Using sound fiscal policies to promote macroeconomic stability, such as reducing government expenditure and maintaining modest budget deficits.
Tax Reform
Tax reform entails broadening the tax base and minimizing tax inefficiencies in order to increase efficiency and produce income for public investments and social programs.
Trade Liberization
Trade liberalization refers to the process of opening up the economy to international trade by lowering trade obstacles such as tariffs and import quotas in order to stimulate economic growth and integration into the global economy.
Deregulation
Deregulation is the removal of unneeded rules and bureaucratic impediments to business formation, competition, and investment.
Privatization
Privatization refers to the sale of state-owned firms to the private sector in order to increase efficiency and productivity, promote competition, and attract foreign investment.
Market-oriented Exchange Rates
Adoption of market-based exchange rate systems to reflect supply and demand forces and increase export competitiveness.
Investment in Human Capital
Investing in Human Capital entails improving education and healthcare systems in order to generate a skilled workforce and boost overall productivity.
Secure Property Rights

Extra Notes
