Evolutionary Game Theory and Behavioral Economics
I. Introduction
With the increasing importance of mathematics in economics approaches, our project is to focus on the application of quantitative science to behavioral economics. Specifically, we will investigate the more sophisticated tools needed to develop more complicated economic models as the economic thoughts evolve. The economic paradigms of interest are the Walrasian paradigm, which dominated in the third quarter of the 20th century, and another economic paradigm which we refer to as “Bowles’ paradigm” for the sake of easy distinction (it does not necessarily mean that Samuel Bowles invented this paradigm).
We will first analyze Walrasian’s paradigm and the mathematics behind it. Then, we will point out some of its shortage, i.e. things that the model cannot explain. Finally, we will use the game theoretical approach of Bowles’s paradigm to explain those.
II. Necessary Backgrounds
a. Classical Game Theory
b. Evolutionary Game Theory
c. Others
"""III. Walrasian paradigm"""
assumes that individuals choose actions based on the far-sighted evaluation of their consequences based on preferences that are self-regarding and exogenously determined
social interactions take the exclusive form of contractual exchanges
that increasing returns to scale can be ignored in most applications and institutions do not evolve
institutions exist to facilitate trade
represents economic behavior as the solution to a constrained optimization problem faced by a fully informed individual in a virtually institution-free environment
Deduced a few strong predictions concerning the outcomes likely to be observed in the economy
IV. Theoretical Institutional Economics (Bowles’ paradigm)
Bowles’ paradigm assumes non-contractual social interactions, adaptive and other-regarding behaviors, and generalized increasing returns.
