Episode Notes: The Term Premium Puzzle and its Macroeconomic Implications
- Introduction:
- Topic: The term premium puzzle and its relevance in macroeconomics and central banking.
- Definition: Observation that long-term bond yields are higher than short-term ones, even after inflation adjustments.
- Why It's a Puzzle:
- Standard Economic Theory: Investors should need compensation for added risks in long-term bonds.
- Empirical Evidence: Term premium (difference between long-term bond yield and expected future short-term interest rates) is positive and sizable.
- Significance for Policy Makers: High or low term premium has implications for economic growth and financial stability.
- Chien and Lee's Contribution:
- Proposed Model: General equilibrium model that integrates heterogeneous portfolios across households and a mean-reverting aggregate consumption process.
- Key Explanations:
- Slow mean-reverting consumption growth.
- Segmented asset-market mechanism.
- Household Behavior: Households in the model have varied preferences and hold diverse portfolios, which can generate a positive term premium even without aggregate risk.
- Model Predictions: Predicts a high real term premium of 1.92% for 30-year zero-coupon bonds, matching empirical evidence.
- Relevance to Asset Pricing Literature: Model generates high/volatile equity premium with stable risk-free return, aligning with asset-pricing studies.
- Key Takeaways:
- Understanding the Term Premium: Essential for informed policy decisions about interest rates and financial regulations.
- Chien and Lee's Model: Provides an intuitive explanation reconciling the gap between asset prices and aggregate macroeconomic variables.
- Implications for Future Studies: The model sets a foundation for more comprehensive studies and offers policy insights for addressing term premia concerns.
