The oil shocks of the 1970's have revealed two important features of this commodity: I) that all countries use energy to achieve economic and social goals and 2) national stability and autonomy are closely linked to the security of its supplies. The South Pacific region has greatly experienced these effects in its pursuit of development, due to its increasing and nearly complete dependence on imported petroleum products. This is compounded by the situation of high expectations for a quality of life similar to the more developed nations of the Pacific Rim. Therefore the role of energy in these economies must be addressed before it is too late. / Thesis / Candidate in Philosophy

This thesis presents three core chapters examining different aspects of the relationship between natural resources and economic development. While addressing different questions they share several features in common: a concern with causal inference; overcoming the challenges of endogeneity between resource abundance and other characteristics of developing countries; and the use of new and novel datasets with spatially identified units of analysis. The work contributes to a rich and growing empirical literature seeking to deepen our understanding of the underlying mechanisms affecting the fortunes of resource-abundant countries. In the introductory chapter I discuss the extensive literature on this topic and in particular focus on the new generation of well-identified within-country studies, seeking to understand the empirical relationship between resources and economic development. Countries typically welcome the news of a resource discovery with joy and indeed, resource discoveries hold great economic potential. But what determines whether a country is resource rich or not? Is it more than just a chance finding, or good geology? In Chapter 2, entitled Institutions and the Location of Oil Exploration I present an investigation into this question. I examine the relationship between governance and choices of where to drill for oil. This work utilises a new dataset on exploration wells and looks at the distribution of drilling close to national borders. This allows me to identify estimates for the effect of differences in governance between neighbours. Two times out of three, investors choose to drill on the side of borders that are better governed, all other things being equal. This suggests that resource-wealth itself may be contingent on factors beyond geology, and indeed may be endogenous to the process of development. In Chapter 3, entitled The Local Effects of Resource Extraction, I turn my attention to the local economic consequences of industrial mining in Indonesia. I present a simple three-sector general equilibrium model to generate predictions for the local labour market, akin to the Corden-Neary Dutch disease model of the macroeconomy. I test the predicted effects in response to an exogenous resource sector shock by looking at mine opening or mine expansion events across three hundred mines. I test the predictions of the model, first by estimating the economic footprint from industrial mining; found to be an average of fifteen kilometre radius. I then examine the response of reported labour market activity from households surveyed in nearby communities. Here I find no evidence for a shift of local labour into the mining sector. I do find however a notable movement of labour from the traded sectors (agriculture and manufacturing) to the non-traded service sector, with a strong effect for foreign-owned mines versus domestic ones. Chapter 4, entitled Disentangling the Effects of Resource Extraction: Local Government and Investment Multipliers, examines the oil and gas boom in Indonesia from 1999-2009. Here I deploy a variety of identification strategies to attempt to disentangle the regional effects of the boom, measured in terms of district GDP. I estimate effects arising from transfers of revenue to local government. Using an instrumental variable approach I isolate the fiscal channel from resource projects. I find a positive and significant effect of increased local government revenues on district GDP over the boom decade. I then examine the spillovers from resource projects, isolating them from fiscal transfers. For districts neighbouring resource rich districts I find evidence for a modest positive effect arising from project investments, rather than fiscal transfers. In Chapter 5 I present concluding thoughts and discuss a future research agenda. I also summarise the burgeoning landscape of resource data available for within country and spatially identified studies and offer some thoughts on how this might evolve.

