Recent literature (McNulty, Yeh, Schulze, & Lubatkin, 2002) states that the assumptions behind the capital asset pricing model, in particular the irrelevance of time horizon, do not correspond to the characteristics of firms that prefer long-term investment horizons. I show that family firms display a longer time horizon than most of their nonfamily counterparts, since (1) family firms display ...

We investigate the properties of mean-variance efficient portfolios when the number of assets is large. We show analytically and empirically that the proportion of assets held short converges to 50% as the number of assets grows, and the investment proportions are extreme, with several assets held in large positions. The cost of the no-shortselling constraint increases dramatically with the num...

In this paper we propose a new approach to estimating the systematic risk (the beta of an asset) in a capital asset pricing model (CAPM). The proposed method is based on a wavelet multiscaling approach that decomposes a given time series on a scale-by-scale basis. At each scale, the wavelet variance of the market return and the wavelet covariance between the market return and a portfolio are ca...

Based on a general specification of the asset specific pricing kernel, we develop a pricing model using an information process with stochastic volatility. We derive analytical asset and option pricing formulas. The asset prices in this rational expectations model exhibit crash-like, strong downward movements. The resulting option pricing formula is consistent with the strong negative skewness a...

This appendix contains tables and figures that supplement the analysis in the paper. Section A presents the asset pricing test results with equity issuance cost shocks constructed using alternative definitions of equity issuance. Section B presents the asset pricing test results with equity issuance cost shocks constructed by taking averages of portfolio-level equity issuance shocks across port...

Many tests of asset-pricing models address only the pricing predictions, but these pricing predictions rest on portfolio choice predictions that seem obviously wrong. This paper suggests a new approach to asset pricing and portfolio choices based on unobserved heterogeneity. This approach yields the standard pricing conclusions of classical models but is consistent with very different portfolio...

in this paper, the pricing of a european call option on the underlying asset is performed by using a monte carlo method, one of the powerful simulation methods, where the price development of the asset is simulated and value of the claim is computed in terms of an expected value. the proposed approach, applied in monte carlo simulation, is based on the black-scholes equation which generally def...
