Can we really call the environment a public good?

Public goods are defined as good which are non-rival (consuming them doesn't deplete other's ability to consume) and non-excludible (it is not viable to prevent access to this good).

I question whether a good such as the climate, or the air is really non-rival.

Consider air - we can see it having more than 2 uses. One people use to breath, or we can use it to dispose of pollution. Consuming air for breath doesn't change a factories ability to pollute, but a factories pollution does have the cost of air quality for people's breathing.

Just a quick thought:

The main driving force behind capitalism is that competition leads to efficiency yes? (There is also respect to principles such as freedom, independence etc, but anyway).

Essentially this means that it is required that there are atleast two suppliers in each market - in any monopoly it all breaks down - as is the case with natural monopolies (infrastructure - such as power lines, roading, water supply), where we use some form of government intervention.

This seems all very well, as most industries do have more than one supplier. eg most towns have more than one supermarket, more than one cafe, there's more than one auto factory etc

However - it maybe that this need to have more than one supplier has an opportunity cost of otherwise reaped scales of economies. ie. if the multiple suppliers were consolidated, there could be scales of economies to be reaped. If you think you have say 3 cafes, each able to supply 100 people, and each hiring 5 staff, if you consolidated them, you would probably cut down total staff. (of course it's nice for consumers to have choice etc, but this is purely on a economic/financial level).

Valuing the social/environmental impact of a project.

In environmental economics, when we do a cost benefit analysis of a proposed project we are typically valuing net economic or financial benefits vs environmental and social costs.

Let's take a fairly typical example - the construction of a Dam, Jonathan Harris frames the issue like this: "The project will have major economic benefits: hydro electric power, a stable water supply for irrigation, and flood control. It will also have negative effects: Farmland and wilflife habitat will be flooded, communites will ahve to relocate, and certain fish species may become extinct. The project may create new recreational opportunities for lake boating and fishing, but it will reduce scenic white water rating and hiking. ... Some costs and benefits are relatively easy to assess. ... But how can we put a dollar value on the social and ecological lossses that will result?".*

And so we do go on to try monetize the value of environmental damages - using various methods, such as people's willingness to pay to preserve, people's willingness to accept payment for damage, valuing equivelent substitutes for that environmental asset, or examining the value of other goods in relation to the environmental asset (Hedonic pricing - eg looking at the value of houses relative to the proximity of a nature reserve).
Certainly these methods can be usefull to an extent, though it becomes much harder or less reliable for values like 'spiritual value' or asthetics.

I argue, that we need to focus in more depth on the environmental and social benefits of the project. In the example of the dam, just taking the benefit of the additional electricity produced, we shouldn't stop our valuation at the amount of electricity it will produce. We should examine the longer term effects of that as well.

There are two scenarios that would arise from the additional electricity.
-Consumption of electricity remains the same - and less electricity is generated from other sources (eg coal fired plants).
-Consumption of electricity increases, used either in capital or end use consumption, (eg we could run another factory using the additional electricity, or consumers watch more TV, use air conditioning more etc).

This gives us a different method for weighing up the costs vs benefits. We can compare 'Is the flooding/relocation/extinction worth not burning that coal?'. We may be comparing apples and oranges here, and as economists it's nice to be able to put everything into a single perfectly relative $ value, but as we've seen, it's hard to monetize some values. At least this method gives us more perspective.

A thought experiment in capitalism.

Let's start with an even playing field.

Imagine you have two guys, Guy A, and Guy B, they both work the same job at a factory, earning $10,000 a year. After their basic living expenses (food, shelter) they have an disposable income of $1000 a year.

Guy B spends his money on booze. This has the flow on effect that he indirectly partially employs another guy to make the alcohol.
Guy A is disciplined and saves his money. He buys a taxi with his saved money. This has the flow on effect that he indirectly partially employs another guy to build a car.
Guy A (now a capitalist - as he owns some capital - the taxi), continues to work at the factory, but employs someone else to run the taxi.
Effectively here - Guy A and B's choice as to where to spend their money - determines other employment arrangements. Another person in the economy is going to be either a brewer or a car-builder, either going to produce capital or consumer goods - depending on how Guy A and B decide to spend their money. (We're assuming perfectly transmutable skills here).

The town they live in values the taxi service (ie they get more value out of it, than they pay to use it) - and thus the enterprise is a success - and Guy A manages to extract a profit (ie he charges people more than he pays the taxi driver). Guy A's taxi enterprise, on the face of it - seems like a win win situation. Guy A has some more income, and the town have a service that extract value from. Also - growth has occurred - another person has been employed due to Guy A's choice to invest in capital rather than consume.

