Abstract: This thesis discusses competition and coordination in the market. On the supply side, firms decide optimal competing strategies in pricing while considering corporate social responsibility. On the demand side, on one hand, consumers can act selfishly without considering social norms. On the other hand, consumers can coordinate so that better outcomes can be achieved: for example, a reduction in market inefficiency or an improvement in welfare. I analyze the relationship between the demand and supply sides, and study how the preference and behaviour of one side can affect the other. I then discuss the incentives of both firms and consumers, either competitive, non-cooperative or coordinative. This thesis consists of four articles. The first article points out a new cause of market inefficiency in competitive markets. I propose a coordinative solution to the problem. I show that the market clears if consumers coordinate in a certain way and, therefore, confirm the value of coordination in competitive markets. The second article studies the role of socially responsible actions in a lobbying game. Firms' investment in corporate social responsibility, for example, on environmental protection or animal rights, is proved to be a strategic action that effectively reduces lobbying costs and improves welfare. The other two articles study boycotts. I examine how consumers' behaviour that is driven by environmental concerns can jointly cause a change in firms' behaviour towards more socially responsible actions, and how firms choose their best reactions to deal with boycotts.N/A
