In the present paper we consider the general class of first-order nonlinear models. The main contributions concern primerly a generalization of the conditions for geometric ergodicity presented in Ferrante et al. (2003). The obtained result is then applied to two classes of first-order nonlinear...

This article builds on the recent policy diffusion literature and attempts to overcome one of its major problems, namely the lack of a coherent theoretical framework. The literature defines policy diffusion as a process where policy choices are interdependent, and identifies several diffusion...

We study the role of governance regimes in the determination of corruption and economic growth. Our model identifies two governance regimes and shows that the relationship between corruption and growth is regime specific. We use a threshold model to estimate the impact of corruption on growth...

Inferences about the presence or absence of threshold type nonlinearities in TAR models are conducted within models whose lag length has been estimated in a preliminary stage. Typically the null hypothesis of linearity is then tested against a threshold alternative on which the estimated lag...

We examine potential nonlinear behaviour in the conduct of monetary policy by the Bank of England. We find significant nonlinearity in this policy setting, and in particular that the standard Taylor rule really only begins to bite once expected inflation is significantly above its target. This...

This paper employs both linear and non-linear models to investigate the relationship between national defense spending and economic growth for Taiwan and China. Using data from 1953-2000 on defense spending, GDP, import, export and capital, we find that China's defense spending leads that of...
