The development accounting literature tries to account for cross-country output per worker differences by taking stock of inputs per worker. The data employed are often measured without great precision, however, making comparisons difficult. This column presents a new, internationally comparable dataset of average hours worked per adult across the world income distribution. Adults in poor countries are found to work a lot more and with lower productivity than those in rich countries. The findings suggest that those from poorer countries are not only ‘consumption poor’, but also ‘leisure poor’.
