Suppose the current yields to maturity on 3month and 6month T-Bills are 4.0 percent and 5.0 percent, respectively (yields will need to be converted to 90-day returns). In perfectly efficient markets and risk-neutral pricing, what yield should you expect to find on a 3month T-bill forward contract deliverable in 3 months? Show that for the forward yield calculated in (a) the 6month returns on a 6month spot bill and 3month spot and 3month futures bills are the same. Explain what factors would lead to a rejection of (b). ALSO, in the futures market: (1 +_sigma y_2)^2 = (1 +_sigma y_1)(1 +_1 y_1^f). where_1 y_1^f = the 3month futures yield on futures contracts due in three months
