“…The country fixed effects alone do not address this issue completely given that oil prices and quantities fluctuate, which can cause large CTFP fluctuations even within countries. Although there is no standard definition of fuel exporters, I follow Janus et al (2022), who identify net fossil fuel exporters as countries whose fuel exports from 1970 to 2006 exceeded their imports and 2% of GDP. These countries include Angola, Azerbaijan, Bahrain, Bolivia, Cameroon, Canada, Colombia, Ecuador, Egypt, Gabon, Indonesia, Iran, Iraq, Kazakhstan, Libya, Malaysia, Mexico, Nigeria, Norway, Oman, Qatar, Russia, Saudi Arabia, Sudan, Trinidad &Tobago, Tunisia, Turkmenistan, United Arab Emirates, and Venezuela.…”
