Direct ValueDirect Value

Represents the value of production Represents the value of production captured by output quantity and captured by output quantity and output prices.output prices.

Secondary effects are the values Secondary effects are the values from the economic activity, spending from the economic activity, spending and re-spending stimulated by the and re-spending stimulated by the direct effect (multiplier effects). direct effect (multiplier effects).

To convert total production to direct value of To convert total production to direct value of production need to determine output prices.production need to determine output prices.

For each category and quality of output will For each category and quality of output will have a specific output price. The more have a specific output price. The more detailed the price data the more accurate detailed the price data the more accurate the value estimate.the value estimate.

There will also be regional variation in prices There will also be regional variation in prices with distribution of transportation costs.with distribution of transportation costs.

ValueValue

In the absence of appropriate data may need In the absence of appropriate data may need to use average prices.to use average prices.

Important to apply the appropriate price data Important to apply the appropriate price data for the year of production to capture the for the year of production to capture the interdependence of production quantity and interdependence of production quantity and price.price.

Therefore, will require a time series of output Therefore, will require a time series of output prices corresponding to the time series of prices corresponding to the time series of production levels.production levels.
