This thesis's objective is to whether the customs duty's dissipating its strength in its ability to create balanced conditions for the presence of competing goods in one market that are from in two mutually inhomogeneous production environments and to propose a conceptual framework for long-term action. Application of grounded theory based on comparative analysis of quantitative data within a case study allowed for a creation of data-emergent theory in the subject area of international trade. A core category of connection between an individual's wage and the level of customs duty levied on an imported good has been developed to offer an explanation of the core phenomenon of the customs duty's lost strength. Through the theoretical conceptualisations, the variable of developed core category impacted the creation of the variable of the ratio comparing the amount of customs duty levied on imported good with the average monthly wage of the individual. The conceptual model explains 3 theoretical propositions explore the analogy which results in explanation of the core premise of this thesis. Applied emergent theory, allowed for proposal of long-term action of the alternative to customs in a form of an increased value added tax on imported goods.

La presente investigación consiste en el análisis de las barreras comerciales que influyeron en las exportaciones de quinua provenientes de la región de Lima durante el marco de la relación comercial entre los Estados Unidos y el Perú entre los años 2008 y 2018. En los últimos años, empresas exportadoras han logrado vender grandes cantidades a Estados Unidos, sin embargo, durante el intercambio comercial se ha evidenciado barreras reflejadas en las medidas no arancelarias que obstaculizan la relación comercial entre los dos países. El objetivo general de la presente investigación es determinar las barreras comerciales que influyeron en las exportaciones de quinua de las empresas de Lima al mercado de Estados Unidos. Por medio de una metodología de tipo mixta, se analizó el comportamiento de las variables descritas como barreras comerciales mediante dos análisis: cualitativo, a través de las entrevistas a profundidad aplicadas a los principales actores y expertos en el tema que proporcionan información del sector; y un análisis cuantitativo, con el uso de un modelo gravitacional con datos econométricos, obtenidos de diferentes fuentes como INEI, SUNAT, Sistema de gestión de la información MSF y OTC de la OMS, GRAVITY del CEPII, entre otros, información que ayudó a desarrollar los objetivos planteados. El principal resultado de ambos análisis concluye que, el comportamiento de las variables MSF y OTC durante los años 2008 y 2018 indicaron ser un factor influyente en la variabilidad de las exportaciones peruanas hacia Estados Unidos. Sin embargo, se encontró que el precio internacional fue una variable que influyó en las exportaciones de quinua, pero no constituyó una barrera comercial, puesto que, a pesar de que el precio de venta se habría elevado, las cantidades exportadas no habrían disminuido. / The present investigation consists of the analysis of trade barriers who were an influence on quinoa exports from the region of Lima during the bilateral trade agreement between the United States and Peru during the years 2008 and 2018. In the last years, companies based on Lima have managed to export large amounts of quinoa, however, trade with the US market has revealed barriers that have hindered free trade between these two countries. The general objective of the research is to establish trade barriers have influenced exports of quinoa through the years in the bilateral agreement context. In this context, the use of a mixed methodology was necessary to mix qualitative and quantitative study variables. The qualitative type were developed using in-depth interviews applied to the main actors and experts in the subject that provided more information of the sector and, a quantitative type, which used the gravitational model with econometric data from different sources such as, INEI and SUNAT. The SPS and TBT information were found it with the help of a system of the WHO, GRAVITY of the CEPII, among others, information that helped to develop the stated objectives. The main result of both analyses leads us to conclude that the variables influenced the export of quinoa from the Lima region during the bilateral trade agreement between the United States and Peru during the years 2008 and 2018 were, sanitary and phytosanitary measures (SPS) and technical barriers to trade (TBT). However, it was found that the international price was a variable that influenced quinoa exports but it did not constitute a trade barrier, since, despite the fact that the sale price would have risen, exported quantities would not have decreased. / Tesis

