Sellers are increasingly utilizing big data and sophisticated algorithms to price discriminate among customers. Indeed, we are approaching a world, where each consumer will be charged a personalized price for a personalized product or service. Is this type of price discrimination good or bad?...

This work is divided into two complementary parts. In the first part, we develop a partial equilibrium model, through which it is possible to analyze the influence of tariff modicity and the illegal occupation of poles on four agents: energy distributors, telecommunications operators, and energy...

The interchange fee applied in four-party card systems transfers incomes in the payment card business from merchants to cardholders. Assessment of the interchange fee and the interpretation of its role have prompted serious professional debate in recent years. Beyond the professional debate,...

Economic theory suggests that monopoly prices hurt consumers but benefit shareholders. But in a world where individuals or households can be both consumers and shareholders, the impact of market power on inequality depends in part on the relative distribution of consumption and corporate equity...

We examine the strategic use of Corporate Social Responsibility (CSR) in imperfectly competitive markets. The level of CSR determines the weight a firm puts on consumer surplus in its objective function before it decides upon supply. First, we consider symmetric Cournot competition and show that...
