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...

This paper introduces a number of game-theoretic tools to model collusive agreements among firms in vertically differentiated markets. I firstly review some classical literature on collusion between two firms producing goods of exogenous different qualities. I then extend the analysis to a...

Price discrimination requires sufficient separability of customers, sufficiently high costs of arbitrage and sufficient market power. It involves transferability of the good and/or transferability of demand. It can be categorized as first degree (or perfect), second degree (or self-selection),...

I provide a simple proof that a monopsony must necessarily be a monopoly. This is in contrast to authors who have previously asserted that either no relation exists between monopsony and monopoly, or who have relied upon additional assumptions to make an inference about monopolisitic nature of a...

Standard monopsony theory, old and new, lacks a realistic criterion to distinguish between monopsony and competitive prices. Consequently, prominent Austrian critics have by and large dismissed it. However, the idea that human action occurs in discrete steps, and consequently that the elasticity...

We introduce a theory of return-seeking firms to study the differences between this and profit-maximising models. A return-seeking objective takes into account the opportunity cost of each additional resource input to a firm's production as being a potential capital input choice in an...

I study the welfare and price implications of consumer privacy. A consumer discloses information to a multi-product seller, which learns about his preferences, sets prices, and makes product recommendations. Although the consumer benefits from accurate recommendations, the seller may use the...

Traders differ in speed and their speed differences matter. I model strategic interactions induced when high frequency traders (HFTs) have different speeds in an extended Kyle (1985) framework. HFTs are assumed to anticipate incoming orders and trade rapidly to exploit normal-speed traders'...

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...

There has been an extensive debate on measuring the sensitivity of returns of stocks. Particularly some Internal and External conditions are involved in measuring the sensitivity of returns of stocks like; industrial Production, money Supply ,Foreign exchange Rate, Interest rate, gold prices, GDP...
