According to the well‐known concept of consumption smoothing, the volatility of consumption is low even when income is volatile; this is confirmed by data from G7 countries. Surprisingly, however, consumption volatility in many low‐income countries is nontrivially higher than income volatility. Here I examine what causes high consumption volatility in low‐income countries. In general, volatile consumption makes consumers worse off. Therefore, understanding the causes of high consumption volatility can contribute to improving welfare in low‐income countries by suggesting measures to assist in the stabilization of consumption. Unlike much previous research, I focus on international factors when explaining high consumption volatility. The results suggest that external shocks, which are far more volatile in low‐income countries than in industrialized countries, strongly swing consumption. By capturing these mechanisms, the model I use successfully accounts for consumption volatility's differences between the sample low‐income country and sample industrialized country.
