Each company is controlled by a team of students who decide which markets to enter, how much capacity to build, when to reduce capacity or exit a market, what quantities to produce and what prices to charge. In each period, each company submits a strategy specifying these variables and can also submit a public statement. The markets then operate for the period. At the end of each period, every team receives a market update --- which has public information on prices, capacities, and approximate market sales, as well as any public statements --- and a company update --- which has the relevant income statement and balance sheet information, such as capacity, production, sales, inventory, capacity costs, variable costs, interest paid or earned on cash balances, and cash position.
An important aspect of the Competitive Strategy Game is the role of information. Some data are public information, such as all firms' prices and production capacities, the degree of substitutability across brands within each market, and some basic information about demand. Other variables are known only with some noise. For instance, each firm knows its own sales in each market, but the total sales in each market is known publicly only with a degree of error. Similarly, no firm knows the production costs of its competitors with certainty, but it does know the distribution from which costs are drawn.
Each firm begins with a cash reserve and makes strategic decisions in an attempt to maximize the value of the firm. The CSG is useful for teaching basic economic concepts such as sunk, fixed, and marginal costs, the opportunity cost of investment, firm- and market-elasticities of demand, and product differentiation. It also is immediately applicable to discussions of entry deterrence, first-mover advantages, preemption, competitive advantage, predation, oligopoly coordination, multimarket contact, signalling, information asymmetries, and end game issues in finitely repeated games.
The Game is configured with four output options: (1) Using the
CSG
web page, (2) ascii format for an HP-compatible printer, (3) ascii
format for email transmission, (4) TeX format. In a typical one-semester
course, the game can be played for 15-20 periods, slightly less for a one-quarter
course.
The CSG has been used in undergrad, MBA, or Ph.D. level courses
at more than 25 universities and colleges in 7 countries. Here is
a list of those
institutions. In advanced courses, "data" from the game can be
used as the basis for estimating demand functions, Nash equilibria, and
competitive behavior. Sample homework assignments that lead students throught
these exercises are available.
