Description

Wooldridge Source: Thada Chaisawangwong, a former graduate student at MSU, obtained these data for a term project in applied econometrics. They come from the Material Requirement Planning Survey carried out in Thailand during 1998. Data loads lazily.

Usage

data('engin')

Format

A data.frame with 403 observations on 17 variables:

  • male: =1 if male

  • educ: highest grade completed

  • wage: monthly salary, Thai baht

  • swage: starting wage

  • exper: years on current job

  • pexper: previous experience

  • lwage: log(wage)

  • expersq: exper^2

  • highgrad: =1 if high school graduate

  • college: =1 if college graduate

  • grad: =1 if some graduate school

  • polytech: =1 if a polytech

  • highdrop: =1 if no high school degree

  • lswage: log(swage)

  • pexpersq: pexper^2

  • mleeduc: male*educ

  • mleeduc0: male*(educ - 14)

Notes

This is a nice change of pace from wage data sets for the United States. These data are for engineers in Thailand, and represents a more homogeneous group than data sets that consist of people across a variety of occupations. Plus, the starting salary is also provided in the data set, so factors affecting wage growth – and not just wage levels at a given point in time – can be studied. This is a good data set for a common term project that tests basic understanding of multiple regression and the interpretation of models with a logarithm for a dependent variable.
