The typical firm adjusts its prices b. about once a month due to cost and customer considerations.
Step-by-step explanation:
The subject of this question is business. Alan Blinder's survey found that the typical firm adjusts its prices b. about once a month.
Many firms do not change their prices every day or even every month due to the costs involved in changing prices, such as analyzing competition, market demand, updating sales materials, and redoing product and price labels. This process, known as menu costs, takes time and can leave customers confused or angry if prices change frequently.
