Well, if I have not completely lost all my readers, even
Magpie, who seems to have a taste for this sort of arcana, let me
continue. Re-reading what I wrote
yesterday, I realize that by referring to some random commodity as
"a," I invite confusion. Indeed,
when I re-read the last sentence from yesterday's episode, it looked at first
as though I had ended in the middle of a sentence. So henceforth I shall use "A"
rather than "a." I hope that
makes things a trifle clearer. Anyway,
here we go.
X's possessions
are simply the totality of all the ownable goods towards which, at the
specified time, X bears the relation of owner. If we assume -- as classical political
economy does -- that the goods of which we speak are commodities, which is to say goods partitioned into categories,
treated as interchangeable within categories, and quantifiable therefore within
categories along natural physical dimensions [so many bushels of wheat, so many
tons of iron, so many power looms, etc.], then we may define an economic
agent's holding as a vector, the ith
element of which is the naturally measured quantity of the ith type
of good [according to some conventional ordering] toward which the agent bears
the relationship of owner as defined
by the ruling legal system. I add the
phrase "along natural physical dimensions" to make it clear that at
this point I am talking about things, not quanta of value. [A vector is a list, but "list"
does not sound impressive at all, and "vector" makes it manifest that
I am a very serious person. Much of
modern economic theory consists of such like maneuvers.]
Economic agents, of course, own specific determinate
physical goods [this bushel of wheat,
that pair of shoes], but this fact is
abstracted from in the concept of a holding.
I am now going to try to put all of this into symbols. Be patient.
This is easy if I am writing by hand, but rather daunting if I am using
WORD. I have never done this before in
WORD, and it may take me several days to type in WORD what it took me a few minutes
to write by hand. So much for technological
progress. [RATS. I solved the problem of inserting a summation symbol into WORD, and then, when I tried to copy it into this benighted blog framework, it simply disappeared! I give up. In future I shall write in long hand and then send mimeographed copies of what I have written by perswonal courier to anyone who wants them! Phooey.]
Let hi
= (hi1, hi2,
... hin) = the holding of economic agent i, where hiq = the
quantity of commodity q owned by individual agent i, with i = 1, 2, ...., s.
If H = the sum, from 1 to s, of the h sub i
[This is where I tried to put in a summation symbol] and β = (β1, ...., βn) = the
vector of gross outputs.
Notice
that the equality implies that every bit of output is owned, and that nothing
is owned save the output of this cycle.
There are no fixed capitals in our model yet, and not even any durable
personal possessions.
When a market exchange takes place, economic agents make a
legally enforceable agreement, the effect of which is to accomplish a mutual
transfer of ownership of some non-zero portion of each party's
possessions. This mutual transfer alters
the holding of each agent in such a way, obviously, as to leave the sum of
their holdings unchanged. During the
interval of exchange between cycles of production, therefore, H = β is constant, regardless
of the number of transactions their frequency, or the prices [ i.e., exchange
ratios] that govern the magnitudes of their exchanges.
Since a market exchange is a mutual transfer of ownership,
the effect of which is to alter the composition of individual possession
vectors, and thereby to alter holdings,
it is a matter of no importance whether any physical change takes place in the
location and arrangement of the ownable goods being exchanged. We can imagine that the agents carry their
goods about on their backs. like the Balnibarians encountered by Gulliver on
his third voyage; or we can suppose them
to conduct their affairs entirely on chits of paper, the goods having been left
elsewhere. Also, it is clear that
whatever has had the status of ownable good ascribed to it by the appropriate
legal procedures can become an element in a commodity exchange: a bushel of wheat, a bolt of cloth, the
performance of a Bach cantata, a trademark, a scientific idea, or a municipal
office.
Now [I am creeping up on the idea of money, be patient], Let
us suppose that a private party who has hitherto engaged only in transfers and
exchanges of such commodities as gold and silver, now offers as a service [for
a nominal fee] to store and care for its customers' gold. [Other parties might offer the same service
for wheat or iron, but never mind that.]
The owner of a quantum of gold who decides to avail herself of this
service can transfer legal possession of the gold to the bank [as this service
provider now becomes]. In return, she
receives a certificate of entitlement [regardless, by the way, of whether the
gold is physically moved from the owner's strong box under her bed to the
imposing building maintained by the bank].
The certificate announces that its owner, the depositor, has the legal
right, whenever she [or he, or they, or it] may choose, to present the certificate
to the banking house and receive in return the amount of gold indicated
thereon.
What effect has this new banking service on the structure of
possessions and holdings? If the
depositors are entitled, by their certificates and by the laws governing them,
to recover identically the same particles of gold that they placed on deposit,
then the answer is clearly none at all.
The gold is,, as it were, in safe deposit, just as one agent's wheat may
be in a warehouse, or another's beef in a rental meat locker.
But since we are assuming a homogenization of commodities
sufficient to permit their classification, categorization, and aggregation within
categories, we may suppose that it is a matter of indifference to the
depositors whether they receive back physically the same gold which they have
deposited, as opposed to gold of the same quality [category] and quantity. This assumption rules out, as instances of
our analysis, such goods as a specific painting by Rembrandt, or a performance
of the Beethoven violin concerto by Hillary Hahn. It is scarcely plausible that an art
collector who had deposited Rembrandt's painting of Aristotle Contemplating a Bust of Homer would accept, on
presentation of the deposit certificate, an equal number of paintings, or an
equal number of Dutch Old Masters, or an equal gold-value of paintings, or even
another Rembrandt. The depositor would
demand back the specific painting she had deposited. Nor would a music connoisseur be satisfied
with an alternative performance of an alternative concerto for an alternative
instrument by another composer!
Regarding your troubles with characters. You can use the same syntax used by computer algebra systems:
ReplyDeletesum(F(x), x, x_lo, x_hi) = F(x_lo) + F(x_lo+1) + ... + F(x_hi)
Say, your sum above ("If H = the sum, from 1 to s, of the h sub i"), would become
H = sum(h(i), i, 1, s)
(I used the functional notation for want of a subindex notation; you can define the convention that h[i] or h_i or anything you might prefer denotes "h sub i").
You could define similarly other operators.
Or, alternatively, if you prefer (and perhaps it's best), I can write the instructions, step by step, and post them in my own blog, so that you can upload graphic files (charts, figures, tables, equations) in your blog.
You write them in your application (say, Word), copy them to Paint and save them in a folder you keep only for such use (say MyGraphs) as JPG. Then, you open Blogger and upload them from your computer and into your post.
A very similar process also allows you to upload media (movies, music, etc.).
