Query: Bad Weather, Social Network, and Internal Migration; Case of Japanese
  Sumo Wrestlers 1946-1985   Post-World War II , there was massive internal migration from rural to urban
areas in Japan. The location of Sumo stables was concentrated in Tokyo. Hence,
supply of Sumo wrestlers from rural areas to Tokyo was considered as migration.
Using a panel dataset covering forty years, specifically 1946-1985, this study
investigates how weather conditions and social networks influenced the labor
supply of Sumo wrestlers. Major findings are; (1) inclemency of the weather in
local areas increased supply of Sumo wrestlers in the period 1946-1965, (2) the
effect of the bad weather conditions is greater in the locality where large
number of Sumo wrestlers were supplied in the pre-war period, (3) neither the
occurrence of bad weather conditions nor their interactions with sumo-wrestlers
influenced the supply of Sumo wrestlers in the period 1966-1985. These findings
imply that the negative shock of bad weather conditions on agriculture in the
rural areas incentivized young individuals to be apprenticed in Sumo stables in
Tokyo. Additionally, in such situations, the social networks within Sumo
wrestler communities from the same locality are important. However, once the
share of workers in agricultural sectors became very low, this mechanism did
not work.
