Full textDenna forskningsstudie i tillämpad matematisk statistik och industriell ekonomi syftar till att bestämma de vinegenskaper som driver vinförsäljningen i Sverige, samtidigt som man undersöker hur monopolet i Sverige påverkar alkoholförsäljningen och efterfrågan. Data samlades in från Systembolaget, som är den enda butikskedjan för alkohol i Sverige. En multipel linjär regressionsanalys utfördes på 4 931 observationer från Systembolagets försäljningsstatistik från 2019. Kovariaterna var typen av vin, smak, pris, storlek, ursprungsland, ekologiskt klassificerat och etiskt certifierat. Den slutliga modellen innehöll 18 variabler där smakparametrarna dominerade modellen. Resultaten visar på att viner från Australien, Italien och Portugal har en fördel när det gäller vinförsäljningen i Sverige, medan vin från Sverige har en negativ korrelation med den sålda volymen. Andra resultat tyder på att vinproducenter bör göra etiskt producerade viner. Ur ett nationalekonomiskt perspektiv är alkoholmonopolet i Sverige inte ett vanligt monopol. Dessutom anses monopolet ha haft en negativ inverkan på alkoholförsäljningen genom att bland annat sänka efterfrågan med hjälp av en strikt alkohollag. De positiva aspekterna av Sveriges alkoholmonopol är den övergripande bättre hälsan hos det svenska samhället och konsultationen som erbjuds i butikerna. Denna studie har bidragit till tidigare forskning och även givit vinproducenterna en bättre överblick över de faktorer som driver vinförsäljning i Sverige.

Full textA União Europeia, através da Directiva Comunitária 98/30/CE, de 21 de Julho de 1998, estabeleceu regras para a liberalização dos mercados do gás natural dos vários Estados - Membros, tendo como ponto fundamental a abertura do sector a terceiros. Neste âmbito, Portugal deverá começar a tomar um conjunto de medidas tendo em vista a liberalização deste sector por forma a permitir o acesso a toda a cadeia de valor do mercado: compra, transporte e venda. Para Portugal, uma vez que foi considerado um mercado emergente, a Comissão Europeia estabeleceu o ano de 2008 como prazo para a liberalização do mercado, sendo necessário que até lá se criem condições que permitam o seu pleno funcionamento. Neste contexto, a criação de uma entidade reguladora, que garanta o perfeito funcionamento do mercado e o cumprimento das regras de concorrência, de livre acesso às infraestruturas existentes, e de transparência, que deverão entretanto ser estabelecidas, deverá ser um dos primeiros passos a dar nesse sentido. A abertura do mercado e a criação de uma entidade reguladora adequada deverão ser suportados pelo profundo conhecimento do sector do gás natural em Portugal, das suas características e mecanismos de articulação, por forma a permitir o estabelecimento de regras eficientes de funcionamento do mercado e a actuação adequada e pertinente da entidade reguladora. O objectivo do presente trabalho é assim, com base no estudo da Teoria Económica da Regulação, na análise da legislação nacional e comunitária existente, das experiências verificadas noutros países europeus e das características do mercado português, identificar os parâmetros que garantam a competitividade do sector e estabelecer o enquadramento de competências e uma estrutura organizativa e funcional para a Entidade Reguladora que deverá ser criada para acompanhar o processo de liberalização do sector do gás natural em Portugal e regular o mercado.
The European Union, through Directive 98/30/EC, dated 21 st July 1998, established rules for the liberalisation of the gas markets within its Member States. A fundamental aspect of this directive is the concept of third party access to the system. Portugal has to adopt several measures in order to prepare itself for the liberalisation of its own market in order to allow third party access to its entire gas market value chain. However, Portugal has been considered an emergent market and has therefore been allowed to postpone market opening until 2008. Till then, it will be necessary to create conditions ín order to assure market efficiency, being one of the first measures to be taken the implementation of a regulatory body that will guarantee the introduction of competition in the market, the establishment of transparency rules and free access to the system. Market opening and the implementation of a regulatory body, adequate to the Portuguese gas market characteristics, must be supported by a profound knowledge of the national natural gas sector in order to allow the introduction of efficient rules and to promote the regulatory body^ proficiency. Thus, one of the objectives of the present study is the identification of factors that will guarantee market competition and efficiency, based on the economic regulation theory study, on the analysis of the Portuguese and European Union legislation, of the experience of other European countries regarding market liberalisation and also on the study of the Portuguese market characteristics. Another objective of the present study is the identification and definition of objectives, tasks and a possible structure for the regulatory body that should be created to supervise the liberalisation of the Portuguese natural gas market and to regulate it.

