Louis XIV's government provided various industries with subsidies to help fuel the economy. Think about the industries and social programs that the U. S.
government subsidizes today. How can subsidies help stimulate our current economy?

When government subsidies are implemented to the supplier, an industry is able to allow its producers to produce more goods and services. This increases the overall supply of that good or service, which increases the quantity demanded of that good or service and lowers the overall price of the good or service. In this sense, when the government gives subsidies to the supplier, what results is a win-win situation for both the supplier and the consumer. Essentially, the supplier is benefitting as if the good were selling at a higher price and is able to produce more of the product. Meanwhile, consumers get to enjoy the product for what would be a comparatively cheaper price, since suppliers do not need to charge exorbitant rates to break even on production.
Since the government helps suppliers through tax credits or reimbursements, the lower overall price of their goods and services is more than offset by the savings they receive.
