BREAKING NEWS
The Royal Swedish Academy of Sciences has decided to award the 2021 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel with one half to David Card “for his empirical contributions to labour economics” and the other half jointly to Joshua D. Angrist and Guido W. Imbens “for their methodological contributions to the analysis of causal relationships.”

This year’s laureates – David Card, Joshua Angrist and Guido Imbens – have provided us with new insights about the labour market and shown what conclusions about cause and effect can be drawn from natural experiments. Their approach has spread to other fields and revolutionised empirical research.

Many of the big questions in the social sciences deal with cause and effect. How does immigration affect pay and employment levels? How does a longer education affect someone’s future income? These questions are difficult to answer because we have nothing to use as a comparison. We do not know what would have happened if there had been less immigration or if that person had not continued studying.

However, this year’s laureates have shown that it is possible to answer these and similar questions using natural experiments. The key is to use situations in which chance events or policy changes result in groups of people being treated differently, in a way that resembles clinical trials in medicine.

Using natural experiments, David Card has analysed the labour market effects of minimum wages, immigration and education. His studies from the early 1990s challenged conventional wisdom, leading to new analyses and addi¬tional insights. The results showed, among other things, that increasing the minimum wage does not necessarily lead to fewer jobs. We now know that the incomes of people who were born in a country can benefit from new immi-gration, while people who immigrated at an earlier time risk being negatively affected. We have also realised that resources in schools are far more important for students’ future labour market success than was previously thought.

Data from a natural experiment are difficult to interpret, however. For example, extending compulsory education by a year for one group of students (but not another) will not affect everyone in that group in the same way. Some students would have kept studying anyway and, for them, the value of education is often not representative of the entire group. So, is it even possible to draw any conclusions about the effect of an extra year in school? In the mid-1990s, Joshua Angrist and Guido Imbens solved this methodological problem, demonstrating how precise conclusions about cause and effect can be drawn from natural experiments.

BREAKING NEWS
The Norwegian Nobel Committee has decided to award the Nobel Peace Prize for 2021 to Maria Ressa and Dmitry Muratov for their efforts to safeguard freedom of expression, which is a precondition for democracy and lasting peace. Ms Ressa and Mr Muratov are receiving the peace prize for their courageous fight for freedom of expression in the Philippines and Russia. At the same time, they are representatives of all journalists who stand up for this ideal in a world in which democracy and freedom of the press face increasingly adverse conditions.

Maria Ressa uses freedom of expression to expose abuse of power, use of violence and growing authoritarianism in her native country, the Philippines. In 2012, she co-founded Rappler, a digital media company for investigative journalism, which she still heads. As a journalist and the Rappler’s CEO, Ressa has shown herself to be a fearless defender of freedom of expression. Rappler has focused critical attention on the Duterte regime’s controversial, murderous anti-drug campaign. The number of deaths is so high that the campaign resembles a war waged against the country’s own population. Ms Ressa and Rappler have also documented how social media is being used to spread fake news, harass opponents and manipulate public discourse.

Dmitry Andreyevich Muratov has for decades defended freedom of speech in Russia under increasingly challenging conditions. In 1993, he was one of the founders of the independent newspaper Novaja Gazeta. Since 1995 he has been the newspaper’s editor-in-chief for a total of 24 years. Novaja Gazeta is the most independent newspaper in Russia today, with a fundamentally critical attitude towards power. The newspaper’s fact-based journalism and professional integrity have made it an important source of information on censurable aspects of Russian society rarely mentioned by other media. Since its start-up in 1993, Novaja Gazeta has published critical articles on subjects ranging from corruption, police violence, unlawful arrests, electoral fraud and ”troll factories” to the use of Russian military forces both within and outside Russia.

Novaja Gazeta’s opponents have responded with harassment, threats, violence and murder. Since the newspaper’s start, six of its journalists have been killed, including Anna Politkovskaja who wrote revealing articles on the war in Chechnya. Despite the killings and threats, editor-in-chief Muratov has refused to abandon the newspaper’s independent policy. He has consistently defended the right of journalists to write anything they want about whatever they want, as long as they comply with the professional and ethical standards of journalism.

Free, independent and fact-based journalism serves to protect against abuse of power, lies and war propaganda. The Norwegian Nobel Committee is convinced that freedom of expression and freedom of information help to ensure an informed public. These rights are crucial prerequisites for democracy and protect against war and conflict. The award of the Nobel Peace Prize to Maria Ressa and Dmitry Muratov is intended to underscore the importance of protecting and defending these fundamental rights.

Without freedom of expression and freedom of the press, it will be difficult to successfully promote fraternity between nations, disarmament and a better world order to succeed in our time. This year’s award of the Nobel Peace Prize is therefore firmly anchored in the provisions of Alfred Nobel’s will.

The Royal Swedish Academy of Sciences has decided to award the 2021 Nobel Prize in Chemistry to Benjamin List and David W.C. MacMillan “for the development of asymmetric organocatalysis.”

Building molecules is a difficult art. Benjamin List and David MacMillan are awarded the Nobel Prize in Chemistry 2021 for their development of a precise new tool for molecular construction: organocatalysis. This has had a great impact on pharmaceutical research, and has made chemistry greener.

Many research areas and industries are dependent on chemists’ ability to construct molecules that can form elastic and durable materials, store energy in batteries or inhibit the progression of diseases. This work requires catalysts, which are substances that control and accelerate chemical reactions, without becoming part of the final product. For example, catalysts in cars transform toxic substances in exhaust fumes to harmless molecules. Our bodies also contain thousands of catalysts in the form of enzymes, which chisel out the molecules necessary for life.

Catalysts are thus fundamental tools for chemists, but researchers long believed that there were, in principle, just two types of catalysts available: metals and enzymes. Benjamin List and David MacMillan are awarded the Nobel Prize in Chemistry 2021 because in 2000 they, independent of each other, developed a third type of catalysis. It is called asymmetric organocatalysis and builds upon small organic molecules.

The rapid expansion in the use of organic catalysts is primarily due to their ability to drive asymmetric catalysis. When molecules are being built, situations often occur where two different molecules can form, which – just like our hands – are each other’s mirror image. Chemists will often only want one of these, particularly when producing pharmaceuticals.

Organocatalysis has developed at an astounding speed since 2000. Benjamin List and David MacMillan remain leaders in the field, and have shown that organic catalysts can be used to drive multitudes of chemical reactions. Using these reactions, researchers can now more efficiently construct anything from new pharmaceuticals to molecules that can capture light in solar cells. In this way, organocatalysts are bringing the greatest benefit to humankind.
