macroS2010 Lec23-page 5 http://www.arts.cornell.edu/econ/wissink/econ102jpw/ Time Lags Regarding Monetary & Fiscal Policy The recognition lag refers to the time it takes for policy makers to recognize the existence of a boom or a slump. The implementation lag is the time it takes to put the desired policy into effect once economists and policy makers recognize that the economy is in a boom or a slump. The implementation lag for monetary policy is generally much shorter than for fiscal policy. The response lag is the time it takes for the economy to adjust to the new conditions after a new policy is implemented; the lag that occurs because of the operation of the economy itself. E.g., The delay in the multiplier of government spending occurs because neither individuals nor firms revise their spending plans instantaneously.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
