Increasing evidence shows that spermatogenesis is costly. As a consequence, males should optimize the use of their sperm to maximize their reproductive outputs in their lifetime. However, experimental evidence on this prediction is largely lacking. Here, we examine how a male moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) responds to the presence of rivals or additional mates and how ...

Algorithmic collusion is an emerging concept. Whether algorithmic collusion is a creditable threat remains as an argument. In this paper, we propose an algorithm which can extort its human rival to collude in a Cournot duopoly competing market. In experiments, we show that, the algorithm can successfully extort its human rival and gets higher profit in long-run, meanwhile the human rival will f...

The objective of this study is to identify experimental economic tools that can be employed to explain the role of economic behavior in overweight and obesity in the household. We identify three economic experiments that can be used to understand how parent-child economic relationships relate to obesity. Loss aversion experiments are discussed as a tool to understand challenges some individuals...

Since its emergence around mid-century, laboratory experimental economics has been widely recognized for introducing a new empirical research methodology rooted in the direct observation of human behavior. It is less well known that research in experimental economics has always gone hand in hand with its use as a pedagogical tool. A notable very early example is Harvard University professor E. ...
