Final answer:
Minnesota's commerce commissioner may conduct investigative actions like subpoenaing witnesses and examining records, similar to the U.S. Commerce Department, which also calculates production costs in anti-dumping cases.
Step-by-step explanation:
During an investigation, Minnesota's commerce commissioner has the power to conduct a range of activities. This may include the ability to subpoena witnesses, examine company records, and perform other investigative actions similar to those carried out by federal agencies such as the U.S. Commerce Department. While the question specifically mentions Minnesota, it's important to note that the U.S. Commerce Department is responsible for activities such as calculating the appropriate cost of production in anti-dumping investigations, which involves determining whether products are being sold at unfairly low prices due to being subsidized or priced below cost in the U.S. market. These actions are critical in ensuring fair trade and market practices are upheld.
