The nonlinear behaviour of four coffee price series is examined, that is, unwashed Arabicas (i.e. coffee from Brazil), Colombian Mild Arabicas (i.e. coffee from Colombia), other Mild Arabicas (i.e. coffee from other Latin American countries), and Robusta coffee (i.e. coffee from Africa and...

This paper estimates an asymmetric error correction model to analyse the dynamic behaviour of the Colombian unemployment rate. It is found that wages above their long-run equilibrium level do increase unemployment, but wages below this level do not reduce it. This finding provides evidence of...

We employ parametric and nonparametric cointegration approaches to investigate the extent of integration between African stock markets and the rest of the world. Long-run correlation estimates imply very low association between these two. The two distinct cointegration approaches confirm the...

This article tests for stock market efficiency among 12 Asia-Pacific countries. A novel approach is applied where unit-root tests of real stock prices are embedded within a Markov regime-switching framework. Although standard univariate unit-root tests provide little support for stock price mean...

Markov regime-switching analysis is used to consider the relationship between business confidence and the probability of turning points in cyclical GDP. We find, in an application to New Zealand, that confidence is related to both the deepness and duration of the business cycle and is asymmetric...
