This essay in economic geography describes what intra-firm trade as a concept is and different ways to determine in which cases trade is to be labeled as intra-firm trade (IFT) or not. The method used by the author is most easily described as descriptive. This method was chosen in order to test if existing theories; classic and neoclassic economics, new trade theory and international business studies, are capable to explain the phenomena of IFT. The theories are tested trough primary and secondary literature but also trough reasoning by the author. The conclusion is that the most reasonable way to determine whether trade occurs intra-firm or not, is to decide upon a 5-% rule where it when one part owns 5-% of the voting strength in the other company is to be considered intra-firm trade. This is a conclusion based on several reasons; the strongest one being that a common view on IFT could boost comparative studies as the U.S already collects data based on the 5-% rule. Classic and neoclassic economics are incapable of explaining IFT as aprerequisite for these theories is that markets are perfect. IFT can only beexplained by models building on imperfect markets hence new trade theory and international business are more successful in explaining IFT.

O objetivo desta tese é analisar a economia política dos acordos preferenciais de comércio (APC) a partir de um jogo político seqüencial não-cooperativo de Stackelberg entre uma grande economia e uma pequena economia, onde a disputa política entre grupos lobistas rivais define as preferências unilaterais dos governos no primeiro estágio e o equilíbrio coalitionproof de Stackelberg define o formato do acordo de livre comércio no segundo estágio. Então se modifica a estrutura inicial do jogo político bilateral para um processo de barganha entre n países. Finalmente, aplica-se o modelo teórico ao caso particular da ALCA. / The purpose of this paper is to analyse the political economy of preferential trade agreements (PTA) based on a sequential non-cooperative Stackelberg political game between a large economy and a small economy, in which the political dispute of rival lobby groups defines the unilateral stance of both governments in the first stage and the Stackelberg coalition-proof equilibrium defines the format of the free trade agreement in the second stage. Then the initial bilateral political game hypothesis is relaxed to accomplish a more complex bargaining game with n economies. Finally the theoretical framework is applied to FTAA.

Trade structure changes over time as a result of fundamental changes within the country or the world around it. This thesis will investigate the case of Czech Republic in the period from the transition period till today with the foundation in classical and neoclassical trade theory. The trade structure will be analyzed in regard to trade partners, commodity structure, relative comparative advantages and degree of intra-industry trade within an industry or sector. It will provide basis for assessing the effects of increased European integration which the Czech Republic increasingly engaged itself in with the accession to the EU in 2004.

The primary objective of this study was to examine how and to what extent entrepreneurial orientation, firm internal resources and capital structure decisions affect growth of small enterprises, following the resource- based view on determinants of growth and static trade-off theory of capital structure as theoretical frameworks. Regardless of the number of earlier study, there is no consensus among scholars on determinants of growth due to the existence of different theories and metrics of growth. Moreover, as the earlier studies were undertaken in developed countries, their research findings could not permit generalization on the effect of the explanatory variables on growth in less developed countries like Ethiopia. Therefore, this research tried to fill the gap in the existing body of knowledge on determinants of growth by contextualizing the association of growth with firm specific factors and EO from the Ethiopian context, more specifically from the context of Tigray Regional State. Besides, extra variables that were either not considered or might have been tested separately in earlier studies in Ethiopia were integrated into the regression model. In this mixed explanatory cross-sectional research, systematic random sampling techniques and structure questionnaire were applied to collect primary data from 333 small enterprises operating in five urban towns of Tigray region. Dependent variable of the study was growth of small enterprises, defined as logarithm of change in number of employees at the time of establishment and time of survey. The explanatory variables comprise of entrepreneurial orientation with three dimensions, tangible and intangible resources under the control of a given enterprises, capital