Full textThis dissertation deals with discussions that took place at the Institute of Social Research during its exile in the United States in the first half of the 1940\'s. By approaching a debate on National Socialism organized by the Institute at Columbia University in 1941 attended by Friedrich Pollock, Franz Neumann, Otto Kirchheimer, Arcadius R. L. Gurland and Herbert Marcuse , it tracks the formation of Horkheimer and Adornos critique of monopoly capitalism. As the dissertation shows, the approach of monopolistic society adopted by Horkheimer and Adorno fuses with a critique of the process of civilization. The conflation of the critique of historical present with the critique of civilization culminates in the Dialectic of Enlightenment, a jointly authored book that was concluded in 1944. By viewing this work as an answer to the Columbia debate, the dissertation reconstructs the debate and, furthermore, seeks to establish mediations between it and Horkheimer and Adornos theoretical output up to and including the Dialectic of Enlightenment. The dissertation analyzes the transformations that occurred as well as new determinations that emerged in the intellectual trajectory of the two authors during this period.

Resumo: Nesta dissertação apresentamos uma descrição da dualidade elétrica-magnética e seus aspectos clássicos e quânticos.

Os aspectos clássicos da teoria foram explicados pela conjetura de Montonen e Olive 1977 [7]. Explorando os aspectos quânticos da teoria, notamos a importância de introduzir supersimetria, principalmente supersimetria estendida, onde tiramos vantagem da propiedade de holomorficidade, a qual nos leva aos teoremas não renormalizáveis, onde o cálculo é mais simples. Focamos na teoria de gauge supersimétrica N = 2 SU(2). A teoria é completamente resolvível para baixas energias.

Abstract: In this dissertation we present a description of the electric-magnetic duality and their classical and quantum aspects. Our analysis starts from the suggested magnetic monopoles by Dirac in 1931 [1] and goes until the work of Seiberg and Witten in 1994 [27]. In the classical description, we need to introduce the magnetic monopoles in order to make manifest the electricmagnetic duality. Later, the origin of monopoles becomes clear when we start from a Yang-Mills theory. The classical aspects of the E-M duality are covered in the Montonen-Olive conjecture 1977[7]. Working on the quantum aspects of the theory, we note the importance of introducing supersymmetry. Specially for extended supersymmetry, where we take advantage of the holomorphicity property, which leads us to the non-renormalizable theorems, where the computation is easier. We focus on theN = 2SU(2) supersymmetric gauge theories. It turns out that the theory is fully solvable at the low energies regime[27]. Most of this work is based on reviews about the Seiberg and Witten duality [30],[31],[32]

