Traditional economic theory, up to the middle of the twentieth century, builds up the production functions regardless of the inputs’ scarcity. In the last few decades it has become clear that in many cases inputs are depletable quantities and at the same time a lot of constraints are imposed...

Modern microeconomics and macroeconomics study dynamic phenomena. Dynamics could predict future states of an economy based on its structural characteristics. Economic dynamics are modeled in discrete and continuous time context, mainly via autonomous difference and differential equations. In...

This paper by applying a sporting production function evaluates 229 professional tennis players’ career performance. By applying Data Envelopment Analysis (DEA) the paper produces a unified measure of nine performance indicators into a single career performance index. In addition bootstrap...

In this paper we set up an oligopolistic market model, where firms invest in pollution abatement in order to increase the whole market size via an increase in the consumers’ reservation price. Moreover, we suppose that the demand function is not a linear one and the resulting game is not a...

Marine and coastal ecosystems are of high importance owing to the mankind dependence on the goods and services provided. As water quality is one perspective of healthy marine and coastal ecosystems, the aim of this study is to review as more as possible surveys conducted worldwide and in Greece....

This paper proposes a conditional directional distance function model in order to examine the link between regional environmental efficiency and GDP per capita levels. As an illustrative example we apply our model to USA regional data revealing an inverted ‘U’ shape relationship between...

In this study, a basic comparison between the Pigouvian and the Coasean approaches is carried out in order to discuss and comment on the mechanisms by which externalities are resolved. Environmental control approaches are examined and compared in terms of minimization of abatement costs,...

Examining the identification problem in the context of a linear econometric model can be a tedious task. The order condition of identifiability is an easy condition to compute, though difficult to remember. The application of the rank condition, due to its complicated definition and its...

Computations with large matrices work out faster with computer software, even faster creating automatically the matrix of the size and pattern needed. In this paper we propose free computer algebra system Xcas resources to display particular matrices that can be called up directly. Our computer...

This paper examines the relationship between renewable energy consumption and economic efficiency. For this reason conditional Data Envelopment Analysis (DEA) estimators alongside with nonparametric regressions are applied in a sample of 25 European countries for the year 2010. Our results...
