This study aims to investigate the quality management of public transportation services in the Tunisian context during the COVID-19 outbreak. The empirical study was based on the conjoint analysis approach. The sample collected is composed of 250 individuals who often use the train as a means of transport and the pairwise comparison method is adopted for conjoint analysis.
This study assesses quality management of customer service and takes into account four aspects of service quality such as comfort, way of reservation (possibility of online booking), speed, and safety. The findings revealed that the optimal combination of service offered by the Tunisian national railway company is characterized by the terms “first class”, “online booking”, “express”, and “safety”. It is favored by Tunisian customers during the COVID-19 outbreak.
Additionally, the results show that the maximum utility corresponds to the “safety train” modality followed by “second class”, “online booking”, and finally “stopover”. Moreover, the use of new information and communication technologies (NICT) has importance for train users during the COVID-19 outbreak. Indeed, Tunisians are looking for safety and measures to reduce crowding in a train, to minimize the risk of contagion of COVID-19 outbreak.

Earnings management (EM, hereafter), which affects the quality of corporate financial information, continues to receive increased attention from practitioners and legislators. The paper deals with this topic and attempts to investigate the EM practices around the tax rate cut following the Tunisian tax reform of 2021. Evidence of EM is examined by focusing on both accounting and real EM. From a sample of 61 Tunisian public offering companies, observed from July 1, 2015 to June 30, 2021, the results estimated from the system GMM model argue that this tax rate reduction constitutes a real incentive to shift income from the period of higher tax rate (2020) towards the period of lower tax rate (2021) achieving significant savings for corporations. Furthermore, the results show that Tunisian firms have both accounting and real EM downward in the second half of 2020, and that the former is sharper. For the first half of 2021, the results show a joint use of accruals management and real management upwards, and that the latter is broader. These findings may be useful to tax policy-makers in the application of tax rules put in place to counter aggressive tax evasion. In addition, external auditors and tax auditors should consider the period around the change in the corporation tax rate to be more suspect.
