The Black-Scholes vs. the Merton jump-diffusion model applied to selected WIG20 companies in the year 2011 Rafał M. Łochowski Warsaw School of Economics e-mail: rlocho@sgh.waw.pl Abstract Two classical models - the Black-Scholes model and the Merton jump-diffusion model of the evolution of stock prices are considered. The Merton model, developed by Robert C. Merton in 1974, is a widely used credit risk model. Analysts and investors utilize the Merton model to understand how capable a company is at meeting financial obligations, servicing its debt, and weighing the general possibility that it will go into credit default.

The Merton model uses the Black-Scholes-Merton option pricing methods and is structural because it provides a relationship between the default risk and the asset (capital) structure of the firm. PROBABILITY DISTRIBUTION In the world of statistics, we are introduced to the concept of probability.On page 146 of our text, it defines probability as "a value between zero and one, inclusive, describing the relative possibility (chance or likelihood) an event will occur" (Lind, 2012). The Merton Model • Merton’s assumptions: 1. One zero-coupon bond with face value F and maturity T 2. Firm value, V, geometric Brownian motion 3. Other Black-Scholes-Merton assumptions • Equity, E, is a call option on V with strike equal to F and maturity of T 2) The Model: The Merton model generates the probability of default for each firm in the sample at any given point in time.

π Merton is the expected default frequency in percent and is given by Equation . naïve σ V is calculated by Equation , and the firm's equity return from the previous year, r it−1, is used as a proxy for the firm's
2) The Model: The Merton model generates the probability of default for each firm in the sample at any given point in time. To calculate the probability, the model subtracts the face value of the firm’s existing debt from an estimate of the future market value of the
