How Does Consumer Spending Help the Economy? GDP, Aggregate Demand and Debt (2012)

Consumer debt can be defined as 'money, goods or services provided to an individual in lieu of payment.' Common forms of consumer credit include credit cards, store cards, motor (auto) finance, personal loans (installment loans), consumer lines of credit, retail loans (retail installment loans) and mortgages. This is a broad definition of consumer credit and corresponds with the Bank of England's definition of "Lending to individuals". Given the size and nature of the mortgage market, many observers classify mortgage lending as a separate category of personal borrowing, and consequently residential mortgages are excluded from some definitions of consumer credit - such as the one adopted by the Federal Reserve in the US.
The cost of credit is the additional amount, over and above the amount borrowed, that the borrower has to pay. It includes interest, arrangement fees and any other charges. Some costs are mandatory, required by the lender as an integral part of the credit agreement. Other costs, such as those for credit insurance, may be optional. The borrower chooses whether or not they are included as part of the agreement.
Interest and other charges are presented in a variety of different ways, but under many legislative regimes lenders are required to quote all mandatory charges in the form of an annual percentage rate (APR). The goal of the APR calculation is to promote 'truth in lending', to give potential borrowers a clear measure of the true cost of borrowing and to allow a comparison to be made between competing products. The APR is derived from the pattern of advances and repayments made during the agreement. Optional charges are not included in the APR calculation. So if there is a tick box on an application form asking if the consumer would like to take out payment insurance, then insurance costs will not be included in the APR calculation (Finlay 2009).

Consumerism is a social and economic order that encourages the purchase of goods and services in ever-greater amounts. Criticisms of consumption are already present in the works of Thorstein Veblen (1899). Veblen's subject of examination, the newly emergent middle class arising at the turn of the twentieth century, comes to full fruition by the end of the twentieth century through the process of globalization. In this sense, consumerism is usually considered a part of media culture.

The term "consumerism" has also been used to refer to something quite different called the consumerists movement, consumer protection or consumer activism, which seeks to protect and inform consumers by requiring such practices as honest packaging and advertising, product guarantees, and improved safety standards. In this sense it is a movement or a set of policies aimed at regulating the products, services, methods, and standards of manufacturers, sellers, and advertisers in the interests of the buyer.[2]
In economics, consumerism refers to economic policies placing emphasis on consumption. In an abstract sense, it is the consideration that the free choice of consumers should strongly orient the choice what is produced and how, therefore the economic organization of a society (compare producerism, especially in the British sense of the term).[3] Also this vote is not "one man, one voice", but "one dollar, one voice", which may or may not reflect the contribution of people to society.
