Answer to Question 2
Marketers have always talked about goods and services being on a continuum. Some goods seem to be pure goods (e.g., blue jeans, DVDs), and some services seem to be pure services (e.g., consulting, rock concerts). Other purchases seem to be a mix of good and service (e.g., car rentals). The key seems to be the extent to which the purchase is tangible. Services differ from goods in other ways. Services are simultaneously produced and consumed. Whereas goods can be manufactured and then inventoried in distribution warehouses, most services have to be created on the spot in the presence of the customer. For example, you have to be present to have your hair cut. This inseparability of production and consumption inevitably results in more perishable services. The final major difference between goods and services is that services are said to be more variable.
