In our recent intervention on Sri Lanka’s electricity tariffs, we offered to help the regulatory agency and the service suppliers apply the learnings of behavioral economics to the task of reducing the five percent of peak-load demand that was responsible for 17 percent of the total cost. In this oped, an author we quoted in the submission, supports pilot project proposed by the transport authority of Singapore. By providing free train rides, the LTA hopes to harness the power of free to shift demand from peak to off-peak travel. Congestion is a 10 to 20 per cent phenomenon; transport planners do not need to shift a majority of commuters to off-peak hours. As long as 10 to 20 per cent do, that is sufficient to alleviate congestion and improve the commuting experience for all.
