Hello Everyone,
I am trying to the see the impact of adoption of technology on the firm value. I want to see whether after adopting the technology, there has been increase or decrease in the firm value. I am using PSM to have a treated and matched control sample. However, since the adoption of technology could take place at multiple time and unlike one time year policy adoption, I am facing issues. In other words for the entire time period, a firm may adopt the technology at any time, and not on one single year. That is the reason I am using analysis for every year.
pscore treatmatch size MB ROA if fyear==2005, pscore(myscore) blockid(myblock)
attnd Diff treatmatch size MB ROA if fyear==2005,pscore(myscore) comsup boot dots
This is the code I am using. where treatmatch is the indicator variable whether firm has adopted the technology. Now, I want to see the overall effect of the adoption and not a yearwise impact. As in across all the years what has been the impact of adoption of the techonology on the firm value.
How to do this?
