We use machine learning to uncover regularities in the initial play of matrix games. We first train a prediction algorithm on data from past experiments. Examining the games where our algorithm predicts correctly, but existing economic models don’t, leads us to add a parameter to the best performing model that improves predictive accuracy. We then observe play in a collection of new “ algorithmically generated” games, and learn that we can obtain even better predictions with a hybrid model that uses a decision tree to decide game-by-game which of two economic models to use for prediction.

In 1914, an accounting professor named Arthur Andersen founded a public accounting practice that became the world’s largest professional-services firm. For years preceding the Enron debacle and Andersen’s collapse, the firm had struggled to create incentives within the organization for partners to provide high-quality service, develop and sell new services, and meet the compensation expectations of various factions of partners. A years-long dispute over the division of profits between the firm’s consulting and accounting arms led to the 1998 separation of the consulting practice from the audit and tax practices. The rise, break-up and fall of Andersen underlines the importance of questions concerning incentive structures within public accounting firms in particular, and partnerships of professionals in general. This paper offers a perspective on partner compensation schemes and the accounting information systems that support them.

We examine strategic interactions between firms and planners in China, comparing behavior between: (i) students and managers with field experience with this situation, (ii) standard versus increased monetary incentives, and (iii) sessions conducted “in context,” making explicit reference to interactions between planners and managers, and those without any such references. The dynamics of play are similar across treatments with play only gradually, and incompletely, converging on a pooling equilibrium. A fivefold increase in incentives significantly increases initial levels of strategic play. Games played in context generated greater levels of strategic play for managers, with minimal impact on students.
