Economic philosophersfrom Adam Smithto Hayek andBuchananhave stressed the importanceof rules of law in promoting"good"governmentandthe"wealthof nations".Naturally heyassumethatthe rulesare"good"rules.We will set these indicators in relation to the costs of achievingthem.Wewill, hence,derivesimple performance ndefficiencyindicators or 1990and 2000 for the public sectors of 23 industrialisedOECD countries. Theperformancendex is then also used in a FreeDisposableHull(FDH)analysis,a rarelyused non-parametric roductionfrontiertechniqueto estimate theextent of slack in governmentexpenditures.
Note, however, hat t is notonly public expenditurebut also tax andregu-latorypoliciesthataffect theefficiencyof thepublicsector.Whileexpenditureis also a relatively good proxyof the tax burden,we ignorethe compositionof tax revenueand othercharacteristics f tax systems.1Publicspendingmaybe closely related o regulationbecauselargecivil services,thatoften accom-panylarge public spending,are likely to generatemuchregulationand viceversa.

323Thegreater hepositiveeffect of public expenditureon anyof the selectedsub-indicators, he greaterwill be the envisaged improvement n the PSPindicator.Accordingly,the changes that might occur in the economic andsocial indicatorsmaybe seen as changesin PSP.As a firststep,we define seven sub-indicators f public performance.Thefirst four look at administrative, ducation, health,andpublic infrastructureoutcomes. A good public administration,with a well-functioningjudiciaryanda healthyand well-educatedpopulation,couldbe considereda prerequi-site for a level playingfield with well-functioningmarketsand secureprop-

Theycould be called"pro-cess" or "opportunity"ndicators. We adopt the latter terminology in thefollowing.The three other sub-indicators eflect the "Musgravian"asks for govern-ment.

330In order o computeefficiencyindicators,public spendingwas normalisedacrosscountries,with the averagetakingthe value of one for each of the sixcategories specifiedabove. We focus on averageexpenditureover the 1990s,as we would assume a lagged effect from spendingon performance.Forexample, public spendingon educationover thepreviousdecade,is assumedto affect educationalachievement n 2000.
Computation f theefficiency ndexBefore puttingPSP and expenditure ogether,it is worth stressingthat notall expenditurecategoriesareequally suitable indices for measuring he ef-ficiency with which a certainperformance s achieved. Goods and servicesspendingare a rathercrudeapproximationor what is needed to achieve ad-ministrativeefficiency.Health and educationspendingseem bettermeasuresof the publicsectorinputs n these domains.Noticehowever, hat t is noteasytoaccurately dentifythe effects of publicsectorspendingon outcomes andseparate he impactof spendingfromotherinfluences.Forinstance, t is difficult o assess to what extent does higher ifeexpectancyreflectpublic ntervention atherhanother actorssuch asclimate,dietaryhabits,and so on. The sameargument ould be maderegardingnfantmortality.Onthat ine of reasoning,adversegeographical onditionsmayalsoimpairon thequalityand cost of a countrycommunicationsnfrastructure.Transferssocialpaymentsonly) areprobablysuitableapproximationsorgovernmentspendingto promoteincome equality,andpublic investment slikely to be closely connected with infrastructure uality.8Total spendingmaybe a usefulproxyforgovernment tabilisation ffortsbecauseautomaticstabilisersarelarger n countrieswith "big governments"see, Bouthevillainet al., 2001; Van den Noord,2000). Totalspendingis generallyfinancedbydistortive taxation.It can, hence, be used as a proxy for the efficiency (orinefficiency)of the state in affectingeconomicperformance.Before turning oTable2, which reports he ratio of performanceand ex-penditurendices as so-calledPSEindicators, t is worthwhilestressinga fewcaveats.Publicspendingacross countries s notalways fully comparable venthoughmuchprogresshas been achieved in this regard.Forexample, somecountries' transferpaymentsare taxed, thereby overstatingpublic spendingcompared o countries where such benefits are not taxed. Nevertheless, t isnot possible to systematicallyassess and correct such problems.Moreover,comparingexpenditureratios across countriesimplicitly assumes thatpro-duction costs forpublicservices areproportionateo GDP per capita.Whilethis approximations likely to be quite good for labourintensive services(such as education or administrative fficiency), it is likely to be less so forinfrastructureuality.In the absence of cross-countrydataof differentpublicservice sectorcosts, this is nevertheless he best possible approximation.

