The theoretical analysis assumes that under a declared state of emergency, the individual going out suffers psychological costs arising from both the risk of infection and the stigma of going out. Our hypothesis states that under a declared state of emergency people refrain from going out because it entails a strong psychological cost. Then, this study estimates a model using regional mobility data and emergency declarations data to analyze self-restraint behavior under a non-legally binding emergency declaration. The results show that, compared with before the declaration of the state of emergency, going-out behavior was suppressed under the state of emergency and after it was lifted even when going out did not result in penalties, which is consistent with the theoretical analysis..

The first puzzle is “non-take-up welfare,” which occurs when needy people do not take up welfare. Second, in some countries, the benefit level is high, but the recipient ratio is low; while the other nations have lower benefit levels but higher recipient ratios. We present a model of welfare stigma in which both non-take-up and welfare fraud exist within the equilibrium. This shows the possibility for the recipient ratio to decrease as the benefit level increases in the comparative statics. Our empirical results are consistent with our theoretical results..

Specifically, we introduce heterogeneity in sensitivity to stigma among low-income and middle-income individuals, respectively, and we incorporate each player's decision to take-up benefits. In addition, we also consider the detection rate by screening for means testing welfare applicants among middle-income individuals. Our results show that a universal basic income scheme is politically supported when the detection rate is high, and means testing welfare scheme is adopted when the detection rate is low..
