If countries struggle to transition from growth strategies that are effective at low income levels to growth strategies that are effective at high income levels, they may stagnate at some middle income level; this phenomenon can be thought of as a "middle income trap." This paper does not find evidence for (unusual) stagnation at any particular middle income level. However, it does find evidence that the determinants of growth at low and high income levels differ. These findings suggest a mixed conclusion: middle-income countries may need to change growth strategies to transition smoothly to high-income growth strategies, but this can be done smoothly and does not imply the existence of a middle income trap.application/pdftext/plainCC BY 3.0 IGOhttp://creativecommons.org/licenses/by/3.0/igo/AGRICULTUREANNUAL CHANGEANNUAL GROWTHANNUAL INFLATIONAVERAGE ANNUALAVERAGE CHANGEAVERAGE GROWTHBASE YEARCAPITAL ACCUMULATIONCAPITAL STOCKCAPITAL STOCKSCAPITAL-LABOR RATIOCIVIL WARCONDITIONAL CONVERGENCECOUNTRY CHARACTERISTICSCOUNTRY GROWTH PERFORMANCECOUNTRY LEVELCROSS-COUNTRY INCOMEDATA SETDEBTDEMOCRACYDEMOGRAPHICDEPENDENT VARIABLEDEVELOPING COUNTRIESDEVELOPMENT POLICYDIVIDENDECONOMIC ACTIVITYECONOMIC GROWTHECONOMIC REFORMSECONOMIC REVIEWECONOMIC STRUCTUREEXPORTSEXTERNAL DEBTEXTERNAL SHOCKSFACTOR SHARESFERTILITY RATEFINANCIAL DEVELOPMENTFUTURE GROWTHGDPGDP PER CAPITAGINI COEFFICIENTGINI COEFFICIENTSGOVERNANCE INDICATORSGROWTH ACCELERATIONGROWTH DETERMINANTSGROWTH EFFECTGROWTH LITERATUREGROWTH PERFORMANCEGROWTH POLICIESGROWTH RATEGROWTH RATESGROWTH REGRESSIONSHIGH GROWTHHIGH INCOMEHIGH INCOME COUNTRIESHIGH INCOME COUNTRYHIGH INFLATIONHOUSEHOLD SURVEYSHUMAN CAPITALINCOMEINCOME COUNTRIESINCOME DIFFERENCESINCOME DISTRIBUTIONINCOME DYNAMICSINCOME GROUPINCOME GROUPSINCOME GROWTHINCOME LEVELINCOME LEVELSINDUSTRIALIZATIONINEQUALITYINEQUALITY DATAINFLATIONINSTITUTIONAL CONSTRAINTSINTERNATIONAL COMPARISONSINVENTORYLAGGED GROWTHLOW INCOMEMACROECONOMIC CONDITIONSMACROECONOMIC MANAGEMENTMACROECONOMICSMEDIAN AVERAGEMIDDLE INCOMEMIDDLE INCOME COUNTRIESMIDDLE INCOME COUNTRYMIDDLE-INCOME COUNTRIESMONETARY ECONOMICSNEGATIVE COEFFICIENTOIL EXPORTERSOUTPUTPATENTSPER CAPITA INCOMEPER CAPITA INCOME LEVELSPER CAPITA INCOMESPOLICY DISCUSSIONSPOLICY RESEARCHPOLITICAL ECONOMYPOLITICAL REGIMEPOOR COUNTRIESPOSITIVE CORRELATIONPOSITIVE EFFECTPRIMARY EDUCATIONPRO-GROWTH POLICIESPRODUCTION FUNCTIONRAPID GROWTHRATE OF INVESTMENTREAL EXCHANGE RATEREAL EXCHANGE RATESREGIME CHANGESREGRESSION ANALYSISREGRESSION RESULTSRELATIVE INCOMESERIAL CORRELATIONTOTAL FACTOR PRODUCTIVITYUNDERVALUATIONWAGEWORLD DEVELOPMENT INDICATORSWORLD ECONOMY
