Economic Driver Fields

This article explains Economic Driver fields in Model Reef.

You will learn:

  • What counts as an economic driver.

  • Which fields are important for economic drivers.

  • How to shape economic drivers across time.

Economic drivers are value or rate based inputs such as prices, inflation, FX rates, discount factors and index series.

1

Examples of economic drivers

Typical economic drivers include:

  • Unit prices for products or services.

  • Inflation series for wages or costs.

  • FX rate time series for currency conversion.

  • Commodity prices.

  • Index based series such as CPI-like assumptions.

These drivers are usually multiplied with operational drivers or variables.

2

Key fields for economic drivers

When editing an economic driver you will see fields such as:

  • Name A clear label, for example Price - Product A or FX - EUR to GBP.

  • Type Set to Economic driver.

  • Units For example currency per unit, percent or index.

  • Time series grid Values per period, which you can edit manually or populate via imports or presets.

  • Notes and tags To document the source and intended use of the driver.

These fields live in the Driver Editor and, in some cases, the Data Library.

Shaping economic driver series

You can shape economic drivers by:

  • Typing values directly into the time series grid.

  • Applying growth or escalation assumptions.

  • Importing historical data and extending it forward.

  • Applying seasonal multipliers where relevant.

A common pattern is to set a base rate and then apply a growth or inflation curve over time.

4

Using economic drivers in formulas

Economic drivers are often used in formulas such as:

  • Revenue = Units driver × Price driver

  • Cost = Base amount × Inflation driver

  • FX adjusted amount = Local amount × FX rate driver

They are read only in formulas and do not themselves create accounting entries until used by variables.

5

Scenario specific economic drivers

Because each scenario is its own model:

  • Economic drivers can differ between scenarios.

  • You can test different price, inflation or FX paths by editing drivers in each scenario model.

This is central for valuation and planning use cases.
