Shocks dei prezzi internazionali e sviluppo: un approccio di equilibrio generale con applicazioni al Burkina Faso / INTERNATIONAL PRICE SHOCKS AND DEVELOPMENT: A GENERAL EQUILIBRIUM APPROACH WITH APPLICATIONS TO BURKINA FASO

BELLU', LORENZO GIOVANNI 13 July 2011 (has links)
Questa tesi, strutturata in tre documenti autonomi ma logicamente connessi, si propone di analizzare alcuni problemi, idee e prospettive relativi allo sviluppo. In particolare, il primo documento “Sviluppo e paradigmi di sviluppo: un’analisi delle visioni prevalenti” fornisce un quadro comparativo dei principali modelli di sviluppo adottati da diversi paesi (visione, azioni specifiche e processi di attuazione) e ne evidenzia specificità, analogie e differenze. Il secondo documento: “Analisi d’impatto delle politiche de degli shocks dei prezzi internazionali: Modelli CGE per un paese non industrializzato importatore netto di petrolio e dipendente dagli aiuti esterni”, mette in luce come le informazioni utilizzabili nei processi di formulazione delle politiche che si ottengono da un modello CGE dipendano sia dalle assunzioni relative alla struttura del modello che dalla struttura del sistema economico oggetto dell’indagine. In particolare, le variazioni del tasso di cambio reale si ripercuotono sul resto del sistema tanto più, quanto più il paese riceve finanziamenti ed aiuti dall’estero. Il terzo documento “Shocks dei prezzi internazionali in Burkina Faso: valutazione degli impatti socio-economici con modelli CGE” si propone di valutare l’impatto degli shocks dei prezzi internazionali di prodotti alimentari, petrolio, fertilizzanti e cotone, avvenuti nella prima decade degli anni 2000, sul sistema socio-economico del Burkina Faso, esempio di paese non industrializzato importatore netto di petrolio e dipendente dagli aiuti esteri. Da una lettura complessiva dei tre documenti emerge che, per assicurare uno sviluppo globale sostenibile nel lungo periodo, alla luce dei problemi di sviluppo emergenti e dei vincoli globali quali il vincolo energetico, i cambiamenti climatici, le disuguaglianze, i conflitti e le migrazioni è necessario rivedere la maggior parte dei paradigmi di sviluppo adottati finora. / This thesis, structured in three individual but logically interlinked papers aims at addressing select development issues, ideas and perspectives. More specifically, the first paper “Development and development paradigms: a (reasoned) review of prevailing visions” provides a comparative analysis of the prevailing development models adopted by different countries (visions, specific actions and implementation processes) and highlights their analogies, differences and specificities. The second paper “Analyzing policy impacts and international price shocks: Alternative Computable General Equilibrium (CGE) models for an aid-dependent less-industrialized country”, highlights how relevant information for policy making obtained by CGE models depend both on the assumptions regarding the structure of the model and on the structure of the socio-economic system under investigation. More specifically, the more the country receives foreign grants and loans, the more the variations of the real exchange rate due to price shocks affect the country’s socio-economic system. The third document “International price shocks in Burkina Faso: assessing development impacts with a Computable General Equilibrium (CGE) approach” assesses the impact of the international price shocks of food, oil, fertilizers and cotton, occurred in the first decade of the new millennium, on Burkina Faso, a less-industrialized oil-dependent and foreign aid-dependent country. Reading across the three papers of this work, it emerges that, to achieve globally equitable and sustainable development objectives, in the light of the emerging issues and global constraints such as exhaustible fossil energy, climate changes, inequalities conflicts and migrations, it is necessary revising most of the development paradigms adopted so far.

