Dr. Jodi Halpern, UC Berkeley’s School of Public Health University chair and professor of bioethics as well as the codirector at the Kavli Center for Ethics, Science, and the Public, has plenty of experience in this field. In a career spanning as long as her title, Halpern has spent 30 years researching the effects of empathy on recipients, citing examples like doctors and nurses on patients or how soldiers returning from war are perceived in social settings. For the past seven years, Halpern has studied the ethics of technology, and with it, how AI and chatbots interact with humans.
The researchers employ confidential transaction-level data from a major US wine importer covering October 2018 through March 2022. These data include detailed purchase invoices from foreign suppliers and sales invoices to US distributors. The authors supplement this with Connecticut state price-posting data for distributor-to-retailer transactions and retail price data from e-commerce platform Wine-Searcher. They compare price changes for tariffed wines (still wines at or below 14 percent ABV) with price changes for a control group consisting of sparkling wines and still wines exceeding 14 percent ABV from producers selling only nontariffed products.