This study examines the comparative impact of multilateral trade agreements on intra-regional trade in the Southern African Development Community (SADC) and the Economic Community of West African States (ECOWAS) regions in Africa. Annual data was gathered from 2000 to 2018 and dynamic panel data and econometric techniques were used to control for individual country characteristics, endogeneity, serial correlation, heteroscedasticity and interdependencies between the countries in each region. Two estimations were done, one using the tariff measures of multilateral agreements, the second using non-tariff measures of multilateral agreement. The results of the empirical analysis show that the SADC region has a slight edge over ECOWAS in terms of technological progress and investment, especially in trade infrastructure. However, the ECOWAS levels of employment and economic growth are higher than those in the SADC region. These differences further translate into differences that drive intra-African trade in these regions, and how they relate to the role of multilateral agreements in intra-African trade in each of these regions. While technology and investment are key drivers and enhancers of intra-African trade in SADC countries, economic growth and employment stand out as key enhancers of intra-African trade in ECOWAS, especially where multilateral agreement is represented by tariff measures. This study reports that when non-tariff measures are used to represent multilateral agreements, export trade costs, in addition to investment and technology, are the key drivers of intra-African trade in SADC countries. For ECOWAS, under non-tariff measures of multilateral agreements, only economic growth drives intra-African trade. / Business Management / D. Phil. (Business Management)

服務貿易「模式四」涉及生產要素之一的勞動力跨境移動，其所能帶來之貿易利得相當可觀；然而，勞動力之移動向來不為地主國青睞，各國針對此等自然人服務提供者多所管制，造成模式四貿易之諸多障礙，致使模式四佔服務貿易總量之比例極低，而亟待開發。在盤點多邊與非多邊體制下WTO之GATS與TPP協定消弭模式四貿易障礙之成果後，本文發現，國際間對於模式四貿易障礙之消弭必須持續推動，方能早日獲致模式四貿易自由化附隨之經濟利益。奠基於上述多邊與非多邊體制之成果，本文提出未來國際間在持續消弭模式四貿易障礙之可行方向，並以現正如火如荼談判中之「服務貿易協定（TiSA）」為例，印證本文所建議之方向有其可行性。 / Mode 4 of trade in services entails the cross border movement of one of the factors of production: labor. The potential gains from labor mobility can be substantial; however, labor mobility has never been welcome. Numerous regulations imposed by the receiving countries on the natural persons as service suppliers create barriers to the Mode 4 trade, resulting in the fact that Mode 4 trade accounts for little proportion of all four modes of service supply. After conducting stock takes on the elimination results of Mode 4 trade barriers through the GATS and the TPP Agreement respectively under multilateral and non-multilateral trade regimes, this article argues that efforts to remove Mode 4 trade impediments should continue in order that the ensuing welfare gains from Mode 4 trade liberalization can ultimately be achieved. Based on the aforementioned elimination results under both multilateral and non-multilateral regimes, this article proposes several approaches to further elimination of Mode 4 trade barriers, taking the ongoing Trade in Services Agreement (TiSA) as an example to verify the feasibility of the proposed approaches.

<p>The purpose of this research is to examine the impact of liberalisation of trade in services on African LDCs by highlighting the importance of services trade through Mode 4 (temporary movement of natural persons).37 The paper will examine the nature of liberalisation to this Mode under the existing GATS framework, critically analyse the constraints on engaging in negotiations, specifically the national barriers that are hindering this movement, and make suggestions on ways of improving the nature of commitments on movement of natural persons in terms of Mode 4 to favour LDCs as laid down in Article VI of the GATS.</p>

Face aux nouveaux problèmes relatifs aux barrières environnementales de nos jours, l'OMC se trouve dans une situation embarrassante : d'une part, elle est largement considérée comme le "centre de gravité" du contrôle des barrières environnementales, d'autre part, il existe encore de grandes lacunes dans la régulation relative à la valeur environnementale au sein de l'OMC, ce qui mettrait en cause l'efficacité du droit de l'OMC dans cette régulation. Sans un contrôle efficace, le système du libre-échange risque de se dégrader. C'est la raison pour laquelle nous avons choisi de consacrer une étude comparative aux barrières environnementales au commerce international dans le cadre de l'OMC. Pour tenter de trouver des solutions aux problèmes qui se présentent aujourd'hui en matière de barrières environnementales, nous devons nous interroger sur deux questions majeures. D'une côté, les nouvelles barrières environnementales relatives au changement climatique dépassent le cadre de l'OMC, le droit actuel de l'OMC ne paraît pas en mesure de donner une réponse satisfaisante aux problèmes qui en résultent, et de l'autre, il existe un grand écart entre les pays développés et ceux en développement au niveau des barrières environnementales mises en place, ce qui provoque des déséquilibres dans le commerce international. Les analyse que nous avons effectuées dans cette étude portant à la fois sur les ACR et l'OMC nous permettent de conclure que l'OMC jour un rôle irremplaçable face aux problèmes de barrières environnementales, cela nous conduit à proposer des solutions permettant au droit de l'OMC de mieux concilier le commerce international et la protection de l'environnement à l'échelle mondial / Facing the new problems about the green trade barriers today, WTO is actually in an embarrassing situation : one side, it is widely considered as the ''center of gravity' 'for controlling the green trade barriers ; on the other side, there is still an important lacuna in the regulation of the environmental values in the WTO, which questions the effectiveness of WTO's law in this regulation of green trade barriers. Without the effective control, the free trade system takes a risk to be degraded. That's the reason why we undertake a study comparative on the subject of the green trade barriers in the framework of WTO. Attempting to find the solution of the problems related to green trade barriers, we have to ask two questions. One side, the new type of green trade barriers about the climate change beyond the capacity of WTO, the current law of WTO does not appear to give a satisfactory response to the resulting problems ; on the other side, there is a big gap between the green trade barriers set up by the developed countries and developing countries, which causes absolutely an imbalance in the international free trade. The analyse that we did in this study relating both to the regional trade agreements and WTO allow us to conclude the WTO plays an irreplaceable role in face of challenges of the green trade barriers today. This conclusion leads us to propose the solutions which may offer a better balance between the international trade and the environmental protection on a global scale

