System of panel models are popular models in applied sciences and the question of spatial errors has created the recent demand for spatial system estimation of panel models. Therefore we propose new diagnostic methods to explore if the spatial component will change significantly the outcome of...

This paper analyses a new framework for decision-making in e-democracies that exploits the power of Internet based public knowledge, which is called briefly e-cognocracy. This is not a procedure to improve technical aspects using the Internet (e.g. e-voting); it is rather a procedure to add a...

We analyze the performance of the Maastricht convergence criteria (inflation, long-term interest rate, annual and overall public debt) of the European Monetary Union (EMU) that led to the introduction of the Euro on Jan. 1st 1999 as book currency. Defining 3 regimes, 1992-97, 1997-1999 and...

In a simple growth model we explore the current and future growth effects of the regional population structure. Regional GDP growth in 227 regions within six countries in central Europe is explored as how they depend on the young and old dependency ratio. The young dependency ratio (YDR) is...

This paper develops a new approach for a political support system related to the integration of immigrants using e-governance. Through the Internet the participation of immigrants is possible in both societies, the original and the new one, and at the three different levels: local, regional and...

We introduce a regression-based gravity model for commodity flows between 35 regions in Austria. We incorporate information regarding the highway network into the spatial connectivity structure of the spatial autoregressive econometric model. We find that our approach produces improved model fit...
