Ronen Gradwohl

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. Most recently his research has focused on issues of privacy and transparency.

Print Teaching
Full-Time / Part-Time MBA
Business Analytics I (DECS-430-5)
This course was formerly known as DECS 430-A/DECS 430-B
This course is equivalent to the MMM core course MMM Business Analytics (DECS-440) 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.

Full-Time students are required to complete the Business Analytics Prep Course

Part-Time Students are required to complete the Business Analytics Prep Course

Foundations of Managerial Economics I: Static Decision Models (MECS-460-1)
Basic models used to analyze optimal decision-making in economics and operations research. Topics include basic assumptions and decision analysis, linear programming and duality, risk aversion and risk bearing, bidding in auctions, Bayesian inference, and Markov decision problems.

Foundations of Managerial Economics I: Game Theory (MECS-460-3)
Conflict and cooperation among rational decision makers in economic, political, and social systems. 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. Taught in a self-contained manner but closely coordinated with ECON 410-3. Prerequisites: Knowledge of probability theory and elementary linear algebra; simultaneous enrollment in ECON 410-3 or permission of the instructor.
