arguments for policy mechanisms to attract certain industries to a particular region often are based on analysis of local multiplier effects as justification for the associated costs of the policy. the perceived strength (or weakness) of a particular industry's local multiplier effect thereby affects what industries are most often targeted by policy makers. other proponents disagree with the logic behind trying to attract whole industries to new areas. they cite the difficulty in attracting established industries with high local multipliers (such as the technology industry). such industries are not easily engineered by government intervention as their current locations are often due to random coincidences during their founding periods. an alternative solution proposed by enrico moretti is for the government to subsidize relocation costs for workers currently in areas with high unemployment to areas with industries that provide high local multipliers.
