The Colombian Economy and Its Regional Structural Challenges A Linkages Approach - Original PDF
نویسندگان: خلاصه: Preface I have been teaching a Ph.D. course on “Applied General Equilibrium Models” at the University of São Paulo, Department of Economics, since 1999. Over the last editions of the course, the material was built around specific countries or regions, selected to be the object of modeling practices undertaken by the students. This praxis turned out to be very rewarding for the students since they were motivated to apply different techniques to study concrete problems in a common economic system. Throughout this process, they had the opportunity to collaborate among themselves and interact with scholars from the study regions, often generating scholarly publications. We had already worked with countries such as Brazil, Chile, Greece, and Paraguay, and with different regional contexts, especially within Brazil. Colombia had always been a top candidate to receive our attention. Our previous engagement with colleagues from the Centro de Estudios Económicos Regionales (CEER), a research center specialized in Regional and Urban Economics at the Banco de la República— the Colombian Central Bank—provided a unique opportunity to develop a special edition of the course on the country. During a visit to Cartagena in 2019, Jaime Bonet and I finally agreed to use Colombia as the case study in the forthcoming edition of the course. We designed the Colombian edition in innovative and challenging ways, raising the bar for the expected outcomes, including a workshop to be hosted in Cartagena in 20201 and the publication of a volume including the contributions by different authors forming a cohesive unit. We built the activities upon solid co
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

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
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.
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
Modern Cryptography Volume 2 A Classical Introduction to Informational and Mathematical Principle - Original PDF
نویسندگان: خلاصه: Preface For integer factorization and discrete logarithm calculation, P.W.Shor published an effective quantum calculation in SIAM Journal on Computing in 1997, which is called the Shor algorithm in academic circles. Classical public key cryptosystems such as RSA, ECC and so on could not resist the attack of the Shor algorithm, so the major security risks of public key cryptosystems are completely exposed to the Shor algorithm and quantum computer. In the past 20 years, the rise and development of post-quantum cryptography have close relation with the lattice cryptosystems. The academic community believes that the hard problems on lattice, such as the shortest vector problem (SVP), the continuous shortest vector problem (SIVP) and the determination of the shortest vector problem (GapSVP) can resist quantum computing effectively, so the public key cryptosystems based on the hard problems on lattice become the core theory and technology of the post-quantum cryptography. At present, there are six kinds of published post-quantum cryptosystems: 1. Ajtai-Dwork cryptosystem (1997). Ajtai constructed a collision-resistant Hash function by the circulant matrix and ideal matrix, and converted the collision point into the shortest vector problem on q-ary integer lattice. Ajtai first proposed the concept of random lattice (Gauss lattice) in 1996, and established the famous reduction principle ‘from the worst case to the average case’. The security of Ajtai-Dwork cryptosystem could be fully proved by this reduction principle. 2. GGH/HNF cryptosystem (1997). In 1997, Goldereich, Goldwasser and Halevi constructed a public key cryptosystem based on the closest vector problem on the q-ary integer lattice, which was further improved by Micciancio using the Hermite normal basis in 2005. The idea of Micciancio is very simple. Since the HNF basis of any lattice can be easily computed from its generated matrix, the GGH cryptosystem uses the HNF basis as the public key directly. 3. NTRU cryptosystem (1998). Number Theory Research Unit (NTRU) is a quantum-resistant computing public key cryptosystem developed by J. Hoffstein, J. Pipher and J. H. Silverman in Brown University in 1998, which has become the most attractive post-quantum cryptosystem due to its simple algorithm, fas
