Planetary limits, social needs and economics for the anthropocene – oecd observer electricity and circuits physics

################

All economic activity must obey the 9gag memes laws of physics and ecology. It is impossible to create something from nothing: every physical thing an economy produces is the transformation of raw materials provided by our finite planet. All economic production also requires energy, over 80% of which is provided by finite fossil fuels. Burning them generates waste, greenhouse gases and other pollutants. Moreover, all economic products wear out, break down or fall apart.

It is also impossible to create nothing out of something: the economy transforms raw materials and energy into economic products and returns them to the ecosystem as waste. A law of ecology is that everything is connected to everything else, so when we transform raw materials and energy into economic products and waste, we inevitably degrade the ecosystems upon which all life depends. Furthermore, ecosystems are subject to thresholds beyond which a small change in human activity can cause catastrophic and potentially irreversible ecological outcomes. We cannot accurately predict where those thresholds lie, or what lies beyond them. But we do know that to maintain healthy ecosystems while ensuring that people’s basic needs are met, those thresholds must be respected.

The trouble is, current rates of resource extraction and waste emissions are changing ecological functions and geochemical processes so rapidly that many scientists claim we have entered a new geological epoch–the Anthropocene– in which we run growing risk of crossing these ecological thresholds (see for instance, Steffen et al., 2015). Meanwhile, nearly a billion people are still chronically malnourished. We need a new economic system capable of meeting basic needs without exceeding planetary boundaries.

Can the market economy meet this challenge? The strengths of markets are that, under certain conditions, they maximise gas constant for air the monetary value of production and consumption as determined by the subjective preferences and free choices of individuals, and incentivise innovation. Unfortunately, for the challenge of remaining within planetary boundaries, markets are unlikely to achieve these outcomes, while for the challenge of meeting basic needs, their desirability is questionable. These claims require elaboration.

The most obvious problem is that many essential ecological functions, such as climate stability, cannot be owned. Markets therefore ignore their values, treating them as “externalities”, and will produce long past the point where the ecological costs of additional output exceed the market benefits. Individuals cannot choose how much to consume. For this reason, decisions to bolster ecosystem resilience must be collective.

Another serious problem with markets is that they weight preferences by purchasing power, favouring the whims of the rich over the needs of the poor. During electricity physics formulas the food crises of 2007-08 and 2011-12, the prices of staple grains doubled in response to small decreases in supply. In countries consuming over 3 500 calories per person per day, where the marginal utility of eating more food is zero or negative, our research found that consumption remained stable and people continued to throw away some 30-40% of the food they purchased. In countries where people were already consuming too little to meet basic needs, they cut their consumption even further, exacerbating already high levels of malnutrition and increasing political unrest. If our goal is to maximise monetary value, then it is more efficient to allocate a loaf of bread to a wealthy, possibly overfed Western consumer who throws a third of it away, rather than to a destitute African woman desperate to feed her starving children simply because the former can pay more. Ironically, a small reduction in the supply of essential resources causes their price, and hence the revenue they generate, to skyrocket, thus boosting GDP.

This perverse outcome raises serious alarms about internalising ecological costs into market prices as a solution to planetary boundaries–it would force the greatest sacrifices from those who contributed the least to causing the problems. If we are to use a pricing policy, prices should reflect both ecological and humanitarian costs: an appropriate price signal should make it vastly more expensive electricity trading jobs to buy fossil fuels for a private jet than for the satisfaction of basic needs such as food, water and shelter.

Markets may also be poorly designed for stimulating appropriate innovations at lowest cost. The profit motive provides little incentive for innovations that meet the needs of the poor, who have negligible purchasing power. In a classic example, drug companies halted production of the drug called eflornithine to cure African sleeping sickness because it made no profit, but continued to market the same compound in wealthy countries to slow the growth of unwanted facial hair.

Market incentives for innovation also require patents, which raise the cost of using existing information and slow the rate of scientific advance, as several researchers have shown. This is hardly the way to address pressing climate change. Furthermore, once a green technology has been developed, its social value is maximised when it is made freely available to all. If society developed clean, dependable and inexpensive solar energy, it would be counterproductive to limit use to those who could pay monopoly prices, while leaving others to burn coal. It is true that patents last only 20 years and then become part of the public domain, but can we afford to delay the widespread adoption of green technologies for that long?

Competitive markets worked well for a fossil fuel economy far from planetary boundaries. Now however, the physical boundaries of the planet compel us to make gas house edwards a transition to a zero-carbon, solar energy future. Countries need not compete for solar energy, since one country’s use leaves no less for others and technological innovations for capturing solar energy improve through sharing. The maximisation of monetary value largely excludes the poor, and unbridled economic growth exacerbates climate change. This is why governments must act together, which is what the UN climate change summit in Paris is about.

New approaches are needed. One would be for the richest countries to fund a global research effort into green technologies–especially alternative energy–with results made freely available to all, on the condition that any improvements are also open access. Open source software and the Internet have used this approach to unleash innovations. This “sharing economy” approach could stimulate the conditions of trust and reciprocity required to develop co-operative solutions to other global problems. Another would be to ensure that basic needs are met before selling essential resources to the highest bidder. We cannot simply assume that markets are always best.

An economics for the Anthropocene must be grounded in science but guided by moral values. Together, we must first decide on the socially, morally and psychologically desirable ends of economic activity–perhaps using the UN’s Sustainable Development Goals as a start–and then assess how to achieve them gas lighting urban dictionary. Only then can we determine what economic institutions will meet our goals.
