Rational expectations ensure that decision-makers read the corrected signals correctly. Monetarists instead support the generalized assertion that the correct approach to unemployment is through microeconomic measures (to lower the NAIRU whatever its exact level), rather than macroeconomic activity based on an estimate of the NAIRU in relation to the actual level of unemployment. Save for … Keynes affirms that consumption and investment can be affected by expectations, and adds that part of the expectations of prospective yields are based upon existing facts, assumed as certain, and partly future events, which cannot be forecasted with full confidence (Keynes, 2008).
