At t = t1 the left-hand time derivative of the exchange rate exceeds the right-hand • time derivative by ξ/α2 > 0. The fall of st to zero at time t1 induces a fall in the home interest rate, that increases the demand for money to compensate for the jump in the money supply at time t1 . Money market equilibrium is maintained and there is no need for the exchange rate to jump.

At p¯ > p0 , the whole stock of gold will pass into the government’s hands, thus building 2 In more general settings allowing for positive marginal extraction costs, the rate of growth would be equal to the real rate of interest less the marginal costs. 40 The Macroeconomic Theory of Exchange Rate Crises up a buffer stock the authorities will use to maintain the ruling price. Private agents are unwilling to hold gold and sell their entire stock to the government at the price p¯ at t = 0. From t = 0 onward the demand for gold by consumers will be X p¯ = A¯p−α , and this is also the amount the government will supply each time to maintain market equilibrium and sustain the fixed price.

With a fixed real money demand at the pegged exchange rate, the money supply cannot increase in equilibrium.
