  1. Pro-Poor Growth

  2. Cross-country evidence: high correlation b/w growth & poverty • Dollar & Kraay (2000): • - Growth is good for the poor irrespective of the • nature of growth. • More microeconomic approach is required rather than • cross-country regression method.

  3. Three Scenarios 1: Trickle-down Growth - Economic growth reduces poverty but increases inequality. 2: Pro-poor Growth - Economic growth reduces poverty but the poor receive proportionally greater benefits. Growth reduces poverty but inequality also reduces. 3: Immiserizing Growth (Bhagwati) - Economic growth increases poverty.

  4. What is Pro-Poor growth ? • How can we measure its degree ? • Poverty reduction depends on: • (i) growth rate • (ii) how the benefits of growth are • distributed to the poor • -Pro-poor growth index takes into account the two.

  5. Poverty Growth Curve L(p) : % share of income (exp) of the bottom p % of pop. : mean income of the society : generalized Lorenz curve

  6. Atkinson’s Theorem (for all p) (for all poverty line and entire class of poverty)

  7. -Given and -Taking log and first difference in both sides:

  8. If

  9. Lemma 1: If for all p, then poverty reduces unambiguously. Lemma 2: Pro-poor Trickle-down Immiserizing & g(p) < 0

  11. Ravallion’s growth incidence curve: How is it different from our poverty growth curve? x(p) : per capita income (exp) at the pth percentile r(p): Growth rate of the per capita income at the pth percentile r(p) > , then growth is pro-poor.

  12. -Ravallion’s GIC is based on the first order dominance, whereas our PGC is based on the second order dominance. -Since r(p) is the growth rate of income at the pth percentile, its estimation from the unit record data will be subject to more errors because the data are discrete. -Our dominance requirement is based on the estimation of the growth rates of the mean income up to the pth percentile. Thus it is subject to less errors. Our approach only requires the decile shares and the mean income.

  13. Poverty equivalent growth rate (PEGR) Growth elasticity of poverty (Kakwani, 1993) = where r(p) = dln(x(p)), the growth rate of income at pth %

  14. Using , = total poverty elasticity = growth elasticity of poverty when inequality does not change = inequality effect of poverty reduction

  15. Pro-Poor Index: Kakwani & Pernia (2000) > 1: Pro-poor < 1: Trickle-down 0 < < 1: Immiserizing

  16. Poverty Equivalent Growth Rate is the growth rate that would result in the same level of poverty reduction as the actual growth rate if the growth process was not accompanied by any change in inequality. and , is the poverty equivalent growth rate (PEGR)

  17. : Pro-poor growth : Trickle-down : Immiserizing and

  18. - Foster-Greer-Thorbecke - Poverty Gap Ratio - Watts Measure (Ravallion)

  19. Estimation of PEGR is growth elasticity of poverty and should satisfy where

  20. -Based on Kakwani’s (2000) poverty decomposition: will be always negative. < 0: growth is pro-poor > 0 & < 0: growth is trickle down > 0 & > 0: growth is immiserizing

  21. Where Do We Go From Here ? -The analysis presented here is ex-post attempting to answer questions such as: -Is economic growth pro-poor? And if so, what is its degree? -Other important questions are: -Why is growth pro-poor in one period and not in another period? -What are the factors that affect pro-poorness of growth? -Is migration from rural to urban areas pro-poor? -Has the pro-poorness of growth increased or decreased because of differential growth rates in rural and urban areas? -Does the improvement in the educational levels lead to more or less pro-poor growth? -Has the increase or decrease in inequality within urban and rural areas contributed to pro-poorness of growth? -Answer to these and many related questions can give us an insight on policies to achieve pro-poor growth .

  22. -We can answer these and related questions by utilizing the poverty decomposition proposed in the paper. -Son (2003) “A New Decomposition” Journal of Economic Inequality, Vol.1, pp 1-7 -What are the policies that make growth pro-poor? -How can we measure whether or not a given government policy is pro-poor? How can we improve these policies so that we achieve a maximum reduction in poverty with fixed resources? -Which of the government services pro-poor and which are not? -Our future research will focus on these issues.
