SBA guaranteed lending and local economic growth

"Increasingly, policymakers look to the small business sector as a potential engine of economic growth. Policies to promote small businesses include tax relief, direct subsidies, and indirect subsidies through government lending programs. Encouraging lending to small business is the primary policy objective of the Small Business Administration's (SBA) loan-guarantee program. Using a panel data set of SBA guaranteed loans, we assess whether SBA guaranteed lending has an observable impact on local economic performance. We find a positive and significant (although economically small) relationship between the relative levels of SBA guaranteed lending in a local market and the future per capita income growth in that market"--Federal Reserve Bank of Atlanta web site.
