In this paper we do not attempt to develop an interregional model. Rather, we propose a mathematical structure of computational framework with which a family of interregional input-output models can be constructed. This family of interregional input-output models encompasses the well-known class of static models that are used to analyse the propagation of demand throughout an economic system di...

Maintenance of aging legacy COBOL systems is labor-intensive and is becoming a more and more difficult problem. Program slicing is a potentially useful analysis for aiding different maintenance activities, including program comprehension, reverse engineering, debugging, and testing. Numerous techniques have been proposed in the past decades; however, in interactive contexts, we found none of th...

Understanding the drivers of changes in CO2 emissions is vital for a range of stakeholders. Hence, this paper explores the main drivers of CO2 emissions in China using structural decomposition analysis based on constant price and non-comparative input-output tables. The driving forces at both nationwide and industrial levels are divided into nine effects. To investigate the effects from an ener...

Many archives have introduced online archival databases in the past few years. However, apart from being independent of place and time, hardly any of these databases make finding records any easier than it was before. This paper suggests to put more emphasis on the needs and behavior of users and to provide them with the context in which records were created, thus making it possible to link arc...

The Leontief model is generally considered as belonging to the category of the production-prices models , aside of the Ricardian, Marxian and Sra aian models. This paper clearly demonstrates that this is a super cial point of view. As the Leontief model handles price indexes, it is biperiodic: the Leontief price indexes solve the model for the base time period. The production-prices model that ...

Wassily Leontief jun. (1905–1999) moved to Berlin in April 1925 after getting his first academic degree from the University of Leningrad. In he mainly studied with Werner Sombart and Ladislaus von Bortkiewicz who were referees Ph.D. thesis “The economy as a circular flow” (1928). From spring 1927 until 1931 was member research staff at Kiel Institute World Economics, interrupted by period 1929 ...

We study the problem of allocating multiple resources to agents with heterogeneous demands. Technological advances such as cloud computing and data centers provide a new impetus for investigating this problem under the assumption that agents demand the resources in fixed proportions, known in economics as Leontief preferences. In a recent paper, Ghodsi et al. [2011] introduced the dominant reso...
