The benefits of improved service quality-while significant-are often overlooked because they are difficult to quantify. This paper reviews methods of evaluating the welfare implications of changes in the quality of infrastructure services within the broader theoretical perspective of welfare measurement. The study outlines the theoretical assumptions and data requirements involved, illustrating each method with examples that highlight common methodological features and differences. The paper also presents the theoretical underpinnings and potential applications of a new approach to analyzing the effects of interruptions in the supply of infrastructure services on household welfare.CC BY 3.0 IGOACCESS TO ELECTRICITYACCESS TO SAFE DRINKING WATERACCESS TO SERVICESADVERSE EFFECTSADVERSE IMPACTAIR POLLUTIONALTERNATIVE APPROACHAPPROACHAVAILABILITYCONJOINT ANALYSISCONSUMER SURPLUSCONSUMERSCONSUMPTION LEVELSCONTINGENT VALUATIONCONVERSION EFFICIENCYCOST OF ELECTRICITYCOSTS OF ELECTRICITYDEMAND CURVEDEMAND CURVESDEMAND FOR ELECTRICITYDEMAND FUNCTIONDEMAND FUNCTIONSDEVELOPMENT ECONOMICSDRINKING WATER SUPPLYDURABLE GOODSECONOMICS RESEARCHELECTRICITY CONSUMPTIONELECTRICITY DEMANDELECTRICITY SUPPLYELECTRIFICATIONENERGYENERGY SOURCEENERGY SOURCESENERGY USEEQUATIONSEXPENDITUREEXPENDITURESFLEXIBLE FUNCTIONAL FORMSFUELFUEL DEMANDFUEL SUBSTITUTIONFUELSGASGDPGROUND WATERHEATHOUSEHOLDSINCOMEKEROSENEKEROSENE CONSUMPTIONMARGINAL COSTMARGINAL UTILITYMODERN FUELSMUNICIPAL WATERMUNICIPAL WATER SUPPLYPIPED WATERPRICE CHANGEPRICE CHANGESPRICE ELASTICITYPRICE INCREASEPRICE LEVELSPRICE OF ELECTRICITYPRICE OF WATERPRICE VARIATIONPRICE VARIATIONSPRICES OF FUELSPRICING REFORMSPRODUCTION FUNCTIONPRODUCTION FUNCTIONSPROVISION OF WATERPUBLIC WATERPURCHASINGSERVICE DELIVERYSERVICE PROVIDERSSERVICE PROVISIONSERVICE QUALITYSOURCE OF FUELSUBSTITUTESUBSTITUTE GOODSUBSTITUTESSUNK COSTSSURPLUSSUSTAINABLE ENERGYTELECOMMUNICATIONSTEMPERATUREUTILITIESUTILITY FUNCTIONUTILITY FUNCTIONSUTILITY MAXIMIZATIONVERTICAL AXISVOLTAGEWATER CONSUMPTIONWATER QUALITYWATER SOURCEWATER SUPPLYWATER SYSTEMSWELFARE ECONOMICSWELLSWorld Bank10.1596/1813-9450-4217
