Smoking bans are sweeping Europe. New research suggests that these bans reduce smoking amongst those directly affected and their families and peers, creating what could be called a “public health multiplier”.

The importance of environment and how workers affect the productivity of co-workers through learning valuable skills and work habits is often stressed, but whether employees sometimes learn unethical practices from their peers in order to boost productivity is less well documented. The authors of CEPR DP6550 find that once a worker adopts questionable methods - which seem to be effective, competitive pressures may lead others to follow in order to get ahead, or perhaps just to stay even with other workers who are adopting similar techniques.

How does the effort shown by one worker affect the efforts of fellow workers within the same firm? While frequently proposed behavioural explanations would lead us to expect that one worker trying harder would encourage others to also try harder (and vice versa), irrespective of the roles of the workers concerned, the authors of CEPR DP6527 show how the change in effort put in by one worker can have either a positive or negative impact on co-workers based purely on income-maximizing considerations.
