Ein Hauch von Ökonomik: leben und leben lassen

In der Wohngemeinschaft, in der Siedlung, am Campingplatz, im Hotel, im Restaurant, im Zug, im Park und im Hörsaal – überall treiben wir unser Unwesen. Wir, scheinliberale Spaßnudeln aus dem Team Yolo mit dem Codenamen Chillax – zu cool für gesellschaftliche Übereinkünfte, wenn letztere unserem Egotrip gerade nicht dienlich scheinen. Haben wir Lust auf ein wenig Krach nach Mitternacht, auf eine Zigarette am Esstisch und auf Lautsprechermusik im vollen Abteil, dann bilden wir uns ein Naturrecht darauf ein. Wagt jemand eine Beschwerde, zeigen wir uns höchst empört über den spießigen Versuch des Freiheits- und Rechteraubs: man möge sich doch entspannen, sich beruhigen, die Sache nicht so eng sehen – leben und leben lassen.

Das sagen ausgerechnet wir, die wir unruhig und engstirnig momentanen Impulsen folgen und konfrontative Situationen provozieren, anstatt diese zu entspannen. Wir, die wir uns das Recht herausnehmen, rücksichtslos in das Leben anderer einzugreifen, verwehren uns schon im nächsten Moment gegen regulative Interventionen und verkaufen es auch noch als Überzeugung.

Wehe, uns würde jemand früh morgens den Schlaf rauben. Wehe, jemand würde neben unserem Speiseteller ein Duftstäbchen entzünden. Wehe, zwei Sitze weiter würde jemand Schlagerlieder vor sich hin krächzen. Wehe, jemand wagt irgendetwas, das nicht unserer Präferenz entspricht. Asozial muss dieser jemand sein und natürlich spießig, wenn er überhaupt ein Leben hat. Denn wir haben ja eines und wissen daher, wie ein Leben auszusehen hat. Wir, gleichermaßen Zentrum der Welt und Maßstab aller Dinge. Oder doch bloß ewig im Stadium egozentrischer Kleinkinder, welche die Welt ausschließlich von der eigenen Position aus zu interpretieren im Stande sind?

Jedenfalls nicht ganz die Toleranz, die wir so gerne einfordern. Koordination, Kooperation und entsprechende Regeln sind eben komplex. Und kompliziert sein ist was für Stresser. Wir hingegen sind simpel. Kein langes Abwägen von gegenseitigen Abhängigkeiten und externen Effekten. Stattdessen finden Beurteilung und Sinnfrage bereits mit dem Abgleich des spontanen Eigeninteresses ihr Ende. Individualistisch, opportunistisch und teilweise bildungsresistent hinsichtlich empathischer und rationaler Entscheidungsfindung – ja, wir arbeiten hart am Ende der sozialen und liberalen Gesellschaft – zu entspannt, um leben zu lassen, was uns leben lässt?

On David D. Friedman’s view about climate change

This week David D. Friedman gave two talks at the University of Graz. The first has been on anarcho-capitalism and his proposal for a society organised without any form of public institution (cf. [1]). In his second talk Friedman argued why uncertainty in climate science denies any form of recommendation for climate mitigation and in particular for early action. In this blog post I will essentially focus on his second talk but give some conclusions why I think his proposal for anarcho-capitalism directly feeds into his ‘wait-and-see’ principle regarding climate change.

Argument I: What do we know – the bias of IPCC

What has been most striking to me was his argument regarding the credibility of climate change research. Currently the ‘best guess’ – to use his terminology – is represented by the Assessment Reports carried out by the Intergovernmental Panel on Climate Change (IPCC) which regularly publishes the latest state of knowledge. Friedman unhesitatingly dismissed the work of the climate science community because in his view the research is distorted towards negative externalities. But he even went further saying that climate science is biased due to the prejudice that climate change exclusively will trigger negative externalities. But as a matter of fact, this potential deficiency has led to increased attention by the scientific community in order to outweigh merits and demerits of a changing climate:

The IPCC research process [2]-[3] “multiple stages of review”

“comprehensive, objective and transparent assessment of the current state of knowledge”

“priority is given to peer-reviewed literature”

The IPCC selection of authors [3] authors are selected on the basis of their expertise [and their] detailed CVs”

“composition of author teams aims to reflect a range of scientific, technical and socio-economic views and backgrounds”

“author teams […] include a mix of authors from different regions and from developed and developing countries”

The IPCC AR5 report in figures [2] q.e.d.

