Period effects and cohort effects in life cycles : Preliminary analysis Marker, John T Jr

By: Marker, John T JrPublication details: Transportation Research Record, 2000Description: nr 1718, s. 90-6Subject(s): USA | Household | | Behaviour | Journey | Prediction | | 11Bibl.nr: VTI P8167:1718Location: Abstract: Travel behavioral data from five successive waves of the Puget Sound Transportation Panel were examined to determine whether period effects or cohort effects have a significant effect in life-cycle behavior. It was found that period and cohort effects may have a greater influence in household life-cycle models than previously believed. The results bring into question current methods using cross-sectional data analysis for life-cycle models, since predicted changes in activity behavior were not observed in households that made life-cycle transitions. The results are not conclusive, since other variables influencing activity behavior were not accounted for in the analysis.
