Convergence in the OECD: Transitional Dynamics or Narrowing Steady-State Differences?
2004
I. INTRODUCTION Research on growth and convergence has proceeded through several stages that can be described as a process of accommodating cross-country heterogeneity into the convergence equation. In the first stage, the world could be described as countries approaching to equal (absolute convergence) or to different (conditional convergence) steady states. In both cases--see Baumol (1986) Barro and Sala i Martin (1992), or Mankiw et al. (1992)--the assumption of parameter homogeneity of the underlying production function was assumed and not tested. Later, some researchers (Knight et al. [1993], Islam [1995], Durlauf and Johnson [1995], or Caselli et al. [1996], among others) began to cha…
Technological differences and convergence in the OECD
2000
Abstract. In this paper we test the homogeneity of the technological parameters among OECD countries, which is the maintained hypothesis in most of the empirical growth literature. We first identify differences in the constant term of the convergence equation estimated for the OECD 1960/1990 sample using a fixed- effects estimator. Then we provide a formal test of the homogeneity of technological parameters across groups of countries. We identify at least two different groups within the OECD, with significantly different technologies. Convergence within each group is fast, supporting the notion of club convergence. Nevertheless, the implausible parameter values obtained for the leading tech…
A PROOF OF THE POWER OF KIM'S TEST AGAINST STATIONARY PROCESSES WITH STRUCTURAL BREAKS
2005
Recently, Kim (2000)1 and Busetti and Taylor (2004) have proposed different ratio-based procedures to test the hypothesis of stationarity against the alternative of changing persistence.2 This includes the alternative of a process changing from 1(0) to I(1) and vice versa, although Busetti and Taylor (2004) show that Kim's original test (2000) is inconsistent against fixed I(1) I(0) alternatives. In this note we show that, similarly to other stationarity tests (e.g., Kwiatkowski, Phillips, Schmidt, and Shin [KPSS]), Kim's test (2000) rejects the null of stationarity asymptotically with probability one, whenever the true data generating process is a stationary one around a constant term with…
