Chief and coercionemost, we would love to specific our gratefulness to entire those who gave us the possibility to completion this inquiry. We would love to transmit our candid docommonwealth to our lecturer Ms. Dao Thanh Binh, PhD, lecturer of Faculty of Management and Tourism, Hanoi University, coercion her equiconsideration and consecrated lectures. Extinguishedside her requirely scholarship, this inquiry canreferable attribuconsideration attribuconsideration attribuconsideration attribuconsideration be courtly. Our deepest gratefulness besides goes to our cherished preceptor Ms. Tran Kim Anh, aggravatecome. Her dedicated instructions and livelihood were of wide acceleration.
Outside her heart-felt protection and fearlessness, this essay would referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration be able to succeeding to this fruit. Abstract In modern years, Vietnam’s inflation has extensiond to an ominous scpreceding of couple-digit, ranking itself feature of 5 estimateries having the pre-eminent inflation scpreceding in the earth. That Squanderr Charge Condemnation (CPI) has incessantly escalated is the primitive deduce coercion such worrying manifestation. Our design, hence, is aimed at investigating and analyzing Vietnam’s CPI by proofing the collision of succeedingcited constituents on CPI: USD/VND modify scold, petrol charge, rice charge and prevalence yield.

Henceforth, a pauserainteannouncement abextinguished inflation scpreceding intention from CPI and innate constituents decomposition may be given to acceleration us amend classify coercion examples that can aloosen as a fruit of grievous inflation. The pattern that can best illustscpreceding intercommunity incomplete the fractions veerables and CPI has been descryed. Basing on our inquiry, it is likely that those foul-mouthed veerables entertain a gravityous wave on Squanderr Charge Condemnation.

Introduction Coercionevery vulgarwealth earthwide has coercionforever confronted with inflation and attempting to unfpreceding inflation example.
Vietnam is referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration an exclusion. Inflation has assayd to be feature of the most solicitous manifestations by twain Vietnamese empire and economists coercion almost a decade as it has attraction towards ceaselessly inflating past 2004. Inflation is an extension in aggravateentire charges of upshot and services in an husbanding aggravate a date of term. Inflation scpreceding during a year achieve probably loosen if there is a escalation in Squanderr Charge Condemnation (CPI) in that year comparing to ceegoing year, basing on succeedingcited coercionmula: InflationYear 2=CPIYear 2-CPIYear 1CPIYear 1
Therefore, agreement the sort of inflation and efficiently anticipating it can innately amend and confirm the husbanding in unconcealedly, potent calling towards amend policy, as polite-mannered-mannered as accelerationing race compound to charge modify in feature. Referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration simply is CPI a puissant machine coercion empire and economic experts to perceive-preserve the completion society’s smooth of decay, excepting it besides, past innately, coercionetell the inflation scpreceding that may entertain a innate collision on the completion husbanding as polite-mannered-mannered as the race’s daily lives.
According to Earth Bank and International Monetary Funds (IMF), stationary, Vietnam is listed in high-inflation zfeature with a becomeing CPI. As coercion IMF’s axioms, Vietnam’s CPI in August 2011 went up by 23. 02% compared to the identical month of 2010; CPI in December 2011 besides extensiond by 15. 68% compared to 2010. Besides, Vietnam’s husbanding has witnessed a concomitant boost in charge of upshot and petrol throughextinguished the year, concurrently with decreasing purchasing talentedness in modern years. Do these axioms show a poorly predicament coercion Vietnam? We probably do referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration apprehend coercion secure.
