Longitudinal analysis of exchanges of support between parents and children in the UK

We consider how exchanges of support between parents and adult children vary by demographic and socio-economic characteristics and examine evidence for reciprocity in transfers and substitution between practical and financial support. Using data from the UK Household Longitudinal Study 2011–19, repeated measures of help given and received are analysed jointly using multivariate random effects probit models. Exchanges are considered from both a child and parent perspective. In the latter case, we propose a novel approach to account for the correlation between mother and father reports and develop an efficient Markov chain Monte Carlo algorithm suitable for large datasets with multiple outcomes
