This paper examines the contentious relationship between investment and cash flow using the 2008–2009 credit supply shock as a form of the quasi-natural experiment.
Panel threshold models with unknown sample separation are estimated for a sample of publicly listed firms from nine African countries over the period 2003–2012. Using this approach reduces subjective or ex ante sample-splitting bias that is not accounted for in the extant literature.
The findings of the study indicate that investment–cash flow sensitivity is decreasing even during the global financial crisis (GFC) and for firms more likely to be financially constrained. The authors conclude that the usefulness of investment–cash flow sensitivity as a proxy for financial constraints is diminishing over time, even after directly addressing biases from ex ante subjective sample splitting and various forms of endogeneity.
The authors provide new empirical evidence from sharper tests of financial constraints for understudied African firms and highlight the need to relook at the usefulness of investment–cash flow sensitivity as a proxy of financial constraints.
