Temporal Analysis??

Most analysts assume the indirect and induced effects work through the economy within a year. All relationships in the model are annual (output per worker, income per worker). A direct effect of one job assumes that worker works all year. 4 workers working one quarter is one annual average jobs. To generically "quarterize" the impact results, I would: A: Report the impact employment as given by the impact reports saying that these results are for each of the 4 quarters of the year. B: Report all the other impacts (output, income) by dividing by 4 and say that the resulting calculation is the average quarterly income/output for the 4 quarters. If you know that the construction activity is "compressed" into 2 quarters only, then the average annual employment reported in IMPLAN would need to be multiplied by 2 (4qtr/2qtr) and the narrative should note that this employment only occurs over the perid of 6 months. The income/output would not change but the income/output per worker would be half the annual average as they only worked a half year. You could make these changes only to the direct effects and assume the indirect and induced still work their way through the economy over the course of a year.
