Cointegrating smooth transition regressions with applications to the Asian currency crisis

Saikkonen, Pentti; Choi, In - 2000

This paper studies the smooth transition regression model where regressors are I(1) and errors are I(0). The regressors and errors are assumed to be dependent both serially and contemporaneously. Using the triangular array asymptotics, the nonlinear least squares estimator is shown to be...

Modelling exchange rates volatility with multivariate long-memory ARCH processes

Teyssière, Gilles - 1999 - Rev.

We consider two multivariate long-memory ARCH models, which extend the univariate long-memory ARCH models, we first consider a long-memory extension of the restricted constant conditional correlations (CCC) model introduced by Bollerslev (1990), and we propose a new unrestricted conditional...

The monetary model of the exchange rate : a structural interpretation

Moersch, Mathias; Nautz, Dieter - 1998

We emphasize the importance of properly identifying the long-run relations underlying the monetary model of the exchange rate. The separate estimation of long-run money demands leads to a "structural" error correction equation which allows an interpretation of the various channels affecting the...

The empirical determinants of the Euro : short and long run perspectives

Chinn, Menzie David - 2000

The behavior of the dollar/euro exchange rate is modeled using a monetary model of the exchange rate. The econometric analysis is complicated by the short sample span of actual euro data available for analysis. Hence, data on a "synthetic" euro are used. The assumptions underlying the monetary...

The Polish crawling peg system : a cointegration analysis

Trenkler, Carsten - 2000

After a temporary period of a fixed exchange rate regime pegging the Polish zloty to the U.S. dollar, Poland established a preannounced crawling peg regime on October 15, 1991. In this system the zloty is tied to a currency basket and devalued with a preannounced monthly rate (rate of crawl). If...
