Abstract

This paper explores the importance of time aggregation for labor market fluctuations. Instead of correcting time aggregation bias in the data, we develop a simple search-matching model in which some individuals lose and find a job within a period to artificially generate the bias. The magnitude of time aggregation bias is highly procyclical. An increase in the degree of time aggregation bias is associated with a significantly lower unemployment volatility.
