I don't know about studies but if you look beyond American borders there are countries where schools are funded at the state and/or national level rather than the local one. There is some correlation with poorer areas having worse results despite identical funding but overall the results are much more even, schools in poorer areas can even be in the top results from time to time, even beating out top tier private schools. It's not perfect, schools in "problem" areas tend to be where freshly graduated teachers go for a tour of duty before moving elsewhere, but it's still in improvement.
