when economist use the term laissez-faire what economic idea are they referring to
Laissez-faire Laissez-faire (/ˌlɛseɪˈfɛər/; French: [lɛsefɛʁ] ( listen); from French: laissez faire, lit. 'let do') is an economic system in which transactions between private parties are free from government intervention such as regulation, privileges, tariffs, and subsidies. The phrase laissez-faire is part of a larger French phrase and basically translates to "let (it/them) do", but in this context usually means to "let go".[1]
Macroeconomics Macroeconomics, at least in its modern form,[26] began with the publication of John Maynard Keynes's General Theory of Employment, Interest and Money.[25][27] When the Great Depression struck, classical economists had difficulty explaining how goods could go unsold and workers could be left unemployed. In classical theory, prices and wages would drop until the market cleared, and all goods and labor were sold. Keynes offered a new theory of economics that explained why markets might not clear, which would evolve (later in the 20th century) into a group of macroeconomic schools of thought known as Keynesian economics â€“ also called Keynesianism or Keynesian theory.
