I agree, this is a difficult problem and I think the BBs took necessary actions last off-season to deal with the inflation problem. However, inflation and deflation will be a constant and long-term issue, so you might as well put a system in place to deal with it.
1) What should be the role of the BB team in the economy? Is it our job to prevent inflation and deflation? Is it our job to allow both, but keep them within certain bounds? Is it our job simply to keep competitive balance, but to ignore market fluctuations as long as that balance is not threatened?
Well, in short yet. The problem is that if you have long-term inflation or deflation of player values (to any large extent), it makes fixed-price elements in the game either too expensive or too cheap. For example, if you can sell a player for $1M in one season and add to your arena with the proceeds and a few seasons later, you can sell the same type player for $2.5M then add to your arena, its like the cost of the arenas went down by 60%.
The same thing happens with massive deflation. For example, when HT had its deflation cycle a few seasons back, excellent coaches just disappeared.
Same thing would happen with BB, if you have massive inflation, everybody would buy the most expensive coaches, max scouting and monster arenas etc. Long-term deflation, the reverse. And then those decision elements of the game disappear or become trivial.
2) Under what circumstances should we act without much prior notice? For that matter, how much notice is appropriate typically for different changes?
Honestly, I would be doing it constantly. I would monitor the cash and wealth of the teams in various divisions and increase revenues accordingly. Merchandise Revenues already seems to have some randomness to them...what if they went down by $1k for everybody in div 2 for a week if div 2 teams seems to have a huge surplus or excessive cash flow etc. And the reverse. Over time, I think small adjustments every week are much more equitable then dramatic changes every off-season or twice a season. And if overall, the same about of money was distributed between all the teams, then you wouldn't have much change in the overall player market.
I'm sure people would argue that this adds a level of uncertainty, but its far less than finding out that your division is going to have a 25% tax next season or 50% annual deflation or whatever, don't you think?
3) How important is it to keep a constant set of rules? There is always a tradeoff between an ability to solve problems and an ability to keep the ruleset constant and let teams make long-term plans.
Part of being a good manager is dealing with a little uncertainty and overcoming it. Isn't that the point of having injures in a game like this?
I think everybody should expect the rules to change over time...I think we all want to see the game evolve. Its more a matter that large changes create a lot of upheaval and unhappiness.
