Book Description
This doctoral thesis contains three essays on the economics of climate change and the electricity sector. The first essay deals with the subject of greenhouse gas (GHG) emissions and economic growth. The second essay addresses the issues of climate change policies, especially the role of the emergent innovative technologies, and the restructuring of the electricity sector. The third essay presents a model of transmission investments in electric power networks. Chapter One studies the impacts of climate change on economic growth in the world economies. The paper contains explicit formalization of the depletion process of exhaustible fossil fuels and the phase of technology substitution. The impacts of climate change on capital flows and welfare across countries are also investigated. The restructuring of the electricity sector is studied in Chapter Two. It also analyzes how climate change policies can benefit from emergent innovative technologies and how emergent innovative technologies can lower GHG emissions. It is shown that the price of electricity is strictly rising before emergent innovative firms with zero GHG emissions enter the market, but strictly declining as the entry begins. In Chapter Three, a model of electricity transmission investments from the perspective of the regulatory approach is formulated. The Mid-West region of Western Australia, a sub-system of the South West Interconnected System is considered. In contrast with most models in the literature that deal only with network deepening, this model deals with both network deepening and network widening. Moreover, unlike the conventional investment models which are static and deal only with the long run, this model is dynamic and focuses on the timing of the infrastructure investments. The paper is a study of an optimal transmission investment program which is part of the optimal investment program for an integrated model in which investments in transmission and investments in generation are made at the same time.

Book Description
This thesis consists of three chapters on technological innovation as adaptation to climate change. The first chapter adopts a non-cooperative game theory model to investigate the relationship between adaptation technology and the formation of emission-reducing International Environmental Agreements (IEAs) on climate change. The main contribution to the literature consists of considering countries that are heterogeneous with respect to the benefits and costs of both mitigation of emissions and adaptation. While differences in climate vulnerability are a deterrent for cooperation, this chapter shows that increasing the effectiveness of adaptation in highly vulnerable countries can foster an IEA. Both free-riding on climate change mitigation efforts, and free-riding on adaptation technology among members of an IEA can be reduced by the transfer of adaptation technology within the IEA. A numerical example with parameters estimated from climate change data is employed to simulate stable coalitions and demonstrate how the transfer of adaptation technology reduces free-riding on an IEA. The second chapter examines the determinants of adaptive innovation aimed at reducing the impact of natural disasters, which are expected to intensify with climate change. Starting from a conceptual model combining perceived risk theory with innovators' profit motive, this study investigates the salience of innovation induced by natural disasters, using a unique dataset that includes related U.S. patent data, and flood, drought, and earthquake damage data for the years 1977 to 2005. To address the potential endogeneity of disaster damage, the control function approach is employed with instrumental variables constructed from disaster intensity measurements. The results show that impact-reducing innovations at the state level respond to national disaster damages in the U.S. In general, the impact of natural disasters is not localized to a state--that is, disaster damage in a state also stimulates innovations in more-distant states. This is in contrast with comparable existing cross-country evidence. The findings in this paper highlight a policy role for the federal government in more effectively spurring impact-reducing innovations nationwide. With the pressure of economic growth and the impact of climate change, water issues such as water shortage and pollution have substantial impacts on welfare and sustainability. Taking a view of innovation as adaptation to intensified water threats, the third chapter explores the impact of federal and state level regulatory changes with respect to drinking water quality, water pollution and water quantity in the U.S. on the level of relevant technological innovation. Based on a detailed review of relevant legislative acts, a unique dataset covering major amendments and additions to regulated contaminants lists is constructed to capture the changes of water governance in the U.S. in the past 30 years. In addition, technological patents pertaining to water quality and quantity are identified through a comprehensive search process. The empirical results show the impact of water regulations on innovation to be both statistically and economically significant.

