Asymmetric Information, Corporate Finance, and Investment (National Bureau of Economic Research Project Report)
by R. Glenn HubbardIn this volume, specialists from traditionally separate areas in economics and finance investigate issues at the conjunction of their fields. They argue that financial decisions of the firm can affect real economic activity—and this is true for enough firms and consumers to have significant aggregate economic effects. They demonstrate that important differences—asymmetries—in access to information between "borrowers" and "lenders" ("insiders" and "outsiders") in financial transactions affect investment decisions of firms and the organization of financial markets. The original research emphasizes the role of information problems in explaining empirically important links between internal finance and investment, as well as their role in accounting for observed variations in mechanisms for corporate control.
Asymmetric Jurisdiction Clauses (Oxford Private International Law Series)
by Brooke MarshallAsymmetric jurisdiction clauses, giving one party a right to choose the forum for litigation after a dispute has already arisen, are widespread in international commercial contracting. And yet for close to a decade their enforceability and effects under EU law have been uncertain, with seven different competing decisions from France's highest court progressively contributing to the murky waters. From the interpretation of material changes to the Brussels I Recast Regulation, to obiter comments by English judges as to whether the 2005 Hague Choice of Court Convention on 'exclusive' jurisdiction clauses applies to asymmetric clauses, how can lawyers balance certainty, flexibility, and risk in this difficult legal landscape? This book explores this conundrum and aims to bring clarity to the current law on asymmetric jurisdiction clauses in the EU, England, and Contracting States to the Hague Convention 2005. It seeks to prompt practitioners and scholars to reflect carefully and critically on how and why asymmetric clauses are used, whether courts will -and should- hold businesses to them, and how both the law and the clauses themselves could be better designed in the future.

Asymmetric Kernel Smoothing: Theory and Applications in Economics and Finance (SpringerBriefs in Statistics)
by Masayuki HirukawaThis is the first book to provide an accessible and comprehensive introduction to a newly developed smoothing technique using asymmetric kernel functions. Further, it discusses the statistical properties of estimators and test statistics using asymmetric kernels. The topics addressed include the bias-variance tradeoff, smoothing parameter choices, achieving rate improvements with bias reduction techniques, and estimation with weakly dependent data. Further, the large- and finite-sample properties of estimators and test statistics smoothed by asymmetric kernels are compared with those smoothed by symmetric kernels. Lastly, the book addresses the applications of asymmetric kernel estimation and testing to various forms of nonnegative economic and financial data. Until recently, the most popularly chosen nonparametric methods used symmetric kernel functions to estimate probability density functions of symmetric distributions with unbounded support. Yet many types of economic and financial data are nonnegative and violate the presumed conditions of conventional methods. Examples include incomes, wages, short-term interest rates, and insurance claims. Such observations are often concentrated near the boundary and have long tails with sparse data. Smoothing with asymmetric kernel functions has increasingly gained attention, because the approach successfully addresses the issues arising from distributions that have natural boundaries at the origin and heavy positive skewness. Offering an overview of recently developed kernel methods, complemented by intuitive explanations and mathematical proofs, this book is highly recommended to all readers seeking an in-depth and up-to-date guide to nonparametric estimation methods employing asymmetric kernel smoothing.
Asymmetric Killing: Risk Avoidance, Just War, and the Warrior Ethos
by Neil C. RenicThis book offers an engaging and historically informed account of the moral challenge of radically asymmetric violence — warfare conducted by one party in the near-complete absence of physical risk, across the full scope of a conflict zone. What role does physical risk and material threat play in the justifications for killing in war? And crucially, is there a point at which battlefield violence becomes so one-directional as to undermine the moral basis for its use? In order to answers these questions, Asymmetric Killing delves into the morally contested terrain of the warrior ethos and Just War Tradition, locating the historical and contemporary role of reciprocal risk within both. This book also engages two historical episodes of battlefield asymmetry, military sniping and manned aerial bombing. Both modes of violence generated an imbalance of risk between opponents so profound as to call into question their permissibility. These now-resolved controversies will then be contrasted with the UAV-exclusive violence of the United States, robotic killing conducted in the absence of a significant military ground presence in conflict theatres such as Pakistan, Yemen, and Somalia. As will be revealed, the radical asymmetry of this latter case is distinct, undermining reciprocal risk at the structural level of war. Beyond its more resolvable tension with the warrior ethos, UAV-exclusive violence represents a fundamental challenge to the very coherence of the moral justifications for killing in war.

