The gross world product (GWP) is the combined gross national income of all the countries in the world.
When will the 10-year average Gross World Product annual growth rate first exceed 10%?
This question resolves as January 1st of the first year T, such that:
Moreover, GWP at T must exceed 260% of the maximum over all years >= 10 years prior.
Each year's GWP is to be given in constant prices (adjusted for inflation), in USD.
World Bank data should be used to resolve this question. If that's unavailable, other authoritative source of economic data may be used.
