Post-Growth, Credit, Interest and Money

As impressively (though unwittingly) shown by Francis Fukuyama, attempts to imagine the future of societies are likely to go wrong. Extrapolation of trends can well be a bad idea. On the other hand, some idea about what the future is to look like is needed when a major transformation of the society is to be attempted. The transformation towards a post-growth society is no exception here. It would be naive to expect an exacting outline of how a post-growth society is supposed to work, but it is important that those advocating it at least try to give answers to some inconvenient questions: what about productivity growth? Can universal basic income, supported by many in the degrowth movement, work? And what about the monetary and financial systems? The latter question has gained some attention recently, and some argue that monetary factors might be a main obstacle for a post-growth society. Their arguments should get proper consideration if we do not want to choose the wrong transition “trajectory”, given path dependencies so common in socio-economic systems. Continue reading

What Do We Need Homo Oeconomicus For?

A few days ago, the celebrity among German economists, Hans Werner Sinn, published a short piece in the Süddeutsche Zeitung in which he defends economics against common and, according to him, mistaken criticisms. I won’t take issue with all 6 points he raised (invisible hand, ecology vs economics, Keynesianism vs neoclassical economics, competition, neoliberalism and homo oeconomicus), instead focusing on the last one. I had started writing a post on this anyway, so Sinn’s commentary comes just-in-time. The main question behind my criticism of Sinn’s presentation of the problem is: what do we need homo oeconomicus for? Continue reading

On Grasses, Transects and Statistics or Science Is a Mess

As an environmental economist, I in a sense build my work upon the work of others. So, its foundations are provided mainly by ecology and related (sub-)disciplines such as conservation biology. However, while diving into some aspects of these disciplines and interacting with biologists who actually work in the field, I have realised that in many cases, reality is much more messy than a superficial look into the respective literature might suggest.

Is Economics a Science? Dogmatic Economics Vs. Reflective Economics

A thought-provoking text that is somewhat complementary to my last post on the “monolith of economic theory“.

Fixing the Economists

The question asked in the title of this post is actually somewhat of a trick. It is a trick because it all depends upon how you define ‘science’. Often when people say that economics is a science what they are doing is defining ‘science’ in such a way that economics fits the bill. They can do this because there is no real, firm definition of ‘science’ that is widely held among philosophers of science, scientists or, most certainly, among economists (who are the most anti-intellectual of the three groups by far).

If we look at Wikipedia, for example, it gives a definition of science that is Popperian — despite the fact that Popper’s falsifiability criteria have been called into question since the 1960s.

Science (from Latin scientia, meaning “knowledge”) is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the…

The Seeming Monolith of Economic Theory As Taught at a Typical Economics Department

It is not only the world economy that is in crisis. The teaching of economics is in crisis too, and this crisis has consequences far beyond the university walls.

Thus begins the open letter of the International Student Initiative for Pluralism in Economics. As a former student of economics, I can only subscribe to that statement. Economics as a discipline (seemingly) does not offer much diversity of approaches. But economics curricula at most universities are even worse: they do not display even this bit of diversity that does exist. Indeed, this is one of the reasons why I started writing The Sceptical Economist more than four years ago. Continue reading

The Not-So-New Climate Economy Report

An alliance of the most influential global institutions, including the UN, World Bank, IMF and OECD, just issued a report of the Global Commission on the Economy and Climate, chaired by Felipe Calderón and Nicholas Stern. The report’s title is Better Growth, Better Climate: The New Climate Economy. In a nutshell, it says that not only is climate action compatible with economic growth, but the two may actually work as a positive feedback loop: more climate action leading to more growth, “smart” growth-spurring policies reducing emissions of greenhouse gases. By and large, the report does not contain any new arguments, as it is more of a synthesis of existing research. Alas, it is a synthesis of only a part of existing research, which can be already seen in the title: economic growth is a main objective along with the mitigation of climate change. You’ll vainly look for any reference to the degrowth and a-growth debates, and so the report, while valuable in some respects, reproduces many of the common errors of growth-enthusiasts.
