During a sudden and severe drought, the market price for bottled water in an isolated town doubles. A local official proposes a law to force the price back down to its pre-drought level, arguing that the current high price is unfair. Critically evaluate the official's proposal and the argument that the high price is simply 'unfair'. In your evaluation, use the concept of what a market price indicates about the value society places on a good, assuming the market for bottled water is competitive.
