Corporate Finance in Africa: The Interactive Impact of Firm Nationality and Characteristics

Using a balance panel data of 351 publicly quoted firms in eleven major African stock exchanges, I investigated the impact of the differences in the internal structures of domestic and foreign firms on corporate financial decisions in Africa. I also analyzed the sensitivity of the impact of the internal firm characteristic on changes in the level of exogenous factors such as marginal tax structure and financial system development. The arising results showed that among the selected key internal characteristics of firms, only the impact of profitability and tangibility on financial structure was significantly sensitive to the proportion of domestic/foreign shareholding and that, consistent with capital structure theories, corporate financing decisions in Africa were significantly sensitive to marginal tax policies and the degree of financial system development prevailing in a country. The results suggest that by investing in assets that are acceptable to lenders and investors as collaterals and maintaining reasonable stability in their cash flow positions, domestic firms can in practice enhance their access to strategic investment capital.     

The effects of uncertainty on investment and the expected long-run capital stock

This paper examines the effects of output price uncertainty on the optimal investment behavior of a risk-neutral competitive firm with a constant returns to scale production function. In the presence of convex costs of adjustment, investment is an increasing function of q, the shadow price of capital. Given the current price of output, we find that increased uncertainty will raise the current rate of investment. Increased uncertainty will also increase the expected long-run capital stock if the price of output is serially uncorrelated. However, if the price of output is serially correlated, then the direction of the effect of increased uncertainty on the expected long-run capital stock depends on the curvature of the marginal adjustment cost function. In this case, we obtain results which are directly opposite of the results in the literature and we locate the flaw in the existing analysis.     

Leveraging competitiveness upon national cultural traits: the management of people in Brazilian companies

This paper aims to discuss the leveraging of competitiveness upon cultural traits. Since the globalization process has raised a series of challenges for companies around the world, companies have sought to respond mainly through the adoption of management practices proved to be successful elsewhere. However, due to the anchoring of many management practices, especially those of human resources, in the socio-cultural context of a country, the import and/or transfer of management practices between different contexts risk resulting in changes which may be only superficial. There are, however, some exceptions. Some managers have chosen to build their companies' competitiveness through management practices firmly anchored on the cultural traits of their countries, instead of looking for practices from successful companies. This process is obviously not simple because it requires from company leaders first the capacity to re-signify the cultural trait in a different manner, i.e. to perceive it as a source of competitiveness for the company and, second, the competence to build a management practice upon this cultural trait so that it will leverage the competitiveness of the company. In order to illustrate how typical cultural traits from a country may leverage the competitiveness of a company, we present the case of Natura, a Brazilian cosmetics manufacturer, which has constructed much of its competitiveness through the adoption of management practices anchored in some typical Brazilian cultural traits. The analysis of the case demonstrates that this process of developing competitive management practices is feasible, but it must be based upon a solid system of values that the team leader practises or wants practised. Otherwise, it is unlikely that the management practices will stand or that people will be committed to them.     

INSTITUTIONS,ECONOMICS AND THE DEVELOPMENT QUEST

Institutions crucial for the analysis of how agents deal with uncertainty have been gaining increasing relevance on the economic research agenda. In this paper, we analyze the institutional literature aiming to explain why this perspective obtains better results than others in development economics. In particular, we stress the relevance of New Institutional Economics as an adequate framework for a broad understanding of development issues.     

Finding Bayesian Optimal Designs for Nonlinear Models: A Semidefinite Programming‐Based Approach

This paper uses semidefinite programming (SDP) to construct Bayesian optimal design for nonlinear regression models. The setup here extends the formulation of the optimal designs problem as an SDP problem from linear to nonlinear models. Gaussian quadrature formulas (GQF) are used to compute the expectation in the Bayesian design criterion, such as D‐, A‐ or E‐optimality. As an illustrative example, we demonstrate the approach using the power‐logistic model and compare results in the literature. Additionally, we investigate how the optimal design is impacted by different discretising schemes for the design space, different amounts of uncertainty in the parameter values, different choices of GQF and different prior distributions for the vector of model parameters, including normal priors with and without correlated components. Further applications to find Bayesian D‐optimal designs with two regressors for a logistic model and a two‐variable generalised linear model with a gamma distributed response are discussed, and some limitations of our approach are noted.     

Corporate social responsibility perception in business students as future managers: a multifactorial analysis

This paper examines undergraduate business students' perception of corporate social responsibility (CSR) in cases in which they have not attended any specific course either dealing with CSR or providing training in ethics. A survey was conducted of 535 Spanish business students as future managers. The results show that the stakeholders' perspective deserves a huge attention for those students considering what the keys of business success are. Significant differences in perception were nevertheless identified when a multifactorial analysis was undertaken. Female students are more concerned about CSR issues. The maximization of value for shareholders is less valued by second‐ and third‐year students than by first‐year ones. The findings point to a number of important orientations for the future development of university curriculum.     

Does having women managers lead to increased gender equality practices in corporate social responsibility?

There is increasing interest in determining what impact having women in management positions may have on corporate social responsibility (CSR) initiatives. Various authors suggest that gender equality practices should be factored into the broader framework of CSR. This paper examines how the presence of women on corporate boards, in top and middle management and as heads of CSR departments, influences gender equality practices in the field of CSR. Using information collected from companies that have signed up to Women's Empowerment Principles in Spain, we show that the presence of women in the aforesaid posts has a positive impact on CSR activities with gender equality objectives. We thus supplement the justice, business and moral arguments with further arguments in support of the incorporation of women into not only corporate boards but all management positions. Finally, we provide a view of how gender equality can be included in the broader framework of CSR.     

Dynamic effects of permanent and temporary tax policies in a q model of investment

This paper incorporates the tax policy analysis of Hall and Jorgenson into a dynamic optimizing model with adjustment costs to develop a q model of investment. This framework is particularly useful for analyzing the dynamic effects on investment of permanent and temporary changes in tax policy. It is shown that, contrary to the conventional intertemporal substitution argument, a temporary investment tax credit need not be nore expansionary than a permanent investment tax credit. The role of depreciation allowances in determining the dynamic response of investment to temporary changes in the tax rate is also investigated.     

Input-output pricing in a Keynesian model as applied to Portugal

This paper develops a Keynesian model of the Portuguese economy in which the prices of the sectors of final demand are derived from input-output relationships. This model is used for short-run simulation analysis of the Portuguese economy through 1977. It is seen that Portugal cannot simply rely on world demand for its exports to improve its balance of payments and to generate an export-led recovery. Simulation of a policy package which includes a devaluation and fiscal restraint indicates that this policy will improve the external current account and raise domestic savings.
