Answer:
All of the above.
Step-by-step explanation:
Activism is used in both politically and also in academic research. Its usage academically means only the willingness of a judge to strike down the action of a certain branch of government or to overturn a judicial precedent, with no implied judgment as to whether the activist decision is correct or not.
Therefore in the scenario above, activism totally believes that it takes a very long time to reach the long run. Their research also welcomes that frictions to the self-correcting mechanism of markets prevent prices and wages from being very flexible. And aslo that Keynes was right with his statement "in the long-run, we are all dead".
