Earnings management to exceed thresholds in continental and Anglo-Saxon accounting models: The British and French cases
2017
International audience; The purpose of this paper is to compare the extent to which French and British firms manage their earnings in order to avoid losses, decreases in earnings and earnings below the forecasts of analysts.

Britain and France, correspondingly, belong to those different socio-economic environments. Based on a panel data of 1771 French and 2057 British firm-year observations during the period 2002–2012, we show that all firms considered manage earnings to beat zero and last year’s earnings…