El presente trabajado a realizar consiste en el Análisis de las barreras comerciales que influyeron en las exportaciones de Uvas Frescas provenientes de la región de Piura dentro del Tratado de Libre Comercio entre Estados Unidos y Perú durante el periodo 2009-2019. En la última década quedo evidenciado el incremento de las exportaciones de uvas fresca hacia los Estados Unidos, en el cual intervino una serie de barreras comerciales que influyeron en las exportaciones de dicho producto en el marco del TLC entre ambos países. Es por ello, el objetivo de la investigación es Analizar de las barreras comerciales que influyeron en las exportaciones de Uvas Frescas provenientes de la región de Piura dentro del Tratado de Libre Comercio entre Estados Unidos y Perú durante el periodo 2009-2019. A través de la investigación de tipo mixta, se realizó el análisis de las variables identificadas como barreras comerciales por medio de dos tipos de análisis. En primer lugar, cualitativo, se realizaron entrevistas a profundidad a los representantes de instituciones, expertos en temas agrícolas y empresas de la región de Piura. En segundo lugar, cuantitativo a través del modelo gravitacional. El cual empleo datos econométricos que se obtuvo de la búsqueda de fuentes como SUNAT, INEI Sistemas de gestión de información para MSF, OTC y Precios internacionales de uvas frescas, entre otros, los cuales sirvieron para poder desarrollar los objetivos que se plantearon en la investigación. Los resultados del análisis cualitativo concluyen que las MSF y OTC son barreras comerciales que influyeron en las exportaciones de uvas frescas de la región de Piura dentro del Tratado de Libre Comercio entre Estados Unidos y Perú durante el periodo 2009-2019.Por otro lado, los precios internacionales no representan una barrera comercial que influyeron en las exportaciones de dicho producto. Esto se manifiesta en qué precio lo determina el mercado. Por lo contrario, los resultados cuantitativos en base al modelo gravitacional demostraron lo contrario tanto las MSF, OTC y Precios Internacionales no constituyen como barreras comerciales para exportar la uva fresca hacia el mercado de los Estados Unidos. / The present work has been carried out consists of the Analysis of the trade barriers that influenced the exports of Fresh Grapes from the Piura region within the Free Trade Agreement between the United States and Peru during the 2009-2019 period. In the last decade, the increase in exports of fresh grapes to the United States was evidenced, in which a series of trade barriers intervened that influenced the exports of said product within the framework of the FTA between both countries. For this reason, the objective of the research is to analyze the trade barriers that influenced the exports of Fresh Grapes from the Piura region within the Free Trade Agreement between the United States and Peru during the 2009-2019 period. Through mixed type research, the analysis of the variables identified as trade barriers was carried out by means of two types of analysis. First, qualitatively, in-depth interviews were conducted with representatives of institutions, experts in agricultural issues and companies in the Piura region. Second, quantitative through the gravitational model. Which used econometric data that was obtained from the search of sources such as SUNAT, INEI Information management systems for MSF, OTC and International prices of fresh grapes, among others, which served to develop the objectives that were raised in the investigation .The results of both qualitative analysis conclude that the SPS and OTC are trade barriers that influenced the exports of fresh grapes from the Piura region within the Free Trade Agreement between the United States and Peru during the 2009-2019 period. , international prices do not represent a trade barrier that influenced the exports of said product. This is manifested in what price is determined by the market. On the contrary, the quantitative results based on the gravitational model showed the opposite; both the SPS, OTC and International Prices do not constitute trade barriers to export fresh grapes to the United States market. The keywords used in the research: Trade Barriers, Sanitary and Phytosanitary Measures, Technical Barriers to Trade, International Price of Fresh Grapes, Exports and Gravitational Model. / Tesis

