Section 4: Marginal Probability of New Product
For New Product we find evidence of significant interaction for Linkages to Assemblers with
Tier 2 (larger impact on tier 2) and with Tier 3 (smaller impact on tier 3). The effect is
significant at the 0.05 level when linkages are above 20, and it is significant at the 0.1 level
between 5 and 15. In addition, we find evidence of significant interaction for Linkages to
Peers. In this case, the interactions with Tier 2 and with Tier 3 are significant at the 0.05 level
for linkages above 20 and at the 0.10 level below 20.
