The Digression on the Value of Silver in Chapter 11 of Book 1 is one of the longest and most difficult chaptersin Adam Smith's The Wealth of Nations.
I delayed publishing Book 1 of my simplified version of The Wealth of Nationsand published Books 2 & 3 instead because paraphrasing the Digression in Book 1 would require some time and effort.
The first step is to organize the Digression which starts at Paragraph 96 and ends at Paragraph 239. For reference, I used both the 'capitalist' econlib version and the 'socialist' marxist.org version
Smith wanted to prove that gold and silver prices are not correlatedwith the wealth or poverty of society. Instead, he wanted to prove that it is the money price of some rude produce relative to the main food grain (such as wheat), which is the clearest indicator of a society's wealth or poverty.
To do this, he had to:
In the same way, we want to objectively prove that GDP (measured in dollars) is not a proof of the wealth of a country, so we follow Smith's methodology in getting the 'grain values' of key rude produce to easily say whether the US or China or the EU is really wealthier and which country's wealth is based more on real value, instead of fake or nominal value. Who wouldn't want to live in a country that has more real value and is more resistant to economic crises?
SORAnomics uses two measures combined to replace GDP as a measure of a country's wealth:
Purchasing power is the net revenue from GDP or gross revenue of a society. It is made up of the net profits that go to the wallets of business owners, and wages that goes to the wallets of employees. The expenses for interest payments, fees, etc. are deducted from the computation of net revenue. For example, the GDP or gross revenue of Singapore is nominally $323.9 b. Its purchasing power would be the GDP minus tax payments to government and the cost of money used up in producing that GDP.
This cost of money is the expense in financing the money to be used to circulate value in any economy. In order to buy bread, I have to work for money and then use the money to buy bread. If my work could be bartered directly for bread, then money would not be neededand all the bankers, financiers, ATMs, bank branches, etc could be freed up and made to do other things useful for society.
There are three ways to arrive at Purchasing Power
Individual PP= Quantity and Quality of Goods and Services that can be bought by a person, pegged in either gold or grain
National PP= Summation of Individual PP
National PP per capita= National PP divided by population
The Grain index, as stated in the Digression is the ratio of the price of commodities to the price of grain. For example:
|1 kg Rice can buy:||330 grams chicken||100 grams chicken|
|1 kg Chicken can buy:||3.33 kg Rice||10 kg Rice|
So it means that chicken is really cheaper in the Philippines, meaning that while Vietnamese enjoy cheaper rice, Filipinos enjoy luxuries better (to Smith, meat is a luxury). This is consistent if we replace chickens with cars. A Toyota Vios is 16,000 kg rice in the Philippines, but 44,250 kg rice in Vietnam. This would then guide people on which cities or countries they might want to move to, in order to match their social status, fulfilling the requirement of Adam Smith that our model must have a practical use. The rich could use this to justify moving to Singapore, while the lower classes might use it to decide to live in the Philippines or Vietnam.
|GDP per capita||$100,345 (1st place, 13x Vietnam)||$8,936 (2nd place, 1.19x Vietnam)||$7,510 (3rd place)|
|Rice Prices per kg||75 US cents or 1.1 SGD (2nd place or 1.5x Vietnam)||80 US cents or 40 PHP (3rd or 1.6x Vietnam)||50 US cents or 12k VND (1st place or cheapest)|
|Chicken Prices in rice||4.22 kg rice (2nd place or 1.3x Philippines)||3.25 kg rice (1st place)||8.33 kg rice (3rd place or 2.56x Philippines)|
|Toyota Vios in rice||73,636 kg rice (3rd place or 4.46x Philippines)||16,500 kg rice (1st place)||44,250 kg rice (2nd place or 2.68x Philippines)|
|Toyota Alphard Luxury Van in rice||206,000 kg rice (2nd place or 2.25x Philippines)||91,250 kg rice (1st place)||336,000 kg rice (3rd place or 3.7x Philippines)|
This model can of course be used for policymaking. Both Economics and SORAnomics will conclude that Singapore is the most prosperous country and Vietnam the least prosperous of the three, from the supply side. But from the demand side, SORAnomics can reveal much more info:
So by combining supply side GDP or Purchasing Power and demand side Grain index, we can get a more granular picture of the real economic situation of a society. By plotting the ratios of prices of different products and services relative to the Grain index annually, we can even determine the economic direction of a society and can better iron out kinks in a society's supply and demand. We can even use the data to plot exactly when the grain ratios started to change to then pinpoint specific laws that caused the problem or improvement. We can trace objectively when the oligarchy started in the Philippines and when Vietnam became anti-rich, by getting their historical annual SORAnomic Purchasing Power even without any knowledge of historical events -- this is what our machine learning is supposed to do.
In contrast, modern Economics measures the supply-side as gross supply or GDP (Gross product), and measures demand-side as CPI or nominal consumer prices measured in currency. This makes it difficult to value goods and services during bubbles and hyperinflation, causing a disruption in the supply chain like what happened in Zimbabwe. If a financial crisis hits a SORA system, the valuation can merely switch to the Grain index to keep the supply chain humming.
Under Economics, a country can theoretically have a single giant corporation exporting everything, having huge GDP while its workers starve to produce those exports at low cost. A GDP standard would still rate the starving country as wealthy. Our dual system, on the other hand, would properly expose the real poverty hidden by the nominal wealth just as it exposed the hidden middle-class poverty in Vietnam and the real poverty in the Philippines. In addition, our dual index eliminates the need for complicated subjective factors that are present in other indices like the Human Development Index, Happy Planet Index, Better Life Index, etc. The subjetiveness is only in what items are pegged aganst the Grain index.
|Measure of Supply||GDP as Gross Domestic Product or the gross sales in a country||Purchasing Power as the net revenue in a country after taxes, or whatever goes to the wallets of employees and business owners.|
|Measure of Demand||Consumer Price Index or prices of year X relative to year Y||Grain Index or prices of different goods and services relative to grain. For basics, it is fuel, electricity, water, rent, basic medical services and common non-essentials (meat, milk). For luxuries, cars, condominiums, etc.|
|Subjective Measures||Arbitrary, depending on think tank (Human Development index, Happiness index, etc)||Not-so-arbitrary. Measures are integrated in the items included in the Grain index. For example, a rich country might include prime beef and pork in the index, but a vegetarian country might not. In general, meat is included since Smith included it in his digression.|
|Ease or Difficulty||Difficult, needs to get accounting of all output, and various data on well-being which are difficult to get||Easy, Survey the purchases done by a sample population, and get the prices of benchmark commmodities.|
