It has been claimed that the deviations from purchasing power parity are highly persistent and have quite long half-lives under the assumption of a linear adjustment of real exchange rates. However, inspired by trade cost models, nonlinear adjustment has been widely employed in recent empirical...

This paper considers the test of a unit root in transitional autoregressive models. In particular, we develop the asymptotic theory of the inf-t test for the null hypothesis of a unit root in a wide class of nonlinear autoregressive models having parameters that are identified only under the...

This paper proposes a new test for the presence of a nonlinear deterministic trend approximated by a Fourier expansion in a univariate time series for which there is no prior knowledge as to whether the noise component is stationary or contains an autoregressive unit root. Our approach builds on...

The Great East Japan Earthquake in 2011, as well as the Great Hanshin-Awaji Earthquake in 1995 and the Great Kanto Earthquake in 1923, resulted in disorderly movements of yen in the foreign exchange market. This paper investigates the exchange rate volatility shift after these three great...

This paper investigates the relationship between the exchange rate pass-through (ERPT) and inflation by estimating a nonlinear time series model. Based on a simple theoretical model of ERPT determination, we show that the dynamics of ERPT can be well approximated by a class of smooth transition...

This paper proposes a fully nonparametric test for cointegrating rank which does not require estimation of a vector autoregressive model. The test exploits the fact that the degeneracy in the moment matrix of the variables with mixed integration order corresponds to the notion of cointegration....

Data from Okinawa's monetary union with the United States in 1958 and with Japan in 1972 are used to obtain a quantitative indication of how monetary union might affect the behavior of nominal and real shocks across two economies. With monetary union, the variance of the real exchange rate...
