Many consumer products—such as deodorants, shaving products, and hair care products—are differentiated to appeal specifically to men or women through differences in packaging, scent, or other product characteristics (see fig. 1). These differences related to gender can affect manufacturing and marketing costs that may contribute to price differences in products targeted to different genders. However, firms may also charge consumers different prices for the same (or very similar) goods and services even when there are no differences in costs to produce. To maximize profits, firms use a variety of techniques to charge prices close to the highest price different consumers are willing to pay. Firms may attempt to get segments of the consumer market to pay a higher price than another segment by slightly altering or differentiating the product. Based on the differentiated products, consumers self-select into different groups according to their preferences and what they are willing to pay. For example, some consumer goods have different versions of what is essentially the same product—except for differences in packaging or features, such as scent—with one version intended for women and another version intended for men. The two products may be priced differently because the firm expects that one gender will be willing to pay more for the product than the other based on preference for certain product attributes. Firms may also use some group characteristic, such as age or gender, to charge different prices because some groups may have differences in willingness or ability to pay. For example, a firm may offer discounted movie tickets to students or seniors, as they may have less disposable income. For the seller the cost of providing the movie is the same for any customer, but the seller is able to maximize its profits by offering tickets to different groups of customers at different prices. A firm’s ability to differentiate prices depends on multiple factors, such as the firm’s market power (so that competitors cannot put downward pressure on prices to eliminate the price differences), the presence of consumer segments with different demands and willingness to pay, and control over the sale of its product so it cannot be easily resold to exploit price differences. In addition, the extent to which consumers pay different prices for the same or similar goods can depend on other factors, such as consumers’: willingness to purchase an item they believe may be priced higher for ability to compare prices and product characteristics and choose a product based on its characteristics rather than its price, choices about whether to purchase a more expensive version of the product (e.g., a branded item versus a cheaper store brand), choices about where to purchase the item (i.e., when different retailers sell the same item at different prices), and use of coupons or promotions. No federal law expressly prohibits businesses from charging different prices for the same or similar consumer goods and services targeted to men and women. However, consumer protection laws do prohibit sex discrimination in credit and real estate transactions. Specifically, the Equal Credit Opportunity Act (ECOA) prohibits creditors from discriminating against credit applicants based on sex or certain other characteristics and the Fair Housing Act (FHA) prohibits discrimination in the housing market on the basis of sex or certain other characteristics. ECOA and FHA (collectively known as the fair lending laws) prohibit lenders from, among other things, refusing to extend credit or using different standards in determining to extend credit based on sex. Credit, such as a credit card account or mortgage loan, is generally made available and priced based on a number of risk factors, including credit score, income, and employment history. A borrower with a lower credit score is likely to pay a higher interest rate on a loan, reflecting the greater risk to the lender that the borrower could default on the loan. In addition to the interest rate, borrowing costs for consumers can also include fees and other costs charged by lenders or brokers. However, there may be differences in average outcomes for men and women—such as for availability of credit or interest rates—if there are differences related to gender in the factors that determine creditworthiness, such as income. BCFP, FTC, the federal prudential regulators, and DOJ have the authority to investigate alleged violations of ECOA and are primarily responsible for enforcing the act’s requirements, while HUD and DOJ share responsibility for enforcing the provisions of FHA. Further, BCFP and the prudential regulators oversee regulated entities for compliance with ECOA by, among other things, collecting complaints from the public and through routine inspections of the financial institutions they oversee. HUD and DOJ have the authority to bring enforcement actions for alleged violations of FHA. In 5 out of 10 product categories we analyzed, personal care products targeted to women sold at higher average prices than those targeted to men after controlling for certain observable factors. For 2 of the 10 product categories, men’s versions sold at higher average prices. While the factors we controlled for likely proxy for various costs and consumer preferences, we could not fully observe all underlying differences in costs and demand for products targeted to different genders. As a result, we could not determine the extent to which the gender-based price differences we observed may be attributed to gender bias as opposed to other factors. Women’s versions of personal care products sold at a statistically significant higher average price than men’s versions for 5 of the 10 personal care product categories we analyzed—using two different price measures and after controlling for observable factors that could affect price, such as brands, product size or quantity, promotional expenses (see table 1) and other product-specific attributes (e.g., scent, special claims, form). Because women’s and men’s versions of the same product were frequently sold in different sizes, we compared prices using two price measures: average item price and average price per ounce or count of product. For 2 of the 10 product categories—shaving gel and nondisposable razors—men’s versions sold at a statistically significant higher price using both price measures. For one category (razor blades), women’s versions sold at a statistically significant higher average price per count, but there was no gender price difference using average item prices. Additionally, for two product categories—disposable razors and mass-market perfumes—there were no statistically