Document Summary

3. 1 week 5: elasticity: know that elasticity is the percentage change in quantity divided by the percentage change in price. Using derivatives, this can be written as =dq. p/dp. q. Elasticity, de ned this way, is negative and ranges from. First, because elasticity involves percentage changes, it is invariant to the unit of measurement. Second, it turns out to have a relationship with marginal revenue which turns out to be very useful when analysing a monopoly. See the part on monopoly below: be able to work through the tutorial on elasticity and the relevant problems from the quiz. 3. 2 week 6: market experiment: you will not be tested on the online market experiment that we did in class. 3. 3 week 7: perfect competition: know the key assumptions underlying a perfectly competitive market, be able to distinguish between the short run and the long run. In the short run, some factors of production cannot be varied, and thus xed costs are sunk.

In this question, we will determine the price elasticity of demand using both the coefficient of elasticity and the total revenue test.

Use the demand schedule in the table below to answer the following questions.

Quantity Demand	Price
10	200
20	150
30	100
40	50
50	25

a) Calculate the total revenue for each row in the demand schedule. indicate whether total revenue increases or decreases between each row int eh demand schedule. use the total revenue test to classify each price/quantity change as elastic, inelastic, or uni-elastic.

b) calculate the own price-elasticity coefficient for each row in the demand schedule. use the coefficients you calculate to classify each price/quantity change as elastic, inelastic, unit elastic.

in your answer it will be useful to recall that the midpoint formula for percentage change is:

%change midpoint = (final - initial) / ((finial + initial)/2)

and own price elasticity can be calculated by using the formula

Ed= (percentage change in quantity demand of product x) / (percentage change the in the price of product x)
