The past few decades have seen a veritable explosion of investment treaty and other arbitration claims brought against States. Many of these claims have been heard through ICSID arbitration. In comparison to other arbitration frameworks, the ICSID regime has its own self-contained rules for enforcement. Thus, given the significant increase in arbitration claims against States, on the one hand, and States’ not too seldom invoking of the defence of sovereign immunity, on the other hand, this treatise is timely in addressing various outstanding issues that award-creditors have and will continue to encounter when dealing with defaulting States.   The doctrine of sovereign immunity translates into the conventional wisdom that a State cannot be sued without its consent in foreign courts. This doctrine derives from the practical consequence that the sovereign makes the law, and consequently can break it too. This idea is an extension of primarily the common law doctrine to the international plane, which emerged largely as a result of international comity.[1] This concept is also based upon principles ‘equality’ in terms of ‘equal sovereign status’. Some authors even call it ‘independence’ and ‘dignity’ etc., In this respect, the ICJ has also held that it was equality, that is the basis, i.e. justification for the general rule of immunity.   The theory of immunity has gradually shifted from absolute to restrictive immunity, making it significantly easier for award-creditors to enforce an arbitral award. However, the barrier vis-à-vis immunity from execution makes the last link in ITA vulnerable. This evolution has made substantially an easier task for award-creditors in ITA and ISDS holding an arbitration award against a sovereign State. In view of this relatively at ease syndrome that award-creditors now possess, the immunity protections granted to State and its assets will be accessed albeit the proportionality test of acta jure imperii (i.e. sovereign or government purpose) &amp; acta jure gestionis (i.e. commercial or mixed purpose) and the measurement standard applied to such tests is UNSCI 2004, which are now largely constituting States customary international law.   Ultimately, to the author’s opinion, the value of international arbitration (‘ITA and ISDS’) as a means and ends of solving disputes is dependent upon the extent to which arbitral awards are honoured and enforced. In this light, the author can vociferously say that sovereign immunity remains a significant impediment against award-creditors seeking to enforce arbitral awards against unwilling States. The barrier is not one that will fade away. Thus, outstanding award-creditors could be advised to exercise some pressure through alternate and viable forms of enforcement measures. Therefore, the States should not stand-alone to shield their commercial assets from enforcement, attachment and execution, especially for de minimis sovereign purposes.[2]  [1] R Doak Bishop (ed), Enforcement of Arbitral Awards against Sovereigns (JurisNet, LLC Publ 2009).

The main focus of this thesis is applied research targeting industrial applications of Usage Control (UCON) and policy-based governance. Nonetheless, we also tackle an associated core problem to address the diverse requirements of the targeted application domains. The core research problem is three-fold. (1) UCON enacts usage control in a fixed life cycle of three temporal phases: pre, ongoing and post. However, emerging security paradigms require custom and finer-grained lifecycles with phases and transitions tailored for the application domain. For example, data hub applications entail data-oriented usage control throughout the different stages of the data lifecycle (e.g., collection, retention, processing and destruction). Therefore, policy systems must enable custom lifecycles to accommodate a wide variety of applications. (2) Although UCON allows attribute values to change and updates usage decisions accordingly, it does not specify a mechanism to govern attribute values. This becomes necessary in decentralised environments where attributes are collected from external parties that are not necessarily trusted. For this reason, policy systems must incorporate a mechanism to govern attributes, prepare them for policy evaluation and ensure their trustworthiness. (3) Due to its widespread adoption, UCON has been extended and adapted for diverse purposes, leading to a proliferation of frameworks. While these variations added significant contributions in their respective fields, they lack comprehensiveness and generality. Therefore, a unified solution is needed to encompass the existing variations of UCON as well as future applications. By addressing these core problems, we aim to leverage policy-based governance in the following four industrial applications: (1) Industrial/International Data Spaces (IDS), (2) data hubs, (3) smart vehicles, and (4) credential transformation.To address these challenges and fulfil our applied research goals, we present six contributions in this thesis. (1) We propose UCON+: an extensible model that extends beyond traditional access and usage control