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 and ask how the efficiency of signal aggregation changes with the network . Rational actions in our model are a log-linear function of observations and admit a signal-counting interpretation of accuracy ,
