If the answer is yes then remittance y th ju promotes or inhibits the expenditure and how it affects to consumption section yi Studying this impact of remittance flows on recipient households has important pl ua al implications Understanding the impact of remittance flows to expenditure will help raise awareness about the positive as well as the negative that we can promote n n va appropriate policy ll fu oi m 1.2 RESEARCH OBJECTIVES The major objective of this study is to identify the impacts of remittances on the nh at expenditure structure of Vietnamese recipient households The study also aims at z z offering policy recommendations regarding foreign employment and an effective use vb of remittances ht k jm Base on the question, we will focus on the two hypotheses tested by the OLS

which can be increase or decrease, or even w unchanged according to the fluctuation of remittances receipt To examine at the n lo household level, we use the VHLSS – Vietnam Household Living Standard Survey ad conducted by The General Statistics Office (GSO) of Vietnam every two year In the y th ju thesis, we will use the most updated VHLSS data published in 2012 yi The study is narrow to the spending of the household, classified into two groups, pl ua al receive or not receive the remittances Source of remittance are come from the international migrants and the internal remittances from domestic migrants n n va The expenditure structure is classify to six main categories include food ll fu consumption, consumer goods, education, health, housing facilities and durable goods oi m 1.4 STRUCTURE OF THIS THESIS nh at The paper is structured in chapters and each chapter will cover the following z z content Chapter gives the introduction about the research topic including the overall vb information of remittances and theirs effects; the research objectives to find out what ht k jm should be focused on this paper Chapter briefly introduces the migration patterns gm and remittances in Vietnam, Chapter is some literature review covered the impact of l.c remittances on the household consumption structure from the previous researchers om Next, Chapter aims at explaining the methodology of research Chapter5 is the an Lu statistical models to discuss about the empirical analysis and present regression results and detailed explanation Finally, chapter gives a conclusion for what has been found n va and some policies recommended based on these finding ey t re th t to ng CHAPTER LITERATURE REVIEW hi ep 2.1 HOUSEHOLD UTILITY AND EXPENDITURE THEORY w The methodology of this paper is conducted base on the Engel curves Ernest Engel n lo (1821-1896) firstly introduced in his study published in 1857 for the basic theory ad y th between food consumption and the income of household He stated that, the spending ju on food would decline when the household income increase The relation between yi household expenditure and household income are mathematized as follow: pl ua al Ci=fi(X,Y,Z,U) (1) n where, Ci: expenditure on category i; X: total expenditure; Z: household va characteristic; Y: Income of household; u: unobservable variation n ll fu It represents the relationship between the household bud get shares changed by the oi m specific types of good to total household expenditure Using this model, the difference nh in consumption between households with different income can be observed To apply at this function to this study, income here can be understood by the remittances z z definition Based on the Engel curve, several functional forms have been proposed for vb jm ht the remittances variable For example, Deaton and Muellbauer (1980) used the Engel curves to exploit the relationship between remittances and spending; they found when k l.c remain the same, whereas the share of luxury goods increase gm income increases, spending for food decrease, spending for clothing, fuel, lightning fee om One of the most famous practical studies using the Engel curve, Working-Leser an Lu (Working, 1943, Leser, 1963) represented the model which is used as a foundation econometric model of this study The model describes the linearly relationship ey t re total household spending: n va between the budget shares of one certain expenditure category to the logarithm of the th (2) t to ng Table 9, most of the remittances are sending to the households living in the rural area, hi account of 60.78% per total households’ observation ep One considerable difference between two group, receive or not receive the w remittances can be well pointed with the household size With the non-recipient’s n lo household, the household size tends to be larger than the recipient household (have ad been proved in the table with Pr(|T| > |t|) = 0.0001 < 0.05 (5%) In the preliminary y th ju literature review, the motivation for migration and sending remittances back to home is yi mentioned Result in table can be considered a proof for this conclusion The more pl ua al dependent individuals in the household, the higher probability of people migrate and send remittance back to home Also, people who living in the rural and have migrants n n va in the family will have a higher probability to receive the remittances The results also ll fu show that, t test between the gender and employment has no significant meaning m For the preliminary step, we run the regression with the dependent variable is oi total per capita expenditure and the independent variables are the households’ nh at characteristic z z Table 10: Impact of some household
