Global Economic Challenges 6th International Conference on Banking and Finance Perspectives, Cuenca, Spain - Original PDF
نویسندگان: خلاصه: Price movements in the energy market are crucial because energy plays a vital role in the world’s economies and human life. The high volatility in energy prices since the 1990s is due to several historical developments, including the deregulation of energy markets, the Asian financial crisis in 1997, and the 2008 global financial crisis (Lien et al., 2016; Lang & Auer, 2019) have increased the need for an appro- priate protection strategy. Hedging by using futures contracts makes the problem of “finding an appropriate hedge ratio” vital. In calculating the optimal hedge ratio (OHR), estimations are mostly based on the average (expected) relationship between spot and futures prices. This approach ignores the tail distribution of the variables (Lien et al., 2016; Shrestha et al., 2018). However, the widely documented non- normal distribution of financial variables makes considering the quantiles of the variables essential. To fill this gap, we used the recently developed quantile-on- quantile (Q-Q) (Sim & Zhou, 2015) approach to estimate the minimum-variance (MV) hedge ratio for crude oil, natural gas, and gasoline markets. Besides, to have a better understanding of the relationship between these variables, we examined long-run and causal relationships by using methods that consider the distribution of the variables.
Environmental Regulations and Industrial Competitiveness Case Studies of Toxic Industries in Southern California - Original PDF
نویسندگان: خلاصه: 1 Chapter 1 Environmental Regulations and Industrial Competitiveness Abstract Industries in the U.S. emit billions of pounds of toxic chemicals into the environment every year, resulting in a major risk to human health. Many economists and policy makers, however, are strongly opposed to environmental regulations based on an assumption that regulations lead to a loss of jobs and a declining stan- dard of living for U.S. citizens. The empirical literature on this question has pro- duced mixed results, and this chapter critically assesses several conceptual and methodological issues that are embedded in this literature. Our thesis is that strin- gent environmental regulations have the potential to effectively and efficiently reduce toxic emissions from polluting firms and industries while having a negligible impact on the economic competitiveness of firms and industries. We investigate this thesis through three empirical case studies of polluting industries in Southern California that are highly regulated by the South Coast Air Quality Management District (AQMD): metal finishing, wood furniture, and dry cleaning. We also attempt to reveal the institutional process by which firms comply with environmen- tal regulations. Keywords Environmental regulations · Economic competitiveness · Environmental pollution · Economic externalities · Market failure · Environmental compliance · Technological uncertainty · Innovation · Adoption Introduction Over the last half century, the US federal government has played an active role in regulating the emission of toxic chemicals from polluting firms and industries (Rosenbaum, 2019; Telsey, 2016). Congress passed the Clean Air Act of 1970 “to protect and enhance the quality of the nation’s air resources so as to promote the public health and welfare and the productive capacity of the population” (US Environmental Protection Agency, 2007, p. 2). Congress also created the EPA (Environmental Protection Agency) in 1970 to implement and enforce the nation’s environmental law
Healthcare and Disease Burden in Africa The Impact of Socioeconomic Factors on Public Health - Original PDF
نویسندگان: خلاصه: Chapter 1 Introduction There is an acute scarcity of research and studies on the conditions of healthcare in African countries. According to Marincola and Kariuki (2020), 20% of the global disease burden falls on the shoulders of Africa, yet only 1% of worldwide scientific output focuses on African countries. Filling the epistemological gap is critical, for it will not only shine a light on our understanding of the realities of the continent, but also pave way for more engaged future studies. The investigation of existing health- care conditions in Africa provides an indispensable basis for generating educated responses to the challenges that confront the continent as a whole and across its different localities. Africa also occupies a historically overlooked and underrep- resented position. It is a unique continent with highly diverse cultures, societies, and economic compositions. While significantly different from the Western or more economically developed parts of the world, Africa is playing a crucial role on the global stage in a variety of aspects. Therefore, studies of Africa will not only benefit the regional communities, but also have a long-lasting impact on the rest of the world. Africa carries the oldest and most diverse genome. Around seven billion of the world’s population share a common origin in Africa. The burden of disease in Africa is also shifting from communicable to non-communicable diseases, which is also a major concern of the societies that are more economically developed. Therefore, addressing the disease burden in Africa, in parallel, means investing in the prevention and treatment of diseases in the rest of the world.
