Unit 2 - Understanding Elasticity in Economics

What does the term 'elasticity' signify in economics?

• The fluctuation of stock market prices

• The responsiveness of quantity demanded or supplied to changes in price or income

• The rigidity of market conditions

• The change in government economic policies

How does the concept of elasticity help in understanding economic theories?

• By understanding the responsiveness of demand and supply to changes in price and income

• By predicting future economic recessions

• By determining the best taxation policies

• By measuring the volatility of stock markets

What is the price elasticity of demand for a product that remains unchanged in quantity demanded regardless of price changes?

• Infinity

• Zero

• One

• Undefined

Which curve represents a situation where the price elasticity of demand is infinity?

• Upward sloping demand curve

• Downward sloping demand curve

• Horizontal demand curve

• Vertical demand curve

At what point on a linear demand curve is the price elasticity of demand equal to one?

• At the midpoint

• At the origin

• At the price axis

• At the quantity axis

How is total revenue affected in the elastic portion of a demand curve when price decreases?

• Total revenue decreases

• Total revenue remains unchanged

• Total revenue increases

• Cannot be determined

What happens to total revenue as we move down the inelastic portion of a linear demand curve?

• It increases

• It decreases

• It first increases, then decreases

• It remains constant

What is the price elasticity of supply when quantity supplied is completely unresponsive to price changes?

• One

• Undefined

• Zero

• Infinity

What does a perfectly elastic supply curve look like?

• Horizontal line

• Upward sloping line

• Downward sloping line

• Vertical line

For a good with unit elastic supply, how does quantity supplied respond to a percentage change in price?

• Quantity supplied changes by a smaller percentage

• Quantity supplied does not change

• Quantity supplied changes by the same percentage

• Quantity supplied changes by a greater percentage
