This paper examines the ability of a policy maker to fashion equilibrium outcomes in an environment where market participants play a coordination game with heterogeneous information. We consider a simple model of regime change that embeds many applications examined in the literature. In...

A common feature of many speculative attack models on currencies is the existence of multiple equilibrium solutions. When choosing the equilibrium strategy a trader faces Knightian uncertainty about the rational choice of the other traders. We show that the concept of Choquet expected utility...

This paper examines the opportunity of exchange rate regime flexibilization in Morocco under the policy of capital account liberalization. Basing on our findings in Ezzahid and Maouhoub (2014), we develop a new theoretical game model with four economic agents, namely: monetary authorities,...

While virtually all modern currency crisis models recognise that the decision to abandon an exchange rate peg depends on how tenaciously policy makers are willing to defend it, they seldom model how this is done. We incorporate both the mechanics of speculation and of a defence policy against...

With the internet boom of early 2000 making access to trading the Foreign Exchange (FX) market far simpler for members of the general public, the growth of ‘retail' FX trading continues, with daily transaction volumes as high as $200 billion. Potential new entrants to the retail FX trading...

This paper develops an analytical framework to explain how a liquidity shock or a shock to the aggregate haircut on collateralized assets amplifies financial crisis in a carry trade recipient country. The model allows roles for shocks to the size of a haircut, strategic behaviour across currency...

A successful speculative attack against one currency is a wake-up call for speculators elsewhere. Currency speculators have an incentive to acquire costly information about exposures across countries to infer whether their monetary authority's ability to defend its currency is weakened....

We propose a speculative attack model in which agents receive multiple public signals. It is characterised by its focus on an informational structure which sets free from the strict separation between public information and private information. Diverse pieces of public information can be taken...

Financial markets and macroeconomic environments are often characterized by positive externalities. In these environments, transparency may reduce expected welfare from an ex-ante point of view: public announcements serve as a focal point for higher-order beliefs and affect agents' behaviour...
