The question of whether Britain should stay in the EU’s customs union has dominated the news cycle recently – with the CBI and other high profile voices suggesting that remaining in the Customs Union would be consistent with Britain’s vote to Leave the EU. But would this be a political possibility? And would it be wise?We’re joined by Julian Jessop, the IEA’s Chief Economist and Head of the Brexit Unit, to give us update on these developments. Julian explains what the Customs Union is, how it differs from the Single Market, and explores some of the pros and cons of staying in it.

The Chancellor asked for ideas for inheritance tax to be simplified this week, but should we even have a death tax at all? On this week’s podcast Simon Lambert, Lee Boyce and Georgie Frost look at how it works, why it is unpopular, and how you can avoid it. Simon suggests his plan to simplify it and get more people paying by removing those fiddly reliefs and slashing the rate to 20%. But we also consider the argument for taxing inheritance (and unearned property wealth) more heavily. Later on the podcast, we discuss the problem of interest-only timebomb mortgages and whether homeowners are burying their heads in the sand. Also on the agenda is what’s wrong with M&S and investing in emerging markets and why they could still be a good long-term bet, even after funds rose almost 30% last year.

The resale of tickets has been around for as long as humans have charged entry to events. Evidence of ticket ‘touting’ goes all the way back to Ancient Rome. In the 21st century though, it’s becoming an increasingly controversial practice. Companies like Viagogo, Seatwave and Stubhub now offer tickets to otherwise hard-to-reach events – but, often, at a hefty price. IEA News Editor Kate Andrews interviews Dr Steve Davies, the IEA’s Head of Education and author of new report Digital Resellers: The case for Secondary Ticket Markets. Steve believes that ticket resale is simply one aspect of the ‘Sharing Economy’ which enables voluntary transactions to take place between willing buyers and sellers. Those who aim to resell tickets for a profit, Steve argues, are themselves taking on considerable risk. Kate and Steve examine the economics, and the morality, of ticket resale, and take a look at the way artists like Ed Sheeran, Taylor Swift and Madonna use market mechanisms to sell their products.
