Before There was Inexpensive Computing …

… there were artists in government agencies drawing time series graphs. As we discuss in this recent blog post, the Bureau of Labor Statistics (BLS) has been in the news lately—undoubtedly much more than the people who work there would like.

This post is not about the current controversy but steps back to make a bigger point: The availability of data has increased tremendously from the time when Glenn and Tony began their academic careers. In the 1980s, personal computers were becoming widespread, but the internet had not yet developed to the point where government statistics were available to download. To gather data usually required a trip to the university library to make photocopies of tables in the print publications of the BLS and other government agencies. You then had to enter the data by hand into very crude—by current standards—spreadsheet and statistical software. The software generally had limited graphing capabilities.

How were the time series figures in print government publications generated? The two photos shown above (both from the website of the Library of Congress) show that the figures were hand drawn by artists. The upper photo is from 1962 and the lower photo is from 1971.

Today, most government data is readily available online. The FRED (Federal Reserve Economic Data) site, hosted by economists at the Federal Reserve Bank of St. Louis makes available thousands of data series. We make use of these series in the Data Exercises included in the end-of-chapter problems in our textbooks. The FRED site makes it easy (we hope!) to do these exercises, including by combining or otherwise transforming data series and by graphing them—no artistic ability required!

Why Were Glenn and Tony Particularly Happy in 2024?

Because inflation in chocolate chip cookie prices ended, or course! In December 2023, the average retail price of a pound of chocolate chip cookies (even we try not to eat a pound of cookies in one sitting!) was $5.12. In November 2024, the price had declined to $4.92 per pound. As the following figure shows, the days of 20 percent annual inflation in chocolate chip cookie inflation that lasted from September 2022 to April 2023 are behind us—at least for now.

The following figure shows annual inflation in overall food prices as measured by the percentage change in the food component of the consumer price index (CPI) from the same month in the previous year. During 2024, food inflation has been running at an annual rate of between 2.0 percent and 2.5 percent. In contrast, chocolate chip cookies actually experienced deflation of –1.1 percent. So, the price of chocolate chip cookies relative to the prices of other food products declined by more than did the absolute price.

We were led to contemplate chocolate chip cookie prices by this article in the New York Times that discusses the FRED data set. (A subscription may be required to access the article.) Like many other economists, we heavily use the FRED site and greatly appreciate the efforts of those at the Federal Reserve Bank of St. Louis who have made this data resource available.
