The linear Gaussian state space model for which the common variance istreated as a stochastic time-varying variable is considered for themodelling of economic time series. The focus of this paper is on thesimultaneous estimation of parameters related to the stochasticprocesses of the mean part...

We investigate changes in the time series characteristics of postwar U.S. inflation. In a model-based analysis the conditional mean of inflation is specified by a long memory autoregressive fractionally integrated moving average process and the conditional variance is modelled by a stochastic...

The number of short-time workers from January to April 2020 is used to now- and forecast quarterly GDP growth. We purge the monthly log level series from the systematic component to extract unexpected changes or shocks to log short-time workers. These monthly shocks are included in a univariate...

The number of employees historically filed and registered from January to April 2020 for short-time compensation is used to obtain a nowcast for GDP growth in the first quarter and an outlook until the third quarter 2021. We purge the monthly log level series from the systematic component to...

The balanced growth theory and the neoclassical growth model predict that certain macroeconomic variables such as output, consumption, and investment grow at a constant rate. Analytically, it indicates that the consumption-output ratio and the investment-output ratio (termed "great ratios") must...

We study the structure and dating of disaggregated Indian industrial cycles and spectral causality from different policy parameters to these cycles. The scattered pattern of peaks and troughs after 2013, suggests some industries continued to do well during an extended slowdown. Post 2011...