333We findsignificantdifferences n PSE acrosscountries.Japan,Switzerland,Australia, he United States andLuxembourg how the best values for over-all efficiency. Looking at country groups, "small"governments post thehighest efficiency amongst ndustrialised ountries.Differencesare consider-able as "small"governmentson averagepost 40% higherscores than"big"governments.9In summary,we find that differences in efficiency are much more pro-nounced than in performanceacross countries,with "small"governmentsclearly outrankinghe others.This illustrates hatthe size of governmentmaybe toolarge nmany ndustrialised ountries,withdecliningmarginalproductsbeingratherprevalent.Butgiventhe non-extremedifferences n performance
as outlinedabove, the incidence of "negative"marginalproductsof publicspendingmaybe more limited.
Measuring Input and Output Efficiency Via an FDH AnalysisTheFDH analysisIn a final step, we use the informationfrom previous sections to measurethe "wastefulness"of public spendingacross countries, i.e., the input andoutputefficiencyof expenditure.To thisend,we applya so-calledFDH anal-ysis, which is a non-parametricechnique hat was firstproposedby Deprins,Simar,andTulkens(1984).10In the FDH frameworkt is possible to ranktheefficiencyof producersby comparing ach individualperformancewith apro-ductionpossibilityfrontier.Along thisproductionpossibilityfrontierone canobserve the highestpossible level of output/outcomeor a given level of in-put.Conversely, t is possibleto determine he lowest level of inputnecessaryto attain a given level of output/outcome.This allows identifyinginefficientproducersboth in termsof inputefficiency and in terms of output/outcomeefficiency.There are a few other studies that apply FDH analysis to assess pub-lic spendingefficiency.Van den Eeckhaut,Tulkens,and Jamar 1993) stud-ied the efficiency of public spendingin Belgian municipalities,and Fakinand Crombrugghe 1997) assessed the efficiency of governmentexpendi-turesas regardssome specific public services in OECD and CentralEuropecountries.Guptaand Verhoeven(2001) use FDH analysis to measure theefficiency of government expenditureon education and health in a setof countries in Africa. Clements (2002) assesses the efficiency of edu-cation spending in the EuropeanUnion. Aubyn (2002) reportsresults ofFDH analysis applied to education and health spending in OECD coun-tries, while Afonso and St. Aubyn (2003) apply both FDH and DEA tothose two sectors. The FDH methodologycan be well illustratedgraphically(Figure3).

Assume fourcountries,A, B, C and D that use a certainamountof publicexpenditures,measuredon the horizontalaxis inmonetaryunits.The countriesare then assumed to achieve a certain evel of public spendingperformance,measuredon the vertical axis.The efficiency of the four countries is obviously different.For instance,countryB uses more input than countryA [X(B) > X(A)], but producesless output[Y(B) < Y(A)]. Therefore,countryB is relativelyinefficient incomparisonwith countryA. On the other hand, countryA is efficient inrelation o countryB, and it is placedon the"production ossibilityfrontier".
This means there are no othercountriesbesides countryA that deliver thesame level of outputwith a lower level of input. Similarly,countries C andD are efficient and are also on the productionpossibility frontier.No othercountry s inefficientcompared o them.11This frameworkallows the calculationof the"production ossibilityfron-tier",and input efficiency and output efficiency scores in order to rank thesample countries in terms of public spending efficiency. These efficiencyscores will be set between 0 and 1, and all the countriesplaced on the"productionpossibility frontier"will be assignedthe maximum score of 1.Note that this approachs likely to underestimatenefficiencies,as the coun-tries on the "production ossibility frontier"are efficientby definition(eventhough they too may have scope for savings). The input efficiency scoreof a given country ndicates how much less inputthis countrycould use toachieve the same level of output. Additionally,the output efficiency scoreof a given countrywould tell how much more outputthe country should

337thanclose to 50%).Theoutputefficiencyscoreimpliesthatwithgivenpublicexpenditures,PSP is 82%(or 18% ess) of what it could be if the EU was ontheproductionpossibilityfrontier andmore f the countrieson theproductionpossibilityfrontieralso havescope forexpenditure avings). By contrast, henon-EUOECDcountriesreportmoreefficientpublic expenditure.An averageinput efficiencyscoreof 0.89 impliesonly roughly 11%"waste".It is also nowpossible to focus on some specific interestingcases, such asSweden. It reportsa PSP indicatorof 1.04, above the averageof the countrysample. High public spendingpushes down the PSE indicatorto a value ofonly0.82, well below theaverage.Theinputefficiencyscore of 0.57 suggeststhat little more thanhalf the currentspendingwouldbe sufficientto achievethe same PSP.The situation s similar n some of theothercountrieswith"biggovernments", amelyFrance,GermanyandItaly,wherepublicexpendituresaccountfor around50%of GDP.Indeed,with the exceptionof Luxembourg,alltwo othercountries ocatedonor near heproductionpossibilityfrontierbe-long to thegroupof "smallgovernment" ountries,with a public expenditureratiobelow the 40% threshold.ConclusionWe developedindicatorsof public sectorperformance PSP) andefficiency(PSE) for 23 industrialisedcountries. For that purposewe used a numberof socio-economic indicatorsas proxies for performance,and total spend-ing and a number of spendingcategories as proxies for resource use. Wefind moderatedifferencesin the PSP indicatorsacross industrialisedcoun-tries. Unsurprisingly, ountries with small public sectors reportthe "best"economicperformance,while countrieswith large public sectors show moreequalincome distribution.
When weighing performanceby the resourcesused to achieve it, thereare importantdifferences across countriesin the resultingPSE indicators.CountrieswithsmallpublicsectorsreportsignificantlyhigherPSEindicatorsthancountries with medium-sized or big public sectors. All these findingssuggestdiminishingmarginalproductsof higherpublicspending.The resultsthatwe get from theproduction-frontier-relatedDHanalysis,which uses the PSP indicators,are also in line with the aforementioned on-clusions. Smallgovernmentsendto show betterresults.Spendingbybiggov-ernmentscouldbe, on average,about 35% lower to attain he same PSP.Thecalculationsalsopointout thatEU 15 countriesshowrelatively ow efficiencywhencomparedwiththeUnited Statesandalso theaverageof theotherOECDcountries n the sample.EU 15 countries areusing 27% morepublic spend-ing than the "mostefficient" countries with similarPSP indicators.Spend-ing for the averageof the other OECDcountries s "only"11%higherthannecessary.

