Discounts and pollution

Entropy law, in contrast to the common interest of the law, according to the financial system. Was taken into account, while the former specifies the physical path to wealth marches connection decrement (but never reaches) zero, and the amount of debt that the interest income from growth in March, allows a connection to an infinite path. The law has been the traditional financial system is contrary to the laws of physical systems.Our environment is very negative consequences of this contradiction may be hinted at. 

appeal in terms of external borrowing, Brazil, Mexico and Indonesia are the world's three most high-debt countries. Is also the world's three leading deforesters. For very poor and hungry, life-saving comes from the rainforests. Conversion allows the survival of some hardwood ashes. The wood export in the transformation of the survival of the others. Meanwhile, the entropy of all our planet's long experience, increase the value of the rainforests. 

Increasing the number of scientists are now claiming conflict of interest between the system and the physical, economic development, not just the result of a consequence of these phenomena. due to Miller and the Environment: CONVERGING Crisis (1991) external debt interest payments directly to depletion of natural resources links.Excluding the majority of the academic nature of the argument, now depend on for two examples. 

Begin to develop ideas by Michael Lipton of the University of Sussex (1992) at.Imagine a farmer who wants to buy a plot of land and farm. costs and funding should only be bought on borrowed funds. Earth's high-technology intensive, and the expected annual net cash flow is 150 pounds sterling per year to produce 15 complete destruction of the productive capacity of land and bring support. This will, perhaps, the farmers who work in the case of land prone to desertification. The only alternative to 100 pounds per year of net cash flows produced by technology, and allows the land to recover its production capacity to keep forever. 

Discounted cash flow analysis, and thanks to the farmers to compare the two management approaches and targeting more profitable. interest rate for each of the present value ("PV") is calculated for each set of cash flows. Agriculture is the largest amount of present value approach provides for the implementation. 

High-yield method 

5% PV cash flows = 1556.95 
PV cash flows = 10% 1140.91 
Low yield method 

PV at 5% = 2000 
1000 PV = 10% 



calculation shows clearly of great interest for the current price of 5% (2000) at the rate that low-intensity agriculture is the focus, now 10% higher value (1140.91), while the rate for a high intensity version. In short, intensive agriculture and thus a higher interest rate also increased desertification stimulus. 

This sad result is quite normal, except during the process of gradually reducing the current output value of land associated with zero. £ 100 net annual income of about £ 0.85 p'yatdesyat the current value of the interest rate is 10% per year. It is not surprising, analysts, discounted cash flow analysis which is based on the special attention that the earth produces in fifty years. time in the desert have little or no contact with Earth, its almost not seen as a contribution to the current value. Lipton is confirmed: 
1977-79 a significant increase interest rates, steady since then, incentives to increase - families, businesses and governments - to use natural resources now, and do not see the consequences later ... Rio takes part in the hunger, fatigue and hunger sliding warned. Ghosts of our interest rates quickly. 

Despite the recommendations of the previous analysis of the open land for bankruptcy may make sense to think short-term returns to the collection. Immortal chicken with golden eggs in this Treaty are not traded in each of his immortality in favor of a two weeks at the same time to the golden eggs. , It seems, however some of the natural assets of money will be discounted flow analysis can be sacrificed. the victims of desertification, species extinction or contamination of nuclear power stations take a long look, whether or not the principle remains the same. long-term effects of compound interest in action on the current value of almost anything.Generations of his back problems and was not the voice of the creation of the house. 

Excluding securities and Colin (1994) except at the price of type "uniform, negative exponential" over the practice is almost always wrong, argues, a method for assessing the physical world, which provides a wealth of function to non-exponential.Your comments: 
We are less ready to go to our interests than we would refuse to give a lower value because it is very uncomfortable and even a threat to our current shameful indifference to the output because of a distant future. 

However, in the near future, where the terms, except to promote the discussion of consumption patterns still see him today. Let, except for two of us choosing to use the river bank holidays. The first stream is not involved in the next ten years to take vacations, and then a year of vacation a year. The second stream of a holiday than a decade, the initial period of one year and one week later are included. Now the real monetary value of the number of units Festival, and those years when the holidays do not appear as an element to be zero. Analysis of the time period extends to T50 as expected life of the individual and the other 20% of the discounted annual rate. 

Fairs later 

PV = 0.807, 20% 
The first of the Saints 

PV 20% = 4,1924 


Select the stream is discounted holiday and the first (present value of 4.1924), the flow of benefits, that 'after the holidays (the present value of 0.8075) compared with the choice. All of these will result to the observation that the sacrifice current satisfaction awards later, and it seems discounted utility is suspect as well as means to assess the projects. tools such as money, why buy the same except for the subject is a surprising start. 

Ah, critics say, elderly people can take a holiday, or prefer to be in as soon as possible - in fact, this does not justify the discounting of future consumption?Consumption is consumption, not tomorrow better than today? Such arguments are not properly dealt with here, but it is not easy to argue that at some points, sometimes of consumption, the consumption of a better tomorrow today. Although the old man would be the life of one day instead of a breakfast, and breakfast and the residual life of today. 

The existence of market interest rates do not always play in the analysis of the reasons for this exception. William Cline of the economy Meltdown (1992) as a highlight, they are not alternatives. However, the effects remain: 
... The main reason for discounting future consumption will be higher income people may be in the future than at present, and the marginal utility of consumption below ...pessimism is related to future income per capita consumption is not at all intuitive. 

any discount on the basis of different generations, EJ Cline quotes mixed with cost-benefit analysis: Informal Introduction (1975): 
... A person does not have any business evaluating future costs 100 less 50 years by 10 percent when it is not in any case, there is a go ... In these cases, a zero rate applied to benefits for temporary, arbitrary, but people today are probably a temporary rate of benefit or interest rate on consumer loans only to be better than the market. 

physical assets are not depreciated, if all reinvestment performance at frequencies of compounding processes and the extent diktatu, was not marginal profitability of investment and limited opportunities to go down after a long work, the convention could be the scenario of a fixed interest rate increase will be applied to the process of truly real-world Reverse the process recipe provides more absurd results and analysis of the discount, we will extend the review period.

Removed the equation in two different interest rates, simply because there is no difference between the interest rate is one of them is called.
