Final answer:
Financial assistance such as nonrefundable grants, tax incentives for R&D, and government loan guarantees can reduce tax burdens on tourism developers and support infrastructure development in economically disadvantaged areas.
Step-by-step explanation:
The types of financial assistance from the government that can reduce the tax load on tourism developers include financial incentives such as nonrefundable grants, which direct funds to developers not requiring repayment. Financial incentives can also come in the form of tax incentives created for businesses to invest in Research and Development (R&D), which are similar to the way governments can decrease taxes to stimulate economic growth through the "Trickle Down" theory. Moreover, loan guarantees offered by the government can help tourism developers secure financing by assuring lenders that the government will cover the debt if the borrower defaults. This can be crucial for tourism development in areas where most people live below the poverty line and infrastructure investment might otherwise be diverted to more urgent needs, leaving little for tourism without governmental support.
