In this paper, a theoretical relationship is obtained to measure the effect that inefficiency has on marginal costs, degree of economies of scale and technical change. It is shown that when the relationship between inefficiency and output level is ignored, the estimation of marginal costs and...

The term ”wavelets” covers a set of resources from the mathematical analysis that have proven their efficiency in system identification on areas such as hydrology, geology, glaciology, climatology and energy resources optimization. The methodology undergone on systems engineering could be...

In this paper we have built a theoretical model using a normalized quadratic cost system to obtain expressions for actual input demand and cost as functions of three components: frontier, allocative and technical inefficiency. We have used the shadow prices approach in the line of exact...

Port infrastructure has characteristics that are classified by quasi-fixed inputs, meaning they cannot be immediately adjusted, contributing to the production of transport services over long periods of time. Another important characteristic of port infrastructure is that its current technology...

The economy of the Canary Islands has experienced significant macroeconomic adjustment and real convergence with the European Union, being the tax and economic specificities established in its special Economic and Fiscal Regime (REF) one of the main driving forces. In this paper, we have...
