Tax increment financing (TIF) and economic growth

There is clear and consistent evidence that municipalities that adopt tax increment financing, or TIF, grow more slowly after adoption than those that do not.

Regarding the effect of tax increment financing (TIF) districts on economic development, economists Richard F. Dye and David F. Merriman have studied tax increment financing extensively. Their paper The Effects of Tax Increment Financing on Economic Development bluntly states the overall impact of TIF: “We find clear and consistent evidence that municipalities that adopt TIF grow more slowly after adoption than those that do not.”

Later in the same paper the authors conclude: “These findings suggest that TIF trades off higher growth in the TIF district for lower growth elsewhere. This hypothesis is bolstered by other empirical findings.”

Summarizing, the authors write:

In summary, the empirical evidence suggests that TIF adoption has a real cost for municipal growth rates. Municipalities that elect to adopt TIF stimulate the growth of blighted areas at the expense of the larger town. We doubt that most municipal decision-makers are aware of this tradeoff or that they would willingly sacrifice significant municipal growth to create TIF districts. Our results present an opportunity to ponder the issue of whether, and how much, overall municipal growth should be sacrificed to encourage the development of blighted areas.

In their later article Tax Increment Financing: A Tool for Local Economic Development, Dye and Merriman further explain the results of their research:

TIF districts grow much faster than other areas in their host municipalities. TIF boosters or naive analysts might point to this as evidence of the success of tax increment financing, but they would be wrong. Observing high growth in an area targeted for development is unremarkable.

So TIFs are good for the favored development that receives the subsidy — not a surprising finding. It’s what elected officials, bureaucrats, and newspaper editorial writers can see and focus on. But what about the rest of the city? Continuing from the same study:

If the use of tax increment financing stimulates economic development, there should be a positive relationship between TIF adoption and overall growth in municipalities. This did not occur. If, on the other hand, TIF merely moves capital around within a municipality, there should be no relationship between TIF adoption and growth. What we find, however, is a negative relationship. Municipalities that use TIF do worse.

We find evidence that the non-TIF areas of municipalities that use TIF grow no more rapidly, and perhaps more slowly, than similar municipalities that do not use TIF. (emphasis added)

So if we are concerned about overall growth in Wichita, we need to realize that TIF simply shifts development from one place to another. The overall impact, according to uncontroverted research, is negative: less growth, not more.
