Pushing models to extremes can expose output biases that stem from underlying assumptions. In the case of industry standard option valuation models, long term, high volatility securities provide a stress test vehicle. For instance, in evaluating a stock with 60% volatility, industry standard...

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...

Existing dynamic capital structure models are based on single triggers determining bankruptcy, mainly over-indebtedness or illiquidity. The latter one tends to underestimate optimal capital structures by ignoring capital providers' flexibility to inject fresh money. The former one leans towards...

This study incorporates the overextrapolation belief into the classic real options model. Using the stochastic dynamic programming method, we obtain the semiclosed-form solutions for the optimal investment and valuation of real options and the welfare loss owing to overextrapolation. The...

One reason for the phenomenal success of options is the fact that they can be priced. Pricing usually means that there is an active and a liquid market with many buyers and sellers that generate a continuous flow of prices for a specific instrument. However, the pricing of options goes beyond...

We show that if the discounted Stock price process is a continuous martingale, then there is a simple relationship linking the variance of the terminal Stock price and the variance of its arithmetic average. We use this to establish a model-independent upper bound for the price of a continuously...

The pricing of vanilla options on underliers with cash dividends is a surprisingly contentious and active research subject, for both European or American exercise style. Neither on the listed options side (calls and puts) nor on the flow/structured side of longer-term vanillas or light exotics...

This is the first paper to calculate and analyze option-implied dividends for individual US companies, while accounting for the early exercise premium. These firm-level implied dividends show substantial variation relative to actual dividends over time as well as in the cross-section. Implied...
