To address local workforce needs and expand access to affordable bachelor's degrees, some states allow community colleges to offer bachelor's degree programs. Despite concerns that community college baccalaureate (CCB) programs will duplicate efforts and cut into the market share of nearby 4-year institutions, extant literature has yet to examine the impact of CCB adoption on bachelor's degree program enrollment and bachelor's degree production at 4-year institutions. Using program-level data, our findings show that local CCB degree programs have a negative effect on overall bachelor's degree enrollment and bachelor's degree production at 4-year institutions, but this effect is concentrated primarily within for-profit 4-year institutions. This study represents the first comprehensive evaluation of the impact of CCB degree programs on neighboring 4-year institutions.
