Abstract
Given the outbreak of Covid-19 most countries have adopted prevention policies that restrict economic and social activities to curb the spread. This has led to increased vigilantism and violence; for instance, Japan reported many cases of stores and firms experiencing harassment for breaching the restrictions during the state of emergency. Accordingly, this study empirically investigates the hostility toward the violation of restriction policy (breaching behavior) by stores in Japan and provides policy suggestions for efficient strategies to reduce the hostility level. We conducted an online randomized experiment of 1,600 individuals in Japan and measured their level of hostility by implementing joy-of-destruction minigames.

Experimental Design

Experimental Design
The Joy-of-Destruction (JoD) minigame analytically measures antisocial or conflict behavior by estimating a willingness to harm others at an own cost. In this experiment, the participants are initially endowed with 100 Japanese yen, besides the participation allowance of 35 yen. Prior to the JoD experiment, the participants are informed that the research team will donate 500 yen per participant to an anonymous store that is negatively affected by the COVID-19 pandemic. The participants must decide whether to reduce (“burn”) the donation amount by 100 yen at a personal cost of 20 yen. Thus, participants can spend all their endowment amount, reducing it to zero. They can also choose to keep 100 yen by choosing not to reduce the donation. The study only considers money-burning expenses from 20 yen to 100 yen by 20 yen intervals (i.e., the money-burning choices are 0, 20, 40, 60, 80, and 100 yen).
