This paper examines the properties of the two recent structural break unit root tests developed in Harvey, Leybourne and Taylor (2013) and Narayan and Popp (2010). The properties are investigated by Monte Carlo simulations in an environment where two trend breaks of small to large magnitudes are present. We find that the Harvey, Leybourne and Taylor (2013) test has superior size and power prope...

abstract in this paper we test two versions of convergence hypothesis namely deterministic or conditional convergence and stochastic or catching up hypothesis using carrion-i-silvestre et al. (2005) stationary test. the results show latin and south american countries (lsa) catching up process toward the usa failed in 1980s and somewhat in 1990s. but in 2000s most of them could lie in convergenc...

Transvection Interactions between mutant alleles typically depend upon diffusible factors. However, transvection must depend upon pairing, because when either allele is present on a structurally rearranged chromosome (such as a Steven Henikoff* and Luca Comai† *Howard Hughes Medical Institute Fred Hutchinson Cancer Research Center 1100 Fairview Avenue North Seattle, Washington 98109-1024 †Depar...

In this paper, a synthesis of the recently advanced Lagrange multiplier (LM)-based tests for the null of no cointegration which account for different patterns of breaks in the cointegrating relationship is provided. The limiting distributions of the test statistics are not only invariant to an intercept break and a break in the cointegrating vector, but are also invariant to a trend break in a ...

Abstract: Many empirical studies have indicated that inflation exhibits very high persistence throughout the post-war period in nearly every industrial economy. In this paper we challenge this conventional wisdom and instead argue that in many cases, high inflation persistence is an artifact of empirical techniques that fail to account for occasional shifts in the monetary policy regime. In par...

In this paper we consider the problem of determining the number of structural changes in multiple linear regression models via group fused Lasso (least absolute shrinkage and selection operator). We show that with probability tending to one our method can correctly determine the unknown number of breaks and the estimated break dates are sufficiently close to the true break dates. We obtain esti...