En el programa de Doctorat de Telecomunicacions per la Universitat Politècnica de València. Com a part del procés d'investigació es va participar en els següents projectes d'investigació: Plataforma de servicios para ciudades inteligentes con redes M2M densas (TIN2013-47272-C2-1-R), Entrepreneurship in Heterogeneous Wireless Networks (COHWAN, TIN2010-21378-C02-02) i ATLAS -Dynamic network slicing in 5G Radio Access. També es va realitzar una estada doctoral en l'IMT Atlantique en Rennes-França. Com a resultat d'aquaquests activitats es van publicar diversos articles científics que permeten sustentar els models de negoci per a MVNOs presentats en el present document. En aquest estudi, es plantegen models de negoci que se sustenten en el desenrotllament de les característiques tècniques de 4G i 5G, que faciliten la compartició d'infraestructura dels MNOs. També s'analitza l'estat de l'art que permet sustentar la viabilitat tècnica dels models basats en la compartició d'infraestructura, que ha permès disminuir les barreres d'entrada al mercat i el desenvolupament de nous models de negoci per als MVNOs. No obstant això, els nous models que permeten la compartició d'infraestructura han de ser analitzats des-de l'aspecte econòmic per a determinar la viabilitat dels mateixos. Específicament, en el primer model s'analitza la viabilitat econòmica d'un MVNO que brinda el servei a la seua base d'usuaris i divideix el seu tràfic de xarxa a dos MNOs, els que lloguen la seua capacitat de xarxa al MVNO. En l'anàlisi del model es considerentant les característiques del sistema com les econòmiques. Respecte a les característiques del sistema, un MVNO proporciona servei als usuaris finals utilitzant el suport d'infraestructura de dos MNOs. El servei proporcionat pel MVNO, es modelada per mitjà d'una cua M/M/1, on cada usuari genera paquets de forma independent seguint un procés de Poisson. Els temps de servei dels paquets es distribueixen exponencialment. En el sistema proposat, la mètrica de qualitat més rellevant és el temps mitjà de servei, que comprén tant el temps d'espera com el temps mitjà de servei. L'acord entre el MVNO i els MNOs, és tal que el MVNO dividirà el tràfic de la xarxa entre els dos MNOs i pagarà a cada MNO pel tràfic servit a través de la seua infraestructura. Respecte a les característiques econòmiques, els incentius es modelen mitjançant les utilitats dels usuaris i els beneficis dels operadors. En el segon model, s'analitza la viabilitat econòmica de dos escenaris per a un model de negoci en què un MNO lloga la seua infraestructura de xarxa al MVNO i cada operador serveix a la seua pròpia base d'usuaris. El primer escenari denominat monopòlic, el MNO dona servei a les dos bases d'usuaris (MNO i MVNO). En el segon escenari denominat estratègic, el MNO dona servei a la seua base d'usuaris, a més a més, lloga la seua infraestructura al MVNO per a que aquest puga prestar servei a la seua base d'usuaris. Per als dos escenaris, la xarxa s'ha modelat per una cua amb prioritat, utilitzant una disciplina de servei DPS. En l'anàlisi de compartició d'infraestructura, es considera un pagament al MNO per cada usuari que accedeix al servei de MVNO. Finalmente, para determinar la viabilidad económica de los diferentes escenarios propuestos para los modelos de negocio, se utilizan conceptos de microeconomía, teoría de juegos y teoría de colas, la cuales han permitido conocer las decisiones en equilibrio que toman los operadores, así como las decisiones en equilibrio de los usuarios; de esta manera se ha obtenido el efecto de estas decisiones sobre los beneficios de todos los agentes del modelo y se han identificado las condiciones bajo las cuales estos nuevos modelos de negocio son viables en entornos de redes 4G y 5G. Como resultado del análisis de los modelos de negocio para los diferentes escenarios propuestos, se observa que la asociación entre MNOs y MVNOs a través de la compartición de infraestructura es viable económicamente para los modelos propuestos. En relación a los usuarios, su comportamiento es sustancial para determinar la viabilidad económica de los diferentes modelos de negocio propuestos, por lo tanto, resulta imprescindible explorar diferentes funciones de utilidad que expresen el comportamiento de los usuarios en estudios futuros. En cuanto a los operadores, en el primer modelo de negocio se demuestra que, la provisión de capacidad de red es un mecanismo válido para optimizar los beneficios de los operadores. Así como, en el segundo modelo de negocio, se demuestra que, la compartición de infraestructura entre un MNO y un MVNO es deseable desde el punto de vista de los usuarios para el modelo de negocio estratégico, ya que permite un mayor número de usuarios. Mientras que, desde el punto de vista económico el modelo de negocio monopólico es más deseable debido a que ofrece un incentivo mayor a los operadores. En resumen, en esta tesis se demuestra la viabilidad económica de modelos de negocio de compartición de infraestructura entre MNOs y MVNOs, soportados técnicamente por las características tecnológicas de las redes móviles de ultima generación.
