We show that measures of inequality of opportunity (IOP) fully consistent with Roemer (1998)'s IOP theory can be straightforwardly estimated by adopting a machine learning approach, and apply our novel method to analyse the development of IOP in Germany during the last three decades. Hereby, we...

Income inequality in Germany has been continuously increasing during the past 20 years. In general, this is understood as an increase in inequality of wages due to changes in bargaining power of employees. However, the role of changing household structure is widely neglected. Societal trends...

Deploying data from the German Socio-Economic Panel (GSOEP) we analyze the variability of individual earnings and equivalent household income. Permanent and transitory variances of male income over the period 1984-2008 are estimated for Old German Laender in order to determine their importance...

We analyze the distributive justice of the combined burden of taxes, social security contributions and public transfers on employee households. In order to investigate whether the treatment of families by the aggregate tax-benefit system can be regarded as "fair" we compare the equivalent...

We show how normative standpoints determine optimal taxation of wealth. Since wealth is not equal to capital, we find very different welfare implications of land rent-, bequest- and capital taxation. It is mainly land rents that should be taxed. We develop an overlapping generations model with...

We examine how trade openness influences income inequality within countries. The sample includes 139 countries over the period 1970-2014. We employ predicted openness as instrument to deal with the endogeneity of trade openness. The effect of trade openness on income inequality differs across...

Green tax reform is unpopular because, typically, the poor are hurt most by the higher prices of carbon-intensive commodities. If revenues from a carbon tax are recycled, it may be feasible to gain popular support for green tax reform. To investigate this, we estimate an EASI demand system from...

Every month, the ifo Business Survey (IBS) asks a representative set of 9000 German firms about their current and expected economic conditions. Thus, the micro data of the IBS are ideally suited to study various aspects of firm behavior. However, methodological heterogeneities between different...

Women are less financially literate than men. It is unclear whether this gap reflects a lack of knowledge or, rather, a lack of confidence. Our survey experiment shows that women tend to disproportionately respond “do not know” to questions measuring financial knowledge, but when this...

The monthly ifo Business Survey is the basis for numerous economic indicators, such as the ifo Business Climate Index Germany. Moreover, the anonymized micro data can be used for a wide range of research projects. In order to obtain robust results, the panel of survey participants must be large...