significant price differences between men’s and women’s products using either price measure. In addition to this analysis of retail price scanner data, we also manually collected advertised online prices for a limited selection of personal care products targeted to women and men from several online retailers. Some price comparisons of advertised online prices for men’s and women’s versions of a product were similar to comparisons of average prices paid based on the Nielsen retail price scanner data. For example, for three pairs of comparable underarm deodorants, the women’s deodorant was listed at a higher price per ounce on average than the men’s deodorant (see app. II). In addition, for one pair of shaving gel products we analyzed, the men’s shaving gel was listed at a higher price per ounce on average. However, for both pairs of nondisposable razors we analyzed, the women’s razors were listed at a higher average price per count than the men’s razors. This contrasted with the Nielsen data showing that men’s nondisposable razors sold at higher prices on average than women’s. An important limitation of our analysis of these advertised prices is that we were unable to determine the extent to which consumers actually paid these prices and in what volume the products were sold, and our results are not generalizable to the broader universe of prices for these products sold at other times or by other online retailers. Though we found that the target gender for a product is a significant factor contributing to price differences we identified, we do not have sufficient information to determine the extent to which these gender- related price differences were due to gender bias as opposed to other factors. Versions differentiated to appeal to men and women can result in different costs for the manufacturer. Our econometric analysis controlled for many observable factors related to costs, such as product size, promotional activity, and packaging type. We also controlled for many product attributes such as forms, scents, and special claims that products make to account for underlying manufacturing cost differences. In addition, we controlled for brands, which can reflect consumer preferences. However, we do not have firm-level data on all cost differences—for example, those related to advertising and packaging. As a result, we could not determine the extent to which the price differences we observed may be explained by remaining cost differences between men’s and women’s products. We also do not have the data to determine the extent to which men and women have different demands and willingness to pay for a product, which would be expected to affect the prices firms charge for differentiated products. For example, some academic experts we spoke with said that women may value some product attributes, such as design and scent, more than men do. If products differentiated to incorporate those attributes do not result in different costs, then differences in prices could be part of a firm’s pricing strategy based on the willingness of one gender to pay more than another. The conditions necessary for firms to be able to implement a strategy of price differentiation likely exist for the personal care products we analyzed. First, our analysis suggests that due to industry concentration, there is limited market competition for the 10 personal care products we analyzed. With more market power, firms can more easily set different prices for different consumer segments. Second, firms have the ability to segment the market for personal care products by tailoring product characteristics related to gender, such as by labeling the product as women’s deodorant or men’s deodorant, or by altering scent or colors. Third, while men and women are able to freely purchase a product targeted to the opposite gender, certain factors may limit the extent to which this occurs. For example, some product differences such as scents may discourage one gender from buying products targeted to another gender. In addition, consumers may find it difficult and time- consuming to compare prices for similar men’s and women’s products because of the ways they are differentiated (such as product size and scents) and because they may be sold in different parts of a store. We reviewed studies that compared prices for men and women in four markets where the product or service is not differentiated by gender: mortgages, small business credit, auto purchases, and auto repairs. First, we reviewed studies on mortgage and small business credit that analyzed interest rates and access to credit to identify any differences for men and women. Second, we reviewed studies that compared prices quoted to men and women in auto purchase and repair markets. However, several of these studies have important limitations, such as using nonrepresentative data samples, and the results are not generalizable. Studies we reviewed found that women as a group pay higher interest rates on average than men in part due to weaker credit characteristics. After controlling for borrower credit characteristics and other factors, three studies did not find statistically significant differences in interest rates between men and women for the same type of mortgage, while one study found that women paid higher mortgage rates for certain subprime loans. In addition, one study found that female borrowers defaulted less frequently on their loans than male borrowers with similar credit characteristics, suggesting that women as a group may pay higher mortgage rates than men relative to their default risk. While these studies attempted to control for factors other than gender or sex that could affect borrowing costs, several lacked important data on certain borrower risk characteristics. For example, several studies we reviewed rely on Home Mortgage Disclosure Act of 1975 (HMDA) data, which did not include data on risk factors such as borrower credit scores that could affect analysis of disparities between men and women. Also, several studies analyzed nonrepresentative samples of loans, such as subprime loans or loans originated more than 10 years ago, which limits the generalizability of the results (see table 2). Three of the studies we reviewed found that while women on average were charged higher interest rates on mortgage loans than men, this difference was not statistically significant after controlling for other factors. For example, one study found that differences in mortgage interest rates between men and women became insignificant after controlling for differences in how men and women shop for mortgage rates. The authors used data from the 2004 Survey of Consumer Finances (SCF) to analyze the effect on interest