The main concern of this thesis is the development of political and economic relations between the PRC and the KSA. The relations that officially developed after the establishment of diplomatic relations are the focus of analysis of the thesis. By examining the historical and statistical data, the thesis assesses the factors that have cultivated and maintained the Sino-Saudi political and economic relations, as well as the implications of these bilateral links. In analysing the relations, a theoretical conception of complex interdependence has been used. The thesis first provides background on China’s policy towards the superpowers and the Middle Eastern countries between 1949 and 1989, and looks at how China and Saudi Arabia related to each other over this period. The thesis then argues that over the first decade (1990-2000) of Sino-Saudi diplomatic relations, the two countries began to lay the basis for complex interdependence between them. It highlights a number of characteristics of complex interdependence which came to exist. The thesis then goes on to examine whether, in the second decade (2001-2010) of bilateral relations, an intensification of complex interdependence ensued. The complex interdependence approach links closely with constructivist theory in terms of how this thesis is conceived. The thesis argues that China and Saudi Arabia between 1949 and 1977 shared an understanding that their ideological positions made official links between them impossible. Over the course of the following twelve years, this understanding gradually changed. The change laid the basis for the development of diplomatic relations in 1990. In the years between 1990 and 2010, the policy responses of China and Saudi Arabia to major regional events exhibited a commonality of perception. This underpinned the development of the relationship. To identify clearly the growth of Sino-Saudi relations, the thesis is divided into three time periods: 1949-89; 1990-2000; and 2001-10. The time period 1949-89 has three distinct phases: 1949-65; 1966-77; and 1978-89. The 1949-65 and 1966-97 periods are characterised by the absence of state-to-state relations between the PRC and the KSA. However, unofficial contact between Muslims on mainland China and Saudi officials and leaders was established and largely maintained. State-to-state contact only existed between the KSA and ROC governments, which shared broadly anti-Communist sentiments. During the 1978-89 phase, hope for the establishment of diplomatic relations between the PRC and the KSA was high. Some intergovernmental contact was initiated, direct communications between the leaders of the two countries were enhanced, and a joint endeavour towards the development of diplomatic ties was pursued. The 1988 missile deal smoothly accelerated the process of developing these ties. In the 1990-2000 phase, four decades after the establishment of the PRC, Sino-Saudi diplomatic relations were established. The establishment of these diplomatic relations was daunting for the ROC, which wanted to preserve the diplomatic recognition that the KSA had granted it for the preceding 45 years. The strenuous efforts of the ROC to prevent a dramatic shift of diplomatic recognition to mainland China were in vain. The 1990-2000 phase was marked by significant growth in the newly established Riyadh-Beijing diplomatic relationship. Economic interests were at the heart of the agendas of the leaders and officials of the two countries. They began to enhance co-operation and to sign agreements related to various aspects of their bilateral relations. A Memorandum of Understanding (MoU) on Oil Co-operation was concluded in 1999. The value of Sino-Saudi total trade rose by 643 percent between 1990 and 2000 and the volume of Saudi oil exports to China increased by 6,721 percent between 1991 and 2000. After nearly ten years official diplomatic relations were established, President Jiang Zemin viewed the development of bilateral relations as impressive, while Crown Prince Abdullah seemed to suggest that there was now “an intimate relationship” between the two countries, saying that he considered the PRC to be the KSA’s closest friend. The period 2001-10 is also sub-divided into two phases: 2001-05 and 2006-10. This period exhibits the three characteristics of complex interdependence that Keohane and Nye (2000) put forward in their scholarly work: multiple channels, the minimal role of military force, and the absence of a hierarchy of issues. Security issues were largely excluded from Sino-Saudi bilateral relations, while economic interests dominated the agendas of the two countries. In the first phase (2001-05), high-level officials continued to play a leading role in bilateral economic relations. They consistently called for the participation of the private sector in expanding Riyadh-Beijing economic ties. The value of Sino-Saudi total trade continued to climb, reaching USD16.1bn in 2005, and the PRC’s oil imports from the KSA reached 22.2 million tonnes in the same year. Some joint investment projects that involved the participation of Chinese and Saudi companies in the hydrocarbons sector were successful. With regard to the construction industry, Chinese companies won four construction projects from the Saudi Arabian cement industry. The second phase (2006-10) was marked by substantial advancement in Sino-Saudi relations. Following the exchange visits of the state leaders in 2006, bilateral contacts expanded rapidly. The visits led to the formulation of more strategies, with the intention of cementing the relationship, increasing contact and concluding more agreements. The Chinese leaders called for “strategic co-operation”, “a friendly and co-operative strategic partnership”, and “strategic friendly relations”, specifically referring to economic co-operation. This second phase saw Sino-Saudi total trade increase to USD 33bn in 2009, and the volume of PRC oil imports from the KSA reached a peak of 41.8million barrels in the same year. With regard to the hydrocarbons joint ventures, in which investments were jointly made by Saudi ARAMCO and Sinopec, the projects in Quanzhou and Rub’ Al-Khali were good examples of the strong co-operation between PRC and KSA companies. The Quanzhou plant launched operation in 2009, and the gas-exploration project in Rub’Al-Khali engaged in drilling for another three years (its operation began in 2004). The achievement of SINOPEC SABIC Tianjin Petrochemical Co., Ltd, as part of the Tianjin petrochemical project, is another example of such co-operation. In non-hydrocarbons joint ventures, mutual investment increased exponentially, particularly in the mining sector.

