A new jump diffusion regime-switching model is introduced, which allows for linking jumps in asset prices with regime changes. We prove the existence and uniqueness of the solution to the risk-sensitive asset management criterion maximisation problem in this setting. We provide an ODE for the optimal value function, which may be efficiently solved numerically. Relevant probability measure changes are discussed in the appendix. The approach of Klebaner & Lipster (2014) is used to prove the martingale property of the relevant density processes.
One of the most challenging issues for the current state of global economy is a highly uneven distribution of global financial assets and liabilities. Drawing on extensive data, this book analyses the new global divisions in economic and financial inequality across the globe in the first two decades of this century. After outlining the context of the global financial system in the aftermath of the Global Financial Crisis of 2008/2009, this book provides a detailed examination of the data on economic and financial inequality, analysing growth rates relative to financial liabilities and assets for all countries where data is available. The central issues in understanding the financial and environmental efficiency of economic growth are also addressed as well as the development of financial and regulatory technologies (FinTech and RegTech). The final part of this book explores the changes in economic growth and financial assets/liabilities as a result of major events in the past three years: Covid Crisis, the rise of inflation and the Russian invasion of Ukraine. The focal point of this analysis is the relationship between the speed of economic growth, the use of financial resources for funding that growth and levels of inequality. The green transition, as one of the most important challenges in the global economy, is an integral part of this analysis, along with the inequality in available financial resources for this transition and potential threats to global financial stability. This book will be vital reading for those interested in inequality, financial economics, the global financial system and economic growth.
Mit diesem Buch legt der Wissenschaftler Dr. Nicolaus A. Berlin den Grundstein für eine Wirtschaftstheorie, die auf Motivation und Instinkten fußt. Berlin präsentiert ein neues Konzept wirtschaftlichen Denkens und Handelns, das sich die nicht-rationalen Aspekte unseres Handelns zunutze macht: die Animal Spirits. Er beleuchtet die Auswirkung psychologischer Faktoren auf unser wirtschaftliches Handeln und zeigt, was uns und unsere Ökonomie tatsächlich antreibt, beeinflusst und immer wieder maßgeblich verändert.
From acclaimed economists George Akerlof and Robert Shiller, the case for why government is needed to restore confidence in the economy The global financial crisis has made it painfully clear that powerful psychological forces are imperiling the wealth of nations today. From blind faith in ever-rising housing prices to plummeting confidence in capital markets, "animal spirits" are driving financial events worldwide. In this book, acclaimed economists George Akerlof and Robert Shiller challenge the economic wisdom that got us into this mess, and put forward a bold new vision that will transform economics and restore prosperity. Akerlof and Shiller reassert the necessity of an active government role in economic policymaking by recovering the idea of animal spirits, a term John Maynard Keynes used to describe the gloom and despondence that led to the Great Depression and the changing psychology that accompanied recovery. Like Keynes, Akerlof and Shiller know that managing these animal spirits requires the steady hand of government—simply allowing markets to work won't do it. In rebuilding the case for a more robust, behaviorally informed Keynesianism, they detail the most pervasive effects of animal spirits in contemporary economic life—such as confidence, fear, bad faith, corruption, a concern for fairness, and the stories we tell ourselves about our economic fortunes—and show how Reaganomics, Thatcherism, and the rational expectations revolution failed to account for them. Animal Spirits offers a road map for reversing the financial misfortunes besetting us today. Read it and learn how leaders can channel animal spirits—the powerful forces of human psychology that are afoot in the world economy today. In a new preface, they describe why our economic troubles may linger for some time—unless we are prepared to take further, decisive action.
'Animal spirits' is a term that describes the instincts and emotions driving human behaviour in economic settings. In recent years, this concept has been discussed in relation to the emerging field of narrative economics. When unscheduled events hit the stock market, from corporate scandals and technological breakthroughs to recessions and pandemics, relationships driving returns change in unforeseeable ways. To deal with uncertainty, investors engage in narratives which simplify the complexity of real-time, non-routine change. This book assesses the novelty-narrative hypothesis for the U.S. stock market by conducting a comprehensive investigation of unscheduled events using big data textual analysis of financial news. This important contribution to the field of narrative economics finds that major macro events and associated narratives spill over into the churning stream of corporate novelty and sub-narratives, spawning different forms of unforeseeable stock market instability.
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px Arial} The last few decades have witnessed an outpouring of literature on macroeconomic models in the broad ‘heterodox’ tradition of Marx, Keynes, Robinson, Kaldor and Kalecki. These models yield an alternative analytical framework in which the big questions of our day – such as how inequality is related to growth or stagnation, and whether long-run growth is stable or unstable – can be fruitfully addressed. Heterodox Macroeconomics provides an accessible, pedagogically oriented treatment of the leading models and approaches in heterodox macroeconomics with clear, step-by-step presentations of core models and their solutions, properties and implications.
In this work, the authors offer a unified, transdisciplinary approach for achieving sustainable development in industrialized nations. They present an insightful analysis of the ways in which industrial states are unsustainable and how economic and social welfare are related to the environment, public health and safety.
The euro's life, while only slightly more than a decade long, has been riddled by a series of challenges and crises. The eruption of the Greek crisis in 2010 took European policymakers by surprise and forced them to design responses to a quickly deteriorating situation. Even though Europe has final begun to stabilize, the disparity between the prosperous Northern countries, especially Germany, and the plummeting Southern countries, including Spain and Greece, has exacerbated economic and political problems within the Eurozone. Amidst loud and frequent debates, solutions have been enacted, but the struggles facing this monetary union continue to develop even today. The Euro Crisis and Its Aftermath was written to inform readers about the roots of this enduring European crisis and the alternative proposals for ending it. In four parts, Jean Pisani-Ferry explains the origins of the European currency, the build-up of imbalances and oversights that led to the crisis, the choices European policymakers have both addressed and ignored since 2010, and the evolution of the policy agenda and possible options for the future. The book is as much of an informative and analytical history as it is a discussion of solutions for a more prosperous European economy. Rather than putting forth and supporting a thesis, Pisani-Ferry helps readers understand the past and present of the euro crisis and form their own opinions about potential solutions. This book is not intended to reach only economists, as time has long passed since European monetary unification was a debate limited to academics. This book is also for the policy makers searching for solutions, citizens of Europe enduring the consequences, and the international community that has felt the effects of an unstable Eurozone.
This volume presents studies to explain international investment behaviour and assess its impact on growth and jobs. The authors also examine policy measures to reverse the climate of low investment that has characterised recent years
