Our model shows that heterogeneous expectations can not only lead to speculative trading, but can also help resolve several challenges to standard representative-agent models of the yield curve. First, the relative wealth fluctuation between the two groups of agents caused by their speculative positions amplifies bond yield volatility, thus providing an explanation for the "excessive volatility puzzle" of bond yields. In addition, the fluctuation in the two groups' expectations and relative wealth also generates time-varying risk premia, which in turn can help explain the failure of the expectation hypothesis. These implications, essentially induced by trading between agents, highlight the importance of incorporating heterogeneous expectations into economic analysis of bond markets. ER -
