On Monday, 4 December 2017, I am going to present work in progress tentatively entitled “Mitigation strategies when faced with the threat of solar radiation management”. This is joint work with Fabien Prieur (University of Nanterre) and Martin Quaas (University of Kiel). The presentation will be held in Paris School of Economics, 48 bd Jourdan, near metro stop Porte d’Orleans, from 12.00-13.30, in its weekly seminar series “Environnement et Régulation” organized by Hélène Ollivier.

A proper working paper is coming out soon, stay tuned! If you want to know what the paper is going to be about, come and listen.


There is of course one supercompany that always makes the news: Monsanto. It is not surprising. After all, Monsanto is in a tough business and there is sufficient personal reason for them to ignore scientific data in order to maximize their own profits. So what is going on?

I have recently come across this new working paper by Timothy Besley and Avinash Dixit. They develop a theoretical model in order to understand how much consumption society should give up in order to mitigate catastrophic risk. I am not really happy about something there.

I am one of the candidates for the municipality elections in Niederanven that are to be held on the 8th of October 2017. I am running for the LSAP and our programme can be downloaded here. So who am I, why am I a candidate and what are my main objectives?

I am tired of being quiet. For weeks now I have been reading about Trump, le Pen, Brexit, ignorant politicians who breed hatred, racism, about election campaigns that foster right-wing views and self-interest politicians. I have been reading about how international cooperations are blamed for poor national decision taking, and I have been reading about how countries can become great again if only they look at their self-interest at the expense of everyone else.

I wonder how one can be so stupid as to confuse money with greatness. The US was not accepted as a world leader because it was rich, but because it was open to everyone, provided opportunities regardless of gender, color and origin. The US, to a large part, was a haven for those forgotten souls out of other parts of the world that tried to find a new and good life. These ideals seems to be vanishing, and both dumb leaders, populism and uninformed press play a major role. Liberté, égalité and fraternité are those values that are supposed to represent the French, but nearly electing someone like le Pen as their leader makes one seriously doubt whether France will in future continue to be represented by those important three words.

And I have kept quiet. I have kept quiet as I believed that it is a mistake to provide a further platform to these idiots out there that have been elected to represent the apparent interests of voters. It is, however, becoming more and more clear that these `interests’ will eventually only lead to seggregation, violence, further hatred, wars, conflicts, inequality and further poverty (c.f. Trumps views on trade or the dumb Brexit vote).

Yet being quiet in the face of these unfortunate, self-interested, dumb and ignorant political decision-takers only gives them more attention than they deserve. I fully believe that the only choice that we have to minimize their influence is to show how their decisions are frankly out of touch with reality, out of their voters’ interests, and harm the poor, the forgotten, the international relations and the future of the country that they are supposed to represent. Trump is bashing those values that made the US a great country, and his “make America great again” slogan has, as of now, only made his own pockets great again. It is unfortunate that there are still many people out there who believe in his views but it is also my sincere opinion that, with enough information and effort, these people will come to see that there are alternatives without violence and hatred.

So what can we do?

I believe that everyone needs to question very carefully what is written. Information is the key. If you become scared of immigrants, Christians, Moslems or Buddhists, then go and meet some. Try to find out for yourself. Don’t just take the examples from a couple of stories as the general rule. Learn for yourself. Yes it takes time. But every bit of hatred that you feel the need to show to someone else is worth a couple of minutes of your time in order to see whether this hatred is necessary and useful.

Hatred, violence, and radical politicial positions that are against some indefensive minority will not make anyone better off. We all know that in our hearts. Some of us may be angry. Many of us feel that our lives could be better. Few us honestly believe that their situation is due to immigrants or could be improved through voting for some radical parties.

We hence need to make sure that there is more redistribution in society towards the poor and forgotten. No one needs a couple of millions on the bank account. No one truly needs a Ferrari or Hermes bag or the own private jet. Trump’s approach to politics however does promote exactly this. There is no way that someone like him can be allowed to complete his presidential term, or even have a second one. Similarly, if we do not want to have wars in Europe again, and if we want to promote the interests of the poor and those that need their interests to be represented, then we must fight those views that are against equality, society and a good life together. Being quiet is a mistake. I understood this now.

This is a call to everyone in society to stand up again, to cooperate, to promote values that help achieve common goals and united interests. Don’t be quiet.