Three Essays on the Economics of Climate Change

Arif, Faisal 05 March 2012 (has links)
Thesis Abstract: Chapter I: Regional burden sharing of GHG mitigation policies – A Canadian perspective. The distribution of the burden of cost arising from the reduction of greenhouse gas (GHG) emissions is a contentious issue in policy discussions; more so among regional jurisdictions in the federalist countries with decentralized authorities over environmental regulations. In this setting, often the policy discussions are focused on the distribution of regional emission reduction targets that, in turn, entails negotiations over the distribution of the scarcity rents and the regional transfers of wealth. The allocation of regional emission entitlements is thus a key factor that could hinder the political feasibility of a national GHG mitigation policy. In this paper, we build a multi-region computable general equilibrium (CGE) model of the Canadian economy to assess the implications of different burden sharing rules governing the national GHG abatement policy with a cap-and-trade system of emission permits. In addition to assessing the impacts of traditional regional emissions allocation rules that involve intra-regional transfers of wealth, we consider a particular emission allocation that avoids such transfers, which may be a more palatable option given the context of likely fierce negotiations over the issue. Our results indicate to differing outcomes depending on the allocation policy in use. The CGE framework is also able to shed light on the transmission mechanisms that drive the results underlying the policy options. Chapter II: Endogenous technological change and emission allowances. Given the imminent threat of global warming due to GHG emissions, a number of emission mitigation policies have been proposed in the literature. However, they generally suffer from the classical equity-efficiency trade-off. High costs from equity concerns often render environmental policies politically unattractive and thus hard to implement. Recent advancement in the climate policy modeling literature that incorporates endogenous technological change (ETC) into the framework can potentially bring new insights into this debate. Using an inter-temporal, multi-sector CGE approach with ETC incorporated into the framework, this paper builds a model that focuses on the equity-efficiency debate for the policymakers. Canada is chosen as the country of investigation for this purpose. The paper provides a new welfare ranking of four permit allocation policies that address the equity-efficiency trade-off. In a second-best setting with pre-existing distortions, output-based allocation (OBA) of emission permits is compared to three other policy options: (i) an emissions trading system with grandfathered allocation (GFA), (ii) an auction permit trading system where permit revenue is recycled to lower payroll taxes (RPT), and (iii) a hybrid of OBA and R&D subsidy (O-R&D). We find that adapting OBA, as well as O-R&D, is welfare improving over GFA. The implicit output subsidy, entailed in the OBA policy, mitigates against the rising cost effect in the GFA policy. This is reinforced through added investment incentive in R&D when ETC in incorporated into the framework. With O-R&D, since the R&D subsidy corrects for market imperfections in the knowledge accumulation process, the effect is further bolstered, culminating into mitigation of uneven distributional outcome for energy-intensive industries as a whole. Contrary to previous results, we also find that, in terms of the welfare metric, OBA unequivocally improves the distributional outcome across sectors as compared to the RPT policy. Inclusion of ETC also unequivocally generates a higher welfare ranking for all permit policy schemes. Chapter III: Emission permit banking and induced technological change. This paper attempts to undertake an exploratory research by integrating two themes in the emission mitigation policy literature, which include: the inter-temporal emission permit banking and borrowing and the role of induced technological change in emission mitigation. Using a simple optimal control approach, we construct a unified framework that evaluates the optimal path of emissions and the optimal trajectory of permit price when both inter-temporal banking and borrowing of permits and the effects of induced technological change (ITC) are present. We find that ITC leads to a declining emission trajectory over time. The effect of ITC on the optimal permit price path, however, is ambiguous and critically depends on the extent of marginal cost saving that emanates from emission-saving technological innovation.

總體審慎政策-流動性覆蓋比率-之動態隨機一般均衡分析 / Examination of Liquidity Coverage Regulation with A DSGE Framework

吳奕信, Wu, Yi-Xin Unknown Date (has links)
本文的研究目的為,在一個包含銀行部門的動態隨機一般均衡模型的架構中,探討流動性覆蓋比率限制在利率的信用管道中所扮演的角色以及其對政體經濟的影響為何。在銀行的資產配置決策內生的情形下,加入流動性覆蓋比率的限制,透過放款的勞動成本與抵押品價值來刻畫金融摩擦;本文發現當經濟體系遭受生產與放款的外生衝擊時,流動性覆蓋比率的限制會增強政策利率的信用管道效果,並且相較於無流動性覆蓋比率限制之模型而言,具流動性覆蓋比率限制的模型,其銀行資產配置的變動幅度與金融摩擦的程度皆較大。 / The main purpose of this paper is to explore the role of the liquidity coverage ratio (LCR) in the credit channel and how it influences the overall economy in a dynamic stochastic general equilibrium (DSGE) model with banking sector. Commercial banks endogenously choose their optimal portfolio of assets under the liquidity coverage ratio restriction. On the other hand, we describe the financial friction through the labor cost of making loans and collateral value. We find that when the economy is exposed to exogenous shocks in production and lending, the liquidity coverage ratio will enhance the effect of credit channel. Compared with the model with no LCR restriction, the degree of change of the bank asset allocation and the financial friction are larger in the model with LCR restriction.

