This study investigates the influence of Marshallian neo-classical economics on management accounting in South Africa and considers the impact this might have on the relevance of the subject. The investigation finds that whilst emerging management accounting theory is not based on Marshallian neo-classical economics, more traditional perspectives are. This observation results from a review of literature in the English-speaking world. Management accounting practice in South Africa appears to be based on Marshallian neo-classical economics. This conclusion is drawn from empirical work undertaken amongst management accounting practitioners from companies listed on the Johannesburg Stock Exchange. The inquiry indicates that South African management accounting education is based on Marshallian neo-classical economics. This finding emerges from an analysis of the textbooks and syllabi prescribed by South African education institutions. The investigation into the nature of Marshallian neo-classical economics reveals its shortcomings as a basis for management accounting practice. This form of economics accepts premises of limited government intervention and much free competition in the market, and assumes that decision-makers are rational, utility maximising individuals with access to perfect and freely available information. The focus of Marshallian neo-classical economics is limited. It disregards social, cultural and historical circumstances and restricts decisions to a moment in time. Such assumptions are unrealistic and cannot be used as a basis for a subject that aims to provide relevant information for decision makers in today’s business environment. / Thesis (DCom (Financial Management))--University of Pretoria, 2007. / Financial Management / unrestricted

This thesis attempts to throw light on the underlying reasons behind the economic ambivalence between EU countries. In this sense, Greece and Sweden will be posted at the center of my research interest. For this purpose, Intersectionality theory as well as Neo liberalism and Neoclassical economics will be used in such a way that will assist me to disclose the deep causes of this inequality and to further examine how intersections of gender, age/generation and class are intertwined and affect the youth and elderly in both countries. Furthermore, both qualitative and quantitative data will be applied in a way that will enable me to compare and contrast the two social groups chosen. Having demonstrated that, I will move a step forward by narrowing down my research focus on how the youth in both countries react against this kind of social exclusion.

Cette thèse prend pour objet les transformations de l’analyse macroéconomique aux États-Unis durant les années 1970 tout en questionnant la manière d’étudier et d’analyser ces transformations. Du point de vue de l’histoire des faits, la période semble marquer une rupture par rapport à la relative stabilité économique de l’après-guerre. Cette période d’instabilité économique, qu’on nomme stagflation, fait écho à l’instabilité de la théorie macroéconomique aux États-Unis. Le consensus de l’époque, considéré comme « keynésien », se retrouve attaqué par les économistes dits « monétaristes » et « nouveaux classiques ». Le dernier des groupes cités est celui des « révolutionnaires », celui dont on considère qu’il a changé radicalement la discipline. Le but de ma thèse est d’étudier l’influence des nouveaux classiques sur la macroéconomie dans les années 1970 en mobilisant un appareil historiographique qui met au cœur de l’étude le rôle joué par la stagflation, et de confronter les résultats de cette étude avec l’histoire « conventionnelle » de la macroéconomie. La thèse s’articule autour de quatre articles indépendants les uns des autres. Le premier chapitre propose une comparaison entre les méthodologies de Lucas et Sargent, et montre que le second tente de donner un caractère plus réaliste aux modèles de la Nouvelle Économie Classique, en utilisant les anticipations rationnelles pour décrire différents phénomènes économiques. Le second chapitre prend pour objet la confrontation entre Lucas et Sargent d’un côté, et les défenseurs des modèles macroéconométriques structurels de l’autre. Le chapitre 3 étudie l’évolution des travaux de Robert Gordon sur l’inflation dans les années 1970 et documente la manière dont celui-ci adopte petit à petit l’hypothèse de taux de chômage naturel. Le chapitre 4 enfin s’intéresse aux débats empiriques au début des années 1980, autour de la crise de Lucas. / This thesis focuses on the transformations of macroeconomics in the United States during the 1970s, while questioning the way to study and to analyze these transformations. From the point of view of economic history, the period seems to mark a break with the relative stability post World War II years. This period of economic stability, that one calls “stagflation”, echoes the instability of U.S. macroeconomic theory. The consensus of the time, regarded as “Keynesian”, is attacked by economists labeled as “Monetarist” and “New Classical”. The last group is the one of “revolutionaries”, regarding as having radically transformed the discipline, as the Copernican revolution overthrown the geocentric representation of the universe. My goal in the thesis is to study the influence of New Classical economists on macroeconomics in the 1970s, by appealing to an historiographical framework which outs at the heart the role played by stagflation, and by confronting the results of this work to the standard narrative. This thesis is built around four articles, independent from one another. The first chapter proposes a comparison between the methodologies of Lucas and Sargent, and shows how the latter intend to give a more realistic character to the new classical economy models, by using rational expectations to describe different economic phenomena. The second chapter takes interest in the confrontation between Lucas and Sargent on one side, and the defenders of structural econometric models on the other. The third chapter studies the evolution in the works of Robert Gordon on inflation in the 1970s, and documents the way he gradually adopts the natural rate of unemployment hypothesis. Finally, the chapter four is interested in the empirical debates in the early 1980s, about the Lucas critique.

