“…The relationship for destination state social welfare spending, on the other hand, is negative, and the relationship for origin state per capita GDP is positive, both of which run counter to theoretical expectations. However, the welfare result is less surprising given the findings of Giulietti et al (2013), Pedersen, Pytlikova, and Smith (2008), , and Massey and Espinosa (1997) that there is little evidence of immigrants being drawn more to destination states with generous social welfare benefits, and also given the likelihood that welfare spending is correlated with various omitted variables that may be driving the sign of the coefficient. The GDP result may reflect the classic "immigration hump" that many countries go through as their economies develop (Massey et al, 2002).…”
