Description

mizr: Six 57 by 57 matrices.

BACKGROUND Mark Mizruchi collected these data in the late 1980s. He recorded a great many attributes of major corporations as well as data on their similarities and differences. Six data matrices are reported here. SAME_STATE tallies those pairs of corporations that are headquartered in the same state. SAME_INDUS records those who are in the same industry. COMM_STKHLDRS is the natural logarithm of the number of stockholders that own at least 0.5 percent of the stock in both firms. DIR_INTERLKS is a record of the number of individuals who sit simultaneously on the boards of directors of both firms. INDIR_INTERLKS records the number of leading banks and insurance companies that have interlocks with both firms. And JOINT_CONTRIBUTION is the number of candidates for office who received contributions from both firms.
