Description

Wooldridge Source: L.E. Papke (1995), “Participation in and Contributions to 401(k) Pension Plans:Evidence from Plan Data,” Journal of Human Resources 30, 311-325. Professor Papke kindly provided these data. She gathered them from the Internal Revenue Service’s Form 5500 tapes. Data loads lazily.

Usage

Format

A data.frame with 1534 observations on 8 variables:

• prate: participation rate, percent

• mrate: 401k plan match rate

• totpart: total 401k participants

• totelg: total eligible for 401k plan

• age: age of 401k plan

• totemp: total number of firm employees

• sole: = 1 if 401k is firm's sole plan

• ltotemp: log of totemp

Notes

This data set is used in a variety of ways in the text. One additional possibility is to investigate whether the coefficients from the regression of prate on mrate, log(totemp) differ by whether the plan is a sole plan. The Chow test (see Section 7.4), and the less restrictive version that allows different intercepts, can be used.
