Per capita income versus household-need adjusted income : a cross-country comparison

We use data from the Luxembourg Income Study in order to quantify the economy-wide monetary gains achieved by household-size economies due to within-household sharing of goods by individuals living in multimember households. In most countries out of the twenty countries we examine, we observe a decline in monetary gains achieved by household-size economies over time. This decline is the result of a demographic trend towards smaller-sized household units, rather than a change in the shares of aggregate disposable income earned by household types of different size. -- equivalence scale ; welfare ; demographic change ; Luxembourg Income tudy ; household size economies ; income distribution ; family economics
