Peer effect and environmental responsibility of enterprises in a sub-Saharan African country

The aim of this study is to evaluate the role of peer effects on the behavior of enterprises towards their environment. We use the approach of Instrumental variables (IV) to identify and estimate peer effects in industrial sector in Cameroon. This approach allows us to identify a mimetic behavior of enterprises in environmental protection when the reference group is the sector of activity. Thus, the impact of a policy of fight against environmental degradation is higher when the peer effect is taken into account in the sector of activity of the enterprise.
