In the economy of Robberia, the monetary base is $2,000. People hold half of their money in the form of currency (and thus half as bank deposits). Banks hold a quarter of their deposits in reserve.

If, in the face of this panic, the central bank wants to conduct an open-market operation to keep the money supply at its original level, does it buy or sell government bonds? Calculate, in dollars, how much central bank needs to transact.
