I've been looking at an analog of "peak oil" the drought here in the west (california) and in southeast (georgia), to see if I could build a computer game and I've run into a brick wall of sorts (basically no formal education in economics).
I started off by thinking of the problem of peak oil as an supply/demand imbalance. Next I noted droughts are not a purely a physical phenomenon that can be defined by the weather. Rather, at its most essential level, drought is defined by the delicate balance between water supply and demand. Whenever human demands for water exceed the natural availability of water, the result is drought.
I've noticed in the news that as low as water supplies are in the Georgia area it has been business as usual (in that water still runs out of a tap), but I'll bet that if/when the water taps run dry there will be a non linear response.
In other words water which only costs a few pennies a liter if even that, is leveraged many times over to create products that can be sold for an order of magnitude more. Coke for example might have to shut down production lines, which is a bad thing for the local economy. There is also a cascading effect, for example if Coke based in Georgia cannot make the syrup because its plant had to shut down, this could have an adverse effect on global production.
In general I'm betting the economic pie shrinks dramatically when a basic building block (such as water or oil) of an economy suddenly becomes hard to obtain.
I'm thinking a vulture investor would be able to make lots of money shorting stocks (like coke) located in the area that is experiencing shortages. But I'm thinking the money made in the stock or commodity market is orders of magnitude less than the money created by an economy that is operating normally, producing products for sale to a global market.
As it stands, even with supplies of water running low, the market here in the west and in the south east has not re-priced water to reflect its scarcity. From what I understand of economic theory, if water were more expensive then two things would happen: demand would go down and the water that was being used would be used much more efficently. I also think if the market set the price for water to refect its scarcity, then the water crisis would not be as big a problem.
So my first economic questions are: does this train of thought have any holes in its logic? Second what would you conside the best way to distribute the remaining water? Would you introduce a system of rationing system? Would you try and reprice water to reflect its scarcity, with something like a consumption tax? Or do you have another alternative that I have not mentioned.
PART II
From what I’ve seen of traditional economic models, they assume there are no boundary conditions or upper limits. In other words if the cost of a product is lowered, traditional economics suggest that demand for that product would go up until the market is saturated.
Let's look at popular product like the iPod for example.
When Apple makes an iPod they can produce every single component in their iProduct: from the small LCD screen, to the RAM chips and they could put everything in an injected plastic case. Since Apple can make every single component in an iPod, the market would expand the market until it is saturated. In other words, every single person on the planet earth all 6 billion plus of us would have the opportunity to buy an iPod, because traditional economic models suggest that as more iPods are made the cost would go down.
My second set of economic questions revolve around the the idea of limits, as in a limit found in basic calculus. Does the idea of a limit exist in economics?
What I'm thinking about might be better illustrated if I continue on with the iPod example.
Lets suppose, LCD screen were a non-renewable natural resource and suppose there were only 100 million of them on the planet. In this case Apple would be a happy company and the stock price would corresponding go up, while there was an a supply of LCD screens they could get their get hands on. As time moves forward the limited supply of LCD screens would get used up, while at the same time more people would become aware of the iPod and want to own one. Starting to get the point, as demand for the iPod grows there would be a limit of 100 million iProducts that Apple or any other company could built.
When the 100th million iProduct was built, a person lucky enough to have an existing iPod would be able to sell it for more than they paid for it (this is because it is now a rare item that has a demand and economics tells us when supply goes down, the price goes up). At this time anyone with an iProduct would also have to guard it carefully because some young punk or a street gang might want to steal it. As for the company, after they built and sold the 100th million iProduct, the price of Apple stock would tank because they no longer could build and sell any iProduct with an LCD screen. If Apple or any other company could not find a replacement for an LCD screen, those companies would cease to exist...
Business or economics as usual to me means people assume that we have a limitless supply of basic stuff like water and oil.
What few people seem to appreciate is something the Apollo astronauts saw when they looked down on the planet earth from space.
A person looking down from the void of space would see a planet and would realize that there are limits, huge as they may be, on natural resources. While a person standing on the surface of the earth might be fooled into thinking natural resources are limitless because that is all they can see.
I understand a big business player such as the oil or the auto industry, has a vested interest in keeping up their economic advantage. But a big business player trying to keep their economic advantage, forces an unsustainable economic equilibrium point and this in my mind creates an economic bubble which in the long run is not sustainable.
From what I've been reading there is a long history of economic bubbles that eventually pop: the from the "Tulip and Bulb Craze" from 1634 to 1637 in Holland to the latest subprime real estate bubble that went on from 2002 to 2006 in the United States and in many other parts of the world.
I'm thinking just like an economic bubble if we ignore the natural resource demand imbalance for too long, there eventually will be pop (or put another way, bad shit will happen to lots of people).
So how do you model something with a limit in economics? What economic steps would you take to try and prevent a drought? I'm guessing observations of what happens in a drought model have some relevance needed to address problems associated with peak oil.
