The presence of negative values in the primary inputs vector in the input output framework has been considered as a limitation to the development of multi-sectoral linear models. It is true that, when this circumstance happens, the industries that are related appear unbalanced, however, the...

En el presente trabajo se desarrolla un estudio de las emisiones de CH4 relacionadas con el sector agroalimentario catalán a través de un análisis alternativo, o al menos complementario, de subsistemas input-output. Una herramienta de gran utilidad para estudiar la estructura productiva de...

The presence of negative values in the primary inputs vector in the input output framework has been considered as a limitation to the development of multi-sectoral linear models. It is true that, when this circumstance happens, the industries that are related appear unbalanced, however, the...

There is a regional input-output table for Córdoba, an Argentinian province, estimated by survey techniques. In this paper, non-survey techniques are tested, through the FLQ and ALFQ location quotients, using different values of δ, a parameter that appear in these formulas. The aim of this...

The input output analysis is used by a lot of cities with the objective to study interregional trade problems. We focused our work on Argentina, and we present a model with two regions: Buenos Aires city and the rest of the country. Buenos Aires does not have an Input Output Tables or a regional...

In this paper we extend the proportional rule to division problems with multiple references and we present a result of characterization of the weighted proportional rule. As a particular case, we analyze the problems of probability aggregation and probability updating. division problems with...

Social accounting matrices are an instrument that allow us to enlarge information provided by the input-output analysis when studying the intersectorial relationships of an economy, the behavior of consumers, the public sector or the foreign sector; while being able to complete the income flow...

El objetivo que se plantea en este trabajo es el de identificar los sectores clave y estratégicos para el desarrollo de economías a nivel regional y su comparación con el paradigma nacional. Para ello, se aplican diversas metodologías complementarias de análisis de sectores clave para las...

El objetivo de este estudio es analizar el impacto, en emisiones de CO2, de la demanda final de Cataluña en relación a los vínculos comerciales interregionales con el resto de España y el resto del mundo. Este proceso implica el análisis del balance en CO2 incorporado para Cataluña, lo que...

Se demuestra que todo sistema tipo Leontief (o Leontief-Sraffa) puede ser transformado en uno estructuralmente equivalente en el que la matriz tecnológica A tenga la propiedad de que la suma de los elementos de cada columna sea el autovalor máximo a de A; lo que equivale a transformar las...
