Question

What did Reagan do to encourage economic growth?

Answer 1

According to the researches, Reagan did implement tax cuts. He did cut the corporate tax rates from 48 to 34 percent in order to combat inflation.

Inflation is where a sustained increase in the general goods and the services are attained in an economy in a period of time. 

Reagan issued tax cuts including the 70 percent top tax rate and decreased it to 50 percent. It also says that Reagan had encouraged economic expansions that would be enough to widen the tax base over a period of time.

Answer 2

Reagan implemented tax cuts 

Perhaps most famous of Reagan's economic policy is Reagan's emphasis on tax cuts, based on his administration's emphasis on "supply side economics" or what has commonly been called "trickle-down economics."  The idea was that if you provided tax cuts to those at the top running business, they would invest more in their business, hire more workers, pay better wages, etc.  Whether that's how it actually worked out is debated.

Reagan did also to some extent support deregulation of industries, but deregulation moves had begun before his administration and economists debate whether that was a high priority for the Reagan administration.
