Despite the consensus on the importance of systemic analysis in agriculture, there seems to be little agreement in the economic literature regarding the design of agribusiness. In this work, new perspectives are presented as the identification and measurement method agribusiness. Based on the...

The Input-Output model has made extensive use of graph and network theory, methods and conclusions, in order to carry out structural analysis; such extensions have yielded powerful insights on the relationships existing between industries in an economic system. It is customary in the field to...

Brazil has about 30% of GDP from agribusiness sectors. This shows the importance of agribusiness in the country, which is also one of the largest agricultural producers in the world. Considering the linkage effects of shocks in some non-agricultural and agricultural sectors selected, this study...

This paper reviews the available methods used to convert Supply and Use Tables of actual economic systems to Symmetric Input-Output Tables. It is argued that all conversion methods rest on the unrealistic assumption that single production, and not joint production, characterizes the economic...

Bródy’s conjecture is submitted to an empirical test using input-output flow data of varying size for the US economy for the benchmark years 1997 and 2002, as well as for the period 1998-2010. The results suggest that the ratio of the modulus of the subdominant eigenvalue to the dominant one...

A typical finding in many empirical studies is that the production price-profit rate relationship is, by and large, monotonic. This paper derives, in terms of the usual single-product model, the spectral conditions that make possible the appearance of such monotonicity. Furthermore, using data...

Recent exchanges in the literature on the identification and role of key sectors in national and regional economies have highlighted the difficulties of consensus regarding terminology, appropriate measurement as well as economic interpretation. In this paper, some new perspectives are advanced...

Since the initial input-output (i-o) models conceived by Leontief in the 1930’s, the inputoutput theory has gone through a lot of development at the theoretical as well as applied point of view. However, despite all the progress, there are two points that need further consideration into the...

Despite the advances in recent years in areas as education and combat to the poverty, Brazil continues to have one of the worst income distributions in the world. Nowadays, in a list with 126 countries and territories, Brazil has the 10th worse income distribution. As much as income...
