CAPM, Higher Co‐moment and Factor Models of UK Stock Returns

In this paper we examine the variables that explain the cross‐section of UK stock returns. Previous studies have found that the CAPM beta has moderate or even insignificant explanatory power once the Fama French factors are included. However, we control for different realised risk premia in up and down markets by using the same methodology as Pettengill, Sundaram and Mathur (1995). Unlike previous work, we find that beta is highly significant in explaining the cross‐section of UK stock returns and more importantly remains significant even when the Fama French factors are included in the cross‐sectional regressions. We also investigate whether higher co‐moments (co‐skewness and co‐kurtosis) have any explanatory power but find that empirical support is weaker.     

On the Determinants and Dynamics of Trade Credit Use: Empirical Evidence from Business Start‐ups

Abstract:   Business start‐ups provide an excellent opportunity for testing various hypotheses on why firms use trade credit. At the time of start‐up, failure risk and financial constraints are typically large. Also, start‐ups have no established relationships with banks and suppliers. The literature has related all these features to trade credit use. Moreover, as firms grow older, these characteristics become less pronounced, allowing us to test the dynamics of trade credit use. We find that start‐ups use more trade credit when financial constraints are large, when suppliers have a financing advantage over banks in financing high‐risk firms, when entrepreneurs value private benefits of control and when transaction costs are important. Furthermore, the dynamic implications of these theories are supported.     

Earnings Conservatism, Litigation and Contracting: The Case of Cross‐Listed Firms

Abstract:   We compare earnings conservatism of UK companies cross‐listed in the US to that of UK companies without a US‐listing. We expect that conservatism will be more pronounced for cross‐listed firms than for firms with a UK listing only, because the cross‐listed firms face a stricter enforcement regime. Furthermore, cross‐listed firms may use a listing on a US exchange to signal high‐quality reporting to investors. Using a matched‐pairs research design, we find that earnings of UK cross‐listed firms are significantly more conservative than earnings of UK firms without a US listing. Moreover, cross listed firms display particularly high levels of conservatism during the early years of their cross‐listing. This indicates that firms use earnings conservatism to commit to highly demanding reporting requirements and in doing so communicate a perception of investor care.
