Donald Trump is the least trusted presidential candidate to manage the U.S. economy, according to a new survey of the nation's top economists.

Trump vowed to slash taxes, end corporate tax loopholes and pursue sweeping regulatory reform during a speech earlier this month that introduced, and in some cases modified, his economic agenda.

But more than half of the respondents in a new economic policy survey by the National Association for Business Economics said his opponent, Democratic presidential hopeful Hillary Clinton, would "do the best job" handling the U.S. economy and rising national debt as president.

Fifteen percent said Libertarian nominee Gary Johnson would do the best job, while 14 percent chose Trump.

Not only is Trump seen as the candidate least equipped to handle fiscal and monetary policy, many of the NABE members disagreed with his immigration proposals and opposition to international trade deals.

Nearly 50 percent of respondents said the U.S. should adopt the Trans-Pacific Partnership in its current form, while 30 percent shared in Trump's calls for re-negotiating the trade agreement. An additional 61 percent of respondents said the next president should bring more leniency to employment-based immigration policy, a position that counters Trump's advocacy for a more restrictive approach to immigration.

Only 8 percent of respondents said the U.S. should commit to deporting the 11 million immigrants who came to the country without prior authorization — a plan that Trump previously touted but has reportedly been wrestling with lately.

Despite the outcome of the current presidential election, more than 60 percent of respondents said they look forward to it being over with because the uncertainty is "holding back U.S. economic growth."

The survey of 414 NABE members was conducted between July 20-Aug. 2.
