Before revision:  We consider sequential social learning with rational agents and Gaussian signals  and ask how the  efficiency of signal aggregation changes with the network . Rational actions in our model  admit a signal-counting interpretation of accuracy ,
After revision:  We consider sequential social learning with rational agents and Gaussian signals in the canonical sequential social-learning problem and ask how the efficiency of signal aggregation changes with the network . Rational actions in our model admit a signal-counting interpretation of accuracy ,
