TheNepal2023WorldBankEnterpriseSurveyImplementationReport

I.Introduction

ThisdocumentprovidesinformationontheWorldBankEnterpriseSurveys(WBES)implementedinNepalbetweenMay2023andAugust2023.TheWBEScollectbothobjectivedatabasedonfirms’day-to-dayexperiences,andperceptionsofenterprisesregardingthebusinessenvironmentinwhichtheyoperate.TheWBEScurrentlycoverover195,000firmsin155countrieswithatotalofmorethan300surveyssince2006.TheWBESarealsousedtobuildapanelofenterprisedatathatwillmakeitpossibletotrackchangesinthebusinessenvironmentovertime.1

Thisreportdescribesthesamplingdesignofthesurvey,thedatasetstructureaswellasadditionalinformationthatmaybeusefulwhenusingthedata,suchasinformationonsurveynon-responseandtheappropriateuseofthesamplingweights.

II.SamplingStructure

TheWBESusestratifiedrandomsampling,wherethepopulationofestablishmentsisfirstseparatedintonon-overlappinggroups,calledstrata,andthenrespondentsareselectedthroughsimplerandomsamplingfromeachstratum.ThedetailedmethodologyisprovidedintheSamplingNote.2Stratifiedrandomsamplinghasseveraladvantagesoversimplerandomsampling.Inparticular,it:

?producesunbiasedestimatesofthewholepopulationoruniverseofinference,aswellasatthelevelsofstratification

?ensuresrepresentativenessbyincludingobservationsinallofthosecategories

?producesmorepreciseestimatesforagivensamplesizeorbudgetallocation,and

?mayreduceimplementationcostsbysplittingthepopulationintoconvenientsubdivisions.

TheWBEStypicallyusethreelevelsofstratification:industryclassification,establishmentsize,andsubnationalregion(usedincombination).Startingin2022,theWBESbasestheindustryclassificationonISICRev.4(withearliersurveysusingISICRev.3.1).3Forregionalcoveragewithinacountry,theWBEShasnationalcoverage.

II.1StratificationCategories

TheNepal2023WBESusesthefollowingstratificationcategories:

?Industry:4categories:

?Manufacturing

?Withinservices:Retail,Hotels,andOtherServices

?Size:3categories:Small(5to19employees),Medium(20to99employees),Large(100ormoreemployees)

?Region:3categories:Central,West,East

Alltheestablishmentsactiveinthemanufacturingsectorwerestratifiedinthesamecategory,namely‘Manufacturing’.AccordingtothemostrecentavailableNationalEconomicCensusinNepal(dating2018),themanufacturingsectorcovers27%ofthewholeWBESuniverseintermsofnumberofestablishments.

Thestratafortheservicessectorwereselectedbycontributiontothetotalnumberofestablishments,usingtheinputsfromtheNationalEconomicCensus.Thesectorsstratifiedseparatelyrepresent47%ofthetotalnumberofestablishmentsintheservicessector(36%retailand11%hotels),and34%ofthewholeWBESuniverse.

Becauseoftheabsenceofreliableofficialorsecondarysources,theSamplingFramefortheNepal2023WBESwasconstructedfromablockenumerationexercise(seecountsofestablishmentsintheframeinTable2)andfrominformationgeneratedinthemostrecentpreviousEnterpriseSurveyperformedinNepal.Morespecifically,thePanelSamplingFramewasconstructedusinginformationonalltheestablishmentsthatparticipatedintheNepal2013WBES.TheFreshSamplingFrame,i.e.,thelistofestablishmentsthatareintheWBESuniverseandthathavenotparticipatedintheNepal2013WBESwasobtainedviablockenumerationforallthesectors.BasedontheNepalEconomicSurvey2018andtoensurerepresentationofenterprisesfromall7provincesofNepal,16citiesfromall3geographicregionscoveredintheWBES(East,CentralandWest)wereselected.WesternNepalincludedBirendranagar,Butwal,Dhangadhi,Nepalgunj,andPokhara;CentralNepalincludedBanepa,Bhaktapur,Bharatpur,Birgunj,Hetauda,Kathmandu,Lalitpur,andSimara;EasternNepalincludedBhadrapur,Biratnagar,andItahari.Thesecitiesweredividedintolargeclustersbasedonthesmallestadministrativeunitalsoknownaswards.Awardisthesmallestadministrativeunitinacityorvillage.Atotalof334clustersorwardswereidentifiedinthefirststageoftheblockcreationprocess.Then,eachselectedcitywasdividedinto“blocks”usingGoogleEarthPro.Theaerialmapswithwardboundarieswereusedforthispurpose.Allthedenselypopulatedwardsweredividedintoseveralblocksfortheeaseofthelistingprocess.However,incasesofsmallclusterswithlowdensity(offirmsorenterprises),
