The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Government or policymakers can increase productivity in its citizens by creating the kinds of legislation or economic incentives to invite companies, business owners, and citizens to be more productive.
Sometimes, government officials can allow what is known as "supply-side policies," trying to improve the productivity of companies, businesses, and the economy in general.
This can be accomplished with free-market supply-side strategies to make the market more competitive. The other way could be with the intervention of the government to fix the market.
Examples of the first policy could be deregulation, privatization con companies, or the modification of income taxes. Examples of the second one could be the government investing in public infrastructures such as highways or public schools.
