>>2562210Introducing Fixed PricesWhat if instead of a bidding for resources with variable-price bids, the bids must be done at fixed prices? I very strongly feel that a resource-allocation system needs to have some flexibility. Imagine only one pseudo-firm wants some resource, but doesn't have the play-money. Isn't that a very silly situation? If the prices are fixed, it should be possible and indeed trivial for that pseudo-firm's spending to exceed its budget to get the resource.
What is the purpose of the budgets? To give the pseudo-firms power to access resources. If society decides to give pseudo-firm A twice the budget society gives to pseudo-firm B for the next period, our working assumption is that society evaluates what A will do as more important than what B will do (even though the two decisions might be made by two different committees without a single person being a member of both). If we have to state any sort of ratio of importance here, we assume that what pseudo-firm A will do is deemed as
twice as important by society compared to B. (I'm assuming here A and B are in the same tier. Like in the system with flexible prices, we can have lexicographic tiers of importance for the pseudo-firms, so that a lower tier only gets the leftovers from the higher tiers.)
Suppose the spending period isn't over yet so no new budgets are yet available, but both pseudo-firms are already out of play-money for accessing resources. They are
going into minus. I'm using this phrasing for a reason. I'm NOT saying they are "going into debt", because
they won't have to pay back anything. Any pseudo-firm's play-money account, whether positive or negative, gets reset to zero at regular intervals and it gets a new budget.
Suppose there is a resource that nobody is bidding for except A and B, each asking for all of it. (Despite using fixed prices here, I'm still using the term "bids", because like with variable-price bidding the requests are not instantly approved, instead we wait for a while till bids are closed; and if the demand exceeds what's in stock, we allocate the stuff in a way that follows a simple rule that has nothing to do with the order in which the bids arrived.) Suppose both A and B are in minus. Again, it is clear that the resource should be assigned despite the lack of play-money in the accounts. It's time to get even more into minus. But how should the assignment be done exactly?
We want the initial budgets of different sizes to have meaning. So, we cannot ignore how far the pseudo-firms go into minus. A pseudo-firm going into minus should have its
RAP (
Resource-
Access
Power) reduced. But what is the soundest rule here? We could either do this:
1. For each requesting pseudo-firm look how far into minus they go if they get one more unit of the resource and get lowered their already negative play-money account by the unit's price, then give to the pseudo-firm with the then resulting smallest minus, rinse and repeat for the next unit of the resource.
Or this:
2. Look at negative play-money accounts potentially getting more negative like above, but measure the size in proportion to the initially assigned budget.
Suppose A and B arrive at a negative balance of the same size at the same time. If we only look at their negative balance in our formula for determining their respective RAP, we have to say their RAP is equal and give each of them half of what's available of the resource. But
society's decision was to give A more RAP than B and society hasn't made a new decision on that. So we do the second thing and look at the proportions. For each pseudo-firm, whether they are in minus or not, we ask: What fraction of your initial budget will you be at if you get one more unit of this resource? This number can run from close to one to zero to minus…
basically no limit here, and we give the unit to the pseudo-firm with the highest value (using pseudo-firm rank as tiebreaker), rinse and repeat for the next unit of the resource.
I haven't talked about different procedures for short-term operational stuff and the longer-term stuff with their distinct budgets. I haven't talked about transport costs. Worst of all, I haven't talked about how pseudo-firms need
combinations of things to use in production recipes, a fact which requires
INTERVENTION BY A STRONG CENTRAL AUTHORITY to reshuffle some resource assignments to make the more important ingredient combinations complete. Over time, the market-like structures will hopefully become less important and shrink and in-kind planning will increase. What is shown here is all very abstract and simplistic, but despite that, we have three important findings:
1. Assigning resources via variable-price bids goes together with hard budget constraints.2. Assigning resources with fixed-price bids does NOT go together with hard budget constraints.3. We can use both systems.I haven't explained the third point yet, but it's simple: Some resources get a fixed price, some are up to auction as described in the earlier post. We can even split up the same resource and make available some amount of it in each system. Any pseudo-firm gets an account with a nano budget for penny fractions that can be used in the variable-price bidding (see the POMF argument in the earlier post), but aside from that it gets a big account for accessing both systems. It's just that it cannot go into minus to make a higher variable-price bid. These variable-price bids are strictly constrained by the budget limit, while the fixed-price bids are not.
