摘要：1 Networks and the efficiency in
the labor market
The use of networks in the labor market is expected
to reduce the distribution cost of information on job
advertisements and job seeking in the labor market, as
well as to increase the efficiency of job advertisement
and job-seeking services. In other words, it is expected
that those who seek jobs can increase job options, and
that those who seek employees can have a diverse labor
force which meets their needs and reduce the cost of
searching and hiring. This is because a large amount of
job-related information is accumulated on a network and
information search is possible. As a result of efficient
matching between those who seek jobs and those who
seek employees, it is expected that frictional unemployment
will decrease, the period of unemployment will be
shorter, and the rate of job separation will fall.
