22 Background - Metro-scale Economies New firm births generated more than 6.7 million jobs in 2002, which accounted for 6.8% of total employment in U.S. metroregions.

23 Research Objectives: To test for a link between targeted venture capital investment (VCI) and localized new firm formation (NF 2 ) VCI NF 2 To identify patterned variations in NF 2 across U.S. metro-regions To elaborate the original relationship in a multivariate model ( ).

24 Literature Review - Determinants of NF 2 Extant literature reports that the regional attributes influencing NF 2 can be grouped into six (6) categories: 1) Macro-economy infrastructures 2) Market-demand conditions 3) Industry structure and dynamics 4) Infrastructure supporting innovation potential 5) Human capital 6) Unemployment rate/level

47 Research Findings Venture Capital: Current VCI levels within a region have a positive independent effect on NF 2 rates. 5-year lagged VCI flows within a region have a positive independent effect on NF 2 rates. Current internal VCI have a positive independent effect on NF 2 rates.

48 Research Findings- Cont d Regional GDP growth rate and population growth rate have positive effects on NF 2 rates. HT employment share, prior-year NF 2, current-year firm exit rate have positive effects and MSE has a negative effect on NF 2 rates. Patent portfolio size has a negative effect on NF 2 rates. Both local production of PhDs and share of population with at least a BS degree have positive effects on NF 2 rates.

49 Conclusions Variations in the firm birth rates are substantially explained by regional differences in regional output growth, population growth, industry structure and human capital as suggested by the relevant literature. There is significant empirical evidence to indicate that access to VCI is positively related to regional NF 2 rate.

50 Contributions to Literature Isolating the independent effect of VCI on NF 2 at the metro-regional level. Linking the VCI and new firm formation literatures. Extending empirical generalizations across a longer period of U.S. economic history.

51 Policy Recommendations Policies aimed to attract VCI by cutting capital gains tax, providing innovation subsidies and increasing public R&D spending can contribute to new firm creation. Policies or programs that are to support the creation of small firms, to transform large firms into small firms, to attract high-tech employment flows, or to create an easy environment for firm entry and firm exit would benefit a region s NF 2.
