``` Since retailers usually charge the same price regardless of payment method, payment card rewards programs with different levels of rewards effectively cause some customers to subsidize the consumption of others. The research presented confirms that households with income less than $75,000 per year collectively transfer over $3.5 billion to those making more than $75,000 per year. Furthermore, the cost of interchange fees to retailers can be significant, especially in competitive sectors such as gasoline and groceries. This study demonstrates that interchange costs are typically about 17 to 19 percent of retailer profit. Variance in these costs may induce risk-averse retailers to set higher prices, thus generating additional economic inefficiencies and hurting retail consumers. Negative impacts on low income and minority households and small businesses have become “entrenched” and are likely to get worse as interchange fees continue to increase. This economic inefficiency will not change unless there is a “sufficiently large shock” in the form of policy or technology to change the dynamics of the monopolies holding sway over the credit card system. ```
