Enterprise AI Analysis
Experiences, expectations, and asset prices
This analysis explores how investor expectations, shaped by personal experiences, drive asset price movements. We delve into how these subjective beliefs, particularly in the stock and bond markets, deviate from traditional rational expectations and offer new insights into valuation cycles and real interest rate dynamics.

Understanding Experience-Based Beliefs
Investor beliefs are not always aligned with 'Full-Information Rational Expectations' (FIRE). Instead, individuals process historical data by overweighting events experienced during their own lifetimes. This leads to distinct belief dynamics across age groups and generates persistent systematic deviations from FIRE.
| Feature | Full-Information Rational Expectations (FIRE) | Experience-Based Beliefs |
|---|---|---|
| Knowledge Source | Assumes investors know true DGP & parameters | Overweights data observed during own lifetime |
| Belief Dynamics | Expectations pinned by true DGP | Evolve with path of realized experienced data |
| Age-Group Heterogeneity | None (all investors know true DGP) | Predicted, mirroring survey microdata |
| Uncertainty Over Time | Decreases (as data accumulates) | Perpetually elevated (due to fading memory) |
| Impact on Stock Valuation (p/d ratio) | Reflects expected returns (e.g., risk aversion) | Can reflect cash flow growth expectations |
| Impact on Bond Market (rates) | Assumes accurate forecasting of rate paths | Forecasts can diverge from objective paths (e.g., due to hindsight bias) |

Stock Market: Valuation Cycles and Predictability
In the stock market, learning from experience about long-run cash flow growth generates valuation cycles and return predictability. Investors overweight recent experiences, leading to time-varying optimism and pessimism, which in turn influences price-dividend ratios and future returns.

Slope Coefficient of Experienced Growth on Excess Returns
This empirical finding demonstrates strong return predictability. Learning from experience about long-run cash flow growth generates valuation cycles and return predictability. Empirical evidence shows a slope coefficient of -5.50, implying stronger predictability than the model suggests.
The model predicts that when investors observe a series of high dividend growth, their estimate of future dividend growth rises, increasing the price-dividend ratio. However, because the true dividend growth is constant, these optimistic expectations eventually lead to lower objective expected returns, thus predicting future market movements.
Bond Market: Explaining Secular Real Interest Rate Dynamics
The learning-from-experience framework also provides a compelling explanation for secular movements in real interest rates, a phenomenon that has largely stumped traditional economic models.
Learning from Experience and Real Interest Rates
Problem Statement: Existing explanations for secular declines in real interest rates (e.g., changes in natural rate) are insufficient. The empirically observed decline since the 1980s is far larger than what standard models can explain.
AI Solution/Mechanism: Experience-based learning induces persistent time-variation in long-run inflation expectations. When monetary policy leans against deviations of these expectations from its target, it leads to highly persistent movements in real interest rates. This mechanism can explain why a one percentage point increase in experience-based long-term inflation expectations is associated with an increase of more than one percentage point in real rates across the term structure.
Enterprise Impact/Outcome: This model helps account for a significant portion of real interest rate variation unexplained by standard estimates, aligning with observed strong co-movement of short- and long-term bond yields and persistent forecast errors. It offers a crucial framework for predicting long-term interest rate trends.
This approach highlights how individuals' perceived inflation targets, shaped by their experiences, can deviate from central bank targets, requiring active management through real interest rate adjustments. This explains the observed co-movement of real rates with experience-based long-term inflation expectations across advanced economies.
