This simple classroom experiment demonstrates many of the behavioral phenomena associated with the voluntary provision of a public good. The mechanics of the game are explained in detail and complete instructions are provided, as well as suggestions for follow-up lectures. Influences such as anonymous voting, persuasion, returns to free-riding, and duration of association can be explored in connection with concepts of incentives, individual rationality and group welfare. A number of variations and extensions can be used to incorporate prisoners' dilemmas, incentive compatible mechanisms, negative externalities, and Coasian bargaining.

Nonparametric procedures are used to compare technological change in SIC 2011, meatpacking, and SIC 2015, poultry slaughter and processing. There has been a greater increase in total factor productivity in poultry than in the red meats. Evidence also suggests recent differences in the bias of this technological change, with production changes being labor using in poultry and biased towards greater efficiency in the use of live animal inputs in meatpacking.
