Heterogeneity: Gaube 2000<br />

In a setting with heterogeneity in prefs for PG (v h ), proves that<br />

1 Without redistributive prefs., G SB < G FB .<br />

2 With redistributive tastes, could have G SB > G FB .<br />

Intuition: if public parks benefit mostly low income households,<br />

over-provide parks to enhance redistribution<br />

First-best level of redistribution cannot be achieved using standard tax<br />

instruments.<br />

By providing park instead of welfare, redistribute income without<br />

distorting incentive to work.<br />

Example of theory of the second best (Lipsey and Lancaster 1956)<br />
