Panel data are specific data where cases are observed at two or more time periods. This approach brings many advantages: larger dataset, decreasing collinearity between exogenous variables and using advanced econometric models. The panel data models were applied to data from the Household Budget...

Panel data are a result of repeating observations of a group of units, e.g. households, firms, but also whole economies with some common characteristics as EU15, transition economies a . s. o. So, more details are available enabling to analyze a changing economic structure and its reasoning....

Panel data are increasingly being used in both macro- and micro-level studies of economic problems. Macro-panel data (i denotes countries) are characteristic by sufficiently long time series to be able to analyze panel spurious regression and panel cointegration. According to the main stream of...

We consider two markets in our model: wholesale, where producers' supply interacts with distributors' demand, and retail with distributors' supply and consumers' demand. The wholesale market determines the producer price index (PPI), production and indirectly also employment. In the retail...

Extreme value theory is the most scientific approach to an inherently difficult problem - predicting the possibility that an extreme event will occur. Broadly speaking, there are two kinds of models for extreme values. The first group of models are models for a distribution of normalized maximum...

The paper examines implications of both real and nominal convergence for a fully-funded pension system. The process of convergence implies that higher contribution rates are necessary in the converging economy for replacement ratios to be the same as in a steady-state economy. This effect in the...

The paper deals with a wide-spread myth that a switch from a PAYG to a funded pension system might solve adverse consequences of the population aging. It is shown, that under additional assumptions the pension debt (which is created during the process of the switch) is exactly equal to the value...
