Finance is the study of economic decisions involving time and uncertainty. Understanding outcomes as a consequence of competitive interactions of decision makers is central to this field. Many key insights into modern finance such as market efficiency, asset pricing, market trading and option pricing rely on the forces of competition to realize predictions about prices and other financial outcomes. Creating a rigorous market atmosphere in the classroom and providing students with an opportunity to experience and understand the intuition required to achieve equilibrium outcomes and optimum decision rules in financial markets is a challenge for teachers.
