Gotta catch ’em all … and sell ’em at a profit. While “Pokemon Go” is in its infancy, economists are already looking to the future — and it doesn’t look bright. Game economies, unlike the real-life variety, afford high levels of control. But many worry that the upcoming Pokemon economy, which will allow trading, will soon be divided between casual players and Pokemoguls with lots of money or time to invest. That fosters inequality that spoils the fun for new players — something game developer Niantic is eager to prevent.