We, instead, can acceleration enunciate a past optimistic husbanding from the pauserainteannouncement of CPI as polite-mannered-mannered as inflation scpreceding of Vietnam. From such aggravatehead onlymn axioms and figures, this design is conducted to criticise Vietnam’s CPI and constituents innate CPI, then, giving pauserainteannouncement abextinguished Vietnam’s inflation scpreceding by coercionming an aggravateentire paint of abnormitys in race’s savetress compensation, thus further judging the possibility of inflation which may abolition flush a bulky husbanding of Vietnam ascribable to the prompting of hyperinflation. 2. Methodology 2. 1. Method of collecting postulates and other founts
As discussed antecedent and achieve be examined deeper succeeding in this essay, there are some constituents that denote an innate role in deciding the smooth of squanderr charge condemnation in Vietnam. They halt of the move of modify scpreceding (specifically, the USD/VND modify scold), the charge of petrol in Vietnam which is very nice, the Vietnamese rice charge and empiauthentic prevalence yield. Through the application of econometric theories concurrently with the examicommonwealth of each personal constituent, the pattern can be coercionmed as follow: CPI=? 1+? 2? ER+? 3? P+? 4? R+? 5? MS+?
In classify to gather the referable attribuconsideration attributableice respecting the foul-mouthed constituents (fractions veerables), a calculate of postulates entertain been attentive in the date 2000 – 2010: * The annual Vietnamese USD/VND modify scold; * The annual Vietnamese rice charge; * The annual prevalence yield of Vietnamese empire and other institutions; * The annual petrol charge of Vietnam. Entire the postulates self-possessed entertain been establish from several founts on trusted websites, in which we can estimate on the reliability and atonement of the statistics and other cognate referable attribuconsideration attributableice. 2. 2. Methods of processing the postulates The postulates self-possessed aggravatehead are discussable bald postulates.
Therefore, in classify to constitute pauserainteannouncement abextinguished the smooth of CPI in Vietnam correspondently, some processes and care securely ask-ce to be made. Chief term, the bald postulates ought to be processed through the talentedness of such hesitateenceal machines as Eview and Microsoft Excel. Featurely, Microsoft Excel achieve acceleration designate the tend in the fractions veerables (modify scold, rice charge, prevalence yield and petrol charge) as they modify throughextinguished the years and other certain hesitateence coercionasmuch-as Eview and its econometric cares further in figuring extinguished some nice indicators (t-statistic, R squared, disposeed R squared, p-value, provision. . Succeeding having those calculates and indices, couple proofs (the t-proof and the f-test) are professionally rightd to constitute extinguished referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration simply the position of opinion of each fractions veerable excepting besides the aggravateentire mediumingfulness that entire the fractions veerables subscribe to the determicommonwealth of CPI. From then on, it should be past seasonable coercion us to constitute some provision abextinguished the tend of CPI in Vietnam domiciled on the processed postulates we made. 3. Postulates decomposition 3. 1. Squanderr Charge Condemnation Figure [ 1 ]: Vietnam CPI from 2000 to 2010
Chief of entire, the squanderr charge condemnation (CPI) measures of the aggravateentire require of the upshot and services bought by a normal squanderr. In certainty, it provides referable attribuconsideration attributableice abextinguished charge modifys in the vulgarwealth’s husbanding to empire, calling, strive and peculiar citizens and is rightd by them as a superintend to making economic decisions. Hence, analyzing CPI is very innate this aids in coercionmulating fiscal and monetary policies. As can be visitn from the chart, there was a polite-behaved-regulated extension in the CPI from 2000 to 2010. In other tidings, the normal mount has to squander past dollars to detain the identical emblem of savetress during 10 years.
To designate, succeeding undergoing a disregard augmentation in the chief foul-mouthedth years from 100 to abextinguished 110, CPI extensiond gravityously to a peak of environing 210 in the conclusive year. There are manifpreceding constituents including modify scold, prevalence yield, rice charge and petrol charge which creator this augmentation in CPI are entity solicitous. 3. 2. Modify scpreceding Figure [ 2 ]: Vietnam’s USD Modify scpreceding from 2000 to 2010 According to the postulates compiled from 2000 to 2010, the modify scpreceding of USD/VND skilled an upward tend. In 2000, the USD/VND modify scpreceding was VND 14,170, then extensiond by 4% and 5% in 2002 and 2003 respectively.
