Poverty as a self-perpetuating cycle the cycle is intended to correspond with households’ lived experience different households will differ in its applicability and its content the outcome “variable” is perpetuation of the cycle the central concept is reserve capacity when this reaches zero, cycle interruption occurs food insecurity: variability in reserve capacity the cycle’s causal processes occur over time attention is needed to generalisability of: overall structure, component variables & links, parameter estimates – and, reasons for the latters’ variation between households and between locations

Thank you!

Poverty as a self-perpetuating cycle the cycle shows the main interrelations: BREADTH of poverty outcome “variable” is perpetuation of the cycle the central concept is reserve capacity, corresponding to SEVERITY/DEPTH of poverty when this reaches zero, cycle interruption occurs cf. food insecurity: variability in reserve capacity the cycle’s causal processes occur over time – this has implications for DURATION of poverty – it requires longitudinal assessment the cycle corresponds to households’ lived experience attention is needed to generalisability of: overall structure, component variables & links, parameter estimates – and, reasons for the latters’ variation “deterministic” links include: dietary intake & anthropometry; bed nets & malaria probabilistic links include the risk of child & adult mortality representative population; theoretical sampling
