题目:Non-Homothetic CES Preference with General Parametric Restrictions


摘要:The non-homothetic CES preference with the standard parametric restriction is against the empirical observation of declining sectoral expenditure shares in many economies. This paper introduces a non-homothetic CES preference with a general parametric restriction that is consistent with these empirical patterns. We fully characterize this general non-homothetic CES preference and demonstrate that it preserves all the desirable properties of the standard non-homothetic CES preference. We also show that this preference is not restrictive for conducting empirical and quantitative analysis. We establish that the normalization strategy is unknown prior to estimation, which undermines the identifiability of the implicit Marshallian demand. We develop a method that utilizes Hicksian demand to address this issue. Our findings imply that the general non-homothetic CES preference is flexible in sectoral income elasticities and more capable of matching empirical patterns along the process of structural transformation.