rates of mortgage features, borrower characteristics such as gender, and market conditions. However, their analysis did not include data on some borrower credit characteristics such as credit score and debt-to-income ratio that could affect borrowing costs. Another study found that women were charged higher interest rates for subprime loans made in 2005, but once the authors controlled for observed risk characteristics there was no evidence of disparity in interest rates by gender of the borrower in the subprime market. However, the authors’ data did not include any fees paid at loan origination, which could affect the overall cost of borrowing. A third study that examined disparities between men and women in subprime loans found no significant evidence that gender affected the cost of borrowing within the subprime market, though it did find that women—particularly African American women—were more likely to have subprime loans. The authors found that, even after controlling for some financial characteristics and loan terms, single African American women were more likely than non-Hispanic white couples to have subprime loans. One study analyzed subprime loans made by one large lender from 2003 through 2005 and found that women paid more for subprime mortgages than men after controlling for some risk factors. This study found that women had higher average borrowing costs—as measured by annual percentage rate—than men, and controlling for credit characteristics such as credit scores and debt-to-income ratios did not fully explain the differences. However, the authors did not control for other factors that could also affect borrowing costs, such as differences in education, shopping behaviors, and geographic location. Additionally, a research paper found that female-only borrowers—that is, where the only borrower is a woman—default less than male-only borrowers with similar loans and credit characteristics. The authors found that female-only borrowers on average pay more for their mortgage loans because they generally have weaker credit characteristics, such as lower income, and also because a higher percentage of these mortgage loans are subprime. However, after controlling for credit characteristics such as credit score, loan term, and loan-to-value ratio, among others, the analysis showed that these weaker credit characteristics do not accurately predict how well women pay their mortgage loans. Since pricing is tied to credit characteristics and not performance, women may pay more relative to their actual risk than do similar men. Studies we reviewed on small business loans generally did not find differences in interest rates, though some found differences in denial rates and other accessibility issues between female- and male-owned firms. Most of the studies we reviewed used data from the 1993, 1998, or 2003 Survey of Small Business Finances (SSBF), which could limit the applicability or relevance of their findings today. A study that analyzed data from the 1993 SSBF did not find evidence that businesses owned by women paid more for credit than firms owned by white men. However, when the authors took into account the market concentration and competition, they found that white female-owned firms experienced increased denial rates in less competitive markets. In addition, the study found that women may avoid applying for credit in those markets because of the fear of being denied. For example, almost half of all small business owners who needed credit reported that they did not apply for credit, and these rates were even higher for businesses owned by women and minorities. Other studies found that women may have less access to small business credit than men, in part because of higher denial rates and because they may not apply for credit out of fear of rejection. For example, one study found that women-owned firms have higher loan denial rates compared with men; however, this is mainly due to differences in business characteristics of female- and male-owned firms. The authors also found that even when denial rates are the same for small businesses with similar characteristics, women’s loan application rates are lower, suggesting that women may be discouraged from applying for credit by the higher overall denial rates for female-owned firms. Another study by one of the same authors examined the reasons why female borrowers may be discouraged from applying for a business loan compared to male business owners and found that it was mainly because they fear that their application will be rejected. A third study by the same author found that women in general did not have less access to credit than men, though newer female-owned firms received significantly lower loan amounts than requested compared to their male-owned counterparts. Similarly, the study also found that women with few years of experience managing or owning a business received significantly lower loan amounts compared with men with similar years of experience. A fourth study looked at six different types of loans, including lines of credit, and found that white women were significantly more likely than white men to avoid applying for a loan because they assume they would be denied. However, once the authors’ model controlled for education differences, all gender disparities in applying for credit disappeared, though white women were still less likely than white men to have loans. Studies we reviewed on auto purchases and repairs found that a seller’s expectation of what customers are willing to pay and how informed they seemed can differ by gender, which can affect the price customers are quoted. However, these studies were published in 1995 and 2001, which may limit the applicability or relevance of their findings today. The 2001 study we reviewed on auto purchases found that though women paid higher prices than men for car purchases on average, these differences declined when cars were purchased online. The authors suggest that this may be because Internet consumers can effectively convey their level of price knowledge and therefore may seem better informed to the sellers. They also suggest it could be because the dealerships have less information about online consumers and their willingness to pay, which may limit the extent of price differentiation. The 1995 study on auto purchases found that the dealers quoted significantly lower prices to white males than to female or African American test buyers using identical, scripted bargaining strategies in part because dealers may have made assumptions about women’s willingness to bargain for lower prices. We also reviewed one study on auto repairs that found that women were quoted higher prices than men if they