“…Few studies have been directed to demand analysis of UIVs. Previous studies on food demand have made use of double logarithm functions, almost ideal demand and its variants (Akinleye, 2009;Oyekale, 2000;Tsegai and Kormawa, 2002), and quadratic almost ideal demand (QUAID) systems (Obayelu et al 2009). Few of these studies investigated demographic factors influencing demand.…”

“…Chiew (2007) identified poor dissemination of price information, including specific item price, prices of closely related products, and major determinants of demand for vegetables, as causes of ineffective production planning, which has led to wide price fluctuations. Previous studies focused on demand analysis of food systems in general (Akinleye, 2009;Fashogbon and Oni, 2013;Olorunfemi, 2013). Studies by Ogundari and Arifalo (2013) and Khaliukova (2013) have been on routinely cultivated vegetables.…”

The use of QUAIDS with test and correction of expenditure endogeneity serves as value addition of this study apart from the fact that the study is being carried out in the rural part of Ondo state which is noted more for production of cash crop than food crop.…”

This study described the food demand of rural households of Nigeria with a view to identifying its determinants and responsiveness to price and household food expenditure.The study made use of 121 rural households in Ondo state using a 3-stage random sampling technique.Demand for food groups in this study was estimated using Quadratic Almost Ideal Demand System (QUAIDS). The Wald test revealed that the QUAIDS model was significantly corrected for endogeneity and that the inclusion of demographics in the model significantly improved estimates. Food group grains and starch basket had the largest share (49%) of household total food expenditure. Grains and starch was expenditure inelastic, animal protein was a luxury, Fruits and Vegetables group was inelastic, while Fats and Oils were elastic. Own price elasticities were all negative as expected in both uncompensated and compensated price elasticity estimates. The Hicksian cross-price elasticities showed that all food groups were net substitutes. Arising from the foregoing, the study concludes that animal protein group and fat and oil group are income responsive while others are inelastic. The study further revealed that all food groups are normal food and price inelastic with the exception of fats and oil (price elastic). Price, household size, total food expenditure, and expenditure on food away-from-home were key determinants of food demand among rural households in Ondo state.Therefore policy directed at increasing both farm income and non-farm income to increase expenditure and promote food security should be given more attention.

“…Wadud (2006) reported that during 1980-1991, as many as 89 empirical works used AIDS in the demand studies. In food consumption studies, AIDS has been widely used in several studies, such as: Tiffin and Tiffin (1999); Karagiannis et al (2000); Wadud (2006); Sheng et al (2008); Akinleye (2009) ;Obayelu et al 2009;Janda et al (2010).…”

“…However, empirical work focusing particularly on the vegetable demand has been sparse. In addition, the majority of Nigeria food demand studies treated "vegetables" as a single aggregate item within a demand system that includes other aggregated food items, like "meat" and "fish" products (Aromolaran 2004;Olarinde and Kuponiyi 2005;Rahji and Adewumi 2008;Akinleye 2009;Obayelu et al 2009;Tsegai and Kormawa 2009). Only similar studies, conducted outside Nigeria, by Belarmino (1983), Quisumbing (1985) and Mutuc et al (2007) used a number of more disaggregate vegetable categories (e.g., green, leafy, and yellow) rather than using a single aggregate "vegetable" category to investigate the food demand behaviour.…”

Fruit and vegetable consumption has been shown to be an important part of any diet leading towards good health, but little is known about the vegetable demand behaviour at fi ner levels of disaggregation in Nigeria. Hence, this study estimated the price and income (expenditure) elasticities of demand for the commonly consumed vegetables among households in the Ogun State, Nigeria. Data were collected with the use of a well-structured questionnaire administered to one hundred and twenty (120) households that were randomly selected using a multi-stage sampling procedure. Th e data were analysed by simple descriptive statistics and estimation of a Nonlinear Quadratic Almost Ideal Demand System (NQAIDS) of vegetable demand behaviour of households sampled. Th e results show that income elasticity of demand for Bitter leave (-3.43) and the Eggplant (-3.67) are elastic, while income elasticity of demand for Tomato (0.27), to which about one-third of vegetables expenditure are devoted, is inelastic. Th e results further revealed that own-price elasticities of demand carry the expected negative signs for all the vegetables and are generally inelastic. Estimates of cross price elasticities show the dominance of substitutability among the vegetables with only few cases of complementarities.