providing a comprehensive framework for policy-based governance. UCON+ builds on the same foundations of UCON, making it an attribute-based model that incorporates continuous monitoring and policy re-evaluation. However, it only defines general structures and common functions, and outlines extensible behaviour to be implemented by concrete extensions. Specifically, UCON+ allows concrete extensions to govern attribute values and updates, and to specify custom lifecycles tailored for their respective requirements. (2) We introduce a general-purpose policy engine that implements the UCON+ model. The engine conserves an Attribute-Based Access Control (ABAC) baseline using a standard policy language. The policy engine also introduces another type of policies used to govern attribute values, and to define and drive custom lifecycles. Thus, different extensions of UCON+ can be realised within the same policy engine using policies, eliminating the need for reimplementation. The policy engine leverages a modular architecture with an optimised implementation. (3) We demonstrate the use of the policy engine in a cloud service that provides an IDS for contract-based data exchange. We specifically used the policy engine and designed a custom lifecycle to govern and drive the contract negotiation between the data provider and data consumer using policies. We also used the policy engine to govern data usage based on the negotiated data sharing agreement. (4) We also showcase the policy engine in a data hub setting, where we leveraged it to track and govern data objects throughout their lifecycles. We designed a lifecycle that captures the different stages of the data lifecycle based on the General Data Protection Regulation (GDPR). We show how data usage is controlled at each stage of the lifecycle using policies. (5) We present a dynamic identity management and usage control framework for smart vehicles using the policy engine. We specifically introduce a policy-based Security Token Service (STS) that issues contextualised capabilities that specify what subjects are allowed to do within the vehicle. The STS also manages the capabilities throughout their lifecycles and revokes them if the corresponding policies are violated, while also taking safety measures into consideration. (6) Finally, we describe an application of the policy engine for policy-based credential transformation. Specifically, we introduce a policy-based credential bridge that exchanges, aggregates or maps credentials between different domains or regulatory frameworks. The bridge uses policies that specify how to transform or issue credentials according to the requirements of each domain.

Cette thèse s'intéresse aux questions d'accès aux marchés financiers dans les économies émergentes et en développement. La première partie donne un aperçu général des conséquences macroéconomiques de l'un des régimes de politique monétaire le plus favorable au marché - le ciblage d'inflation - en utilisant le cadre d'analyse de la méta-analyse. La deuxième partie analyse le risque et la stabilité des marchés obligataires des États. La troisième et dernière partie examine les effets disciplinaires résultant de la participation aux marchés obligataires souverains. Plusieurs résultats émergent. Au chapitre 1, les résultats indiquent que la littérature sur les effets macroéconomiques du ciblage d'inflation est sujette à des biais de publication. Après avoir purgé ces biais, le véritable effet du ciblage d'inflation reste statistiquement et économiquement significatif à la fois sur le niveau de l'inflation et la volatilité de la croissance économique, mais ne l’est pas sur la volatilité de l'inflation ou le taux de croissance économique réel. Aussi, les caractéristiques des études déterminent l’hétérogénéité des résultats de l'impact du ciblage d’inflation dans les études primaires. Le chapitre 2 montre que l'adoption d'un régime de ciblage d'inflation réduit le risque souverain dans les pays émergents. Cependant, cet effet varie systématiquement en fonction du cycle économique, de la politique budgétaire suivie, du niveau de développement et de la durée dans le ciblage. Le chapitre 3 montre que les envois de fonds des migrants, contrairement aux flux d'aide au développement, permettent de réduire le risque souverain. Cette réduction est plus marquée dans un pays avec un système financier moins développé, un degré d'ouverture commerciale élevé, un espace budgétaire faible et sans effet dans les pays dépendants des envois de fonds. Le chapitre 4 montre que les pays ayant des contrats d’échange sur risque de crédit sur leurs dettes sont plus sujets à des crises de dette. Il constate également que cet effet reste sensible aux caractéristiques structurelles des pays. Le chapitre 5 montre que la participation aux marchés obligataires de long terme (domestiques et internationaux) encourage les gouvernements des pays en développement à accroître leurs recettes fiscales intérieures. Il révèle également que l'effet favorable dépend du niveau des recettes de seigneuriage, d’endettement, du régime de change, du niveau de développement économique, du degré d’ouverture