Resource Curse or Not: A Question of Appropriability*

Whether natural resources are good or bad for a country's development are shown to depend on the interaction between institutional setting and, crucially, the types of resources possessed by the country. Some natural resources are, for economical and technical reasons, more likely to cause problems such as rent‐seeking and conflicts than others. This potential problem can, however, be countered by good institutional quality. In contrast to the traditional resource curse hypothesis, we show the impact of natural resources on economic growth to be non‐monotonic in institutional quality, and increasingly so for certain types of resources. In particular, countries rich in minerals are cursed only if they have low‐quality institutions, while the curse is reversed if institutions are sufficiently good. Furthermore, if countries are rich in diamonds and precious metals, these effects—both positive and negative—are larger.     

Resource Curse: New Evidence on the Role of Institutions

This paper attempts to provide a probable answer to a longstanding resource curse puzzle; i.e., why resource-rich nations grow at a slower rate compared with less fortunate ones. Using an innovative threshold estimation technique, the empirical results reveal that there is a threshold effect in the natural resources–economic growth relationship. We find that the impact of natural resources is meaningful to economic growth only after a certain threshold point of institutional quality has been attained. The results also shed light on the fact that the nations that have low institutional quality depend heavily on natural resources while countries with high quality institutions are relatively less dependent on natural resources to generate growth.     

Do natural resources help or hinder development? Resource abundance,dependence, and the role of institutions

The resource curse literature presents conflicting evidence on the relationship between natural resources and development. We evaluate the direct effect of resources on developmental outcomes vis-à-vis their indirect effect through the weakening of political institutions using a 3SLS instrumental variable setup that simultaneously estimates development outcomes and institutions. We find that resource abundance and resource dependence affect development outcomes through different channels. While resource abundance generally has a direct positive effect on developmental outcomes, resource dependence has a stronger negative indirect effect that operates through its negative impact on institutional quality. The results also depend on the type of development outcome considered, with more consistent positive direct effects found for physical capital measures and stronger negative indirect effects for human capital development. The use of a simultaneous framework and dual measures of resources reconciles seemingly contradictory findings in earlier work.     

Natural Resource Dependence and Economic Performance in the 1970–2000 Period

We look at the type of natural resource dependence and growth in developing countries. Certain natural resources called point‐source, such as oil and minerals, exhibit concentrated and capturable revenue patterns, while revenue flows from resources such as agriculture are more diffused. Developing countries that export the former type of products are regarded prone to growth failure due to institutional failure. We present an explicit model of growth collapse with micro‐foundations in rent‐seeking contests with increasing returns. Our econometric analysis is among the few in this literature with a panel data dimension. Point‐source‐type natural resource dependence does retard institutional development in both governance and democracy, which hampers growth. The resource curse, however, is more general and not simply confined to mineral exporters.     

The curse of natural resources in the transition economies*

The curse of natural resources is a well‐documented phenomenon for developing countries. Economies that are richly endowed with natural resources tend to grow slowly. Among the transition economies of the former ‘Eastern Bloc’, a similar pattern can be observed. This paper shows that a large part of the variation in growth rates among the transition economies can be attributed to the curse of natural resources. After controlling for numerous other factors, there is still a strong negative correlation between natural resource abundance and economic growth. Among the transition economies the prime reasons for the curse of natural resources were corruption and a neglect of basic education. In order to overcome the curse of natural resources and move to a sustainable path of development, the resource abundant transition countries should fight corruption and ensure that their resource revenues are invested in human capital or the preservation of natural capital.     

Political foundations of the resource curse

In this paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse. We show: (1) politicians tend to over-extract natural resources relative to the efficient extraction path because they discount the future too much, and (2) resource booms improve the efficiency of the extraction path. However, (3) resource booms, by raising the value of being in power and by providing politicians with more resources which they can use to influence the outcome of elections, increase resource misallocation in the rest of the economy. (4) The overall impact of resource booms on the economy depends critically on institutions since these determine the extent to which political incentives map into policy outcomes. Countries with institutions that promote accountability and state competence will tend to benefit from resource booms since these institutions ameliorate the perverse political incentives that such booms create. Countries without such institutions however may suffer from a resource curse.     

