Grounded in literature from the sociology of finance and international political economy, and informed by extensive empirical research, The Everyday Life of Global Finance explores the unprecedented relationships that now bind Anglo-American society with the financial markets. As mutual funds have increased in popularity and pension provision has been transformed, many more individuals and households have come to invest in stocks and shares. As consumer borrowing has risen dramatically and mortgage finance has embraced those deemed sub-prime, so the repayments of credit card holders and mortgagors have provided the basis for the issue and trading of bonds and other market instruments.
The Everyday Life of Global Finance is an ambitious and innovative contribution to our understanding of the contemporary financial world. It shows how financial market networks have come to extend well beyond Wall Street and the City of London, becoming embedded and embodied in routine saving and borrowing in the US and UK. Society's new-found relationships with the markets are also shown, however, to be marked by stark inequalities, manifest contradictions, and political dissent.

This book focuses on aspects of Industrial Mathematics (Networks; Complex Systems and Behavioral Game Theory) and Theoretical Computer Science (Behavioral Game Theory and Applied Math). Its major contribution is that it introduces new models and "informal" algorithms that solve social-choice problems (using behavioral Game Theory), it introduces new mathematical proofs, and it introduces new algorithms that prove that the Myerson-Satterthwaite Impossibility Theorem is wrong or inapplicable. The Myerson-Satterthwaite Impossibility Theorem has been a major foundation theorem in various branches of Computer Science and Applied Math. The book analyzes Industrial Organization, Mechanism Design, Political Economy and Complex Systems issues in the global accounting/consulting industry, the "Quasi-franchising industry" and the global Credit Rating Agency (CRA) industry which are currently some of the most international of all services industries, and have or can have substantial effects on international trade and international capital flows. During 2000-2019, the services sector in general expanded in many countries and especially in emerging markets countries - and that is having substantial effects on the evolution of national economies. The objectives and achievements of this book are multifaceted. It explains the macroeconomic, behavioral operations research and political economy issues that affect and the evolution of accounting/auditing firms, CRAs, management consulting firms and environmental auditing firms. It also analyzes the types of intra-company decisions and group dynamics and auditor-decisions that can have significant effects on innovation and competition within the accounting/consulting industry and (on clients' industries) and on overall economic growth in nations. Furthermore, it analyzes structural changes and antitrust problems in the global accounting/consulting industry and the CRA industry and explains how these antitrust problems and structural changes have worsened climate change and corporate compliance with environmental regulations. Among these topics the author also talks about issues that affect audit contract, contracting between CRAs and issuers, and industry structure and evolution by critiquing various existing CRA business models and introducing new business models for the future.

The idea that each country should have one currency is so deeply rooted in people's minds that the possibility of multiple and concurrent currencies seems unthinkable. Monetary systems contribute to problems of high unemployment and social distress during financial and economic crisis, so reforms to increase the responsiveness and flexibility of the monetary system can be part of the solution. This book discusses 'monetary plurality', which is the circulation of several currencies at the same time and space. It addresses how multiple currency circuits work together and transform socio-economic systems, particularly by supporting economies at the local level of regions and cities. The book shows that monetary plurality has been ubiquitous throughout history and persists at present because the existence of several currency circuits facilitates small-scale production and trade in a way that no single currency can accomplish on its own. Monetary plurality can improve resilience, access to livelihoods and economic sustainability. At the same time, it introduces new risks in terms of economic governance, so it needs to be properly understood. The book analyses experiences of monetary plurality in Europe, Japan, and North and South America, written by researchers from East and West and from the global North and South. Replete with case studies, this book will prove a valuable addition to any student or practitioner's bookshelf.

