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.

Current Issues in Public Utilities and Public Policy Empirical Studies Focusing on Japan - Original PDF
نویسندگان: خلاصه: Public utility industries are basic to both consumers and firms for main- taining daily life and economic activities. Relevant, practical information based on careful empirical study is necessary to create prudent policy for public utility indus- tries. This chapter summarizes three points: the aim of this book, the characteristics of public industries, and the topic of each chapter. The purpose here is to deepen the general understanding of public utility industries, which, compared with general industries, have distinguishing characteristics such as (i) the necessity for huge infras- tructure networks, (ii) the provision of essential services, (iii) the difficulty of storing services and a peak/off-peak imbalance, (iv) the necessity for a balance of publicness and marketability, (v) the existence of externalities, and (vi) the constraints imposed by public regulation
Sustainable Development Disciplines for Society Breaking Down the 5Ps—People, Planet, Prosperity, Peace, and Partnerships - Original PDF
نویسندگان: خلاصه: Introduction This multidisciplinary book provides 14 problem-solving lectures on the sustainable development of people, peace, planet, and prosperity—four of the five keywords for the Sustainable Development Goals (SDGs), 4 namely people, planet, prosperity, peace, and partnerships (5Ps). According to the Resolution adopted by the General Assembly of the United Nations (2015, p. 2), the SDGs are intended to promote the following actions in these five areas: (1) For people: end poverty and hunger in all their forms and dimensions, as well as ensure that all human beings can fulfill their potential with dignity and equality and in a healthy environment. (2) For planet: protect it from degradation, including through sustainable consumption and production, by sustainably managing natural resources and taking urgent action on climate change, so that it can support the needs of the present and future generations. (3) For prosperity: ensure that all human beings enjoy prosperous and fulfilling lives and that economic, social, and technological progress occurs in harmony with nature. (4) For peace: foster peaceful and inclusive societies that are free from fear and violence. (5) For partnerships: mobilize the means required to implement this agenda through a revitalized Global Partnership for Sustainable Development based on a spirit of strengthened global solidarity, focusing, in partic- ular, on the needs of the poorest and most vulnerable and with the participation of all countries, all stakeholders, and all people
Equity in Health and Health Promotion in Urban Areas Multidisciplinary Interventions at International and National Level - Original PDF
نویسندگان: خلاصه: In the last twenty years, processes of metropolization have seen an uncontrollable increase, registering a rate of global urbanization that—according to the “World Urbanization Prospects 2018” of the United Nations—will reach almost 70% in 2050 [1]. These data, with a global vision, underline the dynamics of the growth of settlements and cities in quantitative, qualitative, historical and social evolution. In poor countries, this growth continues to take place following models of urban aggre- gation that has been unchanged over the years and inadequate to guarantee minimum conditions of health and sanitation. This situation continues to generate a proliferation of informal areas in conditions of extreme poverty and environmental vulnerability. According to a recent UN-Habitat report, which reports how more than a billion people are forced to live in informal settlements and estimates that this number will double by 2030, slums represent a phenomenon destined to define the near futur
Calming the Storms The Carry Trade, the Banking School and British Financial Crises Since 1825 - Original PDF
نویسندگان: خلاصه: But this long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is past the ocean is flat again. —J. M. Keynes, ‘A Tract on Monetary Reform’ in Collected Writings of John Maynard Keynes, IV (Cambridge: CUP, 2013) p. 65.1 The quotation from John Maynard Keynes’ A Tract on Monetary Reform (1923), that ‘in the long run we are all dead’, is probably the most misunderstood in economics. It is often naively assumed to be a carpe diem defence of Keynesian deficit financing during a downturn. That is, ‘care about the recession we’re in now, rather than about the long-term cost of borrowing’; or ‘recklessly enjoy the present and let the future go hang’.2
Seasonal Adjustment Without Revisions A Real-Time Approach - Original PDF
نویسندگان: خلاصه: Preface In the 1980s, the first author was asked for information about profit prospects of a number of companies, in order to predict the change of their prices on the stock market. He looked up annual reports and recent interim results of these companies and noted that interim results consisted largely of a comparison of recent quarterly results to those of the same quarter of the preceding year. Moreover, stock prices reacted instantly to the outcomes of these comparisons. He was struck by the fact that these outcomes were frequently predictable: If there had been an up or down in the preceding year’s quarterly result, this would affect the comparison to the recent quarter. If last year’s ups or downs had been large, such as a profit on the sale of a construc- tion, or a depreciation of goodwill, these would be referred to in the comparison of the present quarterly report and would not come as a surprise and have little or no impact on stock prices. But if the market had become used to rising quarterly profits of Company X to the tune of say 1% over the preceding year, then an increment of ‘only’ 0.5% in the recent quarter would have a negative impact on the stock prices. Yet, this slight reduction in the profit’s increment may have its cause not in the present quarter, but in the preceding year or in the preceding few quarters. But then it is predictable

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 favorableآیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
