Donald Trump will win the US presidential election, according to a business school model developed by French and Swiss professors.
The data analysed by the model shows 'a clear win for Trump', even though the professors said this is one of the hardest presidential election to predict in the past century.
The charisma of the candidates and the state of the US economy were the two key factors which the model took into account.
The research shows that a candidate's charisma is only important to voters when the state of the economy is unclear.
As a result, although the model shows that Hillary Clinton is the more charismatic of the two candidates, the poor economic indicators favour a Republican win.
According to a Reuters poll taken on 28 August, Trump does hold a marginal lead, with 39.7% of those polled expecting to vote for him versus Clinton's 39% support.
However, a Washington Post/ABC poll conducted by telephone between 5-8 September suggests Clinton still leads with 46% support against Trump's 41% among likely voters.
Professor Philippe Jacquart of the EMLYON Business School, who has analysed data from the last 25 presidential elections, said: "The data we have analysed shows a clear win for Trump.
"However, given both candidate's unique characteristics with Hillary being the first female candidate, and Donald Trump being Donald Trump, I believe this is still an extremely difficult election to call.
"That being said, the results we have here suggest that if the Republicans do not win the presidency, they will have Trump to blame for it."
