Description

Wooldridge Source: J. Mullahy (1997), “Instrumental-Variable Estimation of Count Data Models: Applications to Models of Cigarette Smoking Behavior,” Review of Economics and Statistics 79, 596-593. Professor Mullahy kindly provided the data. Data loads lazily.

Usage

data('smoke')

Format

A data.frame with 807 observations on 10 variables:

• educ: years of schooling

• cigpric: state cig. price, cents/pack

• white: =1 if white

• age: in years

• income: annual income, $

• cigs: cigs. smoked per day

• restaurn: =1 if rest. smk. restrictions

• lincome: log(income)

• agesq: age^2

• lcigpric: log(cigprice)

Notes

If you want to do a “fancy” IV version of Computer Exercise C16.1, you could estimate a reduced form count model for cigs using the Poisson regression methods in Section 17.3, and then use the fitted values as an IV for cigs. Presumably, this would be for a fairly advanced class.