[EN] This thesis has been developed within the framework of the research line of Economics and Regulation of Telecommunications. In the PhD program of Telecommunications by the Universitat Politècnica de València. As part of the research process, we participated in the following research projects: Service Platform for Smart Cities with Dense M2M Networks (TIN2013-47272-C2-1-R), Entrepreneurship in Heterogeneous Wireless Networks (COHWAN, TIN2010-21378-C02-02) and ATLAS-Dynamic network slicing in 5G Radio Access. A doctoral stay at the ITM Atlantique in Rennes, France, was also arranged. As a result of these activities, several scientific articles were published which support the business models for MVNOs presented in this document. In this study, business models based on the development of the technical characteristics of 4G and 5G are proposed, which facilitate the sharing of the infrastructure of MNOs. In this regard, this document analyzes the state of the art that supports the technical feasibility of models based on infrastructure sharing, which has lowered barriers to market entry and the development of new business models for MVNOs. However, the new models that infrastructure sharing allows, must be analyzed from an economic aspect to determine their viability. Specifically, the first model analyses the economic viability of an MVNO that provides the service to its user base and splits its network traffic between two MNOs, which rent their network capacity to the MVNO. The analysis of the model considers both the characteristics of the system and the economic ones. In terms of system characteristics, one MVNO provides service to end-users using the infrastructure support of two MNOs. The service provided by the MVNO is modelled through an M/M/1 queue, where each user generates packets independently following a Poisson process. The service times of the packages are distributed exponentially. In the proposed system, the most relevant quality metric is the average service time, which comprises both the waiting time and the average service time. The agreement between the MVNO and the MNOs is such that the MVNO will split the network traffic between the two MNOs and pay each MNO for the traffic served through its infrastructure. In terms of economic features, incentives are modelled through user profits and operator profits. In the second model, we analyze the economic viability of two scenarios for a business model in which, an MNO rents its network infrastructure to the MVNO, and each operator serves its user base. In the first scenario, called monopoly, the MNO serves both user bases (MNO and MVNO). In the second scenario, called strategic, the MNO serves its user base, as well as leases its infrastructure to the MVNO to serve its user base. For both scenarios, the network has been modelled by a priority queue, using a DPS discipline. In the infrastructure sharing analysis, a payment to the MNO is considered for each user that accesses the MVNO service. Finally, to determine the economic viability of different scenarios proposed for the business models, concepts of microeconomics, game theory and queuing theory are used, which have allowed us to know the equilibrium decisions made by the operators, as well as the equilibrium decisions made by the users. In this way, the effect of these decisions on the profits of all the agents in the model has been obtained, and the conditions under which these new business models are viable in 4G and 5G network environments have been identified. As a result of the analysis of the business models for the different scenarios proposed, it is observed that the association between MNOs and MVNOs through infrastructure sharing is economically viable for the proposed models. In relation to users, their behavior is substantial to determine the economic viability of the different proposed business models; therefore, it is essential to explore different utility functions that express user behavior in future studies. As for the operators, the first business model demonstrates that the provision of network capacity is a valid mechanism for optimizing operators’ profits. As well as, in the second business model, it is demonstrated that, the sharing of infrastructure between an MNO and an MVNO is desirable from the users’ point of view for the strategic business model since it allows a greater number of users. Whereas, from an economic point of view, the monopolistic business model is more desirable because it provides a greater incentive for operators. In summary, this thesis demonstrates the economic viability of business models of infrastructure sharing between MNOs and MVNOs, technically supported by the technological characteristics of the latest generation mobile networks.

