The study looked at how different types of government spending and taxes affect economic growth in Malaysia from 1970 to 2002. They found that increasing development spending is good for the economy, but indirect taxes can hurt economic activity. Surprisingly, direct taxes like corporate and income taxes actually have a positive impact on output. This means that changing all types of government spending and taxes might not always be the best way to stabilize the economy. It's important for the government to carefully consider which areas to focus on in their budget planning.