seemed uninformed about the cost of car repair when requesting a quote, but the price differences disappeared if the study participant mentioned an expected price. The study suggests that a potential explanation for this result could be that auto repair shops expect women to accept a price that is higher than the market average and men to accept a price below it. BCFP and HUD have responsibilities to monitor consumer complaints in the consumer credit and housing markets, respectively. Additionally, FTC monitors complaints about the consumer credit and consumer goods markets. All three agencies play a role in potentially monitoring or addressing issues of gender-related price differences and have online complaint forms for submission of consumer complaints: BCFP collects and reviews consumer complaints about financial products and services and provides complaints and related data in its Consumer Complaint Database. In 2017 BCFP received approximately 320,200 consumer complaints. The products that generated the most complaints in 2017 were “Credit or consumer reporting,” “Debt collection,” and “Mortgage." According to BCFP officials, BCFP also analyzes loan and demographics data collected through HMDA and other data sources to monitor and identify market trends. In addition, BCFP and the federal financial regulators examine fair lending practices of the institutions they regulate, and these examinations have uncovered sex discrimination in credit products by FDIC and NCUA. FTC receives complaints and the complaints are stored in the Consumer Sentinel Network, a database of consumer complaints received by FTC, as well as those filed with other federal and state agencies and organizations, such as mass marketing fraud complaints from the Council of Better Business Bureaus. The complaints in the Consumer Sentinel Network focus on consumer fraud, identity theft, and other consumer protection matters, such as debt collection, and can include complaints related to consumer credit markets. HUD receives consumer complaints about potential FHA violations through its website, via its toll-free phone hotline, and in writing. HUD monitors those complaints through its online HUD Enforcement Management System. HUD investigates all complaints for which it has jurisdictional authority. HUD may monitor complaints to identify trends, but HUD officials stated that the agency does not generally monitor consumer credit and housing market data, absent a specific complaint. In cases where HUD has jurisdictional authority under FHA, HUD offers conciliation between the parties. If resolution is not reached, and HUD determines there is reasonable cause to believe a violation has occurred, the parties may elect to have the matter heard in U.S. District Court or at HUD. In their oversight of federal antidiscrimination statutes, BCFP officials said they have not identified significant consumer concerns about price differences based on a consumer’s sex or gender. FTC and HUD officials identified some examples of concerns of this nature. For example, FTC has taken enforcement actions alleging unlawful race- and gender-related price differences. HUD has also identified several cases where pregnant women and their partners applied for a mortgage while the woman was on maternity leave, and the couple’s mortgage loan application was denied. BCFP, FTC, and HUD have received few consumer complaints about price differences related to sex or gender, according to our analysis of a sample of each agency’s 2012–2017 complaint data (see table 3). In separate samples of 100 gender-related complaints at BCFP, HUD, and FTC, we found that 0, 4, and 1 complaint, respectively, were related to price differences based on sex or gender. Three of the complaints from HUD also cited differences in price based on other protected classes (such as race or ethnicity). Half of the academic experts and consumer groups we interviewed told us that in some markets it is difficult for consumers to observe and compare prices paid by other consumers, such as when prices are not posted or can be negotiated (e.g., car sales). In such cases, consumers may not know if other consumers are paying a higher or lower price than the price quoted to them. Most academic experts also told us that when consumers are aware that price differences could exist, they may make different decisions when making purchases. Additionally, officials from BCFP noted that price differences related to gender may be difficult for consumers to identify, or that consumers may not know where to complain. The consumer education resources of BCFP, FTC, and HUD provide general consumer education resources on discrimination (i.e., consumer user guide or a website) and consumer awareness. Officials from BCFP and HUD said they have not identified a need to develop other consumer education resources specific to gender-related price differences. For example, BCFP’s print and online consumer education materials are intended to inform consumers of their rights and protections related to credit discrimination, which includes discrimination based on sex or gender. The three agencies’ consumer education materials also provide advice that could help consumers avoid paying higher prices regardless of their gender—such as home-buying resources and resources on comparison shopping. However, the agencies have not developed additional educational resources focused specifically on potential gender- related price differences in part because few complaints on this topic have been collected in their databases, agency officials told us. FTC officials noted that it tries to focus its education efforts on topics that will have the greatest benefit to consumers, often determined by information it gathers through complaints and investigations. Representatives of five consumer groups and industry associations told us that they have received few complaints about gender-related price differences. However, four consumer groups noted that low concern could be the result of consumers being unaware of price differences related to gender. For example, as indicated above, price differences related to gender may be difficult for consumers to identify when they cannot determine whether they are paying a higher price than others. Representatives of two retailing industry associations similarly stated that they have not heard concerns about price differences related to gender. In response to consumer complaints or concerns about gender disparities in pricing, at least one state (California) and two municipalities (Miami- Dade County and New York City) have passed laws or ordinances to prohibit businesses from charging different prices for the same or similar