Along with the above complex human behavioural patterns in the economic arena, we have what the economist call the nudge theory. Nudges encourage the people to act in a particular way without actually changing the choices that are available to them. Thus, for instance, the behavioural economists suggest that the items that one wants to sell quickly, one has to place into the eye level shelves while others that can wait can be sent to less convenient place. It is found that nudge theory works. Maybe demonetisation in our country produced a nudge effect on all of us. It might have given us the energy to stand in long lines for hours together. The behavioural economists point out that we humans are bad losers. Wining gives us pleasure and losing gives us pain.
