Re: trade flows data between regions connected th MRIO
-
1) Sorry, no - they are calculated iteratively through the trade flow data and the single region I-O's for each of the regions. 2) To calculate the exports to the rest of the world, combine the two regions into a single model and look at the domestic + foreign imports and exports. Unlike Version two where the econometrics calculated different values for different situations, version three's trade flows are consistent combining regions or aggregating sectors. -
If you mean the trade flows that form the basis of the transactions, see this thread: http://implan.com/v4/index.php?option=com_kunena&func=view&catid=80&id=7615&Itemid=35#7622 -
I just built an impact model that connects two regions through an MRIO. What I would like to do is now export the trade flows and multipliers for the two areas to see how the regions impact one another. You mention in a previous post the "ImpactCommodityImportBase" in the access database; how do I access this? -
1.When shocking an MRIO using ''household income change'', the total impacts in both regions is only reflected as ''induced effect''. The direct and indirect impacts in both regions are 0. Is this because household income spending affects induced impact only or? 2. What is the difference between the values in the ''value added' section and 'output' in the 'top ten industries affected by a shock'' sorted by total value added? Thank you -
1. Theoretically spending by households/labor income is an induced effect that resulted from some industry activity. If you wish to have household spending as direct/indirect and induced, you would need to import household spending as an institution spending pattern (under Activity Options>Import). These imported institution spending patterns are not run through the SAM so you would have to remove taxes and saving externally to IMPLAN before setting the activity level - that is, the entire activity level will be run through the multipliers as disposable income. 2. Total Output = Value Added plus Intermediate Outlay. They are highly correlated so they may not sort any differently, but occasionally they will. -
Not directly through the software. If you are trying to do impact analysis, you can combine the study area data for the categories in and re-import into the software as an impact vector. ( see http://implan.com/V4/index.php?option=com_content&view=article&id=573:573&catid=237:KB20 ) Or more simply, divide the direct effect (activity level) between the 2 categories. -
we are currently working the impact of direct payment programs made in region A on region A and the ripple effect on region b. Do you think that we should shock the MRIO with the gross payments or net payments i.e gross payment minus taxes, social security and medicare? Does the production function in IMPLAN automatically calculate the deductions(social security, medicare payments)? Thank you for your help -
Depends on how you enter it. If you enter as Employee Compensation (Activity Type: Labor Income) the software will remove social insurance for you before passing money to local households. If you enter as Household (Activity Type: Household Income Change) the software will remove income taxes and savings (and not social insurance). If you use Activity Options>Import>Institution Spending Patterns and choose a household, you will need to remove all taxes and savings yourself as each dollar will be treated as disposable income (all will be spent to buy goods and services). -
Version 2 used econometrics based on a 51 state for 125 commodities MRIO - an MRIO initially created by Karen Pohlenski using a gravity model in 1977. For details see this paper: http://implan.com/V4/index.php?option=com_docman&task=doc_download&gid=186&Itemid=7 Version 3 uses a doubly constrained gravity model to create all trade flows for 3142 counties for 430 commodities. The observed values from this model are used as the trade flows in version 3. For details see this paper: http://implan.com/V4/index.php?option=com_docman&task=doc_download&gid=138&Itemid=7 Note: we are in the process of creating a new set of econometric equation based on the current trade flows. We hope to be able to apply the new equations for zip code models and for specific commodities whose supplies are changed by user edits of the study area data. -
hi again, I wanted to show my friends a demo video that you posed on your website that demonstrates the use of MRIOs on version 3. I tried to see it again yesterday but I couldnt find it online. Is it possible that you might be able to email it to me on eyosiyas.tegegne@okstate.edu or choyeyeye@gmail.com? Thanks -
