\section*{Problem 1}
Run a simplified model using the \texttt{tariff.dta} dataset that includes \texttt{tariff} as the dependent and \texttt{polity} and \texttt{gatt} as independent variables. Plot the effect of \texttt{polity} on \texttt{tariff} for GATT members and non-GATT members. How does GATT membership change the predicted values for tariffs?
