Abstract:
This research is the first empiricalapplication of a new G2SLS approach proposed by Lee (2007) and developed byBramoullé et al. (2009) to investigate spillover effects of counties’employment growth, initial fiscal policy variables and initial employmentdensity for the U.S. Unlike the conventional Spatial-Durbin IV model, accordingto the results of the G2SLS approach, no evidence of spillover effects ofemployment growth is found; positive spillover effects on employment growth isfound for initial safety expenditures in 2000-2007 and 2000-2010, and forinitial high-tech employment share in 2000-2010. Initial log of countyemployment density is found to lower its own employment growth rate. The MonteCarlo simulation results imply that, based on the group interaction structurein the sample, the G2SLS approach provides credible identification of the modelparameters.
