I'm explicitly not including auto rates in this. I actually think the
PBA did pretty well, but my highest priority is preventing scams-- a
bank should be a trustworthy place to invest your assets. Most normal
transactions are low-volume but scams are very high-volume, and
diminishing returns should significantly slow down the latter without
much affecting the former. I'm not sure I've set the limit at the
right place, but the rate multipliers can be changed once the IBA has
some real-world experience. Auto rate systems don't necessarily
enable scams, but your assumption with the PBA was wrong: there was
too much apathy for your expected periodic mini-scams to stabilize the
rates, and I think that applies in general for assumptions about
market forces and whatnot. So I'm going to go with a manual system
this time, and we'll see what happens!
Second draft, with lots of bugfixes, slightly changed multipliers
(thanks for the advice, BobTHJ), and initial rates at the bottom:
===============================================================================
I. IBA
This is the Industrial Bank & Agora. The currency of the IBA is
zorkmids (zm); the recordkeepor of zorkmids is the President.
Any person CAN join this contract by announcement. Any party to this
contract CAN leave it by announcement, unless e is involved in a
pending Offer.
The President of the IBA is comex.
II. Summary
- You can join the contract by announcement. Please join before
attempting to make Offers or vote ISELL-- your only obligations are
to uphold the terms of Offers you make.
- You can deposit 4 assets per week for the standard rate; further
deposits give you diminishing returns to prevent scams, but you can
still get a good price for up to 10.
- You can always withdraw assets for the standard rate.
- You can intend to sell or buy assets, naming a price; this is known
as an Offer, and other parties can fill the Offer by announcement.
- ISELL works like SELL, but you can vote ISELL on dependent
actions as well as decisions.
III. Banking
Every asset has a Rate in zorkmids, intially zero. The President's report
includes a Rate List containing all nonzero Rates.
IV. Withdrawal
A person CAN withdraw an asset in the IBA's possession if e has at
least its Rate in zorkmids; those zorkmids are destroyed in eir
possession and the IBA transfers the asset to em.
V. Deposits
A person CAN deposit an asset by transferring it to the IBA; e then
gains the Effective Rate in zorkmids.
The Effective Rate for a deposit is its Rate, multiplied by a value
depending on the number of previous deposits made in the same week
with the same Executor, and rounded to the nearest integer:
prev rate
0-3 1.00
4-6 0.90
7-9 0.80
10 0.73
11 0.62
12 0.50
13 0.38
14 0.26
15 0.18
16 0.12
17 0.08
18 0.05
19 0.03
20 0.02
21- 0.01
VI. Offers
An Offer is an entity with three fields:
Selling: (a nonempty list of assets and/or actions)
For cost: (a nonempty list of assets and/or actions)
Repeats: (a nonnegative integer, or infinity; default 1)
A person CAN create an Offer by announcement, thus becoming its
offerer. A person CAN destroy an Offer for which e is the offerer by
announcement.
A party (the filler) CAN fill an Offer by announcement if and only if:
- the offerer is a party, and
- the offerer has the assets in the 'Selling' field (if any), and CAN
perform the actions in that field (if any), and
- the filler has the assets in the 'For cost' field (if any), and CAN
perform the actions in that field (if any).
When an Offer is filled,
- the IBA acts on behalf of the offerer to transfer the assets in the
'Selling' field to the filler, and to take the actions in the
'Selling' field, and
- the IBA acts on behalf of the filler to transfer the assets in the
'For cost' field to the offerer, and to take the actions in the 'For
cost' field, and
- the Offer's 'Repeats' field is decreased by one.
An Offer with zero Repeats is automatically destroyed.
To intend to sell X for Y is to create an Offer with X as 'Selling'
and Y as 'For cost'; to intend to buy X for Y is to create an Offer
with X as 'For cost' and Y as 'Selling'; to intend to sell A*X for Y
each is to create an Offer with X as 'Selling', Y as 'For cost', and A
as 'Repeats'; etc.
Examples:
- I intend to sell a WRV for 8 zm.
- I intend to sell 4 G# Credits for 2 zm each.
- I intend buy a Land for 3 zm.
- I intend to sell a WRV for a Land.
