Hi,
I'm trying to check that the trade processes I declared are well defined.
Is there any parameter for trade processes that functions in the same way as ACT_EFF for internal regions processes, and that has to be always included?

Regarding IRE_PRICE when using ANSWER. To define the price of a commodity produced by IMPEXP region and imported by REG1, is this correct?
            In tab Trade processes, process IMPGAS, IRE_PRICE parameter - Region is REG1; Region2 is IMPEXP and Item 5 is IMP?

Thanks!
Sara

Q1: Is there any parameter for trade processes that functions in the same way as ACT_EFF for internal regions processes, and that has to be always included?

A1: For a normal process,  ACT_EFF can be used for defining the conversion from some input flow(s) to the activity (assuming that the activity is defined by the output flow(s)). Using ACT_EFF is one way of establishing 1) the mapping between the primary inputs and outputs, and 2) the conversion  rate between them. For a trade process, there is no need to establish the mapping between the inputs and outputs, because TOP_IRE already defines that mapping. Therefore, there is no mandatory parameter similar to ACT_EFF for trade processes. The default conversion rate between the input (export) flow and the output (import) flow is 1. If you want to have some conversion rate other than 1, you can use IRE_FLO for defining the efficiency between the export and import flow (for endogenous trade), or IRE_FLOSUM  for defining the losses in the traded commodity (for both endogenous and exogenous trade).

Q2: In tab Trade processes, process IMPGAS, IRE_PRICE parameter - Region is REG1; Region2 is IMPEXP and Item 5 is IMP?

A2: Yes, that would be correct.

Thank you, Antti.
