Information production from investment social networks around earnings announcements matters to price efficiency. Social networks’ content is excessively optimistic and associated with buying pressure before announcements. Such pressure deviates prices away from fundamentals before negative news and towards fundamentals before positive news. In rare cases of extreme pessimism, we find selling price pressure before positive and negative earnings news. Surges in retail trading and investors’ beliefs susceptible to manipulation amplify these effects. Our results suggest that social networks induce optimistic trading, consistent with a model of wishful thinking

This thesis aims to find evidence of the “fear of floating” in three Latin American countries: Mexico, Chile, and Brazil. By considering the role of the exchange rate in their monetary policy and describing it as an augmented forward-looking Taylor Rule with interest rate smoothing. If the Taylor Rule does not describe the behavior of their target rates, then evidence of “fear of floating” will be found.
