Love thy neighbor? The role of trust in neighbors during the COVID-19 crisis

During a pandemic, trust can either promote cooperative behavior, as people pay attention to their actions toward other people's health, or hinder cooperative behavior by decreasing risk perception. By linking South Korea's Community Health Survey data with district-level statistics of the number of confirmed cases, I examine the effect of trust during the pre-pandemic period on district-level infection rates. I find that trust in neighbors is negatively associated with infection rates during the period when people are well aware of social distancing measures. Results of the individual-level analysis demonstrate that trust in neighbors is positively associated with the probability of implementing social distancing measures, particularly, those that are difficult to enforce. This finding implies that trust in neighbors increases people's motivation to cooperate voluntarily with public precautionary measures that can reduce the probability of infection.
