This document summarizes a research paper that examines the concept of knowledge gap as the driving force behind knowledge expansion. It defines knowledge and knowledge gap, and proposes the "pore model of knowledge gap" to explain factors hindering knowledge expansion in developing economies. Specifically, it argues that political power and lack of access to financial resources has corrupted knowledge-seeking behavior, creating a gap between low and high socioeconomic groups. To close these gaps, it recommends liberalizing education sectors to encourage more knowledge-seeking.
