Answer:
(1.)Buyer: means a person who buys or agrees to buy goods. Seller: means a person who sells or agrees to sell goods.
(2.)According to the business theory of buyer–seller similarity proposed by Lichtenthal and Tellefsen (2001), when a salesperson shares similar traits with a buyer, such as age, heights and product preferences, the salesperson can have a higher chance of building rapport with the buyer and close the sales.
(3.)The biggest difference between a buyer's market and a seller's market lies in the power position. Buyer's markets are more favorable to buyers – more inventory, lower prices – so they have more “power” than sellers.
