The oldest and most popular instrument of etatistic monetary policy is the official fixing of maximum prices. High prices, thinks the etatist, are not a consequence of an increase in the quantity of money, but a consequence of reprehensible activity on the part of 'bulls' and 'profiteers'; it will suffice to suppress their machinations in order to ensure the cessation of the rise of prices. Thus it is made a punishable offence to demand, or even to pay, 'excessive' prices.
