This file contains the skill-relatedness estimates that are derived in the article “Skill-relatedness and firm diversification.” In the article, labor flows to newly established plants are excluded from the analyses to avoid any circularity in the calculation of skill-relatedness and diversification events. However, in this version, we maximize the available information and also include the labor flows to new plants when calculating skill-relatedness. The file consists of four columns:

(1)     ind_1: SNI03 (NACE 1.1) code for the industry of origin
(2)     ind_2: SNI03 (NACE 1.1) code for the industry of destination
(3)     SR: skill-relatedness from the industry of origin to the industry of destination
(4)     p: p-value of SR

For a detailed description of the methodology behind the skill-relatedness estimates and the calculation of the p-values, you are referred to the article and its supplementary online material. Any use of these data should be accompanied by the following reference:

Neffke FMH, Henning M. forthcoming. Skill-relatedness and firm diversification. Strategic Management Journal.

Please update this reference once the article has been published by Strategic Management Journal.
