  The particular day of the week when an event occurs seems to have unexpected
consequences. For example, the day of the week when a paper is submitted to a
peer reviewed journal correlates with whether that paper is accepted. Using an
econometric analysis (a mix of log-log and semi-log based on undated and panel
structured data) we find that more papers are submitted to certain peer review
journals on particular weekdays than others, with fewer papers being submitted
on weekends. Seasonal effects, geographical information as well as potential
changes over time are examined. This finding rests on a large (178 000) and
reliable sample; the journals polled are broadly recognized (Nature, Cell, PLOS
ONE and Physica A). Day of the week effect in the submission of accepted papers
should be of interest to many researchers, editors and publishers, and perhaps
also to managers and psychologists.
