SCEPA and INET are proud to present an online economics class - advanced microeconomics - taught by Duncan Foley, the Leo Model Professor of Economics at The New School. The series includes videos of 14 class lectures, including Professor Foley's presentations and discussions with students.
Class 06: Social Interaction (Part C)
At the beginning of the sixth lecture, the canonical social interaction model and studies are reviewed and different cases are visualized graphically in order to precisely define the meaning of the strategic contementarity and the strategic substatibility in the model. In the former strategic, the more the people that follow the same action the better the result, whereas in the latter, the more the people that follow an action, the less the chances are that one would wish to follow the same strategy. Additionally, an accurate description is given based on the quantal decision response. The Hawk and Dove cases are also presented as an algebraical example of how a biological chain of these two species tends to be in harmony and why none of the two species has an evolutionary advantage over the other. In the end, the audience is presented with examples of a strong strategic contementarity, in which the path dependence determinates to a great extend the winners.
