英文文献：The "Constant Difference Of Elasticities" (Cde) Functional Form: A Neglected Alternative
英文文献作者：Surry, Yves
英文文献摘要：
Unlike those flexible functional forms which are local approximations, the "Constant Difference of Elasticities" (COE) function is globally well-behaved. Due to its theoretical properties and parsimony in the number of parameters, the COE functional form offers many potential applications in pro.duction, consumption and trade analysis.
