1. Schoolinghasexpanded,reducingthesupplyofunskilledlabor,especiallyinruralareas.

2. Therehasalsobeenadeclineinfemalelabor-forceparticipationrates.

Cross-countrycomparisonscanbedeceptive

• Pastresearchhasreliedoncross-countrycomparisons– Singlecross-sections(suchasinthemanytestsoftheKuznets

hypothesis)– Sometimesusingpaneldata,thoughthetypicallyshorttime-

• However,developmentovertimewithincountriesneednotaccordwiththecross-countrypatterns.

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.
