Answer: An increase in dilution effects from the privatization of large state-owned enterprises

## Explanation According to the Grinold–Kroner model, the most likely reason for high economic growth but low real return on equity is **an increase in dilution effects from the privatization of large state-owned enterprises**. The Grinold–Kroner model decomposes equity returns into: - Income return (dividend yield) - Nominal earnings growth - Repricing return (P/E multiple expansion/contraction) - Share dilution/repurchase effects When large state-owned enterprises are privatized, they typically issue significant amounts of new shares to the public. This creates substantial dilution effects that can depress equity returns even when the underlying economy is growing strongly. The dilution from massive privatization programs can offset the benefits of economic growth in terms of equity returns. Option A (P/E repricing) would typically affect returns in the short term, while Option C (decreased dynamism) would likely reduce both economic growth and equity returns. **Correct Answer: B**
