We analyse the relationship between income volatility and inequality and the conditional role played by aid and remittances. Using a panel of 142 countries for the period 1973–2012, we confirm a well-established finding among the literature that income volatility has an adverse impact on inequality, and that the poorest people are the most exposed to these fluctuations. However, while aid and remittances do not seem to have a clear direct impact on inequality, we uncover robust evidence that suggests that aid helps dampen the negative effects of volatility on the distribution of income, while remittances do not.

波动加剧了不平等。可以帮助和汇款吗？

我们分析了收入波动与不平等之间的关系以及援助和汇款发挥的条件作用。我们在1973年至2012年期间由142个国家组成的小组中，我们确认了文献中一项公认的发现，即收入波动对不平等产生不利影响，最贫穷的人群最容易受到这些波动的影响。然而，尽管援助和汇款似乎对不平等没有明显的直接影响，但我们发现有力的证据表明，援助有助于减轻波动性对收入分配的负面影响，而汇款却没有。
