This book was released on 2018 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subsistence consumption and investment problems with bankruptcy are classic constrained stochastic optimal control problem in financial economic, where the consumption rate should be greater than a positive number and the investor faces a bankruptcy payment. We derive novel asymptotic solution to this problem under the fast mean-reverting stochastic volatility model. We rigorously prove that the zeroth-order approximation for the optimal pair of consumption and investment strategies leads to the first-order accuracy of the objective function. In addition, this zeroth-order suboptimal consumption-investment pair is asymptotically optimal in a class of admissible trading strategy pairs.

Book Synopsis Dynamic Consumption and Portfolio Choice with Stochastic Volatility in Incomplete Markets by : Luis M. Viceira
Download or read book Dynamic Consumption and Portfolio Choice with Stochastic Volatility in Incomplete Markets written by Luis M. Viceira and published by . This book was released on 1999 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This paper analyzes optimal portfolio choice and consumption with stochastic volatility in incomplete markets. Using the Duffie-Epstein (1992) formulation of recursive utility in continuous time, it shows that the optimal portfolio demand for stocks under stochastic volatility varies strongly with the investor's coefficient of relative risk aversion, but only slightly with her elasticity of intertemporal substitution; by contrast, optimal consumption relative to wealth depends on both preference parameters. This paper also shows that stochastic variation in volatility produces an optimal intertemporal hedging demand for stocks which is negative when changes in volatility are instantaneously negatively correlated with excess stock returns and investors have coefficients of relative risk aversion larger than one. The absolute size of this demand increases with the size of this correlation, and also with the persistence of shocks to volatility. An application to the US stock market shows that empirically this correlation is negative and large, which implies a negative hedging demand for stocks. This application also shows that only low frequency shocks to volatility exhibit enough persistence to generate sizable hedging demands by long-term, risk averse investors. A comparative statics exercise shows that the size of hedging demands is considerably more sensitive to changes in persistence than to changes in correlation.

Book Synopsis Strategic Asset Allocation by : John Y. Campbell
Download or read book Strategic Asset Allocation written by John Y. Campbell and published by OUP Oxford. This book was released on 2002-01-03 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic finance has had a remarkable impact on many financial services. Yet long-term investors have received curiously little guidance from academic financial economists. Mean-variance analysis, developed almost fifty years ago, has provided a basic paradigm for portfolio choice. This approach usefully emphasizes the ability of diversification to reduce risk, but it ignores several critically important factors. Most notably, the analysis is static; it assumes that investors care only about risks to wealth one period ahead. However, many investors—-both individuals and institutions such as charitable foundations or universities—-seek to finance a stream of consumption over a long lifetime. In addition, mean-variance analysis treats financial wealth in isolation from income. Long-term investors typically receive a stream of income and use it, along with financial wealth, to support their consumption. At the theoretical level, it is well understood that the solution to a long-term portfolio choice problem can be very different from the solution to a short-term problem. Long-term investors care about intertemporal shocks to investment opportunities and labor income as well as shocks to wealth itself, and they may use financial assets to hedge their intertemporal risks. This should be important in practice because there is a great deal of empirical evidence that investment opportunities—-both interest rates and risk premia on bonds and stocks—-vary through time. Yet this insight has had little influence on investment practice because it is hard to solve for optimal portfolios in intertemporal models. This book seeks to develop the intertemporal approach into an empirical paradigm that can compete with the standard mean-variance analysis. The book shows that long-term inflation-indexed bonds are the riskless asset for long-term investors, it explains the conditions under which stocks are safer assets for long-term than for short-term investors, and it shows how labor income influences portfolio choice. These results shed new light on the rules of thumb used by financial planners. The book explains recent advances in both analytical and numerical methods, and shows how they can be used to understand the portfolio choice problems of long-term investors.
