However, the idea was not widely used in macroeconomics until the new classical revolution of the early 1970s, popularized by Robert Lucas and T. Sergeant. These higher order solutions can be computed recursively using the rst order solution as a starting point. In the meantime, the rational expecta-tions assumption has come to be used in many fields of economics, including finance, labor economics, and industrial organization. Forecasts are unbiased, and people use all the available information and economic theories to make decisions. Under adaptive expectations, expectations of the future value of an economic variable are based on past values. A) rapidly; large B) ra.

However, the idea was not widely used in macroeconomics until the new classical revolution of the early 1970s, popularized by Robert Lucas and T. Sergeant. These higher order solutions can be computed recursively using the rst order solution as a starting point. In the meantime, the rational expecta-tions assumption has come to be used in many fields of economics, including finance, labor economics, and industrial organization. Forecasts are unbiased, and people use all the available information and economic theories to make decisions.
