Hysteresis in a simple model of currency substitution
نویسنده
چکیده
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 dominate the foreign currency in rate of return to induce agents to stop using the foreign currency. Finally, in ation rates that trigger currency substitution need not be associated with steady states in which the domestic currency disappears from circulation.

Discussion Paper Series The Effects of Uncertainty on Currency Substitution and Inflation: Evidence from Emerging Economies
This paper examines the effects of inflation and currency substitution volatility on the average rates of inflation and currency substitution for twelve emerging market economies. Using a bivariate GARCH-in-Mean model, which accommodates for asymmetric and spillover effects of inflation and currency substitution innovations on their volatilities, we find that for the majority of the countries i...
متن کاملDynamic Performance Analysis of Hysteresis Motors by a Linear Time-Varying Model
Hysteresis motors are self starting brushless synchronous motors which are being used widely due to their interesting features. Accurate modeling of the motors is crucial to successful investigating the dynamic performance of them. The hysteresis loops of the material used in the rotor and their influences on the parameters of the equivalent circuit are necessary to be taken into considerat...
متن کاملThe Impact of Exchange Rate on Demand for Money in Iran
Abstract: Central banks have long been interested in obtaining precise estimations of money demand given the fact that the evolution of money demand plays a key role over several monetary variables. One implication of currency substitution is that the exchange rate could serve as another determinant of the demand for money. Due to the recent currency crisis in Iran, it would be important to inv...
متن کاملDollarization Traps *
The paper analyzes dollarization in the sense of asset substitution, where a foreign currency competes with local assets, especially domestic capital, as a store of value, the impact of dollarization on capital accumulation and output, and why economies remain dollarized long after a successful inflation stabilization. We relate this dollarization hysteresis to a financial intermediation failur...
متن کاملA Simple Theoretical Model for Prediction of Phase Inversion
Phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between Oil-in-Aqueous dispersion and Aqueous-in-Oil dispersion. A theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. Experimental data from the literature were used to validate the model and results were c...
