Using the industry as an approximation of the external environment of companies, Dess and Beard proposed the construct organizational task environment (OTE). If the precision of the definition of industry is desirable, it involves a multiplicity of elements that restrict the ability of generalization. This paper aims to contribute by identifying clusters of industries with similar environmental profiles. As the discriminant validity of the OTE construct was tested only by Harris in US manufacturing industry, not supporting it, this study also seeks to contribute by assessing the OTE construct validity for the Brazilian manufacturing industry.

Authors collected data from all manufacturing sectors in Brazil, between 1996 and 2003; they used confirmatory factor analysis with the multi-trait multi-method matrix approach to assess the construct validity and ran environmental dimensions' factorial scores through the cluster analysis to find out natural groupings of industries.

The results support the convergent and discriminant validity of the construct OTE, suggesting that further replication should be conducted in the US economy and in different economic contexts.

The study identified four groups of industries with similar environmental conditions, increasing possibilities of generalization of researches. The limitations stem from measurement in an extended period of time and not measuring changes in the environment.

To expand the analytical capabilities of managers for decision making on the sharing of skills between businesses in different industries.

The main contributions of this work are to further discussions on the validity of the OTE construct and to identify industrial clusters of homogeneous environments.

The purpose of this paper is to examine the development cycle of Brazilian banking sector during the lengthy period between 1889 and 2009, also identifying an equilibrium number of financial institutions based on the carrying capacity of the environment.

The number of institutions in equilibrium is calculated based on the population density dependence model adopted under the organizational ecology theory. Quantitative data of founding and failure and qualitative data (interviews with the directors, officers and chief executive officers (CEOs) of selected companies) were used.

In all three bank segments (commercial, investment and multiple), the total number of banks in operation on December 31, 2009 was below the carrying capacity. However, in the multiple bank segment, the gap between the actual and potential figures is slightly smaller. As indicated by the respondents, there is almost no room for newcomers in the major bank segments. In counterpart, there is still space for new arrivals in the mid-market bank sector.

The findings presented here may change, as carrying capacity is determined by political, legal and economic factors, including the availability of resources in niches and constraints imposed through laws, rules and other regulatory aspects. However, raising the life cycle of the entire population offers opportunities for future research on individual organizational trajectories, using new theoretical and methodological perspectives, such as dynamic capabilities and process theory.

The main contribution of this paper lies in indicating the growth potential for banking institution populations in Brazil, and may be used not only by potential newcomers eager to enter the sector, but also as a tool for assessing anti-trust policies.

The development cycle of Brazilian financial institution populations is unknown, and carrying capacity is a construct less explored by academic literature, particularly in Brazil. This is a unique study since a demography of an entire banking population in a developing country does not exist, besides there is not such a financial institution like the multiple bank in Brazil.
