It is conventional wisdom that richer countries have a higher price level than poorer countries. This paper provides evidence that the price-income relationship is non-linear and that it turns negative, or at best flat, in low income countries. The result is robust along both cross-section and time-series dimensions. Additional robustness checks show that biases in PPP estimation and measurement error in low-income countries do not drive the result.
