Proposal of a coefficient to evaluate the management of the internal control

The objective of this article is to propose a management index for the Internal Control of care entities. This was conceived following the multicriteria modeling guidelines in conjunction with the detection of weaknesses through the Petri networks. For this purpose, the order of importance and compliance of the internal control components were determined, and the lack of reliability of the critical processes in the entity subject to the practical implementation was identified. Derived from its humanitarian mission – lending quality health care to the population – it is necessary to decrease the emergence of events that could infringe upon the physical and psychological integrity of the patients in hospitals. One of the strategies to consider to overcome this challenge is the adequate implementation of the Internal Control System, which guarantees the sustainability of the insurers through the increase in the efficiency of the care of the people, feasible only within a care model that quantifies the control over the population already identified and cared for.     

Location of cargo terminals in metropolitan areas of developing countries: the Brazilian case

This article presents a procedure for establishing and ranking the areas that are candidates for building truck cargo terminals, based on the analytic hierarchy process (AHP) and considering location factors, with focus on accessibility considerations, expressed by indicators derived from graph theory. Accessibility is thus defined objectively for each area, contemplating its needs regarding production or consumption of cargo or promotion of intermodal transport of products. The proposed approach determines the most suitable area for locating the terminal according to the perception of each actor participating in the process as well as the set of actors, seeking to conjugate conflicting interests and facilitate convergence and the establishment of negotiated solutions. With this, it provides a more transparent and participative decision-making process and supplies basic elements for government bodies to formulate their socioeconomic development policies. The application of this procedure in the greater Rio de Janeiro metropolitan region demonstrated its feasibility in developing countries and in contexts with restricted data, funding and planning.     

The impact of racial and gender diversity in management on financial performance: how participative strategy making features can unleash a diversity advantage

How does racial and gender diversity in the management ranks affect the bottom line? Our findings indicate that participative strategy making (PSM) positively moderates the relationship between both racial and gender diversity in management and firm performance measured as return on assets. Specifically, PSM strengthens the positive relationship that exists between racial diversity in management and firm performance. Although no main effect is observed for gender diversity in management, our results reveal that gender diversity in management is positively related to performance when PSM is high. However, we find that gender diversity in management is negatively related to performance when PSM is low, while gender homogeneous management experience superior performance. We offer implications for diversity research to embrace and consider the role of PSM and ‘inclusiveness’.     

Exploring the performance effects of visible attribute diversity: the moderating role of span of control and organizational life cycle

Research on how cultural diversity – especially visible attributes such as race and gender – impacts organizational performance remains practically nonexistent. We examine the effect of racial diversity and gender diversity on firm performance utilizing a contingency framework. Empirical findings from a field study support the hypothesized contingent effects of an organization's structure, specifically managerial span of control, on both racial and gender diversity's pre-assumed benefits. In addition, the study highlights the role of life-cycle stage when modelling the diversity–performance relationship. Future research directions and managerial implications are discussed.     

Linking top management team age heterogeneity to firm performance: juxtaposing two mid-range theories

Previous research on top management team heterogeneity and firm performance has focused almost exclusively on the non-visible attributes (e.g. functional background, tenure) of cultural diversity as opposed to the visible attributes (e.g. age, race and gender). The few studies there are show inconsistent results. For example, most field work - consistent with social identity theory notions - shows that cultural diversity, in isolation has negative organizational consequences. Only a few laboratory studies, however - consistent with information and decision-making theories - show that diversity in groups relates to favourable organizational outcomes. As social identity theory suggests, we find that top management team (TMT) age heterogeneity, in isolation, relates negatively to return on assets. On sales growth (i.e. organizational growth), the relationship is positive, lending support for information and decision-making theories. However, we find a curvilinear relationship between TMT age heterogeneity and sales growth, supporting both the mid-range theories. More specifically, TMT age heterogeneity is positively related to sales growth at low and medium levels and negatively related to sales growth at high levels. In addition, results reveal that context moderates linear and non-linear relationships. The results provide evidence of the importance of cultural diversity in TMTs for competitive advantage but also suggest the complexities of increasing it to observe these benefits.     

Too much of a good thing: Endogenous business cycles generated by bounded technological progress

Following Jones and Williams [Jones, C.I., Williams, J., 2000. Too much of a good thing? The economics of investment in R&D. Journal of Economic Growth vol. 5 (no. 1), 65–85], we assume that R&D is simultaneously subject to positive and to negative external effects (e.g., the non-rival nature of technology conflicts with congestion externalities). This observation allows to conceive an economy where two R&D sectors evolve without departing significantly from each other in terms of their productive results (society tends to penalize imbalances in technical progress, making negative external effects to appear associated to a sector when this outstands relatively to the other sector; the second sector, in turn, will be subject to positive externalities that reflect a catching up effect). The proposed framework, when associated to a growth setup, is able to replicate the existence of endogenous fluctuations and, therefore, it intends to be a contribution to the literature on endogenous business cycles.     

A two-dimensional non-equilibrium dynamic model

This paper develops a non-equilibrium dynamic model (NEDyM) with Keynesian features (it allows for a disequilibrium between output and demand and it considers a constant marginal propensity to consume), but where production is undertaken under plain neoclassical conditions (a constant returns to scale production function, with the stocks of capital and labor fully employed, is assumed). The model involves only two endogenous/prognostic variables: the stock of physical capital per unit of labor and a measure of market disequilibrium (MMD). The two-dimensional system allows for a careful analysis of local and global dynamics. Points of bifurcation and long-term cyclical motion are identified. The main conclusion is that the disequilibrium hypothesis leads to persistent fluctuations generated by intrinsic deterministic factors. These fluctuations may reflect some of the features frequently encountered in observed business cycles, once the model is conveniently adapted to this purpose.     

Wheat policy and economy-wide reform in Brazil

In recent years, the wheat sector in Brazil has moved from governmental protection and public intervention to a free market and privatization. In this study, those changes are analyzed through measures of governmental intervention on nominal rates of protection and on welfare of producers and consumers. Elasticities of demand and supply of wheat are estimated, and the effects of changes in policies are analyzed under official and shadow exchange rates. Welfare measures indicate that almost US$ 8 billion were spent from 1970 until 1989 with policies to subsidize producers and consumers. The policy-induced stimulus to consumer demand exceeded the stimulus to domestic production, and self sufficiency in wheat declined. The reduction in wheat subsidies since 1989 was more than an isolated sector-specific policy. It was part of macroeconomic antiinflation policy, and it coincided with other economy-wide changes such as real appreciation and a decline in international commodity prices.     

Antecedents and consequences of psychological contracts: Does organizational culture really matter?

Exploring the role of psychological contracts, this study proposes that different organizational cultures are associated with relational psychological contracts compared to transactional contracts while both types of contracts serve as mediators. While clan cultures positively impact relational contracts and are negatively associated with transactional contracts, hierarchical cultures have the reverse effect. In addition, psychological contract types mediate the two culture types' relationship to both organizational commitment and employee yearly earnings. In sum, clan cultures relate to more positive organizational outcomes than hierarchical cultures, a finding which as implications for future research and practice.
