This paper attempts to understand how price volatility affects the political transition of a resource-rich nation. Two states reflect price volatility: ‘high prices’ and ‘low prices’. We argue that whether or not political transition (i.e., a switch from one regime to another) will take place in a particular state depends critically on the kind of goods a country produces. If the main economic activity in a country is the extraction of “point-source” resources such as oil that demands capital-intensive production, the opportunity cost of switching the existing regime does not alter if the price of the resource changes but the benefit becomes more lucrative. Therefore, the incumbent group is most vulnerable during ‘high prices’. If the main economic activity of the nations is the production of “diffused resources” such as coffee that requires labor, prices do affect the opportunity cost. Nations concentrating in these commodities face acute political crisis during downturns.  相似文献

A bstract Economic rent in general, and oil rent in particular, is an historically-specific, social category, reflective of unique property relations , which goes beyond the conventional notion of physical scarcity prevailing in economics literature Neither the Ricardian theory nor the neoclassical general equilibrium theory suitably explain the nature of the capital-land relation and convey an understanding of the priority of their mutual interaction within the production process Being an effect of specific property relation, the phenomenon of rent merely assumes the status of a special category applicable to the concrete conditions of some industries Hence, political economy lacks a general theory of rent
The concept of oil rent is based on the potentially conflicting interaction of ownership of oil reserves , and that of the oil leases , within the global oil industry The oil rent is the result of the transformation of the existing differential productivities of oil-producing regions within the global oil industry The formation of global oil prices and differential oil rents rest on the global competition which has become a distinguishing feature of this industry since the early 1970s  相似文献

In biophysical terms, such as energy return on investment (EROI), energy sources for the global economy have grown more expensive over the last few decades. This trend is likely to be more pronounced in the near-term future as conventional oil and gas are depleted and difficult-to-extract unconventional oil and gas become a larger part of the fossil-fuel supply. On the one hand, this will lead to “energy sprawl”—the growth of the energy sector, as this sector consumes a much larger portion of the energy it extracts—leaving less energy surplus for other sectors. On the other hand, we will see an unsustainable imbalance between the fuel prices that fossil-fuel companies will need to meet their costs and the fuel prices that the larger economy can afford to pay. This article reviews the historical role of inexpensive energy in economic growth, discusses the declining availability of conventional oil resources, and examines the increasing reliance on expensive, unconventional petroleum resources such as shale oil in the United States.  相似文献

In this article, we survey the theory and evidence linking fluctuations in energy prices to those in aggregate economic activity. We then examine the implications of this research for both monetary policy and energy policy in response to oil price shocks. The currently available research seems to provide relatively reliable guidance for monetary policy. Because the precise channels through which oil price shocks affect economic activity are only partially known, however, research offers less guidance about how countries should design energy policy should cope with oil price shocks.  相似文献

This article analyses the changing trends in regional economic development policy delivery in multilevel governance systems. Although the imperatives of coordination of public policy interventions across multiple levels has generally been recognized, not enough attention has been given to how different political systems actually adapt their institutional and policy designs to effectively operate in the emergent complexity of multilevel governance systems. The article focuses on regional economic development policy governance in the province of Ontario, Canada over the past three decades, drawing insights from new regionalism, organization theory and governance literature to examine the prospects and challenges of policy delivery in politically complex multilevel systems. The case study illustrates how regional economic development policy is increasingly dictated by complex environmental and institutional forces of multilevel governance that are shaped by the particular character of a political system.  相似文献

Despite periodic rises in commodity prices, resource-rich African countries have been characterised by state failure and low long-term economic growth. Competing explanations for the resource curse are examined with a particular focus on political institutions. The effective privatisation of states is considered within an alternative theoretical framework of non-democratic governance and non-market economics. Given the nature of many African governments, international initiatives to encourage the development of effective markets and democracy may be inadequate to prevent increased resource rents from consolidating existing elites and their patronage regimes.  相似文献

Two oil price shocks changed the pattern of cheap oil. The first was the Arab embargo on oil exports in 1973. Oil prices rose five fold. In 1978, the second was the fall of Shah Iran. Prices soared to $80–$100 a barrel in today’s prices. In 1960, OPEC was established and since then it has been a considerable political and economic force in the oil market. Two thirds of the world’s oil reserves belong to OPEC members. OPEC is accused of being responsible for most of the price increases due to their production cuts and market power. This paper provides a general framework to examine the role of OPEC in affecting oil prices through the extracted quantities. A mathematical model is developed to explore the objective function of OPEC, which includes economic and political considerations. The idea is that OPEC members consider both the political support of their citizens and profits when determining oil extraction rates. This support is represented by a “harm function” which was added to the objective function of OPEC. The solution of the model lends some support for inclusion of this harm function, through which OPEC benefits from the cuts in production aimed at harming the western countries. For this harm function to be meaningful empirically, OPEC members should have a high harm indicator, αt. With high harm indicator values, OPEC harms itself financially. The results suggest that OPEC appears to be accepting considerable monetary setbacks to appease its citizens’ taste for harming the West. At different discount rates, the monetary losses range from about 10–20%. Solving the mathematical model required estimation of the residual demand that OPEC faces plus the cost function that applies to OPEC production. This paper reports the results of these estimations.  相似文献

In recent years, the international crude oil price has become increasingly volatile. It influences the exchange rate changes of relevant countries through economic growth, price level, international balance of payments, and other channels. Such exchange rate fluctuations have caused certain risks for the development of China’s “Belt and Road” Initiative. This article analyzes the impact of oil price changes on the exchange rates of countries. Because the fluctuation of oil prices and exchange rates has shown the characteristics of multiple time scales, this study used the empirical mode decomposition (EMD) method to obtain the long-cycle and short-cycle sequences of oil prices and the exchange rates of various countries, then analyzed the impact of oil price changes on exchange rates under different time scales. The results showed that oil price fluctuations have an impact on the exchange rate changes of countries along the “Belt and Road” under different time scales. However, this effect is asymmetric between oil-producing countries and non-oil-producing countries, and the transmission path of oil prices to exchange rates varies from cycle to cycle.  相似文献
