The article discusses how Colombia's current fiscal policy framework may not be effective for making public investment decisions. The author suggests a new dynamic model to analyze the impact of public capital spending on the economy. The results show that cutting public capital spending to reduce deficits can harm economic growth and is not effective for fiscal consolidation. Increasing public capital spending permanently can lead to more tax revenue, but it may also affect infrastructure user charges. Overall, the study highlights the importance of considering long-term sustainability when making public investment decisions in Colombia.