Friedman did not even mention (least of all appreciate) this approach of doing peer-reviewed falsification analysis. Furthermore, he particularly challenged the robustness of climate models applied in the five assessment reports. Evidently, ALL MODELS ARE WRONG (see [4] for a nice recap “On mismatches between models and observations”). Friedman knows it, but everyone seriously doing research knows the deficiencies but also the merits of modelling. To continue, his argument was that the ex ante projections from the applied models in the first AR did not match with ex post empirical observations. Even if this argument would be correct (which is not, cf. [5, TFE.3, Figure 1, p. 64]) his claim regarding the misspecification of the AR1 models does not translate into the subliminal claim that improved models in AR2-5 are completely flawed.

To elaborate more on doing projection (not prediction) research by means of modelling, Friedman argued that in face of uncertainty we can never incorporate all potential effects (regardless of the challenge they are related to). The net effect of positive and negative externalities is unclear in the narrow approach of modelling. I totally agree on that but the implications of such a passive attitude towards the ability to actively follow a precautionary principle are devastating. If fate is the only determinant for future well-being, why are there so many efforts and vested interests in shaping its own prospects?

In the case of climate change the challenges ahead are higher by order of magnitudes especially since ‘tipping points’ can cause positive feedback effects additionally triggering forcing [6]. As Hansen [7] puts it: “wait and see and clean up the mess post facto, will not work […] because of inertial effects, warming already in the pipeline, and tipping points”. Hence, “[to avoid] the unmanageable and [to manage] the unavoidable” [8] certainly represents a more rational approach than Friedman’s proposal.

Argument II: From average homogeneity to heterogeneous distribution

Friedman then went on arguing that human species is not optimally adapted to weather conditions because humans are populated in various climate zones over the world. Obviously, there is a range of optimal or acceptable conditions but the point is that, again, passing lower or upper boundaries of this range can lead to severe impacts on humans [9]. A plausible response is migration as a form of adaptation which also Friedman highlighted. But in his argument he essentially disregards any influence to the adaptive capacity of individuals simply assuming homogeneity. He never mentioned one of the decisive points with regards to adaptive capacity which is: where are affected people located on the global cumulative curve of income and wealth.

Several times, Friedman pointed to the ‘marginal’ change of global average temperature, again neglecting the distribution of change among space and time. In its latest “Statement on the Status of the Global Climate” the World Meteorological Organisation documents that the global average temperature in 2016 has been 1.1°C above the pre-industrial level earmarking a novel record after the preceding record year of 2015 [10]. In Austria the temperature increase has even reached a 2°C increase in the same period investigated [11]. For some regions, the observed temperature increase is yet above this level [5, Figure SPM.1, p. 6]. And most strikingly is Friedman’s emphasis on ‘marginal’ or ‘slow’ change in temperatures. For the rate of increase since the beginning of the industrialization this is simply not true [5, Figure 5.7, p. 409].

The prospective impacts will vary in magnitude, direction, space and time [12-13]. But let’s focus a fortiori on a positive externality Friedman has been referring to. For the case of food security it is true that most crop yields could increase up to 20-30% [14]. But these numbers have been evaluated under controlled experiments in the laboratory. Where and when crop yield is expected to be increasing is again a question which Friedman did not further elaborate on. Additionally, there is evidence that the protein content of some crops decreases with higher temperatures [14]. Hence, distributional issues and implications are not within Friedman’s analytical approach. This is also reflected in his utilitarian and consequentialist view of the world: if the number of people dying from cold weather conditions decreases stronger due to global warming than the number of people dying from heat stress increases there is clearly a net benefit. Message to the individuals in the latter group: could you please stand up?

