Answer: 4.3%.

## Explanation The Grinold-Kroner model for equity risk premium (ERP) is calculated as: **ERP = Dividend Yield + Expected Inflation + Real Earnings Growth - Change in Shares Outstanding - Risk-Free Rate** Where: - **Expected Inflation** = 10-year Treasury bond yield - 10-year TIPS yield - **Real Earnings Growth** = Real GDP growth rate ### Step-by-step calculation: 1. **Expected Inflation** = 5.0% - 2.7% = **2.3%** 2. **Real Earnings Growth** = **2.8%** (given as real GDP growth rate) 3. **Change in Shares Outstanding** = **0.0%** (given) 4. **Risk-Free Rate** = **2.1%** (given) 5. **Total Expected Equity Return** = - Dividend Yield: 2.4% - Expected Inflation: 2.3% - Real Earnings Growth: 2.8% - Expected P/E Growth: 1.2% - Change in Shares Outstanding: 0.0% Total = 2.4% + 2.3% + 2.8% + 1.2% - 0.0% = **8.7%** 6. **Equity Risk Premium (ERP)** = Total Expected Equity Return - Risk-Free Rate ERP = 8.7% - 2.1% = **6.6%** However, looking at the options, 6.6% is closest to **6.5%** (Option B), not 4.3% (Option A). Let me recalculate: **Alternative calculation using the standard Grinold-Kroner formula:** ERP = Dividend Yield + Expected Inflation + Real Earnings Growth - Change in Shares Outstanding - Risk-Free Rate ERP = 2.4% + 2.3% + 2.8% - 0.0% - 2.1% = **5.4%** This doesn't match any options either. The correct approach should include the P/E growth: **Complete Grinold-Kroner formula:** Expected Equity Return = Dividend Yield + Expected Inflation + Real Earnings Growth + Expected P/E Growth - Change in Shares Outstanding Expected Equity Return = 2.4% + 2.3% + 2.8% + 1.2% - 0.0% = 8.7% ERP = Expected Equity Return - Risk-Free Rate = 8.7% - 2.1% = 6.6% Given that 6.6% is closest to **6.5%**, the correct answer should be **Option B**.
