Why is poverty so persistent in rural Africa? The design of appropriate strategies to combat persistent poverty depend on its origins. Is poverty something … … all people naturally grow out of in time (unconditional convergence)? … implies laissez-faire /macro focus. … some people grow out of in time (conditional convergence)? … implies need for targeted productivity improvements. … some people can be trapped in perpetually (poverty traps due to multiple equilibria)? … implies need for safety nets and cargo nets.

Moving beyond headcount measures Economic Mobility and Poverty Dynamics Moving beyond headcount measures We want to know the directions and magnitudes of welfare change, not just discrete movements relative to an arbitrary poverty line. Annual average percent change in income, by site and resurveying interval Key point: Short panels may exaggerate economic mobility. Much year-on-year change is random. When we look at longer-term transitions, a lot of stasis – look at structural determinants
Economic Mobility and Poverty Dynamics Raw data suggests convergence … But structural component suggests multiple equilibria Blue (red) dashed lines are structural (stochastic) component of income change
Summary of Findings on Economic Mobility and Poverty Dynamics Considerable persistence of ultra-poverty with low rates of net exit from poverty Poverty deepest where agroecology and markets least favorable (“remote rural areas” or “less favored lands”) Stochastic component of income appears substantial Structural component consistent w/existence of multiple equilibria Data consistent with both the conditional convergence and poverty traps hypotheses..
Why Economic Immobility? Explanation 1: Wealth-differentiated risk mgmt Asset and consumption smoothing among northern Kenya pastoralists … Associated with locally increasing income returns to herd size. Consumption smoothing a luxury enjoyed by the wealthiest third.
Why Economic Immobility? Explanation 2: Locally increasing returns Barriers to entry into higher-return activities - educational attainment and social network rationing (skilled off-farm employment) - labor and liquidity constraints and SRI … expected result is nonlinear asset dynamics, with rapid accumulation beyond key thresholds Marginal return to hh labor supply and rice area, Fianarantsoa
Asset Dynamics with Multiple Equilibria Asset dynamics appear consistent in the Kenya sites with multiple equilibria, but low-level conditional convergence seems to fit the Madagascar sites better. Herd Dynamics Northern Kenya Rangelands Asset Index Dynamics Highland Kenya/Madagascar
Conclusions and Policy Implications Sound policy design and programming requires a clear idea of the causal mechanism behind persistent poverty. No support for the unconditional convergence hypothesis. Conditional convergence apparent at community level in both countries. In Madagascar, the evidence points to geographic poverty traps and the need for exogenous productivity improvements to create path out of poverty. Qual-quant evidence most consistent with poverty traps hypothesis in rural Kenya. Also need multi-dimensional safety nets to protect assets to block pathways into poverty (due to health shocks, natural disasters, etc.). Poverty traps seem to exist due to missing financial markets and (i) excessive risk exposure and/or (ii) significant barriers to entry to remunerative livelihoods.
Misaotra! Asante! Thank you!
