##### Partly Artificial Data on the U.S. Economy

These are partly contrived data from Kmenta (1986), constructed to illustrate estimation of a simultaneous-equation econometric model. The data are an annual time-series for the U.S. economy from 1922 to 1941. The values of the exogenous variables D, and F, and A are real, while those of the endogenous variables Q and P are simulated according to the linear simultaneous equation model fit in the examples.

##### Usage

`data("Kmenta", package = "ivreg")`

##### Format

A data frame with 20 rows and 5 columns.

- Q
food consumption per capita.

- P

- D
disposible income in constant dollars.

- F
ratio of preceding year's prices received by farmers to general consumer prices.

- A
time in years.

```
# NOT RUN {
data("Kmenta", package = "ivreg")
deq <- ivreg(Q ~ P + D | D + F + A, data = Kmenta) # demand equation
seq <- ivreg(Q ~ P + F + A | D + F + A, data = Kmenta) # supply equation
summary(deq, tests = TRUE)
summary(seq, tests = TRUE)
# }
