This discussion focuses on threshold nonstationary–nonlinear time series modelling; it raises various issues to do with identifiability and model complexity. It also gives some background history concerning smooth threshold/transition autoregressive models and hidden Markov switching models....

This study employs the multivariate threshold model developed by Tsay (1998) to examine the effects of international and domestic oil prices on the price indices in Taiwan using monthly data from January 1999 to December 2011. The results show that changes in domestic oil prices do not Granger...

Although the spread has been established as a leading indicator of economic activity, recent studies on US and EU countries have documented, theoretically and empirically, that the term spread-output growth relationship may not be stable over time and it may be subjected to nonlinearities. Using...

There have been several instances over the past 40 years when large movements in the unemployment rate have elicited little response in the inflation rate. Such instances, while casting doubt on the tradeoff implied by the linear Phillips curve, are also associated with large inflation...

This paper explores the two-way relationships between Economic Growth (EG) and Human Development (HD), building on an earlier work by Ranis, Stewart, and Ramirez (2000). Here, we show that HD is not only a product of EG but also an important input to it. The paper develops new empirical...
