• ThathopewaslargelyshatteredbytheslowpaceofpovertyreductionintheperiodfromIndependenceuntilthe1980s.

• Why? Someobserverspointedtotheslowpaceoflaborabsorptionfromagricultureassociatedwiththemoreinward-lookingandcapital-intensivedevelopmentpathofthisperiod.

TighteningofIndia’scasuallabormarkets

• Tighteningofruralcasuallabormarkets.– Risingrealwagerates.– Narrowingoftheurban-ruralwagegap(Hnatkovska andLahiri,

2013).• Why?

1. Schoolinghasexpanded,reducingthesupplyofunskilledlabor,especiallyinruralareas.

2. Therehasalsobeenadeclineinfemalelabor-forceparticipationrates.

• ConstructionboomacrossIndia,especiallyin(ruralandurban)infrastructure,whichhadbeenneglectedforalongperiod.

• Risinglabordemandfromconstruction=>higherwagesofunskilledlaborrelativetoskilledlabor within ruralareas,aswellasrisingruralrelativetourbanwages(formaleworkers).

• Unclearhowpermanentthischangewillprovetobe.– Itmaybeconjecturedthat(likeChina)IndiahasreacheditsLewis

Cross-countrycomparisonscanbedeceptive

• Pastresearchhasreliedoncross-countrycomparisons– Singlecross-sections(suchasinthemanytestsoftheKuznets

hypothesis)– Sometimesusingpaneldata,thoughthetypicallyshorttime-

serieshasmeantthatthecross-countryvariabilityisdominant.

• However,developmentovertimewithincountriesneednotaccordwiththecross-countrypatterns.

• Desirabletohaveareasonablylongtimeseriesofsurveys;ashortseriescanbedeceptiveforinferringatrend.

Whyhaspovertyfallensomuchfasterinsomestatesthanothers?

• Higher average farm yields, higher public spending on development, higher non-farm output and lower inflationwere all poverty reducing in India

• Agricultural growth, development spending and inflation had similar effects across states

• However, the response of poverty to non-farm outputgrowth in India varied significantly between states.

• The states with initially higher levels of human development saw greater poverty impacts from non-farm growth. Better infrastructure also helped.

Initial conditions matter to the impact of growth on poverty

• Low farm productivity, low rural living standards relative to urban areas and poor basic education all inhibited the prospects of the poor participating in growth of India’s non-farm sector.

• Rural and human resource development appear to be strongly synergistic with poverty reduction through an expanding non-farm economy.
