摘要
Differences between SIC codes assigned to companies by COMPUSTAT and CRSP are examined. Large differences are observed at two-, three-, and four-digit levels. Correlations of intra-industry monthly stock returns are larger, and variances of intra-industry financial ratios are smaller for industries based on COMPUSTAT codes. Replication of a portion of Freeman and Tse (1992) produces significant results using COMPUSTAT codes, consistent with the original research, but insignificant results for CRSP codes.
