We establish a dynamic currency attack model in the presence of a large player (LP) based on Abreu and Brunnermeier (2003), which differs from most existing one-period static currency attack models. In an attack on a fixed exchange rate regime with a gradually overvaluing currency, both the...

Abreu and Brunnermeier (2003) study stock market bubbles and crashes in a dynamic model with a continuum of rational small traders. We introduce a large trader into their model and apply it to currency attacks. In an attack against a fixed exchange rate regime with a gradually overvaluing...

An event study is used to assess the views of Keynes and Friedman on speculation. Speculative extremes are ranked by intensity of sentiment and weight of speculative activity. A unique dataset of risk-reversal skew on option prices is used to measure the intensity of speculative sentiment; the...

Economists invoke Mundell (1961) in arguing for the general policy of a flexible exchange rate regime as a means of restoring equilibria after shocks. But there is a discrepancy between the intent of the general policy and attempts at its implementation as identified by specific changes in...

The paper traces the dangers in the closed economy perspective of a monetary policy focused on a domestic inflation goal under a clean float. Field evidence of the damage wrought from this perspective is reinforced by that from a laboratory experiment. The laboratory experiment avoids...

This paper’s field evidence is: (1) many official sectors rapidly forget the damage of the 1982-85 exchange rate liquidity crisis and reverted to what caused that crisis, namely a closed economy clean floats perspective; and (2) the 2006-2008/9 exchange rate liquidity shock would have been more...

On 19 June 2010 the Chinese authorities announced that the renminbi (RMB) was henceforth to be pegged to a currency basket. Yet, it has quite closely followed the USD, though having appreciated by 2.7 % by the time of writing. At the G20 Seoul Summit on 11-12 November 2010, China committed to...
