The Big Mac Index was introduced to (semi-humorously) test the theory of purchasing power parity and measure the disparity in currency values. Instead, in this paper, we consider this index to find out the per capita real-income disparity across 54 countries. We find that the per capita...

Using the Big Mac Index, we offer a simple approach to study the real income inequality. We provide a multidimensional real income inequality analysis by exploring the Coefficient of Variation and the Big Mac Affordability of households across all income deciles of 28 countries for years 2000 to...

Using the Big Mac Index and focusing on the deciles of the income distribution, we produce a descriptive study of real income inequality from households in 29 countries and for period 2000 to 2013. Using daily Big Mac Affordability (BMA), we rank and show differences in the living standards and...

Purchasing power adjusted incomes applied in cross-country comparisons are measured with bias. In this paper, we estimate the purchasing power parity (PPP) bias in Penn World Table incomes and provide corrected incomes. The bias is substantial and systematic: the poorer a country, the more its...

Regional differences in prices levels are substantial in many countries, but little is known about how important they are for income inequality and relative poverty. To bridge this gap, we provide new evidence on the basis of the best available data and a novel two-step approach. First, we...
