Disease and Development: The Effect of Life Expectancy on Economic Growth

Daron Acemoglu and Simon Johnson*Journal of Political Economy *115, December 2007: pp. 925-985.

Below are two sets of program files for reproducing the results in *Disease and Development**. *The first, under the heading "Program Files for Use with Stata 10 or higher," will exactly reproduce the paper's results when used with Stata 10 or higher, but will not reproduce the paper's results when used with Stata 9 or lower. We realized after the paper's publication that the Stata procedure used to calculate standard errors with the *xtreg* command - used throughout the paper - was changed between Stata 9 and Stata 10. In all version of Stata prior to Stata 10, the commands *xtreg *and *areg *estimate identical standard errors, as both correct for the degrees of freedom used in estimating fixed effects. In contrast, in Stata 10 and higher, *xtreg *does not correct for the degrees of freedom used to estimate fixed effects, while *areg *corrects for the degrees of freedom used to estimate fixed effects in all versions of Stata. Thus *xtreg *in Stata 10 and higher produces standard errors somewhat smaller than those produced by *areg i*n all versions of Stata or by *xtreg *in Stata 9 and lower, and *Disease and Development *can only be reproduced using Stata 10 or higher. (Tables 8 and 9 also use a small sample correction for the standard errors that is only available in Stata 10 or higher.)

For comparison purposes, the second set of program files below, entitled "For use with any version of Stata", uses *areg *and will produce identical estimates regardless of which version of Stata is used, as *areg *always corrects the standard errors for the degrees of freedom used to estimate fixed effects. However, these programs will not reproduce the paper's results since they were estimated with *xtreg* in Stata 10. For more information about the changes in the *xtreg *procedure in Stata 10, and about the *areg and xtreg *commands more generally, please see the Stata manuals.

**Software requirements: **Stata 10 or higher to reproduce the standard errors in the paper.
