Saving in Developing Countries: An Overview 总被引:2,自引:0,他引:2
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. 相似文献

Using an event-study methodology, the article analyzes the aftermathof civil war in a cross-section of countries. It focuses oncases where the end of conflict marks the beginning of relativelylasting peace. The analysis considers 41 countries involvedin internal wars over the period 1960–2003. To providea comprehensive evaluation of the aftermath of war, a rangeof social areas is considered: basic indicators of economicperformance, health and education, political development, demographictrends, and conflict and security issues. For each indicatorthe post- and pre-war situations are compared and their dynamictrends during the post-conflict period are examined. The analysisis conducted in both absolute terms and relative to controlgroups of countries that are similar except for conflict. Thefindings indicate that even though war has devastating effectsand its aftermath can be immensely difficult, when the end ofwar marks the beginning of lasting peace, recovery and improvementare achieved. 相似文献

What causes violent crime? 总被引:1,自引:0,他引:1
This study uses panel data of intentional homicide and robbery rates for a sample of developed and developing countries for the period 1970-1994, based on information from the United Nations World Crime Surveys, to analyze the determinants of national crime rates both across countries and over time. A simple model of the incentives to commit crimes is proposed, which explicitly considers possible causes of the persistence of crime over time (criminal inertia). A panel-data based GMM methodology is used to estimate a dynamic model of national crime rates. This estimator controls for unobserved country-specific effects, the joint endogeneity of some of the explanatory variables, and the existence of some types of measurement errors afflicting the crime data. The results show that increases in income inequality raise crime rates, crime tends to be counter-cyclical, and criminal inertia is significant. 相似文献

This paper studies how the effect of trade openness on economic growth may depend on complementary reforms that help a country take advantage of international competition. This issue is illustrated with a simple Harris–Todaro model where welfare gains after trade openness depend on the degree of labor market flexibility. The paper then presents cross-country, panel-data evidence on how the growth effect of openness may depend on a variety of structural characteristics. For this purpose, the empirical section uses a non-linear growth regression specification that interacts a proxy of trade openness with proxies of educational investment, financial depth, inflation stabilization, public infrastructure, governance, labor market flexibility, ease of firm entry, and ease of firm exit. The paper concludes that the growth effects of openness may be significantly improved if certain complementary reforms are undertaken. 相似文献

This article examines empirically how domestic structural characteristicsrelated to openness and product- and factor-market flexibilityinfluence the impact of terms of trade shocks on aggregate output.Applying semistructural vector autoregressions to a panel of88 countries with annual observations for the period 1974–2000,the analysis isolates and standardizes the shocks, estimatestheir impact on GDP, and examines how this impact depends onthe domestic conditions outlined above. The article finds thatgreater trade openness magnifies the output impact of termsof trade shocks, particularly negative ones, while financialopenness reduces their impact. Flexibility of labor and firm-entryare beneficial, with labor flexibility dampening the impactof negative shocks and ease of firm-entry magnifying positiveones only. Domestic financial depth has a more nuanced rolein stabilizing the economy. Analysis of interactions acrossstructural determinants reveals complementarities among macroeconomicconditions (trade and financial openness and depth) and, separately,among microeconomic conditions (flexibility of labor marketsand ease of firm-entry). Variables across these groups tendto behave as substitutes for each other. 相似文献

This paper traces the yearly response of gross domestic product growth—both aggregated and disaggregated into its agricultural and non‐agricultural components—to four types of natural disasters: droughts, floods, earthquakes, and storms. The paper uses a methodological approach based on pooling the experiences of various countries over time. It consists of vector autoregressions in the presence of endogenous variables and exogenous shocks (VARX), applied to a panel of cross‐country and time series data. The analysis finds heterogeneous effects on a variety of dimensions. First, the effects of natural disasters are stronger on developing than on advanced countries. Second, not all natural disasters are alike in terms of the growth response they induce, and some can even have positive effects on economic growth. Third, severe disasters often carry much worse effects than moderate effects do. Fourth, the timing of the growth response varies with both the type of natural disaster and the sector of economic activity. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

This paper analyses the effect of a set of irrigation rehabilitation projects conducted over the last 10 years in Peru. The projects were conducted without the aim or the tools for a full‐fledged impact evaluation. Nevertheless, this paper attempts an evaluation through the use of alternative data sources such as household surveys and geographic information, a strategy of identification of beneficiaries and control households based on spatial proximity to the projects’ sites, and an econometric approach consisting of a double‐differencing technique. The empirical analysis is guided and interpreted with the help of a theoretical model that considers the effects of an irrigation project on the distribution of production, employment and income for different types of landowners. The paper concludes that the irrigation projects implemented in Peru had a positive impact on intended beneficiary households, but not in the way it could have been simplistically expected. The project did benefit the poor but not by increasing production in their own small plots but by providing them with better employment opportunities in larger farms. 相似文献

This article builds on a comprehensive dataset for Peru that merges municipal fiscal accounts with information about municipalities’ characteristics such as population, poverty, education, and local politics to analyze the leading factors affecting the ability of municipalities to execute the allocated budget. According to the existing literature and the Peruvian context, we divide these factors into four categories: the budget size and allocation process; local capacity; local needs; and political economy constraints. While we do find that all four factors affect decentralization, the largest determinant of spending ability is the adequacy of the budget with respect to local capacity. The results confirm the need for decentralization to be implemented gradually over time in parallel with strong capacity building efforts. 相似文献
