Early exercise decision in american options with dividends, stochastic volatility and jumps

Using a fast numerical technique, we investigate a large database of investor suboptimal nonexercise of short maturity American call options on dividend-paying stocks listed on the Dow Jones. The correct modelling of the discrete dividend is essential for a correct calculation of the early exercise boundary as confirmed by theoretical insights. Pricing with stochastic volatility and...

Entrepreneurial orientation and SME performance across societal cultures: An international study

The concept of entrepreneurial orientation (EO) is universally applicable, and many empirical studies report a positive relationship between EO and performance in different national contexts. Empirical research, however, scarcely addresses which country-level contingencies affect the EO–performance link. Building on two secondorder factors of societal culture—performance-based...

Customer-specific synergies and market convergence

We use an analytical model to study the effects of customer-specific synergies – i.e. synergies that arise when firms sell multiple products to the same customers. At the firm level, we show that the profitability of a customer-specific synergy depends upon cross-market correlation of customer preferences, differs when the synergy is cost-based versus differentiation-based, and can...

What does it mean to be responsible? Addressing the missing responsibility dimension in ethical leadership research

This paper extends research on ethical leadership by proposing a responsibility orientation for leaders. Responsible leadership is based on the concept of leaders who are not isolated from the environment, who critically evaluate prevailing norms, are forward looking, share responsibility, and aim to solve problems collectively. Adding such a responsibility orientation helps to...

Lipschitz and Hölder stability of optimization problems and generalized equations

This paper studies stability aspects of solutions of parametric mathematical programs and generalized equations, respectively, with disjunctive constraints. We present sufficient conditions that, under some constraint qualifications ensuring metric subregularity of the constraint mapping, continuity results of upper Lipschitz and upper Hölder type, respectively, hold. Furthermore, we...

Financial regulation and social welfare: the critical contribution of management theory

While many studies explain how social science theories shape social reality, few reflect critically on how such theories should shape social reality. Drawing on a new conception of social welfare and focusing on financial regulation, we assess the performative effects of theories on public policy. We delineate how research that focuses narrowly on questions of efficiency and...

The stability and change of value structure and priorities in childhood: A longitudinal study values in childhood

This longitudinal study explores the stability and change of values in childhood. Children's values were measured in Poland three times (with one-year intervals) using the Picture Based Values Survey (PBVS-C; Döring, Blauensteiner, Aryus, Drögekamp, & Bilsky, 2010), developed to measure values differentiated according to the circular model of Schwartz (1992). 801 children (...

The importance of suspense and surprise in entertainment demand: Evidence from Wimbledon

This paper empirically examines how suspense and surprise affect the demand for entertainment. We use a tennis tournament, the Wimbledon Championships, as a natural laboratory. This setting allows us to both operationalize suspense and surprise by using the audience's beliefs regarding the outcome of the match and observe the demand for live entertainment using TV audience...

Empathy and perspective-taking: examination and comparison of strategies to reduce weight stigma

Considerable evidence indicates that individuals with obesity are vulnerable to stigma and discrimination. However, comparably less research has examined strategies to reduce weight bias, and the existing evidence is mixed. To help clarify these findings and incorporate prejudice-reduction interventions that have been successfully applied to other stigmatized groups (i.e., empathy-...

Does economics and business education wash away moral judgment competence?

In view of the numerous accounting and corporate scandals associated with various forms of moral misconduct and the recent financial crisis, economics and
business programs are often accused of actively contributing to the amoral decision making of their graduates. It is argued that theories and ideas taught at universities engender moral misbehavior among some managers, as...

We use data on 330 researchers from business and economics in Germany, Austria and the German-speaking part of Switzerland and measure appointment success by (a) the time it takes a young researcher to get tenure and by (b) whether the researcher succeeded in getting tenure...
