The Effect of Introducing a New Light Beer in Norway: substitution or addition?

In this paper the question is raised if total alcohol consumption may be reduced by introducing new alcoholic beverages with low alcohol content. May such beverages substitute stronger ones, or will they be added to existing habits? It is argued that this issue deserves more attention in the future. The effects of introducing a new light beer in Norway are analysed from this perspective. The point estimates indicate a substitution, but the effect is not statistically significant.
