Introduction Families spend money in variety patterns. Small size family consisted of nuclear family needs less goods than large size family. Therefore, spending pattern of small family is different with the large one. This paper is aimed to find out current and past research regarding to what extent family size affect to spending pattern. Background research Prior research shows mix result. Bojer (1977) discover that a family consisted two adult and two children spent 2.5 times higher than a single adult. Likewise, Lino (1994) compares spending patterns of single mother families. The research shows that total expenditure of married couple with children was around 40% higher than single mother families. While, Lazear and Michael (1980) argue …show more content…

Working (1943) introduced model of functional form of Engel curve parametric analysis. This model easily measured the economies of household size based on food expenditure (Gibson 2002, Lancester, Ray, and Valuezuela 1999). They conclude that the larger households the smaller share on spending food of their total expenditure. The second model is introduced by Barten (1964). This model allows for substitution between food and non-food (Lancester, Ray, and Valuezuela 1999). Methodology There are several researches conducted by scholars using those two models. Barten’s Model Authors Description of study Conclusions Mok, Maclean, and Dalziel (2011) The degree of economies of scale for different goods depends upon household expenditure and household composition Validating Barten’s model in estimating the household economies of scale Deaton and Paxton (1998) Total expenditure per capita held constant, expenditure per head on food falls with the number of heads Empirical evidence is exactly opposite of the theoretical predictions Gan and Vernon (2003) study an inconsistency between the model and the data in Deaton and Paxson (1998) Empirical evidence confirms that the food share increases with household size relative to more public goods and decreases relative to more private goods, and the elasticity of the food share with respect to family size decreases as households become …show more content…

Gan and Vernon (2003) is one of the scholar who give comment on Deaton and Paxson research. By using the same assumption with Barten, their study shows that food share rise with household size. Therefore, it confirms Barten’s model. Furthermore, Deaton and Paxson rebut on Gan and Vernon claim. They state that their description is not clear and does not resolve the paradox (Deaton and Paxson 2003). The researchers claim that their objective is not testing the Barten model. Conclusion Variety of spending pattern in a family can be measured based on the size of the household using Barten model or Engel model. Even though Deaton and Paxson (1998) study claim there is a paradox, the two model well established to predict that the food expenditure is positively correlated with household