VII. Selling Votes
Voting ISELL(X) on a decision is equivalent to intending to sell a
number of votes equal to your voting limit on that decision for X.
Voting ISELL(X - A*Y) on a decision (A equals one if not specified) is
equivalent to intending to sell A votes on that decision for X, and
then voting A*Y.
Examples:
- ISELL(8 zm) - allow all of your votes to be
purchased as a block for 8 zm
- ISELL(8 zm - AGAINST*8) - cast 8 AGAINST votes, which can be purchased
as a block for 8 zm
- 8*ISELL(1 zm) - allow each of your votes to be purchased
separately for 1 zm each
- 8*ISELL(1 zm - AGAINST) - cast 8 AGAINST votes, each of which can
be purchased separately for 1 zm
When an Offer is filled that specifies a number of votes on a certain
Agoran decision in the 'Selling' or 'For cost' field, the offerer or
filler respectively
- retracts enough (if any) of eir ballots on that decision that the
following ballots are valid and do not exceed eir voting limit;
- casts the specified number of ballots with the option specified by
the other party; and
- SHALL NOT retract these ballots.
If this process is impossible, the Offer CANNOT be filled.
Retractions of ballots caused by this process are performed in the
order the ballots were originally submitted.
VIII. Selling Support/Objection
Opining ISELL(X) on an intent to perform a dependent action is
equivalent to intending to sell an opinion on that action for X.
Opining ISELL(X - Y) on an intent to perform a dependent action is
equivalent to intending to sell an opinion on that action for X, and
then opining Y.
Examples:
- ISELL(4 zm)
- ISELL(4 zm - support)
- ISELL(4 zm - object)
When an Offer is filled that specifies an opinion on a certain
dependent action in the 'Selling' or 'For cost' field, the offerer or
filler respectively
- withdraws all previous support or objection for that action,
- supports or objects to that action, as specified by the other party, and
- SHALL NOT withdraw that support or objection, or thereafter support
or object to that action.
This process also applies to contract-defined psuedo-dependent
actions whose behavior differs from that of a dependent action only in
the values of time limits, or not at all.
IX. Selling Agreement
When an Offer is filled that specifies agreement to certain terms in
the 'Selling' or 'For cost' field, the offerer or filler respectively
SHALL follow those terms.
X. Motions
A motion is an entity which acts identically to an Agoran decision,
except that the requirement that the voting period last at least seven
days is waived, and, by default, the eligible voters are the parties
to this contract, each eligible voter's voting limit is one, and the
voting period lasts 72 hours.
Any party CAN initiate a Motion to Amend, specifying a set of
amendments to this contract. For this motion, the adoption index is 2.
If the option selected on a Motion to Amend is ADOPTED, this contract
is amended as specified.
XI. Changing the Rates
A Rate List is a list of assets and associated Rates. To effect a
Rate List is to set the Rate of each asset in the list to the
specified value.
The President CAN effect a Rate List without two objections in 48
hours. Any party CAN initiate a Motion to Effect, specifying a Rate
List. For this motion, the adoption index is 1. If the option
selected on a Motion to Effect is ADOPTED, the specified Rate List is
effected.
XII. Rates are Self-Ratifying
One week after the publication of a Rate List purporting to be part of
the President's report, the Rate List is effected unless, less than a
week after its publication, any person publicly
- challenged the Rate List's veracity, or
- purported to effect a different Rate List.
XIII. The IBA is a Partnership
Parties to this contract SHALL collectively ensure it fulfills its
legal obligations. If the Sentiment of this contract is ever not
Legalistic, any person CAN flip it to Legalistic by announcement. If
the Disclosure of this contract is ever not Public, any person CAN
flip it to Public by announcement including its text and list of
parties.
XIV. Pending Offers
A person is involved in an Offer if e is its offerer or filler. A
pending Offer is an Offer whose effects impose an ongoing or
unsatisfied obligation on a person involved in it.
XV. Presidential Restriction
The President, when performing actions allowed to em by virtue of the
office, SHALL act in good faith, considering the best interests of
this contract and the game.
XVI. Initial Rates

then this section repeals itself:

2 Crop 45
3 Crop 21
