There is much disagreement about both the facts and the explanations of income inequality. Even if we confine attention to OECD countries, we find people arguing that there has been a great U-turn, with inequality rising sharply after its post war fall, and others who believe that the speed of...

We develop a $C_{p}$ statistic for the selection of regression models with stationary and nonstationary ARIMA error term. We derive the asymptotic theory of the maximum likelihood estimators and show they are consistent and asymptotically Gaussian. We also prove that the distribution of the sum...

We use the forward search to provide robust Mahalanobis distances to detect the presence of outliers in a sample of multivariate normal data. Theoretical results on order statistics and on estimation in truncated samples provide the distribution of our test statistic. We also introduce several...

We develop a Cp statistic for the selection of regression models with stationary and nonstationary ARIMA error term. We derive the asymptotic theory of the maximum likelihood estimators and show they are consistent and asymptotically Gaussian. We also prove that the distribution of the sum of...

This study contributes to the growing body of research examining the governance processes undertaken by Boards of public companies. Specifically, we investigate the Board's role in developing, executing and monitoring strategy and the nature and extent of strategic performance information...
