Classified broadly, two motives for intra-family transfers exist: altruism and selfishness. This paper examines two selfish hypotheses − the exchange motive (strategic bequest motive) and the demonstration effect − using a new Japanese micro data set. My analysis of the determinants of intergenerational co-residence, distance between residences, and frequency of contact yields considerable supp...

The aim was to better understand the role of motives in exercise participation. It was hypothesised that motives influence exercise participation by influencing behavioural regulation, and that motives are themselves influenced by personality traits. Data were from a cross-sectional questionnaire survey of 252 office workers, mean age 40 years. Analysis was by structural equation modelling. Acc...

This paper examines how aversion to risk and aversion to intertemporal substitution determine the strength of the precautionary saving motive in a two-period model with Selden/Kreps-Porteus preferences. For small risks, we derive a measure of the strength of the precautionary saving motive which generalizes the concept of "prudence" introduced by Kimball (1990b). For large risks, we show that d...
