Bond Trader is a simulation designed to teach students the foundational themes of introductory finance in an engaging but simple simulated securities market. Bond Trader provides a powerful context for teaching such foundational themes as time value of money, equilibrium-required return, the yield curve, market efficiency and the pricing of information, financial substitutes and arbitrage-based security pricing, bond math, and financial market mechanics. In the simulation, students compete in teams or individually to maximize the value of a trading portfolio by choosing when to take positions in bond securities and when to hold cash. To increase engagement, student performance is ranked against their peers. Students make buy-and-sell decisions for each weekly trading periods of 10-15 seconds. Students experience the impact of the collective market decisions as bond prices dynamically evolve based on the aggregate buy-and-sell order flow from students and computer traders in the market, using an internet-based interface. Bond Trader has been used effectively in Darden's first-year corporate finance course and is designed to work as an effective introduction to any standard corporate finance or investments curriculum.
