Answer 1

A) Household is a group of people who make economic decisions together. In economic theory households have two roles: they enter the market as buyers or consumers of goods and services produced by firms and they provide for factor inputs to firms in order to produce those goods and services. The term household" is used in national income analysis, supply and demand analysis it is replaced by the term "consumer".
6) Black economy is nonmarket economic activity which is not included in. the national income accounts, either because such activity does not pass through the market or because it is illegal. Illegal economic activity may exist in the usual price system which is determined by demand and supply. Examples may be the purchase and sale of illegal drugs in the street, or alcohol during the US prohibition era of the 1920s. However, some nonmarket activity is carried out for non-profit-making purposes.
For example, a housewife provides services for her family. Other nonmarket activity is done on a barter basis, for example, while a mechanic serves a motor car of an electrician who in return helps the mechanic install light fittings in the house where there has been no money paid, the activity does not add to the GDP and so does not exist for statistics.
