As I was buying my car, the car salesman told me he would submit my COE bid at X price for me. Since then, I have always wondered why individual buyers should not do the bidding for themselves.
When he told me X price, I wondered how he arrived at it, guaranteed some more. It was as if car dealers (or institutional bidders) knew the winning bid beforehand. To me, pure market bidding typically exhibits great price variations. But COE prices seem to cluster around the previous winning bid with an invisible floor, exhibit gradual upward-trending line (which are not supposed to appear in pure market biddings), and are uncorrelated to the prices that individual buyers would have put in if they can bid themselves.
Let us assume there are 10 buyers bidding for 3 COEs and the winning bid at the previous bidding session was $7. Assume 3 different sessions consisting of different profiles of buyers.

Let us assume there are 10 buyers bidding for 3 COEs and the winning bid at the previous bidding session was $7. Assume 3 different sessions consisting of different profiles of buyers.
- Session 1 consists of 8 medium-income and 2 high-income buyers. They submit dollar bids of 3,3,2,4,2,4,3,2,8,9. The 3 COEs are priced at the third highest bid of $4.
 - Session 2 consists of 6 high-income and 4 medium-income buyers. They submit dollar bids of 8,8,7,9,10,5,3,2,4,3. The 3 COEs are priced at the third highest bid of $8.
 - Session 3 consists of 10 car dealers. They submit dollar bids of 7,7,8,8,7,7,8,7,7,7. The 3 COEs are priced at the third highest bid of $8.
 
Because the previous session had a winning bid of $7, institutional bidders will use $7 as a reference point. To ensure their customers get their cars, they may bid slightly higher. Also, institutional bidders have no clue on their customers’ marginal propensity to spend on a COE. Over time, a trend line forms. Whereas in Session 1 and 2, individual buyers submit bids based on what they can afford. Sessions that consist of more rich people will lead to higher bids, and sessions that consist of less well-off people will naturally lead to lower bids. I think the latter scenario tends to dominate the former. This is behavioural economics. Institutional vs individual bidding leads to different price outcomes.
When I asked several AI platforms, all of them concluded that individual bidding would almost certainly result in lower and fairer COE prices. The implementation challenges around financing coordination and market knowledge gaps are technically solvable through enhanced digital platforms and modified lending practices. Ask AI yourself.
I am not an expert in COE dynamics. I am just wondering how COE prices will be if we can bid ourselves. If I could, I would not have bid at the price that my car salesman did.
						
					
   the real buyers go in knowing how much to pay in all for a car - can accept take else drop.   I have never heard of buyers complaining about how high the COE bid is… rather when will the car be delivered.
