1 The Location Decision of the Highly Educated: A Statewide Analysis Sarah Wakefield
2 Motivation New Location Theory – Less focus on business, more on people Impact on State Economies – Observe positive impacts Develop Strategies to Attract Talented Individuals – Talented: Bachelor’s degree and higher
3 My Contribution Analysis at a statewide level Inclusion of explanatory variables such as park visitors and number of libraries Analyze the effect of net migration with patent data
4 Research Questions: What factors attract talent at the state level? Does the relevance of each factor change as education level increases? Is there an observable positive impact on state economies?
5 Literature Review Kodrzycki (2001) – location decisions of the college educated – Positive net migration of recent college graduates into South Atlantic, Mountain, & Pacific regions – New England, East & West North Central, and East South Central lost the highest shares of college graduates
6 Literature Review Florida (2002) – Key role of diversity Diversity attracts better than climate, recreational, and cultural amenities – Talent and high tech industries lead to higher regional incomes
7 Literature Review Glaeser (2005) – Measure the effects of higher education on growth rates – An area with twice as many colleges in 1940 faced 4% faster growth rate after 1970 – Positive effect on wages for high and low skilled workers
8 Data – By State Dependent Variables: – Net Migration Bachelor’s – Net Migration Master’s – Net Migration Doctorate U.S. Census Bureau – Number of Patents U.S. Patent and Trademark Office 2005 – Economic Growth Bureau of Economic Analysis Independent Variables: – Per Capita Income Bureau of Economic Analysis 2000 – Violent Crime Rate Bureau of Justice Statistics 2000 – Climate U.S. Dept. of Agriculture – Number of Libraries Per Capita National Center for Education Statistics 2000 – Unemployment Rate Bureau of Labor Statistics 2000 – Restaurants National Restaurant Association 2000 – Percent Foreign Speaking U.S. Census 2000 – Park Visitors/Acreage U.S. Census 1997
9 Methodology Multiple Linear Regressions: – Dependent variable = net migration of bachelor’s degrees, master’s degrees, and doctorate degrees
10 Methodology Simple Linear Regressions: – Run regression with net migration by master and doctorate degrees
11 Overview Location choice of talent can positively impact a state Understanding which factors draw in talent can help states develop positive economic policies Regression results will indicate which factors are significant, and if talent has a positive impact on state economies

Interpretation of Results: Increase of 1 with bachelor’s degree and higher increases growth by.129% Increase of 1 with bachelor’s degree increases growth by.151% Master’s degree holders – no significant impact Increase of 1 with a doctorate increases growth by 2.79%
Conclusion Per capita income is positive and relevant in the attraction of talent at all education levels Violent crime rate – positive effect on bachelor’s degree holders – Metropolitan areas Negative effect of per capita libraries on migration of bachelor’s and doctorate holders – Educational resources not a strong priority (sample only includes ages 22-29)
Implications Preferences do vary based on education level Positive effects of net migration exist and are significant Policy Initiatives: – Restructure tax codes – Attract businesses to increase salary – Emphasize metropolitan areas – To attract doctorate holders, promote climate
