There is a large literature on the existence of agglomeration economies, as shown in the surveys by Moomaw (1983) or Gerking (1993). The benefits of these economies arise from multiple sources, but some negative externalities might also emerge. Within the hierarchical urban system, cities at...

Forecasting regional variables provides very important information for political, institutional and economic agents. However, in the present context characterized by important decline of economies, heterogeneous data and regional interdependencies, it is even more difficult to carry out accurate...

For spatial data with a sufficiently long time dimension, the concept of global cointegration has been recently included in the econometrics research agenda. Global cointegration arises when non-stationary time series are cointegrated both within and between spatial units. In this paper, we...

In Romania, the 2008 local elections were held based on a new electoral law. The main changes concerned the election of chairpersons of county councils by uninominal voting, shifting of the general and presidential elections and the introduction of a uninominal voting system for parliamentary...

The choice of the spatial scale of analysis is a problematic issue in applied research, particularly in the literature of regional economic growth. Nevertheless, it is evident that regional scientists have been slow at demonstrating the empirical implications of changes in spatial scale of...

The production of ethanol and sugar from sugar cane has sharply increased for the last 20 years. If there are overall incentives to substitute the consumption of fossil fuels by biofuels, the increase of production and the expansion of new cultivated areas of sugar cane have eventually an impact...

This work refers to analyses of matching processes on occupational labour markets in Germany. Up to now, all studies in this field are based on the crucial assumption of separate occupational labour markets. I outlined some theoretical considerations that occupational markets are probably not...

Air quality is one of the major concerns in big cities. It is therefore of interest to evaluate properly air pollution. Specifically, this paper aims at measuring how air quality is incorporated in transaction prices in downtown Madrid. For that purpose, we use multilevel models since our sample...

The production of ethanol and sugar from sugarcane has sharply increased in Brazil in the last 20 years, in a process of substitution of biofuel for fossil fuels. The increase in the production and the expansion of the cultivated area might have impacts on human health and employment, especially...

Researchers have repeatedly noted that the results in spatial-econometric studies depend significantly on the level of regional aggregation (Jacobs-Crisioni et al., 2014; Kang et al., 2014, Baltagi, Li, 2014). Currently, hierarchical models can contribute a lot to the studies of spatial effects...