From 2003 to 2008, the modify scpreceding remained firm environing VND 15,700 which can be elucidateed by some rationales. Chief of entire, Vietnam mediate bank manipulated the negotiate by selling USD and dressed to adculm the modify scpreceding unnatural in succeedingcited years (vietcombank, 2002). Pastover, ascribable to the US economic wavering and USD derogation dehatred other currencies, VND depreciated short than expected. In 2009, the modify scpreceding underwent a surge to VND17, 066 and continued increasing dramatically to VND 18,620 in 2010.
Though the mediate bank implemented manifpreceding policies to stabilize the modify scold, it quiet rose gravityously past manifpreceding citizens had speculated the USD and waited until it appreciated ample past dehatred VND (scribd, 2010). Another deduce is the authentic ask-ce in USD ascribable to the extension in proper products and labours. According to Mr Nguyen Van Binh, crime chairman of the Mediate Bank, increasing modify scpreceding is an talented machine crafted by the mediate bank to boost ship-produce and economic enunciatement (luattaichinh, 2009). 3. . Petrol charge Figure [ 3 ]: Vietnam’s vend petrol charge from 2000 to 2010 According to the postulates accumulated, the gasoline charge unconcealedly has an upward tend though the 11-year date from 2000 to 2010 Aggravate the chief 4 years from 2000 to 2003, the charge of gasoline remained the identical or modifyd referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration ample. The 4 years of charge arrestation had skilled the dramatic modify, which was a bulky extension to 122. 2% in 2006 (from 5,400 to 12000 VND). From that subject-matter of term, the gasoline charge disregardly felt to 11,300 in 2007.
This is, stationary, followed by a gravityous augmentation from 11,300 to 16,320 VND in 2008 and fluctuated in the protraction of 2008 and 2010. In omission, the charge of gasoline in Vietnam is coercionetelled to be continuing to become aggravate the contiguous scant years. 3. 4. Rice charge Figure [ 4 ]: Vietnam’s rice charge from 2000 to 2010 According to the postulates compiled, the rice charge has an upward tend though the 10-year date from 2000 to 2010. The charge of rice spreceding was fairly polite-behaved-regulated aggravate the chief 3 years from 2000 to 2003 with a disregard loosen to 100. 6%. This arrestation was followed by a quick extension to 122. % in 2006. This tend was confirmedby the certainty that Vietnam became an characteral component of Earth Dealing Organization (WTO) in 2007( BBC 2007), which rocketed Vietnam’s inflation to 12. 6% (ThuyTrang 2008). In pauseitution, 2007–2008 earth stay charge crises subscribed a sepatrounce in the augmentation of earth stay charge in unconcealed and rice charge in Vietnam in feature ( Compton provision. 2010, p. 20), superfluous to a observable loosen on Vietnamese rice charge to 215. 2% in 2008, and 251. 8% in 2010. To mix up, the Vietnamese rice shot up aggravate 2. 5 stipulations from 2000 (100%) to 2010 (215. %) and this tend is surmised to quiet preserve going on in contiguous scant years. 3. 5. Prevalence yield Figure [ 5 ]: Vietnam’s prevalence yield from 2000 to 2010 (in VND billion) Starting with almost $ 200,000 billion in 2000, the completion of prevalence in the husbanding adage a disregard loosen incomplete 2001 and 2004 excepting prevalence yield quiet hesitateior than $ 500,000 darling, anteriorly importance with a gravityous extension coercion the conclusive date and reaching at $ 2,478,310 billion in 2010. With the completion of prevalence in negotiate increasing by from 15% to 50% each year; Vietnamese entertain past prevalence to squander and charge smooth besides unnatural. 4.
Pattern mention 4. 1. Veerables and intercommunitys In classify to con-over the moves of CPI in Vietnam, it is innate to evaluate the constituents that instigate the modifys in CPI. a) USD/VND modify scpreceding It is easily visitn that Vietnam has proofed from a wide dealing nonpayment which resources purport entity past than ship-produce. Hence, if the modify scpreceding USD/VND extensions, which can be elucidateed as VND depreciates dehatred USD; purported products achieve be past valuable than anteriorly. Past purported products exceed proper products, Vietnamese squanderrs entertain to proof from surpassing charge of entire purported products.
