To do this, our analysis is based on three evaluation methods that allow us to conclude that the exchange rate channel is better evaluated by the non-linear approach of the countries studied. Thus, the depreciation of the exchange rate adopted by the countries of the Med zone did worse macroeconomic stability and economic convergence.展开更多

Consequently, the fact that the specific activity of the acid increased withtime was obtained, and the T-for-H exchange reaction occurred. By applying the A"-McKay plot method to the dataobserved, the rate constant of each functional group for the reaction was obtained. After the additive property of theHammett’s rule was applied to this work, the new substituent constants were obtained. From the above-mentioned,the following four items have been confirmed: (1) the reactivity of the functional groups can be dynamically analyzed,and the A"-McKay plot method is useful to analyze the reactivity; (2) the additive property of the Hammett’s rule isapplicable to quantitative comparison of the reactivity of the functional groups; (3) the reactivity of the functionalgroups can be simultaneously analyzed by using the A"-McKay plot method in the T-H exchange reaction; and (4) themethod used in this work is also useful for analyzing the reactivity of a certain material having some kinds of functional groups.展开更多

With the interval method, interval sample data are formed to present the volatility of variables. The ILS approach is extended to multi-model estimation and the computational schemes are provided. The empirical evidence suggests that the ILS estimates well characterize how the exchange rate relates to the gold price, both in the long-run and short-run. The comparison between the interval and point methods indicates that the difference between the OLS and the ILS estimates is increasing from weekly data to quarterly data, since the lowest frequency point data lost the most information of volatility.展开更多

Greater exchange rate flexibility is often suggested as a means to achieve faster and more efficient adjustment in the current account. However, previous empirical studies show little support for this hypothesis. This paper revisits this issue with a large panel dataset and a threshold VAR model and finds that （1） some existing popular exchange rate classifications may not capture actual exchange rate variability as well as expected; （2） Once exchange rate variability is correctly identified, the speed of mean reversion in the current account balance is indeed higher in a regime with greater exchange rate variability.展开更多
