It is not efficient to sell the TV in

the second-hand market and divide the

money. A and B have to spend time and

energy (transaction cost) to sell it,

and if A really needs a TV, he or she

has to spend time and energy to buy

another one back. Furthermore, the

second-hand market is not liquid, there

is lots of searching and matching going

on. It is quite possible that A has to

pay a higher price to buy back the same

TV.

I think first-price auction is a good idea.