Book Synopsis Capital as Power by : Jonathan Nitzan
Download or read book Capital as Power written by Jonathan Nitzan and published by Routledge. This book was released on 2009-06-02 with total page 853 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional theories of capitalism are mired in a deep crisis: after centuries of debate, they are still unable to tell us what capital is. Liberals and Marxists both think of capital as an ‘economic’ entity that they count in universal units of ‘utils’ or ‘abstract labour’, respectively. But these units are totally fictitious. Nobody has ever been able to observe or measure them, and for a good reason: they don’t exist. Since liberalism and Marxism depend on these non-existing units, their theories hang in suspension. They cannot explain the process that matters most – the accumulation of capital. This book offers a radical alternative. According to the authors, capital is not a narrow economic entity, but a symbolic quantification of power. It has little to do with utility or abstract labour, and it extends far beyond machines and production lines. Capital, the authors claim, represents the organized power of dominant capital groups to reshape – or creorder – their society. Written in simple language, accessible to lay readers and experts alike, the book develops a novel political economy. It takes the reader through the history, assumptions and limitations of mainstream economics and its associated theories of politics. It examines the evolution of Marxist thinking on accumulation and the state. And it articulates an innovative theory of ‘capital as power’ and a new history of the ‘capitalist mode of power’.

Book Synopsis Controlled Diffusion Processes by : N. V. Krylov
Download or read book Controlled Diffusion Processes written by N. V. Krylov and published by Springer Science & Business Media. This book was released on 2008-09-26 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stochastic control theory is a relatively young branch of mathematics. The beginning of its intensive development falls in the late 1950s and early 1960s. ~urin~ that period an extensive literature appeared on optimal stochastic control using the quadratic performance criterion (see references in Wonham [76]). At the same time, Girsanov [25] and Howard [26] made the first steps in constructing a general theory, based on Bellman's technique of dynamic programming, developed by him somewhat earlier [4]. Two types of engineering problems engendered two different parts of stochastic control theory. Problems of the first type are associated with multistep decision making in discrete time, and are treated in the theory of discrete stochastic dynamic programming. For more on this theory, we note in addition to the work of Howard and Bellman, mentioned above, the books by Derman [8], Mine and Osaki [55], and Dynkin and Yushkevich [12]. Another class of engineering problems which encouraged the development of the theory of stochastic control involves time continuous control of a dynamic system in the presence of random noise. The case where the system is described by a differential equation and the noise is modeled as a time continuous random process is the core of the optimal control theory of diffusion processes. This book deals with this latter theory.
Book Synopsis Handbook of Portfolio Construction by : John B. Guerard, Jr.
Download or read book Handbook of Portfolio Construction written by John B. Guerard, Jr. and published by Springer Science & Business Media. This book was released on 2009-12-12 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portfolio construction is fundamental to the investment management process. In the 1950s, Harry Markowitz demonstrated the benefits of efficient diversification by formulating a mathematical program for generating the "efficient frontier" to summarize optimal trade-offs between expected return and risk. The Markowitz framework continues to be used as a basis for both practical portfolio construction and emerging research in financial economics. Such concepts as the Capital Asset Pricing Model (CAPM) and the Arbitrage Pricing Theory (APT), for example, provide the foundation for setting benchmarks, for predicting returns and risk, and for performance measurement. This volume showcases original essays by some of today’s most prominent academics and practitioners in the field on the contemporary application of Markowitz techniques. Covering a wide spectrum of topics, including portfolio selection, data mining tests, and multi-factor risk models, the book presents a comprehensive approach to portfolio construction tools, models, frameworks, and analyses, with both practical and theoretical implications.
Book Synopsis Optimal Consumption and Investment with Bankruptcy by : Suresh P. Sethi
Download or read book Optimal Consumption and Investment with Bankruptcy written by Suresh P. Sethi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents papers on continuous-time consumption investment models by Suresh Sethi and various co-authors. Sir Isaac Newton said that he saw so far because he stood on the shoulders of gi ants. Giants upon whose shoulders Professor Sethi and colleagues stand are Robert Merton, particularly Merton's (1969, 1971, 1973) seminal papers, and Paul Samuelson, particularly Samuelson (1969). Karatzas, Lehoczky, Sethi and Shreve (1986), henceforth KLSS, re produced here as Chapter 2, reexamine the model proposed by Mer ton. KLSS use methods of modern mathematical analysis, taking care to prove the existence of integrals, check the existence and (where appro priate) the uniqueness of solutions to equations, etc. KLSS find that un der some conditions Merton's solution is correct; under others, it is not. In particular, Merton's solution for aHARA utility-of-consumption is correct for some parameter values and not for others. The problem with Merton's solution is that it sometimes violates the constraints against negative wealth and negative consumption stated in Merton (1969) and presumably applicable in Merton (1971 and 1973). This not only affects the solution at the zero-wealth, zero-consumption boundaries, but else where as well. Problems with Merton's solution are analyzed in Sethi and Taksar (1992), reproduced here as Chapter 3.

