Quasi-Concave (Composition) Functions with Nonconcave Argument Functions

The concavity assumption in the known composition mapping result may be too restrictive for certain applications in the household production model and trade theory. We show how quasi-concave composition functions are generated when among the arguments are nonconcave but still quasi-concave functions...