“资源诅咒”悖论国外实证研究的最新进展及其争论

许多文献证明,自然资源缺乏的国家往往依靠技术和制度创新,实现了更快的经济增长,而自然资源丰裕的国家却容易陷入资源依赖型增长陷阱,经济学家用资源诅咒来描述这一经济增长中的悖论。资源诅咒的出现激起了学者们的广泛研究兴趣,产生了大量实证研究成果。本文将从荷兰病、制度和暴力冲突三个维度,对资源诅咒的国外最新实证文献进行系统梳理,并对目前学术界存在的争论进行述评。     

China's Economic Influence in Latin America

After decades of low‐level commercial interaction, China and Latin America significantly ramped up their economic relationship in the 2000s. China has jumped to first place as an export destination for many countries, and it is a major source of imports for all countries in the Latin America/Caribbean region. While not a major source of foreign direct investment overall, China has built a strong investment presence in certain countries, particularly in the natural resource and infrastructure sectors. China's influence in Latin America has presented a great opportunity for many countries, but it has also brought new risks. Three main challenges face the region: how to mitigate the impacts of increased commodity concentration as a result of China's strong demand for natural resources; how to avoid other natural resource curse effects; and how to manage the tapering of this growth. Latin American countries' relationships with China vary widely, so there is no single, coordinated regional response.     

Conflict diamonds

‘Conflict diamonds’ refer to the fatal role that diamonds are believed to have played in several African conflicts. The article analyzes the impact of diamond rents on economic growth in light of the broader, previously discovered empirical finding of a ‘curse of natural resources.’ By extending the theory of appropriative conflict, a predator–prey game is outlined in which a rebel chooses between peaceful production and predation on natural resources controlled by the ruler. It is shown that whereas an increase in natural resources will increase the ruler's public utility investments, it might also lead to a crowding-out of labor from the formal sector to the appropriative struggle, which depresses growth. As predicted by the model, a cross-country regression analysis suggests that diamond abundance has a negative relationship with economic growth in countries with weak institutions.     

Regime types,ideological leanings,and the natural resource curse

While many consider institutional quality as a central explanatory variable when finding what causes the variance in per capita GDP growth performance of resource-abundant countries, this paper attempts to focus on more structural factors: regime type and its ideological approaches to economic policy. Several joint effects of natural resource abundance and regime type on growth are found. The natural resource curse is likely to be more severe in authoritarian regimes than democratic regimes. Among democracies, it is found that the natural resource curse is more salient in presidential regimes than in parliamentary regimes. This paper also suggests that the natural resource curse is more likely when a certain type of democratic regime coincides with a particular ideological orientation of the regime with respect to economic policy. Presidential democracies with left-wing economic policy are found to be least growth enhancing among the combinations between regime type and its economic ideology offered, given similar levels of natural resource abundance.     

Do resource dependent regions grow slower than they should?

A large literature documents a negative correlation between income growth and resource dependence. This correlation has been named the resource curse. We present evidence that suggests that the resource curse can be explained by a slow growing resource sector.     

The curse of natural resources

This paper summarizes and extends previous research that has shown evidence of a “curse of natural resources” – countries with great natural resource wealth tend nevertheless to grow more slowly than resource-poor countries. This result is not easily explained by other variables, or by alternative ways to measure resource abundance. This paper shows that there is little direct evidence that omitted geographical or climate variables explain the curse, or that there is a bias resulting from some other unobserved growth deterrent. Resource-abundant countries tended to be high-price economies and, perhaps as a consequence, these countries tended to miss-out on export-led growth.     

Do Natural Resources Depress Income Per Capita?

Most evidence for the resource curse comes from cross‐country growth regressions suffers from bias originating from the high and ever‐evolving volatility in commodity prices. These issues are addressed by providing new cross‐country empirical evidence for the effect of resources in income per capita. Natural resource dependence (resource exports) has a significant negative effect on income per capita, especially in countries with bad rule of law or bad policies, but these results weaken substantially once we allow for endogeneity. However, the more exogenous measure of resource abundance (stock of natural capital) has a significant negative effect on income per capita even after controlling for geography, rule of law and de facto or de jure trade openness. Furthermore, this effect is more severe for countries that have little de jure trade openness. These results are robust to using alternative measures of institutional quality (expropriation and corruption instead of rule of law).     

