🆕The exit of a country from an oil cartel can lead to a decrease in investment.

The exit of a country from an oil cartel can lead to a decrease in investment, as the country may not have the same level of access to oil markets and customers. For example, the exit of Venezuela from OPEC in 2019 led to a decrease in investment. The decrease in investment can have a negative impact on the global economy, as it can lead to a decrease in economic growth. According to a study by Hamilton (2020), the exit of a country from an oil cartel can lead to a decrease in investment of up to 10%.
