A market where all or part of a change in demand is not reflected in a corresponding change in supply, but instead in a change in consumption elsewhere.
Constrained market datasets include a conditional exchange with a direct activity link to the consumption activity that is affected by the change in demand. This exchange is activated only for specific system models that take into account market constraints, e.g. the consequential system model.
When the system model "allocation, ecoinvent default" is chosen, the conditional exchange is not activated and the constrained markets behave like any other markets.
To understand how this market behaves during consequential linking, please see the Data Quality Guideline.
