    /, #esults anddiscussions

     The results and findin$s of this study& hich are thematically or$aniDed& sho ho e"#rocurement miti$ates public procurement fraud in !alaysia. The emer$ent themesshoed that e"#rocurement4 ,1- can escape the influence exercised by political and

    economic forces hen reardin$ $overnment contracts& ,2- mana$e demands andinterference from third parties& and ,- is useful at the nexus of public"private relations.

    /,1 Political andeconomic orces

     The interest of political and economic forces in $overnment procurement takesthe form of fraudulent activities and corruption in the public offices ,Cose";ckerman&1===-. ; number of previous studies shoed the role of political and economic forcesand poer relations in deviatin$ the principles of transparency and accountability in aprocurement process ,(astidar and !ukherjee& 2016& Thai& 200=-. or example& theprotectionist policy hich has been implemented in !alaysia to favour domestic

    companies has to some extent resulted to fraud and corruption activities. raud andcorruption in !alaysian public procurement is associated ith the entrenched poer of political and economic institutions in distributin$ public resources. n this context& onecan say that distribution of public funds may open up an opportunities for fraudand corruption throu$h rent"seekin$ activities& political patrona$e& cronyism andfavouritism ,+omeD et al.& 201& /undaram and ui& 2010-. %hat is more& hen theprocurement biddin$ process is not transparent& but there is conflict of interest& a biddercan be selected not due to their capacity but due to their relation ith the rulin$ party,Ghalid& 2016& %elsh and 5hin& 201-. Therefore& *"#rocurement helps reduce the riskof abuse& fraud and corruption by $ivin$ transparent information from all bidders.

    E-Procurement helps b sho!in" that onl relevant bi##ers can bi# for selective "overnment contracts$ If the bi##ers have not submitte# all therelevant re%uirements to the sstem &for e'ample the #i# not provi#e the(inistr !ith the har# an# soft copies of procurement #ocumentation)* !e !illautomaticall !ith#ra! their application$ This is clearl state# in all"overnment purchasin" instructions an# it is a##resse# to all bi##ers in e-Procurement$+ 

    %ith e"#rocurement& the system obli$es the bidders to submit all the relevantinformation. ailin$ to do so& the system automatically rejects the application&re$ardless of hoever may favour a particular bidder. ence& a transparent process of selectin$ and rejectin$ the bidder makes it possible to miti$ate fraudulent practicesithin the procurement life cycle.

    ?ext& the ability of e"#rocurement process to be unbiased toards certain $roups ,frompolitical and economic institutions- helps reduce the level of fraud and corruption in$overnment contracts. t is said that feer interactions ith the potential bidders mayprevent the bribes and kick"backs& collusive biddin$& mispricin$& conflict of interestsituations and many other fraud schemes in public procurement ,5aulfield& 2016& %orldank& 201-. n relation to that& Ce$ulator 10 stated that&

    3,*onclusion

     Throu$h the lens of the political economy approach this research sheds li$ht on ho e"#rocurement is able to curb public procurement fraud in !alaysia. The findin$sindicate that ,1- e"#rocurement can be used as a3$atekeeper) for all bidders in ensurin$ that they follos the 3rules) as stipulated in the

    system. y usin$ e" #rocurement& the bidders must comply ith all rules otherisetheir application ill simply be rejected ,;laeti et al.& 201-. The system is notbiasedL rather it chooses the best value for money contract. Thus& e" #rocurement is ableto stop any political and economic forces from interferin$ ith procurement processes.,2- e"#rocurement helps to safe$uard many public officials throu$h its transparent andeicient system. t can be used as a 3barrier) to avoid unnecessary demands andinterference from people ith a vested interest. ,- e"#rocurement is also useful indealin$ ith intertined relationship beteen public and private or$aniDations. (espitefacilitatin$ business to business transactions& e"#rocurement does not compromise theay they do business. The system 3demands) and makes it compulsory to the supplier to$ive proof of their capability to do specialiDe thin$s for $overnment a$encies ,e.$. proof of experience& certificates of 'ualifications-. Therefore& businesses cannot simply $etaay ith fraudulent transactions by havin$ connections ith the poerful $roup. The system is clear and unbiased& ith feer human interactions. Therefore& e"#rocurement can be used to minimiDe the risk of public procurement fraud.

     The paper has taken a 'ualitative approach in explorin$ the vies and perspectivesof !alaysian public oicials in relation to the aids of e"#rocurement in alleviatin$ fraudin the public offices. The most important contribution of this study is that it explored and$ained an understandin$ of this very difficult matter from the personal experiences of 1 procurement officers. ;s such& the study as able to $ather professionalknoled$e that is often confidential& privile$ed and hidden from the public domain,5hristopoulos& 200=-. Therefore& the efficient use of /noball /amplin$ Techni'ue ,//!-for the current study si$nificantly contributed to the investi$ation of this socialphenomenon. The detailed implementation of //! ,as explained in methodolo$y

    section- can be considered by other researchers& too. n re$ard to this& the richmosaic of vies on curbin$ public procurement fraud throu$h e"#rocurement can havepractical implementations and contributions for policy makers& enforcement a$enciesand researchers. urther& the political economy approach $ives fruitful evidence to3unpack) the praxis of e"#rocurement in curbin$ public procurement fraud in !alaysia.
