Paul Stevens 08 June 2016

In 2014, after more than a decade of a booming oil market, oil prices collapsed. In this video, Paul Stevens discusses the effects of the super cycle for oil-exporting countries. The higher oil prices destroyed demand, leading to over-supply and a fall in prices. As a consequence, oil-exporting countries had difficulties in meeting budget expenditures and needed to diversify their economies. This video was shot during the International Growth Centre’s annual conference held in London in June 2016.

If an economist selects the wrong model to study a question, the results are also likely to be wrong. In this video, Bruce Hansen talks to Soumaya Keynes about how model selection and combination can be used for forecasting with small error. Model combination methods are suited for forecasting and policy evaluation. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.

Are criminals lacking in moral motivation? In this video, Alexander Cappelen and Bertil Tungodden conduct an experiment in order to understand if prisoners differ from other people when it comes to sharing money. On average, prisoners share as much as others when confronted to the same situations. Their study has implications for the reintegration of criminals into society. This video was recorded at the Choice Lab, Norwegian School of Economics, in Bergen.

Haiqing Xu 01 June 2016

Econometrics is a big part of economics. In this video, Haiqing Xu presents his paper for which he won the 2014 Sargan Econometrics Prize. He presents a game theoretical model that can be used to analyse firms’ strategic behaviour and to study social interactions. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.

Pedro Gomes 30 May 2016

There are sometimes large wage disparities between the private and public sector. In this video, Pedro Gomes presents his research on how to set wages in the public sector. The study focuses on finding principles that can help policymakers design policies for public employment. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.

Christian Hansen 27 May 2016

Big data is changing economics and the way causal relationships are studied. In this video, Christian Hansen and Soumaya Keynes discuss the importance of big data for econometrics. Big data offers a lot of information and it is easier to draw policy lessons. It also gives more flexibility without forcing researchers to impose control variables, allowing more reliable conclusions to be obtained. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.

What happens in the brain when something is fair or unfair? In this video, Alexander Cappelen and Bertil Tungodden present their research on the effects of fairness on our brains. Using fMRI technology, the neuroeconomics study shows that the brain reacts to unfairness. Income inequalities are perceived as fair if they reflect different work contributions. This video was recorded at the Choice Lab, Norwegian School of Economics, in Bergen.

Erick Gong 25 May 2016

Individuals getting tested for HIV are expected to reduce their risky sexual behaviour. In this video, Erick Gong discusses the impact of HIV testing and expectations about the test results on risky sexual behaviour. The number of people being HIV tested is increasing, and understanding how individuals react to is important to adapt policies to treat the virus. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.

Esther Duflo 23 May 2016

Randomised controlled trials create comparable groups which are subject to different treatments. The results of the trial allow us to understand the impact of a particular intervention. In this video, Esther Duflo discusses how randomised controlled trials can be used to inform policymakers. Experimenting with policies under different contexts could help build more effective policies, especially in developing countries. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.

Giovanni Mastrobuoni 20 May 2016

Education usually has a protective effect – people with higher levels of education are less likely to start criminal activities. In this video, Giovanni Mastrobuoni discusses the benefits of education on members of the Italian-American Mafia. Although the nature of the business is illegal, those involved in business-related crimes (loan sharking, drug dealing) are those who gain the most from an extra year in school. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.
