This paper examines how unhedged currency exposure of firms varies with changes in currency flexibility. A sequence of four time periods with alternating high and low currency volatility in India provides a natural experiment in which changes in currency exposure of a panel of firms is measured, and the moral hazard versus incomplete markets hypotheses tested. We find that firms carried higher ...

This paper, considering revenue and cost exposure channels, investigates the effects of exchange rate behaviour on fixed capital investment in Mexican manufacturing sector over 1994-2002. We find that i) currency depreciation has a positive (negative) effect on fixed investment through the export (import) channel; ii) exchange rate volatility impacts mostly export oriented sectors; iii) the sen...

A cash-in-advance model in which the cost of buying goods with a foreign currency is decreasing in the economy’s accumulated experience in transacting in the foreign currency is shown to display hysteresis in money velocity; that is, a temporary increase in expected in ation can cause a permanent increase in velocity. In addition, the model implies that the domestic currency does not have to do...

Given current concerns on foreign currency exposures in emerging economies, we examine the currency denomination of bank loans. We compare the currency requested by borrowers and the currency decision subsequently made by a bank in Bulgaria prior to the current crisis. We analyze more than hundred thousand loans to sixty thousand different firms granted during the period 2003-2007. We relate th...

We describe the framework for building an electronic currency system. We detail the design of the components of the electronic currency system and the relationship among them. Contrary to the previous electronic currency literatures, which focus exclusively on electronic currency protocol designs, we address how to achieve both transaction atomicity and transaction anonymity at the presence of ...

In this paper, we prove the local well-posedness of free boundary problem for incompressible Euler equations in low regularity Sobolev spaces, which velocity is a Lipschtiz function and surface belongs to $C^{\f32+\varepsilon}$. Moreover, also present Beale-Kato-Majda type break-down criterion smooth solution terms mean curvature surface, gradient Taylor sign condition.

We examine the impact of corporate currency hedging on economic stability by introducing hedging activity in a Mundell-Fleming-Tobin framework for analyzing currency and financial crises. The ratio between hedged and unhedged firms is modelled depending on firm size as well as hedging costs. The results indicate that, with an increasing fraction of hedged firms in an economy, the magnitude of a...

Liu process is a new tool to deal with the noise process based on uncertainty theory. In this paper, we view the foreign exchange rate as an uncertain process, described by an uncertain differential equation driven by Liu process, and build an uncertain currency model. Then the uncertain currency option processes are discussed. Moreover, European and American currency option pricing formulas ar...
