Question: Suppose 0=(0,..., 6,)' is unknown, and a = (a,,..., a,)' has utility g(0- a, Y), where all second partial derivatives of g exist and Y

Suppose 0=(0,..., 6,)' is unknown, and a = (a,,..., a,)' has utility g(0-

a, Y), where all second partial derivatives of g exist and Y is an unknown random variable. For a close to 0, heuristically show that the implied loss for decision making can be considered to be a shifted quadratic loss of the form L(0,

a) (0-a+c)'Q(0-a+c).
