intellectual Property Rights Affects International Trade Flows 加强知识产权保护如何影响国际贸易流动
Pub Date : 1999-02-01 DOI: 10.1596/1813-9450-2051

Intellectual property rights affect international trade flows when protected goods move across national boundaries. And intellectual property rights have grown in importance as the share of knowledge-intensive or high-technology products in international trade has doubled (from 12 percent in 1980 to 24 percent in 1994). The authors report new evidence about how protecting intellectual property rights affects international trade flows of nonfuel trade products. Employing a gravity model of bilateral trade, they estimate the effects of increased protection on a cross-section of 89 x 88 countries. To address estimation problems associated with zero trade flows between countries, they adopt a bivariate distributed probit regression mode. Their results confirm previous findings: stronger protection of intellectual property rights increase bilateral trade flows of manufactured nonfuel imports. But the results do not hold for trade flows in high technology, where the effect of protection intellectual property rights was found to be insignificant.
当受保护的商品跨越国界时,知识产权会影响国际贸易流动。随着知识密集型或高科技产品在国际贸易中的份额翻了一番(从1980年的12%增加到1994年的24%),知识产权的重要性也日益增强。作者报告了保护知识产权如何影响非燃料贸易产品国际贸易流动的新证据。他们采用双边贸易的重力模型,估计了加强保护对89 × 88个国家的影响。为了解决与国家间零贸易流量相关的估计问题,他们采用了双变量分布概率回归模型。他们的研究结果证实了之前的发现:加强知识产权保护会增加非燃料制成品进口的双边贸易流量。但这一结果并不适用于高科技领域的贸易流动,研究发现,在高科技领域,保护知识产权的效果不显著。

Financial Sector Adjustment Lending: A Mid-Course Analysis 金融部门调整贷款:中期分析
Pub Date : 1997-08-01 DOI: 10.1596/1813-9450-1804
Robert J. Cull
Nearly 100 countries have experienced bank insolvencies in the past 20 years. Weakness in the financial sectors of many countries is reflected in the size of the insolvencies -in many cases, the cost of bailout exceeded 15 percent of GDP- and the fact that these crises often recur. Because a strong financial sector is important for economic growth, the World Bank has increasingly granted loans with conditions attached to achieve specific financial sector reforms. The Bank often employs financial sector adjustment loans (FSALs) or, in poorer countries, credits (FSACs). FSALs are generally more comprehensive than other types of interventions and tend to concentrate on the reform areas most closely linked to the operations of deposit banks. Since 1990, their main focus has shifted from improving prudential regulations and correcting interest rate distortions to privatizing and recapitalizing banks. The author examines whether 1) initial conditions in a recipient country explain a substantial amount of the variation in intervention outcomes (as measured by post-intervention financial deepening) and 2) whether the changing nature of interventions has had implications for their success. He finds that: 1) the decline in post-intervention performance since 1990 cannot be attributed solely toinitial macroeconomic and financial sector conditions in the recipient country. 2) When initial macroeconomic and financial sector conditions were controlled for, certain types of reform, especially those dealing with prudential regulations, were associated with relatively large increases in the ration of money supply (M2) to GDP. Those dealing with recapitalization have also been relatively successful, especially when they also tackled prudential regulation or banking supervision. Those that focused on supervision did not, on average, substantially outperform those that did not, on average, focus on supervision. And reform focused on bank privatization was associated with much less financial deepening three years after the intervention. 3) In addition to reform aimed at institutional strengthening, the reform environment itself had a substantial impact on intervention outcomes. Financial deepening was positively associated with macroeconomic stability (low inflation) and an initially underdeveloped financial sector. 4) As the Bank's operational directives suggest, some macroeconomic stability is important for the success of financial sector interventions, especialy those that incorporate interest rate liberalization. While it may be best to move more aggressively on financial reform when macroeconomic circumstances are favorable,"visible"reform (such as privatization or interest rate deregulation) should be slowed down rather than abandoned in less fortunate circumstances. By contrast, less visible institution-building efforts should be continued regardless of macroeconomic conditions.
近100个国家在过去20年经历了银行破产。许多国家金融部门的弱点反映在破产的规模上——在许多情况下,救助的成本超过了GDP的15%——以及这些危机经常重演的事实。由于强大的金融部门对经济增长至关重要,世界银行越来越多地提供附加条件的贷款,以实现具体的金融部门改革。世行经常采用金融部门调整贷款(FSALs),或者在较贫穷的国家采用信贷(FSACs)。金融稳定援助一般比其他类型的干预更全面,往往集中于与存款银行业务最密切相关的改革领域。自1990年以来,它们的主要重点已从改善审慎监管和纠正利率扭曲转向对银行进行私有化和资本重组。作者考察了1)受援国的初始条件是否解释了干预结果的大量变化(通过干预后的金融深化来衡量),以及2)干预措施性质的变化是否对其成功产生了影响。他发现:1)自1990年以来干预后绩效的下降不能仅仅归因于受援国最初的宏观经济和金融部门状况。2)当最初的宏观经济和金融部门条件得到控制时,某些类型的改革,特别是那些涉及审慎监管的改革,与货币供应量(M2)与GDP之比的相对大幅增加有关。那些处理资本重组的措施也相对成功,尤其是在它们同时处理审慎监管或银行监管的情况下。平均而言,那些注重监管的公司的表现并没有明显优于那些不注重监管的公司。以银行私有化为重点的改革在干预三年后的金融深化程度大大降低。3)除了旨在加强制度的改革外,改革环境本身对干预结果也有实质性影响。金融深化与宏观经济稳定(低通胀)和最初不发达的金融部门呈正相关。4)正如银行的业务指示所表明的那样,一定程度的宏观经济稳定对于金融部门干预的成功是重要的,特别是那些包括利率自由化的干预。虽然在宏观经济环境有利的情况下更积极地进行金融改革可能是最好的,但在不太幸运的情况下,“可见的”改革(如私有化或放松利率管制)应该放慢速度,而不是放弃。相比之下,无论宏观经济条件如何,都应继续进行不太明显的体制建设努力。