Full textPatent law is easily subject to acquisition and abusive exercise although it's sacred due to his qualification of property rights and strengthened by the international agreements and national laws. The failure of some patent offices amplifies the possibilities of this abusive appropriation. Situations of abuse of patent rights are more frequent in the high technology sector (pharmaceutical, biotechnology and computer industry).On the one hand, these abuses hinder the realization of the function assigned to patent law, and on the other hand, they restrict freedom of competition. The legal measures of patent law and those of competition law impose limits on the power of the patentees which is stemming from their exclusive right, to realize the general interest. However, these rules don't protect private individuals whose interests can be affected by the abusive use of patent rights. The theory of abuse of law, a general principle of the common law, fills this gap. In spite of its limited and prudent application on the patent right, its utility is not to neglect. It helps to prevent and to sanction the abnormal use of the patent right. The comparison between the Egyptian and French law shows that the difference in the level of economic and industrial development between the two countries affects their legislative policy with regards to patent law

This study is about the secularization according to Peter L. Berger (theory of secularization) and according to Rodney Stark/William Sims Bainbridge (rational choice theory).

Full textThe communications world is moving from a standalone devices scenario to a all-connected scenario known as Internet of Things (IoT), where billions of devices will be connected to the Internet through mobile and fixed networks. In this context, there are several challenges to face, from the development of new standards to the study of the economical viability of the different future scenarios. In this dissertation we have focused on the study of the economic viability of different scenarios using concepts of microeconomics, game theory, non-linear optimization, network economics and wireless networks. The dissertation analyzes the transition from a Human Type Communications (HTC) to a Machine Type Communications (MTC) centered network from an economic point of view. The first scenario is designed to focus on the first stages of the transition, where HTC and MTC traffic are served on a common network infrastructure. The second scenario analyzes the provision of connectivity service to MTC users using a dedicated network infrastructure, while the third stage is centered in the analysis of the provision of services based on the MTC data over the infrastructure studied in the previous scenario. Thanks to the analysis of all the scenarios we have observed that the transition from HTC users-centered networks to MTC networks is possible and that the provision of services in such scenarios is viable. In addition, we have observed that the behavior of the users is essential in order to determine the viability of a business model, and therefore, it is needed to study their behavior and preferences in depth in future studios. Specifically, the most relevant factors are the sensitivity of the users to the delay and to the amount of data gathered by the sensors. We also have observed that the differentiation of the traffic in categories improves the usage of the networks and allows to create new services thanks to the data that otherwise would not be used, improving the monetization of the infrastructure and the data. In addition, we have shown that the capacity provision is a valid mechanism for providers' profit optimization, as an alternative to the pricing mechanisms. Finally, it has been demonstrated that it is possible to create dedicated roles to offer IoT services in the telecommunications market, specifically, the IoT-SPs, which provide wireless-sensor-based services to the final users using a third party infrastructure. Summarizing, this dissertation tries to demonstrate the economic viability of the future IoT networks business models as well as the emergence of new business opportunities and roles in order to justify economically the development and implementation of the new technologies required to offer massive wireless access to machine devices.
El món de les telecomunicacions està canviant d'un escenari on únicament les persones estaven connectades a un model on pràcticament tots els dispositius i sensors es troben connectats, també conegut com a Internet de les Coses (IoT) , on milers de milions de dispositius es connectaran a Internet a través de connexions mòbils i xarxes fixes. En aquest context, hi ha molts reptes que superar, des del desenrotllament de nous estàndards de comunicació a l'estudi de la viabilitat econòmica dels possibles escenaris futurs. En aquesta tesi ens hem centrat en l'estudi de la viabilitat econòmica de diferents escenaris per mitjà de l'ús de conceptes de microeconomia, teoria de jocs, optimització no lineal, economia de xarxes i xarxes inalàmbriques. La tesi analitza la transició des de xarxes centrades en el servici de tràfic HTC a xarxes centrades en tràfic MTC des d'un punt de vista econòmic. El primer escenari ha sigut dissenyat per a centrar-se en les primeres etapes de la transició, en la que ambdós tipus de tràfic són servits davall la mateixa infraestructura de xarxa. En el segon escenari analitzem la següent etapa, en la que el servici als usuaris MTC es realitza per mitjà d'una infraestructura dedicada. Finalment, el tercer escenari analitza la provisió de servicis basats en MTC a usuaris finals, per mitjà de la infraestructura analitzada en l'escenari anterior. Als paràgrafs següents es descriu amb més detall cada escenari. Gràcies a l'anàlisi de tots els escenaris, hem observat que la transició de xarxes centrades en usuaris HTC a xarxes MTC és possible i que la provisió de servicis en tals escenaris és viable. A més a més, hem observat que el comportament dels usuaris és essencial per a determinar la viabilitat dels diferents models de negoci, i per tant, és necessari estudiar el comportament i les preferències dels usuaris en profunditat en estudis futurs. Específicament, els factors més rellevants són la sensibilitat dels usuaris al retard en les dades recopilats pels sensors i la quantitat dels mateixos. També hem observat que la diferenciació del tràfic en categories millora l'ús de les xarxes i permet crear nous servicis emprant dades que, d'una altra manera, no s'aprofitarien, la qual cosa ens permet millorar la monetització de la infraestructura. També hem demostrat que la provisió de capacitat és un mecanisme vàlid, alternatiu a la fixació de preus, per a l'optimització dels beneficis dels proveïdors de servici. Finalment, s'ha demostrat que és possible crear rols específics per a oferir servicis IoT en el mercat de les telecomunicacions, específicament, els IoT-SPs, que proporcionen servicis basats en sensors inalàmbrics utilitzant infraestructures d'accés de tercers i les seues pròpies xarxes de sensors. En resum, en aquesta tesi hem intentat demostrar la viabilitat econòmica de models de negoci basats en xarxes futures IoT, així com l'aparició de noves oportunitats i rols de negoci, la qual cosa ens permet justificar econòmicament el desenrotllament i la implementació de les tecnologies necessàries per a oferir servicis d'accés inalàmbric massiu a dispositius MTC.

