Purpose: This paper aims to investigate how home-based telework (HBT) affects job stress. The authors argue that an intrinsic effect of telework like work extension mediates this relationship. Work extension is reflected in two employee behaviours: working in free time and presentism. Design/methodology/approach: The proposed model has been estimated using the Preacher and Hayes bootstrap method for multiple mediation analysis, with 1,000 repetitions. The data used come from the sixth European Working Conditions Survey. Findings: The analysis indicates that HBT does not pose an inherent risk for job stress but causes a change in the employees' behaviour, increasing working in free time and presenteeism and thus job stress. The mediation model indicates that once these behaviours are controlled, the effect of HBT is to reduce stress. Research limitations/implications: The authors argue that companies should focus on human resource practices to control workers' behaviours that have a detrimental effect on job stress while institutions should regulate HBT. Originality/value: The analysis deepens the unclear relationship between HBT and job stress by introducing employees' behaviours concerning work extension into the equation., The authors wish to thank for grants PID 2020-114460GB-C32 and PID 2020-115018RB-C31 funded by MCIN/AEI/10.13039/501100011033.

This paper analyses the impact of local competition on gasoline and diesel pricing at branded and unbranded independent service stations. Based on our theory-driven discussion we derive a number of hypotheses, which are empirically tested on a sample of service stations in Spain. In Spain, retail prices of motor fuels have been under the spotlight since the dismantling of the state monopoly in the 1990s. The concentration of the retail market and the behavior of the main oil operators are of constant concern to the competition authorities. Our empirical analysis provides evidence for the existence of different competitive dynamics between branded and unbranded stations, and between gasoline and diesel retail pricing. Specifically, the results show that (i) fuel prices at branded (unbranded) service station are positively (negatively) associated with the number of stations operating in the same local market, (ii) prices of both motor fuels at a branded station are higher the larger the share of stations carrying the same brand in its local market, (iii) diesel price at an unbranded station is lower the larger the share of unbranded stations in its local market, and (iv) unbranded service stations undercut the price of diesel more than that of gasoline compared with prices at branded stations., The authors acknowledge financial support from the Spanish Ministry of Science and Innovation, Grant PID2020-114460GB-C32 funded by MCIN/AEI/10.13039/501100011033 and Grant 2021/00064/001.

Introduction: Despite the significant economic impact of occupational injuries on companies and society, studies focused on analyzing the determinants of workdays lost due to sick leave remain scarce and incomplete. This paper contributes to this issue by (a) analyzing the drivers of sick leave duration, distinguishing factors that explain the health recovery time from those that could lead workers to a voluntary extension of the absence period, and (b) formulating and empirically testing the effect of gender, citizenship, temporary work, job tenure, amount of disability benefit, and size of the injured worker's firm on the number of days the employee is off work after the injury. Method: Hypotheses are tested on a comprehensive dataset that includes all nonfatal occupational injuries causing sick leave that occurred in the manufacturing sector in Spain during 2015¿2019, with more than 400,000 injuries. We conduct ordinary least squares and count data regression models in which the number of days off work is regressed on employees and work characteristics while accounting for a set of variables to control the injury's nature and severity. Results: The results show that after considering the intrinsic characteristics of the injury and the severity of the worker's injuries, women, native workers, workers with more seniority, workers with higher salaries, and those working in larger companies have longer periods of sick leave. The results suggest that moral hazard considerations significantly impact the time to return to work after an occupational injury. Practical applications: Based on the findings, several insights for company managers and public decision-makers are discussed. Specifically, interventions aimed at improving the organization of work and the working conditions of workers in manufacturing industries are highlighted, as well as the need to improve control and supervision mechanisms during the recovery process of injured workers., The authors acknowledge financial support from the Spanish Ministry of Science and Innovation, Grant PID2020-114460GB-C32 funded by MCIN/AEI/ 10.13039/501100011033.
