Chapter 12 The mathematical economics of social participation; complexity

The aim of this section is to develop a model of the linkage between the macro-dynamics of price and the micro-dynamics of individual buyers and sellers, drawing on classical micro-economic theory ( Jehle & Reny, 2001 ). Jehle and Reny's book is in three parts. The first part discusses economic agents, namely consumers and firms. The second part discusses markets, in other words what happens when the economic agents interact; and welfare, namely the social value of the outcome. The third part is on strategic behaviour, covering game theory, information economics and auctions and mechanism design. Here, the emphasis will be on the core concepts rather than on the mathematical details. In emphasising the core concepts, attention will be drawn to the fact that these core concepts have a much wider range than simply micro-economics.
