International Yield Curves and Currency Puzzles
发现仅用债券价格估计定价核会导致货币谜题，即模型无法解释未抛补利率平价偏离和汇率波动，通过引入影响汇率但不影响债券的定价核创新可解决这些谜题。
ABSTRACT The currency depreciation rate is often computed as the ratio of foreign to domestic pricing kernels. Using bond prices alone to estimate these kernels leads to currency puzzles: the inability of models to match violations of uncovered interest parity and the volatility of exchange rates. This happens because of the FX bond disconnect , the inability of bonds to span exchange rates. Incorporating innovations to the pricing kernel that affect exchange rates but not bonds helps resolve the puzzles. This approach also allows one to relate news about cross‐country differences between international yields to news about currency risk premiums.
