Barter Trading as a Microeconomics Teaching Device

Karpoff reports on a “barter trading game” in which students exchanged real goods over a period of seven weeks with different market constraints imposed each week. Student comments about the exercise were favorable.     

Comment

How well does competitive theory explain the outcome in experimental markets. The authors examined the results of a large number of classroom trading experiments that used a pit-trading design found in Experiments with Economic Principles, an introductory economics textbook by Bergstrom and Miller. They compared experimental outcomes with predictions of competitive-equilibrium theory and with those of a simple profit-splitting theory. Neither theory was entirely successful in explaining the data, although in the first rounds of trading there was significant profit splitting and, as traders became more experienced, outcomes were closer to those predicted by competitive theory.     

Using a Simple Contest to Illustrate Mechanism Design

This article describes a simple classroom activity that illustrates how economic theory can be used for mechanism design. The rules for a set of contests are presented; the results typically obtained from these contests illustrate how the prize structure can be manipulated in order to produce a particular outcome. Specifically, this activity is designed to show how changing the prize structure can impact both the contestants’ average efforts and the effort level of the hardest-working contestant. The activity can be run in a 50-minute class, has instructions that fit on a single piece of paper, and, although it can be run in large classes, requires only six students.

Introducing a Learning Portfolio in an Undergraduate Financial Accounting Course

This paper evaluates changes made to the internal assessment component of a third year financial accounting course at a university in New Zealand. A learning portfolio was designed to supplement existing coursework. The aim was to engender in students a deep rather than a surface approach to learning. As a record of the students' learning, the learning portfolio was an attempt to produce an innovative development in the assessment of what was a traditionally taught financial accounting course. Within their learning portfolios, students were required to complete a number of tasks, each aimed at improving critical thinking skills and creativity. Students were also required to maintain a personal or reflective section aimed at personalising and deepening the quality of their learning.
