MANAGERIAL ECONOMICS & DECISION SCIENCES
Assistant Professor of Managerial Economics & Decision Sciences

Print Overview
Ronen Gradwohl joined the MEDS department at the Kellogg School of Management in 2009 after obtaining his Ph.D. in computer science and applied mathematics from the Weizmann Institute of Science. Professor Gradwohl’s research focuses on strategic interactions in environments characterized by uncertainty about timing and communication, by the presence of irrational players, and by the possibility of collusion. His current research projects include a study of the properties of equilibria in such environments and the design of mechanisms in a distributed setting with faults. Additionally, he is interested in the design of distributed and cryptographic protocols resilient against both rational and adversarial manipulation.

Full-Time / Part-Time MBA
Business Analytics I (DECS-430-A)
Analytics is the discovery and communication of meaningful patterns in data. This course will provide students with an analytics toolkit, reinforcing basic probability and statistics while throughout emphasizing the value and pitfalls of reasoning with data. Applications will focus on connections among analytical tools, data, and business decision-making.

Students are required to complete the Business Analytics Prep Course

Doctoral
Foundations of Managerial Economics I: Static Decision Models (MECS-460-1)
This course provides essential tools for those planning to create or apply economic theory. The course can be divided very broadly into feasibility, optimization, and fixed-point theory. More specifically, it covers linear programming, Kuhn-Tucker conditions, Brouwer and Kakutani fixed-point theorems, and supermodularity, while illustrating uses in finance, game theory, general equilibrium, and matching.

Foundations of Managerial Economics I: Game Theory (MECS-460-3)
This course covers conflict and cooperation among rational decision makers in economic, political and social systems. Topics include games in extensive, normal and characteristic function forms; Nash equilibrium and refinements; Bayesian games; infinitely repeated games; stochastic games; Nash bargaining solution; and cooperative games. The course is self-contained but closely coordinated with ECON-410-3. Prerequisite: Knowledge of probability theory and elementary linear algebra; simultaneous enrollment in ECON-410-3 or permission of the instructor.