financière, et du développement financier. Le chapitre 6 montre que la présence de marchés obligataires domestiques, de long terme et liquides réduit considérablement le degré de dollarisation financière dans les pays en développement. Cet effet est plus important dans les pays avec un régime monétaire de ciblage d’inflation ou de change flottant, et à règles budgétaires. Enfin, il constate que la présence de marchés obligataires domestiques réduit la dollarisation financière à travers la baisse du niveau et de la variabilité de l'inflation, de la variabilité du taux de change nominal, et des revenus de seigneuriage. / This thesis focuses on some critical issues of the access to international financial markets in developing and emerging market economies. The first part provides a general overview of the macroeconomic consequences of one of the most market-friendly monetary policy regime—inflation targeting—using a meta-regression analysis framework. The second part analyses government bond market risk and stability. The last part investigates the disciplining effects of government bond market participation—bond vigilantes. In Chapter 1, the results indicate that the literature of the macroeconomic effects of inflation targeting adoption is subject to publication bias. After purging the publication bias, the true effect of inflation targeting appears to be statistically and economically meaningful both on the level of inflation and the volatility of economic growth, but not statistically significant on inflation volatility or real GDP growth. Third, differences in the impact of inflation targeting found in primary studies can be explained by differences in studies characteristics including the sample characteristics, the empirical identification strategies, the choice of the control variables, inflation targeting implementation parameters, as well as the study period and some parameters related to the publication process. Chapter 2 shows that the adoption of inflation targeting regime reduces sovereign debt risk in emerging countries. However, this relative advantage of inflation targeting—compared to money or exchange rate targeting—varies systematically depending on the business cycle, the fiscal policy stance, the level of development, and the duration of countries’ experience with inflation targeting. Chapter 3 shows that remittances inflows significantly reduce bond spreads, whereas development aid does not. It also highlights that the effect of remittances on spreads arises in a regimes of lower developed financial system, higher degree of trade openness, lower fiscal space, and exclusively in non-remittances dependent regimes. Chapter 4 indicates that countries with credit default swaps contracts on their debts have a higher probability of experiencing a debt crisis, compared to countries without credit default swaps contracts. It also finds that the impact of credit default swaps initiation is sensitive to several structural characteristics including the level of economic development, the country creditworthiness at the timing of credit default swaps introduction, the public sector transparency, the central bank independence; and to the duration of countries’ experiences with credit default swaps transactions. Chapter 5 shows that bond markets participation encourages government in developing countries to increase their domestic tax revenue mobilization. Finally, it finds that bond markets participation improves the mobilization of internal taxes, compared to tax on international trade, and reduces their instability. Chapter 6 shows that the presence of domestic bond markets significantly reduces financial dollarization in domestic bond markets countries. This effect is larger for inflation targeting countries compared to non-inflation targeting countries, is apparent exclusively in a non-pegged exchange rate regime, and is larger when there is a fiscal rule that constrains the conduct of fiscal policy. Finally, it finds that the induced drop in inflation rate and its variability, nominal exchange rate variability, and seigniorage revenue are potential transmission mechanisms through which the presence of domestic bond markets reduces financial dollarization in domestic bond markets countries.

Derived from a marxist/liberal humanist view of power, conventional critiques and historical accounts of the socio-medical sciences in South Africa see only their power to repress and negate the true bodily attributes and authentic person of the African. In so doing, they ignore the productive capacity of these knowledges and practices as a manifestation of what Michel Foucault termed "disciplinary" power, by which the human body is manufactured and made manageable as an object of medical knowledge and industrial utilisation. Accordingly, this thesis offers just such a Foucaultian reading of western socio-medical knowledge in South Africa to demonstrate how it has operated to fabricate the bodies of Africans as visible objects possessed of distinct attributes that have provoked particular strategies for their surveillance, management, and government in health and disease. / Psychology / D.

