Markets reallocate scarcity, but rules decide outcomes
Australia’s water-market experiment shows scarcity can be handled via trading that reallocates water to higher-value uses, yet fairness, speculation, and performance hinge on regulation, information, and trust.
Speculators can improve markets, not always harm
Outside investors can make water markets more efficient when they buy low and sell high, adding trading liquidity; harm is more plausible when speculation turns into bubbles, divorced pricing, or destabilizing credit effects.
Inflation control depends on credibility and expectations
Inflation targeting worked without immediate recession because multiple equilibria exist: credible transparency can shift beliefs toward a virtuous low-inflation path, while weak credibility lets expectations lock into a high-inflation trap.
