This study explores if self-control predicts exercise ambition and actual exercise, and if exercise ambition predicts actual exercise. Members and guests at a not-for-profit sports club were invited to participate. 264 individuals completed a self-reported (Self-Control Scale) measure of self-control, and responded to questions about actual exercise as well as exercise ambition prior to their workout. Main Outcome Measures are exercise ambition, actual exercise, and the difference between them. We find that trait self-control predicts both actual exercise and exercise ambition. Exercise ambition also predicts actual exercise. The results suggest a path from self-control, via exercise ambition, to actual exercise. Individuals with relatively low self-control might benefit from some aid in setting goals for their workouts and committing to exercise.

Prudent use of antibiotics is important to delay the spread of resistance. This paper analyses the effect on children's antibiotics use of a reform of the temporary parental benefit in Sweden. The reform increased the maximum compensation for this benefit. The level of compensation for social security may affect the propensity of a patient or parent to push for a prescription for antibiotics, as a less generous compensation makes it more expensive to be absent from work and since there is widespread overconfidence in the effectiveness of antibiotics. Using municipality level data, we show that the reform resulted in a reduction in children's antibiotics use by about five per cent. The result is fairly robust to alternative empirical strategies, suggesting that welfare policies can have important indirect effects that should be taken into account.
