The disconnect between the exchange rate and its macroeconomic fundamentals has been extensively discussed in the literature. It nonetheless continues to pose theoretical and empirical challenges in the literature. This study examines the relationship between the exchange rate and its...

We derive the Bitcoin exchange rate dynamics by solving the exchange rate equation of the standard flexible-price monetary model to investigate any characteristics of Bitcoin like a currency. The dynamics is driven by an asymmetric mean-reverting fundamental shock which can be attributed to a...

Current views about flexible exchange rate systems are based, to a large extent, on the lessons from the period of the 1920's during which many exchange rates were flexible. This paper re-examines the evidence from the perspective of the recently revived monetary approach (or more generally,...

This study investigates why the exchange rates of oil-exporting countries do not follow the monetary model after the oil prices hikes in 2000. In empirical research, real GDP is considered as real output, while changes in oil rents are not included in GDP growth. However, in practice, oil rents...

This paper presents some models of exchange rate with jumps, namely jump diffusion exchange rate models. Jump diffusion models are quite common in computational and theoretical finance. It is known that exchange rates sometimes exhibit jumps during some time periods. Therefore, it is important...

We examine the impact of monetary injections in the Grossman-Weiss-Rotemberg Model and show that monetary shocks can lead to nominal exchange rates that are more volatile than inflation, money growth or interest rate differentials. Moreover, movements in real exchange rates following monetary...

Macroeconomic models of nominal exchange rates perform poorly. In sample, R2 statistics as high as 10 percent are rare. Out of sample, these models are typically out-forecast by a na‹ve random walk. This paper presents a model of a new kind. Instead of relying exclusively on macroeconomic...

We study the relation among exchange rates, balance sheets, and macroeconomic outcomes in a small open economy. Because liabilities are dollarized,' a real devaluation has detrimental effects on entreprenurial net worth, which in turn constrains investment due to financial frictions. But there...
