Download or read book Volatility Surface and Term Structure written by Kin Keung Lai and published by Routledge. This book was released on 2013-09-11 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides different financial models based on options to predict underlying asset price and design the risk hedging strategies. Authors of the book have made theoretical innovation to these models to enable the models to be applicable to real market. The book also introduces risk management and hedging strategies based on different criterions. These strategies provide practical guide for real option trading. This book studies the classical stochastic volatility and deterministic volatility models. For the former, the classical Heston model is integrated with volatility term structure. The correlation of Heston model is considered to be variable. For the latter, the local volatility model is improved from experience of financial practice. The improved local volatility surface is then used for price forecasting. VaR and CVaR are employed as standard criterions for risk management. The options trading strategies are also designed combining different types of options and they have been proven to be profitable in real market. This book is a combination of theory and practice. Users will find the applications of these financial models in real market to be effective and efficient.
Download or read book The Long run Volatility Puzzle of the Real Exchange Rate written by Ricardo Hausmann and published by . This book was released on 2004 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This paper documents large cross-country differences in the long run volatility of the real exchange rate. In particular, it shows that the real exchange rate of developing countries is approximately three times more volatile than the real exchange rate in industrial countries. The paper tests whether this difference in volatility can be explained by the fact that developing countries face larger shocks (both real and nominal) and recurrent currency crises or by different elasticities to these shocks. It finds that the magnitude of the shocks and the differences in elasticities can only explain a small part of the difference in RER volatility between developing and industrial countries. Results from ARCH estimations confirm that there is a substantial difference in long term volatilities between these two sets of countries and indicate that there is also a much higher persistence of deviations of the variance of the RER from its long run value when the economy suffers shocks of various kinds"--NBER website

Book excerpt: This paper provides a simple theoretical framework for assessing the empirical linkages between returns and realized and implied volatilities. First, we show that whereas the volatility feedback effect as measured by the sign of the correlation between contemporaneous return and realized volatility depends importantly on the underlying structural model parameters, the correlation between return and implied volatility is unambiguously positive for all reasonable parameter configurations. Second, the asymmetric response of current volatility to lagged negative and positive returns, typically referred to as the leverage effect, is always stronger for implied than realized volatility. Third, implied volatilities generally provide downward biased forecasts of subsequent realized volatilities. Our results help explain previous findings reported in the extant empirical literature, and is further corroborated by new estimation results for a sample of monthly returns and implied and realized volatilities for the S amp;P500 aggregate market index.

Available in PDF, EPUB and Kindle. Book excerpt: "We also address a variety of international pricing puzzles, including the purchasing power parity puzzle emphasized by Rogoff, and what we term "the exchange rate disconnect puzzle." The latter category of riddles includes both the Meese-Rogoff exchange rate forecasting puzzle and the Baxter-Stockman neutrality of exchange rate regime puzzle. Here, although many elements need to be added to our extremely simple model, trade costs still play an essential role."--Authors.

This book was released on 1999-03-01 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper develops a flow model of the exchange rate with speculative capital flows integrated in a rigorous manner. The model is consistent with five foreign exchange market puzzles: (1) occasional discontinuous jumps in the exchange rate; (2) periodic short-term regimes of persistent appreciation/depreciation that can develop into a long swing; (3) the forward discount bias; (4) volatility clusters in the foreign exchange market that create conditional heteroskedasticity; and (5) the dual profitability of betting in the short run against any official foreign exchange intervention, and betting with the intervention in the long run.
Download or read book The Fear Economy A Theory of Output Interest and Safe Assets written by Ruchir Agarwal and published by International Monetary Fund. This book was released on 2022-09-09 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a fear theory of the economy, based on the interplay between fear of rare disasters and the interest rate on safe assets. To do this, I study the macroeconomic consequences of government-administered interest rates in the neoclassical real business cycle model. When the government has the power to fix the safe real interest rate, the gap between the `sticky real safe rate' and the `neutral rate' can generate far-reaching aggregate distortions. When fear exogenously rises, the demand for safe assets rise and the neutral rate falls. If the central bank does not lower the safe rate by the same amount, savings rise leading to a decline in consumption and aggregate demand. The same mechanism works in reverse, when fear falls. Quantitatively, I show that a single fear factor can simultaneously (i) generate cross-correlations in output, labor, consumption, and investment consistent with the postwar US economy; and (ii) generates variation in equity prices, bond prices, and a large risk premium in line with the asset pricing data. Six novel insights emerge from the model: (1) actively regulating the safe interest rate (in both directions) can mitigate the fluctuations generated by fear cycles; (2) recessions will be deeper and longer when central banks accept the zero lower bound and are unwilling to use negative rates; (3) a commitment to use negative rates in recessions—even if never implemented—raises both the short- and long-run real neutral rates, and moderates the business cycle; (4) counter-cyclical fiscal policy can act as disaster insurance and be expansionary by reducing fear; (5) quantitative easing can be narrowly effective only when fear is high at the lower bound; and (6) when fear is high, especially at the lower bound, policies that boost productivity also help fight recessions.

