Dukpa Kim and Tatsushi Oka, "Divorce Law Reforms and Divorce Rates in the U.S.: An Interactive Fixed Effects Approach", Journal of Applied Econometrics, Vol. 29, No. 2, 2014, pp. 231-245. The data used in this article are based on the dataset used by Justin Wolfers, "Did Unilateral Divorce Raise Divorce Rates? A Reconciliation and New Results", American Economic Review, 96(5), December 2006, 1802-1820. To create the balanced panel data, we conduct interpolation as discribed in the Appendix. All data are in the file ko-data.txt, an ASCII (text) file in DOS format. It is zipped in the file ko-data.zip. Unix/Linux users should use "unzip -a". The file ko-data.txt contains the following variables; Column 1: State (two-letter abbreviation) Column 2: Year (1956-1998) Column 3: Divorces per 1000 people Column 4: logarithm of Divorce per 1000 people Column 5: Divorce law reform dummy (First 2 years) Column 6: Divorce law reform dummy (3 - 4 years) Column 7: Divorce law reform dummy (5 - 6 years) Column 8: Divorce law reform dummy (7 - 8 years) Column 9: Divorce law reform dummy (9 - 10 years) Column 10: Divorce law reform dummy (11- 12 years) Column 11: Divorce law reform dummy (13- 14 years) Column 12: Divorce law reform dummy (15 years or more)
