This study seeks to investigate whether firms’ capital structure decisions are congruent with the assumptions underpinning the traditional trade-off theory and the pecking order theory in Ghana. Using a sample of listed firms, the dynamic system generalized method of moments (GMM) technique is applied on a balanced panel data spanning 2008–2016. The findings reveal that the financing decisions of Ghanaian firms adhere to the pecking order theory, given the established relationship between leverage and profitability, firm age, as well as firm size. The study also shows that tax does not matter for corporate leverage, departing from the tax proposition of the traditional trade-off theory. However, the negative effect of growth opportunities and risk on debt corroborates the trade-off theory. Consequently, it is postulated that the trade-off theory and the pecking order theory are not discordant in predicting firms’ capital structure decisions in Ghana.

Purpose – To provide a behavioural perspective on the relationship between transport and climate change.

Methodology/approach – The factors influencing travel behaviour and the elements critical to behaviour formation are reviewed. The importance of behaviour change measures to reduce the impact of transport on climate change, and the application of behaviour change measures to increase the sustainability of transport, are examined.

Findings – There have been a range of travel behaviour measures implemented, such as individualised marketing programmes and travel plans, which have demonstrated some behavioural change impacts, in turn affecting climate change emissions, although they tend to be localised and small-scale.

Social implications – There is a real challenge to encourage individuals within society to exhibit more sustainable travel behaviour.

Originality/value – A range of behavioural issues still need to be resolved in terms of the relationship between transport and climate change, including a need to influence attitudes, to bridge the gaps between attitudes and both behaviour and intention, to make an impact at points of transition for individuals, to use cognitive dissonance as a way of harnessing social norms, and to understand more fully social pressure and group influence.
