Topics include consumers' non-homothetic preferences as a driving factor for intra-industry trade; utility maximization of consumers; profit maximization of firms; the effects of income levels on consumer choices; product quality; and transportation costs in Krugman's home market effect which compares the costs of domestic versus foreign trade.
