Figure 1

The panels display social influence coefficients from second-stage regressions in the two-stage least squares specification for friends’ behaviour at time t influencing ego at time t, t+1 and t+2 for (a) distance ran in kilometres (km), (b) pace in km per minute, (c) running duration in minutes and (d) calories burned. Bars are 95% confidence intervals. (e) The table at the bottom of the figure compares social influence coefficients and s.e. from the IV models to those from the OLS models and provides the OLS overestimates of social influence as a percentage of the IV estimates.