Default Nudges by Patrik Michaelsen · Cass R. Sunstein - Original PDF
نویسندگان: خلاصه: Abstract One of the most widely used nudges, and one of the most effective, is the default rule. A default rule works by designating one course of action as the default; it establishes what will happen unless the decision-maker actively makes a change. Why are defaults so effective, in areas that include savings, health care, and air pollution? The answer is that they tap into at least three different psychological mechanisms. On a policy level, defaults, like other nudge interventions, typically benefit from being cheap and easy to implement, resulting in a highly cost-effective way of inducing behavior change. This has made nudging a popular tool for businesses and government
Pandemic and the City - Original PDF
نویسندگان: خلاصه: The recent COVID-19 experience has left deep traces in the urban fabric and has prompted a re-orientation regarding the future of cities. Is an urban overhaul on the way? And will digital technology erode conventional urban agglomeration advan- tages? The socioeconomic impacts of the pandemic will definitely leave their mark on cities. For example, the digital divide has already become more apparent regarding equitable access to education or to virtual libraries. Furthermore, climate change will have a stronger influence on cities than in the past, given that avoiding close indoor activities or reducing dense concentrations of people may become commonplace. For example, operating restaurants with outside dining areas or organizing open-air activities which allow safe social distancing will face new challenges in cities, in particular in places where weather conditions may become less favorable
Global Cooperation and G20 Role of Finance Track - Original PDF
نویسندگان: خلاصه: The realisation that emerging economies were becoming systematically important dawned on the major advanced economies with the Asian and Russian financial crises of the late 1990s, and hence, the necessity was felt for a larger forum than the G7 encompassing the emerging economies. The Group of Twenty Countries (G20) was launched as a forum of the finance ministers and Central Bank governors primarily to address the challenges to international financial stability that had begun in Asia in 1997. The need was felt for a “permanent forum” for informal dialogue between developing and developed countries in the G20. The need for the inclusion of major emerging economies in discussions on the international financial system was underlined by the global financial crisis of 2008. A platform was created where leaders of systemically important countries resolved to coordinate macroeconomic policies to counteract the global financial crisis. In turn, they analysed the deeper, underlying causes of the financial crisis. This chapter introduces and motivates the book and discusses the rationale behind the formation of the G20. It discusses the background of the G20, the role of G7 and G8, and discusses the organisation of the book in the chapters that follow
Disaster Management and Information Technology Professional Response and Recovery Management in the Age of Disasters - Original PDF
نویسندگان: خلاصه: There is no one single journey when it comes to technology. For those who did not grow up as “digital natives” each has taken their own path in accepting, developing technological skills and expanding them by integrating them into their everyday work environment. Indeed, the journey continues with no hard- set destination before us. We only know that technological development and use of technology continue to expand exponentially with each passing day. What follows is therefore just one American perspective on how the profession of emergency management has adopted technologies over the decades in which the profession has existed. All the while, working daily to plan for, train, and practice for future emergency and disaster response events that are sure to come.
HCI International 2022 – Late Breaking Posters - Original PDF
نویسندگان: خلاصه: 4 P. Asghari et al. 1 Introduction Eye tracking (ET) is frequently used, for example, in behavioral research and human-computer interaction. Eye movement patterns can reveal detailed infor- mation about the user’s cognitive processes, their attention level, or decision- making processes [3,12]. Applications and research based on ET require reliable and robust data [9]. Traditionally, this requires dedicated hardware with high- resolution cameras and infrared illumination to detect corneal reflections [7]. However, dedicated hardware is expensive and thus limits the pervasive use in real-world applications. This situation may change since, propelled by recent advances in deep learning, appearance-based gaze estimation methods that deliver promising results based on low-cost consumer-grade camera inputs start to emerge [2,10,11,21]. These approaches learn to estimate gazes from a video stream based on large-scale data sets and provide 3D gaze vectors or correspond- ing 2D gaze locations on a screen. Furthermore, they do not require any specific external devices and can be used with standalone computers, laptop built-in webcams, or mobile device consumer-grade cameras. This opens up the possi- bility of developing affordable automated intelligent ET solutions for research, commerce, and the general public. On the way to realize this ambition, webcam ET (wcET) has to address several challenges including gaze estimation accu- racy, gaze estimator prediction time, and that gaze estimation quality can be affected by user movements [11]. This paper aims to contribute to the first step toward utilizing wcET as a low-cost pervasive technology by validating the data quality of a state-of-the-art wcET approach in comparison to the performance of an established, commercially available dedicated eye tracking (dhET) system. Accordingly, we address the following research question in our work: How does the gaze estimates of wcET differ from dhET in practical settings regarding accu- racy, precision, and sampling rate? We will further discuss how the limitations of the data quality may affect the performance of wcET applications
