Essays in nonlinear macroeconomic modeling and econometrics.Atems, Bebonchu January 1900 (has links)
Doctor of Philosophy / Department of Economics / Lance J. Bachmeier / This dissertation consists of three essays in nonlinear macroeconomic modeling and econometrics. In the first essay, we decompose oil price movements into oil demand (stock market) shocks and oil supply (oil-market) shocks, and examine the response of the stock market to these shocks. We find that when oil prices are “net-increasing”, a stock market shock that causes the S&P 500 to rise by one percentage point will cause the price of oil to rise approximately 0.2 percentage points, with a statistically significant positive effect one day after the stock market shock. On the other hand, the response of the stock market to an oil market shock is a decline of 6.8 percent when the price of oil doubles. For other days, the initial response of the oil market to a stock market shock is the same as in the net oil price increase case (by construction). We then analyze the response of monetary policy to the identified stock market and oil market shocks and find that short-term interest rates respond to the stock market shocks but not the oil market shocks. Finally, we evaluate the predictive power of the decomposed stock market and oil shocks relative to the change in the price of oil. We find statistically significant gains in both the in-sample fit and out-of-sample forecast accuracy when using the identified stock market and oil market shocks rather than the change in the price of oil.
The second essay revisits the statistical specification of near-multicollinearity in the logistic regression model using the Probabilistic Reduction approach. We argue that the ceteris paribus clause invoked with near-multicollinearity is rather misleading. This assumption states that one can assess the impact of near-multicollinearity by holding the parameters of the logistic regression model constant, while examining the impact on their standard errors and t-ratios as the correlation (\rho) between the regressors increases. Using the Probabilistic Reduction approach, we derive the parameters (and related statisitics) of the logistic regression model and show that they are functions of \rho , indicating the ceteris paribus clause in the traditional account of near multicollinearity is unattainable. Monte carlo simulations in the paper confirm these findings. We also show that traditional near-multicollinearity diagnostics, such as the variance inflation factor and condition number can fail to detect near-multicollinearity. Overall, the paper finds that near-multicollinearity in the logistic model is highly variable and may not lead to the problems indicated by the traditional account. Therefore, unexpected, unreliable or unstable estimates and inferences should not be blamed on near-multicollinearity. Rather the modeler should return to economic theory or statistical respecification of their model to address these problems.
The third essay examines the correlations between income inequality and economic growth using a panel of income distribution data for 3,109 counties of the U.S. We examine the non-spatial dynamic correlations between county inequality and growth using a System GMM approach, and find significant negative relationships between changes in inequality in one period and growth in the subsequent period. We show that this finding is robust across different sample sizes. We further argue that because the space-specific time-invariant variables that affect economic growth and inequality can differ significantly across counties, failure to incorporate spatial effects into a model of growth and inequality may lead to biased results.We assume that dependence among counties only arises from the disturbance process, hence the estimation of a spatial error model. Our results indicate that the bias in the parameter for inequality amounts to about 2.66 percent, while that for initial income amounts to about 21.51 percent.

The Importance of Non-Price Competitiveness: Oil Downstream Sector in Europe / The Importance of Non-Price Competitiveness: Oil Downstream Sector in EuropeSláma, Ondřej January 2017 (has links)
This thesis investigates the role of price and non-price competitiveness factors using a relative export price index, introduced by Benkovskis and Wörz (2016), that is adjusted for changes in quality and taste. First, we replicate their model employing an updated dataset, confirming previous results. Then, the framework is used to study the recent developments in the Europe's oil product market. Given the saturation of the market, decreasing demand, and converging prices, importance of non-price competitiveness factors, such as quality, increases. The results suggest that the problems of the underinvested oil downstream industry in Northwestern European producers are caused not only by decreasing aggregate demand, high costs, and low margins, but by non-price competitiveness factors as well. We find profound improvements in product quality in CEE countries, following substantial investments into the sector and market consolidation. Both regions are at risk of rising imports of high-quality products from the Middle East, Russia and USA. This thesis provides a comprehensive picture of price and non-price competitiveness developments of all players in the highly competitive European oil downstream market.

