Let the vertical axis of a figure indicate the average employment fast food restaurants. There are two time periods, t=1 and t=2 , where time period is measured on the horizontal axis. The following table presents average employment levels per restaurant for New Jersey (the treatment group) and Eastern Pennsylvania (the control group).
$\begin{array} { | l | c | c | }
\hline & P A & N J \
\hline \begin{array} { l }
\text { FTE Employment } \
\text { before }
\end{array} & 23.33 & 20.44 \
\hline \begin{array} { l }
\text { FTE Employment } \
\text { after }
\end{array} & 21.17 & 21.03 \
\hline
\end{array}$
Enter the four points in the figure and label them $\bar { Y } ^ { \text {treatment,before } } , \bar { Y } ^ { \text {treatment,after } } , \bar { Y } ^ { \text {cantrol,before } }$ and $\bar { Y } ^ { \text {control, after } }$ . Connect the points. Finally calculate and indicate the value for $\widehat { \beta } _ { 1 } ^ { \text {ditss-in-diffs } } .$