Credit and Community examines the history of consumer credit and debt in working class communities. Concentrating on forms of credit that were traditionally very dependent on personal relationships and social networks, such as mail-order catalogues and co-operatives, it demonstrates how community-based arrangements declined as more impersonal forms of borrowing emerged during the twentieth century.
Tallymen and check traders moved into doorstep money-lending during the 1960s, but in subsequent decades the loss of their best working class customers, owing to increased spending power and the emergence of a broader range of credit alternatives, forced them to focus on the 'financially excluded'. This 'sub-prime' market was open for exploitation by unlicensed lenders, and Sean O'Connell offers the first detailed historical investigation of illegal money-lending in the UK, encompassing the 'she usurers' of Edwardian Liverpool and the violent loan sharks of Blair's Britain.
O'Connell contrasts such commercial forms of credit with formal and informal co-operative alternatives, such as "diddlum clubs," "partners," and mutuality clubs. He provides the first history of the UK credit unions, revealing the importance of Irish and Caribbean immigrant volunteers, and explains the relative failure of the movement compared with Ireland.
Drawing on a wide range of neglected sources, including the archives of consumer credit companies, the records of the co-operative and credit union movements, and government papers, Credit and Community makes a strong contribution to historical understandings of credit and debt. Oral history testimony from both sides of the credit divide is used totelling effect, offering key insights into the complex nature of the relationship between borrowers and lenders.

Moving Beyond Modern Portfolio Theory: Investing That Matters tells the story of how Modern Portfolio Theory (MPT) revolutionized the investing world and the real economy, but is now showing its age. MPT has no mechanism to understand its impacts on the environmental, social and financial systems, nor any tools for investors to mitigate the havoc that systemic risks can wreck on their portfolios. It's time for MPT to evolve. The authors propose a new imperative to improve finance's ability to fulfil its twin main purposes: providing adequate returns to individuals and directing capital to where it is needed in the economy. They show how some of the largest investors in the world focus not on picking stocks, but on mitigating systemic risks, such as climate change and a lack of gender diversity, so as to improve the risk/return of the market as a whole, despite current theory saying that should be impossible. "Moving beyond MPT" recognizes the complex relations between investing and the systems on which capital markets rely, "Investing that matters" embraces MPT's focus on diversification and risk adjusted return, but understands them in the context of the real economy and the total return needs of investors. Whether an investor, an MBA student, a Finance Professor or a sustainability professional, Moving Beyond Modern Portfolio Theory: Investing That Matters is thought-provoking and relevant. Its bold critique shows how the real world already is moving beyond investing orthodoxy.

Businesses take on many forms ranging from sole proprietorships, partnerships, and close corporations to companies. The ability of these forms of business ownership to obtain and service credit depends not only on their financial circumstances, but also the knowledge and ability of the credit provider to assess the business' creditworthiness. For a business to be successful it must make a profit. The profit on a sale is not earned unless the money for the sale is in the bank on due date. It is also true that the longer it takes to collect the money from a debtor, the more difficult it becomes. Applied credit management teaches the learner all aspects of the credit management function of an organisation, from the evaluation of the new application, the investigation of the creditworthiness of the customer, the final approval or rejection to the collection and ultimate litigation of an account. All aspects of the National Credit Act (Act 34 of 2006) have been incorporated in the principles of this book.

This book delves into the essential concepts and technologies of acquiring systems. It fills the gap left by manuals and standards and provides practical knowledge and insight that allow engineers to navigate systems as well as the massive tomes containing standards and manuals. Dedicated to card acquiring exclusively, the book covers: Payment cards and protocols EMV contact chip and contactless transactions Disputes, arbitration, and compliance Data security standards in the payment card industry Validation algorithms Code tables Basic cryptography Pin block formats and algorithms When necessary the book discusses issuer-side features or standards insomuch as they are required for the sake of completeness. For example, protocols such as EMV 3-D Secure are not covered to the last exhaustive detail. Instead, this book provides an overview, justification, and logic behind each message of the protocol and leaves the task of listing all fields and their formats to the standard document itself. The chapter on EMV contact transactions is comprehensive to fully explain this complex topic in order to provide a basis for understanding EMV contactless transaction. A guide to behind-the-scenes business processes, relevant industry standards, best practices, and cryptographic algorithms, Acquiring Card Payments covers the essentials so readers can master the standards and latest developments of card payment systems and technology

This title deals with the three important branches of the law relating to security. Within a small compass it analyses in critical detail the governing rules. In particular, it is a practical guide to current practice.

