Day‐of‐the‐Week Effect in High Moments

Evidence from equity markets worldwide indicates that the Day‐of‐the‐Week anomaly appears to fade from the first moment of the distribution of daily returns. We report highly significant pair‐wise weekend effects in high moments when comparing the first and last trading days of the week. The second moment alone appears to distinguish the return distribution of the first trading day from all others. A probable explanation of the phenomena appears to be information dissemination: corporate announcements released after closing of the last trading day of the week spill‐over to the opening of the first trading day, increasing its variability and carrying the closing sign.

Decision making in the multiproduct firm: Adaptability and firm organization

This study presents an explicit model of the choice process by which decision makers within a multiproduct firm would optimally allocate their firm-specific inputs. The first-order conditions of the model indicate the kind of information required for efficient transfer of these inputs. Transfer within the firm can be more efficiently accomplished than contracting over markets. Consequently, one may demonstrate the superior efficiency of the multiproduct firm over a comparable group of single-product firms independent of any production externalities. Further, this superior efficiency results only if the central administration of the firm controls the exchange of these inputs.