These chemical systems were composed by surfactant, cosurfactant, oil phase and aqueous phase. In the studied systems, three points in the water -rich microemulsion region of the phase diagrams were used in oil removal experiments. These microemulsion systems were characterized to evaluate the influence of particle size, surface tension, density and viscosity in micellar stability and to understand how the physical properties can influence the oil recovery process. The limestone rock sample was characterized by thermogravimetry, BET area, scanning electron microscopy and X-ray fluorescence. After preparation, the rock was placed in contact with light and heavy oil solutions to allow oil adsorption. The removal tests were performed to evaluate the influence of contact time (1 minute, 30 minutes, 60 minutes and 120 minutes), the concentration of active matter (20, 30 and 40 %), different cosurfactants and different oil phases. For the heavy oil, the best result was on SME 1, with 20 % of active matter, 1 minute of contact time, with efficiency of 93,33 %. For the light oil, also the SME 1, with 20 % of active matter, 120 minutes of contact time, with 62,38 % of efficiency. From the obtained results, it was possible to conclude that microemulsions can be considered as efficient chemical systems for oil removal from limestone formations / O presente trabalho objetivou estudar a remo??o de fra??es de ?leo leve e pesado em rocha calc?ria desintegrada atrav?s de sistemas microemulsionados, comparando as efici?ncias de remo??o em diferentes concentra??es de mat?ria ativa (C/T) e tempo de contato. Os sistemas microemulsionados (SME) s?o constitu?dos por tensoativo, cotensoativo, fase oleosa e fase aquosa. Nos sistemas estudados, tr?s pontos ricos em ?gua da regi?o de microemuls?o foram utilizados para verificar a efici?ncia de remo??o. Os sistemas foram caracterizados para avaliar a influ?ncia do tamanho do agregado, tens?o superficial e viscosidade na estabilidade micelar e compreender como as propriedades f?sicas podem influenciar o processo de remo??o de ?leo. A amostra de rocha calc?ria foi caracterizada por Termogravimetria, ?rea BET, Microscopia Eletr?nica de Varredura, Difra??o de Raios-X e Fluoresc?ncia de Raios-X. A rocha preparada foi colocada em contato com solu??o de ?leo leve e pesado em xileno para permitir a adsor??o de ?leo. Os testes de remo??o foram realizados a fim de avaliar a influ?ncia do tempo de contato (1, 30, 60 e 120 minutos), da concentra??o de mat?ria ativa (20, 30 e 40%), do cotensoativo e da fase oleosa. Para o ?leo pesado, o melhor resultado foi para o SME 1, com 20 % de mat?ria ativa, no tempo de 1 minuto, com 93,33 % de efici?ncia. Para o ?leo leve, o SME 1 no percentual de 20 %, com 120 minutos apresentou o melhor rendimento, com 62,38 %. A partir dos resultados obtidos, concluiu-se que os sistemas microemulsionados apresentam-se como uma alternativa eficaz para remo??o de ?leo em forma??es calc?rias
