In this paper we apply two methodologies to the measurement of efficiency in Portuguese Universities. These are a stochastic frontier parametric method and a non-parametric DEA method. We produce results from both methods in terms of efficiency estimates for each university over the period 2003...

Research on productive efficiency at the firm level has developed as an important and active strand of research the last decades, both within operations research, management science and economics. However, the interests pursued within the fields have had some differences regarding sound...

Agricultural inputs are peculiar in nature as an asymmetry in their roles can be identified during the production process. These inputs can be grouped into a set of growth inputs or a set of facilitating inputs. The inputs affecting biological or physiological growth from the inside of the plant...

Levels of CO2 emissions from electricity generation in the U.S. have changed considerably in the last decade. This development can be attributed to two factors. First, the shale gas revolution has reduced gas prices significantly, leading to a crowding out of the more CO2-intensive coal for...

We consider efficiency measurement methods in the presence of uncertain input and output data, and without the (empirically problematic) assumption of convexity of the production technology. In particular, we perform a simulation study in order to contrast two well-established methods, IDEA and...

Despite progress over the past two decades Mexico?s health and education indicators remain well below the average of the OECD and some of its Latin American emerging market peers. Health insurance coverage is incomplete, especially for low-income families, and access to health services is highly...