Changements d'usage des sols, marchés agricoles et environnement / Land use change, agricultural markets and the environment

Valin, Hugo 17 March 2014 (has links)
La contribution des changements d’usage des sols aux émissions de gaz à effet de serre d’origine anthropique est estimée à 17% pour la décennie 2000, en grande partie liée à la déforestation. L’un des facteurs principaux de ces changements est l’expansion des terres agricoles pour les besoins locaux de développement, mais également sous l’effet des exportations stimulées par la mondialisation. Pour cette raison, des préoccupations nouvelles surgissent quant aux effets des politiques sur l’usage des sols par le biais des marchés internationaux. Ce travail présente trois illustrations concrètes où ces effets peuvent être d’ampleur conséquente : i) l’intensification de l’agriculture dans les pays en voie de développement, ii) les accords commerciaux, et iii) les politiques d’agrocarburants. Les résultats montrent que pour chacune de ces politiques, les réponses des marchés sont susceptibles de jouer un rôle déterminant dans le bilan des gaz à effet de serre. L’atténuation du changement climatique par l’intensification des cultures conduit à des réductions d’émissions, mais l’effet rebond de la demande pourrait annuler une part substantielle des bénéfices attendus sur les surfaces de terres cultivées. L’exemple d’un possible accord entre l’Union européenne et le Mercosur montre les effets négatifs que peut induire la libéralisation de certains produits agricoles, si des mesures d’accompagnement adéquates ne sont pas mises en place. Enfin, l’effet des changements indirects d’affectation des sols est susceptible d’effacer une part substantielle des réductions d’émissions alléguées aux agrocarburants. Les réponses de l’affectation des sols aux différentes politiques dépendent néanmoins de nombreux paramètres comportementaux, et il est difficile d’en fournir une estimation chiffrée précise. Plusieurs approches de modélisation sont utilisées ici pour quantifier ces effets et explorer les intervalles de confiance découlant des estimations actuelles de la littérature économétrique. La prise en compte de cette externalité dans l’évaluation des politiques publiques nécessite des approches nouvelles intégrant mieux les différents niveaux d’incertitude sur ces effets. / Land use change is estimated to have generated 17% of anthropogenic greenhouse gas emissions in the 2000s, a large part coming from deforestation. The main driver of these emissions is expansion of agricultural activities, for the need of local development in tropical regions. However, they have also been caused by the dynamics of globalisation which has stimulated agricultural trade flows. Thus, today, there are new concerns with respect to how agricultural policies are influencing land use changes in other parts of the world through international market responses. In this work I consider three concrete illustrations of where these effects can be of significant magnitude: i) agriculture intensification in developing countries, ii) trade agreements, and iii) biofuel policies. I find that for each of these policies, market responses are likely to play a significant role in the final greenhouse gas emission balance. Mitigation of emissions through agricultural intensification could have quite beneficial outcomes, but the rebound effect on the demand side would offset a large part of greenhouse gas emission savings attributable to the land sparing effect. With the example of a possible EU-MERCOSUR trade agreement, I also show the adverse effect of liberalising certain specific agricultural products closely connected to land use change dynamics without adequate accompanying measures. Last, the indirect land use change effect of biofuels is likely to offset a large part of their alleged GHG emission savings. Land use change responses depend on many behavioural parameters, however, and providing precise estimates constitutes a challenge. I use different modelling approaches to quantify their magnitude and extensively explore the level of confidence on the basis of current state of econometric findings.New approaches should be elaborated to take account of this externality in public policy assessments, together with an appropriate consideration of the uncertainty ranges associated with these effects.

Term Structure of Interest Rates: Macro-Finance Approach / Term Structure of Interest Rates: Macro-Finance Approach

Štork, Zbyněk January 2010 (has links)
Thesis focus on derivation of macro-finance model for analysis of yield curve and its dynamics using macroeconomic factors. Underlying model is based on basic Dynamic Stochastic General Equilibrium DSGE approach that stems from Real Business Cycle theory and New Keynesian Macroeconomics. The model includes four main building blocks: households, firms, government and central bank. Log-linearized solution of the model serves as an input for derivation of yield curve and its main determinants -- pricing kernel, price of risk and affine term structure of interest rates -- based on no-arbitrage assumption. The Thesis shows a possible way of consistent derivation of structural macro-finance model, with reasonable computational burden that allows for time varying term premia. A simple VAR model, widely used in macro-finance literature, serves as a benchmark. The paper also presents a brief comparison and shows an ability of both models to fit an average yield curve observed from the data. Lastly, the importance of term structure analysis is demonstrated using case of Central Bank deciding about policy rate and Government conducting debt management.