Book Synopsis Contemporary Issues in Business and Economics by : Chia-Lin Chang
Download or read book Contemporary Issues in Business and Economics written by Chia-Lin Chang and published by MDPI. This book was released on 2020-07-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of high-impact papers accepted and presented at the 2019 Vietnam’s Business and Economics Research Conference (VBER2019) organised by Ho Chi Minh City Open University held on 18th–20th July 2019. The Special Issue is associated with a broad coverage of the contemporary issues in Business and Economics in Vietnam and other emerging markets reflecting a key theme of VBER2019: Vietnam’s Place in the Asia Pacific Region. A total of 14 papers were published from more than the 120 submissions to the VBER2019 Conference. Published papers had been undergone a rigorous reviewing process conducted by the Journal of Risk and Financial Management. The papers incorporated in this book address contemporary issues in business and economics from Vietnam and other emerging markets in the Asian region from various angles such as economics, finance, and statistics to management science. At the time of writing this note, some of the papers have attracted more than 1000 downloads in 3 months. In particular, a paper on “Foreign Direct Investment and Economic Growth from Developing Countries in the Short Run and Long Run” by Trang Thi-Huyen Dinh and her team has attracted almost 6000 downloads in 3 months. These statistics indicate that the papers published in this Special Issue have attracted the wide interest of readers. Among these 14 published papers, three main areas of important contemporary issues in Business and Economics in the Asian region can be identified. First, a block of papers deals with various important and fundamental issues in the emerging markets the Asian region, from exchange rate regime, financial inclusion, and financial development to energy consumption and environmental degradation. On the issue of CO2 emissions, energy consumption and economic growth in the ASEAN, Vo, Vo, and Le utilized various time series econometrics approaches. Key findings from this paper indicate that there are no long-run relationships among carbon dioxide (CO2) emissions, energy consumption, renewable energy, population growth, and economic growth in the Philippines and Thailand, but a relationship does exist in Indonesia, Myanmar, and Malaysia. Loo, in his paper on financial inclusion for the ASEAN, concluded that advancing internet capability and availability present investors an opportunity to offer financial technology or Fintech to meet the need for financial services in this digital era. Second, a challenge in quantitative studies for a single country, such as Vietnam, with limited data is generally noted. However, various empirical studies on Vietnam’s business and economics issues have been conducted. Nguyen, Quan, and Pham examined the cultural distance and entry mode of foreign direct investment in Vietnam. A key finding from their paper is that when there is a great cultural difference between Vietnam and their home country, foreign-invested firms prefer wholly owned subsidiaries over equity joint ventures. Within the Vietnamese market, Pham, Vo, Ho, and McAleer conducted a study on the issue of corporate financial distress. The authors conclude that the corporate financial distress prediction model, which includes accounting factors with macroeconomic indicators, performs much better than alternative models. In addition, the evidence confirms that the global financial crisis (GFC) had a damaging impact on each sector, with the Health & Education sector demonstrating the most impressive recovery post-GFC, and the utilities sector recording a dramatic increase in bankruptcies post-GFC. At another extreme of the spectrum, Van and Nguyen considered that competitive context, social influences, the understanding of managers about corporate social responsibility (CSR), and the internal environment of companies are the four drivers of CSR. The authors also argued that in the four drivers, competitive context has the strongest impact on adopting CSR. Third, last but not least, various papers focus on an important aspect of public finance. For an example, Pham, Pham, and Ly documented the effect of double taxation treaties on the bilateral trade of Vietnam with ASEAN member states, thereby making an extensive comparison with its EU partner countries. Their findings indicate the significant contributions of the tax treaties to Vietnam’s trade performance, not exclusively with ASEAN but also with EU partner countries. In addition, regarding public finance for Vietnam, Nguyen, Vo, Ho, and Vo investigated the contribution of fiscal decentralisation to economic growth across provinces in Vietnam. For the first time in Vietnam, the fiscal decentralisation index together its two subcomponents, including fiscal importance and fiscal autonomy, are developed. Findings from this paper indicate that while fiscal importance and an overall level of fiscal decentralisation have provided negative impact on provincial economic growth, fiscal autonomy has a positive impact on economic growth across provinces in Vietnam.
