First Run on Wednesday – Topic: University Tuition Rates

Case Conference: Thursday and Friday Next Week

Guiding Questions:

1. EXPLAIN, USING SUPPLY AND DEMAND ANALYSIS, WHY THE PRICE OF TUITION HAS BEEN INCREASING SO RAPIDLY.

2. DO YOU THINK A) THE SUPPLY AND B) THE DEMAND FOR A POST- SECONDARY EDUCATION IS PRICE ELASTIC OR INELASTIC? JUSTIFY YOUR CHOICES AND EXPLAIN WHETHER THIS MEANS ANY GIVEN CHANGE IN SUPPLY OR DEMAND WILL HAVE A BIGGER EFFECT ON THE EQUILIBRIUM PRICE.

3. IN WHAT WAYS IS THE MARKET FOR POST SECONDARY EDUCATION DIFFERENT/SIMILAR TO A PRODUCT SUCH AS GASOLINE OR FOOD?

4. HOW MIGHT GOVERNMENTS WITH DIFFERENT ECONOMIC SYSTEMS REACT TO AN INCREASE IN THE PRICE OF TUITION?

5. WHAT OPTIONS ARE AVAILABLE TO GOVERNMENTS TO DEAL WITH THE RISING COST OF TUITION? PROVIDE EXAMPLES AND YOUR CRITIQUE OF THE APPROACH.

6.WHAT DO CONTEMPORARY AND HISTORICAL ECONOMISTS HAVE TO SAY ABOUT THE ISSUE?
