Question

Will supply side policies always increase the efficiency of uk manufacturing companies?

Answer 1

To properly execute supply-side economic policy, there must be a decrease in individual and corporate taxes, deregulation of businesses, and government subsidies to encourage business growth.  A tax cut will leave both individuals and businesses with more cash to spend on potential investments. From the standpoint of uk manufacturing companies, supply side economic policies are the best form of economic policy because it would cause more efficiency for producers, and more money to spend on potential investments.

If government spending exceeds government revenue (through taxation) then overtime this can build up a tremendous national debt for the UK and cause inflation in the country (this is what happened after Reagan's presidency in the US).
