, we know that the Bureau of Economic Analysis collects Real GDP data on a quarterly basis (Jan, Apr, Jul, Oct). We also know that Bureau of Labor Statistics collects CPI data monthly. From the AD-AS model, we know that price can goes up due to upward shifting of SRAS, or upward shifting of AD curve. Suppose currently (November) the BLS announces the CPI increases from 320 to 323, how can I tell whether this inflation is driven by the SRAS or AD? What kind of data can help us to determine the source of this inflation? (Hint: Think about what data is also collected monthly and go from there)