In July 2014, Argentina entered selective default, even as the country remained financially solvent. The default stemmed not from economic woes, but rather from protracted international litigation between Argentina and a group of hedge funds who, for years, refused to negotiate with Argentina over their bond holdings in the wake of the country’s first default in 2001. These holdouts stalled negotiations and locked Argentina out of international credit markets, damaging the country’s economy and financially harming other creditors and Argentinian citizens alike. Argentina ended up in such a dilemma because of the current sovereign debt restructuring process. No international arbitrator of sovereign debt currently exists. Instead, a country must negotiate with creditors on an ad-hoc basis, gathering support from 100% of creditors before it can restructure its debt and reenter international credit markets, an extremely inefficient system. This paper will assess the current system of sovereign default renegotiations, identifying inefficiencies in the current system, reviewing past proposals for improvements to the system, and ultimately proposing an international arbitrator for default negotiations. This text uses the development of the US Federal Municipal Bankruptcy Act of 1934 as a guide for an international bankruptcy court. Prior to the passage of the law, municipalities faced many of the same challenges faced by defaulted nations today, including powerful holdouts and a lack of structure in the negotiation system. Given the similarities between the two cases, the Federal Municipal Bankruptcy Act serves as an ideal framework for sovereign default arbitration internationally.

Despite their natural resources, the countries of the Gulf Cooperation Council (Kuwait, the United Arab Emirates, Saudi Arabia, Bahrain, Qatar, and Oman) have failed to live up to their economic potential, primarily due to their dependence on a revenue source with volatile prices and political significance in an unstable region. This thesis argues that the best way to convert oil wealth into consistent long term growth is through diversification, both by investing in foreign assets and by growing domestic sectors that are independent from oil and gas prices. The research further investigates the primary tool these countries have used to do so – sovereign wealth funds – and how their implementation and structures have impacted their effectiveness in achieving economic diversification and growth.

This thesis considers how fiscal and monetary policy should be conducted in resourcerich economies. It consists of three papers addressing: whether governments should spend, save or invest volatile oil income; the assets they should save in; and how monetary policy should respond. The first, “Eight principles for managing resource wealth”, shows that capital-scarce countries should save relatively less against oil price volatility, and invest more in domestic capital. They also should prepare for volatility in advance, and treat savings as a source of income rather than a temporary buffer. To show this the paper develops a framework that nests a variety of existing results, which are presented in eight principles. The second, “The Elephant in the Ground: Oil extraction and asset allocation in sovereign wealth funds”, shows that governments should use sovereign wealth funds to offset oil price risk, extract oil faster if its price is pro-cyclical, and use precautionary savings to manage any residual volatility. To do this it combines three strands of literature for the first time: on continuous-time portfolio theory, oil extraction and precautionary savings. The third, “Optimal monetary responses to oil discoveries”, addresses the anticipation effects around an oil discovery. It shows that the terms of trade will need to appreciate twice: once when oil is discovered and consumers anticipate future revenues; and again when the government begins spending the revenues. Oil wealth will give the monetary authority an incentive to appreciate the terms of trade, in addition to stabilising domestic inflation and the output gap. Optimal policy is well-approximated by a standard monetary rule that also responds to expected changes in the natural level of output.

How can political science account for the decision of African states to strengthen their ties with China, often at the expense of other alliances and often in the face of economic risks? This thesis explores this question in the context of relations between Ethiopia and China, especially in the context of investments made by Chinese sovereign wealth funds in the Ethiopian economy. To begin to answer this question this thesis recasts the China-Africa debate to focus on African, i.e. Ethiopian, agency. The focus is on how Ethiopia's political leaders make foreign policy decisions and on the factors that shape their preferences. This focus reveals the influence of cognitive variables on their foreign policy decisions; the influence of their guiding ideology, 'revolutionary democracy,' is especially key. An analysis of Ethiopia's formal institutions demonstrates they are inadequate to explain the policy choices of Ethiopian leaders; they have been designed to reflect the concepts of revolutionary democracy. Using the language of prospect theory, a descriptive theory of decision-making under risk, this thesis contends that Ethiopian leaders select foreign policy options by weighing their possible outcomes as gains or losses relative to revolutionary democracy as their reference frame. Ethiopian leaders sanctioned China's finance of the Ethiopian Telecommunications Corporation despite the monopoly it gave to China and its impact on Ethiopia's debt. They formed a front company between Ethiopia and China's military industrial complexes despite its negative effects on economic development. They opened Ethiopia’s regions to Chinese capital although capital flows only to state-owned enterprises. Yet in each case, ideological objectives were advanced. This examination demonstrates how non-structural factors play a critical role in a bureaucratized state. Theoretical frameworks that account for these factors, like prospect theory, are therefore valuable to more robust understandings of Ethiopia, and Africa's, deepening relations with China.

