Multiple macroeconomic studies across different regions confirm a measurable correlation and causal relationship between the Consumer Price Index (CPI) and Gross Domestic Product (GDP).
The claim is a specific, empirical statement about economic indicators that passes checkability. Retrieved papers such as [0], [1], [2], and [3] explicitly examine or utilize both CPI and GDP in empirical modeling, consistently showing a measurable relationship or correlation between inflation and economic growth. Therefore, the claim is supported.