Aplikace kooperativní teorie her pro Cournotovy oligopoly / Application of cooperative game theory in Cournot oligopolyEryganov, Ivan January 2019 (has links)
This Master’s thesis deals with the application of cooperative game theory for solving the problems of Cournot's oligopolies. The knowledge of oligopoly theory and game theory has been elaborated to build a model describing the behavior of companies at a market that meets the preconditions of Cournot's oligopoly. The definition of cooperative game is based on the -characteristic function, which takes into account, compared to classical methods, that companies which are not in the coalition are pursuing their own profits, not suppressing coalition positions. The properties of the resulting cooperative games are examined in detail, focusing on monotony and convexity. Several theorems about these properties have been derived and their economic interpretations are given. Also, the question of calculation of the -characteristic function using the best-reply dynamics algorithm is being solved, and its convergence for a given type of games is justified. The model is applied to data from the oil market, which is further characterized by the results of the cooperative game.

Oil rent and diversification facing climate challenge : The case of Saudi ArabiaRente pétrolière et diversification face au défi climatique : cas de l'Arabie Saoudite / Oil rent and diversification facing climate challenge : The case of Saudi ArabiaSoummane, Salaheddine 20 May 2019 (has links)
L'appel croissant à la mise en œuvre d'une politique climatique ambitieuse et globale devrait détério-rer les perspectives économiques des pays dépendants du pétrole. Cette thèse étudie les impacts économiques de cette transition bas-carbone ainsi que les stratégies d'atténuation possibles pour le premier exportateur de pétrole: le Royaume d'Arabie Saoudite (AS). Nous proposons une applica-tion utilisant un modèle intégré économie-énergie-environnement qui prend en compte les spécifici-tés de l’économie saoudienne comme l’ancrage de son taux de change ou encore les prix d’énergies administrés.Premièrement, en utilisant une représentation agrégée de l’économie saoudienne, nous montrons qu’un prix du pétrole plus faible résultant de la transition bas-carbone mondiale résulte en un taux de croissance marginalement bas, des excédents commerciaux significativement réduits et à un chô-mage plus élevé. Nous analysons la portée des outils dont dispose l’AS pour atténuer les impacts des politiques climatiques sur son économie. Nous estimons que l'alignement des prix de l'énergie saou-diens sur les références internationales ainsi que l’augmentation des gains d'efficacité énergétique fournissent à l’AS des sources de revenus supplémentaires. Ce cadre de modélisation permet de tes-ter des scénarios prospectifs tout en contrôlant leurs spécifications macroéconomiques.Ensuite, nous mettons en perspective ces spécifications dans un cadre multisectoriel afin d'étudier les stratégies de diversification émanant des contributions prévues déterminées au niveau national (INDC) ainsi que son programme stratégique Vision 2030. Nous concluons que la diversification économique dans les secteurs à faible intensité énergétique (industrie manufacturière, tourisme et services financiers) en augmentant les exportations et la substitution des importations, en plus de réformer l'impôt sur les sociétés offre une perspective positive par rapport à une expansion continue des industries à forte intensité énergétique (minéraux, pétrochimie et ciment). En effet, nous mon-trons que la diversification dans les secteurs à faible intensité énergétique génère une croissance plus forte et un chômage plus faible. En outre, dans le cadre de ce scénario de diversification écono-mique, l’AS dépasse ses engagements climatiques en termes de réduction des émissions de CO2. Néanmoins, l’expansion des secteurs à forte intensité énergétique résulte en une meilleure perspec-tive de la dette publique puisque le gouvernement tire des revenus plus élevés de ses participations dans les industries lourdes. Enfin, nous concluons que dans nos deux scénarios, l’AS n’atteint que partiellement ses ambitions de transition vers une économie moins dépendante du pétrole dans le cadre du programme Vision 2030, ce qui suggère que de nouvelles réformes doivent être envisagées.Cette thèse contribue à la littérature sur l’implémentation d’une politique climatique et ses consé-quences économiques pour les pays exportateurs pétrole. Notre travail fournit des estimations sur les réformes économiques à entreprendre comme stratégies d'atténuation et pourrait donc être adapté pour couvrir d'autres pays et sources d’énergie. / The increasing call for implementing a global and ambitious climate policy is expected to deteriorate economic outlook of oil-dependent countries. Our research work investigates the impact of this global low-carbon transition