This paper develops a new approach for dealing with the under-reporting of wealth in house- hold survey data (differential nonresponse). The current practice among researchers relying on household wealth survey data is one out of three approaches. First, simply ignore the problem. Second, fit a...

Underreporting and undersampling biases in top tail wealth, although widely acknowledged, have not been statistically quantified so far, essentially because they are not readily observable. Here we exploit the functional form of power law-like regimes in top tail wealth to derive analytical...

This paper combines national accounts, survey and tax data to provide consistent series on income distribution in Poland over the 1983-2015 period. We find that official survey-based inequality estimates substantially underestimate the rise of inequality since the end of Communism. The top 10%...