structure decisions, external factors such as marketing related problems cost and accessibility of infrastructure, government policies and bureaucracy, business development services were also included in the regression model. Descriptive statistics, statistical difference tests, multiple regression analysis and Propensity Score Matching were applied for the purpose of data analysis with the help of Stata version 12 software. Majority of the small enterprises demonstrated moderate degree of entrepreneurial orientation and location nearer to major customers, entrepreneurial orientation, strong financial position, access to credit and leverage have statistically significant positive effect on growth of small enterprises which support the resource based view and static trade-off theory of capital structure as well as the perceived hypothesis. On the other hand, consistent to the hypothesis, age and size of small enterprises showed negative significant effect on growth, that supports Jovanovich’s learning model but against the Girbat’s law of proportionate effect. Moreover, the relationship between education and growth was found to be non-linear or volatile-growth of SEs tend to declined until certain level, reached a minimum level after which SEs with more educated owners tend to grow faster. This implies that unless owners’ years of education reach a very high level of schooling, a given increase in years of schooling could not necessarily result into higher growth rate. Based on the findings, the researcher suggests (i) in order to solve financial constraints of SEs, stakeholder need introduction of National Credit Guarantee Fund, Promotion of non-bank financial services, introduce Mandatory Minimum Bank Loan to small enterprises, establish specialized banking system that specifically support the small enterprise sector, (ii) provide working premises such as shades at concessional cost, (iii) facilitate establishment of small enterprise commercial centers, (iv) strengthen the clustering practices,(v) facilitate provision of adequate infrastructure at reasonable price, (vi) as TVET completed individuals outperform in growth rate, educational institutions in Ethiopia need to incorporate competence based training system and entrepreneurship into their syllabus by strengthening the industry university linkages / Business Management / DBL

Dans ma thèse doctorale, j'étudie trois facteurs importants qui caractérisent le commerce international : les différences technologiques entre les pays, les barrières à l'entrée sous la forme de coûts fixes et la migration internationale. Le premier chapitre analyse si les différences technologiques entre les pays peuvent expliquer la spécialisation dans le commerce international entre les pays. Pour mesurer le niveau de la spécialisation, je calcule les index de concentration pour la valeur des importations et des exportations et décompose la concentration totale dans la marge de produits extensive (nombre de produits commercialisés) et la marge de produits intensive (volume de produits commercialisés). En utilisant des données commerciales détaillées au niveau du produit dans 160 pays, mes résultats montrent que les exportations sont plus concentrées que les importations, que la spécialisation se produit principalement au niveau de la marge intensive du produit, et que les économies plus grandes disposent d'importations et d'exportations plus diversifiées, car elles commercialisent plus de produits. Compte tenu de ces faits, j'évalue la capacité du modèle Eaton-Kortum, le principal modèle de la théorie ricardienne du commerce, pour représenter les preuves empiriques. Les résultats montrent que la spécialisation à travers l'avantage comparatif induit par les différences de technologie peut expliquer les faits qualitatifs et quantitatifs. De plus, j'évalue le rôle des déterminants clés de la spécialisation : le degré de l'avantage comparatif, l'élasticité de la substitution et la géographie. Une implication de ces résultats est qu'il est important d’évaluer jusqu'à quel point la volatilité de production mesurée par la volatilité du PIB est motivée par la spécialisation des exportations et des importations. Étant donné le compromis entre l'ouverture du commerce et la volatilité de production, les bénéfices tirés du commerce peuvent s'avérer plus faibles que ceux estimés précédemment. Par conséquent, les politiques commerciales alternatives telles que l'ouverture graduelle au commerce combinée à la diversification de la production pour réduire la concentration de l'exportation peuvent se révéler être une meilleure stratégie que l'approche du laissez-faire. En utilisant la relation entre la taille du marché et l’entrée de firmes et produits, le deuxième chapitre évalue si les barrières à l'entrée sous la forme de coûts fixes à exporter sont au niveau de la firme ou au niveau du produit. Si