By that, domiciliary producers as the fruit achieve charm usage of this gravity to extension the charge of domiciliary products to rival with other coercioneign products. Tradable upshot entity half the basket of the CPI achieve extension the charge which manages to the surge in the CPI. b) Petrol charge Almost entire the products at-once or inat-once ask-ce the right of petrol as the ocean fuel coercion mien, origination or yield fuel coercion electricity, coal, provision. If the charge of petrol extensions, the require of origination achieve proof a loosen as polite-mannered.
Hence, the producers achieve extension the charges of upshot to requite coercion the extension in origination require which subscribes to surpassing CPI. c) Rice charge Feature of the ocean categories that are interjacent in the basket of upshot when sagacious CPI is stay. Vietnam is a estimatery where race squander rice as the ocean stay in daily meals, thus the modify in rice charge achieve like the CPI of Vietnam. d) Prevalence yield Conclusively, as CPI is heavily trusting on the charges of upshot and services, prevalence yield is besides feature of the constituents that entertain importance on CPI.
This can be elucidateed by the certainty that the surpassing yield of prevalence there is on the negotiate, the hesitateior the appraise of Vietnam prevalence is. As Vietnam Dong depreciates, charges of upshot and services achieve be surpassing and crime versa. As a fruit, prevalence yield modifys manage to CPI modifys. 4. 2. Pattern adoption From the identification of the constituents innate CPI aggravatehead, the veerables achieve be denoted as follow: CPI: Squanderr Charge Condemnation ER: Modify scpreceding of USD/VND P:Petrol charge R: Rice charge MS:Prevalence yield
A calculate of feasible patterns are ancilla coercion the inquiry, and in classify to evaluate the misspendness of each pattern, we domiciled on 2 criteria: * R2: Coefficient of indulgent: The percentage of abnormity in CPI is elucidateed by the pattern. * CV: Coefficient of abnormity: The medium fault of the specimen retreat employment referring-to to the medium of Y. The pattern with surpassing R2 and hesitateior CV is amend. a) Lin-Lin pattern CPI=? 1+? 2? ER+? 3? P+? 4? R+? 5? MS+?

There is referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration plenty illustration to hesitate the awaitence of second-classify autocorrelation. In pauseitution, we besides referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attributableice that the p-appraise of chief-classify is wideer than 0. 5, thus the chief-classify autocoragreement does referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration await either. To mix up, there is no autocoragreement fault in the pattern. 7. Omission Succeeding fully investigating patterns and their gravityous, it can be hesitatered that the best misspend pattern, which can polite-mannered-mannered elucidate the intercommunity incomplete CPI and innate constituents, is the succeedingcited feature: CPI=49. 84103+0. 00083? ER+0. 00217? P+0. 236729? R+0. 00002? MS Basing on the decomposition, the pattern is assayd to rather constitute view as the certainty that three fractions veerables, including petrol charge, rice charge and prevalence yield, likelyly like Vietnam’s CPI.
Succeeding proofing, the USD/VND modify scold, at-last, is distinctly secondary. Consequently, the modify scpreceding is deduceably fallped extinguished of the pattern. Pastover, entire fractions veerables entertain dogmatical intercommunity with CPI past the extension of any veerables may fruit in augmentation of CPI. Besides the talentedness and mediumingfulness of the pattern, faults and constraint quiet await. Multicollinearity is establish extinguished to be the considered manifestation, stationary, it is surely obscure to entertain any suiconsideration alterative. And, couple pause faults including heteroscedasticity and autocoragreement are shown referable attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration attribuconsideration to await.
It is the certainty that the pattern is necessary to some faults and constraints, excepting these examples visitm trite and disregard. From aggravatehead criticised postulates, the fractions veerables give a vulgar tend of increasing, which manages to attraction of CPI to loosen as polite-mannered. Hence, we stand that the CPI coercion the contiguous years achieve boost. Dehatred Vietnamese empire’s innate efforts to abstain the inflation scold, it is quiet innately prfeature to escalate as a fruit of ineviconsideration tend.
