DP16381 The real channel for nominal bond-stock puzzles

We present evidence that the mix of transitory and permanent shocks to consumption is changing over time. We identify three regimes: two highly persistent regimes where either permanent or transitory shocks are relatively more dominant, and a disaster regime that is largely transitory. We study implications of this finding for asset prices. The transition from the second to the first regime in the mid-1990s makes the correlation between equities and bonds switch sign from positive to negative as in the data. The real bond and equity yield curves are approximately flat. The nominal bond curve is upward sloping. These results are achieved without relying on the nominal channel too much. That is, as in the data, the variation of inflation in the model is under 40% as a fraction of variation in nominal yields.
