Teaching Results

This course aims at the presentation of game theory as a analytical toolkit of modern microeconomics. Game theory is founded on the axiomatization of decision theory, which extends to incorporate decision makers that interact each other. In fact, objective of game theory is to investigate the role of this interaction in the formation of decision outcomes.

The inefficiency of modern markets in real economy as well as in finance is attributed to a large extent to the strategic behavior of economic agents, hence game theory becomes a very fundamental tool for the understanding and prediction of market conditions. Upon completion of this course students will be able to understand the strategic behavior in the economy and to interpret various economic phenomena with strategic interaction.
