in marginal costs, stemming, for instance, from differences in product attributes. We find
that the pink gap is often negative; men’s products command higher per-product prices in
six of nine categories that we study and higher unit prices in three of nine categories. We
then estimate the pink tax via an apples-to-apples comparison of products manufactured
by the same firm and comprising the same leading ingredients. Controlling for attributes
shrinks price differences in all but one category. Further, men’s products are more expensive
in four of six categories when we control for ingredients. Taken together, our findings do not
support the existence of a systematic price premium for women’s products, but our results do
reveal that gender segmentation in personal care is pervasive and operates through product
differentiation. A back-of-the-envelope calculation implies that the average household would
save less than 1% by switching to substantially similar products targeted to a different gender.
The potential savings are much larger – on the order of 20% – if a household were willing
instead to substitute to products with different gender-targeting and different formulations.

However, a revealed preference argument suggests that such switching would lower consumer
welfare.
The implications of our findings for current and proposed legislation are several. First,
our finding that women’s personal care products are not systematically more expensive calls
into question the role of government intervention to reduce the pink tax. We acknowledge
that our findings speak to average price differences, which may mask instances of a particular
retail outlet pricing in a way precluded by the Pink Tax Repeal Act. As an example, if one
store sets a 5% higher price for the men’s version of a product and a neighboring store sets
a 5% higher price for the women’s version, we would detect no gender price gap, but the
Pink Tax Repeal Act would require that both retailers change their pricing policy or alter
their product assortments. However, our analysis reveals that most women’s products do not
have a men’s analog sold in the same retail store, limiting the scope for such adjustments.
Even in cases where a retailer does sell a women’s variant at a higher price than its men’s
analogue, the Pink Tax Repeal Act might induce the retailer to drop the men’s variant, de

To approximate household savings, we first compute the dollar spending, average price, and total volume (mea-
sured in ounces or counts) of purchases made by each Homescan household for each product category/gender com-
bination analyzed in Table 4. Next, for each household/category/gender, we construct the counterfactual price a
household would pay if they were willing to switch to the cheaper gender within each product category. We do this
by adjusting the household’s price paid for the more expensive gender by the estimated price gaps reported in Table 4.
When estimating savings from switching to a comparable formulation, we use the estimates in column (5), and when
estimating savings when switching across formulations, we use the estimates in column (2). We then compute the
household’s counterfactual personal care spending by multiplying the counterfactual prices by the observed purchase
volumes and summing across categories. When estimating savings from switching to a comparable formulation, we
also need to account for whether a household’s purchases actually have a formulaic analog that is targeted to the
other gender. We do so by multiplying each household’s category-level purchase volumes by the fraction of each
gender’s unit sales that have a comparable formulation on the shelf in the average store (column (6) of Table 5). The
estimated savings from switching within formulation across gender (0.9%) are much lower than the potential savings
from switching across formulations (20%) both because most purchases don’t have a comparable formulation offered
to the other gender in the same store, and because the price gap within a formulation is substantially smaller than
the price gap unconditional on formulation.
