We develop routines in quot;Mathematicaquot; for pricing various European and American options using the binary option model and Monte Carlo methods. As might be expected, quot;Mathematicaquot; permits parsimonious programming of the option pricing expressions

A bond's expected return (EBR) is the ex-ante internal rate of return of the bond's expected future cash flows, whereas a bond's yield to maturity (YTM) is the internal rate of return of its promised future cash flows. In this paper we estimate the EBR for a sample of bonds using rating...

The paper presents a method for calculating the cost of equity capital for the non-marketable securities of private firms and its difference from the cost of equity capital of an all else equal public firm (the private firm premium). The method is based on a theoretical framework that assumes...

We estimate the value of restricted stock (RS) grants to non-executive employees using a unique proprietary database by calibrating theoretical models that account for the non-marketability of securities and the potential effects of the employee's non-diversification. The calibration results...

The subject here is construction of the covariance matrix for portfolio optimization. In terms of the ex post standard deviation of the global minimum-variance portfolio, there is no statistically significant gain in using more sophisticated shrinkage estimators rather than simpler portfolios of...

We adapt the Benninga-Helmantel-Sarig (2005) framework to value employee stock options (ESOs). The model quantifies non-diversification effects, is computationally simple, and provides an endogenous explanation of ESO early-exercise. Using a proprietary dataset of ESO exercise events we measure...

We present a discrete time model of expected bond returns (EBR). These are ex-ante expectations implied by the market prices and the data set available when bond prices are quoted. The model can be used to estimate the rating-adjusted EBR, its risk premium components, including a certainty...

The classical assumptions of the Capital Asset Pricing Model do not ensure obtaining a tangency (market) portfolio in which all the risky assets appear with positive proportions. This paper gives an additional set of assumptions that ensure obtaining such a portfolio. Our new set of assumptions...
