what is the difference between pure economics and applied economics
Applied economics Léon Walras, for example, planned to organize his main work into volumes on "pure," "applied," and "social" economics. Jaffé (1983) describes Walras's plan as involving making a distinction between that which is true, is useful, and is just. In using the term true, Walras referred to propositions that necessarily followed from the nature of things. Pure economics then involves pure logic. Applied economics involves examining ways to achieve practical goals and requires the making judgments about whether or not the logic of pure economics was relevant to the real world. Social economics also presumed pure economics, but dealt with a different range of questions than did applied economics.[8]
Mixed economy Economies ranging from the United States[5][6] to Cuba[7] have been catalogued as mixed economies. The term is also used to describe the economies of countries which are referred to as welfare states, such as the Nordic countries.[8][9] Governments in mixed economies often provide environmental protection, maintenance of employment standards, a standardized welfare system, and maintenance of competition.
