摘要	Poverty Dynamics Analysis uses household panel data to study how poverty changes over time for the same people, distinguishing those who are persistently poor from those who move in and out of poverty. Building on the work of Jyotsna Jalan and Martin Ravallion (1998) and the comparative synthesis of Bob Baulch and John Hoddinott (2000), it reframes poverty from a static headcount into a study of entries, exits, and spells. Its central output is a separation of total poverty into a chronic component, attributable to persistently low living standards, and a transient component, attributable to fluctuations around the poverty line over time.	The Multidimensional Poverty Index applies the Alkire-Foster method, introduced by Sabina Alkire and James Foster in 2011, to measure poverty as the joint deprivation of individuals across several dimensions such as health, education, and living standards. Its signature is a dual-cutoff identification: a person is deprived in an indicator if they fall below that indicator's cutoff, and they are counted as multidimensionally poor only if their weighted count of deprivations crosses a cross-dimensional cutoff k. The headline measure is the adjusted headcount ratio M0 = H times A, the product of the share of people who are poor (incidence) and the average breadth of their deprivations (intensity).
