Available in PDF, EPUB and Kindle. Book excerpt: We evaluate the impact of portfolio constraints on financial markets in a dynamic equilibrium pure exchange economy with one consumption good and heterogeneous investors. Despite numerous applications, portfolio constraints are notoriously difficult to incorporate into dynamic equilibrium analysis unless constrained investors are assumed to have logarithmic preferences. Our solution method yields new insights on the impact of constraints on stock prices without relying on this assumption. We compute the equilibrium when both investors have (identical for simplicity) CRRA preferences, one of them is unconstrained while the other faces an upper bound constraint on the proportion of wealth invested in stocks. We show that tighter constraints lead to higher price-dividend ratios and lower stock-return volatilities when the intertemporal elasticity of substitution (IES) is less than one, and lower price-dividend ratios and higher volatilities when IES is greater than one. Moreover, in the latter case the model generates countercyclical market prices of risk and stock return volatilities, procyclical price-dividend ratios, excess volatility and other patterns consistent with empirical findings. Finally, the baseline analysis is extended to study the impact of various portfolio constraints when investors disagree on mean dividend growth rates. In particular, we explicitly characterize the equilibrium in the unconstrained benchmark economy as well as in the economy with unconstrained pessimist and optimist facing no-borrowing constraint.

Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the interaction of borrowing and short-sale constraints and their ultimate effects on asset pricing properties in a simultaneous presence of the constraints in a dynamic general equilibrium model with heterogeneous risk aversions and heterogeneous beliefs in the aggregate cash flow growth. The constraints negate the binding of each other, and hence they virtually never bind at once. Instead, there exist clear regions with alternative binding modes of the constraints with different constraints more likely to bind in different states of economy. The borrowing constraint is more active in bad times and the short-sale constraint is so in good times. The constraints bind intermittently--alternately at times--in transitory states of economy where their relative strength is balanced. Qualitatively matching empirically documented patterns of asset prices, I find that the constraints moderate their price effects but amplify their negative volatility effects, thereby can help curb the market volatility. However, a motive for speculation, featured by a speculative premium, arises due to any constraints, and thus can exist in any states of economy, not only in good times.

This book was released on 2013-03-09 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to give a sound economic foundation of finance. Finance is a coherent branch of applied economics that is designed to understand financial markets in order to give advice for practical financial decisions. This book argues that for a sound economic foundation of finance the famous general equilibrium model which in its modern form emphasizes the incompleteness of financial markets is well suited. The aim of the book is to demonstrate that financial markets can be meaningfully embedded into a more general system of markets including, for example, commodity markets. The interaction of these markets can be described via the well known notion of a competitive equilibrium. We argue that for a sound foundation this competitive equilibrium should be unique. In a first step we demonstrate that this essential goal cannot of be achieved based only on the rationality principle, i. e. on the assumption utility maximization of some utility function subject to the budget constraint. In particular we show that this important lack of structure is disturbing as well for the case of mean-variance utility functions which are the basis of the Capital Asset Pricing Model, one of the cornerstones of finance. The final goal of our book is to give reasonable restrictions on the agents' utility functions which lead to a well determined financial markets model.

Download or read book Asset Pricing with Heterogeneous Investors and Portfolio Constraints written by Georgy Chabakauri and published by . This book was released on 2014 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study general equilibrium in a Lucas (1978) economy with one consumption good and two investors with heterogeneous risk aversions and beliefs about aggregate consumption growth rate, and portfolio constraints. We provide a comprehensive comparison of various constraints, and show which of them and under what conditions help match the properties of asset prices in the data. We find that borrowing and short-sale constraints decrease stock return volatilities, whereas limited stock market participation constraints can increase volatilities even when investors have identical preferences and beliefs. Moreover, borrowing constraints generate spikes in interest rates and stock return volatilities when the constraint starts to bind. Finally, we find that short-sale constraints have smaller impact on asset prices than borrowing constraints, consistent with the empirical evidence on short-sale bans in the aftermath of 2007-09 financial crisis.

This book was released on 1993 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a simple general equilibrium model of asset pricing in which profitable informed trading can occur without any "noise" added to the model. It shows that models of profitable informed trading must restrict the portfolio choices of uninformed traders: in particular, they cannot buy the market portfolio. In this model, profitable informed trading lowers the welfare of all agents when compared across steady states.
Download or read book Asset Pricing with Dynamic Margin Constraints written by Oleg Rytchkov and published by . This book was released on 2014 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper provides a novel theoretical analysis of how endogenous time-varying margin requirements affect capital market equilibrium. It finds that margin requirements, when there are no other market frictions, reduce the volatility and the correlation of returns as well as the risk-free rate, but increase the market price of risk, the risk premium, and the price of risky assets. Furthermore, margin requirements generate a strong cross-sectional dispersion of stock return volatilities. The paper emphasizes that a general equilibrium analysis may reverse the conclusions of a partial equilibrium analysis often employed in the literature.
Download or read book Overreaction of Asset Prices in General Equilibrium written by S. Rao Aiyagari and published by . This book was released on 2000 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: We attempt to explain the overreaction of asset prices to movements in short-term interest rates, dividends, and asset supplies. The key element of our explanation is a margin constraint that traders face which limits their leverage to a fraction of the value of their assets. Traders may lever themselves further, either directly by borrowing short term or indirectly by engaging in futures and options trading, so that the scenario is relevant to contemporary financial markets. When some shock pushes asset prices to a low enough level at which the margin constraint binds, traders are forced to liquidate assets. This drives asset prices below what they would be with frictionless markets. Also, a shock which simply increases the likelihood that the margin constraint will bind can have a very similar effect on asset prices. We construct a general equilibrium model with margin constrained traders and derive some qualitative properties of asset prices. We present an analytical solution for a deterministic version of the model and a simple numerical computation of the stochastic version.

Download or read book Advanced Asset Pricing Theory written by Ma Chenghu and published by World Scientific Publishing Company. This book was released on 2011-01-03 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a broad introduction of modern asset pricing theory with equal treatments for both discrete-time and continuous-time modeling. Both the no-arbitrage and the general equilibrium approaches of asset pricing theory are treated coherently within the general equilibrium framework.The analyses and coverage are up to date, comprehensive and in-depth. Topics include microeconomic foundation of asset pricing theory, the no-arbitrage principle and fundamental theorem, risk measurement and risk management, sequential portfolio choice, equity premium decomposition, option pricing, bond pricing and term structure of interest rates. The merits and limitations are expounded with respect to allocation and information market efficiency, along with the classical expectations hypothesis concerning the information content of yield curve and bond prices. Efforts are also made towards the resolution of several well-documented puzzles in empirical finance, which include the equity premium puzzle, the risk free rate puzzle, and the money-ness bias phenomenon of Black-Scholes option pricing model.The theory is self-contained and unified in presentation. The inclusion of proofs and derivations to enhance the transparency of the underlying arguments and conditions for the validity of the economic theory makes an ideal advanced textbook or reference book for graduate students specializing in financial economics and quantitative finance. The explanations are detailed enough to capture the interest of those curious readers, and complete enough to provide necessary background material needed to explore further the subject and research literature.
