I think you raise an interesting point on the second-order effects, but that is only relevant if a big country introduces basic income. In the case of Switzerland, I think the first-order effect greatly exceeds any other effect on the neighbouring countries's labor pools. Because Switzerland is freaking small (7 million people - the size of a big european city) and is surrounded by large countries (Germany, France, Italy). So let's say you get 2 millions people from each of the 3 large countries, that's 6 million people. For the large countries, this isn't such a big loss. But for Switzerland, it's almost doubling the population, which is going to be a huge problem in term of finance, housing, transports, etc...