and the potential mitigation strategies for the largest oil exporter: The Kingdom of Saudi Arabia (KSA). We propose an application using an integrated economy-energy-environment modelling framework taking into account salient features of the Saudi economy such as the currency peg and the regulated domestic energy prices.First, using an aggregated representation of the KSA economy, we show that a weaker oil price re-sulting from the global low-carbon transition is associated with a marginally lower growth, large trade surplus accumulation loss, and higher unemployment for the KSA. We analyse what scope the KSA has to mitigate climate policy impacts. We reveal that aligning domestic energy prices with international references and achieving energy efficiency gains increases economic efficiency while improving public budget prospects. This modelling framework allows to investigate scenarios while controlling the modelling macroeconomic specifications.We refine these outlooks in a mulstisector framework that further allows investigating diversifica-tion opportunities within the Saudi Intended Nationally Determined Contribution (INDC) and its Vision 2030 program. We conclude that economic diversification into non energy-intensive sectors (manufacture, tourism, and financial services) through increasing exports and import substitution, in addition to targeting fiscal adjustments of the corporate tax, provide a positive outlook compared with a continuous expansion of energy-intensive activities (minerals, petrochemical, and cement). Indeed, we show that diversification in non-energy intensive sector generates higher growth, and lower unemployment. In addition, under our designed economic diversification plan, the KSA ex-ceeds its climate pledges in terms of targeted CO2 abatement. Nevertheless, the continuous expan-sion of energy-intensive industries is associated with a better outlook for the public debt since the government derives higher revenues from its participation in energy-intensive industries. Finally, we conclude that in our two scenarios, the KSA only partially succeeds in its transition toward a less oil-dependent economy as part of the Vision 2030 program, suggesting that further reforms are to be considered.This thesis contributes to the literature on climate policy implementation and associated economic consequences for fossil-fuel exporters. It provides insights on economic reforms as mitigation strate-gies and could be thus adapted to cover additional countries and fuels.

The Impact of IEA Reports on Oil-Related Markets陳俊源, Chen, Jiun-Yuan Unknown Date (has links)
國際能源機構(IEA)每個月的石油報告已經變成預測世界石油供給與需求一個很重要的資源。因此，我們蒐集從1990年10月到2005年12月中國際能源機構所發佈的179次宣告，利用事件研究法來衡量國際能源機構對石油相關市場的影響性。
實證結果顯示，國際能源機構的石油報告的確對石油相關市場傳達重要的資訊；而國際能源機構報告的影響效果似乎會隨著國家的不同而有所不同；在當中，石油的生產和消費量多寡、石油的密集度和油價中稅占的比例都扮演重要的角色；此外，在國際能源機構的報告中，關於預測石油需求變化這方面似乎特別被大家所重視。 / This study examines the impact of International Energy Agency's Oil Market Reports on oil-related prices. The IEA reports, published monthly in Paris, have become the primary source of world oil supply and demand forecasts. We collect 179 announcements that released by IEA over the period October 1990 to December 2005. We analyze the effects of these reports on three oil-related markets, IPE Brent Crude futures, oil industry indices and stock prices of oil companies in six countries. Moreover, we separate the effects of IEA’s forecast changes on oil supply from non-OPEC countries and oil demand from North America and China in IEA’s report.
The results confirm that IEA’s reports carry important information source for oil-related markets because more than one half of our sample companies have abnormal returns around the announcement date of IEA’s reports, and we explore these prices respond negatively to the release of IEA’s reports. We also find that the actively traded IPE Brent Crude futures contracts are affected by IEA’s reports, particularly for the change of demand in North America. Forecast changes in IEA’s reports regarding supply in non-OPEC countries, demand in North America and China show that most countries are affected by the changes in these reports. The evidences also show that British and Norwegian oil stock markets react more strongly to the change of oil demand in North America and China. Moreover, we find that participants in the oil market put more emphasis on demand changes reported by IEA, especially for China demand. And we provides empirical evidence that these companies are concerned more about the related releases of decreased demand in North America and increased demand in China. Finally, cross-sectional analysis of cumulative abnormal returns suggests that the reaction of American and Norwegian companies to IEA’s announcements is stronger than other countries, and the change of demand in North America and China and the size variable for individual company contribute to the changes of abnormal returns around IEA’s reports.

