The American Consumer Institute Center for Citizen Research (ACI) is a non-partisan, public policy think tank that advocates for free markets, especially consumer interests. ACI alleges that consumer interests are not well represented, and claims most advocacy and consumer organizations only represent special interests and small groups of consumers.  ACI focuses its research on economic policy issues like technology, energy and the environment, and taxation. 
The American Consumer Institute contends that excessive business taxes and regulations negatively affect consumer welfare, while reducing competition and job creation.  ACI advocates against the Organization for Economic Cooperation and Development’s 2020 proposal to create a global minimum tax rate. ACI claims that a fixed global tax rate would increase costs for businesses in the U.S., create higher prices for consumers, slow economic growth and job creation, and reduce U.S. tax sovereignty. 
In 2020, the American Consumer Institute opposed the extension of production and investment tax credits used to subsidize wind and solar energy. ACI signed a letter along with twenty-three other organizations, claiming that these energy subsidy extensions are unnecessary and create undue financial burdens on taxpayers and consumers. Other signers of the letter include Americans for Prosperity, the National Taxpayers Union, and the Competitive Enterprise Institute. 
The American Consumer Institute holds that increased regulation of technology companies will negatively impact small businesses and claims that private companies are constitutionally protected to regulate their own businesses. ACI believes that the current federal law concerning technology platform service providers should be revisited in order to address content moderation, instead of states developing their own individual rules. 
The American Consumer Institute advocates for consumer sovereignty, allowing customers the freedom to make their own choices.  ACI contends that the Affordable Care Act (ACA) needs to be revised to include consumer sovereignty, allow for more freedom of choice, and protect people with pre-existing conditions. ACI suggests revising the ACA to include better tools to assist consumers in choosing a plan, in hope that easier navigation would lead to larger enrollments and reduced costs. 
The American Consumer Institute is funded by donations from individuals, foundations, and corporations. While ACI does not disclose its donors, tax filings show donations from R Street Institute, which contributed between 2016 and 2018,  and National Association of Broadcasters, which contributed between 2014 and 2019.