goods or services solely based on gender (see table 4). In addition, two of these laws included requirements related to promoting price transparency. California enacted the Gender Tax Repeal Act of 1995, which prohibits businesses from charging different prices for the same or similar services based on a consumer’s gender. The law also requires certain businesses to display price information and disclose prices upon request, according to state officials with whom we spoke. Similarly, in 1997, Miami-Dade County passed the Gender Pricing Ordinance, which prohibits businesses from charging different prices based solely on a consumer’s gender (though businesses are permitted to charge different prices if the goods or services involve more time, difficulty, or cost). In the same year, it also passed an ordinance that prohibits dry cleaning businesses from charging different prices for similar services based on gender. This ordinance also requires those businesses to post all prices on a clear and conspicuous sign, according to county officials with whom we spoke. State and local officials we interviewed identified benefits and challenges associated with these laws. For example, California, New York City, and Miami-Dade County officials noted that these laws give them the ability to intervene to address pricing practices that may lead to discrimination based on gender. In addition, California state officials said that the state’s efforts to implement the Gender Tax Repeal Act helped to improve consumer awareness about gender price differences. However, officials from California and Miami-Dade County cited challenges associated with tracking relevant complaints. For example, Miami-Dade County’s online complaint form includes a narrative section but does not ask for the complainant’s gender. Consumers do not always identify their gender in the narrative or state that that was the reason for their treatment. Additionally, officials from California and Miami-Dade County stated that seeking out violations would be very resource-intensive, and they rely on residents to submit complaints about violations. We provided a draft of this report to BCFP, DOJ, FTC, and HUD. BCFP, FTC, and HUD provided technical comments on the report draft, which we incorporated where appropriate. As agreed with your offices, unless you publicly announce the contents of this report earlier, we plan no further distribution until 30 days from the report date. At that time, we will send copies to the appropriate congressional committees, BCFP, DOJ, FTC, HUD, and other interested parties. In addition, the report will be available at no charge on the GAO website at http://www.gao.gov. If you or your staff have any questions about this report, please contact me at (202) 512-8678 or cackleya@gao.gov. Contact points for our Offices of Congressional Relations and Public Affairs may be found on the last page of this report. GAO staff who made key contributions to this report are listed in appendix VI. We used a multivariate regression model to estimate the effect of gender (to which a product is targeted to) on the price of that product while controlling for other factors that may also affect the product’s price. The factors that we controlled for were the product size, promotional and packaging costs, and other product characteristics discussed in detail later. We used scanner data from the Nielsen Company (Nielsen) for calendar year 2016 and analyzed the following 10 product categories: (1) underarm deodorants, (2) body deodorants, (3) shaving cream, (4) shaving gel, (5) disposable razors, (6) nondisposable razors, (7) razor blades, (8) designer perfumes, (9) mass-market perfumes, and (10) mass-market body sprays. We estimated the following regression model for each of our 10 product categories: P=α+β*Male + λ* Size + θ*Owner +η*Promotion+ μ*X + δ*Y + ε The dependent variable P in the above equation represents price. For our analysis, we constructed two measures of price. The first is the item price, estimated as the total dollar sales of an item (each item is depicted by a unique Universal Product Code (UPC) in the Nielsen data), divided by the total units sold of that item. The second measure of price that we use is price per ounce or price per count. This is estimated as the item price divided by the total quantity of product, where quantity or size depicts the number of ounces (as in the case of fragrances) or the count of blades in razor blade packs. The total quantity of the product is the ounces or counts of one item multiplied by the number of items included in a specific product configuration. For example, a 2-pack of deodorant sticks where each deodorant stick is 2.7 ounces would be a total quantity of 5.4 ounces. The variable Male in the above equation is an indicator variable depicting whether the product is designated as a “men’s” product in the Nielsen data. It is represented as a value of “1” for men’s products and a value of “0” for women’s products. The co-efficient for this variable, parameter β, would therefore show the price difference between a men’s and women’s product. A negative value would imply a lower price for products designated as men’s products. The variable Size represents the most appropriate specification of the size of the product. Owner is a set of indicator variables representing all the brand owners selling a particular product. The brand of a product can be expected to have a substantial effect on prices for the kind of products we analyze because brands can be a proxy for quality for some consumers. However, we also found that firms often create gender-specific brands, so holding brands constant rendered most gender-based price comparisons infeasible. To overcome this, we hold owners instead of brands constant for our price comparison analysis. The variable Promotion represents the percentage of dollar sales that were sold on any type of promotion. This variable proxies for promotional costs to some extent based on the assumption that the greater the proportion of sales due to promotional activity, the greater the promotional costs. The variables X represent a set of indicator variables for packaging characteristics such as package delivery method (for example, roll-on or aerosol spray deodorants) or package shape (for example, bottle, tube, or can). We expect these characteristics to proxy for different costs associated with different packaging methods. The variables Y represent a set of indicator variables representing different product characteristics (for example, forms such as gel stick or smooth solid and claims such as “active cooling” or “anti-wetness” for underarm deodorants, and blade types such as “triple edge” and “flexible six” for razors). These product characteristics may proxy for some underlying manufacturing costs or even consumer preferences. Since firms may create gender-specific product attributes—scents like “sweet petals” and “pure sport” or razor head types and colors to differentiate products between genders—we did not always keep every product attribute constant when comparing prices. The idiosyncratic error term is represented by ε. All of our regressions are weighted, with the proportion of units sold for a particular item in that year as the weight. This is because, for personal care products, there are large differences in units sold of various product types and brands, and therefore it not useful to compare simple un- weighted average prices. For example, for one company the highest selling men’s deodorant stick sold almost 12 million units in 2016, and the highest selling women’s deodorant stick sold over 8 million units. The average units sold for underarm deodorants as a whole was just over 300,000 units, and 1,000 products out of a total of almost 3,000 products had less than 100 units sold in 2016. The linear model we used has the usual shortcomings of being subject to specification bias to the extent the relationship between price and each of the independent variables is not linear. The model also does not include complete data on costs, such as advertising and packaging, or consumers’ willingness to pay, both of which have an effect on the price differences. The model may thus also be subject to omitted variable bias. In addition, the model may have some endogeneity issues to the extent the product characteristics themselves are influenced by consumers’ willingness to pay for some of those product features. To reduce the impact of any model misspecifications or heteroscedasticity, we used the robust (or Huber-White sandwich) estimator. We estimated the regression model above for each of the 10 products separately and for each of the two measures of price. We used Nielsen’s in-store, retail price scanner data, which include information on total volume sold and dollar sales for items purchased at 228 retailers including grocery stores, drug stores, mass merchandisers (such as Target), dollar stores, club stores (such as Sam’s Club), and convenience stores. The data capture 82 percent of all U.S. sales. Nielsen also projects sales for the remaining noncooperating retailers, and that information is included in this dataset. We excluded some very small brands that did not have enough units sold from our regression analysis in order to avoid outliers. These brands usually had less than 50,000 units sold over the entire year, and for some products they represented less than 1 percent of all units sold. We found that average retail prices paid were significantly higher for women’s products than for men’s in 5 out of 10 personal care products. In 2 categories, men’s versions sold at a significantly higher price. One category had mixed results based on two price measures analyzed, and two others showed no significant gender price differences. A summary of our regression results is presented in table 5. We manually collected prices for 16 pairs of selected personal care products from the websites of four online retailers that also operated physical store locations. We selected comparable pairs of similar men’s and women’s products that were differentiated by product attributes, such as scent or color, and were sold at most or all of the four retailers. The products were selected based on several comparability factors such as brand, product claims, and number of blades in a razor. For two 1-week time periods in January and March 2018, we collected prices manually between 1:00 p.m. and 7:00 p.m. (ET) over two 7-day time periods. We collected listed prices and did not adjust the prices for any promotions that were available, such as online coupons or buy-one-get-one-free offers. Table 6 presents the results of our online price collection. These results have important limitations: The average prices shown are not generalizable to the broader universe of prices for these products sold at other times or by other online retailers. The data reflect prices advertised to consumers rather than the prices consumers actually paid. The data do not capture the volume of sales for each item for each retailer; in our analysis, we weighted all advertised prices equally across the retailers. As a result, differences we found within these advertised prices may not have translated into comparable differences in prices female and male consumers paid for these products online. The prices do not reflect any promotional discounts, volume discounts, or other discounts that may have been available to some or all consumers. This report examines (1) how prices compared for selected categories of consumer goods that are differentiated for men and women, and potential reasons for any significant price differences; (2) what is known about the extent to which men and women may pay different prices in, or experience different levels of access to, markets for credit and goods and services that are not differentiated based on gender; (3) the extent to which federal agencies have identified and taken steps to address any concerns about gender-related price differences; and (4) state and local government efforts to address concerns about gender-related price differences. To compare prices for selected goods that are differentiated for men and women, we purchased and analyzed Nielsen Company (Nielsen) data on retail prices paid for 10 personal care product categories for calendar year 2016. The product categories included underarm deodorants, body deodorants (typically sold as a spray), disposable razors, nondisposable razors, razor blades, shaving creams, shaving gels, and three categories of fragrances. We selected these categories of personal care products because they are commonly purchased consumer goods that were categorized by gender in the Nielsen data. The women’s and men’s versions of personal care products we selected are generally more similar in terms of the form, size, and packaging in comparison to certain other consumer product categories that are also differentiated by gender, such as clothing. We used regression models to analyze data on retail prices paid for the 10 categories of personal care products differentiated for women and men. To assess the reliability of the Nielsen data, we reviewed relevant documentation and conducted interviews with Nielsen representatives to review steps they took to collect and ensure the reliability of the data. In addition, we electronically tested data fields for missing values, outliers, and obvious