Like most things, immigration to Russia is neither apanacea nor a poison (on the whole I would say its impact is modestly positive), but it can absolutely serve as a force that moderates the highly-touted outflow of university graduates, and the experience of Kupikupon is a very nice example of that.
Other notable speakers include Dean Karlan of Yale and President of Innovations for Poverty Action, who reflected on how the perception of microfinance has gone from being a poverty panacea to a far humbler expectation of helping the poor cope.
