We characterize the Ramsey optimal rate of inflation in a model with a foreign demand for domestic currency. In the absence of such demand, the model implies that the Friedman rule—deflation at the real rate of interest— is optimal. We show analytically that in the presence of a foreign demand for domestic currency, this result breaks down. Calibrated versions of the model deliver optimal annua...

This paper investigates the impact of speculative trading on foreign currency markets. A review of economic literature reveals that there is still no agreement to whether speculators amplify or tame fluctuations of exchange rates. Relevant system dynamics literature suggests that trading by speculators contributes to the formation of price bubbles. However, very few system dynamics papers exist...

International cross-border private hospital chains need to apply the standards for foreign currency translation in order to consolidate the balance sheet and income statements. This not only exposes such chains to exchange rate fluctuations in different ways, but also creates added requirements for enterprise-level IT systems especially when they produce parameters which are used to measure the...

Financial crises are linked to large output declines, but the potential links between different types of crises remains unclear. To enhance understanding we study the interdependencies between domestic banking crises, on one hand, and external financial crises, including currency and sudden stop crises, on the other in a quarterly global panel. We further ask how the different crises relate to ...

Given the increasing importance of financing in foreign currency denominated debt, researchers have shown the conditions under which raising capital denominated in a foreign currency becomes feasible. We extend this literature in the context of a multinational corporation (MNC) by modeling the rivalry between equity and debt under a modified general equilibrium framework. We derive (i) internat...

We study the integrated operational and financial hedging decisions faced by a global firm who sells to both home and foreign markets. Production occurs either at a single facility located in one of the markets or at two facilities, one in each market. The company has to invest in capacity before the selling season starts when the demand in both markets and the currency exchange rate are uncert...

This paper develops a model of the black market for foreign exchange in which black market currency is demanded and supplied by tirms engaged in smuggling. It is demonstrated that quotas or foreign exchange rationing are not necessary to induce the coexistence of legal and black foreign exchange markets. Variants of the model analyze the implications of capital flight, unbalanced trade, quotas,...

Market participants’ risk attitudes, wealth and portfolio composition influence their positions in a pegged foreign currency and, therefore, may have important effects on the sustainability of currency pegs. We analyze such effects in a global game model of currency crises with continuous action choices, generating a rich set of theoretical comparative static predictions related to often discus...

the frequent occurrence of currency crises in recent years brought the early warning literature back in the researchers spotlight. in recent years, concept of an early warning system (ews) developed that should be able to identify various costly events, such as currency crises, early enough for policy makers to reduce the costs. this study attempted by using iran's economy quarterly data d...

Firms sometimes write price lists or catalogs for their exports, so they set prices for a period of time and do not adjust prices during that interval in response to changes in their environment. The firm sets the price either in its own currency or the importer’s currency. This paper draws a simple link between the choice of currency and the pricing decision of a firm that changes prices in re...
