| Tiivistelmä: | Using approximately 10,000 firms jointly covered by Compustat and CRSP from 1974-1993, the authors find substantial differences in the SIC codes designated by the two databases. More than 36 percent of the classifications disagree at the two-digit level and nearly 80 percent disagree at the four-digit level. The authors examine the impact of these differences upon financial research in several ways. First, the authors show that the classification of utilities, financial firms, and conglomerate acquisitions are affected by the choice of CRSP vs. Compustat SIc codes. |
