For each of the pair below, indicate when you, as a seller, would use price discrimination method. For your answer for each pair, please provide very brief explanation of your choice (Each explanation should not exceed more than 30 words): A good that has close substitutes vs a good that has close complements. I would use price discrimination for a good that has a close substitute since the market will be competitive and buyer could see a benefit in switching. An acyclic good vs a noncyclic good. An acyclic good gives the seller the ability to use price discrimination to take advantage of seasonality or demand swings. A good that you are planning to sell only in the short run vs a good that you are planning to sell in the long run. Short term sales can be used to A good whose demand can be accurately forecasted vs a good whose demand forecast is uncertain. The good whose demand can be forecasted can allow for accurate planning A good which has a high positive advertisement elasticity vs a good that has a low positive advertisement elasticity.
