Frequently Asked Questions

What is a Disparity Study?

Disparity studies are a means of providing a factual basis for determining whether there are equal opportunities for all firms in public contracting and support the need, if any, for race or gender conscious, remedial procurement programs. The NCDOT study will engage in a review of NCDOT’s contracting process, availability and utilization, and analyze participation in contracts by all vendors, including Minority (“MBE”), Women (“WBE”) (collectively “M/WBE”) and Disadvantaged Business Enterprises (“DBE”) to analyze whether there is equal access to public contracts for all business owners.

This Study will cover contracts awarded between July 1, 2013 to June 30, 2018. (FY2014-FY2018) If the actual utilization of firms is less than what is expected based on firms that are ready, willing, and able to perform on City contracts (“Availability”), then a “disparity” exists. The Study will also determine whether the disparity is statistically significant enough to suggest whether any action should be taken or whether factors other than race or gender are likely to have caused the disparity.

What is the Study Process?

A disparity study process is broken out into several major parts, including statistical and econometric analysis, legal and purchasing practices analysis, anecdotal evidence analysis, and findings and recommendations. GSPC is currently collecting data from NCDOT that will be necessary to determine utilization of firms in the marketplace. Principal Investigator, Dr. Vince Eagan, will conduct policy review and interviews to understand the internal procurement processes and procedures. Our Chief Statistician, Dr. Rom Haghighi will then analyze the data to determine NCDOT’s availability and utilization of M/W/DBE firms. Senior Economist, Dr. Gregory N. Price, will then work with available data to determine, through econometric analyses and an analysis of the private sector, whether identified disparities can be attributed to the race and/or gender status of firm owners.

Anecdotal evidence is also crucial to any recommendations we may make to NCDOT as a result of our study findings. Our anecdotal evidence includes the following:

  • Survey of business owners across all work categories.
  • Firms throughout NCDOT marketplace will be contacted inviting them to complete the survey.
  • In-depth anecdotal interviews with businesses in the area, selected randomly from a list of available vendors.
  • Focus groups of randomly selected business owners to share their experiences in doing business in the state of NC and with NCDOT

Email comments, Informational meetings and public hearings which will all be open to the public.
Check the website ‘Events’ tab for times and locations of scheduled events.

Other relevant study processes include an analysis of North Carolina’s legal environment, both locally and federally and a purchasing practices analysis. The study team will conduct interviews with City procurement staff regarding their procurement process and the current contracting policies to review whether any barriers to participation exist in the contracting process.

Why should I participate?

It is GSPC’s goal to have gathered the most representative anecdotal evidence as possible from all firms currently in business or desiring to do business with NCDOT. We desire to understand both the practical challenges and barriers, as well as the positive experiences faced by businesses within the marketplace. Your participation would provide further insight into NCDOT’s practices and may shed new light on an area for improvement or substantiate those recounted by others. It is only with your assistance that we will be able to provide NCDOT with substantive recommendations that can make a real impact on their policies, moving forward.
