Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Hi! So I'm not at all sure about this question, but I'm still going to give it a try, hoping it and some information that I know, would be of some help to you. So the flexible accelerator model is basically an upgrade of the simple accelerator one. The most popular approach to it was defined by Koyck. The first option is ruled out because that's the simple accelerator principle. Consequently, option four is also ruled out. That leaves us with options 2 and 3. Option 3 doesn't seem right because it basically shows that there is a time lag of 2 years im determining investment. So my final answer would be option (2). But I would advise checking with a faculty or professor to be absolutely sure.