errors. We determined that these data were sufficiently reliable for our purposes. For more details on the methodology for, and limitations of, our analysis of these retail price data, see appendix I. We also manually collected listed prices for 16 pairs of selected personal care products from four different retailer websites over two 7-day periods in January and March 2018. For each pair, we selected comparable men’s and women’s products that were differentiated by product attributes, such as scent or color, and were commonly sold across retailers. For more details on our online price data collection and the limitations associated with interpreting the results, see appendix II. To examine what is known about the extent to which men and women may be offered different prices or access for the same goods or services, we reviewed academic literature identified through a literature search covering the last 25 years. To identify existing studies from peer-reviewed journals, we conducted searches using subject and keyword searches of various databases, such as EconLit, Scopus, ProQuest, and Social SciSearch. We also used a snowball search technique—meaning we reviewed relevant academic literature cited in our selected studies—to identify additional studies. We performed these searches and identified articles from December 2016 to April 2018. From these searches, we identified 21 studies that appeared in peer-reviewed journals or research institutions’ publications from 1995 through 2016 and were relevant to gender-related price differences for the same products. We reviewed and assessed each study’s evaluation methodology based on generally accepted social science standards. See the bibliography at the end of this report for a list of the 21 studies. We then summarized the research findings. A GAO economist read and assessed each study, using the same data collection instrument. The assessment focused on information such as the types of disparities examined, the research design and data sources used, and methods of data analysis. The assessment also focused on the quality of the data used in the studies as reported by the researchers and any limitations of data sources for the purposes for which they were used. A second GAO economist reviewed each completed data collection instrument to verify the accuracy of the information included. As a result, the 21 studies that we selected for our review met our criteria for methodological quality. We found the studies we reviewed to be reliable for purposes of determining what is known about price differences for the same products. However, these studies have important limitations, such as using nonrepresentative data samples, and the results are not generalizable. To examine the federal role in overseeing gender-related price differences, we reviewed relevant federal statutes and agency guidance, and interviewed officials from the Federal Trade Commission (FTC), Bureau of Consumer Financial Protection (BCFP), the Department of Housing and Urban Development (HUD), and the Department of Justice (DOJ). To help identify the extent of concerns about gender-related price differences, we interviewed representatives from eight consumer groups, three industry associations, and four academic experts. Additionally, we reviewed a sample of consumer complaints from databases managed by BCFP, FTC, and HUD (Consumer Complaint Database, Consumer Sentinel Network, and Enforcement Management System, respectively). Complaints were submitted by consumers across the United States about various financial products, housing grievances, and other consumer protection concerns. To identify our universe of gender-related consumer complaints in BCFP and FTC databases, we used the following search terms that targeted sex or gender discrimination: discriminat, unfair, treat, decept, abus, female, woman, women, man, men, male, gender, sex, female, woman, women, man, men, male, gender, and sex. HUD’s consumer complaint database is categorized by protected class (e.g., race, sex, national origin), so we did not need to use search terms to identify gender-related complaints. For the years 2012 through 2017, we identified 6,117 BCFP consumer complaint narratives; 10,472 FTC consumer complaints narratives; and 5,421 HUD consumer complaint narratives that were relevant to our scope. We then drew a stratified random probability sample of 100 gender-related consumer complaints from each database. To determine which complaints in our samples were about price differences related to gender or sex, two team members read through each complaint narrative and coded whether or not the complainant’s narrative indicated that they felt that they paid or were charged more because of their gender or sex. A third team member conducted a final review of the results, and made a final determination in cases where there were differences in the first two team member’s assessments. With this probability sample, each member of the study population had a nonzero probability of being included, and that probability could be computed for any member. We followed a probability procedure based on random selections and our sample is only one of a large number of samples that we might have drawn. Since each sample could have provided different estimates, we express our confidence in the precision of our particular sample’s results as a 95 percent confidence interval (with a margin of error of 5.9 percent). This is the interval that would contain the actual population value for 95 percent of the samples we could have drawn. We assessed the reliability of these data by reviewing documentation and interviewing agency officials about the databases used to collect these complaints. We determined that these data were sufficiently reliable for our purposes of identifying complaints of gender- related price differences. To explore state and local efforts to address concerns about gender- related price differences, we conducted a literature search and identified three state or local laws or ordinances that specifically address gender- related price differences: California, Miami-Dade County, Florida, and New York City, New York. We reviewed these laws and ordinances and interviewed officials from these jurisdictions to discuss motivations for, oversight of, and the impact of these laws. We conducted this performance audit from October 2016 to August 2018 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives. For each of 10 personal care product categories we analyzed, we compared the overall average prices for women’s products and men’s products using two measures of average price: average item price and average price per ounce or count. While the second