The study examined a nonlinear relationship between inflation and growth through financial development using data for Nigeria, Ghana and Cote d'Ivoire for periods between 1970 and 2010. The threshold value of inflation that could ensure positive association in the finance-growth nexus was...

This paper studies the impact of ambiguity in the best shot and weakest link models of public good provision. The models are ?rst analysed theoretically. Then we conduct experiments to study how ambiguity affects behaviour in these games. We test whether subjects? perception of ambiguity differs...

We report an experimental test of the influence of ambiguity on behaviour in a coordination game. We study the behaviour of subjects in the presence of ambiguity and attempt to determine whether they prefer to choose an ambiguity safe option. We fi?nd that this strategy, which is not played in...

The study analysed the effect of institution on resource curse abundance-economic growth nexus using the system generalised method of moments. The empirical results refute the resource curse hypothesis in Africa. In addition, institutions have dampening effect on the nexus. This stems from the...

In the energy-growth nexus, due to structural change that cannot be accounted for in the linear model this study considers the possibility of the nonlinear model. Using dataset for fifteen countries in Africa for the period 1980-2010, we found that linear model has misspecification error, thus,...