Available in PDF, EPUB and Kindle. Book excerpt: In the 2nd edition of Asset Pricing and Portfolio Choice Theory, Kerry E. Back offers a concise yet comprehensive introduction to and overview of asset pricing. Intended as a textbook for asset pricing theory courses at the Ph.D. or Masters in Quantitative Finance level with extensive exercises and a solutions manual available for professors, the book is also an essential reference for financial researchers and professionals, as it includes detailed proofs and calculations as section appendices. The first two parts of the book explain portfolio choice and asset pricing theory in single-period, discrete-time, and continuous-time models. For valuation, the focus throughout is on stochastic discount factors and their properties. A section on derivative securities covers the usual derivatives (options, forwards and futures, and term structure models) and also applications of perpetual options to corporate debt, real options, and optimal irreversible investment. A chapter on "explaining puzzles" and the last part of the book provide introductions to a number of additional current topics in asset pricing research, including rare disasters, long-run risks, external and internal habits, asymmetric and incomplete information, heterogeneous beliefs, and non-expected-utility preferences. Each chapter includes a "Notes and References" section providing additional pathways to the literature. Each chapter also includes extensive exercises.

Download or read book Uncertainty and Economics written by Christian Müller-Kademann and published by Routledge. This book was released on 2019-01-08 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is set against the assumption that humans' unique feature is their infinite creativity, their ability to reflect on their deeds and to control their actions. These skills give rise to genuine uncertainty in society and hence in the economy. Here, the author sets out that uncertainty must take centre stage in all analyses of human decision making and therefore in economics. Uncertainty and Economics carefully defines a taxonomy of uncertainty and argues that it is only uncertainty in its most radical form which matters to economics. It shows that uncertainty is a powerful concept that not only helps to resolve long-standing economic puzzles but also unveils serious contradictions within current, popular economic approaches. It argues that neoclassical, real business cycle, or new-Keynesian economics must be understood as only one way to circumvent the analytical challenges posed by uncertainty. Instead, embracing uncertainty offers a new analytical paradigm which, in this book, is applied to standard economic topics such as institutions, money, the Lucas critique, fiscal policy and asset pricing. Through applying a concise uncertainty paradigm, the book sheds new light on human decision making at large. Offering policy conclusions and recommendations for further theoretical and applied research, it will be of great interest to postgraduate students, academics and policy makers.

Download or read book Demystifying the Meese Rogoff Puzzle written by I. Moosa and published by Springer. This book was released on 2014-12-17 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past 30 years international monetary economists have believed that exchange rate models cannot outperform the random walk in out-of-sample forecasting as a result of the 1983 paper written by Richard Meese and Kenneth Rogoff. Marking the culmination of their extensive research into the Meese-Rogoff puzzle, Moosa and Burns challenge the orthodoxy by demonstrating that the naïve random walk model can be outperformed by exchange rate models when forecasting accuracy is measured by metrics that do not rely exclusively on the magnitude of forecasting error. The authors present compelling evidence, supported by their own measure: the 'adjusted root mean square error', to finally solve the Meese-Rogoff puzzle and provide a new alternative. Demystifying the Meese-Rogoff Puzzle will appeal to academics with an interest in exchange rate economics and international monetary economics. It will also be a useful resource for central banks and financial institutions.
Download or read book The Puzzle of Brazil s High Interest Rates written by Mr.Alex Segura-Ubiergo and published by International Monetary Fund. This book was released on 2012-02-01 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper highlights that real interest rates in Brazil have declined substantially over time, but are still well above the average of emerging market inflation targeting regimes. The adoption of an inflation-targeting regime and better economic fundamentals (reduction in inflation volatility and improvements in the fiscal and external positions) has helped Brazil sustain significantly lower real interest rates than in the past. Going forward, the paper shows that Brazil can converge towards lower equilibrium real interest rates if domestic savings increase to the level of other emerging market countries. The effect is particularly pronounced if the increase in domestic savings is achieved through higher levels of public savings. Still, econometric results suggest that, controlling for everything else in the model, real interest rates in Brazil are about two full percentage points higher than in other countries in the sample, suggesting that there are still Brazil-specific factors that have not been captured by the empirical analysis. Some of these factors may include credit market segmentation and inflation inertia generated by still pervasive indexation practices.
Download or read book Zombie Economics written by John Quiggin and published by Princeton University Press. This book was released on 2012-05-21 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the graveyard of economic ideology, dead ideas still stalk the land. The recent financial crisis laid bare many of the assumptions behind market liberalism--the theory that market-based solutions are always best, regardless of the problem. For decades, their advocates dominated mainstream economics, and their influence created a system where an unthinking faith in markets led many to view speculative investments as fundamentally safe. The crisis seemed to have killed off these ideas, but they still live on in the minds of many--members of the public, commentators, politicians, economists, and even those charged with cleaning up the mess. In Zombie Economics, John Quiggin explains how these dead ideas still walk among us--and why we must find a way to kill them once and for all if we are to avoid an even bigger financial crisis in the future. Zombie Economics takes the reader through the origins, consequences, and implosion of a system of ideas whose time has come and gone. These beliefs--that deregulation had conquered the financial cycle, that markets were always the best judge of value, that policies designed to benefit the rich made everyone better off--brought us to the brink of disaster once before, and their persistent hold on many threatens to do so again. Because these ideas will never die unless there is an alternative, Zombie Economics also looks ahead at what could replace market liberalism, arguing that a simple return to traditional Keynesian economics and the politics of the welfare state will not be enough--either to kill dead ideas, or prevent future crises. In a new chapter, Quiggin brings the book up to date with a discussion of the re-emergence of pre-Keynesian ideas about austerity and balanced budgets as a response to recession.
