Ten is a lot - I can't manage that many. But here are a few:
Convergence: rich and poor countries will continue to converge towards the global average
Inequality: poverty will not end, however, and will rise in developed economies.
Inflation: Growing population and affluence will continue to drive up prices for many basics, such as food, energy, and other commodities. This will hit the poorest the hardest and will be masked because overall inflation will not be too high, as improved manufacturing techniques keep down the price for many consumer goods.
Continental groupings: The biggest and most important economic groups will move from being nation states to being international groupings, generally based on continental geography.
