H-o approach was primarily supply-oriented because it focused on factor endowments and factor intensities. The Linder theory postulates that tastes of consumers are conditioned strongly by their income levels; the per capita income level of a country will yield a particular pattern of tastes. (Note that Linder is concerned only with manufactured goods; he regards Heckscher-Ohlin as fully capable of explaining trade in primary products. These tastes of"representative consumers in the country will in turn yield demands for products, and these demands will generate a production response by firms in that country. Hence, the kinds of goods produced in a country reflect the per capita income level of that country. This set of particular goods forms the base from which exports emerge.
