Optimal Search in the Public Goods Games with Multiple Periods

 

 

 

Abstract

According to experimental evidence from the literature, in public goods games, we know people will gradually decrease their contribution to zero until the final round of the period. However, when we restart the period, we find people may increase their contribution again in some initial rounds. We call this phenomenon the restarted effect. In this paper, we want to use the optimal search to explain the restarted effect without violating the rational assumption of people. Therefore, we will test whether people use optimal search rules in public goods games with multiple periods in different treatments. We will also give another definition of types for people based on their contribution strategy, view how types change between the periods, and find the solution to increase cooperation in the public goods game based on people's types.
