Exploring the sources of labour productivity growth and convergence in the Italian regions: some evidence from a production frontier approach

2009

This paper investigates labour productivity growth and regional convergence patterns in Italy over the time span 1982–2000. Starting from some evidence of spatial polarisation within Italian economy, the analysis aims at exploring the sources of this tendency. To this end, an approach based on data envelopment analysis (DEA) production frontiers is employed which allows to decompose labour productivity growth into efficiency change, technological progress and capital deepening, looking then at the relative contribution of each component to regional convergence. Moreover, some measures of human capital and public capital are used as augmentation factors of the conventional inputs. The study …

Efficiency, costs and market power analysis of the Spanish Port System

2021

El presente trabajo tiene diferentes objetivos. El primero es calcular la eficiencia técnica de las autoridades portuarias en la prestación de servicios sobre tráfico de mercancías y pasajeros en el periodo 2002- 2018. Para llevar a cabo este objetivo, se utiliza una función distancia orientada al output y se estima la eficiencia técnica a partir de una función frontera del tipo estocástico (SFA). Del mismo modo, se emplea la metodología no paramétrica (DEA) bajo dos supuestos alternativos, o bien bajo rendimientos constantes a escala (modelo de Charnes, Cooper y Rhodes, 1978), o bien bajo rendimientos variables a escala (modelo de Banker, Charnes y Cooper, 1984). Este análisis nos permite …

PROFITABILITY A SUBSYSTEM WITHIN THE GENERAL SYSTEM OF ECONOMIC EFFICIENCY FOR AGRICULTURAL EXPLOITATIONS

2013

Under market economy conditions purchasing profitability represents a rule for each and every market player. It represents an essential condition of the existence of economic units. Survival of the enterprise and assuring its profitability are “the first concerns of every skilled leader. They are valid in each and every moment, right from the enterprises foundation. Thus profitability is a tool for decision making regarding internal administration of the economic unit, as well as in relation to external partners. It is the synthetic expression of results of any nature, an index for decision making and entity behaviour.

Organization and efficiency of education systems : some empirical findings

2000

International audience; Using a sample of countries chosen for their similar level of development, this article shows the extent to which the organisation of primary and secondary education differs from one country to another, notably with respect to the way in which systems differentiate and select pupils for specialised curricula. It also explores the question of whether an education system that sorts pupils at a very early age is more cost-effective than a system that does not sort pupils during compulsory education. The stylised description of national education system is based on various sources of information. The data used in the cost analysis come from OECD and UNESCO. Due to data l…

The Analyses of the Teacher’s Activities Facing with Efficiency

2008

The element of education has here a very important role not only regarding the aspect of quality of the act but in integrating the need of quality in the national culture. The individual’s conception has to assimilate the conviction that the welfare can not exist without a responsible and quality labor. Starting form this mission, it becomes obvious that the entire university’s activity should be oriented towards the institution’s competitiveness growth both at a national level and at the international level through: the quality of the offer and the result of the activity, a good management, a financial politic adequate to the rational use of the resources and of drawing new resources, to s…

Educational Efficiency in a Dea-Bootstrap Approach

2010

We use the PISA 2006 results to analyse the students' proficiencies in 24 European Countries with regard to two indexes that represent the educational resources available at home and the family background of students. Many factors affect the proficiencies and therefore, using a DEA-bootstrap method, we intend to measure the efficiency of the European educational systems as capability to ensure high students' competencies despite adverse conditions about the educational resources available in students' home and the family background.

Eco-efficiency assessment of municipal solid waste services: Influence of exogenous variables.

2020

Abstract Improving the eco-efficiency of municipalities in the provision of municipal solid waste (MSW) services is fundamental in the context of a circular economy. This study evaluates the eco-efficiency of a sample of Spanish municipalities, integrating the total cost as input, recyclable waste as desirable output, and unsorted waste as undesirable output. Following a pioneering approach, the weighted Russell directional distance model (a non-radial data envelopment analysis model) was employed, which allowed us to obtain a global inefficiency score and individual inefficiency scores for each variable integrated in the model. In the second stage of analysis, the potential factors affecti…

Causes of Public Expenditure Inefficiency and Proposals for Their Streamlining

2020

The public sector has continually developed, as new needs of the population have been identified and the expectations of the population regarding the quantity and the quality of the provided services have already been rising. Unlike private management, the public administration has not always been concerned with the way results have been achieved, but, particularly with the results themselves, and, as long as these have been satisfying for the population, the resources employed for obtaining the results were of no much concern. The public administration monopoly in the provision of some services has led to the possibility of generating imbalances between the quality of the provided services…

Differential Translational Efficiency of the mRNAs Isolated from Derepressed and Glucose Repressed Saccharomyces cerevisiae

1987

Summary: Carbon catabolite derepression induced changes in the pool of yeast mRNAs translatable in a protein-synthesizing reticulocyte system. Competition experiments with globin mRNA showed that the mRNA population obtained from derepressed cells possessed a higher translational efficiency than mRNA from repressed cells. The mRNAs that could account for the high translational efficiency of the derepressed mRNA were not detected in cells growing in glucose-rich medium. Analysis of protein synthesis in the presence of 7-methylguanosine 5′-phosphate indicated that the initiation factors recognizing the 5′-terminal structure of capped messengers interacted with lower affinity with the represse…
