4․2 Calculating Cross-Price Elasticity
Cross-price elasticity is calculated using the formula: (percentage change in quantity demanded of good A) / (percentage change in price of good B)․ A positive result indicates goods are substitutes‚ while a negative result suggests complements․ Worksheets often provide data on price and quantity changes‚ guiding students through calculations․ Answer keys offer step-by-step solutions‚ ensuring accurate interpretations․ This concept is vital for understanding market interactions and strategic pricing‚ with practical applications in business and policy-making․
Price Elasticity of Supply
Price elasticity of supply measures how quantity supplied responds to price changes․ Factors like production costs and time lags influence elasticity․ Worksheets provide exercises for calculating supply elasticity using the midpoint method‚ ensuring accurate interpretations of elastic and inelastic supply scenarios․
5․1 Factors Influencing Supply Elasticity
Supply elasticity is influenced by production costs‚ technology‚ and time․ Worksheets highlight that firms with low production costs often have higher elasticity․ Time factors‚ like short-run vs․ long-run‚ also play a role․ For instance‚ in the short run‚ firms may face rigid production capacities‚ making supply inelastic․ In contrast‚ the long run allows for adjustments‚ increasing elasticity․ Answer keys provide examples‚ such as agriculture‚ where seasonal fluctuations affect supply responsiveness․ These exercises help students understand how resource availability and market dynamics shape elasticity outcomes․
5․2 Calculating Price Elasticity of Supply
Price elasticity of supply measures how quantity supplied responds to price changes․ The formula is the percentage change in quantity supplied divided by the percentage change in price․ A higher value indicates greater elasticity․ Worksheets often include problems where students calculate elasticity using given price and quantity data․ For example‚ if a 10% price increase leads to a 5% increase in supply‚ elasticity is 0․5․ Answer keys provide step-by-step solutions‚ emphasizing interpreting results to determine if supply is elastic or inelastic․
