This paper aims to assess all the Brazilian electric power transmission line auctions occurred between 1999 and 2017.

A copula-based Roy/endogenous switching regression model is used. The suitability of this model is twofold: it takes into account the selection bias problem involving auctions data and it allows more flexibility in modeling the joint distribution between the unobserved components of the selection and outcome equations; thus, normal distribution assumptions are not needed.

The main results suggest that stated-owned companies have the highest probability of winning an auction, and there is a non-competitive behavior among the players in the auction. The results also suggest some departure from joint normality in the data.

The copula-based sample selection approach used in this paper is consistent under non-normality and allows one to address different types of nonlinearities in the data such as asymmetry and heavy tails.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

The purpose of this paper is to integrate Brazilian agro-industrial co-operatives’ horizontal, lateral and vertical integration diversification and expansion strategies, such as operation area and membership, with financial models. Several studies have tried to assess the importance of diversification on the financial outcomes in agricultural co-operatives with limited success.

The three main concepts were combined in a working model. A survey was developed to gather data on financial, diversification and expansion strategies from 67 co-operatives (44 per cent return rate). Data were processed using a partial least squares structural equation model.

The findings suggest that expansion is directly responsible for both the financial output and diversification strategy; however, no hard evidence supports the view that the diversification of production in some agro-industrial co-operatives leads to positive financial results.

Only larger Brazilian co-operatives (>$50m in annual revenues) were considered. Co-operatives facing other scenarios or smaller co-operatives could have different outcomes.

Besides diversifying their co-operatives for financial reasons, managers should also consider risk aversion and adapting to new farmers’ portfolios as probable reasons.

Extant literature asserts that diversification leads to financial growth; as the co-operatives studied show no such causal relationship, it follows that they diversify their portfolios for other purposes.
