Foreign language use is ubiquitous; however, its effect on economic behaviour remains largely unexplored. In two waves of experiments, we investigate whether using a foreign language affects selfish dishonesty in situations with asymmetric information, and test possible mechanisms. Participants perform a real effort task and are matched in pairs. Lying about one’s relative performance increases one’s own payoff at a cost to the other. As our main treatment manipulation, we vary the language of the experiment. In the first wave, in China, native Chinese speakers lie significantly more in their native language than in a foreign language (English). Social norms cannot explain this effect and have the opposite directional change. In Germany, participants lie at similar rates in their native (German) and foreign (English) languages, refuting a universal foreign language effect. In the second wave of experiments in China, we explore the relationship between language proficiency and the foreign language effect. We do not replicate the original foreign language effect. Further, language proficiency does not explain lying decisions in a foreign language. We argue that the foreign language effect is highly context dependent and could arise due to heightened group image concerns in novel situations.