Argument III: Directed economic growth and path dependency

All the above makes the case for the complement of adaptation which is mitigation and in particular early action. It is true that at the moment many technological and behavioural changes complying with climate-neutrality are costly. But what Friedman essentially misses is that economic growth (and its associated benefits) not only has a rate but also a direction. For instance, the technologically driven cycle in the US originating in the ‘mission to the moon’ has been a political and social goal. Besides the development of rockets this mission-oriented approach has led to various kinds of state-funded offspring inventions and innovations ranging from telecommunication technologies, photovoltaics and so on [15].

Let me here bridge the gap back to Friedman’s first talk (and the blog post of Timon Scheuer) and then back again to climate change and the mission-oriented approach. In principle, his proposal for a stateless society – in which “private property, individual rights and voluntary co-operation” is solely brought about by bargaining between contract parties – is an interesting case to look at. In essence it is about completely decentralising the use of force or the threat of using force in order to enforce individual rights. A discussion of this proposal would fill several blog posts (again, cf. Timon Scheuer’s contribution). At the moment let me just argue that this proposal clearly feeds into his ‘wait and see’ principle. In his view, people are informed enough in order to react to changing social, economic and climate environments and, self-evidently, there exist ad hoc responses. But what about ‘tipping points’ and the associated irreversibility experienced post facto? Friedman’s anarcho-capitalist society reflected by self-interest at the micro scale and random walk at the macro scale is certainly not preparing in a way that the direction of change tackles the challenges ahead.

The Case of Anarchy, Case Closed: a comment on a talk by David Friedman.

“All human beings are born free and equal in dignity and rights”. At least as long as David Friedman’s dreams do not come true. In the anarcho-capitalist society he proposed in today’s talk rights are goods and services traded on markets. The rights you are born with are then those your parents are paying for. I invite you to think about the destiny of your dignity, if you are born in such a society without solvent and generous parents. It gives me the creeps just as David Friedman has done, when he indirectly preached against the first article of the Universal Declaration of Human Rights.

It was not only the lack of morality. It was also the lack of consistency. He may dream of a world without a government, but the system he sketched was not such. Publicly elected governments were just substituted by private ones individually selected on hypothetical markets. As if it was not bizarre enough that one has to purchase their basic rights just like one has to choose amongst hopefully affordable insurances, Friedman does not even hesitate to sketch the so-called law enforcement companies like organizations we know from Mafia films – sending strong men to protect their clients and punish their adversaries. We now know pretty well how ruling by private clans work out, from organized crime as well as from feudalism. We know that the “freedom of choice” often did not work out that well for those who tried to use it. We know about the economics of scale, network effects and corresponding concentration of power in cartels and monarchies. So, while I still have no clue how an anarcho-capitalist system should achieve a stable outcome in a world of externalities and asymmetric information, we can at least imagine the lack of liberty in a society where rights are distributed as unequally as property.

Money and bloodline already has enough influence on legislation, jurisdiction and execution. To me, giving up my one-vote-per-head democracy in favour of Friedman’s anarcho-capitalism seems just like the final resignation in favour of a sort of legitimised corruption. I cannot deny that governmental failure is obvious and the average voter knows too little about the true incentives, intentions and efforts of the politicians elected and electable. The transaction costs in favour of a well-informed decision, though, would not necessarily decrease only because the provider of law would be a private company instead of a public party. After all I am thankful for Friedman’s talk, which seems to be science fiction rather than scientific. Not only did he give insights into the theoretical and empirical shortcomings of libertarian thought, but he also encouraged me to stick to Winston Churchill’s quote: “democracy is the worst form of government, except for all the others.”