The sustainability of economic growth in Abu Dhabi

Smeets, Bram 10 July 2013 (has links)
Abu Dhabi has experienced an unprecedented development during the last half century, growing rapidly from a remote desert settlement to a thriving metropolitan. Today, the Emirate ranks among the countries with the highest GDP per capita in the world, and this impressive development is anticipated to continue in the decades to come.<p><p>However, there are several challenges to the sustainability of the current economic prosperity, and the environmental degradation that was caused by the rapid development is an important factor in this context. Today, the United Arab Emirates as a country has the highest ecological footprint per capita in the world and Abu Dhabi, hosting the major part of the heavy industries and oil extraction capacity in the country, has an even larger footprint. Key drivers of this poor environmental track-record are the high greenhouse gas emissions and water consumption levels.<p><p>This deterioration of environmental conditions has growing implications for the economic welfare and physical well-being of the population. So far, the government's environmental policy is mostly symbolic, and concrete policy measures are largely lacking today. On the contrary, there are crucial elements in the governmental policy that have strong negative impacts on environmental conditions and thus on the sustainability of Abu Dhabi's growth, such as generous implicit subsidies on energy commodities and water and an ambitious strategy for economic growth, depending on a strong expansion of heavy industry.<p><p>This poses the question how environmental conditions will develop, when the population boom and economic expansion are anticipated to continue. However, the academic literature on environmental sustainability issues in Abu Dhabi as well as in the wider Gulf region is limited. Moreover, applied policy studies on the topic are absent as well.<p><p>This dissertation intends to contribute to the academic literature as well as to insights from existing policy studies, by projecting the impact of sustained economic growth on environmental conditions in Abu Dhabi. It compares a baseline scenario of economic growth with the four most relevant policy options aimed at footprint reductions available to policy makers in the Emirate: i) The introduction of a nuclear power plant; ii) An abandonment of utility price controls; iii) Shifts in the subsidization policy of water and energy markets; iv) Energy efficiency improvements in selected parts of the economy.<p><p>A recursively dynamic, multi-sectoral computable general equilibrium (CGE) model is used to generate the results in this dissertation, focusing on the two most important aspects of the ecological footprint in Abu Dhabi mentioned above. The CGE model is calibrated to a SAM for Abu Dhabi for 2009, and its specification is chosen to facilitate a focus on energy consumption and sustainability issues. Besides, it is extended by an environmental module and a fossil fuel module, and it incorporates several other modifications that are tailored to the Abu Dhabi economy.<p><p>Simulation results under a baseline scenario of economic growth show that carbon emissions will grow by 282% by 2030 compared to the base year 2009, and water consumption is anticipated to increase by 312%.<p><p>The introduction of nuclear plants, at the scale that is previewed today, will yield a reduction in emissions of 2.6% compared to the baseline scenario. The economic impact will be positive, with a 0.5% increase in GDP and small gains in employment levels.<p><p>Price liberalizations in the utility markets are a politically sensitive theme. When implemented, they can yield a 7.6% reduction in emissions and a 2.3% in water consumption by 2030 (vs. baseline). However, the economic cost involved amounts to 0.3% of GDP.<p><p>An abandonment of subsidies in the energy and water markets can lead to a 11.1% drop in carbon emissions, and a 28.8% decline in water consumption vs. baseline. The domestic economic impacts of this change are negative, but the GDP shows a modest 0.6% growth, due to improvements in the foreign trade balance.<p><p>Finally, efficiency improvements can lead to reductions in carbon emissions (13.8%) and water consumption (17.5%) compared to the baseline, and bring economic gains of 1.0% of GDP.<p><p>All four simulated policy scenarios in this dissertation bring about reductions in the ecological footprint, compared to the baseline as described above. Nonetheless, the consumption levels of energy and water as well as the related carbon emissions will be substantially higher in 2030 than they are today, under each of these scenarios. As a policy implication, the dissertation therefore finds that the previewed deterioration in environmental conditions requires active policy, if current welfare and prosperity are to be sustained. When assessed in the appropriate policy context, environmental conservation and improvements in the ecological footprint should be treated with a higher priority in the broad portfolio of development goals in Abu Dhabi.<p> / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