资源依赖、地理区位与城市经济增长

本文利用中国城市面板数据,探讨了资源依赖、地理区位与城市经济增长之间的相互关系。研究发现,在控制了地理区位因素之后,资源依赖与城市经济增长之间依然呈现反相关关系,"资源诅咒"在城市层面同样存在。同时,地理区位与自然资源依赖对城市经济增长存在显著的联合影响,距离重要港口城市、中心大城市和三大经济区域中心城市越近,城市经济增长对自然资源的依赖越低,其经济增长越好,优越的地理区位能够减轻资源依赖导致的"资源诅咒"效应。最后,我们的分析也表明,通过降低人力资本投资意愿,阻碍FDI流入,弱化民营经济增长等渠道,资源丰裕导致的资源依赖阻碍了城市的经济增长。     

The curse of natural resources in fractionalized countries

This paper develops a model that can explain why natural resources are a blessing for some countries, but a curse for others. In this model, natural resources cause fighting activities between rivalling groups. Fighting reduces productive activities and weakens property rights, making productive activities even less attractive. The aggregate production decrease exceeds the natural resources’ direct positive income effect if and only if the number of rivalling groups is sufficiently large. The model thus predicts that natural resources lower incomes in fractionalized countries, but increase incomes in homogenous countries. Empirical evidence supporting this prediction is provided.     

A curse or a blessing? Natural resources in a multiple growth regimes analysis

The literature on the impact of an abundance of natural resources on economic performance remains inconclusive. In this article we consider the possibility that countries may follow different growth regimes, and test the hypothesis that whether natural resources are a curse or a blessing depends on the growth regime to which an economy belongs. We follow recent work that has used a mixture-of-regressions method to identify different growth regimes, and find two regimes such that in one regime resources have a positive impact on growth, while in the other they have a negative impact or at best have no impact on growth. Our analysis of the determinants of whether a country belongs or not to the blessed resources regime indicates that the level of democracy plays an important role while education and economic institutions have no effect.     

Oil and political survival

Political economy theories on the “natural resource curse” predict that natural resource wealth is a determining factor for the length of time political leaderships remain in office. Whether resource wealth leads to longer or shorter durations in political office depends on the political incentives created by the natural resources, which in turn depend on the types of institutions and natural resource. Exploiting a sample of more than 600 political leadership durations in up to 152 countries, we find that both institutions and resource types matter for the effect that natural resource wealth has on political survival: (i) wealth derived from natural resources affects political survival in intermediate and autocratic, but not in democratic, polities; and (ii) while oil and non-lootable diamonds are associated with positive effects on the duration in political office, minerals are associated with negative duration effects.     

The curse of aid

Foreign aid provides a windfall of resources to recipient countries and may result in the same rent seeking behavior as documented in the “curse of natural resources” literature. In this paper we discuss this effect and document its magnitude. Using panel data for 108 recipient countries in the period 1960–1999, we find that foreign aid has a negative impact on institutions. In particular, if the foreign aid over GDP that a country receives over a period of 5 years reaches the 75th percentile in the sample, then a 10-point index of democracy is reduced between 0.5 and almost one point, a large effect. For comparison, we also measure the effect of oil rents on political institutions. We find that aid is a bigger curse than oil.     

煤炭资源开发对中国煤炭城市经济增长的影响——基于资源诅咒学说的经验研究

文章针对我国煤炭城市普遍存在的煤炭资源大量开采输出与经济发展水平滞后并存的反差现象,运用资源诅咒学说,通过数理模型的推导讨论了煤炭资源开发对煤炭城市长期经济增长产生的四种不同效应,并利用我国28个地级煤炭城市1997-2007年的面板数据,对煤炭资源开发与煤炭城市经济增长之间的关联效应及其传导机制进行了实证考察。结果显示:煤炭资源的开发确实束缚了煤炭城市的经济增长而产生了资源诅咒效应;固定资产投资和制造业投入对煤城经济增长的促进作用较为显著,科技投入对经济增长也表现出了一定的推动作用,但外资投入和人力资本投入的作用均不显著;煤炭城市经济发展中的要素利用效率偏低,粗放式的增长模式表现明显;煤炭资源开发主要通过削弱制造业投入、外资投入、科技投入和人力资本投入这四种传导途径来制约经济增长,其中制造业投入是作用最强的传导因素。最后文章为我国煤炭城市的经济发展提出了针对性的政策建议。     

自然资源丰裕度与中国区域经济增长——对“资源诅咒”假说的质疑

本文利用中国省际截面数据,通过构建联立方程模型,对中国区域经济层面是否存在"资源诅咒"现象进行了实证研究。计量结果显示:资源依赖度受资源丰裕度和制度质量的影响显著,具有内生性;在控制各地区的制度质量、区位变量等因素的影响后,资源丰裕度与区域经济发展并无显著相关性,因此,"资源诅咒"假说在中国区域经济层面是否成立仍然值得商榷。
