In this communication, we develop suitable valuation techniques for a with-profit/unitized with profit life insurance policy providing interest rate guarantees, when a jump-diffusion process for the evolution of the underlying reference portfolio is used. Particular attention is given to the mispricing generated by the misspecification of a jumpdiffusion process for the underlying asset as a pu...

Valuation and parities for both European-style and American-style exchange options are presented in a general financial model allowing for jumps, the possibility of default, and “bubbles” in asset prices. The formulas are given via expectations of auxiliary probabilities using the change-of-numéraire technique. Extensive discussion is provided regarding the way that folklore results such as Mer...

This thesis consists of two related parts. The first part develops non-parametric freight rate and scrap value models for the product tanker market. Monte Carlo simulations are used to calculate the value of the vessel as the present value of future cashflow and perform sensitivity analysis with respect to input parameters such as vessel age, freight rate volatility, and scrap price. The second...

This study investigates the effects of information asymmetries and asset valuation model differences (investor heterogeneity) between foreign domestic investors on their distinct portfolio holdings in an emerging market setting. I argue that asymmetry investor heterogeneity views significantly interact explaining different allocation decisions investors. Employing a large dataset from Turkey, f...

A collocation method based on modified cubic B-spline functions has been developed for the valuation of European, American and barrier options of a single asset. The new approach contains discretization of temporal derivative using finite difference approximation of and approximating the option price with the modified B-spline functions. Stability of this method has been discussed and it is sho...

We establish necessary and sufficient conditions for a linear taxation system to be neutral − within the continuous-time “no arbitrage” model − in the sense that asset valuation is invariant to the process for tax rates and choice of realization dates as well as immune to timing options attempting to twist the time profile of taxable income through wash sale transactions. We also demonstrate th...

This paper studies warrant valuation using a reduced-form model. Analogous to the credit risk literature, structural models require complete information about the asset value process and the firm’s liabilities. In contrast, reduced-form models require only information about the firm’s stock price process. We introduce a reduced-form model where the warrant holder is a price taker, and we relate...

Traditionally, the Net Present Value method is used to compare diverging investment strategies. However, valuating crypto-projects with fiat-based currency is confusing due to extreme coin appreciation rates as compared to fiat interest rates. Here, we provide a net present value method based on using crypto-coin as the underlying asset. Using this method, we compare HODL vs. mining, we also pr...