les coûts fixes se trouvent au niveau de la firme, la firme multiproduits a un avantage de coût de production par rapport aux autres firmes parce qu’elles peuvent diviser les coûts fixes sur plusieurs produits. Dans ce cas, le commerce international sera caractérisé par peu de firmes qui exportent beaucoup des produits. Si les coûts fixes sont au niveau du produit, l’entrée d’un produit est associée avec l’entrée de plusieurs firmes. La raison est qu’une fois que la première firme entre et paye les coûts fixes du produit, elle crée un effet d’entrainement qui réduit les coûts fixes pour des firmes rivales. Dans ce cas, le commerce international sera caractérisé par plusieurs firmes qui vendent des variétés différentes du même produit. En utilisant des données détaillées provenant de 40 pays exportateurs à travers 180 marchés de destination, mes résultats montrent que les barrières à l'entrée se trouvent principalement au niveau du produit. Un marché plus large favorise l'expansion d'un plus grand nombre d’entreprises au sein d'une catégorie de produit plutôt que de permettre aux entreprises produisant plusieurs produits de croître dans une gamme de produits. En regardant la différence entre le nombre d'exportateurs au sein d'une catégorie de produit dans des destinations données, je trouve que le taux d'entrée de firmes augmente significativement après qu'un produit entre la première fois dans le marché. J'en déduis donc que le premier entrant réduit les coûts fixes pour les firmes suivantes. Mes recherches démontrent également que malgré une plus grande compétition sur le marché du produit, les entreprises disposent de revenus d'exportation supérieurs et sont plus susceptibles de rester sur les marchés internationaux. Ces résultats sont cohérents avec l’hypothèse que l’effet d’entrainement incite l'entrée de firmes rivales et permettent aux entreprises de produire à plus grande échelle. Cette recherche dévoile un nombre de conclusions importantes. D'abord, les politiques commerciales encouragent l'entrée de nouveaux produits, par exemple, en promouvant des produits dans les marchés de destination entraînant ainsi des retombées qui se traduiront par un taux de participation plus élevé de l'entreprise et une croissance de l'exportation. Deuxièmement, les consommateurs du pays importateur peuvent bénéficier de prix plus bas pour le produit en réduisant les barrières techniques du commerce. Troisièmement, lorsque l'on effectue des expérimentations politiques sous la forme de réduction des coûts commerciaux, il est de coutume de considérer uniquement une baisse des coûts marginaux et d'évaluer les répercussions sur le bien-être du consommateur. Cependant, un élément important des accords commerciaux est la réduction des barrières techniques au commerce grâce à la négociation de normes communes pour un produit. Négliger l'existence des barrières à l'entrée et les conséquences des réaffectations de l'industrie affaiblit l'impact des réformes commerciales. Le troisième chapitre prend en compte le rôle de l'information dans la facilitation du commerce international. Les immigrants réduisent les coûts de transaction dans le commerce international en fournissant des informations sur les possibilités d'échange avec leur pays d'origine. En utilisant des données géographiques détaillées sur l'immigration et les importations aux États-Unis entre 1970 et 2005, je quantifie l'incidence qu'ont les nouveaux immigrants sur la demande pour les importations de biens intermédiaires aux États-Unis. Pour établir le lien cause à effet entre le commerce et la migration, j’exploite l'important afflux d'immigrants d'Amérique centrale après l'ouragan Mitch. Les résultats montrent que l'augmentation de dix pour cent d'immigrants a fait croître la demande pour les importations de biens intermédiaires de 1,5 pour cent. Mes résultats sont robustes aux problèmes de la causalité inverse ou la décision d’émigrer est causée par des opportunités de faire du commerce. / In my PhD thesis I study three factors that shape international trade patterns: technological differences across countries, entry barriers in the form of fixed costs and international migration. The first chapter analyses whether technology differences across countries can explain specialization patterns in international trade. To measure specialization, I compute concentration indexes for the value of exports and imports and decomposes the overall concentration into the extensive product margin (number of products traded) and intensive product margin (volume of products traded). The results show that exports are more concentrated than imports, specialization occurs mainly in the volume of trade and larger economies have more diversified exports and imports because they trade more products. I then evaluate the ability of the Eaton-Kortum model, the workhorse model of Ricardian trade