The author develops a progressively refined framework composed of four typologies to help understand, explain, and analyze how various public policy levers impact new, small, and entrepreneurial businesses. Dimensions for the typologies include institutions and culture, competition and competition's intended immediate beneficiaries, impediments and supports, and policy objectives and direct/indirect action. Implications emerging from the typologies lead to potential hypotheses that can be subject to further investigation and empirical testing. This issue of JSBM carries the first of the article's two parts.