The formation and management of capital are among the central issues in economic growth, especially in 'under-developed' countries, and form the main theme in this volume. The societies examined vary widely, both geographically and also in terms of types of social and economic structures. First published in 1964.

Providing the poor with access to financial services is one of many ways to help increase their incomes and productivity. In many countries, however, traditional financial institutions have failed to provide this service. Microcredit and co-operative programmes have been developed to fill this gap. Their purpose is to help the poor become self-employed and thus escape poverty. Many of these programmes provide credit using social mechanisms, such as group-based lending, to reach the poor and other clients, including women, who lack access to formal financial institutions. With increasing assistance from the World Bank and other donors, microfinance is emerging as an instrument for reducing poverty and improving the poor's access to financial services in low-income countries. This book examines the experiences of the Grameen Bank and two other major microcredit programs in Bangladesh in order to quantify the potential and limitations of microcredit programmes as an instrument for reducing poverty and delivering financial sevices to the poor.

Indonesia is the most populous Muslim country in the world. Taking into account also its endowment and potential economic resources, the Islamic banking industry in Indonesia was expected to take on an important role in facilitating more financial resources and to contribute to the internationalization of the Islamic mode of financing particularly in the Asia-Pacific region. However, the reality is far from the expectation. This book aims to clarify the causes and fundamental constraints leading to the extraordinarily low level of Indonesia's Islamic financial deepening. The authors draw on the traditions of Institutional Economics which are concerned with the rules or mechanisms of creating the 'incentive' and 'threat' for economic players because the rules (institutions) would matter as the determinant for economic development and economic efficiency. This book offers a fairly new analytical lens by hypothesizing that Islamic banks must earn additional profit- the authors coined as 'Islamic bank rent' - to maintain their franchise value as prudent Shari'ah-compliant lenders when compared to conventional banks. The authors argued that insufficient provision of the Islamic bank rent opportunity may have caused the Indonesia's Islamic banks the opportunity to learn and improve their skill and capacity for the credit risk management. The book also offers evidence in support of implementing economic and affirmative policy necessary for incubating and developing the Islamic banking industry in Indonesia and making Indonesia an international Islamic financial hub in the Asia-Pacific region. This book will be a useful resource for policy makers and researchers interested in Islamic banking in Indonesia.

In the seventeenth century, England saw Holland as an economic power to learn from and compete with. English Economic Thought in the Seventeenth Century: Rejecting the Dutch Model analyses English economic discourse during this period, and explores the ways in which England's economy was shaped by the example of its Dutch rival. Drawing on an impressive range of primary and secondary sources, the chapters explore four key areas of controversy in order to illuminate the development of English economic thought at this time. These areas include: the herring industry; the setting of interest rates; banking and funds; and land registration and credit. The links between each of these debates are highlighted, and attention is also given to the broader issues of international trade, social reform and credit. This book is of strong interest to advanced students and researchers of the history of economic thought, economic history and intellectual history.

Both studies of political power and Europeanization studies have tended to neglect central banks. As the age of the euro reaches its 10th anniversary, it is timely to reflect on what it means for central banks, which have been at the forefront of the establishment of Economic and Monetary Union in the European Union. Central banks have been caught up in a major historic political project. What does it mean for them? What does the age of the euro tell us about the power of central banks, their Europeanization and whether they are coming to resemble each other more closely?
This book brings together a range of recognized academic specialists to examine the main political aspects of this question. How, and in what ways, has the euro Europeanized central banks (members and non-members of the Euro Area)? What have been its effects on the power of central banks and their use of power? Has the euro generated convergence or divergence in central banking? The book offers the first, in-depth and systematic political analysis of central banks in the first decade of the euro. It places the euro in its global and European contexts, including the US Fed and the Australasian central banks, patterns of differentiated integration in European central banking, and the European Central Bank. It offers a set of case studies of its effects on a representative sample of EU central banks (euro 'insiders' and 'outsiders') and looks at four main thematic areas (monetary policy, financial market supervision, accountability and transparency, and research).
The book contributes to Europeanization studies, comparative political economy, and studies of Economic and Monetary Union. It will be of major interest to students of the European Union and European integration, comparative European politics, and area and 'country' studies. More generally, it will interest all those interested in central banking and their pivotal and problematic position between politics and markets.