Full textNos últimos anos uma nova classe de materiais, os metamateriais, emergiu na comunidade científica. O uso desses materiais torna possível alcançar propriedades eletromagnéticas singulares, como o índice de refração negativo. Hoje existem vastas aplicações que usufruem destas propriedades especiais, como os sensores, mantas de invisibilidade e antenas, onde se procura o aperfeiçoamento de suas características intrínsecas. Com base nestas considerações, este projeto buscou desenvolver estruturas metamateriais para controle das propriedades de radiação de antenas na faixa de micro-ondas, tais como diretividade e ganho. Mais especificamente, foram utilizados os metamateriais quirais, principalmente devido ao fenômeno de rotação do campo eletromagnético que abre a possibilidade de controle mais eficiente das propriedades de radiação de antenas. Além disso, os metamateriais quirais, por se mostrarem uma alternativa mais atraente para se obter meios com índice de refração zero ou negativo, possibilitam um maior grau de liberdade no projeto de diferentes estruturas. Este trabalho contempla, ainda, todas as etapas de projeto de tais estruturas, quais sejam: projeto, modelagem computacional, fabricação, e caracterização das estruturas. Mostramos melhorias para o ganho que, em alguns casos, chega a mais do que o dobro do ganho da antena monopolo convencional e para o parâmetro de perda de retorno, que atinge valores mínimos. Nós também mantivemos uma boa eficiência e melhoramos o casamento de impedância de entrada. Finalmente, vale salientar que essa nova tecnologia também apresenta grande potencial de ser aplicada em dispositivos de telecomunicações, com o intuito de aprimorar a comunicação baseada em antenas.

The thesis has three parts 1) We deduce conditions under which firmswill allow agents to pirate their non-rival products. 2) Analyze the decision for firms to merge when other firms can choosebetween projects of varying variances. 3) We show how the characteristics of a payment (amount, frequency) as well as theenvironment of agents (wealth, dynamics), influence the discount rates of agents

Mais precisamente estabelecemos um dicionário entre a teoria de calibre da mecânica quântica de uma partícula carregada sujeita a um campo eletromagnético e o estudo das conexões em brados por círculos e por retas complexas. Em seguida, analisamos dois objetos de estudo em física utilizando o conhecimento adquirido no estudo da geometria de espaços brados. As classes de Chern e a holonomia de uma conexão nos fornecerão uma visualização geométrica de, respectivamente, monopolos magnéticos e o efeito Aharonov-Bohm

Although prior studies on simple monopoly spatial price theory have bend conducted in a world with fixed market area, a firm in the real world often confronts the market with various sizes. In order to fully understand that how does the firm react to the market size vary, this paper attempts to examine the relative economic advantages under alternative pricing policies in a world with two basic assumptions. One is non-linear demand function and another is the market size, which is treated as a parameter in the model. We will show that as the market size increases, the optimal uniform delivered price increases, but the optimal price under mill pricing decreases. Moreover and more importantly, we will show that in a world with varying market size, some findings obtained by prior studies in regard to the economic benefit comparison between alternative pricing policies no longer hold.

