Question on calculating indirect/induced effects
Indirect effects are described as: "The impact of local industries buying goods and services from other local industries. The cycle of spending works its way backward through the supply chain until all money leaks from the local economy, either through imports or by payments to value added. The impacts are calculated by applying Direct Effects to the Type I Multipliers."
In the case of indirect employment effects, would this mean that I calculate the direct employment (which is technically provided), and then multiply that employment number by the Type I employment multiplier to get the indirect employment?
On the other hand, before I saw that description below, I was basing my calculation off of this description of the indirect employment effect:
"For Employment the Effect represents the number of jobs per $1,000,000 of business to business purchases by all resultant rounds of local Industry's purchases."
This seems to be saying to multiply the indirect multiplier by the indirect output.
Adding in the induced effect:
"For Employment the Effect represents the number of jobs supported in local Industries, per $1,000,000 of Direct spending in the target Industry, as a result of Household purchases derived from Labor Income payments throughout all rounds of the impact."
This seems to be saying to multiply the induced multiplier by the direct output. Are any of these thoughts close to the right direction?

Hello Daniel, Both these definitions are correct but apply in different contexts. This is because Effects are different from Multipliers for all indicators other than Output. This article provides a good overview of the information you are looking for: https://implan.com/index.php?option=com_content&view=article&id=121&Itemid=1706 In answer to your direct question, the appropriate value to use for estimating Indirect jobs is the Type 1 Multiplier. To determine Indirect jobs you will multiply the value of your jobs by the Indirect Multiplier and then subtract your Direct jobs from the result. So if I have 10 jobs in an Industry whose Multiplier is 1.18, I can expect to get a result 11.8 jobs, 10 of which are my Direct and 1.8 of which are my Indirect. The SAM Multipliers would work the same way, you would multiply your Direct jobs against that Multiplier to determine total jobs. Please let us know if you have any additional questions.

One final point of clarification: Did you mean induced and [b]indirect[/b] for the SAM? In other words, when I multiply the Type Sam Multiplier by the direct employment (or income) and then subtract the direct employment (income), I'm left with the sum of the indirect and induced employment (income). Do I have that right? -
Hi! Yes, if you use the Type SAM to calculate Total Employment and subtract a known Direct Employment you will end up with the Indirect and Induced Employment. In order to separate the Indirect from the Induced you would need to first calculate the Type I (Direct and Indirect) and then the SAM. I hope this helps.
