This research applies game theory to explain how individuals in urban and rural society display hospitality toward others as a strategy. According to Sorokin and Zimmerman, rural communities are relatively small with low population density compared to urban communities. Furthermore, the social mobility of the population is comparatively less intensive in rural society; accordingly, there is a rather high possibility to encounter the same person on multiple occasions. Therefore, in rural areas where reunions are more likely, it is rational to exhibit hospitable and amicable behavior.
