Local public goods and the demand for high-income municipalities

Affluent towns often deliver high-quality public services to their residents. I estimate the willingness to pay to live in a high-income suburb, above and beyond the demand of wealthy neighbors, by measuring changes in housing prices across city–suburban borders as the income disparity between the two municipalities changes over time. I find that a $10,000 increase in town-level median income is associated with a seven percent increase in housing values at the border. The estimated demand for high-income municipalities is primarily driven by school quality and lower property tax rates.