Book Description
Chapter 1: The Role of Technological Innovation in Global Climate Policy: In the first chapter, we build a dynamic model of the global economy and climate with three endogenous knowledge stocks. We confirm that the contribution of induced R&D in global climate change is shown to be very sensitive to the elasticity of substitution between energy and other factors of production. Since growth patterns of all types of research depend on whether inputs are gross complements or gross substitutes. Second, the duplication externality. Induced R&D generates a lower abatement cost reduction if we externalize duplication in the business as usual scenario. We exclude duplication in the business as usual scenario since a research institute is based on their contract to do their research. As long as they generate research outputs they would receive payments, they recognize the duplication but they think they will get paid for producing it whether their outputs have been duplicated or not. In reality, agents use too much R&D in the business as usual scenario because they do not take into account the duplication externality. Thus, when the social planner does the optimal scenario, the additional benefits of R&D may not be very much at all. Third, the initial level of research expenditure. Higher initial levels of energy related R&D shares would create a market size effect, leading to an increased contribution of induced R&D. Gerlagh (2008) uses much higher initial energy related shares whereas our research's estimates are much lower, we find this difference would affect the size of the effects of the induced R&D. Fourth, the inter-firm knowledge spillovers. Firms are not successful in capturing all the benefits they create, as many benefits flow out into other firms free of charge. These benefits are called inter-firm knowledge spillovers. Fifth, first-best and second-best policies. The first-best policy fully internalizes the inter-firm knowledge spillovers, which leads to increases in the levels of all types of research whereas the second-best policy does not internalize it, which leads to induced changes in research resulting from the carbon tax affecting pre-existing market distortions. Sixth, a research dividend effect and tax burden effect. The tax may induce an increase in research expenditure, which would increase the welfare and consumption levels. Finally, the results demonstrated that induced R&D has a limited role on the abatement cost reduction of greenhouse gas emissions, overall. Chapter 2: Environmental Policy, Mergers and Environmental R&D with Spillovers: Our research topic is "Environmental Policy, Mergers and Environmental R&D with Spillovers". This project lies at the frontier between environmental economics and industrial organization. We use a duopoly setting of a three-stage game; in the first stage, the government chooses an emission tax and aims for maximizing welfare; in the second stage, firms use R&D to reduce their emissions; in the last stage, firms compete a la Cournot with differentiated products. We focus on two policy regimes and three scenarios, namely regimes of competition and merger and scenarios of commitment, non-commitment, and exogenous tax. The study focuses on two major questions: (1) what is the effect of merger on R&D, and the effect of commitment on R&D? (2) what is the effect of merger and commitment on the economy? Results are obtained through numerical simulations of the model. We find that: (i) Merger has a positive effect on R&D under non-commitment and the exogenous tax scenarios. (ii) Under commitment, if goods are imperfect substitutes or homogenous, merger has a negative effect on R if goods are complements or independent, merger has a positive effect on R&D. (iii) For any types of goods under any regime, commitment has a negative effect on R&D. Chapter 3: Monopoly with Corporate Social Responsibility and Environmental R&D: Our research topic is the effect of the monopolist with corporate social responsibility in the presence of environmental R&D. This project lies at the frontier between environmental economics and industrial organization. We model a monopolist with corporate social responsibility setting in a three-stage game; in the first stage, the regulator determines the emission tax to maximize welfare; in the second stage, the monopolist determines R&D to maximize its objective function; in the third stage, the monopolist determines outputs to maximize its objective function. The study focuses on one major question: under the structure of monopoly with corporate social responsibility, if we change the parameters of R&D technology parameter, the degree of social responsibility, and product differentiation, what are the effects on profit, R&D, environmental damage, consumer surplus, and welfare? We find that: (1) increasing R&D technology parameter enhances welfare in terms of higher consumer surplus and lower damage, while also leading to increases in R&D and decreases in profit; (2) increasing the degree of social responsibility increases R&D and welfare in terms of higher consumer surplus and profit, but also increases the damage; and (3) increasing product differentiation increases profit, R&D, and welfare; it also increases the damage but decreases consumer surplus.

Book Description
In its latest Assessment Report, the Intergovernmental Panel on Climate Change (IPCC, 2007) projects that without further action the global average surface t- perature would rise by a further 1. 8–4. 0°C until the end of this century. But even if the rise in temperature could be limited to the lower end of this range, irreversible and possibly catastrophic changes are likely to occur. Consequently, the protection of the earth’s atmosphere requires substantial efforts to reduce CO and other green- 2 house gas emissions – especially in countries with very high per capita emissions. To limit the imminent rise in temperature, in the Kyoto-Protocol, the European Union has committed itself to reducing the emissions of greenhouse gases by 8% up to 2008–2012 compared to 1990 levels. Within the EU burden sharing agr- ment, some countries have to achieve even higher emissions reductions. Germany was assigned a reduction target of 21%. The entry into force of the Kyoto Protocol in February 2005 marks a first step towards meting global climate targets, but more ambitious action to reduce greenhouse gas emissions is needed after 2012, when the Kyoto targets expire. Under German presidency, the EU has committed itself to unilaterally reduce its greenhouse gas emissions until 2020 by 20%. In case a Post- Kyoto agreement can be reached, the EU reduction target would be 30% (CEU, 2007).
