U.S. Average Egg Price and Producer Price Index Time Series

S1 Data contains time series data on the average price of eggs per dozen and the Producer Price Index (PPI) in the United States. The dataset, authored by Aitor Sarasola-Cullen and last updated in March 2026, is a 70.5 KB XLS file. It was used to analyze long-term behavior, long memory, and cointegration between egg prices and the PPI.

Use Cases

• Test for long memory in price series based on the fractional integration methodology described.
• Analyze mean reversion in the Producer Price Index based on the statistical properties mentioned.
• Investigate cointegration between egg prices and the PPI based on the described equilibrium relationship.
• Model the impact of staple food price changes on consumer purchasing power based on the CPI context provided.

Strengths

• Dataset is focused on a specific, impactful economic indicator (average egg price).
• Analysis described uses established econometric concepts (fractional integration, cointegration).
• File is small (70.5 KB) and in a widely accessible format (XLS).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description is from a paper; the dataset's exact temporal coverage is unspecified.
