This paper investigates the relationship between consumer credits and interest rates in Turkey based on the fractional cointegration approach by using daily observations over the period from 4 January 2002 to 24 December 2010. First, we ignore the possible structural breaks in the series and perform the Geweke and Porter-Hudak (GPH) test on the residuals for fractional cointegration. Second, we...

This paper examines the dynamic behavior of relative prices across seven Australian cities by applying panel unit root test procedures with structural breaks to quarterly CPI data for 1972Q1-2011Q4. We find overwhelming evidence of convergence in city relative prices. Three common structural breaks are endogenously determined at 1985, 1995, and 2007. Further, correcting for two potential biases...

We analyze the issue of the impact of multiple breaks on monetary neutrality results, using a long annual international data set. We empirically verify whether neutrality propositions remain addressable (and if so, whether they hold or not), when unit root tests are carried out allowing for multiple structural breaks in the long-run trend function of the variables. It is found that conclusions ...

In this paper, several seasonal unit root tests are analysed in the context of structural breaks at known time and a new break corrected test is suggested. We show that the widely used HEGY test as well as an LM variant thereof are asymptotically robust to seasonal mean shifts of finite magnitude. In finite samples, however, experiments reveal that such tests suffer from severe size distortions...

This paper studies a representative-agent asset-pricing model of an endowment economy in which the agent has incomplete knowledge about exogenous stochastic endowment process and has incentive to learn about the process with adaptive learning rules. There is the well documented fact that when underlying economic environment is known and is common knowledge to investors, asset-pricing models und...

We propose a class of new robust Generalized Method of Moments (GMM) tests for endogenous structural breaks. The tests are based on supremum, average and exponential functionals derived from robust GMM estimators with bounded influence function. We study the theoretical local robustness properties of the new tests and show that they imply a uniformly bounded asymptotic sensitivity of size and p...

This paper examines the predictive content of coincident variables for monitoring U.S. recessions in the presence of instabilities. We propose several specifications of a probit model for classifying phases of the business cycle. We find strong evidence in favor of the ones that allow for the possibility that the economy has experienced recurrent breaks. The recession probabilities of these mod...
