Illustrate graphically what would happen in the short run and in the long run to the price level and Real GDP if individuals hold rational expectations, prices and wages are flexible, and individuals overestimate the rise in aggregate demand (bias upward).
If most people have rational expectations, how long will recession last ? Explain.
Which of the following best describes the concept of 'rational expectations' in the context of macroeconomic theory?a) The hypothesis that consumers and firms expect future inflation to match past inflation rates without considering current economic policies.b) The idea that individuals and firms make forecasts of future economic variables based solely on historical data, ignoring all current available information.c) The theory that individuals and firms use all available information, including current and historical data, to make accurate predictions about future economic variables.d) The assumption that individuals and firms consistently underestimate the impact of monetary and fiscal policies on the economy due to a lack of available information.Please don't use ai please provide valuable answer otherwise be ready for disupvote