NFTs (Non-Fungible Tokens) are digital assets representing real-world objects like art, music, videos, gaming items, etc., originally, they reside on a blockchain indicating a certificate of authenticity or proof of ownership deeming the uniqueness and scarcity of commodities. They have shown astonishing market attention and inconceivable price margins are being set for certain NFTs. The NFT phenomenon being in a nascent state, not much research has been conducted from the standpoint of value from the users and this thesis tries to fill the gaps in that area from a socio-economic point of view. The use of NFTs is on a rise with several companies delving in and speculated to grow even bigger bringing a transformative shift in the way businesses work today, using the blockchain technology NFTs are heralded as a new way to define ownership and property constructs. Going forward it is expected that they could be a gateway to a tokenised future through a new form of value assessment of commodities and transitioning economic functions. This dissertation ventures on to look at the value perspective from the masses on how they shape an individual's viewpoint. Through a classical economic intervention of theories as discoursed in the literature review, this research tries to infer nuances of users employing a qualitative study whereby unstructured interviews were the source for data collection and using a thematic analysis various themes are derived which are pointed out in the discussion section. The analysis gives us an indication that many people are indulged in the NFT space as a source of profit maximisation and several indications are portrayed towards community building as a means of value creation. The qualitative nature of the study relies on interpretivism and a radical structuralist paradigm shedding light on the thought process behind an individual’s behaviour, trying to understand the context of ‘value’ as perceived by the people.

