The speculation, then, is equivocal. Quality and price mayor will not be positively correlated, depending on the volume of information available to individuals. The empirical success are Similarly mixed. A number of experiments have discovered a positive correlation amongst the two variables.40 These reports, even so, were based mostly totally on experimental evidence instead of on marketplace info. When current market data ended up utilised, the effects differed by product class. Nondurables usually exhibited a weak or negative correlation between cost and quality (with quality measured by Customer Report rankings, which typically give attention to product overall performance), when durables confirmed a significant positive correlation.