So let's discuss this state of affairs.
The reason we say that Guy A should keep the additional profit, is not because he deserves it for his discipline (which really delves into moralistic type thinking), but rather we talk in terms of incentives. We allow people to keep the profits of their capitalistic ventures to motivate them to undertake those ventures.

The argument here is - if Guy A wasn't allowed to keep his profit, then he wouldn't bother saving his money, and would join Guy B drinking.
But let's question this - let's say the profit is then equally distributed through out the society. Guy A still receives additional benefit for his saving, both in his share of the profit, and the value of having a taxi service. Is this not incentive enough?

Let's consider how socialists and anarchists would approach this.
Ultimately - under a soviet style socialism - Guy A and Guy B wouldn't have a choice of what they spend their disposable income - (well - their choices would be restricted to a package that the socialist bureaucrat decides they are allowed to spend on).
In the capitalist example - the decision to have a guy working building a car - instead of brewing alcohol comes directly from Guy A's decision to spend his disposable income. Under socialism this would come from bureaucrat decision. Under capitalism - it is incentive that motivates allocation of resources , under socialism it is policy. This has the classic problems of socialism/government ownership - being rife with inefficiencies, vulnerability to corruption, and lack of direct incentive to make an efficient choice.

For anarchists... to me it seems that there is a lack of a model of how things would actually work. But it seems that the guy that can either work as a brewer or a carbuilder, would make the decision himself to build a car instead. Or the town collectively decides they want a taxi and the carbuilder/brewer will fill that demand. But it does leave me wondering what Guy A will do. Bear in mind here, that in order to get the car - consumption of alcohol must be sacrificed - how is Guy A incentivised to sacrifice his consumption? - Under socialism - he simply wouldn't be allocated the alcohol.

Universal Allowance.

This is an idea I've been thinking about since reading it in a Robert Heinlein novel.

The scheme is simply that everybody in the world receives a basic allowance, whether they have a job or not - that allows them to pay for food, and perhaps some accommodation. The scheme is paid for through existence tax arrangements. People then go on and get jobs to allow them to purchase luxury consumables, or to invest with.

The main rationale for the scheme relates to the fundamental premise of capitalist economics, that every actor is free, self interested, rational actor. I argue the the necessity to eat impinges on people's rationality and free decision making.

If people did not need to eat, the market arrangements the capitalist system comes to, would be far closer to the true efficient arrangement. For example, in the case of a factory worker work negotiating a wage with the factory owner: if the factory worker does not work - he starves, if the factory owner does not hire the worker - the product is isn't made, and the owner makes a loss. It seems obvious here, that the factory owner has far more wiggle room when it comes to negotiating - the owner can go for far more time without making a profit, than the worker can without eating. The natural result then, is that the worker will cave in before the owner will, so the agreed on wage will be lower than the true market wage.

The universal allowance then - allows the worker to hold out for the true market wage, which in turn produces further market efficiencies, ie distribution of resources to where they are truely valued, rather than concentration on resources at the natural advantage.

Re: Zeitgeist Orientation



What I have to say about this:
I identify 3 dynamics mentioned in this film.
1. Producers plan obsolescence to extract more profit.
2. Producers restrict production to extract more profit.
3. People are more motivated by 'for the love of it' than profit.

1. Planned obsolescence. Consumer responsibility is a key concept in economics, both the consumers and the producers make rational self interested decisions. So when it comes to issues like planned obsolescence or nasty chemicals in food, the consumer DOES have the choice not to buy the product. It's kind of a 'who blinks first' type situation. Eg. say the producer makes a product, and in his self interest builds planned obsolescence into, figuring he'll make more profit. To reflect the genuine situation, let's say the producers rival sees this, and also builds planned obsolescence into his products. The consumer, knowing that products are going to break down quickly, can choose to go without. If he gives in, the producers win, and were correct in their belief that it would make them more profit. However, the consumer can hold out, the producers suffer loss, and creates a market gap for a non-planned obsolescent good to enter the market. I argue- the reason so many planned obsolescent goods are on the market - is because the consumer simply doesn't care, they go for the cheapest item now, rather than the more expensive quality item.

2. Scarcity means more profit. Sure - scarcity means per unit the producer makes more profit. But the producer may make a greater total profit by selling more units at a lower profit margin. This is economics 101. Indeed this is how Chinese production firms do so well, they sell products at a low profit margin, but sell very large amounts*.

