Blog: Economics in Action

Economics is a subject in its own right but it is well known for incorporating other disciplines including sociology, philosophy, politics and maths. Maths in particular is integral to economics.

For some reason maths isn’t often seen as the fascinating subject it is. It allows us to build bridges, measure stars, play hopscotch, make cars, cook; the list seems endless. Economics uses maths to frame and test its theories.

The Radio 4 show More or Less which “is devoted to the powerful, sometimes beautiful, often abused but ever ubiquitous world of numbers” asked well-known guests and contributors to say why they love numbers. The short films include Konnie Huq, Vince Cable and Rick Edwards.

In the last of our podcasts supporting the Royal Economic Society Conference 2008, Romesh Vaitilingam talks to Jacques Melitz about how increased spending on Social Security benefits may help to keep us out of recession.

Listen to the interview

Increased public spending on incapacity benefits, health and pensions can all help the economy recover in a slowdown or recession. That is one of the findings of new research by Professors Julia Darby and Jacques Melitz presented at the Royal Economic Society’s 2008 annual conference.

In a slowdown some policies help the economy recover automatically. A recession increases the total amount spent on unemployment benefit (as more people are claiming it) and reduces the total tax take (as people’s tax bills drop). This helps to stimulate the economy without any active government intervention.

The report finds that these automatic stabilisers play an even greater role smoothing the business cycle than previously thought. This is because programmes such as incapacity benefit, pensions and health spending all act as such stabilisers as well.

In the latest of out podcasts supporting the Royal Economic Society Conference 2008, Romesh Vaitilingam talks to Karl Taylor about how socially active parents choose to be and the effect that can have on their kids.

Listen to the interview

Parents who are active in various kinds of clubs “from sports to charities, from political parties to religious groups“ may raise the test scores of their children. That is the central finding of new research by Professor Sarah Brown and Dr Karl Taylor presented at the Royal Economic Society’s 2008 annual conference.

The report uses data from the National Child Development Study, which has tracked the lives of a representative sample of the British public born in a single week in 1958. It finds that the test scores of children in reading, mathematics and vocabulary tests are positively related to their parents’ level of social participation.

In the latest of our podcasts supporting the Royal Economic Society Conference 2008 Romesh Vaitilingam talks to Dan Anderberg about some socio-economic analysis of the effects of the MMR controversy.

Listen to the interview

Highly educated parents responded more strongly to the controversial study linking the measles, mumps and rubella (MMR) vaccine to the development of autism in children. That is the central finding of new research by Professor Dan Anderberg and colleagues presented at the Royal Economic Society’s 2008 annual conference.

Whats more, the study finds, these parents were less likely to have their children vaccinated against other diseases after the controversy, not just MMR. Since there was never any suspicion of doubt about other vaccines, this may have put the health of their children at risk.

In the latest of our podcasts supporting the Royal Economic Society Conference 2008 Romesh Vaitilingam talks to Ben Lockwood about the effect of the European Single market on alcohol and tobacco taxes.

Listen to the interview

In the wake of Alistair Darlin’s swingeing increases on duty on alcohol in Wednesdays budget comes a new report examining why duty may not have been increased as much as governments would have liked and implying that these new duties may not raise as much revenue as the Chancellor is expecting.

The research by Giuseppe Migali and Ben Lockwood, presented at this Royal Economic Society’s 2008 annual conference, finds that the completion of the European Unions single market which removed all restrictions on trade in goods between member countries meant that the UK government has not been able to raise alcohol and tobacco duty as much as it might like.

Crisis regulation may help avoid another Northern Rock style panic, according to research by Professors Shurojit Chatterji and Sayantan Ghosal presented at the Royal Economic Society’s 2008 annual conference.

Listen to the interview

But the authorities should not always aim to prevent bank runs on the contrary, when regulators cannot monitor banks and fine those that are behaving irresponsibly, the possibility of bank runs is needed to prevent banks from lending irresponsibly in the first place.

In September 2007, Northern Rock suffered the first bank run on a British bank in over a century. The spectacle of depositors queuing up in front of the high street branches of the Northern Rock has prompted much commentary on the stability of the financial systems and the global consequences of the subprime crisis in the United States.

In the first of a series of interviews with economics researchers at the Royal Economic Society Conference 2008, Romesh Vaitilingam talks to Karen Croxson about Promotional Piracy: Why some media and software companies turn a blind eye to illegal downloads.

Listen to the interview

Some providers of digital products, such as software, music and film, may turn a blind eye to or even encourage piracy of their goods, according to new research by Karen Croxson presented at the Royal Economic Society’s 2008 annual conference. They do this because while piracy may harm sales, it can also serve to provide free marketing, helping to create buzz about a product.

The most high profile example of buzz is the Arctic Monkeys, a British music group, which distributed its initial songs freely online. But firms in other industries may benefit from the same effect. Makers of office software such as Microsoft may enjoy a net benefit from piracy: business users are unlikely to copy the product, and others who copy it would not have bought it anyway. Thus, the main effect of piracy is extra cheap promotion, and this in turn may explain why copy protection applied to office software is relatively weak.

In the latest of a series of interviews from the Royal Economic Society Conference 2007, Romesh Vaitilingam talks to Emma Tominey about the effect of smoking during pregnancy.

Listen to the interview

Mothers who smoke during pregnancy will have smaller babies. But much of the harm is due to unobservable traits of the mother. If mums stub it out by the time they are five months pregnant, the damage is as good as undone.

At the same time, the lasting harm to babies is greatest if the mothers have low education. So a much more holistic approach to improving child health in pregnancy is needed to help thousands of children break out of the poverty trap.

These are the conclusions of extensive new research by Emma Tominey, presented to the Royal Economic Society’s 2007 annual conference at the University of Warwick, 11-13 April. (more…)

In the latest of a series of interviews from the Royal Economic Society Conference 2007, Romesh Vaitilingam talks to Victoria Prowse about the ‘Part-time Occupational Penalty’ for UK women.

Listen to the interview

No matter what qualifications they have or how big their family is, British women face a substantial occupational penalty if they work part-time. That is the central finding of new research by Victoria Prowse, presented to the Royal Economic Society’s 2007 annual conference at the University of Warwick. (more…)

In the latest of a series of interviews from the Royal Economic Society Conference 2007, Romesh Vaitilingam talks to James Walker about the pay of UK academics.

Listen to the interview

Academics are underpaid and overworked compared with other graduate professions and this is likely to have consequences for the quality of UK degrees. That is the conclusion of new research by James Walker and colleagues, presented to the Royal Economic Society’s 2007 annual conference at the University of Warwick. (more…)
