An Empirical Dynamic Model of OPEC and Non-OPEC
نویسنده
چکیده
This paper estimates a dynamic model of the world oil market and tests whether OPEC countries colluded and whether non-OPEC countries behaved oligopolistically over the period 1970-2004. The model generates estimates of the shadow price of the resource with minimal functional form assumptions. Results support oligopolistic behavior among non-OPEC producers and collusion among OPEC producers except in the last 15 years. The shadow price does not rise monotonically, which is evidence for stock effects in extraction costs. The recent rise in the shadow price reflects the rising economic scarcity of oil.

The political economy of OPEC
Building on the political economy literature, we develop a conceptual model and apply it to explain the OPEC pricing behavior. We model OPEC as a cartel-of-nations where politician use two instruments: production quotas and domestic fuel consumption subsidies. Our model explains the wedge between domestic fuel prices in OPEC countries and in the rest of the world. The empirical estimates show t...
متن کاملFuture of the World Oil Market with an Expanding Role of Shale Oil: A System Dynamics Approach
In this paper, we develop a dynamic system model to predict the effects of shale oil production on demand and supply of oil. We study the interaction between demand and supply of OPEC and non-OPEC member countries and supply of shale oil, oil price, growth of the global economy, development of new oil reserves and alternative energies. In our model, OPEC acts passively and covers the market d...
متن کاملHistorical and Variance Decomposition for Oil Price, Oil Consumption, OPEC and Non-OPEC Oil Production
Abstract I n this paper, the behavior of the real oil price and OPEC and non-OPEC oil production during 1973-2013 are modelled. Interactions among OPEC, non-OPEC oil production, global oil consumption, and the real price of crude oil are estimated using a Structural VAR model (SVAR). After providing evidence for the structural breaks in oil price in 1996, the results indicate that, ac...
متن کاملA Decision Support System for OPEC oil production level based on game theory and ann
In this paper, we propose novel decision support system (DSS) named OPEC-DSS to support OPEC’s decisions on oil production level. OPEC-DSS is based on two important factors in oil prices; the first is OPEC oil production level (OPEC-PL) and the second is USA oil imports level (USA-IL). The OPEC-DSS support the analysers and decision-makers in three following issues: 1) OPEC-DSS can propose the ...
متن کاملThe Role of Intermediate and Capital Goods Imports in Non-Oil Exports in OPEC Countries: Spatial Dynamic Panel Data Approach
One of the issues discussed in the international economics literature is the type and amount of imported goods. The main reason for these disputes is the negative impact of imports on the domestic economy. On the other hand, some experts believe that there are some types of import that do not lead to increase the dependency and not reduce the sustainable development of the importing country. Th...
