Abstract

Using quantum modeling, we propose a novel approach to reputational risk management arguing that taking care of corporate reputation can be considered a coalitional strategy framed into a quantum game theory schema. Following a stochastic mechanics approach, and assuming that the revenues of a firm can be modeled as an Ornstein–Uhlenbeck process represented by the well-known Langevin equation for the diffusion of a particle with unit mass under non-linear friction, we offer a mathematical derivation for the discount rate of a firm that does not manage its reputational risk and for a company that optimally manages its reputational risk. By comparison, we derive an analytical expression for the reputational risk premium. Our approach provides useful managerial and financial implications, suggesting that the use of the quantum ideology may result useful in enlarging the body of knowledge of corporate management.

5. Conclusions

We offer an innovative methodological approach to the analysis of reputational risk based on quantum modeling. Previous researchers have contextualized corporate social responsibility related issues into a game theory scenario. As an extension of these analyses, we propose that reputational risk management can be framed into a quantum game theory schema, taking advantage of the ideology and formalism from quantum modeling. In this sense, it is argued that taking care of corporate reputation can be assimilated to a coalitional strategy into a quantum market game. In addition, and following a stochastic mechanics approach, we model the revenue of a company as a stochastic process using the Ornstein–Uhlenbeck approach represented by the Langevin equation for the diffusion of a particle with unit mass under non-linear friction. Exploiting stochastic calculus, partial differential equations and dynamic optimization, we supply a mathematical derivation of the discount rate for a company that does not manage reputational risk management. In addition, by incorporating a measure of the reputational effort, we derive the discount rate for a company that optimally manages its reputational risk. Finally, we calculate an analytic expression for a reputational risk premium.
