We consider firms' choices between a clean technology that benefits, and a dirty technology that harms, the environment. Green firms are more suited to the clean, and brown firms are more suited to the dirty technology. We use a model derived from complexity theory that takes account of true...

We consider technology choices between green and brown technologies by firms. We use insights from complexity theory and also take account of true uncertainty in designing public policy. The green technology offers relatively higher returns to scale from adoption, and there are type-contingent...

In the light of a changing climate, resilient coffee varieties and adoption of improved agricultural practices are needed. Agronomic studies have promoted the first generation of Coffea arabica hybrid cultivars (F1 hybrids) as resistant to pest and diseases and able to grow under shade. Thus,...