[pt] ENSAIOS SOBRE OS EFEITOS DO COMÉRCIO COM A CHINA NO MERCADO DE TRABALHO E NA POLÍTICA COMERCIAL / [en] ESSAYS ON TRADE POLICY AND LABOR MARKET EFFECTS OF THE CHINA TRADE SHOCK

FLAVIO LYRIO CARNEIRO 17 September 2021 (has links)
[pt] Esta tese é composta por três capítulos que enfocam o crescimento da China como um experimento quasi-natural de forma a avaliar os efeitos de choques de comércio exterior sobre a economia política da política comercial e sobre a dinâmica do mercado de trabalho e desigualdade de salários no Brasil. No primeiro capítulo, utilizamos evidência sobre diferenciais de exposição a esse choque da China entre mercados de trabalho locais para estimar seu efeito em indicadores do mercado de trabalho brasileiro, em particular em medidas de desigualdade de rendimentos. Primeiro, encontramos que o choque de demanda por exportações diminuiu a desigualdade de salários no setor de bens comercializáveis, sobretudo por meio do componente entre firmas da dispersão salarial, e apresentamos evidências de que essa redução parece causada por uma mudança no comportamento das firmas, e pode estar relacionado com uma redução no prêmio salarial de firmas exportadoras. Em seguida, estimamos um modelo baseado em Helpman et al. (2016), e exploramos diferenças setoriais no choque de demanda externa para realizar exercícios contrafactuais que corroboram a hipótese de que esse choque pode explicar parte da redução agregada no prêmio salarial de firmas exportadoras e na dispersão de salários. No segundo capítulo, desenvolvemos uma versão do modelo dinâmico de Caliendo et al. (2019) de modo a estimar os efeitos do duplo choque da China na dinâmica setorial do emprego no Brasil. Mostramos que ambos os choques levam à contração da maioria dos setores de manufaturas, e expansão da maioria dos setores de serviços, mas os efeitos de equilíbrio geral dos choques são modestos, especialmente quando comparados a um contrafactual alternativo no qual a produtividade brasileira nos setores primários aumenta. Estendemos o modelo para incluir dois tipos de trabalho, de alta e baixa qualificação; resultados apontam para efeitos distributivos pequenos, mas consistentes com resultados em forma reduzida obtidos no primeiro capítulo. No capítulo final, construímos uma base de dados inédita sobre características de associações setoriais brasileiras, com o intuito de investigar se os setores com maior capacidade de organização política são capazes de obter maior proteção contra competidores estrangeiros. Usamos variação na penetração de importações como uma medida da necessidade de proteção comercial, e para lidar com a endogeneidade nessa medida usamos um instrumento baseado no choque de importações da China. A evidência sugere que setores com maiores sindicatos patronais são capazes de obter maior proteção comercial, em particular por meio de licenciamento não-automático; as estimativas sugerem que esse efeito é mais alto quando a penetração de importações aumenta mais intensamente, o que é interpretado como um aumento na necessidade de medidas de proteção. / [en] This thesis consists of three chapters, all of which focus on the rise of China as a quasi-natural experiment in order to assess the effects of foreign trade shocks on the political economy of trade policy and on the dynamics of labor markets and earnings inequality in Brazil. In the first chapter, we use evidence on the differential exposure across local labor markets to this China shock in order to estimate its effect on Brazilian labor markets outcomes, in particular on measures of income inequality. First, we find that the export demand shock has decreased wage inequality in the tradables sector, mostly through the between-firms component of wage dispersion, and provide evidence that this reduction seems driven by a change in wage-setting behavior of firms, and may be linked to a reduction in the wage premium of exporter firms. We then estimate a model based on Helpman et al. (2016), and explore sectoral differences in the foreign demand shock to run counterfactual exercises that support the hypothesis that this shock can explain part of the aggregate reduction in the exporter wage premium and in wage dispersion. In the second chapter, we develop a version of the dynamic trade model by Caliendo et al. (2019) in order to estimate the effects of the dual China shock on the sectoral dynamics of Brazilian employment. We show that both shocks lead to a contraction in most manufacturing sectors, and an expansion in most services sectors, but the general equilibrium effects of the shocks are modest, especially if compared to an alternative counterfactual in which Brazilian productivity in primary sectors increase. We then extend the model to include two types of labor, skilled and unskilled. Results also point to small distributional effects of the China shock, but consistent with reduced-form evidence obtained in Chapter 1. In the final chapter, we build a novel dataset on Brazilian trade associations’ characteristics in order to investigate whether industries with higher capacity of political organization are able to obtain more protection from foreign competitors. We use variation in import penetration as a measure of the need for trade protection, and address endogeneity on this measure by using an instrumental variables strategy based on the China import shock. Evidence suggests that industries with larger employer unions are able to obtain more protection, particularly through non-automatic licensing; the estimates suggest that this effect is higher when import penetration increases more intensely, which is interpreted as increased need for protective measures.

