This study compares the predictive validity of stated purchase intentions for household durables to the probability of an eventual purchase, through the framework of a discriminant analysis. Based upon data gathered by the French National Institute of Statistics on 8,000 households and on a survey on 3,000 households, the results show that purchase intentions have a better predictive value at an individual level, and that the forecasts have a certain consistency on the whole.
