We test whether young adults who co-reside with their parents derive influence over household-level expenditure by earning income. We propose a new variant of the Engel curve consistent with the Quadratic Almost Ideal Demand System, which allows a simple test of income pooling. Our tests suggest that young adults and parents mostly pool their income - pooling is not rejected for 8 out of 12 expenditure categories. We are more likely to reject income pooling between young adults and their parents in those expenditure categories where the model fit is highest, so our results may be interpreted as an upper bound on income pooling. We also apply our tests to income pooling between husbands and wives and find that pooling holds for 9 out of 12 expenditure categories. We find the opposite relationship with fit - expenditure categories where fit is poor are those where we are most likely to reject income pooling.
