The Impacts of the Basel II Accord on the Concentration of the Entrepreneurial and Banking System

From the econometric analysis model, even though based on the US economy, one deduces the existence of an important correlation between the intervened changes in the role of banks’ prudential capital and in merger and acquisition dealings: the latter have increased, at least in number, after the reviewing of prudential capital requirements in favour of better structured banking organizations. The analysis of the Italian entrepreneurial and banking system shows a country characterised by small-scale enterprises with meagre growth capability (even though the Accord, paradoxically, is meant to facilitate the granting of loans to the development of small-scale enterprises), but also by the great expanding potential of banking enterprises that, contrarily to the other productive entities, can count of high re-investible margins and, consequently, of wide capabilities of investing in private equity.      

The Correlates of Farm Concentration in American Agriculture

Abstract In recent years, the most pronounced change in the structure of American agriculture has been the increasing concentration of farm production. A human ecological perspective was used to generate hypotheses about the factors related to variations in farm concentration in U.S. counties. Analysis using the 1978 and 1987 Censuses of Agriculture revealed that concentration is greatest in counties with higher levels of agricultural intensity, greater use of mechanization, and greater use of farm labor.
