MotivationLong-term phenomenon: Poverty rates are
higher in non-metropolitan than metropolitan regions (Fisher, 2007)
On Native American Indian reservations poverty rates can be triple the national average (Benson, Lies, Okunde, and Wunnava, 2011)
Recent (anecdotal) evidence identifying several instances of successful enterprises on Native American Indian reservations of the Great Plains (Clement, 2006)

QuestionsWhat are the determinants of business
startups on Native American Indian reservation areas?
How does this compare with non-Native American rural areas?
Focus: the role “Information Technology” agglomeration (IT agglomeration) plays
Focus: State of South Dakota

Why South Dakota?Home to many Native American tribes
◦Cheyenne River, Pine Ridge, Rosebud, Yankton, Lower Brule, Crow Creek, and parts of the Standing Rock and Sesseton
Boundaries (roughly) follow county lines◦According to Leichenko (2003)◦Much of the available data is county-level
Native American counties in South Dakota historically among the poorest in the nation
Yet, they have experienced substantial improvement in recent years◦Example: Shannon County (Pine Ridge Sioux)

Business Startups and Agglomeration Economies
A common reason for lackluster growth in rural economies has been that they tend to lack agglomeration economies (Gabe, 2003, 2004; Carlino, 1980)◦Lack ready access to productive capital◦Limited access to educated, skill-relevant and
experienced labor force◦Limited transportation and communication
infrastructure
![Page 10: Agglomeration Economies and Business Startups on Native American Tribal Areas Christopher S. Decker, Ph.D. Department of Economics University of Nebraska.](https://reader030.fdocuments.us/reader030/viewer/2022032702/56649cbf5503460f94985ecb/html5/thumbnails/10.jpg)
Recent Research and Agglomeration
Yet, evidence suggests some substantial growth in rural business starts
Recent research (e.g. Decker, Thompson, and Wohar, 2009; Domazlicky and Weber, 2006; Latzko, 2002) suggests that traditional measure of agglomeration (such as population density, etc.) may be playing a less critical role in regional economic development
![Page 11: Agglomeration Economies and Business Startups on Native American Tribal Areas Christopher S. Decker, Ph.D. Department of Economics University of Nebraska.](https://reader030.fdocuments.us/reader030/viewer/2022032702/56649cbf5503460f94985ecb/html5/thumbnails/11.jpg)
Perhaps a Refined Measure of Agglomeration Would be HelpfulClement (2006): examples of new Native
American businesses that exploit Computing and Information Technology (IT) to promote consumer outreach and sales growth
Suggests that local economies taking advantage of IT development◦ Inexpensive computing equipment◦ IT labor skills more prevalent, easier to acquire ◦Software written to be more generally accessible
and relevant to a broad number of industries Can lead to greater geographic dispersion of
IT-related capital and labor skills
![Page 12: Agglomeration Economies and Business Startups on Native American Tribal Areas Christopher S. Decker, Ph.D. Department of Economics University of Nebraska.](https://reader030.fdocuments.us/reader030/viewer/2022032702/56649cbf5503460f94985ecb/html5/thumbnails/12.jpg)
“IT” Agglomeration
Le Bas and Miribel (2005) constructed an IT Agglomeration measure
Identified industries which appear to rely heavily upon, or have increased their usage of IT and IT-related inputs in recent years
Found that IT Agglomeration significantly enhanced labor productivity in existing firms
![Page 13: Agglomeration Economies and Business Startups on Native American Tribal Areas Christopher S. Decker, Ph.D. Department of Economics University of Nebraska.](https://reader030.fdocuments.us/reader030/viewer/2022032702/56649cbf5503460f94985ecb/html5/thumbnails/13.jpg)
Le Bas and Miribel’s IT agglomerationBased on employment data by industryComprised of a variety of different
sectors◦ Computer & electronics, wholesale trade, information
services, financial services, professional services, educational services

Estimation Procedure
1. Following Gabe (2003) – model STARTS using models applicable to count data
◦Poisson vs. Negative Binomial◦Fixed Effects vs. Random Effects
2. OLS – dependent variable: ln(STARTS/ESTAB)
◦Not uncommon◦Intuitive appeal◦Restricts ESTAB’s effect to be unit elastic
![Page 20: Agglomeration Economies and Business Startups on Native American Tribal Areas Christopher S. Decker, Ph.D. Department of Economics University of Nebraska.](https://reader030.fdocuments.us/reader030/viewer/2022032702/56649cbf5503460f94985ecb/html5/thumbnails/20.jpg)
Estimation & SpecificationWu-Hausman test favors the Fixed Effects
model over the Random Effects modelCount models:
◦Poisson – conditional mean = conditional variance Restriction caused by the model
◦Negative Binomial (NB) – conditional mean > conditional variance
◦Applicable when data is over-dispersed Failure to account for over-dispersion can lead to
inflated standard errors
Likelihood Ratio tests favor NB

Preliminary Research ExtensionsStartups don’t necessarily translate into
regional successSurvival characteristics of rural businesses
versus metropolitan area businesses◦Agglomeration economies (as traditionally defined)
would favor metropolitan concernsSurvival characteristics of Native American
rural businesses versus non-Native American rural businesses◦Reasons for difference? Perhaps minority access to
financial capital?
