The Nobel prize-winning economist and professor of psychology Daniel Kahneman focuses his latest research on the high cost of inconsistent decision making. In Noise, co-authored with Oliver Sibony and Cass R Sunstein, he looks at why humans can be so unreliable, and what can be done about it. He tells Andrew Marr that people working in the same job often make wildly different judgements, influenced by factors like their current mood, when they last ate, even the weather. He argues that ‘noise’ is distinct from bias and has been neglected by organisations and businesses.

Gillian Tett is editor-at-large for the Financial Times and is also focused on transforming the world of business. But whereas Kahneman uses the methods of psychology, Tett argues for anthropology. For over a century anthropologists have immersed themselves in unfamiliar cultures, studying the hidden rituals at play. In her book Anthro-Vision, Tett uses similar techniques to reveal the underlying structures and human behaviour in our modern world – from Amazon warehouses to Silicon Valley to City trading floors.

Ann Cairns is the executive vice chair of Mastercard, which has hundreds of offices worldwide.

Cairns started out as a research scientist before developing an interest in offshore engineering, becoming the first woman qualified to work offshore in Britain. She moved into banking in the late 1980s and joined Mastercard in 2011.

The Chinese government is pleading for young people to have more babies. On Business Weekly we ask whether this new “three-child” policy will help reverse the ageing population. You can’t send babies out to work, so does the nation face a demographic time bomb? Plus, the growing industry of forensic genealogy is cracking decades old murder cases. Our reporter asks how much privacy do we have to surrender - and is it worth it? And as the US marks 100 years since the Tulsa Race Massacre, we head to a more recent place of protest and trauma: Minneapolis. The president of the Federal Reserve of Minneapolis tells us he wants to do more to fight racism and inequality, but a black businesswoman from the city says she’s not seen many signs of equality. And is the boozy power lunch back? Business Weekly is produced by Matthew Davies and presented by Lucy Burton.

Mei Xu is a Chinese American entrepreneur who made it big in the US by setting up a global candle business. She grew up in Chairman Mao's communist China, but was educated at an elite school, where she learnt English with the aim of becoming a diplomat. That was until the pro-democracy, student protests of Tiananmen Square in 1989. After that she managed to get a passport out of China and went to the USA, where she set up her multi-million dollar business. What does her story tell us about the state of the American economy and the growth of China as an economic superpower?

The rise of electric vehicles could see traditional service stations closing across the planet over the next two decades, and replacing pumps with fast chargers is unlikely to save them.

Justin Rowlatt speaks to one entrepreneur hoping to profit from the rollout of EV chargers in every home and parking space, Erik Fairbairn of Pod Point. Meanwhile Isabelle Haigh, head of national control at the UK's National Grid, explains why she is confident they can meet the electricity demand from all these new vehicles.

Across the Atlantic, another entrepreneur - Sanjiv Patel of National Petroleum - says the writing is clearly on the wall for his chain of 25 gas stations in California - but maybe not for a while yet. But could he turn them into restaurants or use them to hold séances? That's the fate of one petrol station in Leeds that is now an arts centre. We hear from its owner, Jack Simpson.

In the US - but increasingly in other countries too - cold case murder, sexual assaults, and unidentified person cases once thought unsolvable are being cracked thanks to the proliferation of public genetic databases. But with this success come deep worries for our DNA data. Ivana Davidovic talks to Brett Williams, the CEO of Verogen - the owner of GEDMatch consumer DNA database - about their business decision to cooperate with the police, privacy concerns and new opportunities opening up in countries like Mexico and Vietnam. We also hear from Tina Franke, whose daughter Christine Franke was murdered in Florida in 2001. She speaks of her relief at the unexpected progress in the investigation after almost two decades. Professor Andrew MacLeod tells us about his project - in conjunction with King's College London - to harness forensic genealogy to identify perpetrators of sexual violence in the aid industry. And law professor Natalie Ram explains the pioneering legislation being brought in the US state of Maryland designed to regulate the industry much more tightly.

In Africa, malaria is far more widespread than Covid-19 - so what would it mean to African economies if it was eliminated? We speak to the man whose team in Oxford devloped an effective vaccine for the disease. Mice have overrun parts of Australia ruining crops and testing sanity. We learn about the effect this plague of rodents is having on the rural economy. We hear why Amazon has bought the iconic MGM Studios - and what it means for both Amazon customers and cinema lovers. Plus, our reporter heads to San Francisco to hear how the city’s Chinatown has coped with both Covid-19 and an increase in anti-Chinese race hate crime. As shops are boarded up and tourists stay away, what plans are there to rejuvenate this historic area? Business Weekly is presented by Lucy Burton and produced by Matthew Davies.

Not everyone can be special, so should we embrace our mediocrity?

In a programme first broadcast in August 2016, Manuela Saragosa investigates the appeal of being average. She talks to mediocrity advocates and bloggers Krista O'Reilly-Davi-Digui from Alberta in Canada, and Mark Manson in the US. But what happens when whole societies embrace mediocrity at the expense of excellence? Italian philosopher Gloria Origgi explains the concept of "kakonomics'" - the economics of being bad.

Will the craze for the cryptocurrency started as a joke end in tears? We delve into the world of Dogecoin and ask why people are investing and what the consequences might be.

Plus, Kevin Roose, a tech columnist with the New York Times explains why the last year of financial trials and tribulations have made cryptocurrencies attractive to some seeking to make a fortune. And David Gerard, a cryptocurrency sceptic and author of Attack of the 50ft Blockchain, tells us why he thinks the crypto boom will turn to a bust.

The International Energy Agency has added its voice to those calling for the end of fossil fuels. The dramatic intervention from the body which helps keep global oil supplies moving is music to the ears of many scientists and environmentalists. Shareholder activists too are pushing from within companies for an energy transition so we ask what the future looks like for the oil and gas sector. Why are some companies resisting the call to go green faster and harder? We’ll look at what happened to the autonomous driving revolution we were all promised. Are driverless cars ever going to be more than an experiment? The hospitality sector may be opening up across the world once more, but who is going to be waiting the tables and cooking the meals? Many staff who were laid off in the first wave of the pandemic have since found new jobs or even moved countries creating a huge staff shortage. And all work, no play? Our workplace commentator extols the virtues of a little play at work. Business Weekly is presented by Lucy Burton and produced by Clare Williamson. (Image:Oil field, Azerbaijan, Credit: BBC)
