Notes 1.This researchhas been conductedat the WorldBank. The datawere assembledfrom the known internationalsourcessuch as FAO,ILO, the WorldBank, IMF as well as from countrypublications.The results are presentedin terms of empiricaldistributions. The numberof countriesand the periodcoveredin the figuresvary accordingto data availability. 2. Unless indicatedotherwise,all growthrates are computedfrom a semi-logarithmic regressionof the variablein questionon time. 3. The numberof countriesvaries across figuresbecauseof incompletedata sets. 4. In making sucha statement,we note that the verticalaxis in the two figuresis the same and that the units of the horizontalaxis are also the same 5. Based on nationalaccountsdata, convertedto dollars and deflatedby the US GDP deflator. 6. The varianceof the averageland productivityis lower than that of the averagelabor productivity. This is due to biggervariancein the rates of changeof the labor forcethan of land. The pattern of changesin land and labor productivityis discussedby Hayamiand Ruttan (1985). 7. Part of the rent (residualincome)may also be sharedby tenants,dependingon the nature of the contract. 8. The assumptionof equal fertilityrates is made here for purposeof illustration. The migrationrates couldbe estimatedunder the assumptionof differentfertilityrates. 9. The medianin 1990for a larger set of 110 countriesis 9 percent. Figure 15 containsfewer countrieson whichwe have data also for 1950.
