    Abstract To reduce fossil energy consumption and mitigate carbon emission in an economy, it is important to examine the energy use of the physical capital factor input, taking the Nigerian production process as an example, given that Nigeria is the largest economy in Africa by Gross Domestic Product (GDP), Purchasing Power Parity (PPP), Population, etc. On the other hand, while existing literature assumes energy-use as an independent factor input, this article argues that energy-use is a dependent factor input in a production function relationship. Therefore, this paper seeks to model the production processes differently, by considering energy-use as a dependent factor input of production. Hence, the Energy Efficient Constant Elasticity of Substitution (EE-CES) production function is proposed to model the aggregate production process in Nigeria while taking energy-use as a capital-dependent input factor. The Indirect Least Square (ILS) results show a 19% actual capital energy-efficient level in Nigeria. The marginal productivity of energy-efficient capital exceeds that of labour and energy-inefficient capital. The Nigerian factor inputs exhibit increasing returns to scale with a homogenous of degree three-second. On average, the Nigerian production process is more labour intensive than capital intensive. Therefore, conscious efforts are required to simultaneously make the Nigerian production process more capital-intensive and improve the energy-efficiency of the capital input. The implication of this study is not peculiar to Nigeria but includes other developing economies, mostly African economies, with a more labour-intensive production system.

    Abstract Carbon emission from Africa’s tropical land in 2016 is 6 billion tonnes. Thus, Africa emits a substantial amount of carbon. It is therefore important to study the emission of carbon in Africa, taking Nigeria, the largest economy in Africa, as a case study. Currently, Nigeria experiences rapid increases in the level of carbon emissions. Production activities play key roles in understanding the level of carbon emission in an economy. Therefore, this article analyzes the drivers of carbon emission, from production activities, at different quantile levels. Hence, the proposed Augmented Kaya Identity (AKI) model incorporate the role of the input-output relationship in carbon emission from production activities. Generally, the results confirm that the choice of input-output relationship is a key determinant of carbon emission. The Nigerian carbon emission decreases in quantile and while some factors’ elasticities are constant, others are quantile-drive. The proposed model also outperforms the basic Kaya Identity aside from estimating the input-output relationship impact on carbon emission at all quantile levels. These findings are externally valid for other African countries. Among others, the policy implication of this article includes providing the evidence and justification for Africa to move to cleaner energy sources in production activities to reduce emissions. Also, it provides the tool & background evidence of the key drivers of carbon emission and their elasticities for policy formulation and implementation in African economies.

    Abstract Strategic decision-making for sequential move games requires rationality and continuity of rationality to guarantee maximum payoffs at all nodes/stages/levels. Rationality and continuity of rationality in a player's behaviour are not often observed and/or maintained thus, leading to less optimal outcomes. More so, the belief in an opponent's rationality, on the other hand, co-determines the level of effort a player employs while making strategic decisions. Given irrationality and discontinuity of rationality in a sequential move game with mover advantages, there are strategic steps (algorithms) to convert and/or maintain the mover advantages of an irrational player. In this paper, the conversion strategy algorithms, as well as the optimal strategy algorithms, are developed using the Beta Limit Sum (BLS) strategy model and the game of strokes. The simulation exercises confirm that the BLS strategy model is an optimal solution for the finite sequential game of strokes. One of the key applications of these strategies is that of resource economics like environmental resources (clean water, air & land). These are public goods, as such, the optimal strategy entails that the community cooperates (as one entity) and takes the same actions or strategy to maintain a healthy and clean state of the communal environmental resources.
