Unfortunately, the data required for a convincing implementation of their idea have been either virtually nonexistent (for financial wealth) or of questionable quality (for consumption). Our main contributions ...

According to existing theory, the introduction of a private label has an ambiguous effect on the prices of competing national brands. We undertake an empirical analysis of the effects of private label entry on national brand prices in the Norwegian food sector. We first estimate a set of 83 dynamic price regressions. The results suggest that introduction of a private label typically leads to hi...