theory, to account for the observed facts. The results show that technology-induced specialization through comparative advantage can explain the qualitative and quantitative facts. The key determinants of specialization are the degree of comparative advantage, the elasticity of substitution and geography. Based on the relationship between entry and market size, the second chapter evaluates whether fixed costs are at the firm or at the product level. Within an empirical framework, I argue that fixed costs at the firm level induce a cost advantage for multi-product firms and international trade will be characterized by few firms selling many products. On the other hand, if fixed costs are at the product level, product entry is accompanied with lots of firms entry and international trade will be characterized by many firms selling different varieties of the same product. Using detailed product level data from 40 exporting countries to 180 destination markets, the results indicate that entry barriers operate at the product level. The key implication of the product fixed cost is that the firm that pays the fixed cost creates a positive externality that lowers entry costs for rival exporters and increases firm entry. Looking at firm entry within products across time and destinations, I find evidence consistent with these spillover effects. Combined these results have important implications for the effects of trade policy on market structure and on the resulting gains from trade in the exporting as well as in the importing country. The third chapter considers the role of migration in facilitating international trade. Immigrants can increase international trade by shifting preferences towards the goods of their country of origin and by reducing bilateral transaction costs. Using geographical variations across US states for the period 1970 to 2005, we quantify the impact of immigrants on intermediate goods imports. We address endogeneity and reverse causality - which arises if migration from a country of origin to a US state is driven by trade opportunities between the two locations - by exploiting the exogenous allocation of refugees within the US refugee resettlement program. Our results are robust to an alternative identification strategy, based on the large influx of Central American immigrants to the United States after hurricane Mitch. We find that a 10 percent increase in recent immigrants to a given US state raises intermediate imports from those immigrants' country of origin by 1.5 percent.

International trade ties the world together and is hypothetically fair and equal. In reality, it is highly asymmetrical and poses a significant challenge for developing countries. A massive sea change occurred in the international trade regime during the Uruguay Round of negotiations of the General Agreement on Tariffs and Trade (GATT) from 1986 to 1994. Developing countries as a whole began to embrace liberal trade policies which seemed to be the only alternative to failing import substitution industrialization (ISI). An historical comparative account describing and explaining this transformation of developing countries’ attitudes toward the GATT is used in this dissertation to provide an alternative explanation for the transition of developing countries from having little interest in the Uruguay Round of GATT negotiations to sharply changing course and adopting neo-liberal policies which supported the conclusion of the Round. Three theoretical approaches seek to explain why this change occurred, including: liberal trade theory (economic reforms), dependency theory (external forces) and constructivism (the role epistemic communities). The Uruguay Round negotiations were dynamic and heavily influenced by two power-house developing economies, India and Brazil, who were initially opposed to the Round itself. Kenya found itself in a starkly different situation with minimal ability to participate or influence negotiations. These three countries constitute the study’s illustrative case studies. As negotiations progressed, India and Brazil changed course and agreed to the Round’s ‘single-undertaking’ and the ‘inequitable Grand Bargain’ between the developed and developing economies. This subsequently led to other developing countries following suit through a powerful demonstration effect in a trade-off between the inclusion of trade in services and intellectual property for reforms in agriculture and textiles & clothing. While economic reforms began to occur and attitudes began to change during the Uruguay Round itself, assessing developing countries during the Round found that no single theoretical approach can explain developing countries’ transformation; rather each had their own trajectory for their economic reforms. A multi-dimensional conclusion provides the most comprehensive account of this transformation of the global trade regime.

