This paper develops a new pricing model for American-style indexed executive stock options. We rely on a basic model framework and an indexation scheme first proposed by Johnson and Tian (2000a) in their analysis of European-style indexed options. Our derivation of the valuation formula...

This paper examines the use of stock options by Australian IPOs. Stock options in this setting exhibit heterogeneity of ‘in the moneyness' attributes. We can therefore identify incentive ‘out of the money' options and reward ‘at or in the money' options and study their usage. The setting...

We examine the ex-ante optimality of repricing of executive stock options while considering the tax effects of new accounting rules associated with traditional repricing. Although there has been a body of empirical literature on repricing, the optimality of repricing after considering the...

We investigate the impact of independent valuation specialists on the downward bias of pre-initial public offering employee stock option valuations. Undervalued stock price estimates underlying firms' option grants produce option valuations that overstate earnings and provide employees with deep...

Option prices embed predictive content for the outcomes of pending mergers and acquisitions. This is particularly important in merger arbitrage, where deal failure is a key risk. In this paper, I propose a dynamic asset pricing model that exploits the joint information in target stock and option...

This paper reconsiders American and Bermudan callable bonds and highlights their key differences. We illustrate how the level of interest rate critical for calling Bermudan Callable Bonds (BCBs) can differ from those critical for calling American Callable Bonds (ACBs). We also stress that it is...

In this paper a joint capital asset pricing model and option pricing model is considered and applied to the derivation of an equity's value and its systematic risk. We first analyze the propreties of the two models and present some newly found properties of the option pricing model. We then...

This article models mergers as exchange options where acquirers offer stocks and/or cash to target firms in exchange of acquiring some shareholding in target firms. Mergers analysed in this article happen between homogeneous entities. The B-S and Margrabe models are used to price cash and stocks...

In this paper we review the pricing and model calibration of Credit Default Swaps referring to both the International Swaps and Derivatives Association (ISDA) CDS contract and credit model standardization guidelines. Furthermore we provide an Excel pricing workbook to supplement the materials...
