data("Electricity1955")

Format

A data frame containing 159 observations on 8 variables.

cost

total cost.

output

total output.

labor

wage rate.

laborshare

cost share for labor.

capital

capital price index.

capitalshare

cost share for capital.

fuel

## Example 7.3
## Cobb-Douglas cost function
fm_all <- lm(log(cost/fuel) ~ log(output) + log(labor/fuel) + log(capital/fuel),
  data = Electricity)
summary(fm_all)