In 1978, The United States Congress passed the Airline Deregulation Act ending the economic regulation of airline industry since 1938. As for surface transportation, it was the Interstate Commerce Commission Termination Act of 1995 that made the economic regulation by ICC since 1887 to the end. Why did the U.S. Congress remove the economic regulation of transport industries?In reality, after removing the regulation from airline industry, the competition between firms not only made fare decreasing, but also prompted firms to adopt more effective hub-and-spoke route structure. Like the airline industry, the effects of deregulating railroad industry, which based on the Staggers Act of 1980, have been the decreasing fare and higher profit for firms. Owing a great part to the economist's efforts, United States has accomplished the economic deregulation of transport industries. From the economic theory, however, not all monopoly industries have to be regulated. Natural monopolies can be divided into strong and weak ones by its cost function. Moreover, each group can be divided into two classes basing on the existence of barriers of entry. When an industry has no entry barriers and chooses sustainable prices, there is no need to execute any economic regulation. This paper consists of two parts. The first part mainly refers to normative theory by introducing the sustainable price of natural monopoly as key factor to determine whether executing economic regulation or not. When examining the existing of sustainable price, we usually consider subsidy-free price which usually appeared in transport industries and conditions to be a contestable market, and firms generally adopt welfare-maximum price, like Ramsey price. Although there is no direct relationship between sustainable price and Ramsey price, the regulatory agency that pursues welfare-maximum should pay attention to it. Game theory could be used to find out the necessary and sufficient conditions for the existence of sustainable price. It usually occurs that an industry, which doesn't need any economic regulation, from normative point of view, has been regulated in reality. We may use the positive theory of economic regulation to interpret, and this is the essence of the second part of this paper. In the positive analysis, there are many theories seeking the reasons why economic regulation happens. From normative analysis of positive theory to capture theory, all can't completely interpret it. It is the economic theory of regulation that can use model to interpret reasons and predict it. It indicates that the reason of why regulation happens isn't on economic consideration, it is the relative interest groups' pressure functions that push regulatory and legislators to adopt pro-interest group regulation. This paper uses Taiwan's open highway bus policy as an instance. Through discussing with relative persons, we confirm the economic theory of regulation. Comparing the effects with other countries' deregulation, we should move to more regulatory reform.

Theory and Design of the Compact Monopole Antenna for Circular Polarization Student:Chia-Wei Hsu Advisor(s):Professor Chien-Jen Wang Master’s Department of Electrical Engineering , National University of Tainan ABSTRACT In this thesis, a coplanar-waveguide (CPW)-fed dual-band antenna for applications of the multi-system integration has been demonstrated. The resonance analysis of the stepped-impedance (SI) monopole is presented by using the transmission-line analysis method. The frequency-response characteristics of the SI-monopole, such as the resonance condition and harmonic response, are systematically summarized. Furthermore, utilizing several techniques, such as bent monopole, asymmetric ground plane, and an L-shaped slot etched in the ground plane, a right-hand circularly polarized (RHCP) radiating wave at 1.57 GHz and a left-hand circularly polarized (LHCP) radiating wave at 2.33 GHz are excited for the global positioning system (GPS) and the satellite digital audio radio (SDAR) service system. After optimization of the geometrical parameters of the proposed antenna, the measured impedance bandwidths of a reflection coefficient < - 10 dB range from 1.40 to 2.98 GHz and from 4.48 to 6.27 GHz, and thus covers most of the commercial wireless communication systems, such as GPS, DCS, PCS, SDAR, IMT-2000, WLAN, and LTE 2300/2600. The measured 3-dB axial ratio (AR) bandwidths are about 80 MHz at 1.57 GHz and 100 MHz at 2.33 GHz. Keywords:Stepped impedance, transmission-line analysis method, resonance condition, harmonic response, and axial ratio.
