What is the importance of manufacturers in the creation and dissolution of special districts?
Special district governments are independent, special purpose governmental units that exist as separate entities with substantial administrative and fiscal independence from general purpose local governments – U.S. Census Bureau
Important features
Typically single function
Territorial flexibility
Usually exempt from various laws governing general purpose governments
Year | No. of districts | Share of all govts |
---|---|---|
1972 | 23,885 | 30.5% |
1982 | 28,078 | 34.3% |
1992 | 31,555 | 37.1% |
2002 | 35,052 | 40.0% |
2012 | 38,266 | 42.5% |
2022 | 39,555 | 43.5% |
For this analysis,
The strength of manufacturers allows them to advocate for new districts and stave off the dissolution of older ones
\[ \Delta IPW_{uit} = \sum_j \frac{L_{ijt}}{L_{ujt}}\frac{\Delta M_{ucjt}}{L_{it}} \]
\[ \Delta IPW_{oit} = \sum_j \frac{L_{ijt-1}}{L_{ujt-1}}\frac{\Delta M_{ocjt}}{L_{it-1}} \]
\[ \Delta G_{it} = \gamma_{t} + \beta_{1} \Delta IPW_{uit} + \mathbf{X}'\beta_2 + \epsilon_{it} \]

As Schneider and Teske (1992) note, identifying political entrepreneurs (of which, boundary change entrepreneurs are a subset) is exceedingly difficult outside of rigorous case studies
While not perfect, looking for shocks to groups that may contain such entrepreneurs can attempt to approximate their impact
This study demonstrates that approach is viable
