Wa^alaikum salam Mr. Andry.
Thank you for the questions
1. I collect the data from BPS. The data is secondary data that we can buy from
BPS.
2. I collect data about fuel and electricity consumption of manufacturing firms, the
expenses of energy consumption for each type of fuels, the company consumed, the
value added, and so on. All the data were available from BPS.
3. I collect the data from April 2022 to May 2022.
4. I used the exemplar of Andersson, J (2019) ^Carbon tax and CO2 emission:
Sweden as a case study^. American Economic Journal: Economic Policy. 11(4):1-30,
with some modification
3. I used Stata to run the data.
