The economics profession has sought to reinvent itself since the its failure to foresee the 2008 financial crisis.

Manuela Saragosa speaks to two economists: Wendy Carlin discusses her efforts to transform the way economics is taught in universities in order to make it more relevant to the real world; and Mariana Mazzucato explains why she thinks one of the biggest problems is false narratives that have been peddled to policy-makers and the public about how the economy works.

Feminist economists argue that GDP statistics need to start taking account of care-giving and housework if we want to start valuing these things as a society.

For example author Katrine Marcal points out that Adam Smith claimed that the economy was based on self interest, overlooking the fact that his mother cooked his meals for free. Manuela Saragosa speaks to Hannah Peaker of the UK's Women's Equality political party, and professor Joyce Jacobsen of the Wesleyan University in the US.

For most people, a traffic violation simply means a fine. But for poorer people in the US, it could mean being imprisoned. Since the global financial crisis, local and state governments have tried to make up for shortfalls in tax revenue by issuing more, and larger, fines. If you can't afford to pay, you may well end up behind bars, as the BBC's Kim Gittleson reports from South Carolina.

Presenter Ed Butler talks to Robin Steinberg, CEO of the non-profit Bail Project in Los Angeles, which is aimed at helping accused people stay out of jail while they're awaiting trial. And we hear from Lisa Greybill, deputy legal director of the Southern Poverty Law Centre, and North Louisiana defence attorney Eric Johnson, on the pros and cons of working prisoners.

Israeli Prime Minister Benjamin Netanyahu has made fresh allegations against Iran, adding to mounting pressure on the 2015 nuclear deal. What might be the impact on Iran, and for US and European businesses, if the agreement is ultimately scrapped?

We hear from Iran itself and what the threat of fresh sanctions has done to the country's currency, the money in ordinary people's pockets, and their hopes for the future.

But is the average Iranian actually better off since the lifting of sanctions three years ago? Ellie Geranmayeh, from the European Council on Foreign Relations, tells us the promised economic progress hasn't really materialised. One reason is that huge pressure is still being put on firms not to do business with Iran. Californian entrepreneur Honor Gunday, CEO and founder of online money transfer platform Paymentwall, says his firm received a surge of interest from the Islamic Republic after sanctions were lifted, but that he was warned off by US lobby organisations. We speak to one of those, United Against a Nuclear Iran, and its president David Ibsen. Plus, what next for the nuclear deal? UK sanctions lawyer Nigel Kushner and Ellie Geranmayeh tell us we could be in for many months of renegotiations and a possible trans-Atlantic split on the issue.

The leaders of more than 40 African countries have signed a deal to create one of the world's largest free trade blocs, promising to bring prosperity to more than 1.2 billion people.

But some of the continent's biggest economies, including Nigeria and South Africa, have so far refused to join. And with more than 80% of African trade currently done outside the continent, what impact will the new deal actually have in Africa?

Some people on the streets of Kampala, Uganda, tell us they fear increased competition from neighbouring Kenya, and we ask Tonye Cole, billionaire co-founder of power and infrastructure giant Sahara Group, why his native Nigeria has decided not to take part.

Plus, we hear words of optimism from Ghana's trade minister, Alan Kyerematen, and Arancha González, executive director of the International Trade Centre.

With US President Donald Trump threatening to impose more sanctions, Iran remains frozen out of much the international financial system despite the 2015 nuclear weapons deal.

Sanctions lawyer Nigel Kushner explains why most international banks still steer clear of Iran, despite the lifting of sanctions, plus Ellie Geranmayeh of think-tank the European Council on Foreign Relations explains the latest diplomatic rumblings.

How do designers and advertisers get people's attention when there is so much competition online? And how do brands get around ad-blocker software?

Malaria continues to be one of the world's most destructive and widespread diseases, killing around 500,000 people each year, almost all of them in sub-Saharan Africa.

On World Malaria Day we hear how it continues to cripple communities and speak to one Kenyan woman who lost a child to the disease. Ethiopia's former health minister, Dr Kesete Admasu, explains how outbreaks can have far-reaching economic consequences, depriving farms and other businesses of workers at vital times. He also describes his current work at Roll Back Malaria, a foundation aiming to tackle the disease through genetically engineered mosquitoes and new vaccines.

Plus, Kenyan infectious disease specialist Dr Faith Osier tells us about another malaria vaccine she's working on, and we hear about the smartphone that could alert people when the breeds of mosquitoes that carry the disease are nearby.

India's women workers have joined the global #MeToo movement, but there are signs it may be backfiring, with some company bosses afraid to hire women, for fear of sexual harassment claims. And that could be one of the reasons why the number of women participating in the workforce in India has fallen from 36% to 24% over the last ten years. Rahul Tandon reports from Kalkota. Deepa Narayan, author of Chup - the Hindi word for quiet - shares insights gained by her team, after speaking to 600 women about their experiences of sexism at work and in wider Indian society. Professor Heather McGregor from Edinburgh Business School talks about office life since #MeToo and says, at the very least, people are more aware of what kind of behaviour is unacceptable and are more confident in reporting incidents of harassment.

Donald Trump says tariffs on Chinese goods are necessary to 'protect American workers'. So who in the US might benefit from this action? Tennessee voted overwhelmingly for Mr Trump in 2016 and does more trade with China than any other US state. We hear from farmers facing Chinese tariffs on soy bean exports and a manufacturer worried about rising US steel prices. We also hear from Shelbyville, once called 'pencil city', where one of the last US pencil factories says its business has been damaged by cheap Chinese imports for decades.

But is President Trump pointing the finger in the wrong direction when it comes to job losses? Calum Chace, author of The Economic Singularity and Our Jobless Future: An Essay on Artificial Intelligence and the Economic Singularity, says the decline in manufacturing has much more to do with automation than it does with China.

How much does your physical attractiveness affect your career prospects? And can the attention it draws be something of a mixed blessing?

Vishala Sri-Pathma hears from British barrister Dr Charlotte Proudman about her personal experiences in what is a very male dominated profession. But while good looks may help you land a job, does it make it harder to get on with your colleagues? Vishala speaks to Cary Cooper, professor of organisational psychology at Manchester University, body language expert Judi James, and headhunter John Purcell.
