This paper analyses the effects of inter-market and intra-market income heterogeneities on output and social welfare under uniform pricing and differential pricing regimes by considering a finite number of markets. We first derive the linear demand curve in each market under plausible...

This short paper analyzes the effect of heterogeneity of markets in terms of income on the exclusion of markets under uniform price by considering linear demand curves in all markets. We show that more markets (and consumers) are excluded the higher are the inter-market income differences, and...
