The Envelope Theorem is shown to involve comparaisons between the performance of the optimal policy and that of alternative policies, which satisfy the constraints of the problem and may also have other features.

The paper considers Caratheodory's Theorem on the properties of the Inverse of the Bordered Hessian of an Optimization Problem. After a new proof of the complete theorem, using matrix theory methods, the paper considers the sensitivity of the optimal solution in parameters appearing either in...

The Envelope Theorem is showm to involve comparisons between the performance of the optimal policy and that of alternative policies, which satisfy the constraints of the problem and may also have other features. The theorem is activated whenever parameter values are such that the extreme value...

The aim of this study is to identify and quantify factors which influenced exporting firms' performance during the last global financial crisis. A structured questionnaire is utilized to interview a sample of Greek exporters. The survey generated a unique dataset describing the firms'...

In order to make possible an economic estimation of industrial pollution, which is one of the main polluters in the Asopos River Basin (RB), another method that of Benefit Transfer (BT) was applied and is presented in this chapter. The fact that gathering primary site-specific data is costly and...

In this paper, one of the basic assumptions is that the environment provides two different kinds of services. First, the environment may serve as an input to the production of conventional goods. For example, the exploitation of an oil source from which one firm extracts the oil which in turn is...

In this paper we employ a choice experiment (conducted in Ukraine and Turkey) on the valuation of a marine restoration programme in the Black Sea, to examine whether the value of environmental goods is sensitive to the source of public financing. We contribute to the debate on the optimal...
