This paper presents new results of mathematical modeling of economy and environment interaction. A model of mutual interaction of livestock farming - one in a two main agricultural branches - and natural pastures that are the essential part of livestock farming forage reserve is proposed....

This paper shows the characteristics of the macroeconomic Social Accounting Matrix (SAM) of Tunisia in 1996. It is established that the SAM is one of the data bases of the Computable General Equilibrium (CGE) Models. These last years, the researchers have intensified the use of the SAM within...

This paper has the aim to present the various methods of balancing applied to the macroeconomic Social Accounting Matrix (macro SAM) of Tunisia during the year 2000. These methods (method of entropy, method of least squares....) were used by the modellers of Computable General Equilibrium (CGE)...

Through the use of aggregate Social Accounting Matrices for Portugal, the flows of funds from three government subsectors to households will be studied, as well as the flows from the latter to the former. From the SAM modelling, both a static and a comparative static analysis will be made, in...

Isard’s vision of integrated modeling that was laid out in the 1960s book Methods of Regional Science provided a road map for the development of more sophisticated analysis of spatial economic systems. Some forty years later, we look back at this vision and trace developments in a sample of...

Ecological economics is a transdisciplinary alternative to mainstream environmental economics. Attempts have been made to outline a methodology for ecological economics and it is probably fair to say that, at this point, ecological economics takes a “pluralistic” approach. There are,...

Public opinion surveys conducted since 1977 in Japan are usually interpreted as showing decreasing support among the Japanese population for Official Development Assistance (ODA), and possibly, the Ministry of Foreign Affairs and the Cabinet Office of Japan have justified recent cuts in ODA...

When the preference over intertemporal consumptions is of CIES type and human capital enters the production function in a secific way, we show that the optimum population growth rate is exactly the subjective discount rate in an infinite-horizon Ramsey Model.

This work builds a macro model for livestock farming based on aggregation of initial micro description for rational control of total number of vintage livestock (age cohorts). Solution of an optimal problem on cohort total number of livestock gives the age limit for the operation of animals, the...

This paper examines the empirical relationship between the quality of the Indian judiciary and the economic development of the Indian States and Union Territories. It evaluates this causality by analysing the development of the state-level per capita income and poverty rates. I define the...
