Proactive environmental strategy and firm performance at the bottom of the pyramid

This paper utilizes insights from the natural resource-based view to examine the conditions under which proactive environmental strategy (PES) drive firm performance. Using data collected from 266 small- and medium-sized enterprises operating in Ghana, the results suggest that the impact of PES on firm performance is more pronounced in firms that do not purse bottom of the pyramid orientation but not significant for firms pursuing the bottom of the pyramid orientation. Besides, the findings show that the influence of PES on firm performance is amplified for firms adopting imitation orientation but not significant for nonimitation-oriented firms. Implications and directions for future research are discussed.

The effect of entry on R&D networks

We investigate the effect of potential entry on the formation and stability of R&D networks considering farsighted firms. The presence of a potential entrant often alters the incentives of incumbents to collaborate. Incumbent firms may form an otherwise undesirable collaboration to deter entry of a new firm. Moreover, an incumbent may refrain from establishing an otherwise desirable collaboration, expecting to form a more profitable link with the entrant. Finally, potential entry may lead an inefficient incumbent to exit the market. Welfare analysis shows market and social incentives to be often misaligned. We propose a subsidy scheme that encourages welfare‐improving entry.     

The Politics of Shareholder Activism in Nigeria

Shareholder activism has become a force for good in the extant corporate governance literature. In this article, we present a case study of Nigeria to show how shareholder activism, as a corporate governance mechanism, can constitute a space for unhealthy politics and turbulent politicking, which is a reflection of the country’s brand of politics. As a result, we point out some translational challenges, and suggest more caution, in the diffusion of corporate governance practices across different institutional environments. We contribute to the literature on corporate governance in Africa, whilst creating an understanding of the political embeddedness of shareholder activism in different institutional contexts—i.e. a step closer to a political theorising of shareholder activism.     

Exchange Rate Flexibility and the Effect of Remittances on Economic Growth

This paper studies the question of whether exchange rate policy affects the impact of remittances on economic growth in recipient countries. The findings indicate that more flexible exchange rate regimes are associated with a greater increase in economic growth following an increase in remittances, but also that the impact of remittances on growth is positive under a fixed regime. The results further show that the effect of remittances under a fixed exchange rate regime is positive in less financially developed countries as well, but do not provide conclusive evidence that this effect varies inversely with exchange rate flexibility in such economies as theorized; the results being sensitive to the choice of financial development indicator.     

ACHIEVING SOCIAL OBJECTIVES THROUGH PRIVATE TRANSFERS: A Review

Private interhousehold cash transfers are an important sourceof income in many developing countries. Among the countrieswhose experience is reviewed in the article, the proportionof all households receiving private transfers ranges from afifth to a half. The amounts received are large, particularlywhen compared with the incomes of the poorest households. Understanding more about these transfers is important for designingpolicy because, among other things, these remittances providesocial and economic benefits similar to those of public programs,such as unemployment insurance, pension support, educationalcredit, and health assistance. As such, private transfers maysupplement or overlap with public transfers, and, if privatedonors give less as public transfers increase, the effect ofpublic programs on beneficiaries would be less than originallyintended. Or the transfers may alter the distributional effectsof public programs: for again, if private donors give less aspublic transfers increase, they share in some of the benefitsof public programs.      

Nonlinearity and the Unit Root Hypothesis for African Per Capita Real GDP

Once described as an epic center of growth tragedy, African nations have lately achieved relatively rapid growth rates, which have raised hopes that the continent is finally on the path to economic convergence with other emerging economies. However, there is a need to establish whether stabilization policies for the purpose of enhancing the GDP are effective in African countries. One of the means of examining the effectiveness of these policies is through the investigation of the unit root properties of per capita GDP in the continent. This study aims to add to the existing papers on GDP in African countries by investigating the non-stationarity of per capita GDP in 52 African countries, while using a newly proposed nonlinear unit root test. The results suggest that per capita GDP follows the non-stationarity process in half of the entire sample.     

Corporate Social Responsibility in Challenging and Non-enabling Institutional Contexts: Do Institutional Voids matter?

The extant literature on comparative Corporate Social Responsibility (CSR) often assumes functioning and enabling institutional arrangements, such as strong government, market and civil society, as a necessary condition for responsible business practices. Setting aside this dominant assumption and drawing insights from a case study of Fidelity Bank, Nigeria, we explore why and how firms still pursue and enact responsible business practices in what could be described as challenging and non-enabling institutional contexts for CSR. Our findings suggest that responsible business practices in such contexts are often anchored on some CSR adaptive mechanisms. These mechanisms uniquely complement themselves and inform CSR strategies. The CSR adaptive mechanisms and strategies, in combination and in complementarity, then act as an institutional buffer (i.e. ‘institutional immunity’), which enables firms to successfully engage in responsible practices irrespective of their weak institutional settings. We leverage this understanding to contribute to CSR in developing economies, often characterised by challenging and non-enabling institutional contexts. The research, policy and practice implications are also discussed.     

The role of volume in order book dynamics: a multivariate Hawkes process analysis

We show that multivariate Hawkes processes coupled with the nonparametric estimation procedure first proposed in Bacry and Muzy [IEEE Trans. Inform. Theory, 2016, 62, 2184–2202] can be successfully used to study complex interactions between the time of arrival of orders and their size observed in a limit order book market. We apply this methodology to high-frequency order book data of futures traded at EUREX. Specifically, we demonstrate how this approach is amenable not only to analyse interplay between different order types (market orders, limit orders, cancellations) but also to include other relevant quantities, such as the order size, into the analysis, showing also that simple models assuming the independence between volume and time are not suitable to describe the data.     

Interpretable Machine Learning Using Partial Linear Models*

Despite their high predictive performance, random forest and gradient boosting are often considered as black boxes which has raised concerns from practitioners and regulators. As an alternative, we suggest using partial linear models that are inherently interpretable. Specifically, we propose to combine parametric and non-parametric functions to accurately capture linearities and non-linearities prevailing between dependent and explanatory variables, and a variable selection procedure to control for overfitting issues. Estimation relies on a two-step procedure building upon the double residual method. We illustrate the predictive performance and interpretability of our approach on a regression problem.
