International migration represents a potential channel for the transmission of norms, attitudes, and values back to the home countries. In this paper, we explore how international migration affects tax morale and aversion to the free-riding of members of the household left behind in the home country. We use a rich longitudinal household-level database on Polish society (period 2007–2015) that allows us to observe social attitudes and values of individuals before and after the actual migration of a member of the household. We find that having a migrant in the household has a significant and positive effect on tax morale and increases aversion toward free-riding of stayers. We also find that migrants have a lower level of tax morale before departure compared to stayers, suggesting that international migration leads to an overall gain in pro-social behaviors.

A high number of migrants returned from their transatlantic sojourn to their native Hungary between the 1880s and the 1930s. Despite being pauperised and marginalised in the United States, they encountered norms and mechanisms of a democratic society and cultural patterns unknown to the rural society they hailed from. Upon returning, they implemented some of these practices. The paper investigates the durability of this cultural change and argues that the transatlantic transmission of norms was outweighed in significance by internal, regional movements.