Book Synopsis The Kelly Capital Growth Investment Criterion by : Leonard C. MacLean
Download or read book The Kelly Capital Growth Investment Criterion written by Leonard C. MacLean and published by World Scientific. This book was released on 2011 with total page 883 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides the definitive treatment of fortune's formula or the Kelly capital growth criterion as it is often called. The strategy is to maximize long run wealth of the investor by maximizing the period by period expected utility of wealth with a logarithmic utility function. Mathematical theorems show that only the log utility function maximizes asymptotic long run wealth and minimizes the expected time to arbitrary large goals. In general, the strategy is risky in the short term but as the number of bets increase, the Kelly bettor's wealth tends to be much larger than those with essentially different strategies. So most of the time, the Kelly bettor will have much more wealth than these other bettors but the Kelly strategy can lead to considerable losses a small percent of the time. There are ways to reduce this risk at the cost of lower expected final wealth using fractional Kelly strategies that blend the Kelly suggested wager with cash. The various classic reprinted papers and the new ones written specifically for this volume cover various aspects of the theory and practice of dynamic investing. Good and bad properties are discussed, as are fixed-mix and volatility induced growth strategies. The relationships with utility theory and the use of these ideas by great investors are featured.
Book Synopsis Bangladesh's Economic and Social Progress by : Munim Kumar Barai
Download or read book Bangladesh's Economic and Social Progress written by Munim Kumar Barai and published by Springer Nature. This book was released on 2020-03-31 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book evaluates Bangladesh’s impressive economic and social progress, more often referred to as a ‘development surprise’. In doing so, the book examines the gap in existing explanations of Bangladesh’s development and then offers an empirically informed analysis of a range of distinctive factors, policies, and actions that have individually and collectively contributed to the progress of Bangladesh. In an inclusive way, the book covers the developmental role, relation, and impact of poverty reduction, access to finance, progress in education and social empowerment, reduction in the climatic vulnerability, and evolving sectoral growth activities in the agriculture, garments, and light industries. It also takes into account the important role of the government and NGOs in the development process, identifies bottlenecks and challenges to Bangladesh’s future development path and suggests measures to overcome them. By providing an inclusive narrative to theorize Bangladesh’s development, which is still missing in the public discourse, this book posits that Bangladesh per se can offer a development model to other developing countries.
Book Synopsis The Economics of Keynes by : Mark G. Hayes
Download or read book The Economics of Keynes written by Mark G. Hayes and published by Edward Elgar Publishing. This book was released on 2006 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his 'New Guide' to The General Theory, Mark G. Hayes presents Keynes's illustrious work as a sophisticated Marshallian theory of the competitive equilibrium of the economy as a whole. This unique book takes full account of the nature of time and money and illustrates that The General Theory remains highly relevant to the teacher and advanced student of modern macroeconomics. The Economics of Keynes introduces several interpretative innovations to resolve many puzzles presented in the literature of the last 70 years. It is designed to be read in parallel with The General Theory and will allow modern readers to find their bearings before plunging into an in-depth analysis of major themes contained in The General Theory. The key areas in which this 'New Guide' differs from the familiar exposition of current macroeconomics textbooks are also explicitly identified. The author reaches positive and hopeful conclusions for the development of economic theory and policy. Promoting a thorough understanding of the legitimate domain of equilibrium analysis and a renewed commitment to the possibility of genuinely full employment, this book will provide an illuminating and fascinating read for anyone wishing to appreciate fully the value of The General Theory. More specifically, academics and advanced students of macroeconomics across the board - classical, orthodox, Post Keynesian and heterodox - interested in a fresh attempt to connect The General Theory with modern macroeconomics will find this book to be the ideal tool.