Walter Bagehot noticed once that "John Bull can stand many things, but he cannot stand two per cent." Well, for several years, he has had to stand interest rates well below that, in some countries even below zero. However, despite this sacrifice, the economic recovery from the Great Recession has been disappointingly weak. This book's aim is to answer this question. The central thesis of the book is that the standard understanding of the monetary transmission mechanism is flawed. That understanding adopts erroneous assumptions-such as, that low interest rates always stimulate economic growth by boosting the credit supply, investment, and consumption-and does not fully take into account several unintended channels of monetary policy, such as risk-taking, high level of debt, or zombification of the economy. In other words, the effectiveness of monetary policy is limited during economic downturns accompanied by the debt overhang and the balance sheet recession, and generates negative effects, which can make the policy counterproductive. The author provides a thorough analysis of the issues related to the interest rates in the conduct of monetary policy, such as the risk-taking channel of monetary policy, the portfolio-balance channel and the wealth effect, zombie firms in the economy, the misallocation of resources, as well as the neutral interest rate targeting and the difference between the neutral and natural interest rate and the negative interest rate policy. The book is written in an accessible and engaging manner and will be a valuable resource for scholars of monetary economics as well as readers interested in (unconventional) monetary policy.

European economies have been plagued by successive crises, from the Global Financial Crisis (GFC) to the COVID-19 pandemic, through to the economic and geopolitical instability in Ukraine. These events, the uncertainty they generate combined with dynamic technological progress and significant sociocultural changes, have profoundly modified the character of modern finance. Understanding what happened, what mechanisms worked, and the reaction of the banking sector, bank customers, and policymakers require an in-depth and structured analysis. This book critically assesses the impact of these events, notably the COVID-19 pandemic, on the performance of the banking sector in Europe and serves as a compendium of knowledge on recent changes in European banking from two perspectives: firstly, European banking transformation, analyzing the process of what has already taken place, in particular, the GFC and COVID-19 crises; secondly, the challenges facing the operations and strategic management of European banks. It identifies specific areas of impact on the activity of commercial banks and the determining factors that will shape the economic and financial condition of banks and their customers – borrowers – in the future. Risk management, particularly credit risk, is a key focus of this volume. Each chapter, implicitly or explicitly, address a variety of questions that can help the reader to understand the complex nature of the transformation of the banking sector. The book provides a structured reference for those concerned with the impact of volatility on the business models of modern banks. As such, it will find a broad audience among students, academics, banking, financial, business, and industry professionals, policymakers, and market regulators.

This book examines partnerships between commercial banks and microfinance institutions (MFIs). It demonstrates that when set up properly, these partnerships have the potential to develop and enhance the financial inclusion agenda, and further support sustainable development. MFIs provide access to finance predominantly for those who are poor but economically active, and therefore their expansion is imperative for inclusive economic development. However, MFIs are faced with enormous challenges. The book discusses how partnering with a commercial bank can meet these challenges and the process of interaction contributing to the enhancement of institutional robustness of MFIs. Through two distinct case studies, in Cambodia and Australia, the book discusses the motivations, objectives and operational dynamics of a partnership, as well as the challenges, success factors, and potential benefits, from the increase in outreach and sustainability, to the transference of knowledge and potential for capacity building. Similarly, the partnering banks benefit in line with the intended objectives-commercial or social besides help embedding social consciousness and improving staff engagement. Concluding with elucidating the characteristics of a partnership model that can succeed across different global contexts, the book will interest a range of researchers and students across development economics, banking, finance, and sustainable development.