Влияние мирового нефтяного рынка на экономику Ирака : магистерская диссертация / Impact of the global oil market on the economy of IraqАльристим, М. Х. А., Alristim, M. H. A. January 2020 (has links)
The relevance of the research of the topic master's thesis is due to the increasing impact to the fact that Iraq is a vivid example of a resource-dependent country today, which is affected by the resource curse and which faces many problems. The purpose of the research: to assess the impact of the volatility of the global oil market on the economic development of Iraq and determine the prospects for its development. In accordance with the chosen of the purpose of the research is the following tasks in the work: to consider the theoretical aspects of resource-dependent countries and the features of their development; to study the theory of "resource curse" and ways to overcome it; to analyze the world oil market, especially its development and its factors; consider OPEC and its role in regulating the global oil market; to analyze the economic development of Iraq as a resource-dependent country; conduct a SWOT analysis for the economy of Iraq; develop recommendations for the development of the economy of Iraq. The scientific novelty can be attributed to highlighting the factors that make Iraq a resource-dependent country and is leading to the resource curse, as well as conducting a SWOT analysis and highlighting the weaknesses, strengths, threats and opportunities for the economy of Iraq. The practical significance of the research is determined to develop recommendations to help the country find a way out of its resource dependence. The implementation of these recommendations will help improve the situation in Iraq. / Ирак на сегодняшний день является ярким примером ресурснозависимой страны, на которую действует ресурсное проклятие и которая сталкивается со множеством проблем. Целью исследования является оценка влияния волатильности мирового рынка нефти на экономическое развитие Ирака и определение перспектив его развития. В соответствии с выбранной целью в работе были поставлены следующие задачи: рассмотреть теоретические аспекты ресурсозависимых стран и особенности их развития; изучить теорию «ресурсного проклятия» и пути его преодоления; проанализировать мировой рынок нефти, особенности его развития и его факторы; рассмотреть ОПЕК и ее роль в регулировании мирового рынка нефти; проанализировать экономическое развитие Ирака как ресурсозависимой страны; провести SWOT-анализ для экономики Ирака; разработать рекомендаций для развития экономики Ирака. К научной новизне можно отнести выделение факторов делающих Ирак ресурснозависимой страной и способствующих ресурсному проклятию, а также проведение SWOT-анализа и выделение слабых, сильных сторон, угроз и возможностей для экономики Ирака. Практическая значимость магистерской работы состоит в разработки рекомендаций, помогающих стране выйти из ресурсной зависимости. Внедрение данных рекомендаций будет способствовать улучшению ситуации в Ираке.

Kurz- und langfristige Angebotskurven für Rohöl und die Konsequenzen für den MarktSchlothmann, Daniel 20 April 2016 (has links) (PDF)
In dieser Arbeit wurden Angebotskurven für 22 bedeutende Ölförderländer ermittelt und anschließend zu globalen Angebotskurven aggregiert. Gemäß den ermittelten Angebotskurven sind nahezu alle gegenwärtig in der Förderphase befindlichen Ölprojekte in den Untersuchungsländern auch beim aktuellen Ölpreis von 35 bis 40 US-$ je Barrel unter Berücksichtigung der kurzfristigen Grenzkosten rentabel. Sollte der Ölpreis jedoch in den kommenden Jahren auf diesem Niveau verharren, wird es bis zum Jahr 2024 zu einem Angebotsengpass auf dem globalen Ölmarkt kommen, da zur Deckung der zukünftigen Nachfrage die Erschließung kostenintensiver, unkonventioneller Lagerstätten und von Lagerstätten in tiefen und sehr tiefen Gewässern notwendig ist. Damit es bis zum Jahr 2024 nicht zu einem solchen Angebotsengpass kommt, ist gemäß des ermittelten langfristigen Marktgleichgewichts ein Ölpreis von mindestens 80 (2014er) US-$ je Barrel notwendig.