Asymmetric Monetary Transmission in Europe (European and Transatlantic Studies)
by Volker ClausenThe euro and the ESCB have started in January 1999 and there is naturally a wide-ranging interest in academia and among policymakers in OECD coun tries, how successful European Monetary Union will and can be. EMU has started with 11 countries and experienced a rapid depreciation of the cur rency. With so many EU countries joining for a historical monetary union in a period of economic globalization, international financial market changes and ongoing EU enlargement the problem of monetary policy efficiency becomes crucial; especially as so many countries in the EU still have high unemploy ment rates and the euro has just started at the beginning of a cyclical upswing in the euro zone. Monetary policy is also quite crucial, because the Maastricht convergence criteria severely restrict the scope of national fiscal policy. With a very limited stock of valuable European monetary experience which could be usefully exploited by the ECB and the ESCB respectively, one naturally will appreciate advanced economic modeling of the main issues. This book takes an analytical look at the problem of asymmetric monetary transmission in Euroland. Facing the ECB's monetary policy, individual mem ber countries are likely to experience different policy effects. Countries differ in their financial structure -a well-known argument in the literature -but also in the characteristics of goods and labor markets. The latter fields have been somewhat neglected in the literature but receive broad analytical attention here.
The Asymmetric Nature of Time: Accounting for the Open Future and the Fixed Past (Synthese Library #468)
by Vincent GrandjeanThis open access monograph offers a detailed study and a systematic defense of a key intuition we typically have, as human beings, with respect to the nature of time: the intuition that the future is open, whereas the past is fixed. For example, whereas it seems unsettled whether there will be a fourth world war, it is settled that there was a first world war.The book contributes, in particular, three major and original insights. First, it provides a coherent, non-metaphorical, and metaphysically illuminating elucidation of the intuition. Second, it determines which model of the temporal structure of the world is most appropriate to accommodate the intuition, and settles on a specific version of the Growing Block Theory of time (GBT). Third, it puts forward a naturalistic foundation for GBT, by exploiting recent results of our best physics (viz. General Relativity, Quantum Mechanics, and Quantum Gravity). Three main challenges are addressed: the dismissal of temporal asymmetries as non-fundamental phenomena only (e.g., thermodynamic or causal phenomena), the epistemic objection against GBT, and the apparent tension between GBT and relativistic physics. It is argued that the asymmetry between the open future and the fixed past must be grounded in the temporal structure of the world, and that this is neither precluded by our epistemic device, nor by the latest approaches to Quantum Gravity (e.g., the Causal Set Theory). Aiming at reconciling time as we find it in ordinary experience and time as physics describes it, this innovative book will raise the interest of both academic researchers and graduate students working on the philosophy of time. More generally, it presents contents of interest for all metaphysicians and non-dogmatic philosophers of physics.This is an open access book.
Asymmetric Neighbors and International Relations: Living in the Shadow of Elephants (Routledge Advances in International Relations and Global Politics)
by Ian Roberge Nara Park Thomas R. KlassenWith a range of case studies from every continent, the contributors to this book analyze the challenges that arise for states living with much larger neighbors, and the policies they develop to account for this asymmetry. Bringing together the perspectives of bilateral relations and the study of small states, this book analyzes a range of scenarios where one or more smaller countries must manage relations with a much larger neighbor or neighbors, from the perspective of the smaller countries. Each case presents different priorities, depending on the relationship between the states concerned, while highlighting the commonalities across the various scenarios. The range of cases and contributors is wide and diverse, with examples including Togo’s relationship with Ghana, Mongolia’s with China, and Colombia’s with Brazil – as well as more widely known examples such as Canada and the United States, or Australia and New Zealand. A valuable resource for scholars and students of international relations, and public policy of small- and medium-sized states.

