"the correlation between the art market and the economy"

Correlation is a measure of association that indicates the strength of
the relationship between two variables. Art Market is the common place
where people can distribute or purchase goods in the from of physical
material, may be a beautiful painting.

Economy is the principle market dynamice. It varies depending up on
the number of policies and steps taken by the government, authorised
group of people or natural disasters and others.

So if the economic situation degraded it will definitely affect the
Art Market.
It is very natural that Art Market grows in the Strong and medium
economic stability.

So Art Market and Economy are proportional to each other or rather
depended to each other.

Thanks for your comment, it has some weight to the the late 1980's
when the japanese wanted and paid hugh sums for the impressionist painters.
That bubble has burst and now the current state of global economies in US/UK
should see a recession in the art market, since the dot com bust this seems
to be a safe haven for investors.

I may have to rephase my question and price.
