The hypotheses of sectoral return rates on regulating capital either gravitating around or converging toward a common value is tested on data for various OECD countries by adopting two panel varying coefficient approaches. The null hypotheses receive some empirical support, which turns out to be...

The hypotheses of sectoral return rates on regulating capital either gravitating around or converging towards a common value is tested on data for various OECD countries by adopting two panel varying coefficient approaches. Our null hypotheses receive some empirical support, that turns out to be...

We test the hypotheses of industry return rates either gravitating around or converging towards a common value in Taiwan and New Zealand. We adopt various econometric approaches. The results are then nested in a meta-analytic framework together with those of the past literature. Various kinds of...

In the present paper the link between renewable energy generation and imports dynamics is explored in import demand equations. We find that renewable energy generation reduces import growth. Results display a considerable robustness.

In this paper we test for the gravitation of regulating return rates, namely those return rates yielded by capital goods incorporating the best methods of production. We define them within a vintage capital model taking into consideration capacity utilization, capital depreciation, and wages of...

This paper analyzes patterns of regional labour market development in Germany over the period 2000-2003 by means of a spatial-dependence continuous-time model. (Spatial) panel data are routinely modelled in discrete time. However, there are compelling arguments for continuous time modelling of...

We analyze the technical efficiency of German and Swiss urban public transport companies by means of SFA. In transport networks we might face different network structures or complexities, not observed, but influencing the production process. The unobserved factors are typically modeled as...
