Working Paper Department of Economics a Liquidity Based Asset Pricing Model
نویسنده
چکیده
The intertemporal CAPM predicts that an asset's price is equal to the expectation of the product of the asset's payoff and a representative consumer's intertemporal marginal rate of substitution. This paper develops an alternative approach to asset pricing based on industrial and financial corporations' desire to hoard liquidity to fulfill future cash needs. Our corporate finance approach to market finance suggests new determinants of asset prices such as the distribution of wealth within the corporate sector and between the corporate sector and the consumers. Also, leverage ratios, capital adequacy requirements, and the composition of savings affect the corporate demand for liquid assets and thereby interest rates. The paper first sets up a general model of corporate demand for liquid assets, and obtains an explicit formula for the associated liquidity premia. It then derives some implications of corporate liquidity demand for the equity premium puzzle, for the yield curve, and for the state-contingent volatility of asset prices. Finally, the paper looks at some macroeconomic implications of the theory. It shows that government may be able to boost aggregate liquidity and enhance economic efficiency by promoting job and asset price stability. On the liability side, long-term deposits and equity investments, which depend on the consumers' endogenously determined liquidity needs, contribute to creating a feedback effect between employment prospects and equity-like investments. On the asset side, orderly sales of real estate by liquidity-squeezed institutions may generate a Pareto improvement.

Consumption-Based Asset Pricing with Recursive Utility
In this paper it has been attempted to investigate the capability of the consumption-based capital asset pricing model (CCAPM), using the general method of moment (GMM), with regard to the Epstien-zin recursive preferences model for Iran's capital market. Generally speaking, recursive utility permits disentangling of the two psychologically separate concepts of risk aversion and elasticity of i...

This paper proposes a new non-parametric method for estimating model-free, time-varying liquidity betas which builds on realized covariance and volatility theory. Working under a liquidityadjusted CAPM framework we provide evidence that liquidity risk is a factor priced in the Greek stock market, mainly arising from the covariation of individual liquidity with local market liquidity, however, t...

The aim of this study is to examine the equity premium puzzle in Iran for the quarterly period of 1993-2016. In this regard, the hybrid bivariate Garch model and also fuzzy dummy variables with consumption capital asset pricing model (C-CAPM) have been used.
