Description

Panel data on 14 paddy farmers from Aurepalle, India, collected over ten years (1975-76 to 1984-85). Includes farmer characteristics (age, schooling) and production variables (output, land, labor, bullocks, input costs).

Usage

data("Indian")

Format

A data frame with 273 observations (an unbalanced panel of 34 farmers over 10 years) on the following 10 variables.

id

a numeric vector containing a unique identifier for each farmer

yr

a numeric vector containing the year of the observation

age

a numeric vector containing the age of the primary decision maker

school

a numeric vector containing the number of years of schooling of the primary decision maker

yvar

a numeric vector containing the natural logarithm of the total value of output (rupees)

Lland

a numeric vector containing the natural logarithm of the total area of land operated (ha)

PIland

a numeric vector containing the proportion of land that is irrigated

Llabor

a numeric vector containing the natural logarithm of the total number of hours of hired and family labour used

Lbull
