Personal information

Research

Jost's research focuses on strategic leadership, which is the study of how top executives and their teams shape organizational outcomes. Within this field, he pursues two main streams: the effects of leadership team composition on firm performance, and executive decision-making under conditions of risk and uncertainty. A methodological commitment to causal identification using quasi-experimental designs (instrumental variable design, regression discontinuity design) runs through both streams.

His work on leadership team composition examines how the characteristics and diversity of boards and top management teams affect outcomes such as financial performance, risk-taking, and pay equity. His work on risk and uncertainty investigates how leaders anticipate, assess, and respond to threats, connecting behavioral decision-making research to organizational risk and crisis management.

Alongside these substantive streams, he is building a program on research credibility in management, addressing replicability, methodological rigor, and the development of tools and standards for more credible evidence in the field.
