Cost Function of Electricity Producers (1955, Nerlove Data)

Description

Cost function data for 145 (+14) US electricity producers in 1955.

Usage

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: fuel price.
fuelshare: cost share for fuel.

Details

The data contains several extra observations that are aggregates of commonly owned firms. Only the first 145 observations should be used for analysis.

Electricity <- Electricity1955[1:145,]

## 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)

## hypothesis of constant returns to scale
linearHypothesis(fm_all, "log(output) = 1")

## log quadratic cost function
fm_all2 <- lm(log(cost/fuel) ~ log(output) + I(log(output)^2) + log(labor/fuel) + log(capital/fuel),
  data = Electricity)
