The cross-country evidence suggests no direct relationship. The positive and significant coefficient on private investment appears to be driven by Botswana's presence in the sample. Allowing for the endogeneity of private investment, controlling for policy, and positing a nonlinear relationship make no difference to the conclusion. Higher investment in Africa would not by itself produce faster GDP growth. Africa's low investment and growth rates seem to be symptoms of underlying factors. To investigate those factors and to correct for some of the problems with cross-country analysis, the authors undertook a case study of manufacturing investment in Tanzania. They tried to identify why output per worker declined while capital per worker increased. Some of the usual suspects--such as shifts from high- to low-productivity subsectors, the presence of state-owned enterprises, or poor polices--did not play a significant role in this decline. Instead, low capacity utilization (possibly the by-product of poor policies) and constraints on absorptive capacity for skill acquisition seem to be critical factors. If Tanzania is not atypical, the low productivity of investment in Africa was the result of a combination of factors that occurred simultaneously, not any single factor. What does this tell us? First, we should be more careful about calling for an investment boom so that Africa can resume growth. Unless some or all of the underlying problems are addressed, the results may be disappointing. We should also be more circumspect about Africa's low savings rate; it may be low because returns to investment were so low. The relatively high level of capital flight from Africa may have been a level rational response to the lack of investment oportunities at home. Second, there is probably no single key to unlocking investment and GDP growth in Africa. All of the factors contributing to low productivity should be addressed simultaneously.en-USCC BY 3.0 IGOADJUSTMENT PROGRAMSAGGREGATE PRODUCTION FUNCTIONAGRICULTUREAVERAGE GROWTHAVERAGE GROWTH RATEBLACK MARKETBLACK MARKET PREMIUMBUDGET DEFICITSCAPITAL ACCUMULATIONCAPITAL FLIGHTCAPITAL GAINSCAPITAL GOODSCAPITAL INVESTMENTCAPITAL STOCKCAPITAL STOCK GROWTHCAPITAL- LABORCAPITAL- LABOR RATIOSCAPITAL- OUTPUT RATIOCAPITAL-LABORCAPITAL-LABOR RATIOCAPITAL-LABOR RATIOSCOMPETITIVE PRESSURESCONVENTIONAL ANALYSISCOUNTRY DATACOUNTRY GROWTHCOUNTRY REGRESSIONSCOUNTRY VARIATIONCROSS COUNTRYCROSS- COUNTRY ANALYSISCROSS-COUNTRY ANALYSISCROSS-COUNTRY GROWTH REGRESSIONSCROSS-COUNTRY REGRESSIONSCROSS-COUNTRY VARIATIONCROWDING OUTDATA SETSDEBTDEPENDENT VARIABLEDEVELOPING COUNTRIESDEVELOPMENT ECONOMICSDEVELOPMENT RESEARCHDOMESTIC SAVINGECONOMIC GROWTHECONOMIC LITERATUREECONOMIC PERFORMANCEECONOMIC RESEARCHEFFECTIVE USEEMPLOYMENTENDOGENOUS GROWTHEXTERNALITIESFACTOR ACCUMULATIONFINANCIAL INSTITUTIONSFINANCIAL LIBERALIZATIONFOREIGN EXCHANGEGDPGENERAL PRODUCTION FUNCTIONGROWTH ACCOUNTINGGROWTH DEBATEGROWTH MODELGROWTH MODELSGROWTH PERFORMANCEGROWTH PROCESSGROWTH RATEGROWTH RATESGROWTH REGRESSIONGROWTH REGRESSIONSGROWTH RELATIONSHIPGROWTH THEORYGROWTH TRAGEDYHIGH GROWTHHUMAN CAPITALIMPORTED INPUTSINCOMEINCOME DIFFERENCESINDIVIDUAL COUNTRIESINEFFICIENCYINFRASTRUCTURE INVESTMENTINVESTMENT POLICIESINVESTMENT RATEINVESTMENT RATESLABOR FORCELABOR PRODUCTIVITYLEVEL OF CAPITALLIQUIDITYLOCAL INDUSTRYLONG-RUN GROWTHLOW INFLATIONMACROECONOMIC POLICIESMACROECONOMIC POLICYMACROECONOMICSMARKET DISTORTIONSMARKET FORCESMEMBER COUNTRIESMICRO DATAMONETARY ECONOMICSNATIONAL ACCOUNTSNOMINAL INTEREST RATEOUTPUT GROWTHOUTPUT PER CAPITAOUTPUT RATIOPER CAPITA GROWTHPER CAPITA INCOMEPOLICY DEBATEPOLICY RESEARCHPOLICY VARIABLESPOOR COUNTRIESPOOR POLICIESPOPULATION GROWTHPRIVATE INVESTMENTPRIVATE SECTORPRODUCT MARKETSPRODUCTION FUNCTIONPRODUCTION FUNCTIONSPRODUCTIVITYPRODUCTIVITY GROWTHPRODUCTIVITY OF CAPITALPUBLIC EXPENDITUREPUBLIC EXPENDITURESPUBLIC INFRASTRUCTUREPUBLIC INVESTMENTPUBLIC POLICIESPUBLIC SECTORPUBLIC SPENDINGSAVINGSSIGNIFICANT EFFECTSIGNIFICANT IMPACTSOCIAL CAPITALSTANDARD ERRORSSTATE ENTERPRISESSTATE-OWNED ENTERPRISESSURPLUS LABORTECHNICAL CHANGETECHNICAL PROGRESSTECHNOLOGICAL KNOWLEDGETFPTOTAL FACTOR PRODUCTIVITYUNDERLYING PROBLEMSVALUE ADDEDWAGESWEALTHWORLD MARKETIs Investment in Africa Too Low or Too High?