Ce travail propose une mise en perspective des pratiques de modélisation macroéconomique,depuis les travaux de Robert E. Lucas dans les années 1970 jusqu’aux contributions actuelles de l’approche dite d’équilibre général dynamique stochastique (DSGE). Cette mise en perspective permet de caractériser l’essor des modèles DSGE comme un compromis entre conceptions antagonistes de la modélisation : d’une part, celle de l’approche des cycles réels (RBC) et, d’autre part, celle de la nouvelle économie keynésienne. Pour justifier cette opposition, ce travail propose une reconstruction épistémologique de l’histoire récente de la macroéconomie, à savoir une analyse des différents critères qui définissent la validité et la pertinence d’un modèle. L’hypothèse de travail est qu’on peut identifier, pour chaque pratique de modélisation,trois critères méthodologiques fondamentaux : la validité interne (l’adéquation des hypothèses d’un modèle aux concepts aux formalismes d’une théorie), la validité externe(l’adéquation des hypothèses et/ou des résultats d’un modèle au monde réel, et les procédés quantitatifs pour évaluer cette adéquation) et le critère de hiérarchie (la préférence pour la validité interne sur la validité externe, ou vice versa). Cette grille de lecture, inspirée de la littérature sur les modèles en philosophie des sciences, permet d’apporter quatre contributions originales à l’histoire de la macroéconomie récente. (1) Elle permet de concevoir l’essor des modèles DSGE sans faire appel à l’explication proposée par l’historiographie produite par les macroéconomistes eux-mêmes,à savoir l’existence d’un consensus et d’un progrès technique exogène. Contre cette vision de l’histoire en termes de progrès scientifique, nous mettons en avant les oppositions méthodologiques au sein de la macroéconomie et nous illustrons l’interdépendance entre activité théorique et développement des méthodes statistiques et économétriques. (2) La thèse s’attaque au cloisonnement entre histoire des théories macroéconomiques et histoire des méthodes quantitatives. Grâce à sa perspective méthodologique, ce travail permet d’opérer la jonction entre ces deux littératures et de développer les bases d’une vision globale des transformations récentes de la macroéconomie. (3) La relecture méthodologique de l’histoire de la modélisation permet de mettre en évidence comment la condition de validité externe a représenté le principal point de clivage entre différentes conceptions de la modélisation. La question de la validité externe apparaît par ailleurs intrinsèquement liée à la question de l’explication causale des phénomènes, sur laquelle repose largement la justification de la modélisation comme outil d’expertise des politiques économiques. (4) Ce travail aboutit à une caractérisation originale de l’approche DSGE : loin de constituer une «synthèse» ou un consensus, cette approche s’apparente à un compromis, fragilisé par l’antagonisme méthodologique entre ses parties prenantes. / This dissertation provides a history of macroeconomic modeling practices from RobertE. Lucas’s works in the 1970s up to today’s dynamic stochastic general equilibrium (DSGE) approach. Working from a historical perspective, I suggest that the recent rise of DSGE models should be characterized as a compromise between opposing views of modeling methodology—on the one hand, the real business cycle (RBC) view, on the other hand, the new Keynesian view. In order to justify this claim, my work provides an epistemological reconstruction of the recent history of macroeconomics, building from ananalysis of the criteria defining the validity and the pertinence of a model. My assumption is that recent macroeconomic modeling practices can be described by three distinctive methodological criteria : the internal validity criterion (which establishes the consistency between models’ assumptions and concepts and formalisms of a theory), the external validity criterion (which establishes the consistency between the assumptions and results of a model and the real world, as well as the quantitative methods needed to assess such a consistency) and the hierarchization criterion (which establishes the preference for internal over external validity, or vice versa). This epistemological reconstruction draws primarily from the literature about models in the philosophy of science. My work aims to make four contributions to the history of recent macroeconomics. (1) To understand the rise of DSGE models without referring to the explanation providedby the macroeconomists themselves, who tend to think that macroeconomics evolved through theoretical consensus and exogenous technical progress. By distancing itself fromthis perspective, my work draws attention to the disruptive character of methodological controversies and to the interdependence between theoretical activity and the developmentof statistical and econometric methods. (2) To overcome the existing divide betweenthe history of macroeconomic theories and the history of quantitative methods. Throughits epistemological perspective, my work reconciles these two historiographies and specifiesthe basis for a comprehensive understanding of recent developments in macroeconomics.(3) To put the accent on the external validity condition as the main controversial issue separating different views of macro-modeling methodology. Furthermore, I illustrate how the debate about external validity is closely related to the problem of casual explanation and, finally, to the conditions for providing economic policy evaluation. (4) To characterize the DSGE approach: although DSGE models are often presented as a“synthesis”, or as a “consensus”, they are better described as a shaky compromise between two opposing methodological visions.

The main aim of this presented diploma thesis is to help build a systematic understanding of the political and social foundations of global financial markets, their operations and impacts on the global power affairs. The thesis highlights the dynamic complexity of the post financial crisis state of the World with its itra- and inter-social features. It instrumentaly uses critique of a free market agenda and neo-classical economy which contrasts the Efficient Markets Hypothesis with Hyman Minsky's Financial Instability Hypothesis (FIH), taking into account the dynamic complexity of financial markets. This approach offers analytical tools that can account for crisis through processes endogenous to contemporary financial capitalism. I shall argue that a financially complex system is, according to the FIH, inherently flawed and unstable. After a theoretical and historical review, the thesis discusses various aspects of the process of austerity regime and its social consequences. This provides an opportunity for analyses of the ongoing existence of interstate competition, of militarised foreign policy, and of other international, at times violent conflicts. In an effort to make sense of some of these phenomena, I instrumentaly use the study of geoeconomics that builds on some fundamental assumptions...
