The Rate of Proprietorship Among Metropolitan Areas: The Impact of the Local Economic Environment and Capital Resources
研究美国都市区自雇率受地方经济环境和资本资源的影响，发现自雇率随房屋净值、无形资产、失业率、自雇者相对收入和人口增加而上升，随州所得税率和最低工资提高而下降。
Legal rules and the economic environment play an important role in the decision to become an entrepreneur. Many studies examine the effect of such institutions at the national or state level. The metropolitan area may be a more appropriate geography to examine, since entrepreneurs often serve a more localized market and there is wide variation in both the environment for and incidence of proprietorship among metropolitan areas. We find that proprietorship increases with home equity, intangible wealth, unemployment, relative earnings of proprietors, and population. It decreases with higher state income tax rates and minimum wages.
