<p>This study examines how tuition pricing strategies affect applicant demand in differentiated higher education markets, focusing on women’s universities in Japan. While this analysis identifies correlational patterns rather than causal relationships, the findings provide important insights into pricing dynamics in specialized higher education markets. Using panel fixed-effects analysis of 55 departments across six institutions in the Tokyo metropolitan area from 2022 to 2025, we investigate the relationship between tuition levels, tuition changes, and applicant numbers. Contrary to conventional economic theory, our findings reveal a counterintuitive dual relationship: while higher tuition levels are negatively associated with applicant numbers, tuition increases show a positive association with demand. These results suggest that tuition hikes may function as strategic quality signals rather than price barriers, challenging traditional assumptions about price elasticity in higher education. The positive association between tuition increases and applications appears to reflect demand curve shifts driven by perceived improvements in institutional value, educational quality, and brand positioning. This phenomenon is particularly pronounced in niche markets where institutions successfully differentiate themselves and target less price-sensitive applicant segments. Our analysis contributes to higher education economics by distinguishing between static tuition levels and dynamic pricing changes, offering insights for enrollment management in specialized institutional contexts. Despite the correlational nature of the analysis and limited generalizability beyond women’s universities, the consistency of results across multiple robustness checks provides valuable evidence for strategic pricing decisions in differentiated markets where traditional demand theories may not fully apply.</p>
