The selling price will be the same.

There is no way to answer this question without more information.

The selling price will be higher.

In the kinked demand curve model, a firm faces less elastic demand when it _______ its price than when it _______ its price.

increases, decreases

This question makes no sense since the price elasticity of demand is the same regardless of any price change.

decreases, increases

The selling price will be lower.

The supply curve of a perfectly competitive firm is the entire marginal cost curve of that firm.

True

False

In the kinked demand curve model, if the firm raises its price its total revenue _______. If the firm lowers its price its total revenue _______.

decreases, decreases

decreases, increases

increases, decreases

If you look at the graph of a perfectly competitive firm and see that it has an economic profit, you know the graph is of the short run. However, when you look at the graph of a monopoly and see that it has an economic profit, you are unable to tell if the graph is of the short run or the long run.

True

False

When a firm has increasing returns to scale its average total cost _______.

remains constant

decreases

increases

increases, increases

The firm’s total cost is greater than its total revenue.

The firm’s opportunity cost is larger than its accounting profit.

The firm is definitely in the long run.

The firm has an economic loss.

A store decreased its prices by 5% and the quantity demanded increased by 7.5%. The price elasticity of demand is _______ (in absolute value) and the demand is _______.