L’intérêt principal de l’analyse du cadre des investissements miniers et pétroliers chinois en Afrique est la détermination du chantier juridique résultant de la cohabitation de deux cultures juridiques en vue de l’émergence d’une lex mercatoria dans les investissements sino-africains. Elle comprend deux parties principales. D’abord, l’étude se penche sur l’origine des fonds chinois investis sur le continent africain qui sont les fonds souverains. La problématique des fonds souverains est celle de savoir s’il s’agit d’instruments politiques ou financiers. Néanmoins, cette inquiétude ne freine pas la force opérationnelle grandissante des fonds souverains chinois sur le continent africain. Rentrant dans l’encadrement et le contenu du contrat proprement dit, l’analyse des figures contractuelles usitées dans l’industrie pétrolière et minière sino-africaine séparément dans les contextes chinois et africains révèle l’inadéquation des contrats et de la législation africaine aux besoins économiques et technologiques du continent. En outre, l’examen particulier des clauses de choix de la loi applicable et de règlement des différends dans les contextes chinois et africain permet de soulever quelques options possibles pour le contexte sino-africain. Ensuite, l’analyse se penche sur les mécanismes mis en place pour favoriser les investissements chinois miniers et pétroliers sur le continent africain avant de relever les conséquences dans les domaines sociaux et environnementaux desdits investissements. Il ressort donc que des avantages fiscaux et douaniers sont mis en place en faveur des investissements chinois en Afrique ainsi que des traités bilatéraux signés entre la Chine et de nombreux pays africains. Cependant, sur le plan social, l’on s’interroge sur la place accordée à la lutte contre la corruption et la promotion de la transparence dans l’industrie extractive africaine avec ses relations avec la Chine. L’on constate également que l’absence de transfert de technologie influe négativement sur le développement économique et technologique, la concurrence et l’emploi local du pays hôte. De même, la protection de l’environnement dans le contexte sino-africain semble être reléguée au dernier plan. L’environnement africain court donc le risque de connaître une crise comme celle de la chine causée par l’industrialisation du pays. La société civile nous apparaît donc au regard de ces effets peu glorieux des investissements chinois en Afrique dans les domaines miniers et pétroliers comme une troisième partie de cette relation qui devra être la médiatrice ou régulatrice entre les deux autres. / The main objective of this analysis is to determine the juridical patterns of the Chinese and African legal cultures cohabitations, in order to pursue a Chinese-African lex mercatoria. The survey of Chinese mines and oil investments in Africa will be done in two principal parts. First, the study goes over the origin of the Chinese funds invested in Africa. Sovereign wealth funds in general causes questioning concerning their real purpose: are they financial or political instruments? Nevertheless, it is still obvious that this questioning does not stop Chinese sovereign wealth funds to continue to expand all over Africa. Also, going into the contracts and the legislation itself, the analysis of the contractual figures used in the mining and oil extractive industry individually in the Chinese and African context reveals the African contracts and legislation is not adequate to the continent’s economical and technological needs. Continuing into the particular analysis of the applicable law and the arbitration clauses in the Chinese and African context individually, it was possible to outpoint some options to the Chinese-African context. Secondly, the survey points out the mechanisms enabling Chinese investment into Africa and the consequences of these investments in the economical, social and environmental context. It was then pointed out that fiscal and customs mechanisms and also bilateral investment treaties signed in between China and numerous African countries favors Chinese investments in Africa. Still, the main social impact reveals some interrogations concerning the fight against corruption and promotion of transparency in Africa. Is the Chinese partnership considerate of this aspect? Moreover, the lack of technology transfer gets to negatively influence local competition and employment as well as economical and technological development. Also, environmental protection in the Chinese-African context seems to me sent far behind. Therefore, the African environment risks to face an environmental crisis just like China did because of the country’s industrialization. Civil society here, considering these less attractive impacts of Chinese investment in oil and mining sectors in Africa, appears to be a very useful third party with the role of mediation and regulation between the two others.