3. Innovators not motivated by profit. Sure your mad scientist may be more motivated by the love of science than the attraction of material wealth, or an author for the love of literature. But not all inventions produced for the love of whatever, are going to be valued by society. Should we publish every book every aspiring author produces? No! We should publish just the books that people are going to buy. By allowing profit to determine what is innovated, means that only the things that people value are innovated.

I suggest the reason so many shoddy products are on the market - is because we live in an oligarchy - producing a car or electronic good requires a lot of capital, and it's difficult for a new firm to raise the capital, to produce a rival good that isn't going to break down. The people that do have the capital to spare are part of the oligarchy and don't want to see a more competitive product on the market. But this is a problem of a concentration of resources, not of capitalism itself. (It could be argued that captialism is responsible for concentrating the resources? - But nah - it occurs under any regime). One potential solution is to have 'consumer unions' - where the members agree only to buy union approved products, and the union bargains on the consumer's behalf for quality merchandise, as well as being able to financially prop up firms that produce items that consumers want.

The problem is that consumers very much do live for today. Part of it is the necessity to consume (eg food) - but also consumers are far less organised that producers.

Dining out.

It makes economic sense that we don’t cook meals at home, but dine out regularly. This is what happens in South East Asia, and I will question why this is at the end.
Quite simply, it is better that 5 people cook for 50 people (ie chefs in a restuaruant cooking for 50 people over a night), than 25 people cooking for 50 people (1 partner cooking for the other, sharing flat cooking duties).
Not only will this saving on total man hours spent cooking, and doing dishes, and also things like electricity, water, and every house hold will not need the same pots, pans, plates, cutlery, and indeed ovens and full sized fridges. Also it may effectively eliminate the need for conventional supermarkets, and instead we would move toward more efficient wholesale warehouses. Effectively this will free up those factories to produce something we do value, or it simply means that we work less.
There are also spill over effects of increased sociability, and general life enjoyment.

I’ll try deal with the most obvious objection here, that the average worker cannot afford to dine out every night. Let’s make it clear that the economy wide cost of every bodies eating, is cheaper if with the dining out model, as demonstrated above, but the current reality is that even if it costs the average worker more time units to cook at home, it is a lot cheaper for him to cook at home.
I would argue that this is simply a reflection of inefficiently configured economy. However let’s consider one reason why this might be. It might be because we value the time of the chef much more than we value the time of the time of the chef much more than we value the time of worker, ie the time saved from not having to make dinner, not having to shop, not having to work to pay for pots, pans, fridge, oven, electricity, is not as valuable as the short time it takes for the chef to make the worker a meal. If that was the case, the worker would be better off getting himself into the dining industry, if he is happy to eat his own meals, then so will his fellow workers, but apparently he is being valued more.

Here is my model for how this society would operate.
Our worker (let’s call him Bob), get’s out of bed, does what ever exercises he likes to do in the morning, and then goes for breakfast. He has a smallish beer fridge in his kitchen, grabs some cereal some milk out the fridge, has breakfast. Perhaps he feels like a coffee, and this is actually a difficult area. It might actually be best that everybody has there own espresso machine.
First thing in the morning do you really feel like going outside to get a coffee from a professional? Making your own espresso isn’t that hard. And also - you really don’t feel like waiting in line. It’s alright once its 10oclock, you don’t mind so much waiting 5 minutes in a cafe for a professionally made coffee. So perhaps that’s one area where we still are diversified.
He goes to work, if he’s in an office he perhaps fills out an online order form and a office catering company brings the lunches around at lunch time. If he works in a factory, there is a similar system, or perhaps there is a restaurant type thing as part of the factory.
Bobs finished work now, perhaps he heads straight to a social club (there will be lots of these) with some friends where one can eat food, drink a beer, watch television. Or perhaps he just heads to a quiet favorite restaurant. Or perhaps he heads home, or participates in whatever other activities he does, and then heads out later into the street to the local restaurant on his street.

So why do countries like Japan and Korea have this model, and New Zealand or the United States not? The prime factors are probably the cost of the land, and the concentration of population. A higher population means more foot traffic and more customers. Also higher land prices put the cost of adding a kitchen to a house or apartment up, making sacrificing the kitchen and dining out a more attractive option. I think we value 'cooking for ourselves' - largely because it is seen as cheaper, which it is! Also, perhaps people don't value their time very highly - essentially seeing it as free. But this has also spawned into a kind of work ethic of cooking for yourself seen as valuable in itself. This is a mistake, and if the possibility arises for us to dine out at cheaper than it costs to cook at home, we should.
Also - I think people just don't consider it. In an urban context - a houseowner may do very well to consider saving money by building their house without a smaller kitchen, working out how much (how little) extra dining out instead would be.
