| deepseekr1 | The price increase of polyester pants, a substitute for denim jeans, leads consumers to shift their demand toward jeans. This substitution effect **increases the demand for jeans**, causing the demand curve to shift right. In a market with upward-sloping supply and downward-sloping demand, this results in **higher equilibrium price and quantity** for jeans. Supply remains unaffected because the price change of a substitute does not alter production costs or supply conditions for jeans. **Answer:** D. demand rises, increasing the price and increasing the quantity. |

| kimi | D. demand rises, increasing the price and increasing the quantity. When the price of a substitute good (in this case, polyester pants) rises, consumers will likely switch to the alternative good (denim jeans), assuming it remains at the same price. This shift in preference increases the demand for denim jeans. In a market in equilibrium, an increase in demand will lead to an increase in both the price and the quantity sold, assuming supply is relatively inelastic in the short run. |

| wenxinyiyan | D Explanation: The question asks about the effect on the denim jeans market when the price of polyester pants, a substitute good, rises. Key Concepts: 1. Substitute Goods: Goods that can be used in place of each other. For example, denim jeans and polyester pants are substitutes because consumers might choose one over the other based on price, quality, or personal preference. 2. Market Equilibrium: A state where the quantity demanded of a good or service is equal to the quantity supplied at a given price. 3. Changes in Demand and Supply: Changes in the price of substitute goods affect demand, not supply. Analysis: * When the price of polyester pants rises, consumers are likely to look for alternatives, such as denim jeans. * This increase in consumer preference for denim jeans leads to an increase in demand for denim jeans. * An increase in demand, assuming supply remains unchanged in the short run, will lead to an increase in the equilibrium price and quantity of denim jeans. Conclusion: The correct answer is D. When the price of polyester pants, a substitute good, rises, demand for denim jeans rises, increasing the price and increasing the quantity in the denim jeans market. |
