La thèse étudie la compétitivité-coûts et hors-coûts de la chine et ses impacts sur le reste du monde entre 1970 et 2012. Au début, la performance commerciale de la Chine s’appuyait sur la compétitivité-coûts. Depuis les années 1990, son avantage-coûts a diminué, surtout comparée à la Thaïlande et à l’Inde. Par ailleurs, son avantage hors-coûts, mesuré par le changement structurel, a été accompagné par une augmentation de la contribution des inputs importés à l’exportation.. Ceci indique premièrement que la dépendance chinoise vis-à-vis du reste du monde a augmenté et, deuxièmement, que l’exportation chinoise a entrainé plus d’exportation du reste du monde qu’auparavant. Parmi ces exportateurs, les pays asiatiques sont toujours les plus grand bénéficiaires de cette expansion des exportations chinoises. / This thesis studies the cost- and non-cost competitiveness of China and its impacts on the rest of the world between 1970 and 2012. At outset, Chinese commercial performance was gradually enhanced by its cost-competitiveness. Since 1990s, China has lost the cost advantage, especially compared with Thailand and India. Furthermore, Chinese non-cost advantage, based on structural change of export, has relied on the rise of imported inputs. It implies that firstly the dependence of Chinese exports on other countries has increased and, secondly, Chinese exports have progressively induced more exports of the rest of the world than before. Asian countries have been the largest beneficiaries of Chinese export expansion.

The thesis complexly assesses the role of Germany in present European Union and Eurozone, especially its influence and responsibility on the formation of the macroeconomic imbalances before the Eurozone crisis, as well as its resolution. The crisis is caused by a divergence in unit labour costs between member countries, and the thesis aims to evaluate the effect of applied austerity measures in the debtor countries on the adjustment of said unit labour costs divergence. It explores additional policy options available as well.

Cette thèse examine le rôle du système social et fiscal sur la distribution des revenus, en mettant l'accent sur les revenus du travail.La première partie de la thèse présente la méthodologie et les résultats d'un modèle de microsimulation des prélèvements et transferts français. Le premier chapitre offre une description complète de la répartition des recettes fiscales en fonction de la distribution des revenus. Le deuxième chapitre analyse l'impact macro et micro-économique des réponses politiques à la crise de 2008 en France.La deuxième partie de la thèse porte sur l’imposition des revenus du travail. Les questions et les méthodes abordées se situent à l'intersection des finances publiques et de la littérature sur l'économie du travail. Le premier chapitre étudie l’ensemble de la distribution des salaires, en insistant sur le rôle des cotisations de sécurité sociale pour l'évolution de l'inégalité. Le dernier chapitre se penche sur l'impact d'une taxe sur les salaires au sommet de la distribution (0,003%, environ 1 500 personnes) sur le processus de fixation des salaires des plus riches. / This thesis examines the role of the tax-and-benefit system on the income distribution, with a focus on labour incomes. Made of two parts, the thesis tackles three central questions for the economics of labour and taxation. The first question relates to the simple description of the distributional impacts of taxes. Second, economic actors paying the real cost of taxes might not be the ones paying it legally: assessing empirically the incidence of taxation is key for identifying their distributive implication. Third, the description of the distributional effects of taxes is further complicated by the fact that taxes affect behaviours. In particular, high income individuals may react more to taxes than the rest of the population. This distinction between the very top and the rest of the income distribution is the third major pivotal question of the dissertation.The first part of the thesis presents the methodology and the results of a microsimulation model of the French tax-and-benefit system. The first chapter offers a comprehensive description of the distribution of tax revenues according to the distribution of income. The second chapter proposes an evaluation of the main policy reforms taken in the aftermath of the 2008 financial crisis. It is based on a dual approach, encompassing both a macro and a micro analysis.The second part of the thesis focuses on the taxation process of labour incomes. The questions and the methods tackled are at the intersection of the public finance and the labour economics literature. The first chapter studies the overall wage distribution, emphasizing the role of social security contributions in the evolution of inequality. The last chapter looks at the impact of a wage tax at the very top of the distribution (top 0.003%, about 1500 individuals) on the wage setting process of top labour income earners. A quasi-experimental variation, the 75% tax on millionaires implemented in 2013 and 2014, and evaluation of public policies methods (difference-in-difference method) are used to document the incidence of the tax and the behavioural responses.

