Economy
An economy (from Greek οίκος – "household" and νέμoμαι – "manage") is an area of the production, distribution, or trade, and consumption of goods and services by different agents. Understood in its broadest sense, 'The economy is defined as a social domain that emphasizes the practices, discourses, and material expressions associated with the production, use, and management of resources'. Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two parties agree to the value or price of the transacted good or service, commonly expressed in a certain currency. However, monetary transactions only account for a small part of the economic domain.
Market
The market, over time, is its own worst enemy. Indeed, the valiant and ultimately successful efforts of New Dealers to set American capitalism back on its feet were most vigorously opposed by many of their eventual beneficiaries. But although market failure may be catastrophic, market success is just as politically dangerous. The task of the state is not just to pick up the pieces when an under-regulated economy bursts. It is also to contain the effects of immoderate gains. After all, many Western industrial countries were doing extraordinarily well in the era of Edwardian social reform: in the aggregate, they were growing fast and wealth was multiplying. But the proceeds were ill-distributed and it was this more than anything which led to calls for reform and regulation.
