Markets are complete with just the short term bonds so that under the usual hypothesis of perfect foresight, the long term bond is redundant by no arbitrage in that it has no allocational implications. We dispense with perfect foresight, derive appropriate no arbitrage conditions and show that the presence of the long term bond has significant allocational implica- tions. Specifically, in the model with just the short term bond, we show that a T dimensional subset of efficient allocations can arise as Walrasian equilibria whereas the dimension of efficient allocations is one less than the number of households (as- sumed to be much larger than T). In the model with the both types of bonds, essentially all efficient allocations might arise as Walrasian equilibria; minute errors in forecasting prices might generate all income transfers that are consistent with efficiency. We argue that the beneficiaries of such unanticipated income transfers are determined not by the superiority of forecasts but rather by accident.