I den här uppsatsen studerade vi förhållandet mellan enhetsarbetskostnaden och inflationen bland OECD-länderna. Den metod som vi använde var dels en regression av paneldata med fixed effects och dels en dynamisk modell där vi försökte urskilja det fördröjda förhållandet mellan våra intressevariabler. Förhållandet har länge debatterats och flera teorier har hävdat dess samband men empiriska studier har visat på dess motsats. Vi ville därför bidra till den tidigare forskningen genom att undersöka förhållandet mellan de båda variablerna med ett större antal länder än vad majoriteten av de tidigare studierna har undersökt, men också med mer modern data. Dessutom undersökte vi om förhållandet har försvagats över tid. För att göra detta delade vi upp våra data i två delar, en mellan 1995–2008 och en mellan 2009–2020. Den sista forskningsfrågan vi undersökte är att vi försökte se om förhållandet skiljer sig åt mellan USA och de EU-länder som är medlemmar i OECD. Uppsatsen är uppdelad i ett teoriavsnitt följt av den metod vi använder. Därefter följer ett avsnitt om resultat och analys. Till sist följer en kort sammanfattning. I uppsatsen finner vi stöd för att enhetsarbetskostnaderna har en betydande inverkan på inflationen och vice versa, vilket bekräftar Blanchards teori om att det finns en löne-prisspiral. Vi kan också se att den första eftersläpningen av inflationen har en signifikant inverkan endast när vi inte inkluderar våra kontrollvariabler. När vi vände på regressionen och studerade den första laggen av enhetsarbetskostnaderna ser vi att den har en svagt signifikant inverkan på inflationen, skild från noll. Vidare finner vi skillnader med avseende på uppdelningen i tiden. Våra resultat visar att effekten mellan våra variabler skiljer sig åt mellan 1995–2008 och 2009–2020. Vår tredje och sista forskningsfråga är om förhållandet skiljer sig åt mellan olika geografiska områden. Här fann vi att det finns en signifikant skillnad mellan USA och EU-länderna.

The subject of this work is the approximation and explanation of methods of evaluation of economic variables using indicators and their systems. The thesis also uses a method of a multi-parametric comparison of the indicators. In the thesis are described the individual indicators, then the methods of their evaluation and the creation of the multi-parametric comparison. The thesis deals also with the harmonization of economic statistics and the definition of the assessed area. For practical use, indicators are then selected: Gross Domestic Product, Labor Productivity, Unit Costs, Unemployment Rate, Real Effective Rates, R & D expediture and Human Resources in Science and Technology. Selected indicators are evaluated from a time and space point of view. Furthermore, a method of the multi-parametric comparison was performed for these four indicators: GDP per capita, unemployment rate, R & D expenditure and unit labor costs. The analysis of the indicators shows that currently the economies of all selected countries are growing. Despite the EU's similarity efforts, there are major differences between economies. The great potential for further economic development is technological progress. The way states deals with this opportunity, it can decide on their future development.

MSCAGR (Agricultural Economics) / Department of Agricultural Economics / This research aimed to assess the profitability of sweet potato production enterprises. The focus areas were on: determining differences in profitability of different sweet potato enterprises located in different villages; identifying factors that affect the profitability of sweet potato enterprises; determining differences in the sweet potato markets; and identifying marketing channels utilised by sweet potato enterprises. The study was carried out in 8 villages in Makhado and Thulamela local municipalities of the Vhembe district of Limpopo province. There were 78 sweet potato farmers identified and interviewed as respondents in the study. A gross margin analysis model was used to calculate the profitability of sweet potato enterprises, while a multiple regression model was adopted to analyse factors that affect profitability of sweet potato enterprises. The study revealed the domination of females in sweet potato production, wherein 69.2% of the respondents were females. Furthermore, the study revealed that 16.7% of the respondents were illiterate, 24% of the respondents had never received any form of agricultural training. The findings of the study revealed that sweet potato production is a viable and profitable enterprise in the study area. Farmers recorded an average gross margin of R11 329.94 per ha. Furthermore, labour cost and fertilizer cost accounted for the highest costs incurred in production contributing 45% and 32% respectively to total costs. The results of the study further revealed that six variables were statistically significant to profitability. Occupation status, farming experience, unpaid family members, and labour cost were statistically significant to profitability at the 1% level of significance; whereas tractor hire cost and chemical cost were statistically significant to profitability at the 5% level of significance. The study recommends that stakeholders involved in agriculture and community development should attend to issues such agro-processing trainings and extension services offered to the farmers in the Vhembe district.

This study investigated the determinants of inflation in South Africa using quarterly data from 1970Q1 to 2015Q4. The study was motivated by recent trends in domestic inflation that has frequently been at the upper end of the target range of between 3% and 6% and the need to guide inflation related policy since 2008. These recent trends raised concerns regarding the effectiveness of the current monetary policy approach in responding to internal and external factors that are significant in determining domestic inflation. Using Error Correction Model (ECM) modelling techniques, empirical results revealed that inflation expectations, labour costs, government expenditure and import prices are positive determinants, while GDP and exchange rates are negative determinants of inflation. To achieve the macroeconomic policy objective of a stable and low inflation rate for South Africa, more emphasis should be placed on anchoring inflation expectations, which was found to be highly significant in determining inflation. / Economics / M.
