Outsourcing

There is an excellent and very interesting look into the outsourcing:

If backward time travel is also somehow possible, maybe firms in the future will choose to outsource some of their operations to the past, locating their manufacturing and other services in lower-wage time periods. This opens the possibility of transtemporal gains from trade... assuming, of course, that governments don’t implement effective trade barriers.

That's from blog Anglophilia via Marginal Revolution

So our ancestors (and may be us too) are going to fight for the work to be outsourced from our the future. We will be seeing billboards on the highways about which era is the best and cost effective for the outsourcing.

Also if we can transport goods from the past...if the earth is warmer can we export ice and rebuild the Arctic?

It would be lots of fun.