Mathematical Pluralism: Constructive Mathematics and Economic Theory

Steins, Stefan Arno 09 December 2021 (has links)
Wir schlagen eine praxisorientierte Explikation der philosophischen Position des Mathematischen Pluralismus vor. Dieser Position zufolge existieren mehr als ein legitimes mathematisches System. Wir interpretieren 'legitim' als 'geeignet zur Realisierung wissenschaftlicher Ziele' und wenden die resultierende pluralistische Position auf die Mathematische Ökonomie an. Wir präsentieren ein begriffliches Rahmenwerk, in dem pluralistische Thesen formuliert und evaluiert werden können, stellen ein informelles System der Konstruktiven Mathematik als Alternative zur Klassischen Mathematik vor, und zeigen, dass verschiedene ökonomische Theoreme nicht konstruktiv beweisbar sind. Auf dieser Basis argumentieren wir, dass Pluralismus relativ zu Zielen mit Bezug zu Erklärung und Simplizität in der Ökonomie vorliegt. / We propose a practice-oriented explication of the philosophical position known as mathematical pluralism. According to this position there exist more than one legitimate mathematical system. We interpret 'legitimate' as 'suitable for realizing scientific goals' and apply the resultant pluralist position to mathematical economics. We present a conceptual framework within which pluralist theses can be formulated and evaluated, introduce an informal system of constructive mathematics as an alternative to classical mathematics, and point out that central theorems of economic equilibrium theory are not constructively provable. On this basis, we argue that pluralism obtains with respect to goals related to explanation and simplicity in economics.

