Game theory studies strategic decision-making that is situations where the outcome does not only depend on your own actions but also that of others. It has significantly changed how business strategists, economists, and policymakers think about problem-solving and has become an indispensable tool in economic modelling, strategy analysis, and negotiation techniques. As strategic decision-making arises naturally in many contexts, game theory has influenced many other fields, such as political sciences, biology, and computer sciences. In this module, core concepts and ideas will be illustrated with the help of many everyday examples and economic and business applications, ranging from how groceries are priced to trade wars and political conflicts. This module will boost your strategic thinking to become a successful manager or influential policymaker.
