The effect on aggregate poverty of mobility between permanent and temporary poverty is found to be unambiguous only in the case of the headcount poverty measure. Simulations are used to investigate the relationship between poverty and mobility. The effects of two different types of mobility (random proportio nal income changes and a systematic regression towards or away from the median) are isolated
