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...

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 real incomes. The bias is substantial and systematic: the poorer is a country, the...

We use the shifts in Engel curves calculated from household surveys to estimate CPI biases in Argentina between 1985 and 2005. We find that real earning levels increased during this period between 4.3 and 5.7% faster per year than previously estimated. More surprisingly, relative to conventional...

Price-adjusted data on national incomes applied in cross-country comparisons are measured with bias. By studying micro data, this paper finds that the bias is systematic: the poorer a country is, the more its income tends to be overestimated. Consequently, international income inequalities are...

The inequality growth during the last quarter century is explained as caused by a decreasing labor-labor exchange rate, i.e. devaluation of one's labor in exchange for other's labor embodied in the commodities affordable for one's earnings. We show that the productivity growth allows employers...

The current trends in the capital/labor split and the impacts thereof on the growth of inequality are one of the main concerns of national governments, European Commission and international organizations like UN, ILO, IMF, OECD and WB. These trends are usually studied at the macro level of...

Personal income tax is attracting more attention from the Vietnamese government, which has been looking for a way to reinforce its budget revenue. Although this tax plays an increasing role, representing 7.3 per cent of the revenue expected in 2018, this figure is still small, suggesting an...
