This thesis consists of three essays within the field of applied environmental economics, with the common basic aim of analyzing effects of Swedish environmental policy. Starting out from Swedish environmental goals, the thesis assesses a range of policy-related questions. The objective is to quantify policy outcomes by constructing and applying numerical models especially designed for environmental policy analysis. Static and dynamic multi-sectoral computable general equilibrium models are developed in order to analyze the following issues. The costs and benefits of a domestic carbon dioxide (CO2) tax reform. Special attention is given to how these costs and benefits depend on the structure of the tax system and, furthermore, how they depend on policy-induced changes in "secondary" pollutants. The effects of allowing for emission permit trading through time when the domestic long-term domestic environmental goal is specified in CO2stock terms. The effects on long-term projected economic growth and welfare that are due to damages from emission flow and accumulation of "local" pollutants (nitrogen oxides and sulfur dioxide), as well as the outcome of environmental policy when costs and benefits are considered in an integrated environmental-economic framework. / Diss.

Sustainable development is not merely a slogan, as many people think. In fact, its main outlines are contained both in International Law (Declaration of the United Nations Conference on Environment and Development ECO-92) and Brazilian Federal Constitution. These outlines reveal dimensions of an economic, social, political and environmental nature. All of these dimensions connect sustainable development with Environmental Law, particularly with the polluter pays principle. The polluter pays principle is fundamentally concerned with the issue of cost allocation: the polluter should be the entity to pay for the pollution. This principle can be implemented through direct regulation (command-and-control regulation) or market-based instruments, such as tradable emission rights or taxation. Environmental taxes are properly levied only if in compliance with sustainable development principle. / O principal objetivo desta dissertação é investigar o papel do princípio do desenvolvimento sustentável no Direto Tributário Ambiental brasileiro. Desenvolvimento sustentável não é apenas um slogan, como muitos dizem. De fato, seus principais contornos estão contidos tanto no Direito Internacional (Declaração do Rio-ECO-92) quanto na Constituição Federal brasileira. Estes contornos revelam dimensões de natureza econômica, social, política e ambiental. Todas estas dimensões ligam o desenvolvimento sustentável ao Direito Ambiental. Especificamente, com o princípio do poluidor-pagador. O princípio do poluidor-pagador está preocupado, basicamente com um problema de alocação de custos: o poluidor deve arcar com o custo da poluição que produz. Este princípio pode ser concretizado mediante regulação direta (regras de comando e controle) ou instrumentos econômicos (servem de exemplo a comercialização de licenças ambientais e a tributação). Tributos ambientais somente podem ser cobrados se respeitarem o princípio do desenvolvimento sustentável.

本文將貿易政策與環境政策做連結, 建構一雙邊貿易之架構, 設立一三階段之序列賽局,以之探討: 當具有跨國性質之消費性污染存在時, 在考量兩國政府皆有誘因在環境政策上採取非合作的態度下, 兩國政府應如何藉由貿易政策之協定, 訂定其最適之出口品補貼政策, 以矯正環境政策非合作下之不效率。 本文研究發現: 在兩國政府僅能夠進行政策的部分合作時, 當需求參數愈大, 兩國政府之最適貿易政策是應將給予其各自國家出口品之單位補貼調升;但若伴隨消費財貨所排放之污染對環境具有較高之邊際污染, 或是其本身之外溢效果愈強, 兩國政府對出口品之最適補貼則應該調降。我們同時也發現, 此時即使各國政府之最適貿易政策是調降出口補貼, 會使得各國之污染稅稅率更低, 但卻不會使其更加偏離兩國政府在環境政策上合作下之最適稅率, 並且仍會為全球帶來更高之社會福利。 / This paper constructs a reciprocal-market model, which contains a three-stage game to investigate how the two countries decide the optimal export subsidy agreement when they do not coordinate their environmental policy. We find that the level of optimal export subsidy should decrease with the strength of transboundary pollution, which is associated to consumption activities. In addition, the export subsidy agreement should increase with the demand parameter. We also find that even a reduction in the export subsidy will decrease the non-coordinated environmental tax rate, it will not deviate the tax rate away from the coordinated one and still enhance the social welfare.

