Heterogeneous Effects on Private Education Spending in Latent Groups in Korea

Abstract

This study examines people's response to well‐known determinants in private education spending (PES). Based on the Korean Education Longitudinal Study, we divided the private education decision‐making process into two parts: whether to spend and how much to spend. Due to omitted environmental factors, latent subgroups that share the same PES effects were classified using a clustering methodology. Empirical analysis found that people respond differently only to household income and school year. For 40% of the observations, household income has a significant impact on PES decisions. There is no effect of household income in the other subgroups, whereas different patterns of PES according to the school year induce heterogeneity in other subgroups. There is no heterogeneity for the effects of gender, educational environment and plans to attend college.

Agile teaching methodology - Manual 

“…This method can be effective for mastering highly structured skill-building tasks because learners share a similar level of knowledge. This approach may also be well-suited for language learning or the acquisition of specific content that requires reinforcement of similar knowledge or skills (Cooper et al, 1990;Johnson and Johnson, 1984;Lee and Ihm, 2022). Additionally, students typically pre-fer collaborating with peers who share similar characteristics, leading to increased satisfaction with learning ac-tivities conducted in homogeneous groups.…”
