Another Perspective In focused harmony, to have positive interest, P=E[3/2x | x<=p]. Bunch one might want to offer just if x<=p. Bunch one is willing to purchase a positive sum if the value paid equivalents the normal utility addition molding on gathering one might want to offer.

Slide 13

If Information is Symmetric Both gatherings have the same valuation of the autos.

Slide 14

If Information is Symmetric D=(Y1+Y2)/p S=N=Y2 S=N=2/3Y2 D=Y2/p 0 1 3/2 p

Slide 15

If Information is Symmetric Note there is a greatest utility increase of N/2 if the harmony is aggressive (situation (3)). With uneven data, no exchange happens, U1+U2=Y1+Y2. With symmetric data and focused harmony (p=1), U1+U2=Y1+Y2+N/2.