price measure adjusts the average price for quantity of product, these comparisons did not take into account the effect on price of differences in product brand, packaging, and other characteristics. As shown in table 7, adjusting the average item price to account for differences in product quantity (ounces or count) significantly affected the size and magnitude of gender price differences for several product categories. This is because men’s products in the dataset were frequently larger in size or count compared with women’s products in the same category. For example, women’s disposable razors sold for 11 percent less than those targeted to men when we compared average item prices. However, when we compared average price per count of razors, women’s disposable razors sold for 19 percent more on average than men’s. This is because women’s disposable razors had on average about one fewer razor per package. In 5 out of 10 product categories, women’s versions of the product on average sold for a higher price per ounce or count than men’s and these differences were statistically significant at the 95 percent confidence level for 4 products and at the 90 percent level for one product. Information about sales and relative sizes of different products targeted to men and women are presented in table 8 below. This appendix provides additional details about the consumer complaint processes at the Bureau of Consumer Financial Protection (BCFP), Federal Trade Commission (FTC), and Department of Housing and Urban Development (HUD). Consumers with a complaint about unfair treatment related to gender could submit a complaint to one of these agencies. BCFP and FTC monitor consumer complaints related to violations under the Equal Credit Opportunity Act, while HUD and the Department of Justice (DOJ) investigate housing discrimination complaints under the Fair Housing Act. These complaints could be about price differences because of gender. Alicia Puente Cackley, (202) 512-8678 or cackleya@gao.gov.

Answer: Gender-related price differences occur when consumers are charged different prices for the same or similar goods and services because of factors related to gender. While variation in costs and consumer demand may give rise to such price differences, some policymakers have raised concerns that gender bias may also be a factor. While the Equal Credit Opportunity Act and Fair Housing Act prohibit discrimination based on sex in credit and housing transactions, no federal law prohibits businesses from charging consumers different prices for the same or similar goods targeted to different genders. GAO was asked to review gender-related price differences for consumer goods and services sold in the United States. This report examines, among other things, (1) how prices compared for selected goods and services marketed to men and women, and potential reasons for any price differences; (2) what is known about price differences for men and women for products not differentiated by gender, such as mortgages; and (3) the extent to which federal agencies have identified and addressed any concerns about gender-related price differences. To examine these issues, GAO analyzed retail price data, reviewed relevant academic studies, analyzed federal consumer complaint data, and interviewed federal agency officials, industry experts, and academics. Firms differentiate many consumer products to appeal separately to men and women by slightly altering product attributes like color or scent. Products differentiated by gender may sell for different prices if men and women have different demands or willingness to pay for these product attributes. Of 10 personal care product categories (e.g., deodorants and shaving products) that GAO analyzed, average retail prices paid were significantly higher for women's products than for men's in 5 categories. In 2 categories—shaving gel and nondisposable razors—men's versions sold at a significantly higher price. One category—razor blades--had mixed results based on two price measures analyzed, and two others—disposable razors and mass-market perfumes—showed no significant gender price differences. GAO found that the target gender for a product is a significant factor contributing to price differences identified, but GAO did not have sufficient information to determine the extent to which these gender-related price differences were due to gender bias as opposed to other factors, such as different advertising costs. Though the analysis controlled for several observable product attributes, such as product size and packaging type, all underlying differences in costs and demand for products targeted to different genders could not be fully observed. Studies GAO reviewed found limited evidence of gender price differences for four products or services not differentiated by gender—mortgages, small business credit, auto purchases, and auto repairs. For example, with regard to mortgages, women as a group paid higher average mortgage rates than men, in part due to weaker credit characteristics, such as lower average income. However, after controlling for borrower credit characteristics and other factors, three studies did not find statistically significant differences in borrowing costs between men and women, while one found women paid higher rates for certain subprime loans. In addition, one study found that female borrowers defaulted less frequently than male borrowers with similar credit characteristics, and the study suggested that women may pay higher mortgage rates than men relative to their default risk. While these studies controlled for factors other than gender that could affect borrowing costs, several lacked important data on certain borrower risk characteristics, such as credit scores, which could affect analysis of gender disparities. Also, several studies analyzed small samples of subprime loans that were originated in 2005 or earlier, which limits the generalizability of the results. In their oversight of federal antidiscrimination statutes, the Bureau of Consumer Financial Protection, Federal Trade Commission, and Department of Housing and Urban Development have identified limited consumer concerns based on gender-related pricing differences. GAO's analysis of complaint data received by the three agencies from 2012–2017 found that they had received limited consumer complaints about gender-related price differences. The agencies provide general consumer education resources on discrimination and consumer awareness. However, given the limited consumer concern, they have not identified a need to incorporate additional materials specific to gender-related price differences into their existing consumer education resources.
