sumconsumptionidot
Sumconsumptionidot is a coined macroeconomic indicator that aims to measure the speed at which aggregate consumption changes over time. In its simplest form, it represents the time derivative of total consumption expenditure in an economy, capturing the momentum of demand rather than its absolute level. If C(t) denotes the total consumption at time t, sumconsumptionidot is approximately dC/dt. In discrete data, it is commonly approximated by the difference ΔC/Δt between consecutive periods. The measure can be applied to a full aggregate or to sectoral decompositions, depending on data availability and research interest.
Calculation and data sources typically rely on national accounts data for consumption expenditure, such as household
Interpretation and uses focus on momentum rather than level. A positive sumconsumptionidot indicates rising consumption, signaling