In the lead up to the Year 2000 dot.com crash of publicly traded high-technology equities, Information Communication Technology (ICT) Companies proudly displayed inter-firm allegiances on their newly created websites. These collaborative relationships were in reality licensing agreements to develop or market new products internationally. Phenomena associated with ICT product development - collaboration, innovation, and internationalisation - are the core tenets of the accompanying dissertation. Leading scholars have suggested these phenomena challenge conventional economic theories of the firm. This study commences with tracing the evolution of trade and production theories from absolute advantage through to competitive advantage and introduces the concepts of non-adversarial collaborative advantage. Within the framework of the technology cycle, this dissertation then seeks to answer why firms engage in international collaborative innovation. The cycle of technological innovation is investigated and this leads to postulating a period of technological overlap and its implications for collaboration. One of the shortcomings acknowledged in the literature is the generic application of the term collaboration to cover a wide scope of inter-firm agreements. Within the literature this is referred to as a problem of multidimensionality. A model is developed in this dissertation that identifies the choices available to the firm and addresses the problem of defining collaboration. The choices provided in the developed model are more complex than simply choosing between external and internal intermediate markets. As a separable form of industry organisation, the success rates of alliance collaboration are compared to Mergers and Acquisitions (M&As) to validate issues of sustainability before examining the impact of location on innovation and collaboration. Again, theory is tested by recent events that require explanation. These events include the relocation of early stage foreign R&D to both developed and lesser-developed nations. The final chapter assesses the findings throughout this study and identifies separate and distinct roles for large and small firms in the international and collaborative commercialisation of new innovations. This central conclusion requires empirical validation and suggests the need investigate how firms shape the cycle of innovation from a reflected vantage point to the evolutionary perspective taken in this study. Further research is warranted because the literature on international innovation and collaboration is at an early stage and gaps in understanding remain.

Le marché des systèmes photovoltaïques a connu une forte croissance cette dernière décennie soutenue par des actions politiques favorables dans un contexte de transition énergétique. Pourtant, malgré ces conditions bénéfiques, le marché mondial du PV a paradoxalement traversé une période chaotique rencontrant des problèmes de surproduction, une crise industrielle et des différends commerciaux durable entre pays. Cette thèse part de ces problématiques et tente de comprendre les politiques publiques PV et les impacts sur la dynamique des technologies et des marchés. Afin de préciser ces questions, une approche systémique est utilisée pour fournir une compréhension correcte des mécanismes généraux des politiques publiques PV. Une vue d’ensemble systémique concrète de ces mécanismes est construite sur la base d’analyses théoriques et historiques en définissant les variables clés et le contexte. Une analyse rétrospective utilisant des mappings construits pour l’occasion est conduite afin de cerner les limites et défis critiques du secteur PV ainsi que les facteurs de risque. Cette thèse montre également la façon dont la nature du contexte politique change en liaison avec la dynamique du secteur PV. La thèse met en évidence que la dynamique nationale a été brisée par l’entrée de la Chine sur le secteur PV. La thèse propose au final des orientations stratégiques pour le développement du PV selon deux dimensions, nationale et internationale. Au niveau national, la thèse s’intéresse à l’autoconsommation PV en tant que manière naturelle d’utiliser l’énergie PV dans le système électrique. Cette analyse implique un changement de nature des politiques PV dans le futur. Pour terminer, afin de résoudre la crise industrielle actuelle, la thèse présente des possibilités d’actions internationales en collaboration pour créer une nouvelle demande PV dans le contexte international en recherchant des bénéfices économiques et environnementaux au niveau mondial. / Solar PV systems have experienced strong market growth over the last decade supported by favorable political reactions in the energy transition context. However, despite these favorable conditions, paradoxically, the global PV market recently went through a chaotic time encountering the overproduction issue, the industry crisis and the long-lasting trade disputes. This thesis started from these problematics to understand the PV public policies and the impacts on dynamics of technology systems and markets. In order to define those issues, a systemic approach is taken to provide an accurate comprehension of the overall mechanisms of PV public policies. The concrete systemic vision of PV policy mechanisms is constructed based on theoretical and historical analysis by defining key variables and the context. A retrospective analysis using the proposed mapping tools is conducted to understand critical limits and challenges of PV development and to identify risks factors in the sector. This thesis also demonstrates how the nature of policy context changes in combined with the dynamic feature of the PV sector. Our analysis highlights the nationwide PV policy dynamics was broken with the arrival of China in the PV sector. This thesis eventually proposes strategic orientations of PV development at the two dimensions from both national and international perspectives. At the national level, this thesis discusses on PV self-consumption as the natural way of PV power use in the electricity system. This analysis implies a change in the nature of PV policies in the future. Next, as a response to the current global industry crisis, the thesis proposes opportunities of international collaborative actions to create new PV demand in the international context in pursuit of global economic and environmental benefits.
