This paper proposes an efficient estimation method for Band Threshold Autoregressive (Band-TAR) models. Standard maximum-likelihood algorithms cannot be used here because the log-likelihood function is not differentiable with respect to the threshold parameter, and one commonly uses a grid...

This study indirectly addresses the issue of potential nonlinearities in real exchange rate adjustment for 18 OECD economies 1973-1998 using recent developments in the theory of nonparametric cointegration. While the standard Johansen tests yield mixed evidence, the results from a new...

Using threshold autoregressive specifications, this paper develops new parametric tests for level asymmetries. It proposes bootstrap likelihood ratio statistics to test the symmetric adjustment null against sign and amplitude asymmetries or a combination of both. Monte Carlo simulations show...

The short-run dynamics of German mark and US dollar real exchange rates are investigated for a panel of 19 OECD economies in a vector error correction framework for the 1973-96 period. The novel persistence profiles approach of Pesaran and Shin (1996) indicates that the effect of system-wide...

Empirical studies have had difficulty in establishing the long-run relationship between real exchange rates and real yield differentials predicted by sticky price exchange rate models. We revisit this issue in a nonstationary panel regression framework. This facilitates estimation of a long-run...
