When the demand curve shifts, the change in equilibrium price will be larger the more elastic the supply curve. (a) True (b) False

Suppose price elasticity of demand is greater than 1. Which of the following example is correct? (a) If I increase price of oranges by 1%, sales of oranges increase by more than 1%. (b) If I increase price of oranges by 1%, sales of oranges decline by less than 1%. (c) If I increase price of oranges by 1%, sales of oranges increase by less than 1%. (d) If I increase price of oranges by 1%, sales of oranges decline by more than 1%. Consider the following table: Table 2.7 Market Size and Average Winning Percentage in the National Basketball Association: 2004-05 to 2015-16 Variable Market size Coefficient -0.0021 t-Statistic -0.67 (a) Market size impacts average winning percentage negatively and it is statistically sig nificant. (b) Market size impacts average winning percentage negatively but it is statistically in- significant. (c) Average winning percentage is positively correlated with market size and statistically significant. (d) Market size impacts average winning percentage…
