War Memory: Evidence from Assistance during Great East Japan Earthquake

Abstract

On the basis of a natural experiment related to the Great East Japan Earthquake in 2011, the present work empirically analyzes the relationship between historical events and current attitude and determines whether regions that suffered severely during the Japanese invasion in World War II expressed small concern during the earthquake. After controlling for geographical distance, bilateral trade, and political characteristics, a negative relationship is found between the duration of invasion and number of related deaths in the invaded regions and their governments’ efforts in assisting Japan after the earthquake. Further analysis shows that political similarity to Japan helped in assisting them after the earthquake, but this effect was reduced for regions that sustained many deaths during the Japanese invasion. In addition, a mediation effect test shows that the help extended by Japan to several countries after the war through the Japanese official development assistance did not positively influence the amount of aid provided by such regions to Japan after the earthquake. These studies provide new evidence of the long-lasting influence of war. However, no robust evidence is found about the relationship between death rate and war memory. Therefore, even large countries cannot tolerate serious suffering during painful historical events.
