Final answer:
The comparative cost is the correct answer, as intranets provide a cost-effective platform for businesses to distribute information and manage operations, impacting discussions about firm size among economists and policymakers.
Step-by-step explanation:
The comparative cost of publishing and accessing multimedia business information internally via intranet websites has been one of the primary reasons for the explosive growth in the use of intranets in business. The cost-effectiveness of intranets allows businesses to quickly and economically distribute information while managing operations across various locations. This technological advancement supports both small and large firms by facilitating global reach for the former, and operational management at scale for the latter, leading to ongoing discussions among economists, businesspeople, and policymakers regarding the optimal firm size in the modern market landscape.
