The proof of the theorem of existence of the ruptures, namely the proof of maximality, is improved. The theorem may be used in economics and explain the well-known problems such as Allais’ paradox. Illustrated examples of ruptures are presented.

Technologies that are used in different production processes of miscellaneous industries are known as cross-sectional technologies. The economic importance of these technologies normally is measured by economic benchmarks of the producing industry. However, the impact of these tech-nologies for...

The present paper puts forward a new hypothesis about the economic circuit, which is a product of Marx’s “period of production” and Keynes’s determination order between investment and savings. It leads to a new definition of profit which excludes any remaining competition between savings...

Der Input-Output-Analyse wird in der ökonomischen Theorie seit längerer Zeit nur geringe Aufmerksamkeit zuteil. Der vorliegende Aufsatz soll ein Beitrag dazu sein, sie wieder in den Mainstream der Debatte zurückzuholen. Es wird gezeigt, dass klassische Modelle der ökonomischen Theorie –...

In this paper, we propose a usual strategy in order to estimate the impact of a free trade area agreement between EU and Mediterranean Partner Countries (MPC's). In this frame, a dynamized Input-Output model is developed, obtaining the main economic impacts in each MPC country (employment, Value...

The North Cyprus economy has been under economic embargoes for many years, and has been struggling to eradicate the income difference with the south of the island with extremely limited facilities. Successive governments have accordingly developed distinctive responses to cope with these...

This paper estimates the impact of an increase in Brazilian sugar and ethanol demand for exports upon the countries� overall production and employment. The impacts were simulated considering each of the major cane producing areas of the country (Center-South and North-Northeast). An...

The Brazilian meat production in 1999 is estimated at 12.8 million tons, and the main productive chains of this sector are: a) the beef chain (6.7 million tons); b) the poultry chain (5.0 million tons); and the pork chain (1.7 million tons). Brazil is the world second largest beef producer...

By using a heteroscedastic stochastic frontier model, this paper focuses on how students' exogenous characteristics (such as personal demographic information, pre-enrollment educational background and household economic status) affect faculties’ inefficiency. Using individual data on freshmen...

This paper incorporates the Bhaduri-Marglin accumulation function in Goodwin’s growth cycle model. It seems that, a priori, nothing unambiguous can be said about the dynamic behaviour of that extended system, since it depends crucially on two separate factors: (i) the form of the accumulation...
