Abstract

This paper aims to examine how urban households’ food demand pattern differs with the extent of urbanization using a cross-sectional survey in southwest Nigeria. Using principal component analysis, sampled households were categorized by urbanicity index. A quadratic almost ideal demand system (QUAIDS) was employed to estimate expenditure and price elasticities. From the result, all seven food groups were normal goods across the urban categories, with the meat group being more expenditure-elastic than the others (1.16–2.42). The own-price elasticities differ among food commodities, with the meat and roots/tubers groups being most elastic at the low (−1.35) and middle (−1.05) urban categories, respectively. Findings suggest that changes in urbanicity levels have a substantial impact on the composition of household food demand and, by extension, the extent of food access in Nigeria. Therefore, the use of aggregate demand estimates for the entire urban population might underestimate the effect of expected changes in the urbanization level on food demand.

尼日利亚粮食需求及其对家庭粮食获取的差异影响

本文旨在利用尼日利亚西南部的横断面调查来研究城市家庭的粮食需求模式如何随城市化程度而变化。采用主成分分析方法，按城市化指数对样本家庭进行分类。利用二次型几乎理想需求系统(QUAIDS)来估计支出和价格弹性。从结果来看，所有七个食品类别都是城市类别的正常商品，肉类类别比其他类别更具支出弹性(1.16-2.42)。粮食商品的自身价格弹性各不相同，肉类和块根/块茎类的弹性分别在低(- 1.35)和中(- 1.05)城市类别中最大。研究结果表明，城市化水平的变化对尼日利亚家庭粮食需求的构成产生了重大影响，进而影响了粮食获取的程度。因此，对整个城市人口使用总需求估计值可能会低估城市化水平预期变化对粮食需求的影响。JEL分类:C31, D12, Q18

期刊介绍： Studies in Microeconomics seeks high quality theoretical as well as applied (or empirical) research in all areas of microeconomics (broadly defined to include other avenues of decision science such as psychology, political science and organizational behavior). In particular, we encourage submissions in new areas of Microeconomics such as in the fields of Experimental economics and Behavioral Economics. All manuscripts will be subjected to a peer-review process. The intended audience of the journal are professional economists and young researchers with an interest and expertise in microeconomics and above. In addition to full-length articles MIC is interested in publishing and promoting shorter refereed articles (letters and notes) that are pertinent to the specialist in the field of Microeconomics (broadly defined). MIC will periodically publish special issues with themes of particular interest, including articles solicited from leading scholars as well as authoritative survey articles and meta-analysis on the themed topic. We will also publish book reviews related to microeconomics, and MIC encourages publishing articles from policy practitioners dealing with microeconomic issues that have policy relevance under the section Policy Analysis and Debate.
