Economic Impacts of Cement Industry Regulations:
America's economic activity, or gross output, occurred in the cement manufacturing industry. What's more, in addition to federal tax payments by the industry and its employees, almost $931 million in indirect tax revenue was generated for state and local governments. Table 1 only tracks the multipliers from cement manufacturing itself.