中國大陸自「改革開放」以來,在經濟體制和結構上有著急遽的轉變,同時,海峽兩岸的經貿互動與依存程度也愈來愈高。因此,能有效分析中國大陸經濟情勢的政策模型,對於台灣與中國大陸的政策制定者與政策研究分析者而言皆十分重要。可計算一般均衡(Computable General Equilibrium,CGE)模型由於在數據需求的較大彈性及模型結構上的特性,成為中國大陸現今重要的經濟政策模型之一,本研究的目的在於考察、分析中國大陸可計算一般均衡(CGE)模型的研發背景、發展歷程、建模過程、主要政策應用方向及研究結果。   本研究的內容及流程如后:(1)依「歷史研究」、「調查研究」來歸納、分析中國大陸經濟學研究的發展歷程,以及中國大陸可計算一般均衡(CGE)模型的發展歷程;(2)接著依「文獻研究」來分析、分類本研究所蒐集的中國大陸可計算一般均衡(CGE)模型實證文獻(1978年-1998年);(3)接著依「理論研究」來歸納、分析出可計算一般均衡(CGE)模型的發展、基本結構、數據基礎與建模(Modeling);(4)以「可計算一般均衡」(CGE)方法,先依據最新的「1995年度中國投入產出表」,編制出兩張:「中國大陸1995年社會會計矩陣」、「中國大陸1995年金融社會會計矩陣」為模型數據基礎,然後應用中國大陸所研發的兩個可計算一般均衡(CGE)模型(「中國大陸經濟-環境可計算一般均衡模型」、「中國大陸金融可計算一般均衡模型」)的主要結構和方程式,以說明中國大陸可計算一般均衡(CGE)模型的建模過程和政策應用方向及模擬結果。   本研究的研究結果如后:(1)中國大陸經濟學研究的發展、實際經濟情況變化和政策制定需要,導致中國大陸可計算一般均衡(CGE)模型在「改革開放」後的發展可分為「啟蒙研發」和「政策應用」兩個階段;(2)將中國大陸可計算一般均衡(CGE)模型實證文獻(1978年-1998年)有系統地分類出「貿易政策問題」、「能源和環境政策問題」、「財政和稅收問題」、「經濟改革和發展策略問題」、「外來衝擊問題」、「貨幣金融問題」、「社會保險問題」等七類實證文獻;(3)應用兩個中國大陸研發的可計算一般均衡(CGE)模型,來說明建模(Modeling)與數據編制的過程,並延續、拓展相關的政策模擬研究,分析了環境政策(「綠色導向能源政策」,Green-Oriented Energy Policy:2000年-2015年)與匯率政策(「管理浮動匯率政策」,Managed Floating Exchange Rate Policy:1998年)對中國大陸經濟體的影響。 謝 詞 ii 中文提要 iv 英文提要 vi 中文目次 viii 英文目次 ix 表 次 x 圖 次 xi 1. 緒 論 1 1.1 研究動機 1 1.2 研究目的 3 1.3 研究流程與內容 4 2. 文獻探討 5 2.1 中國大陸經濟學研究的發展歷程 5 2.2 中國大陸可計算一般均衡模型的發展 11 2.3 中國大陸可計算一般均衡模型實證文獻回顧 20 3. 可計算一般均衡模型的發展、基本結構、數據基礎與建模 32 3.1 可計算一般均衡模型的概念與發展 32 3.2 可計算一般均衡模型的一般性基本結構 36 3.3 可計算一般均衡模型的數據基礎與校準 40 3.4 可計算一般均衡模型的計算機求解與建模過程 42 4. 中國大陸可計算一般模型之應用(1)─中國大陸經濟-環境可計算一般均衡模型 45 4.1 模型的基本結構 45 4.2 模型方程式 49 4.3 模型的數據基礎與校準 57 4.4 政策應用-中國大陸宏觀調控下環境政策之一般均衡分析 61 5. 中國大陸可計算一般模型之應用(II)─中國大陸金融可計算一般均衡模型 69 5.1 模型的基本結構 69 5.2 模型方程式 71 5.3 模型的數據基礎與校準 73 5.4 政策應用-中國大陸匯率政策之一般均衡分析 78 6. 結 論 83 6.1 本研究主要貢獻 83 6.2 研究限制與建議 84 6.3 後續研究建議 85 參考文獻 86 附錄1. 94 附錄2. 103 / Both the system and structure of Chinese economy have been changed rapidly since the launch of "economic reform and opening to the outside" in Mainland China, and the economic interaction and trade interdependence between Taiwan and Mainland China are intenser and closer. Effective policy analysis models for Chinese economy is very important to the policy makers and policy analysis researcher both in Taiwan and Mainland China. The Computable General Equilibrium (CGE) model has become one of the most important economic policy analysis model because of its characteristic of higher flexibility on benchmark data and structure. The purpose of this study is to review, investigate and analyze the developmental background, developmental progress, modeling procedure, policy simulations and research results.   The brief contents and procedure of this study consist of (1) reviewing on the development of economic research in mainland China and CGE modeling for Chinese economy, (2) reviewing on the literature of CGE models for Chinese economy used on Policy Analysis(1978-1998), (3) reviewing on the development, basic structure, benchmark data and modeling of CGE model, (4) constructing two Chinese Social Accounting Matrix (SAM) tables developed from the most recent 1995 Chinese Input-Output table to be the benchmark data of two CGE models, the "Chinese Economic-Environmental CGE model" and the "Chinese Financial CGE model", which are developed from Chinese government and researchers, and we revise them in this study,(5) applying those two models to show and illustrate the modeling procedure and results of policy simulations of CGE models for Chinese economy.   In conclusion and contribution, it is composed of three parts. (1) The development of CGE model in Mainland China can be divided into two ages, "The Beginning"(1978-1991) and "The Take-off"(1992-), which results from the development of economic research in Mainland China, the rapidly changed economic system and structure of Chinese economy, and government's urgent demands for policy-analysis tools. (2) The literature of CGE models for Chinese economy used on policy analysis from 1978 to 1998 can be classified into seven groups- trade policy, energy and environmental policies, public finance and tax reform policies, economic reform and development strategy, external shocks, monetary and financial policies, and social insurance policy. (3) We apply those two CGE models for Chinese economy to analyze the economic and environmental impacts of environmental policy- " Green-Oriented Energy Policy"(2000-2015) and the economic impacts of the " Managed Floating Exchange Rate Policy"(1998).
