Is the polling industry the real loser in the American presidential elections? Pollsters have come in for criticism that they misjudged President-elect Biden’s support, and did even worse in the state senate elections. Andrew Gelman, professor of statistics and political science at Columbia University explains why some of the errors were made. Zeynep Tufekci, associate professor at the University of North Carolina, Chapel Hill, argues that polling can have a distorting effect on democracy itself, changing how people vote or whether they do at all. Meanwhile, Anthony Wells of UK research firm YouGov explains how the polling industry functions outside of the electoral spotlight, and why political forecasts are just a small part of it.

Ahead of the 2021 Climate Change Conference, big names in the world of finance are banding together to create ways to reduce greenhouse gas emissions. With new improved carbon offset markets, monitoring and standardisation of emissions goals and an emphasis on channelling capital to projects based on renewable energy, evangelists of so-called 'Green Finance' believe capitalism can reinvent itself to the benefit of the planet. Rhian-Mari Thomas, chief executive of the Green Finance Institute and convenor of the just-finished Green Horizons Summit, outlines the vision. May Boeve of the environmental group 350.org says much of capital is still directed towards climate-damaging industries. And Bill Winters, chief executive of Standard Chartered, explains how an effective carbon offset market would work.

US President-elect Joe Biden is to make tackling the coronavirus pandemic his top priority following his win over Donald Trump, his team says. Larry Summers, former director of the National Economic Council under President Obama says the country can’t have a healthy economy without a healthy population.

Barry Richard, veteran Florida lawyer who represented then candidate George W. Bush in the 2000 election Supreme Court battle, runs down the merits of those challenges, as well as their flaws.

When they cast their votes for US president, Californians also approved a change to the law allowing gig economy companies like Uber and Lyft to keep treating their drivers as contractors, not employees.

Dave Lee, Silicon Valley correspondent for the Financial Times, tells us what it means for the future of companies like Uber.

Vote counting continues in a handful of key battleground states which will determine the outcome of the US presidential election. Democratic candidate Joe Biden has been projected to win Michigan and Wisconsin. He also holds narrow leads in Nevada and Arizona. If he's able to hang on in all these states as final votes are counted, Mr Biden will be almost certain to win. We take a look at what this means for the US economy. International economics policy analyst Pippa Malmgren joins the show to get us up to speed, and then we’ll hear from Jason Furman, the former chief economic adviser to President Obama, who says Biden’s focus will be on trade policy and manufacturing. Meanwhile, Trump’s own former chief economic adviser Tomas Philipson says the president’s economic achievements have been undervalued. And Mohamed El-Erian of Allianz says the balance between a Democratic executive and a Republican senate will not be the kind of stabilising influence economists usually expect.
