provide them than others. If the tradable industry has high demand for a type of non-tradable good that needs more workers to be produced then the multiplier will be higher. Types of jobs created refers to the fact that certain job categories generally have higher pay than others. Higher pay results in larger amounts of disposable income that can be spent on the local economy. This results in a higher multiplier. Elasticity of local labor and housing supply refers to that the fact whenever there is an influx of new people with higher than average wages to an area, average prices will rise. This can in turn push out some residents with below average wages into lower cost areas. This results in a lower multiplier. Economists also argue that certain industries have stronger agglomeration economies than other industries, which can magnify the strength of the multiplier effect. Further, the magnitude is affected by local regional and political factors such as the unemployment levels and level of government intervention in the economy and labor market. Policy implications 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. Research United States Several scholars have found strong evidence for the presence of the local multiplier effect. Within tradable industries, Enrico Moretti discovered that, for each additional skilled job created, 2.5 jobs were also generated in the local non-tradable goods and services sectors, and an additional unskilled job created 1 job in the local non-tradable sector. Highly skilled sectors such as technology have the highest multiplier effect with five non-tradable jobs for each technology job. Moretti cites the example of Apple Computers which directly
