    <description>Title: Essays in macroeconomics: Inflation inequality, consumption baskets and impulse responses
Authors: Weissert, Christoffer Jessen
Abstract: The dissertation consists of three self-contained chapters on topics within macroeconomics. All chapters share an orientation towards empirical analysis of macroeconomic questions. New methods for empirical analysis are presented in the first and third chapter. The method presented in the first chapter contributes to analyses of inflation inequality. The method presented in the third chapter contributes to analyses on how the economy responds to shocks. The inflation inequality discussed in the first chapter relates to households' consumption behavior. In the first and second chapter specific empirical analyses on US households' consumption behavior is conducted.</description>

    <description>Title: Essays on financial transaction taxes: Impact on trading volume, market composition and liquidity
Authors: Thöni, Patrick
Abstract: Financial Markets have undoubtedly played a crucial role in the economic development and technological growth the world has experienced over the last century. The availability of liquid markets greatly facilitates the opportunities of raising capital and risk sharing, allowing the financing of large-scale real enterprises. Additionally, it enables savers to increase their returns while diversifying their risk. On the other hand, liquid markets also allow for speculative trading, which ultimately can lead to a misallocation of resources. This fundamental trade-off is what lies at the core of the original idea of a financial transaction tax (FTT). While proponents of FTTs highlight their potential to curb speculation driven by short term incentives, opponents argue that it would harm market quality by decreasing overall liquidity, interfering with price discovery and raising the cost of capital. This thesis furthers the existing body of work on this key tension surrounding FTTs from a financial microstructure perspective. By means of both theoretical and empirical analysis, the three self-contained chapters presented in this dissertation investigate the impact of FTTs on trading volume and migration, trader composition and ultimately market quality.</description>

    <description>Title: Technology and the environment in general equilibrium
Authors: Berg, Rasmus Kehlet
Abstract: The PhD dissertation consists of three self-contained parts that deal with representing technology in environmental economic models. All three parts offer ways for improving economic models by leveraging knowledge on technologies collected by other academic disciplines. The first two parts explore new ways for economic models to capture the potential for renewable energy technologies. One of the main challenges of reaching net-zero greenhouse gas emissions is that most cheap, renewable energy generation is intermittent; the availability of wind or solar power depends on natural conditions, such as wind speed and cloud cover. We develop a technology-rich model for electricity and district heat systems and show that it captures the key effects of intermittency. We show that the model can be solved efficiently alongside conventional economic models using smoothing techniques. This integrated framework can be used to evaluate policies e.g. aimed at lowering emissions through electrification of polluting economic activity, such as transportation, using intermittent renewable energy. The problem of intermittency can be solved using a combination of four technologies: Back-up capacity of more flexible dispatchable electricity producing plants, expansion of the transmission grid to enable more trade in electricity, flexible demand technologies, and electricity storage. The second part of the dissertation uses the technology-rich model from part one to investigate the value and potential of electricity storage. We show that in the Danish context, investing in electricity storage reduces greenhouse gas emissions and lowers average prices significantly. However, the investment costs of lithium-ion batteries prohibit them from being cost-effective until after 2030. We show that this is largely a result of neighboring countries' strategy for investments in storage technologies and intermittent renewables, thus emphasizing the importance of a technology-rich model that includes details on the transmission grid. Finally, while parts one and two focus on the scope for emission reductions through renewable energy, part three focuses on modeling reductions through abatement technologies. We provide a novel framework that allows us to use much more detailed data on abatement technologies than state of the art environmental economic models. We show under what conditions current best practices over- and underestimates abatement costs when technology data is not appropriately represented in the economic model.</description>

    <description>Title: Essays on health care: New insights into the economic burden of population ageing and the implementation of health policies aimed at promoting evidence-based clinical practice and consistency in the delivery of hospital care
Authors: Iversen, Anna Kollerup
Abstract: This thesis consists of three self-contained chapters. Each chapter casts light on different aspects of the challenges that national health authorities face in providing universal health care coverage under resource constraints and under the continual introduction of new knowledge and new expensive medical advances. To inform the debate on the future economic burden of population ageing and possible threats to the sustainability of universal health care coverage, the first chapter examines static and dynamic properties of the past decade's health care expenditure patterns across age, disease groups and time in Denmark. The second and third chapters examine the implementation of two evidence-based health policies, namely the implementation of national clinical practice guidelines and a regulation of the supply of hospital care by centralization to fewer and larger clinical facilities. The policies had the common goal of promoting evidencebased clinical practice and procedures in hospital care by mitigating slow adoption of new knowledge and reducing variation in the adoption of new medical advances, routines and procedures. The second chapter analyzes the effects of centralizing breast cancer care to fewer high-volume clinics on both cost-saving metrics and the quality of care that closure-affected patients receive. The third chapter explores whether consistency in the delivery of health care is achieved when introducing a new treatment with both national clinical guidelines and care centralization.</description>