Asymmetric Organocatalysis: From Biomimetic Concepts to Applications in Asymmetric Synthesis
by Albrecht Berkessel Harald GrögerAsymmetric catalysis represents still one of the major challenges in modern organic chemistry. Besides the well-established asymmetric metal-complex-catalysed syntheses and biocatalysis, the use of "pure" organic catalysts turned out to be an additional efficient tool for the synthesis of chiral building blocks. In this handbook, the experienced authors from academia and industry provide the first overview of the important use of such metal-free organic catalysts in organic chemistry. With its comprehensive description of numerous reaction types, e.g., nucleophilic substitution and addition reactions as well as cycloadditions and redox reactions, this book targets organic chemists working in industry and academia, and deserves a place in every laboratory.
Asymmetric Organocatalysis: Lewis Base And Acid Catalysts (Topics in Current Chemistry #291)
by Benjamin ListAs nucleophiles, simple alkenes are typically so unreactive that only highly active electrophiles, such as carbocations, peroxides, and halogens will react with them. For the generation of carbon-carbon bonds, milder methods will often be required. Fortunately, it is possible to increase the reactivity of alkene-type p-nucleophiles by introducing electron-donating substituents. Substitution of one H with an OH or OR gives an enol or a vinyl ether, which are already much better nucleophiles. Using nitrogen instead of oxygen, one obtains even better nucleophiles, enamines. Enamines are among the most reactive neutral carbon nucleophiles, exhibiting rates that are even comparable to some charged nucleophiles, such as enolates [1, 2]. Most enamines, unfortunately, are sensitive to hydrolysis.
Asymmetric Organocatalysis Combined with Metal Catalysis (Topics in Current Chemistry Collections)
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience.Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.The chapter "Enamine/Transition Metal Combined Catalysis: Catalytic Transformations Involving Organometallic Electrophilic Intermediates" is available open access under a CC BY 4.0 License via link.springer.com.

Asymmetric Passive Components in Microwave Integrated Circuits (Wiley Series in Microwave and Optical Engineering #182)
by Hee-Ran AhnThis book examines the new and important technology of asymmetric passive components for miniaturized microwave passive circuits. The asymmetric design methods and ideas set forth by the author are groundbreaking and have not been treated in previous works. Readers discover how these design methods reduce the circuit size of microwave integrated circuits and are also critical to reducing the cost of equipment such as cellular phones, radars, antennas, automobiles, and robots. An introductory chapter on the history of asymmetric passive components, which began with asymmetric ring hybrids first described by the author, sets the background for the book. It lays a solid foundation with a chapter examining microwave circuit parameters such as scattering, ABCD, impedance, admittance, and image. A valuable feature of this chapter is a conversion table between the various circuit matrices characterizing two-port networks terminated in arbitrary impedances. The correct conversion has also never been treated in previous works. Next, the author sets forth a thorough treatment of asymmetric passive component design, which covers the basic and indispensable elements for integration with other active or passive devices, including: * Asymmetric ring hybrids * Asymmetric branch-line hybrids * Asymmetric three-port power dividers and N-way power dividers * Asymmetric ring hybrid phase shifters and attenuators * Asymmetric ring filters and asymmetric impedance transformers With its focus on the principles of circuit element design, this is a must-have graduate-level textbook for students in microwave engineering, as well as a reference for design engineers who want to learn the new and powerful design method for asymmetric passive components.

Asymmetric Politics: Ideological Republicans and Group Interest Democrats
by Matt Grossmann David A. HopkinsWhy do Republican politicians promise to rein in government, only to face repeated rebellions from Republican voters and media critics for betraying their principles? Why do Democratic politicians propose an array of different policies to match the diversity of their supporters, only to become mired in stark demographic divisions over issue priorities? In short, why do the two parties act so differently-whether in the electorate, on the campaign trail, or in public office? Asymmetric Politics offers a comprehensive explanation: The Republican Party is the vehicle of an ideological movement while the Democratic Party is a coalition of social groups. Republican leaders prize conservatism and attract support by pledging loyalty to broad values. Democratic leaders instead seek concrete government action, appealing to voters' group identities and interests by endorsing specific policies. This fresh and comprehensive investigation reveals how Democrats and Republicans think differently about politics, rely on distinct sources of information, argue past one another, and pursue divergent goals in government. It provides a rigorous new understanding of contemporary polarization and governing dysfunction while demonstrating how longstanding features of American politics and public policy reflect our asymmetric party system.
