Estimating Country Risk Premiums
To estimate the long term country risk premium, I start with the country rating (from Moody's: www.moodys.com) and estimate the default spread for      
that rating (US corporates and country bonds) over the treasury bond rate. This becomes a measure of the added country risk premium for that country.  
I add this default spread to the historical risk premium for a mature equity market (estimated from US historical data) to estimate the total risk premium.  
In the short term especially, the equity country risk premium is likely to be greater than the country's default spread. You can estimate an adjusted country risk   
premium by multiplying the default spread by the relative equity market volatility for that market (Std dev in country equity market/Std dev in country bond)      
In this spreadsheet, I have used the global average of equity to bond market volatility of 1.5 to estimate the country equity risk premium.      
Enter the current risk premium for a mature equity market 4.74%
Do you want to adjust the country risk premium for the additional volatility of the equity market? Yes ! Yes or No
If no, use the country risk premium from the columns below
If yes, you can adjust the country risk premium for the relative volatility of the equity market below:
Enter the country risk premium from default spread = 5.50%
Enter the standard deviation in the equity market in the country = 61% ! Use annualized historical volatility
Enter the standard deviation in the long term bond issued by the country = 35% ! Use annualized historical volatility
The adjusted country risk premium for your country is = 9.59%
