This week we examine take a deep dive into what can be learned from examining the unsmoothed data for correlation of deficit spending and CPI inflation. As before, we are looking at the years 2014-2022.

In previous parts of this discussion, we have made some qualitative observations about relationships involving the correlations between U.S. federal government spending and inflation in the U.S. economy. For the first time in this series, we will move into the arena of quantitative measurements of government spending and inflation correlations.

We have previously1 used the CPI data available since 1913 to create annualized inflation data aligned with the federal fiscal years from 1914 to 2022. In this post, we use the timeline-matched data to examine leads or lags that may exist between the two variables – government spending and inflation.

In previous posts on this topic,1,2,3 we have looked at the historical records of inflation and deficit spending by the U.S. federal government. The changing dates for the government’s fiscal year over the country’s history confounded the correlation analysis of that data. Since 1913, U.S. inflation data has been recorded monthly. In this post, we will use the data since 1913 to align the timelines of the two variables.
This post will address how data sampling affects the analysis results for correlations between U.S. deficit spending and inflation. In Part 11of this series, it was seen that there is significant variability in this correlation over time. It is essential to know whether that variability is affected by changing the data sampling structure. If changes are connected to data treatment, care must be taken to ensure conclusions are fundamental to the overall data and not an artifact of how it is organized.

re “Inflation is always and everywhere a monetary phenomenon.”
. – – Milton Friedman1
Note: An updated, expanded, and further edited version has been published here.
Nobel laureate Milton Friedman is considered to be the father of monetarism. This macroeconomic theory enjoyed popularity in the late 20th century but has come under increased criticism in the 21st century. Monetary theory is deeply linked to arguments about the causes of inflation. As shown here, there is little data to support Friedman’s theory that government spending generally causes inflation. The issue is not as simple as he made it seem.
