Closed-form convexity and cross-convexity adjustments for Heston prices

We present a new and general technique for obtaining closed-form expansions for prices of options in the Heston model, in terms of Black–Scholes prices and Black–Scholes Greeks up to arbitrary order. We then apply the technique to solve, in detail, the cases for the second-order and third-order expansions. In particular, such expansions show how the convexity in volatility, measured...

Entrepreneurial Spawning and Firm Characteristics

Our model accounts for much of the empirical evidence relating to the relation between spawning and firm characteristics. Firms that have higher patent quality spawn more, as do firms that...

An agent can choose to forego bene ts from side opportunities and to instead provide bene ts to the principal. In return, the principal o¤ers rewards.

Specificity of Occupational Training and Occupational Mobility: An Empirical Study Based on Lazear's Skill-Weights Approach

According to standard human capital theory, firm-financed training cannot be explained if the skills obtained are general in nature. Nevertheless, in German-speaking countries, firms invest heavily in apprenticeship training although the skills are assumed to be general. In our paper, we study the extent to which apprenticeship training is general at all and how specificity of...

Is there a U-shaped relation between competition and investment?

We consider a two-stage game with cost-reducing investments followed by a linear differentiated Cournot duopoly. With competition inversely parameterized by the extent of product differentiation, investment in the subgame perfect equilibrium is typically minimal for intermediate levels of competition. Laboratory experiments partly confirm the U-shape in a reduced one-stage version of...

Optimalwertfunktion und Einhüllendensätze

Bei Optimierungsmodellen in den Wirtschaftswissenschaften werden häufig gewisse Problemdaten als Parameter (exogene Variablen) aufgefasst, sodass es wichtig ist zu untersuchen, wie die Lösungen und der Optimalwert von den Parametern abhängen. Von besonderem Interesse sind sogenannte Einhüllendensätze, die Bedingungen für die Differenzierbarkeit der Optimalwertfunktion eines...