Notes1. Forexample,tax collection may impose significantwelfare andcompliancecosts on tax-payers.2. However,Brennan 2000) and Tanzi(1998) haveargued hatregulationsandtaxexpendi-turescan also become a substituteof public spending,andtherebyarenegativelycorrelatedwith the size of thepublicsector as measuredby the level of public spending.3. One should be aware of the distinction between outputand outcome. The number ofhospital days per 1000peopleis anoutputbutfull recovery rom illness or life expectancyis an outcome. Even thoughwe tryto approximateoutcomes rather hanoutput (e.g. redtape, life expectancy)the distinction s not alwayspossible and we use both terms in aninterchangeableway.4. There are few instances where actual and trendgrowthdeviateby 0.4/0.5% for the 10-year averages.However,when using trendrather hanactualgrowth n the calculationofindices,resultschange very little even for the economicperformancendicator.5. For example, giving alternativeweights to the sub-indicatorsdoes not changemuch theresults in most cases. In the Appendix(TableAl) we presentthe results with alternativeweightingschemes.RankcorrelationsorPSP indicatorswith the testedchanges nweights

339arein the (0.95-0.99) range.This weigthingof the variables s quite straightforwardndeconomicallyintuitive(even thoughit is still somewhatad hoc). It avoids theproblemoflack of economic justificationof a more complex statisticalapproachsuch as principalcomponentanalysisthatmightcome to mind in this context.6. One shouldbear n mindthatdataarenotfully comparable.E.g., some dataarenotavailablefor some countries. Forexamplethe OECDPISA reporton education achievementonlycovers 2000.
7. Proceeds rom the sale of UMTS mobiletelephone icences have been excluded from totalexpenditure ince theywere recordedas a temporarydecline in expenditure.8. Incomedistribution nd stabilisation s also affectedby theprogressivityof the taxsystem,but this effect is verydifficultto assess dueto the lack of comparableanddetailedenoughdata.
9. The PSE indicators are also quite robust to differentweightings as can be seen in theAppendix(TableA2).10. For an overview of the FDH analysis see for instance Tulkens (1993). Anothernon-parametricapproachthat might be used to assess public expenditureefficiency wouldbe Data EnvelopmentAnalysis (DEA). This technique, developed by Charnes,CooperandRhodes(1978), impliesa convexproduction rontier,a hypothesisthat s notrequiredin the FDHapproach.For an overview of non-parametric pproaches ee for instanceSimarand Wilson (2003).11. Guptaand Verhoeven 2001) would call countries such as C and D "independently ffi-cient",andcountryA "not ndependently fficient."12. Figure3 illustrates hatcountryB's input efficiency score is given by X(A)/X(B), whichis 0.5, smaller thanone, since B is the interiorof theproductionpossibilityfrontier.Thisimpliesthat heexcess use of inputsby inefficientcountryB is 50 percent of thenecessaryinputs o achievethe same evel of performance f countryA. CountryB's outputefficiencyscore is Y(B)/Y(A). In thiscase, the loss of outputof countryB relative o the mostefficientcountryturnsout to be also 50 percent (since forcountryB one can calculateY(B)/Y(A)= 5/10 = 0.5). Theproductionpossibilityfrontier or theexample nFigure3 is asfollows:
0, X < 10010, 100< X < X(C)(X)= (C), X(C) < X < X(D)Y(D), X > X(D)
13. Note that the termproductionpossibility frontieris somewhatmisleading, as the true"frontier"s unknown.Onemustalso be awareof the scalingwhen interpretinghe chart.A doubling n PSP is notnecessarilya doublingof welfare or utility.
AppendixIn order to assess the sensitivity of the results for PSP and PSE, we usedalternativeweightingschemes. WecomputedPSP andPSE indicators hatcangive moreweight to, interalia, opportunity, quality,stabilityand economicperformancesub-indicators.One could arguethat these indicatorsemulatepeoplewithdifferentntensitiesof preferences.Theresults,presentednTableAl and n TableA2, confirm hat heconclusionspresentedn the maintextaregenerallynot changed.Rank correlationswith the testedchangesin weightsare in the (0.95 0.99) rangefor PSPindicatorsandin the(0.96 0.99) rangeforPSE indicators.
