Many states have slowed the pace at which they added new regulations or even reduced the total number, but Colorado has moved in the opposite direction and will pay an economic price for doing so, according to a study sponsored by the Colorado Chamber of Commerce. “A lot of these regulations could be considered redundant or excessive,” said Memo Diriker, CEO of StratACUMEN, a business analysis and research firm that spent the past year studying Colorado’s regulatory structure. Diriker, presenting the study results last week on a call with journalists and political leaders, said the number of new rules and regulations in Colorado rose 2% between 2017 and 2020, for a 0.7% annual growth rate.
