This paper argues that typical applications of panel unit root tests should take possible nonstationarity in the volatility process of the innovations of the panel time series into account. Nonstationarity volatility arises for instance when there are structural breaks in the innovation...

The paper examines the unconditional sigma and time-series convergence of real GDP per capita (measured in national currencies and euros) for CEE8 countries during the 1995 : Q1 - 2011 : Q1 period by applying the unit root framework using the DF-GLS test and the Lee and Strazicich (2003; 2004) test,...

We estimate output growth rate spectra for 58 countries. The spectra exhibit diverse shapes. To study the sources of this diversity, we estimate the short-run, business cycle, and long-run frequency components of the sampled series. For most OECD countries the bulk of the spectral mass is in the...

The existence of fluctuations is part of the narrative, especially when there is a slowdown (or worse, a contraction) in economic activity. The presence of long waves with a period of about 50 years as proposed by Kondratieff is one of the most controversial and fascinating theories about...

To date, only annual information on economic activity is published for the 16 German states. In this paper, we calculate quarterly regional GDP estimates for the period between 1995 to 2020, thereby improving the regional database in Germany. The new data set will regularly be updated when...

This paper tried to examine the level of cointegration among various nations across the continents in regard to the globalisation. Also here attempt is made to analyse the nature of inter and intra continental variation in globalisation over time. The proximity and convergence over time in terms...

This paper measures the size and composition of non-tariff trade costs such as transport, wholesale, and network costs incurred in Canada's merchandise trade using Statistics Canada's latest 'trade margins' statistics. It examines how changes in these trade costs have influenced Canada's...
