The real exchange-rate puzzles is a common term for two much-discussed anomalies of real exchange rates: that real exchange rates are more volatile and show more persistence than what most models can account for. These two anomalies are sometimes referred to as the purchasing power parity puzzles.
The exchange rate disconnect puzzle: The exchange rate disconnect puzzle, also one of the so-called real exchange rate puzzles, concerns the weak short-term feedback link between exchange rates and the rest of the economy. In most economies, the exchange rate is the most important relative price, so it is surprising, and thus far unexplained ...
In economics, the Backus–Smith puzzle or consumption – real-exchange-rate anomaly is the observation that the correlation between consumption and real exchange rates is zero or negative. This is contrary to economic theory which predicts that with full risk sharing, relative consumption should be perfectly correlated with the real exchange ...
While one version of the impossible trinity is focused on the extreme case – with a perfectly fixed exchange rate and a perfectly open capital account, a country has absolutely no autonomous monetary policy – the real world has thrown up repeated examples where the capital controls are loosened, resulting in greater exchange rate rigidity ...
William Huskisson, Question concerning the depreciation of our currency, 1810. Currency depreciation is the loss of value of a country's currency with respect to one or more foreign reference currencies, typically in a floating exchange rate system in which no official currency value is maintained.
A currency crisis is normally considered as part of a financial crisis. Kaminsky et al. (1998), for instance, define currency crises as when a weighted average of monthly percentage depreciations in the exchange rate and monthly percentage declines in exchange reserves exceeds its mean by more than three standard deviations.
The exchange rate is also regarded as the value of one country's currency in relation to another currency. [3] For example, an interbank exchange rate of 141 Japanese yen to the United States dollar means that ¥141 will be exchanged for US$1 or that US$1 will be exchanged for ¥141. In this case it is said that the price of a dollar in ...
Suppose initially the US exports 60 million tons of goods to Japan and imports 100 million tons of other goods under an exchange rate of $.01/yen and prices of $1/ton and 100 yen/ton, for a trade deficit of $40 million. The initial effect of dollar depreciation to $.011/yen is to make imports cost $110 million, and the deficit rises to $50 million.
