Quasi-concave (composition) functions with nonconcave argument functions Raul V. Fabella. p. 473-477 The concavity assumption in the known composition mapping result may be too restrictive for certain applications in the household production model and trade theory. The author shows how quasi-concave composition functions are generated when among the arguments are nonconcave, but still quasi-concave, functions.