Nesse escopo, introduz-se a problemática ambiental, demonstrando a dificuldade atual enfrentada pelo homem referente aos baldios e exibindo a teoria por traz deste verídico drama ambiental que se vivencia, pensado por Garret Hardin – a Tragédia dos Bens Comuns. Ademais, faz-se uma construção acerca do que é esse novo Direito Humano, explicando o seu surgimento por meio da própria evolução histórica da sociedade e a sua consagração enquanto direito consuetudinário internacional de terceira dimensão. Na sequência, abordar-se-á a insuficiência da “positivação” desse Direito para contornar a Tragédia, sendo essa a principal problemática que se buscará responder no texto, partindo da crise paradigmática do positivismo até o surgimento de um novo paradigma, o qual observa a função desempenhada pelo sistema jurídico e, por causa disso, busca outros ferramentais para contornar o problema, como a Análise Econômica do Direito, oriunda do Direito e Economia. Logo, estudar-se-á os instrumentos originários das Ciências Econômicas, particularmente, as ideias edificadas por Arthur Pigou e Ronald Coase para controlar o problema, além de duas metodologias da microeconomia significativamente relevantes para o Direito, quais sejam, a Teoria da Escolha Racional e a Teoria dos Jogos. Por fim, analisar-se-á detalhadamente as contribuições geradas por esses inputs econômicos, desde a monetarização do meio ambiente à criação de incentivos positivos, os quais tendem a ser a “nova” solução para contornar não só o estruturalismo do sistema jurídico, como também o problema ambiental, vez que motiva os agentes sociais a agirem em prol das condutas esverdeadas. Desta feita, mostrar-se-á dois exemplos dessa aplicação, uma no panorama doméstico, envolvendo o tema dos tributos ambientais, e outra no panorama internacional, no que compete aos mercados transacionáveis como aquele elucubrado pelo Protocolo de Kyoto. Para tanto, traça-se um resgate teórico-qualitativo acerca do tema, com intuito de revisar a bibliografia existente, porém, sem o condão de querer esgotá-la. / This thesis aims at studying the problems arising from the environment, trying to establish a method of truly attaching social efficacy to this common right to all individuals, since the environmental problems that have emerged worldwide escape from normality, intrinsically affecting human beings in their human right to a healthy and balanced environment. In this scope, it will be primarily introduced the environmental problems, demonstrating the current difficulty faced by individuals concerning the commons and showing the theory behind this true problem mankind face as Garret Hardin exposed, called The Tragedy of the Commons. Moreover, a historical construction of what this novel human right is will be made, in order to explain its establishment as a customary rule of international law of third dimension. Furthermore, the insufficiency of such “positivation” to fight the Tragedy will be addressed, constituting the main quest of his text, departing from the positivism paradigmatic crisis until the erection of a new paradigm that observes the functional character of law. Due to such view, the necessity of finding in other sciences mechanisms to overcome this current issue, such as incorporating the Economic Analysis of Law methodology, originated form the Law and Economics School will be clarified. Thus, the Economic Science instruments will be studied; chiefly, the Pigouvean and Coasean concepts, and two significant theories for the Law field, which are the Rational Choice and Game Theory. Above and beyond, the detailed contributions generated by these economic inputs will be discussed from the monetization of the environment to the emergency of positive incentives, which tend to be the “new” key to solve both the structural view of the law system and the environmental problem, as it encourages the social agents to act greenly. In this sense, two examples of such application will be shown: one in the domestic system involving environmental taxes, and the other in the international arena, concerning the transactional markets (cap-and-trade) as the one established by the Kyoto Protocol. For such analysis, a theoretical-qualitative research on the matter will be made, intending to review the existing bibliography, but not expecting to exhaust it.

