【摘要】This study uses property-level repeat sales transaction data to   test for the presence of a premium for single-family homes within half a mile   of stations on the METRO Blue Line in Minneapolis, Minnesota. Using a   difference-in-differences approach, we find that the premium for station   proximity varies substantially depending on control group and period   definitions for “after” light rail. Using homes in the rest of Minneapolis as   controls yields growing positive premiums from proximity to light rail stations,   while using homes in neighborhoods similar to those near stations yield   smaller premiums that fade to zero over time.