The Gravity Equation estimated used as the dependent variable the exports of Paraná and as independent variables the Gross Domestic Product (GDP) and population of the state, GDP and population of importers countries of products from Paraná, the distance in kilometers between the state´s capital and the capital of the importer country, commodities prices in the international market, the area of importers countries and the dummies crisis, China, NAFTA, European Union and MERCOSUR. The Equation was estimated using panel data models by Pooled, Fixed Effects and Random Effects. The tests of Chow, Hausman and Breusch-Pagan LM indicated that the best model to be analyzed is the Random Effects. The tests of Breusch -Pagan and Wooldridge indicated, respectively, the presence of heteroscedasticity and autocorrelation. Thus, the Random Effects model was estimated with heteroscedasticity correction, with correction for autocorrelation and both fixes. According to the Equation estimated by the Random Effects model with heteroscedasticity and autocorrelation correction, the variables GDP and population of Paraná, GDP and population of importers countries and commodities prices were statistically significant and their coefficients showed, with the exception of the Paraná´s GDP, a positive relationship with the Paraná´s exports. The variables distance and area of importers countries were statistically insignificant and their coefficients showed an inverse relationship with exports of Paraná. The dummies China, NAFTA, European Union and MERCOSUR were statistically insignificant. Their coefficients showed a positive relationship between the Paraná´s exports and China and MERCOSUR and negative with NAFTA and the European Union. The dummy crisis was statistically significant, indicating that reduction in demand caused by the global financial crisis led to a reduction of 11,68% in Paraná´s exports. However, between 2008 and 2009, the Paraná´s exports fell by 26,3%. Thus, the occurrence of crisis partially explained the drop in exports of Paraná between 2008 and 2009. This can be explained by non-tariff barriers imposed by countries in response to the financial crisis. / O objetivo deste estudo foi analisar o impacto da crise financeira de 2008 nas exportações do Paraná através do Modelo Gravitacional. A Equação Gravitacional estimada utilizou como variável dependente as exportações do Paraná e como variáveis independentes o Produto Interno Bruto (PIB) e a população do estado, o PIB e a população dos países importadores de produtos paranaenses, a distância em quilômetros entre a capital do estado e a capital do país importador, o preço das commodities no mercado internacional, a área dos países importadores e as dummies crise, China, NAFTA, União Europeia e MERCOSUL. A Equação foi estimada por meio de dados em painel pelos modelos Pooled, de Efeitos Fixos e de Efeitos Aleatórios. Os testes de Chow, Hausman e LM de Breusch-Pagan indicaram que o melhor modelo a ser analisado é o de Efeitos Aleatórios. Os testes de Breusch-Pagan e de Wooldridge indicaram, respectivamente, a presença de heterocedasticidade e de autocorrelação. Assim, o modelo de Efeitos Aleatórios foi estimado com correção de heterocedasticidade, com correção de autocorrelação e com ambas as correções. De acordo com a Equação estimada pelo modelo de Efeitos Aleatórios com correção de heterocedasticidade e autocorrelação, as variáveis PIB e população paranaense, PIB e população dos países importadores e preço das commodities foram estatisticamente significativas e seus coeficientes indicaram, com exceção do PIB do Paraná, relação positiva com as exportações paranaenses. As variáveis distância e área dos países importadores foram estatisticamente insignificantes e seus coeficientes mostraram uma relação inversa com as exportações do Paraná. As dummies China, NAFTA, União Europeia e MERCOSUL foram estatisticamente insignificantes. Seus coeficientes indicaram relação positiva entre as exportações paranaenses e a China e o MERCOSUL e negativa com o NAFTA e a União Europeia. A dummy crise foi estatisticamente significativa, indicando que redução da demanda global ocasionada pela crise financeira acarretou redução de 11,68% nas exportações paranaenses. Entretanto, entre 2008 e 2009, as exportações paranaenses apresentaram queda de 26,3%. Assim, a ocorrência da crise explicou parcialmente a queda das exportações do Paraná entre 2008 e 2009. Isto pode ser justificado pelas barreiras não tarifárias impostas pelos países em resposta à crise financeira.
