The comparative part will compare the above issues across Britain, France and the US. In this way, it can be ascertained how much of the consumption patterns are determined by local conditions and how much was part of a general trend. . It will be assessed how country differences can be explained; for example, whether differences in income elasticity’s can explain differences in diffusion patterns. Further, a model with quantity elasticities and relative prices will be developed and used to disaggregate paired differences in consumption patterns into the effect of ‘technology’ and the effect of ‘tastes’. .
