According to a 1996 study[36] from the libertarian think tank Cato Institute:

* On 8 of the 10 key economic variables examined, the American economy performed better during the Reagan years than during the pre- and post-Reagan years.
* Real median family income grew by $4,000 during the Reagan period after experiencing no growth in the pre-Reagan years; it experienced a loss of almost $1,500 in the post-Reagan years.
* Interest rates, inflation, and unemployment fell faster under Reagan than they did immediately before or after his presidency.
* The only economic variable that was worse in the Reagan period than in both the pre- and post-Reagan years was the savings rate, which fell rapidly in the 1980s.
* The productivity rate was higher in the pre-Reagan years but much lower in the post-Reagan years.

Stephen Moore of the Cato Institute stated that "no act in the last quarter century had a more profound impact on the US economy of the eighties and nineties than the Reagan tax cut of 1981." He claims that Reagan's tax cuts, combined with an emphasis on federal monetary policy, deregulation, and expansion of free trade created a sustained economic expansion creating America's greatest sustained wave of prosperity ever. The American economy grew by more than a third in size, producing a $15 trillion increase in American wealth. Every income group, from the richest, middle class and poorest in this country, grew its income (1981–1989). Consumer and investor confidence soared. Cutting federal income taxes, cutting the US government spending budget, cutting useless programs, scaling down the government work force, maintaining low interest rates, and keeping a watchful inflation hedge on the monetary supply was Ronald Reagan's formula for a successful economic turnaround. The last principle Ronald Reagan incorporated was the realization that immigrant workers are a key and vital component of the US economy