本研究包括3個研究議題。第1個議題旨為估算不同部門別（包括農業、工業、服務業與運輸業）的能源燃燒產生CO2排放之組成因素的貢獻量，係藉由拉氏指數法和算術平均迪氏指數法之加法型態，拆解5種不同的因素（包括：碳密集度、部門結構、能源密集度、人口及經濟規模等），觀察其對於CO2排放變動之影響。本文採用台灣1992-2008年的各部門別的資料作為分析的基礎，研究結果顯示，以上部門的經濟規模對於CO2排放的貢獻呈現巨幅的正向效果；人口因素則呈現微幅的正向或負向的影響；而碳密集度對於CO2排放減量有正面的影響，並發現此乃是構成改善能源結構並導致CO2排放減量的最重要因素；能源密集度因素的影響，除服務業以外，其餘部門均呈現負向影響，此一結果顯示，大部分部門要進一步改善其能源效率頗為困難，是以未來致力於減排的努力，應著重於使用乾淨能源，尤其是以再生能源作為替代能源 (Liaskas et al., 2000)；此外，值得注意的是，部門結構因素對於大部分的產業，如農業、工業和運輸業的CO2排放減量有正向的影響，據此可推論，我國的部門結構已漸趨向於低耗能產業（如服務業）發展。另外，本文採用近似不相關迴歸模型，探討各項政策工具（如環境稅、進口關稅）與經濟變數（如貿易條件及時間趨勢等）透過以上5種不同的組成因素，對於CO2排放變動的影響效果作一分析，其實證結果可供決策者制定減排政策的參考。 第2個議題係為建立節能減排的有效政策工具，須先詳實掌握各項政策工具對節能減排與經濟成長的影響，乃深入回顧相關文獻之理論與實證方法，據以建立適合台灣的3E聯立模型，並進行實證分析，藉以推估多項政策工具（如環境稅、關稅等及能源價格等）與經濟變數（如貿易條件、所得等）對於節能減排與GDP的影響。實證分析結果顯示，台灣之能源消費、CO2排放、及GDP對於各項政策工具與經濟變數之彈性不僅各異其趣，而且有些彈性並非固定不變，可隨時間經過動態調整。 第3個議題係利用台灣1992-2008年之農業、工業、服務業與運輸業等部門別的panel data，仿照Battese and Coelli (1995)提出之隨機邊界(Stochastic Frontier Analysis, SFA)模型，建構隨機生產邊界函數 (stochastic production frontier function)與隨機能源需求函數 (stochastic energy demand frontier function)，利用最大概似法估算出各部門的GDP與能源需求之隨機邊界與技術效率 (technical efficiency, TE)，並據此實證結果提出政策建議。 / The thesis includes 3 issues of research. The first research aims at identifying the factors that have influenced change in the level of various sectors (agriculture, industry, service and transport) CO2 emissions from energy use. By means of both Laspeyres index method and the arithmetic mean weight scheme expressed separately in the additive form, the observed changes are analyzed into five different factors: CO2 intensity, structural change, sectoral energy intensity, sectoral employing population and output level. The application study refer to 4 sectors of Taiwan between 1992 and 2008. The obtained decomposition results indicate that the examined sectors the value calculated for the output level effect present the highest value appearing positive contribution of CO2, and the contribution from population is slightly increased or decreased, while CO2 intensity has beneficially influenced the reduction of CO2 emissions, as well as the improvement of fuel mix found to be the most important factor that lead to the reduction of emissions. In most of the examined sectors for the energy intensity factor present positive effect on CO2 emissions, the only exception is service sector showing negative impact on CO2 emissions, which can be stated as Liaskas et al. (2000) that as further improvements in energy efficiency in most sectors become more difficult, efforts to reduce CO2 emissions will be predominantly directed towards the use of clean energy forms and especially towards the deployment of renewable energies. It also should be noted that structural change has positively influenced the abatement of CO2 emissions for the most sectors such as agriculture, industry and transport. We conclude it shifts towards less energy-intensive service sector, due to have negative influenced the observed decrease in CO2 emissions for higher energy use sectors (industry and transport) and agriculture,. In this article, we also use a seemingly unrelated regression to further investigate the policy tools how to change in CO2 emissions level by the five different factors. The results indicate that policymakers may reduce emissions considerably through various policy instruments. The second issue focuses on initiating effective policy to save energy and reduce emission, one needs to reasonably capture the potential impacts of various policy instruments on energy consumption, CO2 emission and economic growth, the second research, after extensively reviewing the literature, builds a locally ideal empirical model that facilitates the estimation of various policy elasticities. The empirical results indicate that policy elasticities may not only differ from one to the others, but also change dynamically, implying the 3E impacts of some policy instruments might be weakening over time. The main goal of the third article is to provide a detailed analysis of productivity and efficiency measurement for panel data on four different sectors from Taiwan over the period 1992-2008. We use a stochastic frontier model set by Battese and Coelli (1995) to build a stochastic production frontier function and a stochastic energy demand frontier function, which are estimated by maximum likelihood to obtain a stochastic frontier of GDP and energy demand, as well as technical efficiency. On this empirical results, we suggest that policymaker may simultaneously make top-down policies (green tax reform, increasing environmental tax etc.) and bottom-up policies (fuel price in line with prices of gas in global markets) to increase energy efficiency in different sectors.

This thesis consists of four essays within the field of environmental economics. Computable General Equilibrium models have been used to assess the economic consequences of greenhouse gas policies. The focus is mainly on the Swedish economy, but the EU economies and the global economies are also analyzed in one essay each. The costs and effects of a unilateral Swedish decision to reduce carbon dioxide emissions are analyzed in essay I. The results of a unilateral reduction are compared to the results of an implementation of an EU multilateral agreement. The results indicate that if Sweden unilaterally decides to increase its CO2 tax, total EU CO2 emissions will increase, i.e. there will be a “carbon leakage effect”. Furthermore, an EU multilateral implementation of a CO2 tax will induce lower welfare (excluding environmental benefits) in Sweden, as compared to the situation where the same tax is unilaterally introduced.In the second essay we analyze the Swedish environmental goals conforming to the Kyoto Protocol, when simultaneously meeting national goals to alleviate acidification and eutrofication effects by reducing SO2 and NOx pollutants. We have found that when secondary benefits of measures aiming at reducing CO2 are taken into account, it may still be in the government’s interest to nationally decrease CO2, instead of engaging in seemingly low-cost trading. The principles for allocation emission permits are many, and in the third essay I focus on principles based on economic welfare theory. My main conclusion from these simulation exercises is that the distribution rule based on the different assumptions on social welfare function and some other more ad hoc distribution rules offers quite large changes in welfare, distributions of emission rights and contrary to earlier literature, I find that the initial distribution not only gives second-order effects but affects equilibrium prices and therefore, income.In the fourth essay I focus on how households’ demand for transport services can be improved in CGE-models. A differentiation between trip purposes and trip length, a complementary relationship between work journeys and labor supply, and a subdivision of households by density of population and income, influences the numerical results in a direction increasing the negative welfare effect of a carbon target, as compared to the non-extended model. / Diss.
