Subsidy
A price support is a type of subsidy. It seems that this is not given in
the choices. However, subsidy is a form of monetary or financial support which
is provided by a local or state sector. It aims to provide economic and social
stability and development. Hence, subsidy encompasses various types of support
funded by either government or non-government offices. It can be given in form
of either direct (money, incentives and etc.) or indirect (insurance,
write-offs and etc.) in procedures.
